M. D. Meiklejohn + + + +PREFACE TO THE FIRST EDITION, 1781 + +Human reason, in one sphere of its cognition, is called upon to +consider questions, which it cannot decline, as they are presented +by its own nature, but which it cannot answer, as they transcend every +faculty of the mind. + +It falls into this difficulty without any fault of its own. It +begins with principles, which cannot be dispensed with in the field +of experience, and the truth and sufficiency of which are, at the same +time, insured by experience. With these principles it rises, in +obedience to the laws of its own nature, to ever higher and more +remote conditions. But it quickly discovers that, in this way, its +labours must remain ever incomplete, because new questions never cease +to present themselves; and thus it finds itself compelled to have +recourse to principles which transcend the region of experience, while +they are regarded by common sense without distrust. It thus falls into +confusion and contradictions, from which it conjectures the presence +of latent errors, which, however, it is unable to discover, because +the principles it employs, transcending the limits of experience, +cannot be tested by that criterion. The arena of these endless +contests is called Metaphysic. + +Time was, when she was the queen of all the sciences; and, if we +take the will for the deed, she certainly deserves, so far as +regards the high importance of her object-matter, this title of +honour. Now, it is the fashion of the time to heap contempt and +scorn upon her; and the matron mourns, forlorn and forsaken, like +Hecuba: + + Modo maxima rerum, + Tot generis, natisque potens... + Nunc trahor exul, inops. + -- Ovid, Metamorphoses. xiii + +At first, her government, under the administration of the +dogmatists, was an absolute despotism. But, as the legislative +continued to show traces of the ancient barbaric rule, her empire +gradually broke up, and intestine wars introduced the reign of +anarchy; while the sceptics, like nomadic tribes, who hate a permanent +habitation and settled mode of living, attacked from time to time +those who had organized themselves into civil communities. But their +number was, very happily, small; and thus they could not entirely +put a stop to the exertions of those who persisted in raising new +edifices, although on no settled or uniform plan. In recent times +the hope dawned upon us of seeing those disputes settled, and the +legitimacy of her claims established by a kind of physiology of the +human understanding--that of the celebrated Locke. But it was found +that--although it was affirmed that this so-called queen could not +refer her descent to any higher source than that of common experience, +a circumstance which necessarily brought suspicion on her claims--as +this genealogy was incorrect, she persisted in the advancement of +her claims to sovereignty. Thus metaphysics necessarily fell back into +the antiquated and rotten constitution of dogmatism, and again +became obnoxious to the contempt from which efforts had been made to +save it. At present, as all methods, according to the general +persuasion, have been tried in vain, there reigns nought but weariness +and complete indifferentism--the mother of chaos and night in the +scientific world, but at the same time the source of, or at least +the prelude to, the re-creation and reinstallation of a science, +when it has fallen into confusion, obscurity, and disuse from ill +directed effort. + +For it is in reality vain to profess indifference in regard to +such inquiries, the object of which cannot be indifferent to humanity. +Besides, these pretended indifferentists, however much they may try +to disguise themselves by the assumption of a popular style and by +changes on the language of the schools, unavoidably fall into +metaphysical declarations and propositions, which they profess to +regard with so much contempt. At the same time, this indifference, +which has arisen in the world of science, and which relates to that +kind of knowledge which we should wish to see destroyed the last, is +a phenomenon that well deserves our attention and reflection. It is +plainly not the effect of the levity, but of the matured judgement* +of the age, which refuses to be any longer entertained with illusory +knowledge, It is, in fact, a call to reason, again to undertake the +most laborious of all tasks--that of self-examination, and to +establish a tribunal, which may secure it in its well-grounded claims, +while it pronounces against all baseless assumptions and +pretensions, not in an arbitrary manner, but according to its own +eternal and unchangeable laws. This tribunal is nothing less than +the critical investigation of pure reason. + +[*Footnote: We very often hear complaints of the shallowness of the +present age, and of the decay of profound science. But I do not think +that those which rest upon a secure foundation, such as mathematics, +physical science, etc., in the least deserve this reproach, but that +they rather maintain their ancient fame, and in the latter case, +indeed, far surpass it. The same would be the case with the other +kinds of cognition, if their principles were but firmly established. +In the absence of this security, indifference, doubt, and finally, +severe criticism are rather signs of a profound habit of thought. +Our age is the age of criticism, to which everything must be +subjected. The sacredness of religion, and the authority of +legislation, are by many regarded as grounds of exemption from the +examination of this tribunal. But, if they on they are exempted, +they become the subjects of just suspicion, and cannot lay claim to +sincere respect, which reason accords only to that which has stood +the test of a free and public examination.] + +I do not mean by this a criticism of books and systems, but a +critical inquiry into the faculty of reason, with reference to the +cognitions to which it strives to attain without the aid of +experience; in other words, the solution of the question regarding +the possibility or impossibility of metaphysics, and the determination +of the origin, as well as of the extent and limits of this science. +All this must be done on the basis of principles. + +This path--the only one now remaining--has been entered upon by +me; and I flatter myself that I have, in this way, discovered the +cause of--and consequently the mode of removing--all the errors +which have hitherto set reason at variance with itself, in the +sphere of non-empirical thought. I have not returned an evasive answer +to the questions of reason, by alleging the inability and limitation +of the faculties of the mind; I have, on the contrary, examined them +completely in the light of principles, and, after having discovered +the cause of the doubts and contradictions into which reason fell, +have solved them to its perfect satisfaction. It is true, these +questions have not been solved as dogmatism, in its vain fancies and +desires, had expected; for it can only be satisfied by the exercise +of magical arts, and of these I have no knowledge. But neither do these +come within the compass of our mental powers; and it was the duty of +philosophy to destroy the illusions which had their origin in +misconceptions, whatever darling hopes and valued expectations may +be ruined by its explanations. My chief aim in this work has been +thoroughness; and I make bold to say that there is not a single +metaphysical problem that does not find its solution, or at least +the key to its solution, here. Pure reason is a perfect unity; and +therefore, if the principle presented by it prove to be insufficient +for the solution of even a single one of those questions to which +the very nature of reason gives birth, we must reject it, as we could +not be perfectly certain of its sufficiency in the case of the others. + +While I say this, I think I see upon the countenance of the reader +signs of dissatisfaction mingled with contempt, when he hears +declarations which sound so boastful and extravagant; and yet they +are beyond comparison more moderate than those advanced by the commonest +author of the commonest philosophical programme, in which the +dogmatist professes to demonstrate the simple nature of the soul, or +the necessity of a primal being. Such a dogmatist promises to extend +human knowledge beyond the limits of possible experience; while I +humbly confess that this is completely beyond my power. Instead of +any such attempt, I confine myself to the examination of reason alone +and its pure thought; and I do not need to seek far for the +sum-total of its cognition, because it has its seat in my own mind. +Besides, common logic presents me with a complete and systematic +catalogue of all the simple operations of reason; and it is my task +to answer the question how far reason can go, without the material +presented and the aid furnished by experience. + +So much for the completeness and thoroughness necessary in the +execution of the present task. The aims set before us are not +arbitrarily proposed, but are imposed upon us by the nature of +cognition itself. + +The above remarks relate to the matter of our critical inquiry. As +regards the form, there are two indispensable conditions, which any +one who undertakes so difficult a task as that of a critique of pure +reason, is bound to fulfil. These conditions are certitude and +clearness. + +As regards certitude, I have fully convinced myself that, in this +sphere of thought, opinion is perfectly inadmissible, and that +everything which bears the least semblance of an hypothesis must be +excluded, as of no value in such discussions. For it is a necessary +condition of every cognition that is to be established upon a priori +grounds that it shall be held to be absolutely necessary; much more +is this the case with an attempt to determine all pure a priori +cognition, and to furnish the standard--and consequently an example-- +of all apodeictic (philosophical) certitude. Whether I have +succeeded in what I professed to do, it is for the reader to +determine; it is the author's business merely to adduce grounds and +reasons, without determining what influence these ought to have on +the mind of his judges. But, lest anything he may have said may become +the innocent cause of doubt in their minds, or tend to weaken the effect +which his arguments might otherwise produce--he may be allowed to +point out those passages which may occasion mistrust or difficulty, +although these do not concern the main purpose of the present work. +He does this solely with the view of removing from the mind of the +reader any doubts which might affect his judgement of the work as a +whole, and in regard to its ultimate aim. + +I know no investigations more necessary for a full insight into +the nature of the faculty which we call understanding, and at the same +time for the determination of the rules and limits of its use, than +those undertaken in the second chapter of the "Transcendental +Analytic," under the title of "Deduction of the Pure Conceptions of +the Understanding"; and they have also cost me by far the greatest +labour--labour which, I hope, will not remain uncompensated. The +view there taken, which goes somewhat deeply into the subject, has +two sides, The one relates to the objects of the pure understanding, +and is intended to demonstrate and to render comprehensible the +objective validity of its a priori conceptions; and it forms for +this reason an essential part of the Critique. The other considers +the pure understanding itself, its possibility and its powers of +cognition--that is, from a subjective point of view; and, although +this exposition is of great importance, it does not belong essentially +to the main purpose of the work, because the grand question is what +and how much can reason and understanding, apart from experience, +cognize, and not, how is the faculty of thought itself possible? As +the latter is an inquiry into the cause of a given effect, and has +thus in it some semblance of an hypothesis (although, as I shall +show on another occasion, this is really not the fact), it would +seem that, in the present instance, I had allowed myself to enounce +a mere opinion, and that the reader must therefore be at liberty to +hold a different opinion. But I beg to remind him that, if my +subjective deduction does not produce in his mind the conviction of +its certitude at which I aimed, the objective deduction, with which +alone the present work is properly concerned, is in every respect +satisfactory. + +As regards clearness, the reader has a right to demand, in the first +place, discursive or logical clearness, that is, on the basis of +conceptions, and, secondly, intuitive or aesthetic clearness, by means +of intuitions, that is, by examples or other modes of illustration +in concreto. I have done what I could for the first kind of +intelligibility. This was essential to my purpose; and it thus +became the accidental cause of my inability to do complete justice +to the second requirement. I have been almost always at a loss, during +the progress of this work, how to settle this question. Examples and +illustrations always appeared to me necessary, and, in the first +sketch of the Critique, naturally fell into their proper places. But +I very soon became aware of the magnitude of my task, and the numerous +problems with which I should be engaged; and, as I perceived that this +critical investigation would, even if delivered in the driest +scholastic manner, be far from being brief, I found it unadvisable +to enlarge it still more with examples and explanations, which are +necessary only from a popular point of view. I was induced to take +this course from the consideration also that the present work is not +intended for popular use, that those devoted to science do not require +such helps, although they are always acceptable, and that they would +have materially interfered with my present purpose. Abbe Terrasson +remarks with great justice that, if we estimate the size of a work, +not from the number of its pages, but from the time which we require +to make ourselves master of it, it may be said of many a book that +it would be much shorter, if it were not so short. On the other +hand, as regards the comprehensibility of a system of speculative +cognition, connected under a single principle, we may say with equal +justice: many a book would have been much clearer, if it had not +been intended to be so very clear. For explanations and examples, +and other helps to intelligibility, aid us in the comprehension of +parts, but they distract the attention, dissipate the mental power +of the reader, and stand in the way of his forming a clear +conception of the whole; as he cannot attain soon enough to a survey +of the system, and the colouring and embellishments bestowed upon it +prevent his observing its articulation or organization--which is the +most important consideration with him, when he comes to judge of its +unity and stability. + +The reader must naturally have a strong inducement to co-operate +with the present author, if he has formed the intention of erecting +a complete and solid edifice of metaphysical science, according to +the plan now laid before him. Metaphysics, as here represented, is +the only science which admits of completion--and with little labour, +if it is united, in a short time; so that nothing will be left to future +generations except the task of illustrating and applying it +didactically. For this science is nothing more than the inventory of +all that is given us by pure reason, systematically arranged. +Nothing can escape our notice; for what reason produces from itself +cannot lie concealed, but must be brought to the light by reason +itself, so soon as we have discovered the common principle of the +ideas we seek. The perfect unity of this kind of cognitions, which +are based upon pure conceptions, and uninfluenced by any empirical +element, or any peculiar intuition leading to determinate +experience, renders this completeness not only practicable, but also +necessary. + + Tecum habita, et noris quam sit tibi curta supellex. + -- Persius.

In the present work, I look for the patient hearing and the +impartiality of a judge; in the other, for the good-will and +assistance of a co-labourer.

If we find those who are engaged in +metaphysical pursuits, unable to come to an understanding as to the +method which they ought to follow; if we find them, after the most +elaborate preparations, invariably brought to a stand before the +goal is reached, and compelled to retrace their steps and strike +into fresh paths, we may then feel quite sure that they are far from +having attained to the certainty of scientific progress and may rather +be said to be merely groping about in the dark. In these circumstances +we shall render an important service to reason if we succeed in simply +indicating the path along which it must travel, in order to arrive +at any results--even if it should be found necessary to abandon many +of those aims which, without reflection, have been proposed for its +attainment. + +That logic has advanced in this sure course, even from the +earliest times, is apparent from the fact that, since Aristotle, it +has been unable to advance a step and, thus, to all appearance has +reached its completion. For, if some of the moderns have thought to +enlarge its domain by introducing psychological discussions on the +mental faculties, such as imagination and wit, metaphysical, +discussions on the origin of knowledge and the different kinds of +certitude, according to the difference of the objects (idealism, +scepticism, and so on), or anthropological discussions on +prejudices, their causes and remedies: this attempt, on the part of +these authors, only shows their ignorance of the peculiar nature of +logical science. We do not enlarge but disfigure the sciences when +we lose sight of their respective limits and allow them to run into +one another. Now logic is enclosed within limits which admit of +perfectly clear definition; it is a science which has for its object +nothing but the exposition and proof of the formal laws of all +thought, whether it be a priori or empirical, whatever be its origin +or its object, and whatever the difficulties--natural or accidental-- +which it encounters in the human mind. + +The early success of logic must be attributed exclusively to the +narrowness of its field, in which abstraction may, or rather must, +be made of all the objects of cognition with their characteristic +distinctions, and in which the understanding has only to deal with +itself and with its own forms. It is, obviously, a much more difficult +task for reason to strike into the sure path of science, where it +has to deal not simply with itself, but with objects external to +itself. Hence, logic is properly only a propaedeutic--forms, as it +were, the vestibule of the sciences; and while it is necessary to +enable us to form a correct judgement with regard to the various +branches of knowledge, still the acquisition of real, substantive +knowledge is to be sought only in the sciences properly so called, +that is, in the objective sciences. + +Now these sciences, if they can be termed rational at all, must +contain elements of a priori cognition, and this cognition may stand +in a twofold relation to its object. Either it may have to determine +the conception of the object--which must be supplied extraneously, +or it may have to establish its reality. The former is theoretical, +the latter practical, rational cognition. In both, the pure or a +priori element must be treated first, and must be carefully +distinguished from that which is supplied from other sources. Any +other method can only lead to irremediable confusion. + +Mathematics and physics are the two theoretical sciences which +have to determine their objects a priori. The former is purely a +priori, the latter is partially so, but is also dependent on other +sources of cognition. + +In the earliest times of which history affords us any record, +mathematics had already entered on the sure course of science, among +that wonderful nation, the Greeks. Still it is not to be supposed that +it was as easy for this science to strike into, or rather to construct +for itself, that royal road, as it was for logic, in which reason +has only to deal with itself. On the contrary, I believe that it +must have remained long--chiefly among the Egyptians--in the stage +of blind groping after its true aims and destination, and that it +was revolutionized by the happy idea of one man, who struck out and +determined for all time the path which this science must follow, and +which admits of an indefinite advancement. The history of this +intellectual revolution--much more important in its results than the +discovery of the passage round the celebrated Cape of Good Hope--and +of its author, has not been preserved. But Diogenes Laertius, in +naming the supposed discoverer of some of the simplest elements of +geometrical demonstration--elements which, according to the ordinary +opinion, do not even require to be proved--makes it apparent that +the change introduced by the first indication of this new path, must +have seemed of the utmost importance to the mathematicians of that +age, and it has thus been secured against the chance of oblivion. A +new light must have flashed on the mind of the first man (Thales, or +whatever may have been his name) who demonstrated the properties of +the isosceles triangle. For he found that it was not sufficient to +meditate on the figure, as it lay before his eyes, or the conception +of it, as it existed in his mind, and thus endeavour to get at the +knowledge of its properties, but that it was necessary to produce +these properties, as it were, by a positive a priori construction; +and that, in order to arrive with certainty at a priori cognition, +he must not attribute to the object any other properties than those +which necessarily followed from that which he had himself, in accordance +with his conception, placed in the object. + +A much longer period elapsed before physics entered on the highway +of science. For it is only about a century and a half since the wise +Bacon gave a new direction to physical studies, or rather--as others +were already on the right track--imparted fresh vigour to the +pursuit of this new direction. Here, too, as in the case of +mathematics, we find evidence of a rapid intellectual revolution. In +the remarks which follow I shall confine myself to the empirical +side of natural science. + +When Galilei experimented with balls of a definite weight on the +inclined plane, when Torricelli caused the air to sustain a weight +which he had calculated beforehand to be equal to that of a definite +column of water, or when Stahl, at a later period, converted metals +into lime, and reconverted lime into metal, by the addition and +subtraction of certain elements; [Footnote: I do not here follow +with exactness the history of the experimental method, of which, +indeed, the first steps are involved in some obscurity.] a light broke +upon all natural philosophers. They learned that reason only perceives +that which it produces after its own design; that it must not be content +to follow, as it were, in the leading-strings of nature, but must proceed +in advance with principles of judgement according to unvarying laws, +and compel nature to reply its questions. For accidental observations, +made according to no preconceived plan, cannot be united under a +necessary law. But it is this that reason seeks for and requires. It +is only the principles of reason which can give to concordant +phenomena the validity of laws, and it is only when experiment is +directed by these rational principles that it can have any real +utility. Reason must approach nature with the view, indeed, of +receiving information from it, not, however, in the character of a +pupil, who listens to all that his master chooses to tell him, but +in that of a judge, who compels the witnesses to reply to those +questions which he himself thinks fit to propose. To this single +idea must the revolution be ascribed, by which, after groping in the +dark for so many centuries, natural science was at length conducted +into the path of certain progress. + +We come now to metaphysics, a purely speculative science, which +occupies a completely isolated position and is entirely independent +of the teachings of experience. It deals with mere conceptions--not, +like mathematics, with conceptions applied to intuition--and in it, +reason is the pupil of itself alone. It is the oldest of the sciences, +and would still survive, even if all the rest were swallowed up in +the abyss of an all-destroying barbarism. But it has not yet had the +good fortune to attain to the sure scientific method. This will be +apparent; if we apply the tests which we proposed at the outset. We +find that reason perpetually comes to a stand, when it attempts to +gain a priori the perception even of those laws which the most +common experience confirms. We find it compelled to retrace its +steps in innumerable instances, and to abandon the path on which it +had entered, because this does not lead to the desired result. We +find, too, that those who are engaged in metaphysical pursuits are +far from being able to agree among themselves, but that, on the +contrary, this science appears to furnish an arena specially adapted +for the display of skill or the exercise of strength in mock-contests-- +a field in which no combatant ever yet succeeded in gaining an inch +of ground, in which, at least, no victory was ever yet crowned with +permanent possession. + +This leads us to inquire why it is that, in metaphysics, the sure +path of science has not hitherto been found. Shall we suppose that +it is impossible to discover it? Why then should nature have visited +our reason with restless aspirations after it, as if it were one of +our weightiest concerns? Nay, more, how little cause should we have +to place confidence in our reason, if it abandons us in a matter about +which, most of all, we desire to know the truth--and not only so, +but even allures us to the pursuit of vain phantoms, only to betray +us in the end? Or, if the path has only hitherto been missed, what +indications do we possess to guide us in a renewed investigation, +and to enable us to hope for greater success than has fallen to the +lot of our predecessors? + +It appears to me that the examples of mathematics and natural +philosophy, which, as we have seen, were brought into their present +condition by a sudden revolution, are sufficiently remarkable to fix +our attention on the essential circumstances of the change which has +proved so advantageous to them, and to induce us to make the +experiment of imitating them, so far as the analogy which, as rational +sciences, they bear to metaphysics may permit. It has hitherto been +assumed that our cognition must conform to the objects; but all +attempts to ascertain anything about these objects a priori, by +means of conceptions, and thus to extend the range of our knowledge, +have been rendered abortive by this assumption. Let us then make the +experiment whether we may not be more successful in metaphysics, if +we assume that the objects must conform to our cognition. This appears, +at all events, to accord better with the possibility of our gaining +the end we have in view, that is to say, of arriving at the +cognition of objects a priori, of determining something with respect +to these objects, before they are given to us. We here propose to do +just what Copernicus did in attempting to explain the celestial +movements. When he found that he could make no progress by assuming +that all the heavenly bodies revolved round the spectator, he reversed +the process, and tried the experiment of assuming that the spectator +revolved, while the stars remained at rest. We may make the same +experiment with regard to the intuition of objects. If the intuition +must conform to the nature of the objects, I do not see how we can +know anything of them a priori. If, on the other hand, the object +conforms to the nature of our faculty of intuition, I can then +easily conceive the possibility of such an a priori knowledge. Now +as I cannot rest in the mere intuitions, but--if they are to become +cognitions--must refer them, as representations, to something, as +object, and must determine the latter by means of the former, here +again there are two courses open to me. Either, first, I may assume +that the conceptions, by which I effect this determination, conform +to the object--and in this case I am reduced to the same perplexity +as before; or secondly, I may assume that the objects, or, which is +the same thing, that experience, in which alone as given objects they +are cognized, conform to my conceptions--and then I am at no loss +how to proceed. For experience itself is a mode of cognition which +requires understanding. Before objects, are given to me, that is, a +priori, I must presuppose in myself laws of the understanding which +are expressed in conceptions a priori. To these conceptions, then, +all the objects of experience must necessarily conform. Now there are +objects which reason thinks, and that necessarily, but which cannot +be given in experience, or, at least, cannot be given so as reason +thinks them. The attempt to think these objects will hereafter furnish +an excellent test of the new method of thought which we have adopted, +and which is based on the principle that we only cognize in things +a priori that which we ourselves place in them.* + +[*Footnote: This method, accordingly, which we have borrowed from the +natural philosopher, consists in seeking for the elements of pure reason +in that which admits of confirmation or refutation by experiment. Now +the propositions of pure reason, especially when they transcend the +limits of possible experience, do not admit of our making any experiment +with their objects, as in natural science. Hence, with regard to those +conceptions and principles which we assume a priori, our only course +ill be to view them from two different sides. We must regard one and +the same conception, on the one hand, in relation to experience as +an object of the senses and of the understanding, on the other hand, +in relation to reason, isolated and transcending the limits of +experience, as an object of mere thought. Now if we find that, when +we regard things from this double point of view, the result is in harmony +with the principle of pure reason, but that, when we regard them +from a single point of view, reason is involved in self-contradiction, +then the experiment will establish the correctness of this +distinction.] + +This attempt succeeds as well as we could desire, and promises to +metaphysics, in its first part--that is, where it is occupied with +conceptions a priori, of which the corresponding objects may be +given in experience--the certain course of science. For by this new +method we are enabled perfectly to explain the possibility of a priori +cognition, and, what is more, to demonstrate satisfactorily the laws +which lie a priori at the foundation of nature, as the sum of the +objects of experience--neither of which was possible according to +the procedure hitherto followed. But from this deduction of the +faculty of a priori cognition in the first part of metaphysics, we +derive a surprising result, and one which, to all appearance, +militates against the great end of metaphysics, as treated in the +second part. For we come to the conclusion that our faculty of +cognition is unable to transcend the limits of possible experience; +and yet this is precisely the most essential object of this science. +The estimate of our rational cognition a priori at which we arrive +is that it has only to do with phenomena, and that things in +themselves, while possessing a real existence, lie beyond its +sphere. Here we are enabled to put the justice of this estimate to +the test. For that which of necessity impels us to transcend the limits +of experience and of all phenomena is the unconditioned, which reason +absolutely requires in things as they are in themselves, in order to +complete the series of conditions. Now, if it appears that when, on +the one hand, we assume that our cognition conforms to its objects +as things in themselves, the unconditioned cannot be thought without +contradiction, and that when, on the other hand, we assume that our +representation of things as they are given to us, does not conform +to these things as they are in themselves, but that these objects, +as phenomena, conform to our mode of representation, the contradiction +disappears: we shall then be convinced of the truth of that which we +began by assuming for the sake of experiment; we may look upon it as +established that the unconditioned does not lie in things as we know +them, or as they are given to us, but in things as they are in +themselves, beyond the range of our cognition.* + +[*Footnote: This experiment of pure reason has a great similarity to +that of the chemists, which they term the experiment of reduction, +or, more usually, the synthetic process. The analysis of the metaphysician +separates pure cognition a priori into two heterogeneous elements, +viz., the cognition of things as phenomena, and of things in +themselves. Dialectic combines these again into harmony with the +necessary rational idea of the unconditioned, and finds that this +harmony never results except through the above distinction, which +is, therefore, concluded to be just.] + +But, after we have thus denied the power of speculative reason to +make any progress in the sphere of the supersensible, it still remains +for our consideration whether data do not exist in practical cognition +which may enable us to determine the transcendent conception of the +unconditioned, to rise beyond the limits of all possible experience +from a practical point of view, and thus to satisfy the great ends +of metaphysics. Speculative reason has thus, at least, made room for +such an extension of our knowledge: and, if it must leave this space +vacant, still it does not rob us of the liberty to fill it up, if we +can, by means of practical data--nay, it even challenges us to make +the attempt.* + +[*Footnote: So the central laws of the movements of the heavenly bodies +established the truth of that which Copernicus, first, assumed only +as a hypothesis, and, at the same time, brought to light that invisible +force (Newtonian attraction) which holds the universe together. The +latter would have remained forever undiscovered, if Copernicus had +not ventured on the experiment--contrary to the senses but still just-- +of looking for the observed movements not in the heavenly bodies, +but in the spectator. In this Preface I treat the new metaphysical +method as a hypothesis with the view of rendering apparent the first +attempts at such a change of method, which are always hypothetical. +But in the Critique itself it will be demonstrated, not +hypothetically, but apodeictically, from the nature of our +representations of space and time, and from the elementary conceptions +of the understanding.] + +This attempt to introduce a complete revolution in the procedure +of metaphysics, after the example of the geometricians and natural +philosophers, constitutes the aim of the Critique of Pure +Speculative Reason. It is a treatise on the method to be followed, +not a system of the science itself. But, at the same time, it marks +out and defines both the external boundaries and the internal structure +of this science. For pure speculative reason has this peculiarity, +that, in choosing the various objects of thought, it is able to define +the limits of its own faculties, and even to give a complete +enumeration of the possible modes of proposing problems to itself, +and thus to sketch out the entire system of metaphysics. For, on the +one hand, in cognition a priori, nothing must be attributed to the +objects but what the thinking subject derives from itself; and, on +the other hand, reason is, in regard to the principles of cognition, +a perfectly distinct, independent unity, in which, as in an organized +body, every member exists for the sake of the others, and all for the +sake of each, so that no principle can be viewed, with safety, in one +relationship, unless it is, at the same time, viewed in relation to +the total use of pure reason. Hence, too, metaphysics has this +singular advantage--an advantage which falls to the lot of no other +science which has to do with objects--that, if once it is conducted +into the sure path of science, by means of this criticism, it can then +take in the whole sphere of its cognitions, and can thus complete +its work, and leave it for the use of posterity, as a capital which +can never receive fresh accessions. For metaphysics has to deal only +with principles and with the limitations of its own employment as +determined by these principles. To this perfection it is, therefore, +bound, as the fundamental science, to attain, and to it the maxim +may justly be applied: + + Nil actum reputans, si quid superesset agendum. + +But, it will be asked, what kind of a treasure is this that we +propose to bequeath to posterity? What is the real value of this +system of metaphysics, purified by criticism, and thereby reduced to +a permanent condition? A cursory view of the present work will lead +to the supposition that its use is merely negative, that it only serves +to warn us against venturing, with speculative reason, beyond the +limits of experience. This is, in fact, its primary use. But this, +at once, assumes a positive value, when we observe that the principles +with which speculative reason endeavours to transcend its limits +lead inevitably, not to the extension, but to the contraction of the +use of reason, inasmuch as they threaten to extend the limits of +sensibility, which is their proper sphere, over the entire realm of +thought and, thus, to supplant the pure (practical) use of reason. +So far, then, as this criticism is occupied in confining speculative +reason within its proper bounds, it is only negative; but, inasmuch +as it thereby, at the same time, removes an obstacle which impedes +and even threatens to destroy the use of practical reason, it possesses +a positive and very important value. In order to admit this, we have +only to be convinced that there is an absolutely necessary use of pure +reason--the moral use--in which it inevitably transcends the limits +of sensibility, without the aid of speculation, requiring only to be +insured against the effects of a speculation which would involve it +in contradiction with itself. To deny the positive advantage of the +service which this criticism renders us would be as absurd as to +maintain that the system of police is productive of no positive +benefit, since its main business is to prevent the violence which +citizen has to apprehend from citizen, that so each may pursue his +vocation in peace and security. That space and time are only forms +of sensible intuition, and hence are only conditions of the +existence of things as phenomena; that, moreover, we have no +conceptions of the understanding, and, consequently, no elements for +the cognition of things, except in so far as a corresponding intuition +can be given to these conceptions; that, accordingly, we can have no +cognition of an object, as a thing in itself, but only as an object +of sensible intuition, that is, as phenomenon--all this is proved in +the analytical part of the Critique; and from this the limitation of +all possible speculative cognition to the mere objects of +experience, follows as a necessary result. At the same time, it must +be carefully borne in mind that, while we surrender the power of +cognizing, we still reserve the power of thinking objects, as things +in themselves.* For, otherwise, we should require to affirm the +existence of an appearance, without something that appears--which +would be absurd. Now let us suppose, for a moment, that we had not +undertaken this criticism and, accordingly, had not drawn the +necessary distinction between things as objects of experience and +things as they are in themselves. The principle of causality, and, +by consequence, the mechanism of nature as determined by causality, +would then have absolute validity in relation to all things as +efficient causes. I should then be unable to assert, with regard to +one and the same being, e.g., the human soul, that its will is free, +and yet, at the same time, subject to natural necessity, that is, +not free, without falling into a palpable contradiction, for in both +propositions I should take the soul in the same signification, as a +thing in general, as a thing in itself--as, without previous +criticism, I could not but take it. Suppose now, on the other hand, +that we have undertaken this criticism, and have learnt that an object +may be taken in two senses, first, as a phenomenon, secondly, as a +thing in itself; and that, according to the deduction of the +conceptions of the understanding, the principle of causality has +reference only to things in the first sense. We then see how it does +not involve any contradiction to assert, on the one hand, that the +will, in the phenomenal sphere--in visible action--is necessarily +obedient to the law of nature, and, in so far, not free; and, on the +other hand, that, as belonging to a thing in itself, it is not subject +to that law, and, accordingly, is free. Now, it is true that I cannot, +by means of speculative reason, and still less by empirical +observation, cognize my soul as a thing in itself and consequently, +cannot cognize liberty as the property of a being to which I ascribe +effects in the world of sense. For, to do so, I must cognize this +being as existing, and yet not in time, which--since I cannot +support my conception by any intuition--is impossible. At the same +time, while I cannot cognize, I can quite well think freedom, that +is to say, my representation of it involves at least no contradiction, +if we bear in mind the critical distinction of the two modes of +representation (the sensible and the intellectual) and the +consequent limitation of the conceptions of the pure understanding +and of the principles which flow from them. Suppose now that morality +necessarily presupposed liberty, in the strictest sense, as a property +of our will; suppose that reason contained certain practical, original +principles a priori, which were absolutely impossible without this +presupposition; and suppose, at the same time, that speculative reason +had proved that liberty was incapable of being thought at all. It +would then follow that the moral presupposition must give way to the +speculative affirmation, the opposite of which involves an obvious +contradiction, and that liberty and, with it, morality must yield to +the mechanism of nature; for the negation of morality involves no +contradiction, except on the presupposition of liberty. Now morality +does not require the speculative cognition of liberty; it is enough +that I can think it, that its conception involves no contradiction, +that it does not interfere with the mechanism of nature. But even this +requirement we could not satisfy, if we had not learnt the twofold +sense in which things may be taken; and it is only in this way that +the doctrine of morality and the doctrine of nature are confined +within their proper limits. For this result, then, we are indebted +to a criticism which warns us of our unavoidable ignorance with regard +to things in themselves, and establishes the necessary limitation of +our theoretical cognition to mere phenomena. + +[*Footnote: In order to cognize an object, I must be able to prove +its possibility, either from its reality as attested by experience, +or a priori, by means of reason. But I can think what I please, provided +only I do not contradict myself; that is, provided my conception is +a possible thought, though I may be unable to answer for the existence +of a corresponding object in the sum of possibilities. But something +more is required before I can attribute to such a conception objective +validity, that is real possibility--the other possibility being merely +logical. We are not, however, confined to theoretical sources of +cognition for the means of satisfying this additional requirement, +but may derive them from practical sources.] + +The positive value of the critical principles of pure reason in +relation to the conception of God and of the simple nature of the +soul, admits of a similar exemplification; but on this point I shall +not dwell. I cannot even make the assumption--as the practical +interests of morality require--of God, freedom, and immortality, if +I do not deprive speculative reason of its pretensions to transcendent +insight. For to arrive at these, it must make use of principles which, +in fact, extend only to the objects of possible experience, and +which cannot be applied to objects beyond this sphere without +converting them into phenomena, and thus rendering the practical +extension of pure reason impossible. I must, therefore, abolish +knowledge, to make room for belief. The dogmatism of metaphysics, that +is, the presumption that it is possible to advance in metaphysics +without previous criticism, is the true source of the unbelief (always +dogmatic) which militates against morality. + +Thus, while it may be no very difficult task to bequeath a legacy to +posterity, in the shape of a system of metaphysics constructed in +accordance with the Critique of Pure Reason, still the value of such +a bequest is not to be depreciated. It will render an important +service to reason, by substituting the certainty of scientific +method for that random groping after results without the guidance of +principles, which has hitherto characterized the pursuit of +metaphysical studies. It will render an important service to the +inquiring mind of youth, by leading the student to apply his powers +to the cultivation of genuine science, instead of wasting them, as +at present, on speculations which can never lead to any result, or +on the idle attempt to invent new ideas and opinions. But, above all, +it will confer an inestimable benefit on morality and religion, by +showing that all the objections urged against them may be silenced +for ever by the Socratic method, that is to say, by proving the ignorance +of the objector. For, as the world has never been, and, no doubt, never +will be without a system of metaphysics of one kind or another, it +is the highest and weightiest concern of philosophy to render it +powerless for harm, by closing up the sources of error. + +This important change in the field of the sciences, this loss of its +fancied possessions, to which speculative reason must submit, does +not prove in any way detrimental to the general interests of humanity. +The advantages which the world has derived from the teachings of pure +reason are not at all impaired. The loss falls, in its whole extent, +on the monopoly of the schools, but does not in the slightest degree +touch the interests of mankind. I appeal to the most obstinate +dogmatist, whether the proof of the continued existence of the soul +after death, derived from the simplicity of its substance; of the +freedom of the will in opposition to the general mechanism of +nature, drawn from the subtle but impotent distinction of subjective +and objective practical necessity; or of the existence of God, deduced +from the conception of an ens realissimum--the contingency of the +changeable, and the necessity of a prime mover, has ever been able +to pass beyond the limits of the schools, to penetrate the public +mind, or to exercise the slightest influence on its convictions. It +must be admitted that this has not been the case and that, owing to +the unfitness of the common understanding for such subtle +speculations, it can never be expected to take place. On the contrary, +it is plain that the hope of a future life arises from the feeling, +which exists in the breast of every man, that the temporal is +inadequate to meet and satisfy the demands of his nature. In like +manner, it cannot be doubted that the clear exhibition of duties in +opposition to all the claims of inclination, gives rise to the +consciousness of freedom, and that the glorious order, beauty, and +providential care, everywhere displayed in nature, give rise to the +belief in a wise and great Author of the Universe. Such is the genesis +of these general convictions of mankind, so far as they depend on +rational grounds; and this public property not only remains +undisturbed, but is even raised to greater importance, by the doctrine +that the schools have no right to arrogate to themselves a more +profound insight into a matter of general human concernment than +that to which the great mass of men, ever held by us in the highest +estimation, can without difficulty attain, and that the schools +should, therefore, confine themselves to the elaboration of these +universally comprehensible and, from a moral point of view, amply +satisfactory proofs. The change, therefore, affects only the +arrogant pretensions of the schools, which would gladly retain, in +their own exclusive possession, the key to the truths which they +impart to the public. + +Quod mecum nescit, solus vult scire videri. + +At the same time it does not deprive the speculative philosopher of +his just title to be the sole depositor of a science which benefits +the public without its knowledge--I mean, the Critique of Pure Reason. +This can never become popular and, indeed, has no occasion to be so; +for finespun arguments in favour of useful truths make just as +little impression on the public mind as the equally subtle +objections brought against these truths. On the other hand, since both +inevitably force themselves on every man who rises to the height of +speculation, it becomes the manifest duty of the schools to enter upon +a thorough investigation of the rights of speculative reason and, +thus, to prevent the scandal which metaphysical controversies are +sure, sooner or later, to cause even to the masses. It is only by +criticism that metaphysicians (and, as such, theologians too) can be +saved from these controversies and from the consequent perversion of +their doctrines. Criticism alone can strike a blow at the root of +materialism, fatalism, atheism, free-thinking, fanaticism, and +superstition, which are universally injurious--as well as of +idealism and scepticism, which are dangerous to the schools, but can +scarcely pass over to the public. If governments think proper to +interfere with the affairs of the learned, it would be more consistent +with a wise regard for the interests of science, as well as for +those of society, to favour a criticism of this kind, by which alone +the labours of reason can be established on a firm basis, than to +support the ridiculous despotism of the schools, which raise a loud +cry of danger to the public over the destruction of cobwebs, of +which the public has never taken any notice, and the loss of which, +therefore, it can never feel. + +This critical science is not opposed to the dogmatic procedure of +reason in pure cognition; for pure cognition must always be +dogmatic, that is, must rest on strict demonstration from sure +principles a priori--but to dogmatism, that is, to the presumption +that it is possible to make any progress with a pure cognition, +derived from (philosophical) conceptions, according to the +principles which reason has long been in the habit of employing-- +without first inquiring in what way and by what right reason has +come into the possession of these principles. Dogmatism is thus the +dogmatic procedure of pure reason without previous criticism of its +own powers, and in opposing this procedure, we must not be supposed +to lend any countenance to that loquacious shallowness which arrogates +to itself the name of popularity, nor yet to scepticism, which makes +short work with the whole science of metaphysics. On the contrary, +our criticism is the necessary preparation for a thoroughly scientific +system of metaphysics which must perform its task entirely a priori, +to the complete satisfaction of speculative reason, and must, +therefore, be treated, not popularly, but scholastically. In +carrying out the plan which the Critique prescribes, that is, in the +future system of metaphysics, we must have recourse to the strict +method of the celebrated Wolf, the greatest of all dogmatic +philosophers. He was the first to point out the necessity of +establishing fixed principles, of clearly defining our conceptions, +and of subjecting our demonstrations to the most severe scrutiny, +instead of rashly jumping at conclusions. The example which he set +served to awaken that spirit of profound and thorough investigation +which is not yet extinct in Germany. He would have been peculiarly +well fitted to give a truly scientific character to metaphysical +studies, had it occurred to him to prepare the field by a criticism +of the organum, that is, of pure reason itself. That he failed to +perceive the necessity of such a procedure must be ascribed to the +dogmatic mode of thought which characterized his age, and on this +point the philosophers of his time, as well as of all previous +times, have nothing to reproach each other with. Those who reject at +once the method of Wolf, and of the Critique of Pure Reason, can +have no other aim but to shake off the fetters of science, to change +labour into sport, certainty into opinion, and philosophy into +philodoxy. + +In this second edition, I have endeavoured, as far as possible, to +remove the difficulties and obscurity which, without fault of mine +perhaps, have given rise to many misconceptions even among acute +thinkers. In the propositions themselves, and in the demonstrations +by which they are supported, as well as in the form and the entire +plan of the work, I have found nothing to alter; which must be attributed +partly to the long examination to which I had subjected the whole +before offering it to the public and partly to the nature of the case. +For pure speculative reason is an organic structure in which there +is nothing isolated or independent, but every Single part is essential +to all the rest; and hence, the slightest imperfection, whether defect +or positive error, could not fail to betray itself in use. I +venture, further, to hope, that this system will maintain the same +unalterable character for the future. I am led to entertain this +confidence, not by vanity, but by the evidence which the equality of +the result affords, when we proceed, first, from the simplest elements +up to the complete whole of pure reason and, and then, backwards +from the whole to each part. We find that the attempt to make the +slightest alteration, in any part, leads inevitably to contradictions, +not merely in this system, but in human reason itself. At the same +time, there is still much room for improvement in the exposition of +the doctrines contained in this work. In the present edition, I have +endeavoured to remove misapprehensions of the aesthetical part, +especially with regard to the conception of time; to clear away the +obscurity which has been found in the deduction of the conceptions +of the understanding; to supply the supposed want of sufficient +evidence in the demonstration of the principles of the pure +understanding; and, lastly, to obviate the misunderstanding of the +paralogisms which immediately precede the rational psychology. +Beyond this point--the end of the second main division of the +"Transcendental Dialectic"--I have not extended my alterations,* +partly from want of time, and partly because I am not aware that any +portion of the remainder has given rise to misconceptions among +intelligent and impartial critics, whom I do not here mention with +that praise which is their due, but who will find that their +suggestions have been attended to in the work itself. + +[*Footnote: The only addition, properly so called--and that only in +the method of proof--which I have made in the present edition, consists +of a new refutation of psychological idealism, and a strict +demonstration--the only one possible, as I believe--of the objective +reality of external intuition. However harmless idealism may be +considered--although in reality it is not so--in regard to the +essential ends of metaphysics, it must still remain a scandal to +philosophy and to the general human reason to be obliged to assume, +as an article of mere belief, the existence of things external to +ourselves (from which, yet, we derive the whole material of +cognition for the internal sense), and not to be able to oppose a +satisfactory proof to any one who may call it in question. As there +is some obscurity of expression in the demonstration as it stands in +the text, I propose to alter the passage in question as follows: +"But this permanent cannot be an intuition in me. For all the +determining grounds of my existence which can be found in me are +representations and, as such, do themselves require a permanent, +distinct from them, which may determine my existence in relation to +their changes, that is, my existence in time, wherein they change." +It may, probably, be urged in opposition to this proof that, after +all, I am only conscious immediately of that which is in me, that is, +of my representation of external things, and that, consequently, it +must always remain uncertain whether anything corresponding to this +representation does or does not exist externally to me. But I am +conscious, through internal experience, of my existence in time +(consequently, also, of the determinability of the former in the +latter), and that is more than the simple consciousness of my +representation. It is, in fact, the same as the empirical +consciousness of my existence, which can only be determined in +relation to something, which, while connected with my existence, is +external to me. This consciousness of my existence in time is, +therefore, identical with the consciousness of a relation to something +external to me, and it is, therefore, experience, not fiction, +sense, not imagination, which inseparably connects the external with +my internal sense. For the external sense is, in itself, the +relation of intuition to something real, external to me; and the +reality of this something, as opposed to the mere imagination of it, +rests solely on its inseparable connection with internal experience +as the condition of its possibility. If with the intellectual +consciousness of my existence, in the representation: I am, which +accompanies all my judgements, and all the operations of my +understanding, I could, at the same time, connect a determination of +my existence by intellectual intuition, then the consciousness of a +relation to something external to me would not be necessary. But the +internal intuition in which alone my existence can be determined, +though preceded by that purely intellectual consciousness, is itself +sensible and attached to the condition of time. Hence this +determination of my existence, and consequently my internal experience +itself, must depend on something permanent which is not in me, which +can be, therefore, only in something external to me, to which I must +look upon myself as being related. Thus the reality of the external +sense is necessarily connected with that of the internal, in order +to the possibility of experience in general; that is, I am just as +certainly conscious that there are things external to me related to +my sense as I am that I myself exist as determined in time. But in +order to ascertain to what given intuitions objects, external me, +really correspond, in other words, what intuitions belong to the +external sense and not to imagination, I must have recourse, in +every particular case, to those rules according to which experience +in general (even internal experience) is distinguished from +imagination, and which are always based on the proposition that +there really is an external experience. We may add the remark that +the representation of something permanent in existence, is not the +same thing as the permanent representation; for a representation may +be very variable and changing--as all our representations, even that +of matter, are--and yet refer to something permanent, which must, +therefore, be distinct from all my representations and external to +me, the existence of which is necessarily included in the determination +of my own existence, and with it constitutes one experience--an +experience which would not even be possible internally, if it were +not also at the same time, in part, external. To the question How? +we are no more able to reply, than we are, in general, to think the +stationary in time, the coexistence of which with the variable, +produces the conception of change.] + +In attempting to render the exposition of my views as intelligible +as possible, I have been compelled to leave out or abridge various +passages which were not essential to the completeness of the work, +but which many readers might consider useful in other respects, and +might be unwilling to miss. This trifling loss, which could not be +avoided without swelling the book beyond due limits, may be +supplied, at the pleasure of the reader, by a comparison with the +first edition, and will, I hope, be more than compensated for by the +greater clearness of the exposition as it now stands. + +I have observed, with pleasure and thankfulness, in the pages of +various reviews and treatises, that the spirit of profound and +thorough investigation is not extinct in Germany, though it may have +been overborne and silenced for a time by the fashionable tone of a +licence in thinking, which gives itself the airs of genius, and that +the difficulties which beset the paths of criticism have not prevented +energetic and acute thinkers from making themselves masters of the +science of pure reason to which these paths conduct--a science which +is not popular, but scholastic in its character, and which alone can +hope for a lasting existence or possess an abiding value. To these +deserving men, who so happily combine profundity of view with a talent +for lucid exposition--a talent which I myself am not conscious of +possessing--I leave the task of removing any obscurity which may still +adhere to the statement of my doctrines. For, in this case, the danger +is not that of being refuted, but of being misunderstood. For my own +part, I must henceforward abstain from controversy, although I shall +carefully attend to all suggestions, whether from friends or +adversaries, which may be of use in the future elaboration of the +system of this propaedeutic. As, during these labours, I have advanced +pretty far in years this month I reach my sixty-fourth year--it will +be necessary for me to economize time, if I am to carry out my plan +of elaborating the metaphysics of nature as well as of morals, in +confirmation of the correctness of the principles established in +this Critique of Pure Reason, both speculative and practical; and I +must, therefore, leave the task of clearing up the obscurities of +the present work--inevitable, perhaps, at the outset--as well as, +the defence of the whole, to those deserving men, who have made my +system their own. A philosophical system cannot come forward armed +at all points like a mathematical treatise, and hence it may be +quite possible to take objection to particular passages, while the +organic structure of the system, considered as a unity, has no +danger to apprehend. But few possess the ability, and still fewer +the inclination, to take a comprehensive view of a new system. By +confining the view to particular passages, taking these out of their +connection and comparing them with one another, it is easy to pick +out apparent contradictions, especially in a work written with any +freedom of style. These contradictions place the work in an unfavourable +light in the eyes of those who rely on the judgement of others, but +are easily reconciled by those who have mastered the idea of the whole. +If a theory possesses stability in itself, the action and reaction +which seemed at first to threaten its existence serve only, in the +course of time, to smooth down any superficial roughness or +inequality, and--if men of insight, impartiality, and truly popular +gifts, turn their attention to it--to secure to it, in a short time, +the requisite elegance also. + + + +Konigsberg, April 1787. +INTRODUCTION + + + + +I. Of the difference between Pure and Empirical Knowledge + +That all our knowledge begins with experience there can be no doubt. +For how is it possible that the faculty of cognition should be +awakened into exercise otherwise than by means of objects which affect +our senses, and partly of themselves produce representations, partly +rouse our powers of understanding into activity, to compare to +connect, or to separate these, and so to convert the raw material of +our sensuous impressions into a knowledge of objects, which is +called experience? In respect of time, therefore, no knowledge of ours +is antecedent to experience, but begins with it. + +But, though all our knowledge begins with experience, it by no means +follows that all arises out of experience. For, on the contrary, it +is quite possible that our empirical knowledge is a compound of that +which we receive through impressions, and that which the faculty of +cognition supplies from itself (sensuous impressions giving merely +the occasion), an addition which we cannot distinguish from the original +element given by sense, till long practice has made us attentive to, +and skilful in separating it. It is, therefore, a question which +requires close investigation, and not to be answered at first sight, +whether there exists a knowledge altogether independent of experience, +and even of all sensuous impressions? Knowledge of this kind is called +a priori, in contradistinction to empirical knowledge, which has its +sources a posteriori, that is, in experience. + +But the expression, "a priori," is not as yet definite enough +adequately to indicate the whole meaning of the question above +started. For, in speaking of knowledge which has its sources in +experience, we are wont to say, that this or that may be known a +priori, because we do not derive this knowledge immediately from +experience, but from a general rule, which, however, we have itself +borrowed from experience. Thus, if a man undermined his house, we say, +"he might know a priori that it would have fallen;" that is, he needed +not to have waited for the experience that it did actually fall. But +still, a priori, he could not know even this much. For, that bodies +are heavy, and, consequently, that they fall when their supports are +taken away, must have been known to him previously, by means of +experience. + +By the term "knowledge a priori," therefore, we shall in the +sequel understand, not such as is independent of this or that kind +of experience, but such as is absolutely so of all experience. Opposed +to this is empirical knowledge, or that which is possible only a +posteriori, that is, through experience. Knowledge a priori is +either pure or impure. Pure knowledge a priori is that with which no +empirical element is mixed up. For example, the proposition, "Every +change has a cause," is a proposition a priori, but impure, because +change is a conception which can only be derived from experience. + + + +II. The Human Intellect, even in an Unphilosophical State, + is in Possession of Certain Cognitions "a priori". + +The question now is as to a criterion, by which we may securely +distinguish a pure from an empirical cognition. Experience no doubt +teaches us that this or that object is constituted in such and such +a manner, but not that it could not possibly exist otherwise. Now, +in the first place, if we have a proposition which contains the idea +of necessity in its very conception, it is a if, moreover, it is not +derived from any other proposition, unless from one equally +involving the idea of necessity, it is absolutely priori. Secondly, +an empirical judgement never exhibits strict and absolute, but only +assumed and comparative universality (by induction); therefore, the +most we can say is--so far as we have hitherto observed, there is no +exception to this or that rule. If, on the other hand, a judgement +carries with it strict and absolute universality, that is, admits of +no possible exception, it is not derived from experience, but is valid +absolutely a priori. + +Empirical universality is, therefore, only an arbitrary extension of +validity, from that which may be predicated of a proposition valid +in most cases, to that which is asserted of a proposition which +holds good in all; as, for example, in the affirmation, "All bodies +are heavy." When, on the contrary, strict universality characterizes +a judgement, it necessarily indicates another peculiar source of +knowledge, namely, a faculty of cognition a priori. Necessity and +strict universality, therefore, are infallible tests for +distinguishing pure from empirical knowledge, and are inseparably +connected with each other. But as in the use of these criteria the +empirical limitation is sometimes more easily detected than the +contingency of the judgement, or the unlimited universality which we +attach to a judgement is often a more convincing proof than its +necessity, it may be advisable to use the criteria separately, each +being by itself infallible. + +Now, that in the sphere of human cognition we have judgements +which are necessary, and in the strictest sense universal, +consequently pure a priori, it will be an easy matter to show. If we +desire an example from the sciences, we need only take any proposition +in mathematics. If we cast our eyes upon the commonest operations of +the understanding, the proposition, "Every change must have a +cause," will amply serve our purpose. In the latter case, indeed, +the conception of a cause so plainly involves the conception of a +necessity of connection with an effect, and of a strict universality +of the law, that the very notion of a cause would entirely +disappear, were we to derive it, like Hume, from a frequent +association of what happens with that which precedes; and the habit +thence originating of connecting representations--the necessity +inherent in the judgement being therefore merely subjective. +Besides, without seeking for such examples of principles existing a +priori in cognition, we might easily show that such principles are +the indispensable basis of the possibility of experience itself, and +consequently prove their existence a priori. For whence could our +experience itself acquire certainty, if all the rules on which it +depends were themselves empirical, and consequently fortuitous? No +one, therefore, can admit the validity of the use of such rules as +first principles. But, for the present, we may content ourselves +with having established the fact, that we do possess and exercise a +faculty of pure a priori cognition; and, secondly, with having pointed +out the proper tests of such cognition, namely, universality and +necessity. + +Not only in judgements, however, but even in conceptions, is an a +priori origin manifest. For example, if we take away by degrees from +our conceptions of a body all that can be referred to mere sensuous +experience--colour, hardness or softness, weight, even +impenetrability--the body will then vanish; but the space which it +occupied still remains, and this it is utterly impossible to +annihilate in thought. Again, if we take away, in like manner, from +our empirical conception of any object, corporeal or incorporeal, +all properties which mere experience has taught us to connect with +it, still we cannot think away those through which we cogitate it as +substance, or adhering to substance, although our conception of +substance is more determined than that of an object. Compelled, +therefore, by that necessity with which the conception of substance +forces itself upon us, we must confess that it has its seat in our +faculty of cognition a priori. + + + +III. Philosophy stands in need of a Science which shall + Determine the Possibility, Principles, and Extent of + Human Knowledge "a priori" + +Of far more importance than all that has been above said, is the +consideration that certain of our cognitions rise completely above +the sphere of all possible experience, and by means of conceptions, +to which there exists in the whole extent of experience no +corresponding object, seem to extend the range of our judgements +beyond its bounds. And just in this transcendental or supersensible +sphere, where experience affords us neither instruction nor +guidance, lie the investigations of reason, which, on account of their +importance, we consider far preferable to, and as having a far more +elevated aim than, all that the understanding can achieve within the +sphere of sensuous phenomena. So high a value do we set upon these +investigations, that even at the risk of error, we persist in +following them out, and permit neither doubt nor disregard nor +indifference to restrain us from the pursuit. These unavoidable +problems of mere pure reason are God, freedom (of will), and +immortality. The science which, with all its preliminaries, has for +its especial object the solution of these problems is named +metaphysics--a science which is at the very outset dogmatical, that +is, it confidently takes upon itself the execution of this task +without any previous investigation of the ability or inability of +reason for such an undertaking. + +Now the safe ground of experience being thus abandoned, it seems +nevertheless natural that we should hesitate to erect a building +with the cognitions we possess, without knowing whence they come, +and on the strength of principles, the origin of which is +undiscovered. Instead of thus trying to build without a foundation, +it is rather to be expected that we should long ago have put the +question, how the understanding can arrive at these a priori +cognitions, and what is the extent, validity, and worth which they +may possess? We say, "This is natural enough," meaning by the word +natural, that which is consistent with a just and reasonable way of +thinking; but if we understand by the term, that which usually +happens, nothing indeed could be more natural and more +comprehensible than that this investigation should be left long +unattempted. For one part of our pure knowledge, the science of +mathematics, has been long firmly established, and thus leads us to +form flattering expectations with regard to others, though these may +be of quite a different nature. Besides, when we get beyond the bounds +of experience, we are of course safe from opposition in that +quarter; and the charm of widening the range of our knowledge is so +great that, unless we are brought to a standstill by some evident +contradiction, we hurry on undoubtingly in our course. This, +however, may be avoided, if we are sufficiently cautious in the +construction of our fictions, which are not the less fictions on +that account. + +Mathematical science affords us a brilliant example, how far, +independently of all experience, we may carry our a priori +knowledge. It is true that the mathematician occupies himself with +objects and cognitions only in so far as they can be represented by +means of intuition. But this circumstance is easily overlooked, +because the said intuition can itself be given a priori, and therefore +is hardly to be distinguished from a mere pure conception. Deceived +by such a proof of the power of reason, we can perceive no limits to +the extension of our knowledge. The light dove cleaving in free flight +the thin air, whose resistance it feels, might imagine that her +movements would be far more free and rapid in airless space. Just in +the same way did Plato, abandoning the world of sense because of the +narrow limits it sets to the understanding, venture upon the wings +of ideas beyond it, into the void space of pure intellect. He did +not reflect that he made no real progress by all his efforts; for he +met with no resistance which might serve him for a support, as it +were, whereon to rest, and on which he might apply his powers, in +order to let the intellect acquire momentum for its progress. It is, +indeed, the common fate of human reason in speculation, to finish +the imposing edifice of thought as rapidly as possible, and then for +the first time to begin to examine whether the foundation is a solid +one or no. Arrived at this point, all sorts of excuses are sought +after, in order to console us for its want of stability, or rather, +indeed, to enable Us to dispense altogether with so late and dangerous +an investigation. But what frees us during the process of building +from all apprehension or suspicion, and flatters us into the belief +of its solidity, is this. A great part, perhaps the greatest part, +of the business of our reason consists in the analysation of the +conceptions which we already possess of objects. By this means we gain +a multitude of cognitions, which although really nothing more than +elucidations or explanations of that which (though in a confused +manner) was already thought in our conceptions, are, at least in +respect of their form, prized as new introspections; whilst, so far +as regards their matter or content, we have really made no addition +to our conceptions, but only disinvolved them. But as this process +does furnish a real priori knowledge, which has a sure progress and +useful results, reason, deceived by this, slips in, without being +itself aware of it, assertions of a quite different kind; in which, +to given conceptions it adds others, a priori indeed, but entirely +foreign to them, without our knowing how it arrives at these, and, +indeed, without such a question ever suggesting itself. I shall +therefore at once proceed to examine the difference between these +two modes of knowledge. + + + +IV. Of the Difference Between Analytical and Synthetical Judgements. + +In all judgements wherein the relation of a subject to the predicate +is cogitated (I mention affirmative judgements only here; the +application to negative will be very easy), this relation is +possible in two different ways. Either the predicate B belongs to +the subject A, as somewhat which is contained (though covertly) in +the conception A; or the predicate B lies completely out of the conception +A, although it stands in connection with it. In the first instance, +I term the judgement analytical, in the second, synthetical. +Analytical judgements (affirmative) are therefore those in which the +connection of the predicate with the subject is cogitated through +identity; those in which this connection is cogitated without +identity, are called synthetical judgements. The former may be +called explicative, the latter augmentative judgements; because the +former add in the predicate nothing to the conception of the +subject, but only analyse it into its constituent conceptions, which +were thought already in the subject, although in a confused manner; +the latter add to our conceptions of the subject a predicate which +was not contained in it, and which no analysis could ever have +discovered therein. For example, when I say, "All bodies are +extended," this is an analytical judgement. For I need not go beyond +the conception of body in order to find extension connected with it, +but merely analyse the conception, that is, become conscious of the +manifold properties which I think in that conception, in order to +discover this predicate in it: it is therefore an analytical +judgement. On the other hand, when I say, "All bodies are heavy," +the predicate is something totally different from that which I think +in the mere conception of a body. By the addition of such a predicate, +therefore, it becomes a synthetical judgement. + +Judgements of experience, as such, are always synthetical. For it +would be absurd to think of grounding an analytical judgement on +experience, because in forming such a judgement I need not go out of +the sphere of my conceptions, and therefore recourse to the +testimony of experience is quite unnecessary. That "bodies are +extended" is not an empirical judgement, but a proposition which +stands firm a priori. For before addressing myself to experience, I +already have in my conception all the requisite conditions for the +judgement, and I have only to extract the predicate from the +conception, according to the principle of contradiction, and thereby +at the same time become conscious of the necessity of the judgement, +a necessity which I could never learn from experience. On the other +hand, though at first I do not at all include the predicate of +weight in my conception of body in general, that conception still +indicates an object of experience, a part of the totality of +experience, to which I can still add other parts; and this I do when +I recognize by observation that bodies are heavy. I can cognize +beforehand by analysis the conception of body through the +characteristics of extension, impenetrability, shape, etc., all +which are cogitated in this conception. But now I extend my knowledge, +and looking back on experience from which I had derived this +conception of body, I find weight at all times connected with the +above characteristics, and therefore I synthetically add to my +conceptions this as a predicate, and say, "All bodies are heavy." Thus +it is experience upon which rests the possibility of the synthesis +of the predicate of weight with the conception of body, because both +conceptions, although the one is not contained in the other, still +belong to one another (only contingently, however), as parts of a +whole, namely, of experience, which is itself a synthesis of +intuitions. + +But to synthetical judgements a priori, such aid is entirely +wanting. If I go out of and beyond the conception A, in order to +recognize another B as connected with it, what foundation have I to +rest on, whereby to render the synthesis possible? I have here no +longer the advantage of looking out in the sphere of experience for +what I want. Let us take, for example, the proposition, "Everything +that happens has a cause." In the conception of "something that +happens," I indeed think an existence which a certain time +antecedes, and from this I can derive analytical judgements. But the +conception of a cause lies quite out of the above conception, and +indicates something entirely different from "that which happens," +and is consequently not contained in that conception. How then am I +able to assert concerning the general conception--"that which +happens"--something entirely different from that conception, and to +recognize the conception of cause although not contained in it, yet +as belonging to it, and even necessarily? what is here the unknown += X, upon which the understanding rests when it believes it has found, +out of the conception A a foreign predicate B, which it nevertheless +considers to be connected with it? It cannot be experience, because +the principle adduced annexes the two representations, cause and +effect, to the representation existence, not only with universality, +which experience cannot give, but also with the expression of +necessity, therefore completely a priori and from pure conceptions. +Upon such synthetical, that is augmentative propositions, depends +the whole aim of our speculative knowledge a priori; for although +analytical judgements are indeed highly important and necessary, +they are so, only to arrive at that clearness of conceptions which +is requisite for a sure and extended synthesis, and this alone is a +real acquisition. + + + +V. In all Theoretical Sciences of Reason, Synthetical Judgements +"a priori" are contained as Principles. + +1. Mathematical judgements are always synthetical. Hitherto this +fact, though incontestably true and very important in its +consequences, seems to have escaped the analysts of the human mind, +nay, to be in complete opposition to all their conjectures. For as +it was found that mathematical conclusions all proceed according to +the principle of contradiction (which the nature of every apodeictic +certainty requires), people became persuaded that the fundamental +principles of the science also were recognized and admitted in the +same way. But the notion is fallacious; for although a synthetical +proposition can certainly be discerned by means of the principle of +contradiction, this is possible only when another synthetical +proposition precedes, from which the latter is deduced, but never +of itself. + +Before all, be it observed, that proper mathematical propositions +are always judgements a priori, and not empirical, because they +carry along with them the conception of necessity, which cannot be +given by experience. If this be demurred to, it matters not; I will +then limit my assertion to pure mathematics, the very conception of +which implies that it consists of knowledge altogether non-empirical +and a priori. + +We might, indeed at first suppose that the proposition 7 + 5 = 12 is +a merely analytical proposition, following (according to the principle +of contradiction) from the conception of a sum of seven and five. +But if we regard it more narrowly, we find that our conception of +the sum of seven and five contains nothing more than the uniting of +both sums into one, whereby it cannot at all be cogitated what this +single number is which embraces both. The conception of twelve is by +no means obtained by merely cogitating the union of seven and five; +and we may analyse our conception of such a possible sum as long as +we will, still we shall never discover in it the notion of twelve. +We must go beyond these conceptions, and have recourse to an intuition +which corresponds to one of the two--our five fingers, for example, +or like Segner in his Arithmetic five points, and so by degrees, add +the units contained in the five given in the intuition, to the +conception of seven. For I first take the number 7, and, for the +conception of 5 calling in the aid of the fingers of my hand as +objects of intuition, I add the units, which I before took together +to make up the number 5, gradually now by means of the material image +my hand, to the number 7, and by this process, I at length see the +number 12 arise. That 7 should be added to 5, I have certainly +cogitated in my conception of a sum = 7 + 5, but not that this sum +was equal to 12. Arithmetical propositions are therefore always +synthetical, of which we may become more clearly convinced by trying +large numbers. For it will thus become quite evident that, turn and +twist our conceptions as we may, it is impossible, without having +recourse to intuition, to arrive at the sum total or product by +means of the mere analysis of our conceptions. Just as little is any +principle of pure geometry analytical. "A straight line between two +points is the shortest," is a synthetical proposition. For my +conception of straight contains no notion of quantity, but is merely +qualitative. The conception of the shortest is therefore fore wholly +an addition, and by no analysis can it be extracted from our +conception of a straight line. Intuition must therefore here lend +its aid, by means of which, and thus only, our synthesis is possible. + +Some few principles preposited by geometricians are, indeed, +really analytical, and depend on the principle of contradiction. +They serve, however, like identical propositions, as links in the +chain of method, not as principles--for example, a = a, the whole is +equal to itself, or (a+b) > a, the whole is greater than its part. +And yet even these principles themselves, though they derive their +validity from pure conceptions, are only admitted in mathematics +because they can be presented in intuition. What causes us here +commonly to believe that the predicate of such apodeictic judgements +is already contained in our conception, and that the judgement is +therefore analytical, is merely the equivocal nature of the +expression. We must join in thought a certain predicate to a given +conception, and this necessity cleaves already to the conception. +But the question is, not what we must join in thought to the given +conception, but what we really think therein, though only obscurely, +and then it becomes manifest that the predicate pertains to these +conceptions, necessarily indeed, yet not as thought in the +conception itself, but by virtue of an intuition, which must be +added to the conception. + +2. The science of natural philosophy (physics) contains in itself +synthetical judgements a priori, as principles. I shall adduce two +propositions. For instance, the proposition, "In all changes of the +material world, the quantity of matter remains unchanged"; or, that, +"In all communication of motion, action and reaction must always be +equal." In both of these, not only is the necessity, and therefore +their origin a priori clear, but also that they are synthetical +propositions. For in the conception of matter, I do not cogitate its +permanency, but merely its presence in space, which it fills. I +therefore really go out of and beyond the conception of matter, in +order to think on to it something a priori, which I did not think in +it. The proposition is therefore not analytical, but synthetical, +and nevertheless conceived a priori; and so it is with regard to the +other propositions of the pure part of natural philosophy. + +3. As to metaphysics, even if we look upon it merely as an attempted +science, yet, from the nature of human reason, an indispensable one, +we find that it must contain synthetical propositions a priori. It +is not merely the duty of metaphysics to dissect, and thereby +analytically to illustrate the conceptions which we form a priori of +things; but we seek to widen the range of our a priori knowledge. +For this purpose, we must avail ourselves of such principles as add +something to the original conception--something not identical with, +nor contained in it, and by means of synthetical judgements a +priori, leave far behind us the limits of experience; for example, +in the proposition, "the world must have a beginning," and such +like. Thus metaphysics, according to the proper aim of the science, +consists merely of synthetical propositions a priori. + + + +VI. The Universal Problem of Pure Reason. + +It is extremely advantageous to be able to bring a number of +investigations under the formula of a single problem. For in this +manner, we not only facilitate our own labour, inasmuch as we define +it clearly to ourselves, but also render it more easy for others to +decide whether we have done justice to our undertaking. The proper +problem of pure reason, then, is contained in the question: "How are +synthetical judgements a priori possible?" + +That metaphysical science has hitherto remained in so vacillating +a state of uncertainty and contradiction, is only to be attributed +to the fact that this great problem, and perhaps even the difference +between analytical and synthetical judgements, did not sooner +suggest itself to philosophers. Upon the solution of this problem, +or upon sufficient proof of the impossibility of synthetical knowledge +a priori, depends the existence or downfall of the science of +metaphysics. Among philosophers, David Hume came the nearest of all +to this problem; yet it never acquired in his mind sufficient +precision, nor did he regard the question in its universality. On +the contrary, he stopped short at the synthetical proposition of the +connection of an effect with its cause (principium causalitatis), +insisting that such proposition a priori was impossible. According +to his conclusions, then, all that we term metaphysical science is +a mere delusion, arising from the fancied insight of reason into that +which is in truth borrowed from experience, and to which habit has +given the appearance of necessity. Against this assertion, destructive +to all pure philosophy, he would have been guarded, had he had our +problem before his eyes in its universality. For he would then have +perceived that, according to his own argument, there likewise could +not be any pure mathematical science, which assuredly cannot exist +without synthetical propositions a priori--an absurdity from which +his good understanding must have saved him. + +In the solution of the above problem is at the same time +comprehended the possibility of the use of pure reason in the +foundation and construction of all sciences which contain +theoretical knowledge a priori of objects, that is to say, the +answer to the following questions: + +How is pure mathematical science possible? + +How is pure natural science possible? + +Respecting these sciences, as they do certainly exist, it may with +propriety be asked, how they are possible?--for that they must be +possible is shown by the fact of their really existing.* But as to +metaphysics, the miserable progress it has hitherto made, and the fact +that of no one system yet brought forward, far as regards its true +aim, can it be said that this science really exists, leaves any one +at liberty to doubt with reason the very possibility of its existence. + +[*Footnote: As to the existence of pure natural science, or physics, +perhaps many may still express doubts. But we have only to look at +the different propositions which are commonly treated of at the +commencement of proper (empirical) physical science--those, for +example, relating to the permanence of the same quantity of matter, +the vis inertiae, the equality of action and reaction, etc.--to be +soon convinced that they form a science of pure physics (physica pura, +or rationalis), which well deserves to be separately exposed as a +special science, in its whole extent, whether that be great or +confined.] + +Yet, in a certain sense, this kind of knowledge must +unquestionably be looked upon as given; in other words, metaphysics +must be considered as really existing, if not as a science, +nevertheless as a natural disposition of the human mind (metaphysica +naturalis). For human reason, without any instigations imputable to +the mere vanity of great knowledge, unceasingly progresses, urged on +by its own feeling of need, towards such questions as cannot be +answered by any empirical application of reason, or principles derived +therefrom; and so there has ever really existed in every man some +system of metaphysics. It will always exist, so soon as reason +awakes to the exercise of its power of speculation. And now the +question arises: "How is metaphysics, as a natural disposition, +possible?" In other words, how, from the nature of universal human +reason, do those questions arise which pure reason proposes to itself, +and which it is impelled by its own feeling of need to answer as +well as it can? + +But as in all the attempts hitherto made to answer the questions +which reason is prompted by its very nature to propose to itself, +for example, whether the world had a beginning, or has existed from +eternity, it has always met with unavoidable contradictions, we must +not rest satisfied with the mere natural disposition of the mind to +metaphysics, that is, with the existence of the faculty of pure +reason, whence, indeed, some sort of metaphysical system always +arises; but it must be possible to arrive at certainty in regard to +the question whether we know or do not know the things of which +metaphysics treats. We must be able to arrive at a decision on the +subjects of its questions, or on the ability or inability of reason +to form any judgement respecting them; and therefore either to extend +with confidence the bounds of our pure reason, or to set strictly +defined and safe limits to its action. This last question, which +arises out of the above universal problem, would properly run thus: +"How is metaphysics possible as a science?" + +Thus, the critique of reason leads at last, naturally and +necessarily, to science; and, on the other hand, the dogmatical use +of reason without criticism leads to groundless assertions, against +which others equally specious can always be set, thus ending unavoidably +in scepticism. + +Besides, this science cannot be of great and formidable prolixity, +because it has not to do with objects of reason, the variety of +which is inexhaustible, but merely with Reason herself and her +problems; problems which arise out of her own bosom, and are not +proposed to her by the nature of outward things, but by her own +nature. And when once Reason has previously become able completely +to understand her own power in regard to objects which she meets +with in experience, it will be easy to determine securely the extent +and limits of her attempted application to objects beyond the confines +of experience. + +We may and must, therefore, regard the attempts hitherto made to +establish metaphysical science dogmatically as non-existent. For +what of analysis, that is, mere dissection of conceptions, is +contained in one or other, is not the aim of, but only a preparation +for metaphysics proper, which has for its object the extension, by +means of synthesis, of our a priori knowledge. And for this purpose, +mere analysis is of course useless, because it only shows what is +contained in these conceptions, but not how we arrive, a priori, at +them; and this it is her duty to show, in order to be able +afterwards to determine their valid use in regard to all objects of +experience, to all knowledge in general. But little self-denial, +indeed, is needed to give up these pretensions, seeing the undeniable, +and in the dogmatic mode of procedure, inevitable contradictions of +Reason with herself, have long since ruined the reputation of every +system of metaphysics that has appeared up to this time. It will +require more firmness to remain undeterred by difficulty from +within, and opposition from without, from endeavouring, by a method +quite opposed to all those hitherto followed, to further the growth +and fruitfulness of a science indispensable to human reason--a science +from which every branch it has borne may be cut away, but whose +roots remain indestructible. + + + +VII. Idea and Division of a Particular Science, under the + Name of a Critique of Pure Reason. + +From all that has been said, there results the idea of a +particular science, which may be called the Critique of Pure Reason. +For reason is the faculty which furnishes us with the principles of +knowledge a priori. Hence, pure reason is the faculty which contains +the principles of cognizing anything absolutely a priori. An organon +of pure reason would be a compendium of those principles according +to which alone all pure cognitions a priori can be obtained. The +completely extended application of such an organon would afford us +a system of pure reason. As this, however, is demanding a great deal, +and it is yet doubtful whether any extension of our knowledge be +here possible, or, if so, in what cases; we can regard a science of +the mere criticism of pure reason, its sources and limits, as the +propaedeutic to a system of pure reason. Such a science must not be +called a doctrine, but only a critique of pure reason; and its use, +in regard to speculation, would be only negative, not to enlarge the +bounds of, but to purify, our reason, and to shield it against +error--which alone is no little gain. I apply the term +transcendental to all knowledge which is not so much occupied with +objects as with the mode of our cognition of these objects, so far +as this mode of cognition is possible a priori. A system of such +conceptions would be called transcendental philosophy. But this, +again, is still beyond the bounds of our present essay. For as such +a science must contain a complete exposition not only of our +synthetical a priori, but of our analytical a priori knowledge, it +is of too wide a range for our present purpose, because we do not +require to carry our analysis any farther than is necessary to +understand, in their full extent, the principles of synthesis a +priori, with which alone we have to do. This investigation, which we +cannot properly call a doctrine, but only a transcendental critique, +because it aims not at the enlargement, but at the correction and +guidance, of our knowledge, and is to serve as a touchstone of the +worth or worthlessness of all knowledge a priori, is the sole object +of our present essay. Such a critique is consequently, as far as +possible, a preparation for an organon; and if this new organon should +be found to fail, at least for a canon of pure reason, according to +which the complete system of the philosophy of pure reason, whether +it extend or limit the bounds of that reason, might one day be set +forth both analytically and synthetically. For that this is +possible, nay, that such a system is not of so great extent as to +preclude the hope of its ever being completed, is evident. For we have +not here to do with the nature of outward objects, which is +infinite, but solely with the mind, which judges of the nature of +objects, and, again, with the mind only in respect of its cognition +a priori. And the object of our investigations, as it is not to be +sought without, but, altogether within, ourselves, cannot remain +concealed, and in all probability is limited enough to be completely +surveyed and fairly estimated, according to its worth or +worthlessness. Still less let the reader here expect a critique of +books and systems of pure reason; our present object is exclusively +a critique of the faculty of pure reason itself. Only when we make +this critique our foundation, do we possess a pure touchstone for +estimating the philosophical value of ancient and modern writings on +this subject; and without this criterion, the incompetent historian +or judge decides upon and corrects the groundless assertions of others +with his own, which have themselves just as little foundation. + +Transcendental philosophy is the idea of a science, for which the +Critique of Pure Reason must sketch the whole plan +architectonically, that is, from principles, with a full guarantee +for the validity and stability of all the parts which enter into the +building. It is the system of all the principles of pure reason. If +this Critique itself does not assume the title of transcendental +philosophy, it is only because, to be a complete system, it ought to +contain a full analysis of all human knowledge a priori. Our +critique must, indeed, lay before us a complete enumeration of all +the radical conceptions which constitute the said pure knowledge. But +from the complete analysis of these conceptions themselves, as also +from a complete investigation of those derived from them, it abstains +with reason; partly because it would be deviating from the end in view +to occupy itself with this analysis, since this process is not +attended with the difficulty and insecurity to be found in the +synthesis, to which our critique is entirely devoted, and partly +because it would be inconsistent with the unity of our plan to +burden this essay with the vindication of the completeness of such +an analysis and deduction, with which, after all, we have at present +nothing to do. This completeness of the analysis of these radical +conceptions, as well as of the deduction from the conceptions a priori +which may be given by the analysis, we can, however, easily attain, +provided only that we are in possession of all these radical +conceptions, which are to serve as principles of the synthesis, and +that in respect of this main purpose nothing is wanting. + +To the Critique of Pure Reason, therefore, belongs all that +constitutes transcendental philosophy; and it is the complete idea +of transcendental philosophy, but still not the science itself; +because it only proceeds so far with the analysis as is necessary to +the power of judging completely of our synthetical knowledge a priori. + +The principal thing we must attend to, in the division of the +parts of a science like this, is that no conceptions must enter it +which contain aught empirical; in other words, that the knowledge a +priori must be completely pure. Hence, although the highest principles +and fundamental conceptions of morality are certainly cognitions a +priori, yet they do not belong to transcendental philosophy; +because, though they certainly do not lay the conceptions of pain, +pleasure, desires, inclinations, etc. (which are all of empirical +origin), at the foundation of its precepts, yet still into the +conception of duty--as an obstacle to be overcome, or as an incitement +which should not be made into a motive--these empirical conceptions +must necessarily enter, in the construction of a system of pure +morality. Transcendental philosophy is consequently a philosophy of +the pure and merely speculative reason. For all that is practical, +so far as it contains motives, relates to feelings, and these belong +to empirical sources of cognition. + +If we wish to divide this science from the universal point of view +of a science in general, it ought to comprehend, first, a Doctrine +of the Elements, and, secondly, a Doctrine of the Method of pure +reason. Each of these main divisions will have its subdivisions, the +separate reasons for which we cannot here particularize. Only so +much seems necessary, by way of introduction of premonition, that +there are two sources of human knowledge (which probably spring from +a common, but to us unknown root), namely, sense and understanding. +By the former, objects are given to us; by the latter, thought. So +far as the faculty of sense may contain representations a priori, which +form the conditions under which objects are given, in so far it +belongs to transcendental philosophy. The transcendental doctrine of +sense must form the first part of our science of elements, because +the conditions under which alone the objects of human knowledge are +given must precede those under which they are thought. + + + + +I. TRANSCENDENTAL DOCTRINE OF ELEMENTS. + +FIRST PART. TRANSCENDENTAL AESTHETIC. + +SS I. Introductory. + +In whatsoever mode, or by whatsoever means, our knowledge may relate +to objects, it is at least quite clear that the only manner in which +it immediately relates to them is by means of an intuition. To this +as the indispensable groundwork, all thought points. But an intuition +can take place only in so far as the object is given to us. This, again, +is only possible, to man at least, on condition that the object affect +the mind in a certain manner. The capacity for receiving +representations (receptivity) through the mode in which we are +affected by objects, objects, is called sensibility. By means of +sensibility, therefore, objects are given to us, and it alone +furnishes us with intuitions; by the understanding they are thought, +and from it arise conceptions. But an thought must directly, or +indirectly, by means of certain signs, relate ultimately to +intuitions; consequently, with us, to sensibility, because in no other +way can an object be given to us. + +The effect of an object upon the faculty of representation, so far +as we are affected by the said object, is sensation. That sort of +intuition which relates to an object by means of sensation is called +an empirical intuition. The undetermined object of an empirical +intuition is called phenomenon. That which in the phenomenon +corresponds to the sensation, I term its matter; but that which +effects that the content of the phenomenon can be arranged under +certain relations, I call its form. But that in which our sensations +are merely arranged, and by which they are susceptible of assuming +a certain form, cannot be itself sensation. It is, then, the matter +of all phenomena that is given to us a posteriori; the form must lie +ready a priori for them in the mind, and consequently can be +regarded separately from all sensation. + +I call all representations pure, in the transcendental meaning of +the word, wherein nothing is met with that belongs to sensation. And +accordingly we find existing in the mind a priori, the pure form of +sensuous intuitions in general, in which all the manifold content of +the phenomenal world is arranged and viewed under certain relations. +This pure form of sensibility I shall call pure intuition. Thus, if +I take away from our representation of a body all that the +understanding thinks as belonging to it, as substance, force, +divisibility, etc., and also whatever belongs to sensation, as +impenetrability, hardness, colour, etc.; yet there is still +something left us from this empirical intuition, namely, extension +and shape. These belong to pure intuition, which exists a priori in +the mind, as a mere form of sensibility, and without any real object +of the senses or any sensation. + +The science of all the principles of sensibility a priori, I call +transcendental aesthetic.* There must, then, be such a science forming +the first part of the transcendental doctrine of elements, in +contradistinction to that part which contains the principles of pure +thought, and which is called transcendental logic. + +[Footnote: The Germans are the only people who at present use this +word to indicate what others call the critique of taste. At the foundation +of this term lies the disappointed hope, which the eminent analyst, +Baumgarten, conceived, of subjecting the criticism of the beautiful +to principles of reason, and so of elevating its rules into a science. +But his endeavours were vain. For the said rules or criteria are, in +respect to their chief sources, merely empirical, consequently never +can serve as determinate laws a priori, by which our judgement in +matters of taste is to be directed. It is rather our judgement which +forms the proper test as to the correctness of the principles. On this +account it is advisable to give up the use of the term as +designating the critique of taste, and to apply it solely to that +doctrine, which is true science--the science of the laws of +sensibility--and thus come nearer to the language and the sense of +the ancients in their well-known division of the objects of cognition +into aiotheta kai noeta, or to share it with speculative philosophy, +and employ it partly in a transcendental, partly in a psychological +signification.] + +In the science of transcendental aesthetic accordingly, we shall +first isolate sensibility or the sensuous faculty, by separating +from it all that is annexed to its perceptions by the conceptions of +understanding, so that nothing be left but empirical intuition. In +the next place we shall take away from this intuition all that belongs +to sensation, so that nothing may remain but pure intuition, and the +mere form of phenomena, which is all that the sensibility can afford +a priori. From this investigation it will be found that there are two +pure forms of sensuous intuition, as principles of knowledge a priori, +namely, space and time. To the consideration of these we shall now +proceed. + + + +SECTION I. Of Space. + +SS 2. Metaphysical Exposition of this Conception. + +By means of the external sense (a property of the mind), we +represent to ourselves objects as without us, and these all in +space. Herein alone are their shape, dimensions, and relations to each +other determined or determinable. The internal sense, by means of +which the mind contemplates itself or its internal state, gives, +indeed, no intuition of the soul as an object; yet there is +nevertheless a determinate form, under which alone the contemplation +of our internal state is possible, so that all which relates to the +inward determinations of the mind is represented in relations of time. +Of time we cannot have any external intuition, any more than we can +have an internal intuition of space. What then are time and space? +Are they real existences? Or, are they merely relations or +determinations of things, such, however, as would equally belong to +these things in themselves, though they should never become objects +of intuition; or, are they such as belong only to the form of +intuition, and consequently to the subjective constitution of the +mind, without which these predicates of time and space could not be +attached to any object? In order to become informed on these points, +we shall first give an exposition of the conception of space. By +exposition, I mean the clear, though not detailed, representation of +that which belongs to a conception; and an exposition is +metaphysical when it contains that which represents the conception +as given a priori. + +1. Space is not a conception which has been derived from outward +experiences. For, in order that certain sensations may relate to +something without me (that is, to something which occupies a different +part of space from that in which I am); in like manner, in order +that I may represent them not merely as without, of, and near to +each other, but also in separate places, the representation of space +must already exist as a foundation. Consequently, the representation +of space cannot be borrowed from the relations of external phenomena +through experience; but, on the contrary, this external experience +is itself only possible through the said antecedent representation. + +2. Space then is a necessary representation a priori, which serves +for the foundation of all external intuitions. We never can imagine +or make a representation to ourselves of the non-existence of space, +though we may easily enough think that no objects are found in it. +It must, therefore, be considered as the condition of the +possibility of phenomena, and by no means as a determination dependent +on them, and is a representation a priori, which necessarily +supplies the basis for external phenomena. + +3. Space is no discursive, or as we say, general conception of the +relations of things, but a pure intuition. For, in the first place, +we can only represent to ourselves one space, and, when we talk of +divers spaces, we mean only parts of one and the same space. Moreover, +these parts cannot antecede this one all-embracing space, as the +component parts from which the aggregate can be made up, but can be +cogitated only as existing in it. Space is essentially one, and +multiplicity in it, consequently the general notion of spaces, of this +or that space, depends solely upon limitations. Hence it follows +that an a priori intuition (which is not empirical) lies at the root +of all our conceptions of space. Thus, moreover, the principles of +geometry--for example, that "in a triangle, two sides together are +greater than the third," are never deduced from general conceptions +of line and triangle, but from intuition, and this a priori, with +apodeictic certainty. + +4. Space is represented as an infinite given quantity. Now every +conception must indeed be considered as a representation which is +contained in an infinite multitude of different possible +representations, which, therefore, comprises these under itself; but +no conception, as such, can be so conceived, as if it contained within +itself an infinite multitude of representations. Nevertheless, space +is so conceived of, for all parts of space are equally capable of +being produced to infinity. Consequently, the original +representation of space is an intuition a priori, and not a +conception. + + + +SS 3. Transcendental Exposition of the Conception of Space. + +By a transcendental exposition, I mean the explanation of a +conception, as a principle, whence can be discerned the possibility +of other synthetical a priori cognitions. For this purpose, it is +requisite, firstly, that such cognitions do really flow from the given +conception; and, secondly, that the said cognitions are only +possible under the presupposition of a given mode of explaining this +conception. + +Geometry is a science which determines the properties of space +synthetically, and yet a priori. What, then, must be our +representation of space, in order that such a cognition of it may be +possible? It must be originally intuition, for from a mere conception, +no propositions can be deduced which go out beyond the conception, +and yet this happens in geometry. (Introd. V.) But this intuition must +be found in the mind a priori, that is, before any perception of +objects, consequently must be pure, not empirical, intuition. For +geometrical principles are always apodeictic, that is, united with +the consciousness of their necessity, as: "Space has only three +dimensions." But propositions of this kind cannot be empirical +judgements, nor conclusions from them. (Introd. II.) Now, how can an +external intuition anterior to objects themselves, and in which our +conception of objects can be determined a priori, exist in the human +mind? Obviously not otherwise than in so far as it has its seat in +the subject only, as the formal capacity of the subject's being affected +by objects, and thereby of obtaining immediate representation, that +is, intuition; consequently, only as the form of the external sense +in general. + +Thus it is only by means of our explanation that the possibility +of geometry, as a synthetical science a priori, becomes +comprehensible. Every mode of explanation which does not show us +this possibility, although in appearance it may be similar to ours, +can with the utmost certainty be distinguished from it by these marks. + + + +SS 4. Conclusions from the foregoing Conceptions. + +(a) Space does not represent any property of objects as +things in themselves, nor does it represent them in their relations +to each other; in other words, space does not represent to us any +determination of objects such as attaches to the objects themselves, +and would remain, even though all subjective conditions of the +intuition were abstracted. For neither absolute nor relative +determinations of objects can be intuited prior to the existence of +the things to which they belong, and therefore not a priori. + +(b) Space is nothing else than the form of all phenomena of the +external sense, that is, the subjective condition of the +sensibility, under which alone external intuition is possible. Now, +because the receptivity or capacity of the subject to be affected by +objects necessarily antecedes all intuitions of these objects, it is +easily understood how the form of all phenomena can be given in the +mind previous to all actual perceptions, therefore a priori, and how +it, as a pure intuition, in which all objects must be determined, +can contain principles of the relations of these objects prior to +all experience. + +It is therefore from the human point of view only that we can +speak of space, extended objects, etc. If we depart from the +subjective condition, under which alone we can obtain external +intuition, or, in other words, by means of which we are affected by +objects, the representation of space has no meaning whatsoever. This +predicate is only applicable to things in so far as they appear to +us, that is, are objects of sensibility. The constant form of this +receptivity, which we call sensibility, is a necessary condition of +all relations in which objects can be intuited as existing without +us, and when abstraction of these objects is made, is a pure intuition, +to which we give the name of space. It is clear that we cannot make +the special conditions of sensibility into conditions of the possibility +of things, but only of the possibility of their existence as far as +they are phenomena. And so we may correctly say that space contains +all which can appear to us externally, but not all things considered +as things in themselves, be they intuited or not, or by whatsoever +subject one will. As to the intuitions of other thinking beings, we +cannot judge whether they are or are not bound by the same +conditions which limit our own intuition, and which for us are +universally valid. If we join the limitation of a judgement to the +conception of the subject, then the judgement will possess +unconditioned validity. For example, the proposition, "All objects +are beside each other in space," is valid only under the limitation +that these things are taken as objects of our sensuous intuition. But +if I join the condition to the conception and say, "All things, as +external phenomena, are beside each other in space," then the rule +is valid universally, and without any limitation. Our expositions, +consequently, teach the reality (i.e., the objective validity) of +space in regard of all which can be presented to us externally as +object, and at the same time also the ideality of space in regard to +objects when they are considered by means of reason as things in +themselves, that is, without reference to the constitution of our +sensibility. We maintain, therefore, the empirical reality of space +in regard to all possible external experience, although we must admit +its transcendental ideality; in other words, that it is nothing, so +soon as we withdraw the condition upon which the possibility of all +experience depends and look upon space as something that belongs to +things in themselves. + +But, with the exception of space, there is no representation, +subjective and referring to something external to us, which could +be called objective a priori. For there are no other subjective +representations from which we can deduce synthetical propositions a +priori, as we can from the intuition of space. (See SS 3.) +Therefore, to speak accurately, no ideality whatever belongs to these, +although they agree in this respect with the representation of +space, that they belong merely to the subjective nature of the mode +of sensuous perception; such a mode, for example, as that of sight, +of hearing, and of feeling, by means of the sensations of colour, +sound, and heat, but which, because they are only sensations and not +intuitions, do not of themselves give us the cognition of any +object, least of all, an a priori cognition. My purpose, in the +above remark, is merely this: to guard any one against illustrating +the asserted ideality of space by examples quite insufficient, for +example, by colour, taste, etc.; for these must be contemplated not +as properties of things, but only as changes in the subject, changes +which may be different in different men. For, in such a case, that +which is originally a mere phenomenon, a rose, for example, is taken +by the empirical understanding for a thing in itself, though to +every different eye, in respect of its colour, it may appear +different. On the contrary, the transcendental conception of phenomena +in space is a critical admonition, that, in general, nothing which +is intuited in space is a thing in itself, and that space is not a +form which belongs as a property to things; but that objects are quite +unknown to us in themselves, and what we call outward objects, are +nothing else but mere representations of our sensibility, whose form +is space, but whose real correlate, the thing in itself, is not +known by means of these representations, nor ever can be, but +respecting which, in experience, no inquiry is ever made. + + + + +SECTION II. Of Time. + +SS 5. Metaphysical Exposition of this Conception. + +1. Time is not an empirical conception. For neither coexistence +nor succession would be perceived by us, if the representation of time +did not exist as a foundation a priori. Without this presupposition +we could not represent to ourselves that things exist together at one +and the same time, or at different times, that is, contemporaneously, +or in succession. + +2. Time is a necessary representation, lying at the foundation of +all our intuitions. With regard to phenomena in general, we cannot +think away time from them, and represent them to ourselves as out of +and unconnected with time, but we can quite well represent to +ourselves time void of phenomena. Time is therefore given a priori. +In it alone is all reality of phenomena possible. These may all be +annihilated in thought, but time itself, as the universal condition +of their possibility, cannot be so annulled. + +3. On this necessity a priori is also founded the possibility of +apodeictic principles of the relations of time, or axioms of time in +general, such as: "Time has only one dimension," "Different times +are not coexistent but successive" (as different spaces are not +successive but coexistent). These principles cannot be derived from +experience, for it would give neither strict universality, nor +apodeictic certainty. We should only be able to say, "so common +experience teaches us," but not "it must be so." They are valid as +rules, through which, in general, experience is possible; and they +instruct us respecting experience, and not by means of it. + +4. Time is not a discursive, or as it is called, general conception, +but a pure form of the sensuous intuition. Different times are +merely parts of one and the same time. But the representation which +can only be given by a single object is an intuition. Besides, the +proposition that different times cannot be coexistent could not be +derived from a general conception. For this proposition is +synthetical, and therefore cannot spring out of conceptions alone. +It is therefore contained immediately in the intuition and +representation of time. + +5. The infinity of time signifies nothing more than that every +determined quantity of time is possible only through limitations of +one time lying at the foundation. Consequently, the original +representation, time, must be given as unlimited. But as the +determinate representation of the parts of time and of every +quantity of an object can only be obtained by limitation, the complete +representation of time must not be furnished by means of +conceptions, for these contain only partial representations. +Conceptions, on the contrary, must have immediate intuition for +their basis. + + + +SS 6 Transcendental Exposition of the Conception of Time. + +I may here refer to what is said above (SS 5, 3), where, for or sake +of brevity, I have placed under the head of metaphysical exposition, +that which is properly transcendental. Here I shall add that the +conception of change, and with it the conception of motion, as +change of place, is possible only through and in the representation +of time; that if this representation were not an intuition (internal) +a priori, no conception, of whatever kind, could render comprehensible +the possibility of change, in other words, of a conjunction of +contradictorily opposed predicates in one and the same object, for +example, the presence of a thing in a place and the non-presence of +the same thing in the same place. It is only in time that it is +possible to meet with two contradictorily opposed determinations in +one thing, that is, after each other. Thus our conception of time +explains the possibility of so much synthetical knowledge a priori, +as is exhibited in the general doctrine of motion, which is not a +little fruitful. + + + +SS 7. Conclusions from the above Conceptions. + +(a) Time is not something which subsists of itself, or which inheres +in things as an objective determination, and therefore remains, when +abstraction is made of the subjective conditions of the intuition of +things. For in the former case, it would be something real, yet +without presenting to any power of perception any real object. In +the latter case, as an order or determination inherent in things +themselves, it could not be antecedent to things, as their +condition, nor discerned or intuited by means of synthetical +propositions a priori. But all this is quite possible when we regard +time as merely the subjective condition under which all our intuitions +take place. For in that case, this form of the inward intuition can +be represented prior to the objects, and consequently a priori. + +(b) Time is nothing else than the form of the internal sense, that +is, of the intuitions of self and of our internal state. For time +cannot be any determination of outward phenomena. It has to do neither +with shape nor position; on the contrary, it determines the relation +of representations in our internal state. And precisely because this +internal intuition presents to us no shape or form, we endeavour to +supply this want by analogies, and represent the course of time by +a line progressing to infinity, the content of which constitutes a +series which is only of one dimension; and we conclude from the +properties of this line as to all the properties of time, with this +single exception, that the parts of the line are coexistent, whilst +those of time are successive. From this it is clear also that the +representation of time is itself an intuition, because all its +relations can be expressed in an external intuition. + +(c) Time is the formal condition a priori of all phenomena whatsoever. +Space, as the pure form of external intuition, is limited as a +condition a priori to external phenomena alone. On the other hand, +because all representations, whether they have or have not external +things for their objects, still in themselves, as determinations of the +mind, belong to our internal state; and because this internal state is +subject to the formal condition of the internal intuition, that is, to +time--time is a condition a priori of all phenomena whatsoever--the +immediate condition of all internal, and thereby the mediate condition +of all external phenomena. If I can say a priori, "All outward +phenomena are in space, and determined a priori according to the +relations of space," I can also, from the principle of the internal +sense, affirm universally, "All phenomena in general, that is, all +objects of the senses, are in time and stand necessarily in relations +of time." + +If we abstract our internal intuition of ourselves and all external +intuitions, possible only by virtue of this internal intuition and +presented to us by our faculty of representation, and consequently take +objects as they are in themselves, then time is nothing. It is only of +objective validity in regard to phenomena, because these are things +which we regard as objects of our senses. It no longer objective we, +make abstraction of the sensuousness of our intuition, in other words, +of that mode of representation which is peculiar to us, and speak of +things in general. Time is therefore merely a subjective condition of +our (human) intuition (which is always sensuous, that is, so far as we +are affected by objects), and in itself, independently of the mind or +subject, is nothing. Nevertheless, in respect of all phenomena, +consequently of all things which come within the sphere of our +experience, it is necessarily objective. We cannot say, "All things are +in time," because in this conception of things in general, we abstract +and make no mention of any sort of intuition of things. But this is the +proper condition under which time belongs to our representation of +objects. If we add the condition to the conception, and say, "All +things, as phenomena, that is, objects of sensuous intuition, are in +time," then the proposition has its sound objective validity and +universality a priori. + +What we have now set forth teaches, therefore, the empirical reality +of time; that is, its objective validity in reference to all objects +which can ever be presented to our senses. And as our intuition is +always sensuous, no object ever can be presented to us in +experience, which does not come under the conditions of time. On the +other hand, we deny to time all claim to absolute reality; that is, +we deny that it, without having regard to the form of our sensuous +intuition, absolutely inheres in things as a condition or property. +Such properties as belong to objects as things in themselves never +can be presented to us through the medium of the senses. Herein +consists, therefore, the transcendental ideality of time, according +to which, if we abstract the subjective conditions of sensuous intuition, +it is nothing, and cannot be reckoned as subsisting or inhering in +objects as things in themselves, independently of its relation to +our intuition. This ideality, like that of space, is not to be +proved or illustrated by fallacious analogies with sensations, for +this reason--that in such arguments or illustrations, we make the +presupposition that the phenomenon, in which such and such +predicates inhere, has objective reality, while in this case we can +only find such an objective reality as is itself empirical, that is, +regards the object as a mere phenomenon. In reference to this subject, +see the remark in Section I (SS 4) + + + +SS 8. Elucidation. + +Against this theory, which grants empirical reality to time, but denies +to it absolute and transcendental reality, I have heard from +intelligent men an objection so unanimously urged that I conclude that +it must naturally present itself to every reader to whom these +considerations are novel. It runs thus: "Changes are real" (this the +continual change in our own representations demonstrates, even though +the existence of all external phenomena, together with their changes, +is denied). Now, changes are only possible in time, and therefore time +must be something real. But there is no difficulty in answering this. I +grant the whole argument. Time, no doubt, is something real, that is, +it is the real form of our internal intuition. It therefore has +subjective reality, in reference to our internal experience, that is, I +have really the representation of time and of my determinations +therein. Time, therefore, is not to be regarded as an object, but as +the mode of representation of myself as an object. But if I could +intuite myself, or be intuited by another being, without this condition +of sensibility, then those very determinations which we now represent +to ourselves as changes, would present to us a knowledge in which the +representation of time, and consequently of change, would not appear. +The empirical reality of time, therefore, remains, as the condition of +all our experience. But absolute reality, according to what has been +said above, cannot be granted it. Time is nothing but the form of our +internal intuition.* If we take away from it the special condition of +our sensibility, the conception of time also vanishes; and it inheres +not in the objects themselves, but solely in the subject (or mind) +which intuites them. + +[*Footnote: I can indeed say "my representations follow one another, +or are successive"; but this means only that we are conscious of them +as in a succession, that is, according to the form of the internal +sense. Time, therefore, is not a thing in itself, nor is it any objective +determination pertaining to, or inherent in things.] + +But the reason why this objection is so unanimously brought +against our doctrine of time, and that too by disputants who cannot +start any intelligible arguments against the doctrine of the +ideality of space, is this--they have no hope of demonstrating +apodeictically the absolute reality of space, because the doctrine +of idealism is against them, according to which the reality of +external objects is not capable of any strict proof. On the other +hand, the reality of the object of our internal sense (that is, myself +and my internal state) is clear immediately through consciousness. +The former--external objects in space--might be a mere delusion, but +the latter--the object of my internal perception--is undeniably real. +They do not, however, reflect that both, without question of their +reality as representations, belong only to the genus phenomenon, which +has always two aspects, the one, the object considered as a thing in +itself, without regard to the mode of intuiting it, and the nature +of which remains for this very reason problematical, the other, the +form of our intuition of the object, which must be sought not in the +object as a thing in itself, but in the subject to which it appears-- +which form of intuition nevertheless belongs really and necessarily +to the phenomenal object. + +Time and space are, therefore, two sources of knowledge, from which, +a priori, various synthetical cognitions can be drawn. Of this we find +a striking example in the cognitions of space and its relations, which +form the foundation of pure mathematics. They are the two pure forms +of all intuitions, and thereby make synthetical propositions a +priori possible. But these sources of knowledge being merely +conditions of our sensibility, do therefore, and as such, strictly +determine their own range and purpose, in that they do not and +cannot present objects as things in themselves, but are applicable +to them solely in so far as they are considered as sensuous phenomena. +The sphere of phenomena is the only sphere of their validity, and if +we venture out of this, no further objective use can be made of +them. For the rest, this formal reality of time and space leaves the +validity of our empirical knowledge unshaken; for our certainty in +that respect is equally firm, whether these forms necessarily inhere +in the things themselves, or only in our intuitions of them. On the +other hand, those who maintain the absolute reality of time and space, +whether as essentially subsisting, or only inhering, as modifications, +in things, must find themselves at utter variance with the +principles of experience itself. For, if they decide for the first +view, and make space and time into substances, this being the side +taken by mathematical natural philosophers, they must admit two +self-subsisting nonentities, infinite and eternal, which exist (yet +without there being anything real) for the purpose of containing in +themselves everything that is real. If they adopt the second view of +inherence, which is preferred by some metaphysical natural +philosophers, and regard space and time as relations (contiguity in +space or succession in time), abstracted from experience, though +represented confusedly in this state of separation, they find +themselves in that case necessitated to deny the validity of +mathematical doctrines a priori in reference to real things (for +example, in space)--at all events their apodeictic certainty. For such +certainty cannot be found in an a posteriori proposition; and the +conceptions a priori of space and time are, according to this opinion, +mere creations of the imagination, having their source really in +experience, inasmuch as, out of relations abstracted from +experience, imagination has made up something which contains, +indeed, general statements of these relations, yet of which no +application can be made without the restrictions attached thereto by +nature. The former of these parties gains this advantage, that they +keep the sphere of phenomena free for mathematical science. On the +other hand, these very conditions (space and time) embarrass them +greatly, when the understanding endeavours to pass the limits of +that sphere. The latter has, indeed, this advantage, that the +representations of space and time do not come in their way when they +wish to judge of objects, not as phenomena, but merely in their +relation to the understanding. Devoid, however, of a true and +objectively valid a priori intuition, they can neither furnish any +basis for the possibility of mathematical cognitions a priori, nor +bring the propositions of experience into necessary accordance with +those of mathematics. In our theory of the true nature of these two +original forms of the sensibility, both difficulties are surmounted. + +In conclusion, that transcendental aesthetic cannot contain any more +than these two elements--space and time, is sufficiently obvious +from the fact that all other conceptions appertaining to +sensibility, even that of motion, which unites in itself both +elements, presuppose something empirical. Motion, for example, +presupposes the perception of something movable. But space +considered in itself contains nothing movable, consequently motion +must be something which is found in space only through experience-- +in other words, an empirical datum. In like manner, transcendental +aesthetic cannot number the conception of change among its data a +priori; for time itself does not change, but only something which is +in time. To acquire the conception of change, therefore, the +perception of some existing object and of the succession of its +determinations, in one word, experience, is necessary. + + + +SS 9. General Remarks on Transcendental Aesthetic. + +I. In order to prevent any misunderstanding, it will be requisite, +in the first place, to recapitulate, as clearly as possible, what +our opinion is with respect to the fundamental nature of our +sensuous cognition in general. We have intended, then, to say that +all our intuition is nothing but the representation of phenomena; that +the things which we intuite, are not in themselves the same as our +representations of them in intuition, nor are their relations in +themselves so constituted as they appear to us; and that if we take +away the subject, or even only the subjective constitution of our +senses in general, then not only the nature and relations of objects +in space and time, but even space and time themselves disappear; and +that these, as phenomena, cannot exist in themselves, but only in +us. What may be the nature of objects considered as things in +themselves and without reference to the receptivity of our sensibility +is quite unknown to us. We know nothing more than our mode of +perceiving them, which is peculiar to us, and which, though not of +necessity pertaining to every animated being, is so to the whole human +race. With this alone we have to do. Space and time are the pure forms +thereof; sensation the matter. The former alone can we cognize a +priori, that is, antecedent to all actual perception; and for this +reason such cognition is called pure intuition. The latter is that +in our cognition which is called cognition a posteriori, that is, +empirical intuition. The former appertain absolutely and necessarily +to our sensibility, of whatsoever kind our sensations may be; the +latter may be of very diversified character. Supposing that we +should carry our empirical intuition even to the very highest degree +of clearness, we should not thereby advance one step nearer to a +knowledge of the constitution of objects as things in themselves. +For we could only, at best, arrive at a complete cognition of our +own mode of intuition, that is of our sensibility, and this always +under the conditions originally attaching to the subject, namely, +the conditions of space and time; while the question: "What are +objects considered as things in themselves?" remains unanswerable even +after the most thorough examination of the phenomenal world. + +To say, then, that all our sensibility is nothing but the confused +representation of things containing exclusively that which belongs +to them as things in themselves, and this under an accumulation of +characteristic marks and partial representations which we cannot +distinguish in consciousness, is a falsification of the conception +of sensibility and phenomenization, which renders our whole doctrine +thereof empty and useless. The difference between a confused and a +clear representation is merely logical and has nothing to do with +content. No doubt the conception of right, as employed by a sound +understanding, contains all that the most subtle investigation could +unfold from it, although, in the ordinary practical use of the word, +we are not conscious of the manifold representations comprised in +the conception. But we cannot for this reason assert that the ordinary +conception is a sensuous one, containing a mere phenomenon, for +right cannot appear as a phenomenon; but the conception of it lies +in the understanding, and represents a property (the moral property) +of actions, which belongs to them in themselves. On the other hand, +the representation in intuition of a body contains nothing which could +belong to an object considered as a thing in itself, but merely the +phenomenon or appearance of something, and the mode in which we are +affected by that appearance; and this receptivity of our faculty of +cognition is called sensibility, and remains toto caelo different from +the cognition of an object in itself, even though we should examine +the content of the phenomenon to the very bottom. + +It must be admitted that the Leibnitz-Wolfian philosophy has +assigned an entirely erroneous point of view to all investigations +into the nature and origin of our cognitions, inasmuch as it regards +the distinction between the sensuous and the intellectual as merely +logical, whereas it is plainly transcendental, and concerns not merely +the clearness or obscurity, but the content and origin of both. For +the faculty of sensibility not only does not present us with an +indistinct and confused cognition of objects as things in +themselves, but, in fact, gives us no knowledge of these at all. On +the contrary, so soon as we abstract in thought our own subjective +nature, the object represented, with the properties ascribed to it +by sensuous intuition, entirely disappears, because it was only this +subjective nature that determined the form of the object as a +phenomenon. + +In phenomena, we commonly, indeed, distinguish that which +essentially belongs to the intuition of them, and is valid for the +sensuous faculty of every human being, from that which belongs to +the same intuition accidentally, as valid not for the sensuous faculty +in general, but for a particular state or organization of this or that +sense. Accordingly, we are accustomed to say that the former is a +cognition which represents the object itself, whilst the latter +presents only a particular appearance or phenomenon thereof. This +distinction, however, is only empirical. If we stop here (as is +usual), and do not regard the empirical intuition as itself a mere +phenomenon (as we ought to do), in which nothing that can appertain +to a thing in itself is to be found, our transcendental distinction +is lost, and we believe that we cognize objects as things in +themselves, although in the whole range of the sensuous world, +investigate the nature of its objects as profoundly as we may, we have +to do with nothing but phenomena. Thus, we call the rainbow a mere +appearance of phenomenon in a sunny shower, and the rain, the +reality or thing in itself; and this is right enough, if we understand +the latter conception in a merely physical sense, that is, as that +which in universal experience, and under whatever conditions of +sensuous perception, is known in intuition to be so and so determined, +and not otherwise. But if we consider this empirical datum +generally, and inquire, without reference to its accordance with all +our senses, whether there can be discovered in it aught which +represents an object as a thing in itself (the raindrops of course +are not such, for they are, as phenomena, empirical objects), the question +of the relation of the representation to the object is transcendental; +and not only are the raindrops mere phenomena, but even their circular +form, nay, the space itself through which they fall, is nothing in +itself, but both are mere modifications or fundamental dispositions +of our sensuous intuition, whilst the transcendental object remains +for us utterly unknown. + +The second important concern of our aesthetic is that it does not +obtain favour merely as a plausible hypothesis, but possess as +undoubted a character of certainty as can be demanded of any theory +which is to serve for an organon. In order fully to convince the +reader of this certainty, we shall select a case which will serve to +make its validity apparent, and also to illustrate what has been +said in SS 3. + +Suppose, then, that space and time are in themselves objective, +and conditions of the--possibility of objects as things in themselves. +In the first place, it is evident that both present us, with very many +apodeictic and synthetic propositions a priori, but especially +space--and for this reason we shall prefer it for investigation at +present. As the propositions of geometry are cognized synthetically +a priori, and with apodeictic certainty, I inquire: Whence do you +obtain propositions of this kind, and on what basis does the +understanding rest, in order to arrive at such absolutely necessary +and universally valid truths? + +There is no other way than through intuitions or conceptions, as +such; and these are given either a priori or a posteriori. The latter, +namely, empirical conceptions, together with the empirical intuition +on which they are founded, cannot afford any synthetical +proposition, except such as is itself also empirical, that is, a +proposition of experience. But an empirical proposition cannot possess +the qualities of necessity and absolute universality, which, +nevertheless, are the characteristics of all geometrical propositions. +As to the first and only means to arrive at such cognitions, namely, +through mere conceptions or intuitions a priori, it is quite clear +that from mere conceptions no synthetical cognitions, but only +analytical ones, can be obtained. Take, for example, the +proposition: "Two straight lines cannot enclose a space, and with +these alone no figure is possible," and try to deduce it from the +conception of a straight line and the number two; or take the +proposition: "It is possible to construct a figure with three straight +lines," and endeavour, in like manner, to deduce it from the mere +conception of a straight line and the number three. All your +endeavours are in vain, and you find yourself forced to have +recourse to intuition, as, in fact, geometry always does. You +therefore give yourself an object in intuition. But of what kind is +this intuition? Is it a pure a priori, or is it an empirical +intuition? If the latter, then neither an universally valid, much less +an apodeictic proposition can arise from it, for experience never +can give us any such proposition. You must, therefore, give yourself +an object a priori in intuition, and upon that ground your synthetical +proposition. Now if there did not exist within you a faculty of +intuition a priori; if this subjective condition were not in respect +to its form also the universal condition a priori under which alone +the object of this external intuition is itself possible; if the +object (that is, the triangle) were something in itself, without +relation to you the subject; how could you affirm that that which lies +necessarily in your subjective conditions in order to construct a +triangle, must also necessarily belong to the triangle in itself? +For to your conceptions of three lines, you could not add anything +new (that is, the figure); which, therefore, must necessarily be found +in the object, because the object is given before your cognition, +and not by means of it. If, therefore, space (and time also) were +not a mere form of your intuition, which contains conditions a priori, +under which alone things can become external objects for you, and +without which subjective conditions the objects are in themselves +nothing, you could not construct any synthetical proposition +whatsoever regarding external objects. It is therefore not merely +possible or probable, but indubitably certain, that space and time, +as the necessary conditions of all our external and internal +experience, are merely subjective conditions of all our intuitions, +in relation to which all objects are therefore mere phenomena, and +not things in themselves, presented to us in this particular manner. +And for this reason, in respect to the form of phenomena, much may +be said a priori, whilst of the thing in itself, which may lie at the +foundation of these phenomena, it is impossible to say anything. + +II. In confirmation of this theory of the ideality of the external +as well as internal sense, consequently of all objects of sense, as +mere phenomena, we may especially remark that all in our cognition +that belongs to intuition contains nothing more than mere relations. +(The feelings of pain and pleasure, and the will, which are not +cognitions, are excepted.) The relations, to wit, of place in an +intuition (extension), change of place (motion), and laws according +to which this change is determined (moving forces). That, however, +which is present in this or that place, or any operation going on, +or result taking place in the things themselves, with the exception +of change of place, is not given to us by intuition. Now by means of +mere relations, a thing cannot be known in itself; and it may therefore +be fairly concluded, that, as through the external sense nothing but +mere representations of relations are given us, the said external +sense in its representation can contain only the relation of the +object to the subject, but not the essential nature of the object as +a thing in itself. + +The same is the case with the internal intuition, not only +because, in the internal intuition, the representation of the external +senses constitutes the material with which the mind is occupied; but +because time, in which we place, and which itself antecedes the +consciousness of, these representations in experience, and which, as +the formal condition of the mode according to which objects are placed +in the mind, lies at the foundation of them, contains relations of +the successive, the coexistent, and of that which always must be +coexistent with succession, the permanent. Now that which, as +representation, can antecede every exercise of thought (of an object), +is intuition; and when it contains nothing but relations, it is the +form of the intuition, which, as it presents us with no +representation, except in so far as something is placed in the mind, +can be nothing else than the mode in which the mind is affected by +its own activity, to wit--its presenting to itself representations, +consequently the mode in which the mind is affected by itself; that +is, it can be nothing but an internal sense in respect to its form. +Everything that is represented through the medium of sense is so far +phenomenal; consequently, we must either refuse altogether to admit +an internal sense, or the subject, which is the object of that sense, +could only be represented by it as phenomenon, and not as it would +judge of itself, if its intuition were pure spontaneous activity, that +is, were intellectual. The difficulty here lies wholly in the +question: How can the subject have an internal intuition of itself? +But this difficulty is common to every theory. The consciousness of +self (apperception) is the simple representation of the "ego"; and +if by means of that representation alone, all the manifold +representations in the subject were spontaneously given, then our +internal intuition would be intellectual. This consciousness in man +requires an internal perception of the manifold representations +which are previously given in the subject; and the manner in which +these representations are given in the mind without spontaneity, must, +on account of this difference (the want of spontaneity), be called +sensibility. If the faculty of self-consciousness is to apprehend what +lies in the mind, it must all act that and can in this way alone +produce an intuition of self. But the form of this intuition, which +lies in the original constitution of the mind, determines, in the +representation of time, the manner in which the manifold +representations are to combine themselves in the mind; since the +subject intuites itself, not as it would represent itself +immediately and spontaneously, but according to the manner in which +the mind is internally affected, consequently, as it appears, and +not as it is. + +III. When we say that the intuition of external objects, and also +the self-intuition of the subject, represent both, objects and +subject, in space and time, as they affect our senses, that is, as +they appear--this is by no means equivalent to asserting that these +objects are mere illusory appearances. For when we speak of things +as phenomena, the objects, nay, even the properties which we ascribe +to them, are looked upon as really given; only that, in so far as this +or that property depends upon the mode of intuition of the subject, +in the relation of the given object to the subject, the object as +phenomenon is to be distinguished from the object as a thing in +itself. Thus I do not say that bodies seem or appear to be external +to me, or that my soul seems merely to be given in my self-consciousness, +although I maintain that the properties of space and time, in +conformity to which I set both, as the condition of their existence, +abide in my mode of intuition, and not in the objects in themselves. +It would be my own fault, if out of that which I should reckon as +phenomenon, I made mere illusory appearance.* But this will not +happen, because of our principle of the ideality of all sensuous +intuitions. On the contrary, if we ascribe objective reality to +these forms of representation, it becomes impossible to avoid changing +everything into mere appearance. For if we regard space and time as +properties, which must be found in objects as things in themselves, +as sine quibus non of the possibility of their existence, and reflect +on the absurdities in which we then find ourselves involved, +inasmuch as we are compelled to admit the existence of two infinite +things, which are nevertheless not substances, nor anything really +inhering in substances, nay, to admit that they are the necessary +conditions of the existence of all things, and moreover, that they +must continue to exist, although all existing things were annihilated-- +we cannot blame the good Berkeley for degrading bodies to mere +illusory appearances. Nay, even our own existence, which would in this +case depend upon the self-existent reality of such a mere nonentity +as time, would necessarily be changed with it into mere appearance--an +absurdity which no one has as yet been guilty of. + +[*Footnote: The predicates of the phenomenon can be affixed to the +object itself in relation to our sensuous faculty; for example, the +red colour or the perfume to the rose. But (illusory) appearance never +can be attributed as a predicate to an object, for this very reason, +that it attributes to this object in itself that which belongs to it +only in relation to our sensuous faculty, or to the subject in +general, e.g., the two handles which were formerly ascribed to Saturn. +That which is never to be found in the object itself, but always in +the relation of the object to the subject, and which moreover is +inseparable from our representation of the object, we denominate +phenomenon. Thus the predicates of space and time are rightly +attributed to objects of the senses as such, and in this there is no +illusion. On the contrary, if I ascribe redness of the rose as a thing +in itself, or to Saturn his handles, or extension to all external +objects, considered as things in themselves, without regarding the +determinate relation of these objects to the subject, and without +limiting my judgement to that relation--then, and then only, arises +illusion.] + +IV. In natural theology, where we think of an object--God--which +never can be an object of intuition to us, and even to himself can +never be an object of sensuous intuition, we carefully avoid +attributing to his intuition the conditions of space and time--and +intuition all his cognition must be, and not thought, which always +includes limitation. But with what right can we do this if we make +them forms of objects as things in themselves, and such, moreover, +as would continue to exist as a priori conditions of the existence +of things, even though the things themselves were annihilated? For +as conditions of all existence in general, space and time must be +conditions of the existence of the Supreme Being also. But if we do +not thus make them objective forms of all things, there is no other +way left than to make them subjective forms of our mode of +intuition--external and internal; which is called sensuous, because +it is not primitive, that is, is not such as gives in itself the +existence of the object of the intuition (a mode of intuition which, +so far as we can judge, can belong only to the Creator), but is +dependent on the existence of the object, is possible, therefore, only +on condition that the representative faculty of the subject is +affected by the object. + +It is, moreover, not necessary that we should limit the mode of +intuition in space and time to the sensuous faculty of man. It may +well be that all finite thinking beings must necessarily in this +respect agree with man (though as to this we cannot decide), but +sensibility does not on account of this universality cease to be +sensibility, for this very reason, that it is a deduced (intuitus +derivativus), and not an original (intuitus originarius), consequently +not an intellectual intuition, and this intuition, as such, for +reasons above mentioned, seems to belong solely to the Supreme +Being, but never to a being dependent, quoad its existence, as well +as its intuition (which its existence determines and limits relatively +to given objects). This latter remark, however, must be taken only +as an illustration, and not as any proof of the truth of our +aesthetical theory. + + + +SS 10. Conclusion of the Transcendental Aesthetic. + +We have now completely before us one part of the solution of the +grand general problem of transcendental philosophy, namely, the +question: "How are synthetical propositions a priori possible?" That +is to say, we have shown that we are in possession of pure a priori +intuitions, namely, space and time, in which we find, when in a +judgement a priori we pass out beyond the given conception, +something which is not discoverable in that conception, but is +certainly found a priori in the intuition which corresponds to the +conception, and can be united synthetically with it. But the +judgements which these pure intuitions enable us to make, never +reach farther than to objects of the senses, and are valid only for +objects of possible experience. + + + + +SECOND PART. TRANSCENDENTAL LOGIC. + +INTRODUCTION. Idea of a Transcendental Logic. + +I. Of Logic in General. + +Our knowledge springs from two main sources in the mind, first of +which is the faculty or power of receiving representations +(receptivity for impressions); the second is the power of cognizing +by means of these representations (spontaneity in the production of +conceptions). Through the first an object is given to us; through +the second, it is, in relation to the representation (which is a +mere determination of the mind), thought. Intuition and conceptions +constitute, therefore, the elements of all our knowledge, so that +neither conceptions without an intuition in some way corresponding +to them, nor intuition without conceptions, can afford us a cognition. +Both are either pure or empirical. They are empirical, when sensation +(which presupposes the actual presence of the object) is contained +in them; and pure, when no sensation is mixed with the representation. +Sensations we may call the matter of sensuous cognition. Pure +intuition consequently contains merely the form under which +something is intuited, and pure conception only the form of the +thought of an object. Only pure intuitions and pure conceptions are +possible a priori; the empirical only a posteriori. + +We apply the term sensibility to the receptivity of the mind for +impressions, in so far as it is in some way affected; and, on the +other hand, we call the faculty of spontaneously producing +representations, or the spontaneity of cognition, understanding. Our +nature is so constituted that intuition with us never can be other +than sensuous, that is, it contains only the mode in which we are +affected by objects. On the other hand, the faculty of thinking the +object of sensuous intuition is the understanding. Neither of these +faculties has a preference over the other. Without the sensuous +faculty no object would be given to us, and without the +understanding no object would be thought. Thoughts without content +are void; intuitions without conceptions, blind. Hence it is as +necessary for the mind to make its conceptions sensuous (that is, to +join to them the object in intuition), as to make its intuitions +intelligible (that is, to bring them under conceptions). Neither of +these faculties can exchange its proper function. Understanding cannot +intuite, and the sensuous faculty cannot think. In no other way than +from the united operation of both, can knowledge arise. But no one +ought, on this account, to overlook the difference of the elements +contributed by each; we have rather great reason carefully to separate +and distinguish them. We therefore distinguish the science of the laws +of sensibility, that is, aesthetic, from the science of the laws of +the understanding, that is, logic. + +Now, logic in its turn may be considered as twofold--namely, as +logic of the general, or of the particular use of the understanding. +The first contains the absolutely necessary laws of thought, without +which no use whatsoever of the understanding is possible, and gives +laws therefore to the understanding, without regard to the +difference of objects on which it may be employed. The logic of the +particular use of the understanding contains the laws of correct +thinking upon a particular class of objects. The former may be +called elemental logic--the latter, the organon of this or that +particular science. The latter is for the most part employed in the +schools, as a propaedeutic to the sciences, although, indeed, +according to the course of human reason, it is the last thing we +arrive at, when the science has been already matured, and needs only +the finishing touches towards its correction and completion; for our +knowledge of the objects of our attempted science must be tolerably +extensive and complete before we can indicate the laws by which a +science of these objects can be established. + +General logic is again either pure or applied. In the former, we +abstract all the empirical conditions under which the understanding +is exercised; for example, the influence of the senses, the play of +the fantasy or imagination, the laws of the memory, the force of habit, +of inclination, etc., consequently also, the sources of prejudice--in +a word, we abstract all causes from which particular cognitions arise, +because these causes regard the understanding under certain +circumstances of its application, and, to the knowledge of them +experience is required. Pure general logic has to do, therefore, +merely with pure a priori principles, and is a canon of +understanding and reason, but only in respect of the formal part of +their use, be the content what it may, empirical or transcendental. +General logic is called applied, when it is directed to the laws of +the use of the understanding, under the subjective empirical +conditions which psychology teaches us. It has therefore empirical +principles, although, at the same time, it is in so far general, +that it applies to the exercise of the understanding, without regard +to the difference of objects. On this account, moreover, it is neither +a canon of the understanding in general, nor an organon of a +particular science, but merely a cathartic of the human understanding. + +In general logic, therefore, that part which constitutes pure +logic must be carefully distinguished from that which constitutes +applied (though still general) logic. The former alone is properly +science, although short and dry, as the methodical exposition of an +elemental doctrine of the understanding ought to be. In this, +therefore, logicians must always bear in mind two rules: + +1. As general logic, it makes abstraction of all content of the +cognition of the understanding, and of the difference of objects, +and has to do with nothing but the mere form of thought. + +2. As pure logic, it has no empirical principles, and consequently +draws nothing (contrary to the common persuasion) from psychology, +which therefore has no influence on the canon of the understanding. +It is a demonstrated doctrine, and everything in it must be certain +completely a priori. + +What I called applied logic (contrary to the common acceptation of +this term, according to which it should contain certain exercises +for the scholar, for which pure logic gives the rules), is a +representation of the understanding, and of the rules of its necessary +employment in concreto, that is to say, under the accidental +conditions of the subject, which may either hinder or promote this +employment, and which are all given only empirically. Thus applied +logic treats of attention, its impediments and consequences, of the +origin of error, of the state of doubt, hesitation, conviction, +etc., and to it is related pure general logic in the same way that +pure morality, which contains only the necessary moral laws of a +free will, is related to practical ethics, which considers these +laws under all the impediments of feelings, inclinations, and passions +to which men are more or less subjected, and which never can furnish +us with a true and demonstrated science, because it, as well as +applied logic, requires empirical and psychological principles. + + + +II. Of Transcendental Logic. + +General logic, as we have seen, makes abstraction of all content +of cognition, that is, of all relation of cognition to its object, +and regards only the logical form in the relation of cognitions to +each other, that is, the form of thought in general. But as we have +both pure and empirical intuitions (as transcendental aesthetic proves), +in like manner a distinction might be drawn between pure and empirical +thought (of objects). In this case, there would exist a kind of logic, +in which we should not make abstraction of all content of cognition; +for or logic which should comprise merely the laws of pure thought +(of an object), would of course exclude all those cognitions which +were of empirical content. This kind of logic would also examine the +origin of our cognitions of objects, so far as that origin cannot be +ascribed to the objects themselves; while, on the contrary, general +logic has nothing to do with the origin of our cognitions, but contemplates +our representations, be they given primitively a priori in +ourselves, or be they only of empirical origin, solely according to +the laws which the understanding observes in employing them in the +process of thought, in relation to each other. Consequently, general +logic treats of the form of the understanding only, which can be +applied to representations, from whatever source they may have arisen. + +And here I shall make a remark, which the reader must bear well in +mind in the course of the following considerations, to wit, that not +every cognition a priori, but only those through which we cognize that +and how certain representations (intuitions or conceptions) are +applied or are possible only a priori; that is to say, the a priori +possibility of cognition and the a priori use of it are +transcendental. Therefore neither is space, nor any a priori +geometrical determination of space, a transcendental Representation, +but only the knowledge that such a representation is not of +empirical origin, and the possibility of its relating to objects of +experience, although itself a priori, can be called transcendental. +So also, the application of space to objects in general would be +transcendental; but if it be limited to objects of sense it is +empirical. Thus, the distinction of the transcendental and empirical +belongs only to the critique of cognitions, and does not concern the +relation of these to their object. + +Accordingly, in the expectation that there may perhaps be +conceptions which relate a priori to objects, not as pure or +sensuous intuitions, but merely as acts of pure thought (which are +therefore conceptions, but neither of empirical nor aesthetical +origin)--in this expectation, I say, we form to ourselves, by +anticipation, the idea of a science of pure understanding and rational +cognition, by means of which we may cogitate objects entirely a +priori. A science of this kind, which should determine the origin, +the extent, and the objective validity of such cognitions, must be +called transcendental logic, because it has not, like general logic, +to do with the laws of understanding and reason in relation to +empirical as well as pure rational cognitions without distinction, +but concerns itself with these only in an a priori relation to objects. + + + +III. Of the Division of General Logic into Analytic and Dialectic. + +The old question with which people sought to push logicians into a +corner, so that they must either have recourse to pitiful sophisms +or confess their ignorance, and consequently the vanity of their whole +art, is this: "What is truth?" The definition of the word truth, to +wit, "the accordance of the cognition with its object," is presupposed +in the question; but we desire to be told, in the answer to it, what +is the universal and secure criterion of the truth of every cognition. + +To know what questions we may reasonably propose is in itself a +strong evidence of sagacity and intelligence. For if a question be +in itself absurd and unsusceptible of a rational answer, it is +attended with the danger--not to mention the shame that falls upon +the person who proposes it--of seducing the unguarded listener into +making absurd answers, and we are presented with the ridiculous spectacle +of one (as the ancients said) "milking the he-goat, and the other +holding a sieve." + +If truth consists in the accordance of a cognition with its +object, this object must be, ipso facto, distinguished from all +others; for a cognition is false if it does not accord with the object +to which it relates, although it contains something which may be +affirmed of other objects. Now an universal criterion of truth would +be that which is valid for all cognitions, without distinction of +their objects. But it is evident that since, in the case of such a +criterion, we make abstraction of all the content of a cognition (that +is, of all relation to its object), and truth relates precisely to +this content, it must be utterly absurd to ask for a mark of the truth +of this content of cognition; and that, accordingly, a sufficient, +and at the same time universal, test of truth cannot possibly be found. +As we have already termed the content of a cognition its matter, we +shall say: "Of the truth of our cognitions in respect of their matter, +no universal test can be demanded, because such a demand is +self-contradictory." + +On the other hand, with regard to our cognition in respect of its +mere form (excluding all content), it is equally manifest that +logic, in so far as it exhibits the universal and necessary laws of +the understanding, must in these very laws present us with criteria +of truth. Whatever contradicts these rules is false, because thereby +the understanding is made to contradict its own universal laws of +thought; that is, to contradict itself. These criteria, however, apply +solely to the form of truth, that is, of thought in general, and in +so far they are perfectly accurate, yet not sufficient. For although +a cognition may be perfectly accurate as to logical form, that is, +not self-contradictory, it is notwithstanding quite possible that it +may not stand in agreement with its object. Consequently, the merely +logical criterion of truth, namely, the accordance of a cognition with +the universal and formal laws of understanding and reason, is +nothing more than the conditio sine qua non, or negative condition +of all truth. Farther than this logic cannot go, and the error which +depends not on the form, but on the content of the cognition, it has +no test to discover. + +General logic, then, resolves the whole formal business of +understanding and reason into its elements, and exhibits them as +principles of all logical judging of our cognitions. This part of +logic may, therefore, be called analytic, and is at least the negative +test of truth, because all cognitions must first of an be estimated +and tried according to these laws before we proceed to investigate +them in respect of their content, in order to discover whether they +contain positive truth in regard to their object. Because, however, +the mere form of a cognition, accurately as it may accord with logical +laws, is insufficient to supply us with material (objective) truth, +no one, by means of logic alone, can venture to predicate anything +of or decide concerning objects, unless he has obtained, independently +of logic, well-grounded information about them, in order afterwards +to examine, according to logical laws, into the use and connection, +in a cohering whole, of that information, or, what is still better, +merely to test it by them. Notwithstanding, there lies so seductive +a charm in the possession of a specious art like this--an art which +gives to all our cognitions the form of the understanding, although +with respect to the content thereof we may be sadly deficient--that +general logic, which is merely a canon of judgement, has been employed +as an organon for the actual production, or rather for the semblance +of production, of objective assertions, and has thus been grossly +misapplied. Now general logic, in its assumed character of organon, +is called dialectic. + +Different as are the significations in which the ancients used +this term for a science or an art, we may safely infer, from their +actual employment of it, that with them it was nothing else than a +logic of illusion--a sophistical art for giving ignorance, nay, even +intentional sophistries, the colouring of truth, in which the +thoroughness of procedure which logic requires was imitated, and their +topic employed to cloak the empty pretensions. Now it may be taken +as a safe and useful warning, that general logic, considered as an +organon, must always be a logic of illusion, that is, be +dialectical, for, as it teaches us nothing whatever respecting the +content of our cognitions, but merely the formal conditions of their +accordance with the understanding, which do not relate to and are +quite indifferent in respect of objects, any attempt to employ it as +an instrument (organon) in order to extend and enlarge the range of +our knowledge must end in mere prating; any one being able to maintain +or oppose, with some appearance of truth, any single assertion +whatever. + +Such instruction is quite unbecoming the dignity of philosophy. +For these reasons we have chosen to denominate this part of logic +dialectic, in the sense of a critique of dialectical illusion, and +we wish the term to be so understood in this place. + + + +IV. Of the Division of Transcendental Logic into Transcendental + Analytic and Dialectic. + +In transcendental logic we isolate the understanding (as in +transcendental aesthetic the sensibility) and select from our +cognition merely that part of thought which has its origin in the +understanding alone. The exercise of this pure cognition, however, +depends upon this as its condition, that objects to which it may be +applied be given to us in intuition, for without intuition the whole +of our cognition is without objects, and is therefore quite void. That +part of transcendental logic, then, which treats of the elements of +pure cognition of the understanding, and of the principles without +which no object at all can be thought, is transcendental analytic, +and at the same time a logic of truth. For no cognition can contradict +it, without losing at the same time all content, that is, losing all +reference to an object, and therefore all truth. But because we are +very easily seduced into employing these pure cognitions and +principles of the understanding by themselves, and that even beyond +the boundaries of experience, which yet is the only source whence we +can obtain matter (objects) on which those pure conceptions may be +employed--understanding runs the risk of making, by means of empty +sophisms, a material and objective use of the mere formal principles +of the pure understanding, and of passing judgements on objects +without distinction--objects which are not given to us, nay, perhaps +cannot be given to us in any way. Now, as it ought properly to be only +a canon for judging of the empirical use of the understanding, this +kind of logic is misused when we seek to employ it as an organon of +the universal and unlimited exercise of the understanding, and attempt +with the pure understanding alone to judge synthetically, affirm, +and determine respecting objects in general. In this case the exercise +of the pure understanding becomes dialectical. The second part of +our transcendental logic must therefore be a critique of dialectical +illusion, and this critique we shall term transcendental dialectic-- +not meaning it as an art of producing dogmatically such illusion (an +art which is unfortunately too current among the practitioners of +metaphysical juggling), but as a critique of understanding and +reason in regard to their hyperphysical use. This critique will expose +the groundless nature of the pretensions of these two faculties, and +invalidate their claims to the discovery and enlargement of our +cognitions merely by means of transcendental principles, and show that +the proper employment of these faculties is to test the judgements +made by the pure understanding, and to guard it from sophistical +delusion. + + + + +TRANSCENDENTAL LOGIC. FIRST DIVISION. + +TRANSCENDENTAL ANALYTIC. + +SS I. + +Transcendental analytic is the dissection of the whole of our a priori +knowledge into the elements of the pure cognition of the understanding. +In order to effect our purpose, it is necessary: (1) That the +conceptions be pure and not empirical; (2) That they belong not to +intuition and sensibility, but to thought and understanding; (3) That +they be elementary conceptions, and as such, quite different from +deduced or compound conceptions; (4) That our table of these elementary +conceptions be complete, and fill up the whole sphere of the pure +understanding. Now this completeness of a science cannot be accepted +with confidence on the guarantee of a mere estimate of its existence in +an aggregate formed only by means of repeated experiments and attempts. +The completeness which we require is possible only by means of an idea +of the totality of the a priori cognition of the understanding, and +through the thereby determined division of the conceptions which form +the said whole; consequently, only by means of their connection in a +system. Pure understanding distinguishes itself not merely from +everything empirical, but also completely from all sensibility. It is a +unity self-subsistent, self-sufficient, and not to be enlarged by any +additions from without. Hence the sum of its cognition constitutes a +system to be determined by and comprised under an idea; and the +completeness and articulation of this system can at the same time serve +as a test of the correctness and genuineness of all the parts of +cognition that belong to it. The whole of this part of transcendental +logic consists of two books, of which the one contains the conceptions, +and the other the principles of pure understanding. + + + +BOOK I. + +SS 2. Analytic of Conceptions. + +By the term Analytic of Conceptions, I do not understand the +analysis of these, or the usual process in philosophical +investigations of dissecting the conceptions which present themselves, +according to their content, and so making them clear; but I mean the +hitherto little attempted dissection of the faculty of understanding +itself, in order to investigate the possibility of conceptions a +priori, by looking for them in the understanding alone, as their +birthplace, and analysing the pure use of this faculty. For this is +the proper duty of a transcendental philosophy; what remains is the +logical treatment of the conceptions in philosophy in general. We +shall therefore follow up the pure conceptions even to their germs +and beginnings in the human understanding, in which they lie, until +they are developed on occasions presented by experience, and, freed +by the same understanding from the empirical conditions attaching to +them, are set forth in their unalloyed purity. + + + +CHAPTER I. Of the Transcendental Clue to the Discovery of all Pure + Conceptions of the Understanding. + +SS 3. Introductory. + +When we call into play a faculty of cognition, different conceptions +manifest themselves according to the different circumstances, and make +known this faculty, and assemble themselves into a more or less +extensive collection, according to the time or penetration that has +been applied to the consideration of them. Where this process, +conducted as it is mechanically, so to speak, will end, cannot be +determined with certainty. Besides, the conceptions which we +discover in this haphazard manner present themselves by no means in +order and systematic unity, but are at last coupled together only +according to resemblances to each other, and arranged in series, +according to the quantity of their content, from the simpler to the +more complex--series which are anything but systematic, though not +altogether without a certain kind of method in their construction. + +Transcendental philosophy has the advantage, and moreover the +duty, of searching for its conceptions according to a principle; +because these conceptions spring pure and unmixed out of the +understanding as an absolute unity, and therefore must be connected +with each other according to one conception or idea. A connection of +this kind, however, furnishes us with a ready prepared rule, by +which its proper place may be assigned to every pure conception of +the understanding, and the completeness of the system of all be determined +a priori--both which would otherwise have been dependent on mere +choice or chance. + + + +SS 4. SECTION 1. Of defined above Use of understanding in General. + +The understanding was defined above only negatively, as a +non-sensuous faculty of cognition. Now, independently of +sensibility, we cannot possibly have any intuition; consequently, +the understanding is no faculty of intuition. But besides intuition +there is no other mode of cognition, except through conceptions; +consequently, the cognition of every, at least of every human, +understanding is a cognition through conceptions--not intuitive, but +discursive. All intuitions, as sensuous, depend on affections; +conceptions, therefore, upon functions. By the word function I +understand the unity of the act of arranging diverse representations +under one common representation. Conceptions, then, are based on the +spontaneity of thought, as sensuous intuitions are on the +receptivity of impressions. Now, the understanding cannot make any +other use of these conceptions than to judge by means of them. As no +representation, except an intuition, relates immediately to its +object, a conception never relates immediately to an object, but +only to some other representation thereof, be that an intuition or +itself a conception. A judgement, therefore, is the mediate +cognition of an object, consequently the representation of a +representation of it. In every judgement there is a conception which +applies to, and is valid for many other conceptions, and which among +these comprehends also a given representation, this last being +immediately connected with an object. For example, in the judgement-- +"All bodies are divisible," our conception of divisible applies to +various other conceptions; among these, however, it is here +particularly applied to the conception of body, and this conception +of body relates to certain phenomena which occur to us. These objects, +therefore, are mediately represented by the conception of +divisibility. All judgements, accordingly, are functions of unity in +our representations, inasmuch as, instead of an immediate, a higher +representation, which comprises this and various others, is used for +our cognition of the object, and thereby many possible cognitions +are collected into one. But we can reduce all acts of the +understanding to judgements, so that understanding may be +represented as the faculty of judging. For it is, according to what +has been said above, a faculty of thought. Now thought is cognition +by means of conceptions. But conceptions, as predicates of possible +judgements, relate to some representation of a yet undetermined +object. Thus the conception of body indicates something--for +example, metal--which can be cognized by means of that conception. +It is therefore a conception, for the reason alone that other +representations are contained under it, by means of which it can +relate to objects. It is therefore the predicate to a possible +judgement; for example: "Every metal is a body." All the functions +of the understanding therefore can be discovered, when we can +completely exhibit the functions of unity in judgements. And that this +may be effected very easily, the following section will show. + + + +SS 5. SECTION II. Of the Logical Function of the Understanding in + Judgements. + +If we abstract all the content of a judgement, and consider only the +intellectual form thereof, we find that the function of thought in +a judgement can be brought under four heads, of which each contains +three momenta. These may be conveniently represented in the +following table: + + 1 + Quantity of judgements + Universal + Particular + Singular + + 2 3 + Quality Relation + Affirmative Categorical + Negative Hypothetical + Infinite Disjunctive + + 4 + Modality + Problematical + Assertorical + Apodeictical + + +As this division appears to differ in some, though not essential +points, from the usual technique of logicians, the following +observations, for the prevention of otherwise possible +misunderstanding, will not be without their use. + +1. Logicians say, with justice, that in the use of judgements in +syllogisms, singular judgements may be treated like universal ones. +For, precisely because a singular judgement has no extent at all, +its predicate cannot refer to a part of that which is contained in +the conception of the subject and be excluded from the rest. The predicate +is valid for the whole conception just as if it were a general +conception, and had extent, to the whole of which the predicate +applied. On the other hand, let us compare a singular with a general +judgement, merely as a cognition, in regard to quantity. The +singular judgement relates to the general one, as unity to infinity, +and is therefore in itself essentially different. Thus, if we estimate +a singular judgement (judicium singulare) not merely according to +its intrinsic validity as a judgement, but also as a cognition +generally, according to its quantity in comparison with that of +other cognitions, it is then entirely different from a general +judgement (judicium commune), and in a complete table of the momenta +of thought deserves a separate place--though, indeed, this would not +be necessary in a logic limited merely to the consideration of the +use of judgements in reference to each other. + +2. In like manner, in transcendental logic, infinite must be +distinguished from affirmative judgements, although in general logic +they are rightly enough classed under affirmative. General logic +abstracts all content of the predicate (though it be negative), and +only considers whether the said predicate be affirmed or denied of +the subject. But transcendental logic considers also the worth or +content of this logical affirmation--an affirmation by means of a +merely negative predicate, and inquires how much the sum total of +our cognition gains by this affirmation. For example, if I say of +the soul, "It is not mortal"--by this negative judgement I should at +least ward off error. Now, by the proposition, "The soul is not +mortal," I have, in respect of the logical form, really affirmed, +inasmuch as I thereby place the soul in the unlimited sphere of +immortal beings. Now, because of the whole sphere of possible +existences, the mortal occupies one part, and the immortal the +other, neither more nor less is affirmed by the proposition than +that the soul is one among the infinite multitude of things which +remain over, when I take away the whole mortal part. But by this +proceeding we accomplish only this much, that the infinite sphere of +all possible existences is in so far limited that the mortal is +excluded from it, and the soul is placed in the remaining part of +the extent of this sphere. But this part remains, notwithstanding this +exception, infinite, and more and more parts may be taken away from +the whole sphere, without in the slightest degree thereby augmenting +or affirmatively determining our conception of the soul. These +judgements, therefore, infinite in respect of their logical extent, +are, in respect of the content of their cognition, merely +limitative; and are consequently entitled to a place in our +transcendental table of all the momenta of thought in judgements, +because the function of the understanding exercised by them may +perhaps be of importance in the field of its pure a priori cognition. + +3. All relations of thought in judgements are those (a) of the +predicate to the subject; (b) of the principle to its consequence; +(c) of the divided cognition and all the members of the division to +each other. In the first of these three classes, we consider only two +conceptions; in the second, two judgements; in the third, several +judgements in relation to each other. The hypothetical proposition, +"If perfect justice exists, the obstinately wicked are punished," +contains properly the relation to each other of two propositions, +namely, "Perfect justice exists," and "The obstinately wicked are +punished." Whether these propositions are in themselves true is a +question not here decided. Nothing is cogitated by means of this +judgement except a certain consequence. Finally, the disjunctive +judgement contains a relation of two or more propositions to each +other--a relation not of consequence, but of logical opposition, in +so far as the sphere of the one proposition excludes that of the other. +But it contains at the same time a relation of community, in so far +as all the propositions taken together fill up the sphere of the +cognition. The disjunctive judgement contains, therefore, the relation +of the parts of the whole sphere of a cognition, since the sphere of +each part is a complemental part of the sphere of the other, each +contributing to form the sum total of the divided cognition. Take, +for example, the proposition, "The world exists either through blind +chance, or through internal necessity, or through an external +cause." Each of these propositions embraces a part of the sphere of +our possible cognition as to the existence of a world; all of them +taken together, the whole sphere. To take the cognition out of one +of these spheres, is equivalent to placing it in one of the others; +and, on the other hand, to place it in one sphere is equivalent to +taking it out of the rest. There is, therefore, in a disjunctive +judgement a certain community of cognitions, which consists in this, +that they mutually exclude each other, yet thereby determine, as a +whole, the true cognition, inasmuch as, taken together, they make up +the complete content of a particular given cognition. And this is +all that I find necessary, for the sake of what follows, to remark +in this place. + +4. The modality of judgements is a quite peculiar function, with +this distinguishing characteristic, that it contributes nothing to +the content of a judgement (for besides quantity, quality, and relation, +there is nothing more that constitutes the content of a judgement), +but concerns itself only with the value of the copula in relation to +thought in general. Problematical judgements are those in which the +affirmation or negation is accepted as merely possible (ad libitum). +In the assertorical, we regard the proposition as real (true); in +the apodeictical, we look on it as necessary.* Thus the two judgements +(antecedens et consequens), the relation of which constitutes a +hypothetical judgement, likewise those (the members of the division) +in whose reciprocity the disjunctive consists, are only problematical. +In the example above given the proposition, "There exists perfect +justice," is not stated assertorically, but as an ad libitum +judgement, which someone may choose to adopt, and the consequence +alone is assertorical. Hence such judgements may be obviously false, +and yet, taken problematically, be conditions of our cognition of +the truth. Thus the proposition, "The world exists only by blind +chance," is in the disjunctive judgement of problematical import only: +that is to say, one may accept it for the moment, and it helps us +(like the indication of the wrong road among all the roads that one +can take) to find out the true proposition. The problematical +proposition is, therefore, that which expresses only logical +possibility (which is not objective); that is, it expresses a free +choice to admit the validity of such a proposition--a merely arbitrary +reception of it into the understanding. The assertorical speaks of +logical reality or truth; as, for example, in a hypothetical +syllogism, the antecedens presents itself in a problematical form in +the major, in an assertorical form in the minor, and it shows that +the proposition is in harmony with the laws of the understanding. The +apodeictical proposition cogitates the assertorical as determined by +these very laws of the understanding, consequently as affirming a +priori, and in this manner it expresses logical necessity. Now because +all is here gradually incorporated with the understanding--inasmuch +as in the first place we judge problematically; then accept +assertorically our judgement as true; lastly, affirm it as inseparably +united with the understanding, that is, as necessary and apodeictical-- +we may safely reckon these three functions of modality as so many +momenta of thought. + +[*Footnote: Just as if thought were in the first instance a function +of the understanding; in the second, of judgement; in the third, of +reason. A remark which will be explained in the sequel.] + + + +SS 6. SECTION III. Of the Pure Conceptions of the Understanding, or + Categories. + +General logic, as has been repeatedly said, makes abstraction of all +content of cognition, and expects to receive representations from some +other quarter, in order, by means of analysis, to convert them into +conceptions. On the contrary, transcendental logic has lying before +it the manifold content of a priori sensibility, which transcendental +aesthetic presents to it in order to give matter to the pure +conceptions of the understanding, without which transcendental logic +would have no content, and be therefore utterly void. Now space and +time contain an infinite diversity of determinations of pure a +priori intuition, but are nevertheless the condition of the mind's +receptivity, under which alone it can obtain representations of +objects, and which, consequently, must always affect the conception +of these objects. But the spontaneity of thought requires that this +diversity be examined after a certain manner, received into the +mind, and connected, in order afterwards to form a cognition out of +it. This Process I call synthesis. + +By the word synthesis, in its most general signification, I +understand the process of joining different representations to each +other and of comprehending their diversity in one cognition. This +synthesis is pure when the diversity is not given empirically but a +priori (as that in space and time). Our representations must be +given previously to any analysis of them; and no conceptions can +arise, quoad their content, analytically. But the synthesis of a +diversity (be it given a priori or empirically) is the first requisite +for the production of a cognition, which in its beginning, indeed, +may be crude and confused, and therefore in need of analysis--still, +synthesis is that by which alone the elements of our cognitions are +collected and united into a certain content, consequently it is the +first thing on which we must fix our attention, if we wish to +investigate the origin of our knowledge. + +Synthesis, generally speaking, is, as we shall afterwards see, the +mere operation of the imagination--a blind but indispensable +function of the soul, without which we should have no cognition +whatever, but of the working of which we are seldom even conscious. +But to reduce this synthesis to conceptions is a function of the +understanding, by means of which we attain to cognition, in the proper +meaning of the term. + +Pure synthesis, represented generally, gives us the pure +conception of the understanding. But by this pure synthesis, I mean +that which rests upon a basis of a priori synthetical unity. Thus, +our numeration (and this is more observable in large numbers) is a +synthesis according to conceptions, because it takes place according +to a common basis of unity (for example, the decade). By means of this +conception, therefore, the unity in the synthesis of the manifold +becomes necessary. + +By means of analysis different representations are brought under one +conception--an operation of which general logic treats. On the other +hand, the duty of transcendental logic is to reduce to conceptions, +not representations, but the pure synthesis of representations. The +first thing which must be given to us for the sake of the a priori +cognition of all objects, is the diversity of the pure intuition; +the synthesis of this diversity by means of the imagination is the +second; but this gives, as yet, no cognition. The conceptions which +give unity to this pure synthesis, and which consist solely in the +representation of this necessary synthetical unity, furnish the +third requisite for the cognition of an object, and these +conceptions are given by the understanding. + +The same function which gives unity to the different +representation in a judgement, gives also unity to the mere +synthesis of different representations in an intuition; and this unity +we call the pure conception of the understanding. Thus, the same +understanding, and by the same operations, whereby in conceptions, +by means of analytical unity, it produced the logical form of a +judgement, introduces, by means of the synthetical unity of the +manifold in intuition, a transcendental content into its +representations, on which account they are called pure conceptions +of the understanding, and they apply a priori to objects, a result +not within the power of general logic. + +In this manner, there arise exactly so many pure conceptions of +the understanding, applying a priori to objects of intuition in +general, as there are logical functions in all possible judgements. +For there is no other function or faculty existing in the +understanding besides those enumerated in that table. These +conceptions we shall, with Aristotle, call categories, our purpose +being originally identical with his, notwithstanding the great +difference in the execution. + + TABLE OF THE CATEGORIES + + 1 2 + + Of Quantity Of Quality + Unity Reality + Plurality Negation + Totality Limitation + + 3 + Of Relation + Of Inherence and Subsistence (substantia et accidens) + Of Causality and Dependence (cause and effect) + Of Community (reciprocity between the agent and patient) + + 4 + Of Modality + Possibility--Impossibility + Existence--Non-existence + Necessity--Contingence + + +This, then, is a catalogue of all the originally pure conceptions of +the synthesis which the understanding contains a priori, and these +conceptions alone entitle it to be called a pure understanding; +inasmuch as only by them it can render the manifold of intuition +conceivable, in other words, think an object of intuition. This +division is made systematically from a common principle, namely the +faculty of judgement (which is just the same as the power of thought), +and has not arisen rhapsodically from a search at haphazard after pure +conceptions, respecting the full number of which we never could be +certain, inasmuch as we employ induction alone in our search, +without considering that in this way we can never understand wherefore +precisely these conceptions, and none others, abide in the pure +understanding. It was a design worthy of an acute thinker like +Aristotle, to search for these fundamental conceptions. Destitute, +however, of any guiding principle, he picked them up just as they +occurred to him, and at first hunted out ten, which he called +categories (predicaments). Afterwards be believed that he had +discovered five others, which were added under the name of post +predicaments. But his catalogue still remained defective. Besides, +there are to be found among them some of the modes of pure sensibility +(quando, ubi, situs, also prius, simul), and likewise an empirical +conception (motus)--which can by no means belong to this +genealogical register of the pure understanding. Moreover, there are +deduced conceptions (actio, passio) enumerated among the original +conceptions, and, of the latter, some are entirely wanting. + +With regard to these, it is to be remarked, that the categories, +as the true primitive conceptions of the pure understanding, have also +their pure deduced conceptions, which, in a complete system of +transcendental philosophy, must by no means be passed over; though +in a merely critical essay we must be contented with the simple +mention of the fact. + +Let it be allowed me to call these pure, but deduced conceptions +of the understanding, the predicables of the pure understanding, in +contradistinction to predicaments. If we are in possession of the +original and primitive, the deduced and subsidiary conceptions can +easily be added, and the genealogical tree of the understanding +completely delineated. As my present aim is not to set forth a +complete system, but merely the principles of one, I reserve this task +for another time. It may be easily executed by any one who will +refer to the ontological manuals, and subordinate to the category of +causality, for example, the predicables of force, action, passion; +to that of community, those of presence and resistance; to the +categories of modality, those of origination, extinction, change; +and so with the rest. The categories combined with the modes of pure +sensibility, or with one another, afford a great number of deduced +a priori conceptions; a complete enumeration of which would be a +useful and not unpleasant, but in this place a perfectly +dispensable, occupation. + +I purposely omit the definitions of the categories in this treatise. +I shall analyse these conceptions only so far as is necessary for +the doctrine of method, which is to form a part of this critique. In +a system of pure reason, definitions of them would be with justice +demanded of me, but to give them here would only bide from our view +the main aim of our investigation, at the same time raising doubts +and objections, the consideration of which, without injustice to our +main purpose, may be very well postponed till another opportunity. +Meanwhile, it ought to be sufficiently clear, from the little we +have already said on this subject, that the formation of a complete +vocabulary of pure conceptions, accompanied by all the requisite +explanations, is not only a possible, but an easy undertaking. The +compartments already exist; it is only necessary to fill them up; +and a systematic topic like the present, indicates with perfect +precision the proper place to which each conception belongs, while +it readily points out any that have not yet been filled up. + + + +SS 7. + +Our table of the categories suggests considerations of some +importance, which may perhaps have significant results in regard to +the scientific form of all rational cognitions. For, that this table +is useful in the theoretical part of philosophy, nay, indispensable +for the sketching of the complete plan of a science, so far as that +science rests upon conceptions a priori, and for dividing it +mathematically, according to fixed principles, is most manifest from +the fact that it contains all the elementary conceptions of the +understanding, nay, even the form of a system of these in the +understanding itself, and consequently indicates all the momenta, +and also the internal arrangement of a projected speculative +science, as I have elsewhere shown. [Footnote: In the +Metaphysical Principles of Natural Science.] Here follow some of these +observations. + +I. This table, which contains four classes of conceptions of the +understanding, may, in the first instance, be divided into two +classes, the first of which relates to objects of intuition--pure as +well as empirical; the second, to the existence of these objects, +either in relation to one another, or to the understanding. + +The former of these classes of categories I would entitle the +mathematical, and the latter the dynamical categories. The former, +as we see, has no correlates; these are only to be found in the second +class. This difference must have a ground in the nature of the human +understanding. + +II. The number of the categories in each class is always the same, +namely, three--a fact which also demands some consideration, because +in all other cases division a priori through conceptions is +necessarily dichotomy. It is to be added, that the third category in +each triad always arises from the combination of the second with the +first. + +Thus totality is nothing else but plurality contemplated as unity; +limitation is merely reality conjoined with negation; community is +the causality of a substance, reciprocally determining, and determined +by other substances; and finally, necessity is nothing but +existence, which is given through the possibility itself. Let it not +be supposed, however, that the third category is merely a deduced, +and not a primitive conception of the pure understanding. For the +conjunction of the first and second, in order to produce the third +conception, requires a particular function of the understanding, which +is by no means identical with those which are exercised in the first +and second. Thus, the conception of a number (which belongs to the +category of totality) is not always possible, where the conceptions +of multitude and unity exist (for example, in the representation of +the infinite). Or, if I conjoin the conception of a cause with that +of a substance, it does not follow that the conception of influence, +that is, how one substance can be the cause of something in another +substance, will be understood from that. Thus it is evident that a +particular act of the understanding is here necessary; and so in the +other instances. + +III. With respect to one category, namely, that of community, +which is found in the third class, it is not so easy as with the +others to detect its accordance with the form of the disjunctive +judgement which corresponds to it in the table of the logical +functions. + +In order to assure ourselves of this accordance, we must observe +that in every disjunctive judgement, the sphere of the judgement (that +is, the complex of all that is contained in it) is represented as a +whole divided into parts; and, since one part cannot be contained in +the other, they are cogitated as co-ordinated with, not subordinated +to each other, so that they do not determine each other +unilaterally, as in a linear series, but reciprocally, as in an +aggregate--(if one member of the division is posited, all the rest +are excluded; and conversely). + +Now a like connection is cogitated in a whole of things; for one +thing is not subordinated, as effect, to another as cause of its +existence, but, on the contrary, is co-ordinated contemporaneously +and reciprocally, as a cause in relation to the determination of the +others (for example, in a body--the parts of which mutually attract +and repel each other). And this is an entirely different kind of +connection from that which we find in the mere relation of the cause +to the effect (the principle to the consequence), for in such a +connection the consequence does not in its turn determine the +principle, and therefore does not constitute, with the latter, a +whole--just as the Creator does not with the world make up a whole. +The process of understanding by which it represents to itself the +sphere of a divided conception, is employed also when we think of a +thing as divisible; and in the same manner as the members of the +division in the former exclude one another, and yet are connected in +one sphere, so the understanding represents to itself the parts of +the latter, as having--each of them--an existence (as substances), +independently of the others, and yet as united in one whole. + + + +SS 8. + +In the transcendental philosophy of the ancients there exists one more +leading division, which contains pure conceptions of the understanding, +and which, although not numbered among the categories, ought, according +to them, as conceptions a priori, to be valid of objects. But in this +case they would augment the number of the categories; which cannot be. +These are set forth in the proposition, so renowned among the +schoolmen--"Quodlibet ens est UNUM, VERUM, BONUM." Now, though the +inferences from this principle were mere tautological propositions, and +though it is allowed only by courtesy to retain a place in modern +metaphysics, yet a thought which maintained itself for such a length of +time, however empty it seems to be, deserves an investigation of its +origin, and justifies the conjecture that it must be grounded in some +law of the understanding, which, as is often the case, has only been +erroneously interpreted. These pretended transcendental predicates are, +in fact, nothing but logical requisites and criteria of all cognition +of objects, and they employ, as the basis for this cognition, the +categories of quantity, namely, unity, plurality, and totality. But +these, which must be taken as material conditions, that is, as +belonging to the possibility of things themselves, they employed merely +in a formal signification, as belonging to the logical requisites of +all cognition, and yet most unguardedly changed these criteria of +thought into properties of objects, as things in themselves. Now, in +every cognition of an object, there is unity of conception, which may +be called qualitative unity, so far as by this term we understand only +the unity in our connection of the manifold; for example, unity of the +theme in a play, an oration, or a story. Secondly, there is truth in +respect of the deductions from it. The more true deductions we have +from a given conception, the more criteria of its objective reality. +This we might call the qualitative plurality of characteristic marks, +which belong to a conception as to a common foundation, but are not +cogitated as a quantity in it. Thirdly, there is perfection--which +consists in this, that the plurality falls back upon the unity of the +conception, and accords completely with that conception and with no +other. This we may denominate qualitative completeness. Hence it is +evident that these logical criteria of the possibility of cognition are +merely the three categories of quantity modified and transformed to +suit an unauthorized manner of applying them. That is to say, the three +categories, in which the unity in the production of the quantum must be +homogeneous throughout, are transformed solely with a view to the +connection of heterogeneous parts of cognition in one act of +consciousness, by means of the quality of the cognition, which is the +principle of that connection. Thus the criterion of the possibility of +a conception (not of its object) is the definition of it, in which the +unity of the conception, the truth of all that may be immediately +deduced from it, and finally, the completeness of what has been thus +deduced, constitute the requisites for the reproduction of the whole +conception. Thus also, the criterion or test of an hypothesis is the +intelligibility of the received principle of explanation, or its unity +(without help from any subsidiary hypothesis)--the truth of our +deductions from it (consistency with each other and with +experience)--and lastly, the completeness of the principle of the +explanation of these deductions, which refer to neither more nor less +than what was admitted in the hypothesis, restoring analytically and a +posteriori, what was cogitated synthetically and a priori. By the +conceptions, therefore, of unity, truth, and perfection, we have made +no addition to the transcendental table of the categories, which is +complete without them. We have, on the contrary, merely employed the +three categories of quantity, setting aside their application to +objects of experience, as general logical laws of the consistency of +cognition with itself. + + + +CHAPTER II Of the Deduction of the Pure Conceptions of the Understanding. + +SS 9. SECTION I Of the Principles of a Transcendental Deduction + in general. + +Teachers of jurisprudence, when speaking of rights and claims, +distinguish in a cause the question of right (quid juris) from the +question of fact (quid facti), and while they demand proof of both, +they give to the proof of the former, which goes to establish right +or claim in law, the name of deduction. Now we make use of a great +number of empirical conceptions, without opposition from any one; and +consider ourselves, even without any attempt at deduction, justified +in attaching to them a sense, and a supposititious signification, +because we have always experience at hand to demonstrate their +objective reality. There exist also, however, usurped conceptions, +such as fortune, fate, which circulate with almost universal +indulgence, and yet are occasionally challenged by the question, "quid +juris?" In such cases, we have great difficulty in discovering any +deduction for these terms, inasmuch as we cannot produce any +manifest ground of right, either from experience or from reason, on +which the claim to employ them can be founded. + +Among the many conceptions, which make up the very variegated web of +human cognition, some are destined for pure use a priori, +independent of all experience; and their title to be so employed +always requires a deduction, inasmuch as, to justify such use of them, +proofs from experience are not sufficient; but it is necessary to know +how these conceptions can apply to objects without being derived +from experience. I term, therefore, an examination of the manner in +which conceptions can apply a priori to objects, the transcendental +deduction of conceptions, and I distinguish it from the empirical +deduction, which indicates the mode in which conception is obtained +through experience and reflection thereon; consequently, does not +concern itself with the right, but only with the fact of our obtaining +conceptions in such and such a manner. We have already seen that we +are in possession of two perfectly different kinds of conceptions, +which nevertheless agree with each other in this, that they both apply +to objects completely a priori. These are the conceptions of space +and time as forms of sensibility, and the categories as pure conceptions +of the understanding. To attempt an empirical deduction of either of +these classes would be labour in vain, because the distinguishing +characteristic of their nature consists in this, that they apply to +their objects, without having borrowed anything from experience +towards the representation of them. Consequently, if a deduction of +these conceptions is necessary, it must always be transcendental. + +Meanwhile, with respect to these conceptions, as with respect to all +our cognition, we certainly may discover in experience, if not the +principle of their possibility, yet the occasioning causes of their +production. It will be found that the impressions of sense give the +first occasion for bringing into action the whole faculty of +cognition, and for the production of experience, which contains two +very dissimilar elements, namely, a matter for cognition, given by +the senses, and a certain form for the arrangement of this matter, +arising out of the inner fountain of pure intuition and thought; and +these, on occasion given by sensuous impressions, are called into exercise +and produce conceptions. Such an investigation into the first efforts +of our faculty of cognition to mount from particular perceptions to +general conceptions is undoubtedly of great utility; and we have to +thank the celebrated Locke for having first opened the way for this +inquiry. But a deduction of the pure a priori conceptions of course +never can be made in this way, seeing that, in regard to their +future employment, which must be entirely independent of experience, +they must have a far different certificate of birth to show from +that of a descent from experience. This attempted physiological +derivation, which cannot properly be called deduction, because it +relates merely to a quaestio facti, I shall entitle an explanation +of the possession of a pure cognition. It is therefore manifest that +there can only be a transcendental deduction of these conceptions +and by no means an empirical one; also, that all attempts at an +empirical deduction, in regard to pure a priori conceptions, are vain, +and can only be made by one who does not understand the altogether +peculiar nature of these cognitions. + +But although it is admitted that the only possible deduction of pure +a priori cognition is a transcendental deduction, it is not, for +that reason, perfectly manifest that such a deduction is absolutely +necessary. We have already traced to their sources the conceptions +of space and time, by means of a transcendental deduction, and we have +explained and determined their objective validity a priori. +Geometry, nevertheless, advances steadily and securely in the province +of pure a priori cognitions, without needing to ask from philosophy +any certificate as to the pure and legitimate origin of its +fundamental conception of space. But the use of the conception in this +science extends only to the external world of sense, the pure form +of the intuition of which is space; and in this world, therefore, +all geometrical cognition, because it is founded upon a priori +intuition, possesses immediate evidence, and the objects of this +cognition are given a priori (as regards their form) in intuition by +and through the cognition itself. With the pure conceptions of +understanding, on the contrary, commences the absolute necessity of +seeking a transcendental deduction, not only of these conceptions +themselves, but likewise of space, because, inasmuch as they make +affirmations concerning objects not by means of the predicates of +intuition and sensibility, but of pure thought a priori, they apply +to objects without any of the conditions of sensibility. Besides, not +being founded on experience, they are not presented with any object +in a priori intuition upon which, antecedently to experience, they +might base their synthesis. Hence results, not only doubt as to the +objective validity and proper limits of their use, but that even our +conception of space is rendered equivocal; inasmuch as we are very +ready with the aid of the categories, to carry the use of this +conception beyond the conditions of sensuous intuition--and, for +this reason, we have already found a transcendental deduction of it +needful. The reader, then, must be quite convinced of the absolute +necessity of a transcendental deduction, before taking a single step +in the field of pure reason; because otherwise he goes to work +blindly, and after he has wondered about in all directions, returns +to the state of utter ignorance from which he started. He ought, +moreover, clearly to recognize beforehand the unavoidable difficulties +in his undertaking, so that he may not afterwards complain of the +obscurity in which the subject itself is deeply involved, or become +too soon impatient of the obstacles in his path; because we have a +choice of only two things--either at once to give up all pretensions +to knowledge beyond the limits of possible experience, or to bring +this critical investigation to completion. + +We have been able, with very little trouble, to make it +comprehensible how the conceptions of space and time, although a +priori cognitions, must necessarily apply to external objects, and +render a synthetical cognition of these possible, independently of +all experience. For inasmuch as only by means of such pure form of +sensibility an object can appear to us, that is, be an object of +empirical intuition, space and time are pure intuitions, which contain +a priori the condition of the possibility of objects as phenomena, +and an a priori synthesis in these intuitions possesses objective +validity. + +On the other hand, the categories of the understanding do not +represent the conditions under which objects are given to us in +intuition; objects can consequently appear to us without necessarily +connecting themselves with these, and consequently without any +necessity binding on the understanding to contain a priori the +conditions of these objects. Thus we find ourselves involved in a +difficulty which did not present itself in the sphere of +sensibility, that is to say, we cannot discover how the subjective +conditions of thought can have objective validity, in other words, +can become conditions of the possibility of all cognition of objects; +for phenomena may certainly be given to us in intuition without any +help from the functions of the understanding. Let us take, for +example, the conception of cause, which indicates a peculiar kind of +synthesis, namely, that with something, A, something entirely +different, B, is connected according to a law. It is not a priori +manifest why phenomena should contain anything of this kind (we are +of course debarred from appealing for proof to experience, for the +objective validity of this conception must be demonstrated a +priori), and it hence remains doubtful a priori, whether such a +conception be not quite void and without any corresponding object +among phenomena. For that objects of sensuous intuition must +correspond to the formal conditions of sensibility existing a priori +in the mind is quite evident, from the fact that without these they +could not be objects for us; but that they must also correspond to +the conditions which understanding requires for the synthetical unity +of thought is an assertion, the grounds for which are not so easily +to be discovered. For phenomena might be so constituted as not to +correspond to the conditions of the unity of thought; and all things +might lie in such confusion that, for example, nothing could be met +with in the sphere of phenomena to suggest a law of synthesis, and +so correspond to the conception of cause and effect; so that this +conception would be quite void, null, and without significance. Phenomena +would nevertheless continue to present objects to our intuition; for +mere intuition does not in any respect stand in need of the functions +of thought. + +If we thought to free ourselves from the labour of these +investigations by saying: "Experience is constantly offering us +examples of the relation of cause and effect in phenomena, and +presents us with abundant opportunity of abstracting the conception +of cause, and so at the same time of corroborating the objective validity +of this conception"; we should in this case be overlooking the fact, +that the conception of cause cannot arise in this way at all; that, +on the contrary, it must either have an a priori basis in the +understanding, or be rejected as a mere chimera. For this conception +demands that something, A, should be of such a nature that something +else, B, should follow from it necessarily, and according to an +absolutely universal law. We may certainly collect from phenomena a +law, according to which this or that usually happens, but the +element of necessity is not to be found in it. Hence it is evident +that to the synthesis of cause and effect belongs a dignity, which +is utterly wanting in any empirical synthesis; for it is no mere +mechanical synthesis, by means of addition, but a dynamical one; +that is to say, the effect is not to be cogitated as merely annexed +to the cause, but as posited by and through the cause, and resulting +from it. The strict universality of this law never can be a +characteristic of empirical laws, which obtain through induction +only a comparative universality, that is, an extended range of +practical application. But the pure conceptions of the understanding +would entirely lose all their peculiar character, if we treated them +merely as the productions of experience. + + + +SS 10. Transition to the Transcendental Deduction of the + Categories. + +There are only two possible ways in which synthetical representation +and its objects can coincide with and relate necessarily to each +other, and, as it were, meet together. Either the object alone makes +the representation possible, or the representation alone makes the +object possible. In the former case, the relation between them is only +empirical, and an a priori representation is impossible. And this is +the case with phenomena, as regards that in them which is referable +to mere sensation. In the latter case--although representation alone +(for of its causality, by means of the will, we do not here speak) +does not produce the object as to its existence, it must nevertheless +be a priori determinative in regard to the object, if it is only by +means of the representation that we can cognize anything as an object. +Now there are only two conditions of the possibility of a cognition +of objects; firstly, intuition, by means of which the object, though +only as phenomenon, is given; secondly, conception, by means of which +the object which corresponds to this intuition is thought. But it is +evident from what has been said on aesthetic that the first condition, +under which alone objects can be intuited, must in fact exist, as a +formal basis for them, a priori in the mind. With this formal +condition of sensibility, therefore, all phenomena necessarily +correspond, because it is only through it that they can be phenomena +at all; that is, can be empirically intuited and given. Now the +question is whether there do not exist, a priori in the mind, +conceptions of understanding also, as conditions under which alone +something, if not intuited, is yet thought as object. If this question +be answered in the affirmative, it follows that all empirical +cognition of objects is necessarily conformable to such conceptions, +since, if they are not presupposed, it is impossible that anything +can be an object of experience. Now all experience contains, besides +the intuition of the senses through which an object is given, a conception +also of an object that is given in intuition. Accordingly, conceptions +of objects in general must lie as a priori conditions at the +foundation of all empirical cognition; and consequently, the objective +validity of the categories, as a priori conceptions, will rest upon +this, that experience (as far as regards the form of thought) is +possible only by their means. For in that case they apply +necessarily and a priori to objects of experience, because only +through them can an object of experience be thought. + +The whole aim of the transcendental deduction of all a priori +conceptions is to show that these conceptions are a priori +conditions of the possibility of all experience. Conceptions which +afford us the objective foundation of the possibility of experience +are for that very reason necessary. But the analysis of the +experiences in which they are met with is not deduction, but only an +illustration of them, because from experience they could never +derive the attribute of necessity. Without their original +applicability and relation to all possible experience, in which all +objects of cognition present themselves, the relation of the +categories to objects, of whatever nature, would be quite +incomprehensible. + +The celebrated Locke, for want of due reflection on these points, +and because he met with pure conceptions of the understanding in +experience, sought also to deduce them from experience, and yet +proceeded so inconsequently as to attempt, with their aid, to arrive +it cognitions which lie far beyond the limits of all experience. David +Hume perceived that, to render this possible, it was necessary that +the conceptions should have an a priori origin. But as he could not +explain how it was possible that conceptions which are not connected +with each other in the understanding must nevertheless be thought as +necessarily connected in the object--and it never occurred to him that +the understanding itself might, perhaps, by means of these +conceptions, be the author of the experience in which its objects were +presented to it--he was forced to drive these conceptions from +experience, that is, from a subjective necessity arising from repeated +association of experiences erroneously considered to be objective-- +in one word, from habit. But he proceeded with perfect consequence +and declared it to be impossible, with such conceptions and the principles +arising from them, to overstep the limits of experience. The empirical +derivation, however, which both of these philosophers attributed to +these conceptions, cannot possibly be reconciled with the fact that +we do possess scientific a priori cognitions, namely, those of pure +mathematics and general physics. + +The former of these two celebrated men opened a wide door to +extravagance--(for if reason has once undoubted right on its side, +it will not allow itself to be confined to set limits, by vague +recommendations of moderation); the latter gave himself up entirely +to scepticism--a natural consequence, after having discovered, as he +thought, that the faculty of cognition was not trustworthy. We now +intend to make a trial whether it be not possible safely to conduct +reason between these two rocks, to assign her determinate limits, +and yet leave open for her the entire sphere of her legitimate +activity. + +I shall merely premise an explanation of what the categories are. +They are conceptions of an object in general, by means of which its +intuition is contemplated as determined in relation to one of the +logical functions of judgement. The following will make this plain. +The function of the categorical judgement is that of the relation of +subject to predicate; for example, in the proposition: "All bodies +are divisible." But in regard to the merely logical use of the +understanding, it still remains undetermined to which Of these two +conceptions belongs the function Of subject and to which that of +predicate. For we could also say: "Some divisible is a body." But +the category of substance, when the conception of a body is brought +under it, determines that; and its empirical intuition in experience +must be contemplated always as subject and never as mere predicate. +And so with all the other categories. + + + +SS 11. SECTION II Transcendental Deduction of the pure Conceptions of + the Understanding. + +Of the Possibility of a Conjunction of the manifold representations +given by Sense. + +The manifold content in our representations can be given in an +intuition which is merely sensuous--in other words, is nothing but +susceptibility; and the form of this intuition can exist a priori in +our faculty of representation, without being anything else but the +mode in which the subject is affected. But the conjunction +(conjunctio) of a manifold in intuition never can be given us by the +senses; it cannot therefore be contained in the pure form of +sensuous intuition, for it is a spontaneous act of the faculty of +representation. And as we must, to distinguish it from sensibility, +entitle this faculty understanding; so all conjunction whether +conscious or unconscious, be it of the manifold in intuition, sensuous +or non-sensuous, or of several conceptions--is an act of the +understanding. To this act we shall give the general appellation of +synthesis, thereby to indicate, at the same time, that we cannot +represent anything as conjoined in the object without having +previously conjoined it ourselves. Of all mental notions, that of +conjunction is the only one which cannot be given through objects, +but can be originated only by the subject itself, because it is an +act of its purely spontaneous activity. The reader will easily enough +perceive that the possibility of conjunction must be grounded in the +very nature of this act, and that it must be equally valid for all +conjunction, and that analysis, which appears to be its contrary, +must, nevertheless, always presuppose it; for where the +understanding has not previously conjoined, it cannot dissect or +analyse, because only as conjoined by it, must that which is to be +analysed have been given to our faculty of representation. + +But the conception of conjunction includes, besides the conception +of the manifold and of the synthesis of it, that of the unity of it +also. Conjunction is the representation of the synthetical unity of +the manifold.* This idea of unity, therefore, cannot arise out of that +of conjunction; much rather does that idea, by combining itself with +the representation of the manifold, render the conception of +conjunction possible. This unity, which a priori precedes all +conceptions of conjunction, is not the category of unity (SS 6); for +all the categories are based upon logical functions of judgement, +and in these functions we already have conjunction, and consequently +unity of given conceptions. It is therefore evident that the +category of unity presupposes conjunction. We must therefore look +still higher for this unity (as qualitative, SS 8), in that, namely, +which contains the ground of the unity of diverse conceptions in +judgements, the ground, consequently, of the possibility of the +existence of the understanding, even in regard to its logical use. + +[*Footnote: Whether the representations are in themselves identical, +and consequently whether one can be thought analytically by means of +and through the other, is a question which we need not at present +consider. Our Consciousness of the one, when we speak of the manifold, +is always distinguishable from our consciousness of the other; and +it is only respecting the synthesis of this (possible) consciousness +that we here treat.] + + + +SS 12. Of the Originally Synthetical Unity of Apperception. + +The "I think" must accompany all my representations, for otherwise +something would be represented in me which could not be thought; in +other words, the representation would either be impossible, or at +least be, in relation to me, nothing. That representation which can +be given previously to all thought is called intuition. All the diversity +or manifold content of intuition, has, therefore, a necessary relation +to the "I think," in the subject in which this diversity is found. +But this representation, "I think," is an act of spontaneity; that +is to say, it cannot be regarded as belonging to mere sensibility. +I call it pure apperception, in order to distinguish it from empirical; +or primitive apperception, because it is self-consciousness which, +whilst it gives birth to the representation "I think," must necessarily +be capable of accompanying all our representations. It is in all acts +of consciousness one and the same, and unaccompanied by it, no +representation can exist for me. The unity of this apperception I call +the transcendental unity of self-consciousness, in order to indicate +the possibility of a priori cognition arising from it. For the +manifold representations which are given in an intuition would not +all of them be my representations, if they did not all belong to one +self-consciousness, that is, as my representations (even although I +am not conscious of them as such), they must conform to the condition +under which alone they can exist together in a common +self-consciousness, because otherwise they would not all without +exception belong to me. From this primitive conjunction follow many +important results. + +For example, this universal identity of the apperception of the +manifold given in intuition contains a synthesis of representations +and is possible only by means of the consciousness of this +synthesis. For the empirical consciousness which accompanies different +representations is in itself fragmentary and disunited, and without +relation to the identity of the subject. This relation, then, does +not exist because I accompany every representation with consciousness, +but because I join one representation to another, and am conscious +of the synthesis of them. Consequently, only because I can connect +a variety of given representations in one consciousness, is it +possible that I can represent to myself the identity of +consciousness in these representations; in other words, the analytical +unity of apperception is possible only under the presupposition of +a synthetical unity.* The thought, "These representations given in +intuition belong all of them to me," is accordingly just the same +as, "I unite them in one self-consciousness, or can at least so +unite them"; and although this thought is not itself the consciousness +of the synthesis of representations, it presupposes the possibility +of it; that is to say, for the reason alone that I can comprehend the +variety of my representations in one consciousness, do I call them +my representations, for otherwise I must have as many-coloured and +various a self as are the representations of which I am conscious. +Synthetical unity of the manifold in intuitions, as given a priori, +is therefore the foundation of the identity of apperception itself, +which antecedes a priori all determinate thought. But the conjunction +of representations into a conception is not to be found in objects +themselves, nor can it be, as it were, borrowed from them and taken +up into the understanding by perception, but it is on the contrary +an operation of the understanding itself, which is nothing more than +the faculty of conjoining a priori and of bringing the variety of +given representations under the unity of apperception. This +principle is the highest in all human cognition. + +[*Footnote: All general conceptions--as such--depend, for their existence, +on the analytical unity of consciousness. For example, when I think +of red in general, I thereby think to myself a property which (as a +characteristic mark) can be discovered somewhere, or can be united +with other representations; consequently, it is only by means of a +forethought possible synthetical unity that I can think to myself +the analytical. A representation which is cogitated as common to +different representations, is regarded as belonging to such as, +besides this common representation, contain something different; +consequently it must be previously thought in synthetical unity with +other although only possible representations, before I can think in +it the analytical unity of consciousness which makes it a conceptas +communis. And thus the synthetical unity of apperception is the +highest point with which we must connect every operation of the +understanding, even the whole of logic, and after it our +transcendental philosophy; indeed, this faculty is the understanding +itself.] + +This fundamental principle of the necessary unity of apperception is +indeed an identical, and therefore analytical, proposition; but it +nevertheless explains the necessity for a synthesis of the manifold +given in an intuition, without which the identity of +self-consciousness would be incogitable. For the ego, as a simple +representation, presents us with no manifold content; only in +intuition, which is quite different from the representation ego, can +it be given us, and by means of conjunction it is cogitated in one +self-consciousness. An understanding, in which all the manifold should +be given by means of consciousness itself, would be intuitive; our +understanding can only think and must look for its intuition to sense. +I am, therefore, conscious of my identical self, in relation to all +the variety of representations given to me in an intuition, because +I call all of them my representations. In other words, I am +conscious myself of a necessary a priori synthesis of my +representations, which is called the original synthetical unity of +apperception, under which rank all the representations presented to +me, but that only by means of a synthesis. + + + +SS 13. The Principle of the Synthetical Unity of Apperception is + the highest Principle of all exercise of the Understanding. + +The supreme principle of the possibility of all intuition in +relation to sensibility was, according to our transcendental +aesthetic, that all the manifold in intuition be subject to the formal +conditions of space and time. The supreme principle of the possibility +of it in relation to the understanding is that all the manifold in +it be subject to conditions of the originally synthetical unity or +apperception.* To the former of these two principles are subject all +the various representations of intuition, in so far as they are +given to us; to the latter, in so far as they must be capable of +conjunction in one consciousness; for without this nothing can be +thought or cognized, because the given representations would not +have in common the act Of the apperception "I think" and therefore +could not be connected in one self-consciousness. + +[*Footnote: Space and time, and all portions thereof, are intuitions; +consequently are, with a manifold for their content, single +representations. (See the Transcendental Aesthetic.) Consequently, +they are not pure conceptions, by means of which the same +consciousness is found in a great number of representations; but, on +the contrary, they are many representations contained in one, the +consciousness of which is, so to speak, compounded. The unity of +consciousness is nevertheless synthetical and, therefore, primitive. +From this peculiar character of consciousness follow many important +consequences. (See SS 21.)] + +Understanding is, to speak generally, the faculty Of cognitions. +These consist in the determined relation of given representation to +an object. But an object is that, in the conception of which the manifold +in a given intuition is united. Now all union of representations +requires unity of consciousness in the synthesis of them. +Consequently, it is the unity of consciousness alone that +constitutes the possibility of representations relating to an +object, and therefore of their objective validity, and of their +becoming cognitions, and consequently, the possibility of the +existence of the understanding itself. + +The first pure cognition of understanding, then, upon which is +founded all its other exercise, and which is at the same time +perfectly independent of all conditions of mere sensuous intuition, +is the principle of the original synthetical unity of apperception. +Thus the mere form of external sensuous intuition, namely, space, +affords us, per se, no cognition; it merely contributes the manifold +in a priori intuition to a possible cognition. But, in order to +cognize something in space (for example, a line), I must draw it, +and thus produce synthetically a determined conjunction of the given +manifold, so that the unity of this act is at the same time the +unity of consciousness (in the conception of a line), and by this +means alone is an object (a determinate space) cognized. The +synthetical unity of consciousness is, therefore, an objective +condition of all cognition, which I do not merely require in order +to cognize an object, but to which every intuition must necessarily +be subject, in order to become an object for me; because in any other +way, and without this synthesis, the manifold in intuition could not +be united in one consciousness. + +This proposition is, as already said, itself analytical, although it +constitutes the synthetical unity, the condition of all thought; for +it states nothing more than that all my representations in any given +intuition must be subject to the condition which alone enables me to +connect them, as my representation with the identical self, and so +to unite them synthetically in one apperception, by means of the +general expression, "I think." + +But this principle is not to be regarded as a principle for every +possible understanding, but only for the understanding by means of +whose pure apperception in the thought I am, no manifold content is +given. The understanding or mind which contained the manifold in +intuition, in and through the act itself of its own +self-consciousness, in other words, an understanding by and in the +representation of which the objects of the representation should at +the same time exist, would not require a special act of synthesis of +the manifold as the condition of the unity of its consciousness, an +act of which the human understanding, which thinks only and cannot +intuite, has absolute need. But this principle is the first +principle of all the operations of our understanding, so that we +cannot form the least conception of any other possible +understanding, either of one such as should be itself intuition, or +possess a sensuous intuition, but with forms different from those of +space and time. + + + +SS 14. What Objective Unity of Self-consciousness is. + +It is by means of the transcendental unity of apperception that +all the manifold, given in an intuition is united into a conception +of the object. On this account it is called objective, and must be +distinguished from the subjective unity of consciousness, which is +a determination of the internal sense, by means of which the said +manifold in intuition is given empirically to be so united. Whether +I can be empirically conscious of the manifold as coexistent or as +successive, depends upon circumstances, or empirical conditions. Hence +the empirical unity of consciousness by means of association of +representations, itself relates to a phenomenal world and is wholly +contingent. On the contrary, the pure form of intuition in time, +merely as an intuition, which contains a given manifold, is subject +to the original unity of consciousness, and that solely by means of +the necessary relation of the manifold in intuition to the "I think," +consequently by means of the pure synthesis of the understanding, +which lies a priori at the foundation of all empirical synthesis. +The transcendental unity of apperception is alone objectively valid; +the empirical which we do not consider in this essay, and which is +merely a unity deduced from the former under given conditions in +concreto, possesses only subjective validity. One person connects +the notion conveyed in a word with one thing, another with another +thing; and the unity of consciousness in that which is empirical, +is, in relation to that which is given by experience, not +necessarily and universally valid. + + + +SS 15. The Logical Form of all Judgements consists in the Objective + Unity of Apperception of the Conceptions contained therein. + +I could never satisfy myself with the definition which logicians +give of a judgement. It is, according to them, the representation of +a relation between two conceptions. I shall not dwell here on the +faultiness of this definition, in that it suits only for categorical +and not for hypothetical or disjunctive judgements, these latter +containing a relation not of conceptions but of judgements themselves-- +a blunder from which many evil results have followed.* It is more +important for our present purpose to observe, that this definition +does not determine in what the said relation consists. + +[*Footnote: The tedious doctrine of the four syllogistic figures concerns +only categorical syllogisms; and although it is nothing more than an +artifice by surreptitiously introducing immediate conclusions +(consequentiae immediatae) among the premises of a pure syllogism, +to give ism' give rise to an appearance of more modes of drawing a +conclusion than that in the first figure, the artifice would not +have had much success, had not its authors succeeded in bringing +categorical judgements into exclusive respect, as those to which all +others must be referred--a doctrine, however, which, according to SS +5, is utterly false.] + +But if I investigate more closely the relation of given cognitions +in every judgement, and distinguish it, as belonging to the +understanding, from the relation which is produced according to laws +of the reproductive imagination (which has only subjective +validity), I find that judgement is nothing but the mode of bringing +given cognitions under the objective unit of apperception. This is +plain from our use of the term of relation is in judgements, in +order to distinguish the objective unity of given representations from +the subjective unity. For this term indicates the relation of these +representations to the original apperception, and also their necessary +unity, even although the judgement is empirical, therefore contingent, +as in the judgement: "All bodies are heavy." I do not mean by this, +that these representations do necessarily belong to each other in +empirical intuition, but that by means of the necessary unity of +appreciation they belong to each other in the synthesis of intuitions, +that is to say, they belong to each other according to principles of +the objective determination of all our representations, in so far as +cognition can arise from them, these principles being all deduced from +the main principle of the transcendental unity of apperception. In +this way alone can there arise from this relation a judgement, that +is, a relation which has objective validity, and is perfectly distinct +from that relation of the very same representations which has only +subjective validity--a relation, to wit, which is produced according +to laws of association. According to these laws, I could only say: +"When I hold in my hand or carry a body, I feel an impression of +weight"; but I could not say: "It, the body, is heavy"; for this is +tantamount to saying both these representations are conjoined in the +object, that is, without distinction as to the condition of the +subject, and do not merely stand together in my perception, however +frequently the perceptive act may be repeated. + + + +SS 16. All Sensuous Intuitions are subject to the Categories, as + Conditions under which alone the manifold Content of them + can be united in one Consciousness. + +The manifold content given in a sensuous intuition comes necessarily +under the original synthetical unity of apperception, because +thereby alone is the unity of intuition possible (SS 13). But that +act of the understanding, by which the manifold content of given +representations (whether intuitions or conceptions) is brought under +one apperception, is the logical function of judgements (SS 15). All +the manifold, therefore, in so far as it is given in one empirical +intuition, is determined in relation to one of the logical functions +of judgement, by means of which it is brought into union in one +consciousness. Now the categories are nothing else than these +functions of judgement so far as the manifold in a given intuition +is determined in relation to them (SS 9). Consequently, the manifold +in a given intuition is necessarily subject to the categories of the +understanding. + + + +SS 17. Observation. + +The manifold in an intuition, which I call mine, is represented by +means of the synthesis of the understanding, as belonging to the +necessary unity of self-consciousness, and this takes place by means +of the category.* The category indicates accordingly that the +empirical consciousness of a given manifold in an intuition is subject +to a pure self-consciousness a priori, in the same manner as an +empirical intuition is subject to a pure sensuous intuition, which +is also a priori. In the above proposition, then, lies the beginning +of a deduction of the pure conceptions of the understanding. Now, as +the categories have their origin in the understanding alone, +independently of sensibility, I must in my deduction make +abstraction of the mode in which the manifold of an empirical +intuition is given, in order to fix my attention exclusively on the +unity which is brought by the understanding into the intuition by +means of the category. In what follows (SS 22), it will be shown, from +the mode in which the empirical intuition is given in the faculty of +sensibility, that the unity which belongs to it is no other than +that which the category (according to SS 16) imposes on the manifold +in a given intuition, and thus, its a priori validity in regard to +all objects of sense being established, the purpose of our deduction +will be fully attained. + +[*Footnote: The proof of this rests on the represented unity of intuition, +by means of which an object is given, and which always includes in +itself a synthesis of the manifold to be intuited, and also the relation +of this latter to unity of apperception.] + +But there is one thing in the above demonstration of which I could +not make abstraction, namely, that the manifold to be intuited must +be given previously to the synthesis of the understanding, and +independently of it. How this takes place remains here undetermined. +For if I cogitate an understanding which was itself intuitive (as, +for example, a divine understanding which should not represent given +objects, but by whose representation the objects themselves should +be given or produced), the categories would possess no significance +in relation to such a faculty of cognition. They are merely rules for +an understanding, whose whole power consists in thought, that is, in +the act of submitting the synthesis of the manifold which is presented +to it in intuition from a very different quarter, to the unity of +apperception; a faculty, therefore, which cognizes nothing per se, +but only connects and arranges the material of cognition, the intuition, +namely, which must be presented to it by means of the object. But to +show reasons for this peculiar character of our understandings, that +it produces unity of apperception a priori only by means of +categories, and a certain kind and number thereof, is as impossible +as to explain why we are endowed with precisely so many functions of +judgement and no more, or why time and space are the only forms of +our intuition. + + + +SS 18. In Cognition, its Application to Objects of Experience is + the only legitimate use of the Category. + +To think an object and to cognize an object are by no means the same +thing. In cognition there are two elements: firstly, the conception, +whereby an object is cogitated (the category); and, secondly, the +intuition, whereby the object is given. For supposing that to the +conception a corresponding intuition could not be given, it would +still be a thought as regards its form, but without any object, and +no cognition of anything would be possible by means of it, inasmuch +as, so far as I knew, there existed and could exist nothing to which +my thought could be applied. Now all intuition possible to us is +sensuous; consequently, our thought of an object by means of a pure +conception of the understanding, can become cognition for us only in +so far as this conception is applied to objects of the senses. +Sensuous intuition is either pure intuition (space and time) or +empirical intuition--of that which is immediately represented in space +and time by means of sensation as real. Through the determination of +pure intuition we obtain a priori cognitions of objects, as in +mathematics, but only as regards their form as phenomena; whether +there can exist things which must be intuited in this form is not +thereby established. All mathematical conceptions, therefore, are +not per se cognition, except in so far as we presuppose that there +exist things which can only be represented conformably to the form +of our pure sensuous intuition. But things in space and time are given +only in so far as they are perceptions (representations accompanied +with sensation), therefore only by empirical representation. +Consequently the pure conceptions of the understanding, even when they +are applied to intuitions a priori (as in mathematics), produce +cognition only in so far as these (and therefore the conceptions of +the understanding by means of them) can be applied to empirical +intuitions. Consequently the categories do not, even by means of +pure intuition afford us any cognition of things; they can only do +so in so far as they can be applied to empirical intuition. That is +to say, the categories serve only to render empirical cognition +possible. But this is what we call experience. Consequently, in +cognition, their application to objects of experience is the only +legitimate use of the categories. + + + +SS 19. + +The foregoing proposition is of the utmost importance, for it +determines the limits of the exercise of the pure conceptions of the +understanding in regard to objects, just as transcendental aesthetic +determined the limits of the exercise of the pure form of our sensuous +intuition. Space and time, as conditions of the possibility of the +presentation of objects to us, are valid no further than for objects +of sense, consequently, only for experience. Beyond these limits +they represent to us nothing, for they belong only to sense, and +have no reality apart from it. The pure conceptions of the +understanding are free from this limitation, and extend to objects +of intuition in general, be the intuition like or unlike to ours, +provided only it be sensuous, and not intellectual. But this extension +of conceptions beyond the range of our intuition is of no advantage; +for they are then mere empty conceptions of objects, as to the +possibility or impossibility of the existence of which they furnish +us with no means of discovery. They are mere forms of thought, without +objective reality, because we have no intuition to which the +synthetical unity of apperception, which alone the categories contain, +could be applied, for the purpose of determining an object. Our +sensuous and empirical intuition can alone give them significance +and meaning. + +If, then, we suppose an object of a non-sensuous intuition to be +given we can in that case represent it by all those predicates which +are implied in the presupposition that nothing appertaining to +sensuous intuition belongs to it; for example, that it is not +extended, or in space; that its duration is not time; that in it no +change (the effect of the determinations in time) is to be met with, +and so on. But it is no proper knowledge if I merely indicate what +the intuition of the object is not, without being able to say what +is contained in it, for I have not shown the possibility of an object +to which my pure conception of understanding could be applicable, +because I have not been able to furnish any intuition corresponding +to it, but am only able to say that our intuition is not valid for +it. But the most important point is this, that to a something of this +kind not one category can be found applicable. Take, for example, the +conception of substance, that is, something that can exist as subject, +but never as mere predicate; in regard to this conception I am quite +ignorant whether there can really be anything to correspond to such +a determination of thought, if empirical intuition did not afford me +the occasion for its application. But of this more in the sequel. + + + +SS 20. Of the Application of the Categories to Objects of the + Senses in general. + +The pure conceptions of the understanding apply to objects of +intuition in general, through the understanding alone, whether the +intuition be our own or some other, provided only it be sensuous, +but are, for this very reason, mere forms of thought, by means of +which alone no determined object can be cognized. The synthesis or +conjunction of the manifold in these conceptions relates, we have +said, only to the unity of apperception, and is for this reason the +ground of the possibility of a priori cognition, in so far as this +cognition is dependent on the understanding. This synthesis is, +therefore, not merely transcendental, but also purely intellectual. +But because a certain form of sensuous intuition exists in the mind +a priori which rests on the receptivity of the representative +faculty (sensibility), the understanding, as a spontaneity, is able +to determine the internal sense by means of the diversity of given +representations, conformably to the synthetical unity of apperception, +and thus to cogitate the synthetical unity of the apperception of +the manifold of sensuous intuition a priori, as the condition to which +must necessarily be submitted all objects of human intuition. And in +this manner the categories as mere forms of thought receive +objective reality, that is, application to objects which are given +to us in intuition, but that only as phenomena, for it is only of +phenomena that we are capable of a priori intuition. + +This synthesis of the manifold of sensuous intuition, which is +possible and necessary a priori, may be called figurative (synthesis +speciosa), in contradistinction to that which is cogitated in the mere +category in regard to the manifold of an intuition in general, and +is called connection or conjunction of the understanding (synthesis +intellectualis). Both are transcendental, not merely because they +themselves precede a priori all experience, but also because they form +the basis for the possibility of other cognition a priori. + +But the figurative synthesis, when it has relation only to the +originally synthetical unity of apperception, that is to the +transcendental unity cogitated in the categories, must, to be +distinguished from the purely intellectual conjunction, be entitled +the transcendental synthesis of imagination. Imagination is the +faculty of representing an object even without its presence in +intuition. Now, as all our intuition is sensuous, imagination, by +reason of the subjective condition under which alone it can give a +corresponding intuition to the conceptions of the understanding, +belongs to sensibility. But in so far as the synthesis of the +imagination is an act of spontaneity, which is determinative, and not, +like sense, merely determinable, and which is consequently able to +determine sense a priori, according to its form, conformably to the +unity of apperception, in so far is the imagination a faculty of +determining sensibility a priori, and its synthesis of intuitions +according to the categories must be the transcendental synthesis of +the imagination. It is an operation of the understanding on +sensibility, and the first application of the understanding to objects +of possible intuition, and at the same time the basis for the exercise +of the other functions of that faculty. As figurative, it is +distinguished from the merely intellectual synthesis, which is +produced by the understanding alone, without the aid of imagination. +Now, in so far as imagination is spontaneity, I sometimes call it also +the productive imagination, and distinguish it from the +reproductive, the synthesis of which is subject entirely to +empirical laws, those of association, namely, and which, therefore, +contributes nothing to the explanation of the possibility of a +priori cognition, and for this reason belongs not to transcendental +philosophy, but to psychology. + +We have now arrived at the proper place for explaining the paradox +which must have struck every one in our exposition of the internal +sense (SS 6), namely--how this sense represents us to our own +consciousness, only as we appear to ourselves, not as we are in +ourselves, because, to wit, we intuite ourselves only as we are +inwardly affected. Now this appears to be contradictory, inasmuch as +we thus stand in a passive relation to ourselves; and therefore in +the systems of psychology, the internal sense is commonly held to be +one with the faculty of apperception, while we, on the contrary, carefully +distinguish them. + +That which determines the internal sense is the understanding, and +its original power of conjoining the manifold of intuition, that is, +of bringing this under an apperception (upon which rests the +possibility of the understanding itself). Now, as the human +understanding is not in itself a faculty of intuition, and is unable +to exercise such a power, in order to conjoin, as it were, the +manifold of its own intuition, the synthesis of understanding is, +considered per se, nothing but the unity of action, of which, as such, +it is self-conscious, even apart from sensibility, by which, moreover, +it is able to determine our internal sense in respect of the +manifold which may be presented to it according to the form of +sensuous intuition. Thus, under the name of a transcendental synthesis +of imagination, the understanding exercises an activity upon the +passive subject, whose faculty it is; and so we are right in saying +that the internal sense is affected thereby. Apperception and its +synthetical unity are by no means one and the same with the internal +sense. The former, as the source of all our synthetical conjunction, +applies, under the name of the categories, to the manifold of +intuition in general, prior to all sensuous intuition of objects. +The internal sense, on the contrary, contains merely the form of +intuition, but without any synthetical conjunction of the manifold +therein, and consequently does not contain any determined intuition, +which is possible only through consciousness of the determination of +the manifold by the transcendental act of the imagination (synthetical +influence of the understanding on the internal sense), which I have +named figurative synthesis. + +This we can indeed always perceive in ourselves. We cannot +cogitate a geometrical line without drawing it in thought, nor a +circle without describing it, nor represent the three dimensions of +space without drawing three lines from the same point perpendicular +to one another. We cannot even cogitate time, unless, in drawing a +straight line (which is to serve as the external figurative +representation of time), we fix our attention on the act of the +synthesis of the manifold, whereby we determine successively the +internal sense, and thus attend also to the succession of this +determination. Motion as an act of the subject (not as a determination +of an object),* consequently the synthesis of the manifold in space, +if we make abstraction of space and attend merely to the act by +which we determine the internal sense according to its form, is that +which produces the conception of succession. The understanding, +therefore, does by no means find in the internal sense any such +synthesis of the manifold, but produces it, in that it affects this +sense. At the same time, how "I who think" is distinct from the "I" +which intuites itself (other modes of intuition being cogitable as +at least possible), and yet one and the same with this latter as the +same subject; how, therefore, I am able to say: "I, as an intelligence +and thinking subject, cognize myself as an object thought, so far as +I am, moreover, given to myself in intuition--only, like other +phenomena, not as I am in myself, and as considered by the +understanding, but merely as I appear"--is a question that has in it +neither more nor less difficulty than the question--"How can I be an +object to myself?" or this--"How I can be an object of my own +intuition and internal perceptions?" But that such must be the fact, +if we admit that space is merely a pure form of the phenomena of +external sense, can be clearly proved by the consideration that we +cannot represent time, which is not an object of external intuition, +in any other way than under the image of a line, which we draw in +thought, a mode of representation without which we could not cognize +the unity of its dimension, and also that we are necessitated to +take our determination of periods of time, or of points of time, for +all our internal perceptions from the changes which we perceive in +outward things. It follows that we must arrange the determinations +of the internal sense, as phenomena in time, exactly in the same +manner as we arrange those of the external senses in space. And +consequently, if we grant, respecting this latter, that by means of +them we know objects only in so far as we are affected externally, +we must also confess, with regard to the internal sense, that by means +of it we intuite ourselves only as we are internally affected by +ourselves; in other words, as regards internal intuition, we cognize +our own subject only as phenomenon, and not as it is in itself.*[2] + + +[*Footnote: Motion of an object in space does not belong to a pure +science, consequently not to geometry; because, that a thing is movable +cannot be known a priori, but only from experience. But motion, +considered as the description of a space, is a pure act of the +successive synthesis of the manifold in external intuition by means +of productive imagination, and belongs not only to geometry, but even +to transcendental philosophy.] + +[*[2]Footnote: I do not see why so much difficulty should be found +in admitting that our internal sense is affected by ourselves. Every +act of attention exemplifies it. In such an act the understanding +determines the internal sense by the synthetical conjunction which +it cogitates, conformably to the internal intuition which +corresponds to the manifold in the synthesis of the understanding. +How much the mind is usually affected thereby every one will be able +to perceive in himself.] + + + +SS 21. + +On the other hand, in the transcendental synthesis of the manifold +content of representations, consequently in the synthetical unity of +apperception, I am conscious of myself, not as I appear to myself, +nor as I am in myself, but only that "I am." This representation is +a thought, not an intuition. Now, as in order to cognize ourselves, +in addition to the act of thinking, which subjects the manifold of +every possible intuition to the unity of apperception, there is +necessary a determinate mode of intuition, whereby this manifold is +given; although my own existence is certainly not mere phenomenon +(much less mere illusion), the determination of my existence* Can only +take place conformably to the form of the internal sense, according +to the particular mode in which the manifold which I conjoin is given +in internal intuition, and I have therefore no knowledge of myself +as I am, but merely as I appear to myself. The consciousness of self +is thus very far from a knowledge of self, in which I do not use the +categories, whereby I cogitate an object, by means of the +conjunction of the manifold in one apperception. In the same way as +I require, for the sake of the cognition of an object distinct from +myself, not only the thought of an object in general (in the +category), but also an intuition by which to determine that general +conception, in the same way do I require, in order to the cognition +of myself, not only the consciousness of myself or the thought that +I think myself, but in addition an intuition of the manifold in +myself, by which to determine this thought. It is true that I exist +as an intelligence which is conscious only of its faculty of +conjunction or synthesis, but subjected in relation to the manifold +which this intelligence has to conjoin to a limitative conjunction +called the internal sense. My intelligence (that is, I) can render +that conjunction or synthesis perceptible only according to the +relations of time, which are quite beyond the proper sphere of the +conceptions of the understanding and consequently cognize itself in +respect to an intuition (which cannot possibly be intellectual, nor +given by the understanding), only as it appears to itself, and not +as it would cognize itself, if its intuition were intellectual. + + +[*Footnote: The "I think" expresses the act of determining my own +existence. My existence is thus already given by the act of consciousness; +but the mode in which I must determine my existence, that is, the mode +in which I must place the manifold belonging to my existence, is not +thereby given. For this purpose intuition of self is required, and +this intuition possesses a form given a priori, namely, time, which +is sensuous, and belongs to our receptivity of the determinable. Now, +as I do not possess another intuition of self which gives the +determining in me (of the spontaneity of which I am conscious), +prior to the act of determination, in the same manner as time gives +the determinable, it is clear that I am unable to determine my own +existence as that of a spontaneous being, but I am only able to +represent to myself the spontaneity of my thought, that is, of my +determination, and my existence remains ever determinable in a +purely sensuous manner, that is to say, like the existence of a +phenomenon. But it is because of this spontaneity that I call myself +an intelligence.] + + + +SS 22. Transcendental Deduction of the universally possible employment + in experience of the Pure Conceptions of the Understanding. + +In the metaphysical deduction, the a priori origin of categories was +proved by their complete accordance with the general logical of +thought; in the transcendental deduction was exhibited the possibility +of the categories as a priori cognitions of objects of an intuition +in general (SS 16 and 17).At present we are about to explain the +possibility of cognizing, a priori, by means of the categories, all +objects which can possibly be presented to our senses, not, indeed, +according to the form of their intuition, but according to the laws +of their conjunction or synthesis, and thus, as it were, of prescribing +laws to nature and even of rendering nature possible. For if the +categories were inadequate to this task, it would not be evident to +us why everything that is presented to our senses must be subject to +those laws which have an a priori origin in the understanding itself. + +I premise that by the term synthesis of apprehension I understand +the combination of the manifold in an empirical intuition, whereby +perception, that is, empirical consciousness of the intuition (as +phenomenon), is possible. + +We have a priori forms of the external and internal sensuous +intuition in the representations of space and time, and to these +must the synthesis of apprehension of the manifold in a phenomenon +be always comformable, because the synthesis itself can only take +place according to these forms. But space and time are not merely +forms of sensuous intuition, but intuitions themselves (which +contain a manifold), and therefore contain a priori the +determination of the unity of this manifold.* (See the Transcendent +Aesthetic.) Therefore is unity of the synthesis of the manifold +without or within us, consequently also a conjunction to which all +that is to be represented as determined in space or time must +correspond, given a priori along with (not in) these intuitions, as +the condition of the synthesis of all apprehension of them. But this +synthetical unity can be no other than that of the conjunction of +the manifold of a given intuition in general, in a primitive act of +consciousness, according to the categories, but applied to our +sensuous intuition. Consequently all synthesis, whereby alone is +even perception possible, is subject to the categories. And, as +experience is cognition by means of conjoined perceptions, the +categories are conditions of the possibility of experience and are +therefore valid a priori for all objects of experience. + +[*Footnote: Space represented as an object (as geometry really requires +it to be) contains more than the mere form of the intuition; namely, +a combination of the manifold given according to the form of sensibility +into a representation that can be intuited; so that the form of the +intuition gives us merely the manifold, but the formal intuition gives +unity of representation. In the aesthetic, I regarded this unity as +belonging entirely to sensibility, for the purpose of indicating +that it antecedes all conceptions, although it presupposes a synthesis +which does not belong to sense, through which alone, however, all +our conceptions of space and time are possible. For as by means of +this unity alone (the understanding determining the sensibility) space +and time are given as intuitions, it follows that the unity of this +intuition a priori belongs to space and time, and not to the +conception of the understanding (SS 20).] + +When, then, for example, I make the empirical intuition of a house +by apprehension of the manifold contained therein into a perception, +the necessary unity of space and of my external sensuous intuition +lies at the foundation of this act, and I, as it were, draw the form +of the house conformably to this synthetical unity of the manifold +in space. But this very synthetical unity remains, even when I +abstract the form of space, and has its seat in the understanding, +and is in fact the category of the synthesis of the homogeneous in +an intuition; that is to say, the category of quantity, to which the +aforesaid synthesis of apprehension, that is, the perception, must +be completely conformable.* + +[*Footnote: In this manner it is proved, that the synthesis of +apprehension, which is empirical, must necessarily be conformable to +the synthesis of apperception, which is intellectual, and contained +a priori in the category. It is one and the same spontaneity which +at one time, under the name of imagination, at another under that of +understanding, produces conjunction in the manifold of intuition.] + +To take another example, when I perceive the freezing of water, I +apprehend two states (fluidity and solidity), which, as such, stand +toward each other mutually in a relation of time. But in the time, +which I place as an internal intuition, at the foundation of this +phenomenon, I represent to myself synthetical unity of the manifold, +without which the aforesaid relation could not be given in an +intuition as determined (in regard to the succession of time). Now +this synthetical unity, as the a priori condition under which I +conjoin the manifold of an intuition, is, if I make abstraction of +the permanent form of my internal intuition (that is to say, of time), +the category of cause, by means of which, when applied to my +sensibility, I determine everything that occurs according to relations +of time. Consequently apprehension in such an event, and the event +itself, as far as regards the possibility of its perception, stands +under the conception of the relation of cause and effect: and so in +all other cases. + +Categories are conceptions which prescribe laws a priori to +phenomena, consequently to nature as the complex of all phenomena +(natura materialiter spectata). And now the question arises-- +inasmuch as these categories are not derived from nature, and do not +regulate themselves according to her as their model (for in that +case they would be empirical)--how it is conceivable that nature +must regulate herself according to them, in other words, how the +categories can determine a priori the synthesis of the manifold of +nature, and yet not derive their origin from her. The following is +the solution of this enigma. + +It is not in the least more difficult to conceive how the laws of the +phenomena of nature must harmonize with the understanding and with its +a priori form--that is, its faculty of conjoining the manifold--than +it is to understand how the phenomena themselves must correspond with +the a priori form of our sensuous intuition. For laws do not exist in +the phenomena any more than the phenomena exist as things in +themselves. Laws do not exist except by relation to the subject in +which the phenomena inhere, in so far as it possesses understanding, +just as phenomena have no existence except by relation to the same +existing subject in so far as it has senses. To things as things in +themselves, conformability to law must necessarily belong independently +of an understanding to cognize them. But phenomena are only +representations of things which are utterly unknown in respect to what +they are in themselves. But as mere representations, they stand under +no law of conjunction except that which the conjoining faculty +prescribes. Now that which conjoins the manifold of sensuous intuition +is imagination, a mental act to which understanding contributes unity +of intellectual synthesis, and sensibility, manifoldness of +apprehension. Now as all possible perception depends on the synthesis +of apprehension, and this empirical synthesis itself on the +transcendental, consequently on the categories, it is evident that all +possible perceptions, and therefore everything that can attain to +empirical consciousness, that is, all phenomena of nature, must, as +regards their conjunction, be subject to the categories. And nature +(considered merely as nature in general) is dependent on them, as the +original ground of her necessary conformability to law (as natura +formaliter spectata). But the pure faculty (of the understanding) of +prescribing laws a priori to phenomena by means of mere categories, is +not competent to enounce other or more laws than those on which a +nature in general, as a conformability to law of phenomena of space and +time, depends. Particular laws, inasmuch as they concern empirically +determined phenomena, cannot be entirely deduced from pure laws, +although they all stand under them. Experience must be superadded in +order to know these particular laws; but in regard to experience in +general, and everything that can be cognized as an object thereof, +these a priori laws are our only rule and guide. + + + +SS 23. Result of this Deduction of the Conceptions of the + Understanding. + +We cannot think any object except by means of the categories; we +cannot cognize any thought except by means of intuitions corresponding +to these conceptions. Now all our intuitions are sensuous, and our +cognition, in so far as the object of it is given, is empirical. But +empirical cognition is experience; consequently no a priori +cognition is possible for us, except of objects of possible +experience.* + +[Footnote: Lest my readers should stumble at this assertion, and the +conclusions that may be too rashly drawn from it, I must remind them +that the categories in the act of thought are by no means limited by +the conditions of our sensuous intuition, but have an unbounded sphere +of action. It is only the cognition of the object of thought, the +determining of the object, which requires intuition. In the absence +of intuition, our thought of an object may still have true and useful +consequences in regard to the exercise of reason by the subject. But +as this exercise of reason is not always directed on the determination +of the object, in other words, on cognition thereof, but also on the +determination of the subject and its volition, I do not intend to +treat of it in this place.] + +But this cognition, which is limited to objects of experience, is +not for that reason derived entirely, from, experience, but--and +this is asserted of the pure intuitions and the pure conceptions of +the understanding--there are, unquestionably, elements of cognition, +which exist in the mind a priori. Now there are only two ways in which +a necessary harmony of experience with the conceptions of its +objects can be cogitated. Either experience makes these conceptions +possible, or the conceptions make experience possible. The former of +these statements will not bold good with respect to the categories +(nor in regard to pure sensuous intuition), for they are a priori +conceptions, and therefore independent of experience. The assertion +of an empirical origin would attribute to them a sort of generatio +aequivoca. Consequently, nothing remains but to adopt the second +alternative (which presents us with a system, as it were, of the +epigenesis of pure reason), namely, that on the part of the +understanding the categories do contain the grounds of the possibility +of all experience. But with respect to the questions how they make +experience possible, and what are the principles of the possibility +thereof with which they present us in their application to +phenomena, the following section on the transcendental exercise of +the faculty of judgement will inform the reader. + +It is quite possible that someone may propose a species of +preformation-system of pure reason--a middle way between the two--to +wit, that the categories are neither innate and first a priori +principles of cognition, nor derived from experience, but are merely +subjective aptitudes for thought implanted in us contemporaneously +with our existence, which were so ordered and disposed by our Creator, +that their exercise perfectly harmonizes with the laws of nature which +regulate experience. Now, not to mention that with such an +hypothesis it is impossible to say at what point we must stop in the +employment of predetermined aptitudes, the fact that the categories +would in this case entirely lose that character of necessity which +is essentially involved in the very conception of them, is a +conclusive objection to it. The conception of cause, for example, +which expresses the necessity of an effect under a presupposed +condition, would be false, if it rested only upon such an arbitrary +subjective necessity of uniting certain empirical representations +according to such a rule of relation. I could not then say--"The +effect is connected with its cause in the object (that is, +necessarily)," but only, "I am so constituted that I can think this +representation as so connected, and not otherwise." Now this is just +what the sceptic wants. For in this case, all our knowledge, depending +on the supposed objective validity of our judgement, is nothing but +mere illusion; nor would there be wanting people who would deny any +such subjective necessity in respect to themselves, though they must +feel it. At all events, we could not dispute with any one on that +which merely depends on the manner in which his subject is organized. + + + +Short view of the above Deduction. + +The foregoing deduction is an exposition of the pure conceptions +of the understanding (and with them of all theoretical a priori +cognition), as principles of the possibility of experience, but of +experience as the determination of all phenomena in space and time +in general--of experience, finally, from the principle of the original +synthetical unity of apperception, as the form of the understanding +in relation to time and space as original forms of sensibility. + +I consider the division by paragraphs to be necessary only up to +this point, because we had to treat of the elementary conceptions. +As we now proceed to the exposition of the employment of these, I +shall not designate the chapters in this manner any further. + + + + +BOOK II. + +Analytic of Principles. + +General logic is constructed upon a plan which coincides exactly +with the division of the higher faculties of cognition. These are, +understanding, judgement, and reason. This science, accordingly, +treats in its analytic of conceptions, judgements, and conclusions +in exact correspondence with the functions and order of those mental +powers which we include generally under the generic denomination of +understanding. + +As this merely formal logic makes abstraction of all content of +cognition, whether pure or empirical, and occupies itself with the +mere form of thought (discursive cognition), it must contain in its +analytic a canon for reason. For the form of reason has its law, +which, without taking into consideration the particular nature of +the cognition about which it is employed, can be discovered a +priori, by the simple analysis of the action of reason into its +momenta. + +Transcendental logic, limited as it is to a determinate content, +that of pure a priori cognitions, to wit, cannot imitate general logic +in this division. For it is evident that the transcendental employment +of reason is not objectively valid, and therefore does not belong to +the logic of truth (that is, to analytic), but as a logic of illusion, +occupies a particular department in the scholastic system under the +name of transcendental dialectic. + +Understanding and judgement accordingly possess in transcendental +logic a canon of objectively valid, and therefore true exercise, and +are comprehended in the analytical department of that logic. But +reason, in her endeavours to arrive by a priori means at some true +statement concerning objects and to extend cognition beyond the bounds +of possible experience, is altogether dialectic, and her illusory +assertions cannot be constructed into a canon such as an analytic +ought to contain. + +Accordingly, the analytic of principles will be merely a canon for +the faculty of judgement, for the instruction of this faculty in its +application to phenomena of the pure conceptions of the understanding, +which contain the necessary condition for the establishment of a +priori laws. On this account, although the subject of the following +chapters is the especial principles of understanding, I shall make +use of the term Doctrine of the faculty of judgement, in order to define +more particularly my present purpose. + + + +INTRODUCTION. Of the Transcendental Faculty of judgement in General. + +If understanding in general be defined as the faculty of laws or +rules, the faculty of judgement may be termed the faculty of +subsumption under these rules; that is, of distinguishing whether this +or that does or does not stand under a given rule (casus datae legis). +General logic contains no directions or precepts for the faculty of +judgement, nor can it contain any such. For as it makes abstraction +of all content of cognition, no duty is left for it, except that of +exposing analytically the mere form of cognition in conceptions, +judgements, and conclusions, and of thereby establishing formal +rules for all exercise of the understanding. Now if this logic +wished to give some general direction how we should subsume under +these rules, that is, how we should distinguish whether this or that +did or did not stand under them, this again could not be done +otherwise than by means of a rule. But this rule, precisely because +it is a rule, requires for itself direction from the faculty of +judgement. Thus, it is evident that the understanding is capable of +being instructed by rules, but that the judgement is a peculiar +talent, which does not, and cannot require tuition, but only exercise. +This faculty is therefore the specific quality of the so-called mother +wit, the want of which no scholastic discipline can compensate. + +For although education may furnish, and, as it were, engraft upon +a limited understanding rules borrowed from other minds, yet the power +of employing these rules correctly must belong to the pupil himself; +and no rule which we can prescribe to him with this purpose is, in +the absence or deficiency of this gift of nature, secure from misuse.* +A physician therefore, a judge or a statesman, may have in his head +many admirable pathological, juridical, or political rules, in a degree +that may enable him to be a profound teacher in his particular +science, and yet in the application of these rules he may very +possibly blunder--either because he is wanting in natural judgement +(though not in understanding) and, whilst he can comprehend the +general in abstracto, cannot distinguish whether a particular case +in concreto ought to rank under the former; or because his faculty +of judgement has not been sufficiently exercised by examples and +real practice. Indeed, the grand and only use of examples, is to +sharpen the judgement. For as regards the correctness and precision +of the insight of the understanding, examples are commonly injurious +rather than otherwise, because, as casus in terminis they seldom +adequately fulfil the conditions of the rule. Besides, they often +weaken the power of our understanding to apprehend rules or laws in +their universality, independently of particular circumstances of +experience; and hence, accustom us to employ them more as formulae +than as principles. Examples are thus the go-cart of the judgement, +which he who is naturally deficient in that faculty cannot afford to +dispense with. + +[*Footnote: Deficiency in judgement is properly that which is called +stupidity; and for such a failing we know no remedy. A dull or +narrow-minded person, to whom nothing is wanting but a proper degree +of understanding, may be improved by tuition, even so far as to deserve +the epithet of learned. But as such persons frequently labour under +a deficiency in the faculty of judgement, it is not uncommon to find +men extremely learned who in the application of their science betray +a lamentable degree this irremediable want.] + +But although general logic cannot give directions to the faculty +of judgement, the case is very different as regards transcendental +logic, insomuch that it appears to be the especial duty of the +latter to secure and direct, by means of determinate rules, the +faculty of judgement in the employment of the pure understanding. For, +as a doctrine, that is, as an endeavour to enlarge the sphere of the +understanding in regard to pure a priori cognitions, philosophy is +worse than useless, since from all the attempts hitherto made, +little or no ground has been gained. But, as a critique, in order to +guard against the mistakes of the faculty of judgement (lapsus +judicii) in the employment of the few pure conceptions of the +understanding which we possess, although its use is in this case +purely negative, philosophy is called upon to apply all its +acuteness and penetration. + +But transcendental philosophy has this peculiarity, that besides +indicating the rule, or rather the general condition for rules, +which is given in the pure conception of the understanding, it can, +at the same time, indicate a priori the case to which the rule must +be applied. The cause of the superiority which, in this respect, +transcendental philosophy possesses above all other sciences except +mathematics, lies in this: it treats of conceptions which must +relate a priori to their objects, whose objective validity +consequently cannot be demonstrated a posteriori, and is, at the +same time, under the obligation of presenting in general but +sufficient tests, the conditions under which objects can be given in +harmony with those conceptions; otherwise they would be mere logical +forms, without content, and not pure conceptions of the understanding. + +Our transcendental doctrine of the faculty of judgement will contain +two chapters. The first will treat of the sensuous condition under +which alone pure conceptions of the understanding can be employed-- +that is, of the schematism of the pure understanding. The second +will treat of those synthetical judgements which are derived a +priori from pure conceptions of the understanding under those +conditions, and which lie a priori at the foundation of all other +cognitions, that is to say, it will treat of the principles of the +pure understanding. + + + +TRANSCENDENTAL DOCTRINE OF THE FACULTY OF JUDGEMENT +OR, ANALYTIC OF PRINCIPLES. + +CHAPTER I. Of the Schematism at of the Pure Conceptions + of the Understanding. + +In all subsumptions of an object under a conception, the +representation of the object must be homogeneous with the +conception; in other words, the conception must contain that which +is represented in the object to be subsumed under it. For this is +the meaning of the expression: "An object is contained under a +conception." Thus the empirical conception of a plate is homogeneous +with the pure geometrical conception of a circle, inasmuch as the +roundness which is cogitated in the former is intuited in the latter. + +But pure conceptions of the understanding, when compared with +empirical intuitions, or even with sensuous intuitions in general, +are quite heterogeneous, and never can be discovered in any intuition. +How then is the subsumption of the latter under the former, and +consequently the application of the categories to phenomena, +possible?--For it is impossible to say, for example: "Causality can +be intuited through the senses and is contained in the phenomenon."--This +natural and important question forms the real cause of the necessity +of a transcendental doctrine of the faculty of judgement, with the +purpose, to wit, of showing how pure conceptions of the +understanding can be applied to phenomena. In all other sciences, +where the conceptions by which the object is thought in the general +are not so different and heterogeneous from those which represent +the object in concreto--as it is given, it is quite unnecessary to +institute any special inquiries concerning the application of the +former to the latter. + +Now it is quite clear that there must be some third thing, which +on the one side is homogeneous with the category, and with the +phenomenon on the other, and so makes the application of the former +to the latter possible. This mediating representation must be pure +(without any empirical content), and yet must on the one side be +intellectual, on the other sensuous. Such a representation is the +transcendental schema. + +The conception of the understanding contains pure synthetical +unity of the manifold in general. Time, as the formal condition of +the manifold of the internal sense, consequently of the conjunction +of all representations, contains a priori a manifold in the pure intuition. +Now a transcendental determination of time is so far homogeneous +with the category, which constitutes the unity thereof, that it is +universal and rests upon a rule a priori. On the other hand, it is +so far homogeneous with the phenomenon, inasmuch as time is +contained in every empirical representation of the manifold. Thus an +application of the category to phenomena becomes possible, by means +of the transcendental determination of time, which, as the schema of +the conceptions of the understanding, mediates the subsumption of +the latter under the former. + +After what has been proved in our deduction of the categories, no +one, it is to be hoped, can hesitate as to the proper decision of +the question, whether the employment of these pure conceptions of +the understanding ought to be merely empirical or also transcendental; +in other words, whether the categories, as conditions of a possible +experience, relate a priori solely to phenomena, or whether, as +conditions of the possibility of things in general, their +application can be extended to objects as things in themselves. For +we have there seen that conceptions are quite impossible, and utterly +without signification, unless either to them, or at least to the +elements of which they consist, an object be given; and that, +consequently, they cannot possibly apply to objects as things in +themselves without regard to the question whether and how these may +be given to us; and, further, that the only manner in which objects +can be given to us is by means of the modification of our sensibility; +and, finally, that pure a priori conceptions, in addition to the +function of the understanding in the category, must contain a priori +formal conditions of sensibility (of the internal sense, namely), +which again contain the general condition under which alone the +category can be applied to any object. This formal and pure +condition of sensibility, to which the conception of the understanding +is restricted in its employment, we shall name the schema of the +conception of the understanding, and the procedure of the +understanding with these schemata we shall call the schematism of +the pure understanding. + +The schema is, in itself, always a mere product of the +imagination. But, as the synthesis of imagination has for its aim no +single intuition, but merely unity in the determination of +sensibility, the schema is clearly distinguishable from the image. +Thus, if I place five points one after another .... this is an image +of the number five. On the other hand, if I only think a number in +general, which may be either five or a hundred, this thought is rather +the representation of a method of representing in an image a sum +(e.g., a thousand) in conformity with a conception, than the image +itself, an image which I should find some little difficulty in +reviewing, and comparing with the conception. Now this +representation of a general procedure of the imagination to present +its image to a conception, I call the schema of this conception. + +In truth, it is not images of objects, but schemata, which lie at +the foundation of our pure sensuous conceptions. No image could ever +be adequate to our conception of a triangle in general. For the +generalness of the conception it never could attain to, as this +includes under itself all triangles, whether right-angled, +acute-angled, etc., whilst the image would always be limited to a +single part of this sphere. The schema of the triangle can exist +nowhere else than in thought, and it indicates a rule of the synthesis +of the imagination in regard to pure figures in space. Still less is +an object of experience, or an image of the object, ever to the +empirical conception. On the contrary, the conception always relates +immediately to the schema of the imagination, as a rule for the +determination of our intuition, in conformity with a certain general +conception. The conception of a dog indicates a rule, according to +which my imagination can delineate the figure of a four-footed +animal in general, without being limited to any particular +individual form which experience presents to me, or indeed to any +possible image that I can represent to myself in concreto. This +schematism of our understanding in regard to phenomena and their +mere form, is an art, hidden in the depths of the human soul, whose +true modes of action we shall only with difficulty discover and +unveil. Thus much only can we say: "The image is a product of the +empirical faculty of the productive imagination--the schema of +sensuous conceptions (of figures in space, for example) is a +product, and, as it were, a monogram of the pure imagination a priori, +whereby and according to which images first become possible, which, +however, can be connected with the conception only mediately by +means of the schema which they indicate, and are in themselves never +fully adequate to it." On the other hand, the schema of a pure +conception of the understanding is something that cannot be reduced +into any image--it is nothing else than the pure synthesis expressed +by the category, conformably, to a rule of unity according to +conceptions. It is a transcendental product of the imagination, a +product which concerns the determination of the internal sense, +according to conditions of its form (time) in respect to all +representations, in so far as these representations must be +conjoined a priori in one conception, conformably to the unity of +apperception. + +Without entering upon a dry and tedious analysis of the essential +requisites of transcendental schemata of the pure conceptions of the +understanding, we shall rather proceed at once to give an +explanation of them according to the order of the categories, and in +connection therewith. + +For the external sense the pure image of all quantities +(quantorum) is space; the pure image of all objects of sense in +general, is time. But the pure schema of quantity (quantitatis) as +a conception of the understanding, is number, a representation which +comprehends the successive addition of one to one (homogeneous +quantities). Thus, number is nothing else than the unity of the +synthesis of the manifold in a homogeneous intuition, by means of my +generating time itself in my apprehension of the intuition. + +Reality, in the pure conception of the understanding, is that +which corresponds to a sensation in general; that, consequently, the +conception of which indicates a being (in time). Negation is that +the conception of which represents a not-being (in time). The +opposition of these two consists therefore in the difference of one +and the same time, as a time filled or a time empty. Now as time is +only the form of intuition, consequently of objects as phenomena, that +which in objects corresponds to sensation is the transcendental matter +of all objects as things in themselves (Sachheit, reality). Now +every sensation has a degree or quantity by which it can fill time, +that is to say, the internal sense in respect of the representation +of an object, more or less, until it vanishes into nothing (= 0 = +negatio). Thus there is a relation and connection between reality +and negation, or rather a transition from the former to the latter, +which makes every reality representable to us as a quantum; and the +schema of a reality as the quantity of something in so far as it fills +time, is exactly this continuous and uniform generation of the reality +in time, as we descend in time from the sensation which has a +certain degree, down to the vanishing thereof, or gradually ascend +from negation to the quantity thereof. + +The schema of substance is the permanence of the real in time; +that is, the representation of it as a substratum of the empirical +determination of time; a substratum which therefore remains, whilst +all else changes. (Time passes not, but in it passes the existence +of the changeable. To time, therefore, which is itself unchangeable +and permanent, corresponds that which in the phenomenon is +unchangeable in existence, that is, substance, and it is only by it +that the succession and coexistence of phenomena can be determined +in regard to time.) + +The schema of cause and of the causality of a thing is the real +which, when posited, is always followed by something else. It +consists, therefore, in the succession of the manifold, in so far as +that succession is subjected to a rule. + +The schema of community (reciprocity of action and reaction), or the +reciprocal causality of substances in respect of their accidents, is +the coexistence of the determinations of the one with those of the +other, according to a general rule. + +The schema of possibility is the accordance of the synthesis of +different representations with the conditions of time in general +(as, for example, opposites cannot exist together at the same time +in the same thing, but only after each other), and is therefore the +determination of the representation of a thing at any time. + +The schema of reality is existence in a determined time. + +The schema of necessity is the existence of an object in all time. + +It is clear, from all this, that the schema of the category of +quantity contains and represents the generation (synthesis) of time +itself, in the successive apprehension of an object; the schema of +quality the synthesis of sensation with the representation of time, +or the filling up of time; the schema of relation the relation of +perceptions to each other in all time (that is, according to a rule +of the determination of time): and finally, the schema of modality +and its categories, time itself, as the correlative of the determination +of an object--whether it does belong to time, and how. The schemata, +therefore, are nothing but a priori determinations of time according +to rules, and these, in regard to all possible objects, following +the arrangement of the categories, relate to the series in time, the +content in time, the order in time, and finally, to the complex or +totality in time. + +Hence it is apparent that the schematism of the understanding, by +means of the transcendental synthesis of the imagination, amounts to +nothing else than the unity of the manifold of intuition in the +internal sense, and thus indirectly to the unity of apperception, as +a function corresponding to the internal sense (a receptivity). Thus, +the schemata of the pure conceptions of the understanding are the true +and only conditions whereby our understanding receives an +application to objects, and consequently significance. Finally, +therefore, the categories are only capable of empirical use, +inasmuch as they serve merely to subject phenomena to the universal +rules of synthesis, by means of an a priori necessary unity (on +account of the necessary union of all consciousness in one original +apperception); and so to render them susceptible of a complete +connection in one experience. But within this whole of possible +experience lie all our cognitions, and in the universal relation to +this experience consists transcendental truth, which antecedes all +empirical truth, and renders the latter possible. + +It is, however, evident at first sight, that although the schemata +of sensibility are the sole agents in realizing the categories, they +do, nevertheless, also restrict them, that is, they limit the +categories by conditions which lie beyond the sphere of understanding-- +namely, in sensibility. Hence the schema is properly only the +phenomenon, or the sensuous conception of an object in harmony with +the category. (Numerus est quantitas phaenomenon--sensatio realitas +phaenomenon; constans et perdurabile rerum substantia phaenomenon-- +aeternitas, necessitas, phaenomena, etc.) Now, if we remove a +restrictive condition, we thereby amplify, it appears, the formerly +limited conception. In this way, the categories in their pure +signification, free from all conditions of sensibility, ought to be +valid of things as they are, and not, as the schemata represent +them, merely as they appear; and consequently the categories must have +a significance far more extended, and wholly independent of all +schemata. In truth, there does always remain to the pure conceptions +of the understanding, after abstracting every sensuous condition, a +value and significance, which is, however, merely logical. But in this +case, no object is given them, and therefore they have no meaning +sufficient to afford us a conception of an object. The notion of +substance, for example, if we leave out the sensuous determination +of permanence, would mean nothing more than a something which can be +cogitated as subject, without the possibility of becoming a +predicate to anything else. Of this representation I can make nothing, +inasmuch as it does not indicate to me what determinations the thing +possesses which must thus be valid as premier subject. Consequently, +the categories, without schemata are merely functions of the +understanding for the production of conceptions, but do not +represent any object. This significance they derive from +sensibility, which at the same time realizes the understanding and +restricts it. + + + +CHAPTER II. System of all Principles of the Pure Understanding. + +In the foregoing chapter we have merely considered the general +conditions under which alone the transcendental faculty of judgement +is justified in using the pure conceptions of the understanding for +synthetical judgements. Our duty at present is to exhibit in +systematic connection those judgements which the understanding +really produces a priori. For this purpose, our table of the +categories will certainly afford us the natural and safe guidance. +For it is precisely the categories whose application to possible +experience must constitute all pure a priori cognition of the +understanding; and the relation of which to sensibility will, on +that very account, present us with a complete and systematic catalogue +of all the transcendental principles of the use of the understanding. + +Principles a priori are so called, not merely because they contain +in themselves the grounds of other judgements, but also because they +themselves are not grounded in higher and more general cognitions. +This peculiarity, however, does not raise them altogether above the +need of a proof. For although there could be found no higher +cognition, and therefore no objective proof, and although such a +principle rather serves as the foundation for all cognition of the +object, this by no means hinders us from drawing a proof from the +subjective sources of the possibility of the cognition of an object. +Such a proof is necessary, moreover, because without it the +principle might be liable to the imputation of being a mere gratuitous +assertion. + +In the second place, we shall limit our investigations to those +principles which relate to the categories. For as to the principles +of transcendental aesthetic, according to which space and time are +the conditions of the possibility of things as phenomena, as also the +restriction of these principles, namely, that they cannot be applied +to objects as things in themselves--these, of course, do not fall +within the scope of our present inquiry. In like manner, the +principles of mathematical science form no part of this system, +because they are all drawn from intuition, and not from the pure +conception of the understanding. The possibility of these +principles, however, will necessarily be considered here, inasmuch +as they are synthetical judgements a priori, not indeed for the +purpose of proving their accuracy and apodeictic certainty, which is +unnecessary, but merely to render conceivable and deduce the +possibility of such evident a priori cognitions. + +But we shall have also to speak of the principle of analytical +judgements, in opposition to synthetical judgements, which is the +proper subject of our inquiries, because this very opposition will +free the theory of the latter from all ambiguity, and place it clearly +before our eyes in its true nature. + + + +SYSTEM OF THE PRINCIPLES OF THE PURE UNDERSTANDING. + +SECTION I. Of the Supreme Principle of all Analytical Judgements. + +Whatever may be the content of our cognition, and in whatever manner +our cognition may be related to its object, the universal, although +only negative conditions of all our judgements is that they do not +contradict themselves; otherwise these judgements are in themselves +(even without respect to the object) nothing. But although there may +exist no contradiction in our judgement, it may nevertheless connect +conceptions in such a manner that they do not correspond to the +object, or without any grounds either a priori or a posteriori for +arriving at such a judgement, and thus, without being +self-contradictory, a judgement may nevertheless be either false or +groundless. + +Now, the proposition: "No subject can have a predicate that +contradicts it," is called the principle of contradiction, and is a +universal but purely negative criterion of all truth. But it belongs +to logic alone, because it is valid of cognitions, merely as +cognitions and without respect to their content, and declares that +the contradiction entirely nullifies them. We can also, however, make +a positive use of this principle, that is, not merely to banish +falsehood and error (in so far as it rests upon contradiction), but +also for the cognition of truth. For if the judgement is analytical, +be it affirmative or negative, its truth must always be recognizable +by means of the principle of contradiction. For the contrary of that +which lies and is cogitated as conception in the cognition of the +object will be always properly negatived, but the conception itself +must always be affirmed of the object, inasmuch as the contrary +thereof would be in contradiction to the object. + +We must therefore hold the principle of contradiction to be the +universal and fully sufficient Principle of all analytical +cognition. But as a sufficient criterion of truth, it has no further +utility or authority. For the fact that no cognition can be at +variance with this principle without nullifying itself, constitutes +this principle the sine qua non, but not the determining ground of +the truth of our cognition. As our business at present is properly +with the synthetical part of our knowledge only, we shall always be +on our guard not to transgress this inviolable principle; but at the +same time not to expect from it any direct assistance in the +establishment of the truth of any synthetical proposition. + +There exists, however, a formula of this celebrated principle--a +principle merely formal and entirely without content--which contains +a synthesis that has been inadvertently and quite unnecessarily mixed +up with it. It is this: "It is impossible for a thing to be and not +to be at the same time." Not to mention the superfluousness of the +addition of the word impossible to indicate the apodeictic +certainty, which ought to be self-evident from the proposition itself, +the proposition is affected by the condition of time, and as it were +says: "A thing = A, which is something = B, cannot at the same time +be non-B." But both, B as well as non-B, may quite well exist in +succession. For example, a man who is young cannot at the same time +be old; but the same man can very well be at one time young, and at +another not young, that is, old. Now the principle of contradiction +as a merely logical proposition must not by any means limit its +application merely to relations of time, and consequently a formula +like the preceding is quite foreign to its true purpose. The +misunderstanding arises in this way. We first of all separate a +predicate of a thing from the conception of the thing, and +afterwards connect with this predicate its opposite, and hence do +not establish any contradiction with the subject, but only with its +predicate, which has been conjoined with the subject synthetically-- +a contradiction, moreover, which obtains only when the first and +second predicate are affirmed in the same time. If I say: "A man who +is ignorant is not learned," the condition "at the same time" must +be added, for he who is at one time ignorant, may at another be +learned. But if I say: "No ignorant man is a learned man," the +proposition is analytical, because the characteristic ignorance is +now a constituent part of the conception of the subject; and in this +case the negative proposition is evident immediately from the +proposition of contradiction, without the necessity of adding the +condition "the same time." This is the reason why I have altered the +formula of this principle--an alteration which shows very clearly +the nature of an analytical proposition. + + + +SECTION II. Of the Supreme Principle of all Synthetical Judgements. + +The explanation of the possibility of synthetical judgements is a task +with which general logic has nothing to do; indeed she needs not even +be acquainted with its name. But in transcendental logic it is the most +important matter to be dealt with--indeed the only one, if the question +is of the possibility of synthetical judgements a priori, the +conditions and extent of their validity. For when this question is +fully decided, it can reach its aim with perfect ease, the +determination, to wit, of the extent and limits of the pure +understanding. + +In an analytical judgement I do not go beyond the given conception, in +order to arrive at some decision respecting it. If the judgement is +affirmative, I predicate of the conception only that which was already +cogitated in it; if negative, I merely exclude from the conception its +contrary. But in synthetical judgements, I must go beyond the given +conception, in order to cogitate, in relation with it, something quite +different from that which was cogitated in it, a relation which is +consequently never one either of identity or contradiction, and by +means of which the truth or error of the judgement cannot be discerned +merely from the judgement itself. + +Granted, then, that we must go out beyond a given conception, in +order to compare it synthetically with another, a third thing is +necessary, in which alone the synthesis of two conceptions can +originate. Now what is this tertium quid that is to be the medium of +all synthetical judgements? It is only a complex in which all our +representations are contained, the internal sense to wit, and its form +a priori, time. + +The synthesis of our representations rests upon the imagination; +their synthetical unity (which is requisite to a judgement), upon +the unity of apperception. In this, therefore, is to be sought the +possibility of synthetical judgements, and as all three contain the +sources of a priori representations, the possibility of pure +synthetical judgements also; nay, they are necessary upon these +grounds, if we are to possess a knowledge of objects, which rests +solely upon the synthesis of representations. + +If a cognition is to have objective reality, that is, to relate to +an object, and possess sense and meaning in respect to it, it is +necessary that the object be given in some way or another. Without +this, our conceptions are empty, and we may indeed have thought by +means of them, but by such thinking we have not, in fact, cognized +anything, we have merely played with representation. To give an +object, if this expression be understood in the sense of "to +present" the object, not mediately but immediately in intuition, means +nothing else than to apply the representation of it to experience, +be that experience real or only possible. Space and time themselves, +pure as these conceptions are from all that is empirical, and +certain as it is that they are represented fully a priori in the mind, +would be completely without objective validity, and without sense +and significance, if their necessary use in the objects of +experience were not shown. Nay, the representation of them is a mere +schema, that always relates to the reproductive imagination, which +calls up the objects of experience, without which they have no +meaning. And so it is with all conceptions without distinction. + +The possibility of experience is, then, that which gives objective +reality to all our a priori cognitions. Now experience depends upon +the synthetical unity of phenomena, that is, upon a synthesis +according to conceptions of the object of phenomena in general, a +synthesis without which experience never could become knowledge, but +would be merely a rhapsody of perceptions, never fitting together into +any connected text, according to rules of a thoroughly united +(possible) consciousness, and therefore never subjected to the +transcendental and necessary unity of apperception. Experience has +therefore for a foundation, a priori principles of its form, that is +to say, general rules of unity in the synthesis of phenomena, the +objective reality of which rules, as necessary conditions even of +the possibility of experience can which rules, as necessary +conditions--even of the possibility of experience--can always be shown +in experience. But apart from this relation, a priori synthetical +propositions are absolutely impossible, because they have no third +term, that is, no pure object, in which the synthetical unity can +exhibit the objective reality of its conceptions. + +Although, then, respecting space, or the forms which productive +imagination describes therein, we do cognize much a priori in +synthetical judgements, and are really in no need of experience for +this purpose, such knowledge would nevertheless amount to nothing +but a busy trifling with a mere chimera, were not space to be +considered as the condition of the phenomena which constitute the +material of external experience. Hence those pure synthetical +judgements do relate, though but mediately, to possible experience, +or rather to the possibility of experience, and upon that alone is +founded the objective validity of their synthesis. + +While then, on the one hand, experience, as empirical synthesis, +is the only possible mode of cognition which gives reality to all +other synthesis; on the other hand, this latter synthesis, as +cognition a priori, possesses truth, that is, accordance with its +object, only in so far as it contains nothing more than what is +necessary to the synthetical unity of experience. + +Accordingly, the supreme principle of all synthetical judgements is: +"Every object is subject to the necessary conditions of the +synthetical unity of the manifold of intuition in a possible +experience." + +A priori synthetical judgements are possible when we apply the +formal conditions of the a priori intuition, the synthesis of the +imagination, and the necessary unity of that synthesis in a +transcendental apperception, to a possible cognition of experience, +and say: "The conditions of the possibility of experience in general +are at the same time conditions of the possibility of the objects of +experience, and have, for that reason, objective validity in an a +priori synthetical judgement." + + + +SECTION III. Systematic Representation of all Synthetical + Principles of the Pure Understanding. + +That principles exist at all is to be ascribed solely to the pure +understanding, which is not only the faculty of rules in regard to +that which happens, but is even the source of principles according +to which everything that can be presented to us as an object is +necessarily subject to rules, because without such rules we never +could attain to cognition of an object. Even the laws of nature, if +they are contemplated as principles of the empirical use of the +understanding, possess also a characteristic of necessity, and we +may therefore at least expect them to be determined upon grounds which +are valid a priori and antecedent to all experience. But all laws of +nature, without distinction, are subject to higher principles of the +understanding, inasmuch as the former are merely applications of the +latter to particular cases of experience. These higher principles +alone therefore give the conception, which contains the necessary +condition, and, as it were, the exponent of a rule; experience, on +the other hand, gives the case which comes under the rule. + +There is no danger of our mistaking merely empirical principles +for principles of the pure understanding, or conversely; for the +character of necessity, according to conceptions which distinguish +the latter, and the absence of this in every empirical proposition, +how extensively valid soever it may be, is a perfect safeguard against +confounding them. There are, however, pure principles a priori, +which nevertheless I should not ascribe to the pure understanding--for +this reason, that they are not derived from pure conceptions, but +(although by the mediation of the understanding) from pure intuitions. +But understanding is the faculty of conceptions. Such principles +mathematical science possesses, but their application to experience, +consequently their objective validity, nay the possibility of such +a priori synthetical cognitions (the deduction thereof) rests entirely +upon the pure understanding. + +On this account, I shall not reckon among my principles those of +mathematics; though I shall include those upon the possibility and +objective validity a priori, of principles of the mathematical +science, which, consequently, are to be looked upon as the principle +of these, and which proceed from conceptions to intuition, and not +from intuition to conceptions. + +In the application of the pure conceptions of the understanding to +possible experience, the employment of their synthesis is either +mathematical or dynamical, for it is directed partly on the +intuition alone, partly on the existence of a phenomenon. But the a +priori conditions of intuition are in relation to a possible +experience absolutely necessary, those of the existence of objects +of a possible empirical intuition are in themselves contingent. +Hence the principles of the mathematical use of the categories will +possess a character of absolute necessity, that is, will be +apodeictic; those, on the other hand, of the dynamical use, the +character of an a priori necessity indeed, but only under the +condition of empirical thought in an experience, therefore only +mediately and indirectly. Consequently they will not possess that +immediate evidence which is peculiar to the former, although their +application to experience does not, for that reason, lose its truth +and certitude. But of this point we shall be better able to judge at +the conclusion of this system of principles. + +The table of the categories is naturally our guide to the table of +principles, because these are nothing else than rules for the +objective employment of the former. Accordingly, all principles of +the pure understanding are: + + 1 + Axioms + of Intuition + + 2 3 + Anticipations Analogies + of Perception of Experience + 4 + Postulates of + Empirical Thought + in general + + +These appellations I have chosen advisedly, in order that we might +not lose sight of the distinctions in respect of the evidence and +the employment of these principles. It will, however, soon appear +that--a fact which concerns both the evidence of these principles, +and the a priori determination of phenomena--according to the categories +of quantity and quality (if we attend merely to the form of these), +the principles of these categories are distinguishable from those of +the two others, in as much as the former are possessed of an +intuitive, but the latter of a merely discursive, though in both +instances a complete, certitude. I shall therefore call the former +mathematical, and the latter dynamical principles.* It must be +observed, however, that by these terms I mean just as little in the +one case the principles of mathematics as those of general +(physical) dynamics in the other. I have here in view merely the +principles of the pure understanding, in their application to the +internal sense (without distinction of the representations given +therein), by means of which the sciences of mathematics and dynamics +become possible. Accordingly, I have named these principles rather +with reference to their application than their content; and I shall +now proceed to consider them in the order in which they stand in the +table. + + +[*Footnote: All combination (conjunctio) is either composition +(compositio) or connection (nexus). The former is the synthesis of a +manifold, the parts of which do not necessarily belong to each other. +For example, the two triangles into which a square is divided by a +diagonal, do not necessarily belong to each other, and of this kind is +the synthesis of the homogeneous in everything that can be +mathematically considered. This synthesis can be divided into those of +aggregation and coalition, the former of which is applied to extensive, +the latter to intensive quantities. The second sort of combination +(nexus) is the synthesis of a manifold, in so far as its parts do +belong necessarily to each other; for example, the accident to a +substance, or the effect to the cause. Consequently it is a synthesis +of that which though heterogeneous, is represented as connected a +priori. This combination--not an arbitrary one--I entitle dynamical +because it concerns the connection of the existence of the manifold. +This, again, may be divided into the physical synthesis, of the +phenomena divided among each other, and the metaphysical synthesis, or +the connection of phenomena a priori in the faculty of cognition.] + + +1. AXIOMS OF INTUITION. + + +The principle of these is: All Intuitions are Extensive Quantities. + + +PROOF. + + +All phenomena contain, as regards their form, an intuition in +space and time, which lies a priori at the foundation of all without +exception. Phenomena, therefore, cannot be apprehended, that is, +received into empirical consciousness otherwise than through the +synthesis of a manifold, through which the representations of a +determinate space or time are generated; that is to say, through the +composition of the homogeneous and the consciousness of the +synthetical unity of this manifold (homogeneous). Now the +consciousness of a homogeneous manifold in intuition, in so far as +thereby the representation of an object is rendered possible, is the +conception of a quantity (quanti). Consequently, even the perception +of an object as phenomenon is possible only through the same +synthetical unity of the manifold of the given sensuous intuition, +through which the unity of the composition of the homogeneous manifold +in the conception of a quantity is cogitated; that is to say, all +phenomena are quantities, and extensive quantities, because as +intuitions in space or time they must be represented by means of the +same synthesis through which space and time themselves are determined. + +An extensive quantity I call that wherein the representation of +the parts renders possible (and therefore necessarily antecedes) the +representation of the whole. I cannot represent to myself any line, +however small, without drawing it in thought, that is, without +generating from a point all its parts one after another, and in this +way alone producing this intuition. Precisely the same is the case +with every, even the smallest, portion of time. I cogitate therein +only the successive progress from one moment to another, and hence, +by means of the different portions of time and the addition of them, +a determinate quantity of time is produced. As the pure intuition in +all phenomena is either time or space, so is every phenomenon in its +character of intuition an extensive quantity, inasmuch as it can +only be cognized in our apprehension by successive synthesis (from +part to part). All phenomena are, accordingly, to be considered as +aggregates, that is, as a collection of previously given parts; +which is not the case with every sort of quantities, but only with +those which are represented and apprehended by us as extensive. + +On this successive synthesis of the productive imagination, in the +generation of figures, is founded the mathematics of extension, or +geometry, with its axioms, which express the conditions of sensuous +intuition a priori, under which alone the schema of a pure +conception of external intuition can exist; for example, "be tween +two points only one straight line is possible," "two straight lines +cannot enclose a space," etc. These are the axioms which properly relate +only to quantities (quanta) as such. + +But, as regards the quantity of a thing (quantitas), that is to say, +the answer to the question: "How large is this or that object?" +although, in respect to this question, we have various propositions +synthetical and immediately certain (indemonstrabilia); we have, in +the proper sense of the term, no axioms. For example, the +propositions: "If equals be added to equals, the wholes are equal"; +"If equals be taken from equals, the remainders are equal"; are +analytical, because I am immediately conscious of the identity of +the production of the one quantity with the production of the other; +whereas axioms must be a priori synthetical propositions. On the other +hand, the self-evident propositions as to the relation of numbers, +are certainly synthetical but not universal, like those of geometry, +and for this reason cannot be called axioms, but numerical formulae. +That 7 + 5 = 12 is not an analytical proposition. For neither in the +representation of seven, nor of five, nor of the composition of the +two numbers, do I cogitate the number twelve. (Whether I cogitate +the number in the addition of both, is not at present the question; +for in the case of an analytical proposition, the only point is +whether I really cogitate the predicate in the representation of the +subject.) But although the proposition is synthetical, it is +nevertheless only a singular proposition. In so far as regard is +here had merely to the synthesis of the homogeneous (the units), it +cannot take place except in one manner, although our use of these +numbers is afterwards general. If I say: "A triangle can be +constructed with three lines, any two of which taken together are +greater than the third," I exercise merely the pure function of the +productive imagination, which may draw the lines longer or shorter +and construct the angles at its pleasure. On the contrary, the number +seven is possible only in one manner, and so is likewise the number +twelve, which results from the synthesis of seven and five. Such +propositions, then, cannot be termed axioms (for in that case we +should have an infinity of these), but numerical formulae. + +This transcendental principle of the mathematics of phenomena +greatly enlarges our a priori cognition. For it is by this principle +alone that pure mathematics is rendered applicable in all its +precision to objects of experience, and without it the validity of +this application would not be so self-evident; on the contrary, +contradictions and confusions have often arisen on this very point. +Phenomena are not things in themselves. Empirical intuition is +possible only through pure intuition (of space and time); +consequently, what geometry affirms of the latter, is indisputably +valid of the former. All evasions, such as the statement that +objects of sense do not conform to the rules of construction in +space (for example, to the rule of the infinite divisibility of +lines or angles), must fall to the ground. For, if these objections +hold good, we deny to space, and with it to all mathematics, objective +validity, and no longer know wherefore, and how far, mathematics can +be applied to phenomena. The synthesis of spaces and times as the +essential form of all intuition, is that which renders possible the +apprehension of a phenomenon, and therefore every external experience, +consequently all cognition of the objects of experience; and +whatever mathematics in its pure use proves of the former, must +necessarily hold good of the latter. All objections are but the +chicaneries of an ill-instructed reason, which erroneously thinks to +liberate the objects of sense from the formal conditions of our +sensibility, and represents these, although mere phenomena, as +things in themselves, presented as such to our understanding. But in +this case, no a priori synthetical cognition of them could be +possible, consequently not through pure conceptions of space and the +science which determines these conceptions, that is to say, +geometry, would itself be impossible. + + + +2. ANTICIPATIONS OF PERCEPTION. + +The principle of these is: In all phenomena the Real, that +which is an object of sensation, has Intensive Quantity, +that is, has a Degree. + + +PROOF. + + +Perception is empirical consciousness, that is to say, a +consciousness which contains an element of sensation. Phenomena as +objects of perception are not pure, that is, merely formal intuitions, +like space and time, for they cannot be perceived in themselves. +[Footnote: They can be perceived only as phenomena, and some part of +them must always belong to the non-ego; whereas pure intuitions are +entirely the products of the mind itself, and as such are coguized +IN THEMSELVES.--Tr] They contain, then, over and above the intuition, +the materials for an object (through which is represented something +existing in space or time), that is to say, they contain the real of +sensation, as a representation merely subjective, which gives us merely +the consciousness that the subject is affected, and which we refer +to some external object. Now, a gradual transition from empirical +consciousness to pure consciousness is possible, inasmuch as the +real in this consciousness entirely vanishes, and there remains a +merely formal consciousness (a priori) of the manifold in time and +space; consequently there is possible a synthesis also of the +production of the quantity of a sensation from its commencement, +that is, from the pure intuition = 0 onwards up to a certain +quantity of the sensation. Now as sensation in itself is not an +objective representation, and in it is to be found neither the +intuition of space nor of time, it cannot possess any extensive +quantity, and yet there does belong to it a quantity (and that by +means of its apprehension, in which empirical consciousness can within +a certain time rise from nothing = 0 up to its given amount), +consequently an intensive quantity. And thus we must ascribe intensive +quantity, that is, a degree of influence on sense to all objects of +perception, in so far as this perception contains sensation. + +All cognition, by means of which I am enabled to cognize and +determine a priori what belongs to empirical cognition, may be +called an anticipation; and without doubt this is the sense in which +Epicurus employed his expression prholepsis. But as there is in +phenomena something which is never cognized a priori, which on this +account constitutes the proper difference between pure and empirical +cognition, that is to say, sensation (as the matter of perception), +it follows, that sensation is just that element in cognition which +cannot be at all anticipated. On the other hand, we might very well +term the pure determinations in space and time, as well in regard to +figure as to quantity, anticipations of phenomena, because they represent +a priori that which may always be given a posteriori in experience. +But suppose that in every sensation, as sensation in general, +without any particular sensation being thought of, there existed +something which could be cognized a priori, this would deserve to be +called anticipation in a special sense--special, because it may seem +surprising to forestall experience, in that which concerns the +matter of experience, and which we can only derive from itself. Yet +such really is the case here. + +Apprehension*, by means of sensation alone, fills only one moment, +that is, if I do not take into consideration a succession of many +sensations. As that in the phenomenon, the apprehension of which is +not a successive synthesis advancing from parts to an entire +representation, sensation has therefore no extensive quantity; the +want of sensation in a moment of time would represent it as empty, +consequently = 0. That which in the empirical intuition corresponds +to sensation is reality (realitas phaenomenon); that which corresponds +to the absence of it, negation = 0. Now every sensation is capable +of a diminution, so that it can decrease, and thus gradually disappear. +Therefore, between reality in a phenomenon and negation, there +exists a continuous concatenation of many possible intermediate +sensations, the difference of which from each other is always +smaller than that between the given sensation and zero, or complete +negation. That is to say, the real in a phenomenon has always a +quantity, which however is not discoverable in apprehension, +inasmuch as apprehension take place by means of mere sensation in +one instant, and not by the successive synthesis of many sensations, +and therefore does not progress from parts to the whole. Consequently, +it has a quantity, but not an extensive quantity. + +[*Footnote: Apprehension is the Kantian word for preception, in the +largest sense in which we employ that term. It is the genus which +includes under i, as species, perception proper and sensation proper--Tr] + +Now that quantity which is apprehended only as unity, and in which +plurality can be represented only by approximation to negation = O, +I term intensive quantity. Consequently, reality in a phenomenon has +intensive quantity, that is, a degree. If we consider this reality +as cause (be it of sensation or of another reality in the +phenomenon, for example, a change), we call the degree of reality in +its character of cause a momentum, for example, the momentum of +weight; and for this reason, that the degree only indicates that +quantity the apprehension of which is not successive, but +instantaneous. This, however, I touch upon only in passing, for with +causality I have at present nothing to do. + +Accordingly, every sensation, consequently every reality in +phenomena, however small it may be, has a degree, that is, an +intensive quantity, which may always be lessened, and between +reality and negation there exists a continuous connection of +possible realities, and possible smaller perceptions. Every colour-- +for example, red--has a degree, which, be it ever so small, is never +the smallest, and so is it always with heat, the momentum of weight, +etc. + +This property of quantities, according to which no part of them is +the smallest possible (no part simple), is called their continuity. +Space and time are quanta continua, because no part of them can be +given, without enclosing it within boundaries (points and moments), +consequently, this given part is itself a space or a time. Space, +therefore, consists only of spaces, and time of times. Points and +moments are only boundaries, that is, the mere places or positions +of their limitation. But places always presuppose intuitions which +are to limit or determine them; and we cannot conceive either space +or time composed of constituent parts which are given before space +or time. Such quantities may also be called flowing, because synthesis +(of the productive imagination) in the production of these +quantities is a progression in time, the continuity of which we are +accustomed to indicate by the expression flowing. + +All phenomena, then, are continuous quantities, in respect both to +intuition and mere perception (sensation, and with it reality). In +the former case they are extensive quantities; in the latter, intensive. +When the synthesis of the manifold of a phenomenon is interrupted, +there results merely an aggregate of several phenomena, and not +properly a phenomenon as a quantity, which is not produced by the mere +continuation of the productive synthesis of a certain kind, but by +the repetition of a synthesis always ceasing. For example, if I call +thirteen dollars a sum or quantity of money, I employ the term quite +correctly, inasmuch as I understand by thirteen dollars the value of +a mark in standard silver, which is, to be sure, a continuous +quantity, in which no part is the smallest, but every part might +constitute a piece of money, which would contain material for still +smaller pieces. If, however, by the words thirteen dollars I +understand so many coins (be their value in silver what it may), it +would be quite erroneous to use the expression a quantity of +dollars; on the contrary, I must call them aggregate, that is, a +number of coins. And as in every number we must have unity as the +foundation, so a phenomenon taken as unity is a quantity, and as +such always a continuous quantity (quantum continuum). + +Now, seeing all phenomena, whether considered as extensive or +intensive, are continuous quantities, the proposition: "All change +(transition of a thing from one state into another) is continuous," +might be proved here easily, and with mathematical evidence, were it +not that the causality of a change lies, entirely beyond the bounds +of a transcendental philosophy, and presupposes empirical principles. +For of the possibility of a cause which changes the condition of things, +that is, which determines them to the contrary to a certain given +state, the understanding gives us a priori no knowledge; not merely +because it has no insight into the possibility of it (for such insight +is absent in several a priori cognitions), but because the notion of +change concerns only certain determinations of phenomena, which +experience alone can acquaint us with, while their cause lies in the +unchangeable. But seeing that we have nothing which we could here +employ but the pure fundamental conceptions of all possible +experience, among which of course nothing empirical can be admitted, +we dare not, without injuring the unity of our system, anticipate +general physical science, which is built upon certain fundamental +experiences. + +Nevertheless, we are in no want of proofs of the great influence +which the principle above developed exercises in the anticipation of +perceptions, and even in supplying the want of them, so far as to +shield us against the false conclusions which otherwise we might +rashly draw. + +If all reality in perception has a degree, between which and +negation there is an endless sequence of ever smaller degrees, and +if, nevertheless, every sense must have a determinate degree of +receptivity for sensations; no perception, and consequently no +experience is possible, which can prove, either immediately or +mediately, an entire absence of all reality in a phenomenon; in +other words, it is impossible ever to draw from experience a proof +of the existence of empty space or of empty time. For in the first +place, an entire absence of reality in a sensuous intuition cannot +of course be an object of perception; secondly, such absence cannot +be deduced from the contemplation of any single phenomenon, and the +difference of the degrees in its reality; nor ought it ever to be +admitted in explanation of any phenomenon. For if even the complete +intuition of a determinate space or time is thoroughly real, that +is, if no part thereof is empty, yet because every reality has its +degree, which, with the extensive quantity of the phenomenon +unchanged, can diminish through endless gradations down to nothing +(the void), there must be infinitely graduated degrees, with which +space or time is filled, and the intensive quantity in different +phenomena may be smaller or greater, although the extensive quantity +of the intuition remains equal and unaltered. + +We shall give an example of this. Almost all natural philosophers, +remarking a great difference in the quantity of the matter of +different kinds in bodies with the same volume (partly on account of +the momentum of gravity or weight, partly on account of the momentum +of resistance to other bodies in motion), conclude unanimously that +this volume (extensive quantity of the phenomenon) must be void in +all bodies, although in different proportion. But who would suspect +that these for the most part mathematical and mechanical inquirers +into nature should ground this conclusion solely on a metaphysical +hypothesis--a sort of hypothesis which they profess to disparage and +avoid? Yet this they do, in assuming that the real in space (I must +not here call it impenetrability or weight, because these are +empirical conceptions) is always identical, and can only be +distinguished according to its extensive quantity, that is, +multiplicity. Now to this presupposition, for which they can have no +ground in experience, and which consequently is merely metaphysical, +I oppose a transcendental demonstration, which it is true will not +explain the difference in the filling up of spaces, but which +nevertheless completely does away with the supposed necessity of the +above-mentioned presupposition that we cannot explain the said +difference otherwise than by the hypothesis of empty spaces. This +demonstration, moreover, has the merit of setting the understanding +at liberty to conceive this distinction in a different manner, if the +explanation of the fact requires any such hypothesis. For we +perceive that although two equal spaces may be completely filled by +matters altogether different, so that in neither of them is there left +a single point wherein matter is not present, nevertheless, every +reality has its degree (of resistance or of weight), which, without +diminution of the extensive quantity, can become less and less ad +infinitum, before it passes into nothingness and disappears. Thus an +expansion which fills a space--for example, caloric, or any other +reality in the phenomenal world--can decrease in its degrees to +infinity, yet without leaving the smallest part of the space empty; +on the contrary, filling it with those lesser degrees as completely +as another phenomenon could with greater. My intention here is by no +means to maintain that this is really the case with the difference +of matters, in regard to their specific gravity; I wish only to prove, +from a principle of the pure understanding, that the nature of our +perceptions makes such a mode of explanation possible, and that it +is erroneous to regard the real in a phenomenon as equal quoad its +degree, and different only quoad its aggregation and extensive +quantity, and this, too, on the pretended authority of an a priori +principle of the understanding. + +Nevertheless, this principle of the anticipation of perception +must somewhat startle an inquirer whom initiation into +transcendental philosophy has rendered cautious. We must naturally +entertain some doubt whether or not the understanding can enounce +any such synthetical proposition as that respecting the degree of +all reality in phenomena, and consequently the possibility of the +internal difference of sensation itself--abstraction being made of +its empirical quality. Thus it is a question not unworthy of solution: +"How the understanding can pronounce synthetically and a priori +respecting phenomena, and thus anticipate these, even in that which +is peculiarly and merely empirical, that, namely, which concerns +sensation itself?" + +The quality of sensation is in all cases merely empirical, and +cannot be represented a priori (for example, colours, taste, etc.). +But the real--that which corresponds to sensation--in opposition to +negation = 0, only represents something the conception of which in +itself contains a being (ein seyn), and signifies nothing but the +synthesis in an empirical consciousness. That is to say, the empirical +consciousness in the internal sense can be raised from 0 to every +higher degree, so that the very same extensive quantity of +intuition, an illuminated surface, for example, excites as great a +sensation as an aggregate of many other surfaces less illuminated. +We can therefore make complete abstraction of the extensive quantity +of a phenomenon, and represent to ourselves in the mere sensation in +a certain momentum, a synthesis of homogeneous ascension from 0 up +to the given empirical consciousness, All sensations therefore as such +are given only a posteriori, but this property thereof, namely, that +they have a degree, can be known a priori. It is worthy of remark, +that in respect to quantities in general, we can cognize a priori only +a single quality, namely, continuity; but in respect to all quality +(the real in phenomena), we cannot cognize a priori anything more than +the intensive quantity thereof, namely, that they have a degree. All +else is left to experience. + + + +3. ANALOGIES OF EXPERIENCE. + +The principle of these is: Experience is possible only +through the representation of a necessary connection of Perceptions. + + +PROOF. + + +Experience is an empirical cognition; that is to say, a cognition +which determines an object by means of perceptions. It is therefore +a synthesis of perceptions, a synthesis which is not itself +contained in perception, but which contains the synthetical unity of +the manifold of perception in a consciousness; and this unity +constitutes the essential of our cognition of objects of the senses, +that is, of experience (not merely of intuition or sensation). Now +in experience our perceptions come together contingently, so that no +character of necessity in their connection appears, or can appear from +the perceptions themselves, because apprehension is only a placing +together of the manifold of empirical intuition, and no representation +of a necessity in the connected existence of the phenomena which +apprehension brings together, is to be discovered therein. But as +experience is a cognition of objects by means of perceptions, it +follows that the relation of the existence of the existence of the +manifold must be represented in experience not as it is put together +in time, but as it is objectively in time. And as time itself cannot +be perceived, the determination of the existence of objects in time +can only take place by means of their connection in time in general, +consequently only by means of a priori connecting conceptions. Now +as these conceptions always possess the character of necessity, +experience is possible only by means of a representation of the +necessary connection of perception. + +The three modi of time are permanence, succession, and +coexistence. Accordingly, there are three rules of all relations of +time in phenomena, according to which the existence of every +phenomenon is determined in respect of the unity of all time, and +these antecede all experience and render it possible. + +The general principle of all three analogies rests on the +necessary unity of apperception in relation to all possible +empirical consciousness (perception) at every time, consequently, as +this unity lies a priori at the foundation of all mental operations, +the principle rests on the synthetical unity of all phenomena +according to their relation in time. For the original apperception +relates to our internal sense (the complex of all representations), +and indeed relates a priori to its form, that is to say, the +relation of the manifold empirical consciousness in time. Now this +manifold must be combined in original apperception according to +relations of time--a necessity imposed by the a priori +transcendental unity of apperception, to which is subjected all that +can belong to my (i.e., my own) cognition, and therefore all that +can become an object for me. This synthetical and a priori +determined unity in relation of perceptions in time is therefore the +rule: "All empirical determinations of time must be subject to rules +of the general determination of time"; and the analogies of +experience, of which we are now about to treat, must be rules of +this nature. + +These principles have this peculiarity, that they do not concern +phenomena, and the synthesis of the empirical intuition thereof, but +merely the existence of phenomena and their relation to each other +in regard to this existence. Now the mode in which we apprehend a +thing in a phenomenon can be determined a priori in such a manner that +the rule of its synthesis can give, that is to say, can produce this +a priori intuition in every empirical example. But the existence of +phenomena cannot be known a priori, and although we could arrive by +this path at a conclusion of the fact of some existence, we could +not cognize that existence determinately, that is to say, we should +be incapable of anticipating in what respect the empirical intuition +of it would be distinguishable from that of others. + +The two principles above mentioned, which I called mathematical, +in consideration of the fact of their authorizing the application of +mathematic phenomena, relate to these phenomena only in regard to +their possibility, and instruct us how phenomena, as far as regards +their intuition or the real in their perception, can be generated +according to the rules of a mathematical synthesis. Consequently, +numerical quantities, and with them the determination of a +phenomenon as a quantity, can be employed in the one case as well as +in the other. Thus, for example, out of 200,000 illuminations by the +moon, I might compose and give a priori, that is construct, the degree +of our sensations of the sun-light.* We may therefore entitle these +two principles constitutive. + +[*Footnote: Kant's meaning is: The two principles enunciated under +the heads of "Axioms of Intuition," and "Anticipations of Perception," +authorize the application to phenomena of determinations of size and +number, that is of mathematic. For exampkle, I may compute the light +of the sun, and say that its quantity is a certain number of times +greater than that of the moon. In the same way, heat is measured by +the comparison of its different effects on water, &c., and on mercury +in a thermometer.--Tr] + +The case is very different with those principles whose province it +is to subject the existence of phenomena to rules a priori. For as +existence does not admit of being constructed, it is clear that they +must only concern the relations of existence and be merely +regulative principles. In this case, therefore, neither axioms nor +anticipations are to be thought of. Thus, if a perception is given +us, in a certain relation of time to other (although undetermined) +perceptions, we cannot then say a priori, what and how great (in +quantity) the other perception necessarily connected with the former +is, but only how it is connected, quoad its existence, in this given +modus of time. Analogies in philosophy mean something very different +from that which they represent in mathematics. In the latter they +are formulae, which enounce the equality of two relations of quantity, +and are always constitutive, so that if two terms of the proportion +are given, the third is also given, that is, can be constructed by +the aid of these formulae. But in philosophy, analogy is not the +equality of two quantitative but of two qualitative relations. In this +case, from three given terms, I can give a priori and cognize the +relation to a fourth member, but not this fourth term itself, although +I certainly possess a rule to guide me in the search for this fourth +term in experience, and a mark to assist me in discovering it. An +analogy of experience is therefore only a rule according to which +unity of experience must arise out of perceptions in respect to +objects (phenomena) not as a constitutive, but merely as a +regulative principle. The same holds good also of the postulates of +empirical thought in general, which relate to the synthesis of mere +intuition (which concerns the form of phenomena), the synthesis of +perception (which concerns the matter of phenomena), and the synthesis +of experience (which concerns the relation of these perceptions). +For they are only regulative principles, and clearly distinguishable +from the mathematical, which are constitutive, not indeed in regard +to the certainty which both possess a priori, but in the mode of evidence +thereof, consequently also in the manner of demonstration. + +But what has been observed of all synthetical propositions, and must +be particularly remarked in this place, is this, that these +analogies possess significance and validity, not as principles of +the transcendental, but only as principles of the empirical use of +the understanding, and their truth can therefore be proved only as +such, and that consequently the phenomena must not be subjoined directly +under the categories, but only under their schemata. For if the +objects to which those principles must be applied were things in +themselves, it would be quite impossible to cognize aught concerning +them synthetically a priori. But they are nothing but phenomena; a +complete knowledge of which--a knowledge to which all principles a +priori must at last relate--is the only possible experience. It +follows that these principles can have nothing else for their aim than +the conditions of the empirical cognition in the unity of synthesis +of phenomena. But this synthesis is cogitated only in the schema of +the pure conception of the understanding, of whose unity, as that of +a synthesis in general, the category contains the function +unrestricted by any sensuous condition. These principles will +therefore authorize us to connect phenomena according to an analogy, +with the logical and universal unity of conceptions, and +consequently to employ the categories in the principles themselves; +but in the application of them to experience, we shall use only +their schemata, as the key to their proper application, instead of +the categories, or rather the latter as restricting conditions, under +the title of "formulae" of the former. + + + +A. FIRST ANALOGY. + +Principle of the Permanence of Substance. + +In all changes of phenomena, substance is permanent, and the +quantum thereof in nature is neither increased nor diminished. + + +PROOF. + + +All phenomena exist in time, wherein alone as substratum, that is, +as the permanent form of the internal intuition, coexistence and +succession can be represented. Consequently time, in which all changes +of phenomena must be cogitated, remains and changes not, because it +is that in which succession and coexistence can be represented only +as determinations thereof. Now, time in itself cannot be an object +of perception. It follows that in objects of perception, that is, in +phenomena, there must be found a substratum which represents time in +general, and in which all change or coexistence can be perceived by +means of the relation of phenomena to it. But the substratum of all +reality, that is, of all that pertains to the existence of things, +is substance; all that pertains to existence can be cogitated only +as a determination of substance. Consequently, the permanent, in +relation to which alone can all relations of time in phenomena be +determined, is substance in the world of phenomena, that is, the +real in phenomena, that which, as the substratum of all change, +remains ever the same. Accordingly, as this cannot change in +existence, its quantity in nature can neither be increased nor +diminished. + +Our apprehension of the manifold in a phenomenon is always +successive, is Consequently always changing. By it alone we could, +therefore, never determine whether this manifold, as an object of +experience, is coexistent or successive, unless it had for a +foundation something fixed and permanent, of the existence of which +all succession and coexistence are nothing but so many modes (modi +of time). Only in the permanent, then, are relations of time +possible (for simultaneity and succession are the only relations in +time); that is to say, the permanent is the substratum of our +empirical representation of time itself, in which alone all +determination of time is possible. Permanence is, in fact, just +another expression for time, as the abiding correlate of all existence +of phenomena, and of all change, and of all coexistence. For change +does not affect time itself, but only the phenomena in time (just as +coexistence cannot be regarded as a modus of time itself, seeing +that in time no parts are coexistent, but all successive). If we +were to attribute succession to time itself, we should be obliged to +cogitate another time, in which this succession would be possible. +It is only by means of the permanent that existence in different parts +of the successive series of time receives a quantity, which we entitle +duration. For in mere succession, existence is perpetually vanishing +and recommencing, and therefore never has even the least quantity. +Without the permanent, then, no relation in time is possible. Now, +time in itself is not an object of perception; consequently the +permanent in phenomena must be regarded as the substratum of all +determination of time, and consequently also as the condition of the +possibility of all synthetical unity of perceptions, that is, of +experience; and all existence and all change in time can only be +regarded as a mode in the existence of that which abides unchangeably. +Therefore, in all phenomena, the permanent is the object in itself, +that is, the substance (phenomenon); but all that changes or can +change belongs only to the mode of the existence of this substance +or substances, consequently to its determinations. + +I find that in all ages not only the philosopher, but even the +common understanding, has preposited this permanence as a substratum +of all change in phenomena; indeed, I am compelled to believe that +they will always accept this as an indubitable fact. Only the +philosopher expresses himself in a more precise and definite manner, +when he says: "In all changes in the world, the substance remains, +and the accidents alone are changeable." But of this decidedly synthetical +proposition, I nowhere meet with even an attempt at proof; nay, it +very rarely has the good fortune to stand, as it deserves to do, at +the head of the pure and entirely a priori laws of nature. In truth, +the statement that substance is permanent, is tautological. For this +very permanence is the ground on which we apply the category of +substance to the phenomenon; and we should have been obliged to +prove that in all phenomena there is something permanent, of the +existence of which the changeable is nothing but a determination. +But because a proof of this nature cannot be dogmatical, that is, +cannot be drawn from conceptions, inasmuch as it concerns a +synthetical proposition a priori, and as philosophers never +reflected that such propositions are valid only in relation to +possible experience, and therefore cannot be proved except by means +of a deduction of the possibility of experience, it is no wonder that +while it has served as the foundation of all experience (for we feel +the need of it in empirical cognition), it has never been supported +by proof. + +A philosopher was asked: "What is the weight of smoke?" He answered: +"Subtract from the weight of the burnt wood the weight of the +remaining ashes, and you will have the weight of the smoke." Thus he +presumed it to be incontrovertible that even in fire the matter +(substance) does not perish, but that only the form of it undergoes +a change. In like manner was the saying: "From nothing comes nothing," +only another inference from the principle or permanence, or rather +of the ever-abiding existence of the true subject in phenomena. For +if that in the phenomenon which we call substance is to be the proper +substratum of all determination of time, it follows that all existence +in past as well as in future time, must be determinable by means of +it alone. Hence we are entitled to apply the term substance to a +phenomenon, only because we suppose its existence in all time, a +notion which the word permanence does not fully express, as it seems +rather to be referable to future time. However, the internal necessity +perpetually to be, is inseparably connected with the necessity +always to have been, and so the expression may stand as it is. +"Gigni de nihilo nihil; in nihilum nil posse reverti,"* are two +propositions which the ancients never parted, and which people +nowadays sometimes mistakenly disjoin, because they imagine that the +propositions apply to objects as things in themselves, and that the +former might be inimical to the dependence (even in respect of its +substance also) of the world upon a supreme cause. But this +apprehension is entirely needless, for the question in this case is +only of phenomena in the sphere of experience, the unity of which +never could be possible, if we admitted the possibility that new +things (in respect of their substance) should arise. For in that case, +we should lose altogether that which alone can represent the unity +of time, to wit, the identity of the substratum, as that through which +alone all change possesses complete and thorough unity. This +permanence is, however, nothing but the manner in which we represent +to ourselves the existence of things in the phenomenal world. + +[*Footnote: Persius, Satirae, iii.83-84.] + +The determinations of a substance, which are only particular modes +of its existence, are called accidents. They are always real, +because they concern the existence of substance (negations are only +determinations, which express the non-existence of something in the +substance). Now, if to this real in the substance we ascribe a +particular existence (for example, to motion as an accident of +matter), this existence is called inherence, in contradistinction to +the existence of substance, which we call subsistence. But hence arise +many misconceptions, and it would be a more accurate and just mode +of expression to designate the accident only as the mode in which +the existence of a substance is positively determined. Meanwhile, by +reason of the conditions of the logical exercise of our understanding, +it is impossible to avoid separating, as it were, that which in the +existence of a substance is subject to change, whilst the substance +remains, and regarding it in relation to that which is properly +permanent and radical. On this account, this category of substance +stands under the title of relation, rather because it is the condition +thereof than because it contains in itself any relation. + +Now, upon this notion of permanence rests the proper notion of the +conception change. Origin and extinction are not changes of that which +originates or becomes extinct. Change is but a mode of existence, +which follows on another mode of existence of the same object; hence +all that changes is permanent, and only the condition thereof changes. +Now since this mutation affects only determinations, which can have +a beginning or an end, we may say, employing an expression which seems +somewhat paradoxical: "Only the permanent (substance) is subject to +change; the mutable suffers no change, but rather alternation, that +is, when certain determinations cease, others begin." + +Change, when, cannot be perceived by us except in substances, and +origin or extinction in an absolute sense, that does not concern +merely a determination of the permanent, cannot be a possible +perception, for it is this very notion of the permanent which +renders possible the representation of a transition from one state +into another, and from non-being to being, which, consequently, can +be empirically cognized only as alternating determinations of that +which is permanent. Grant that a thing absolutely begins to be; we +must then have a point of time in which it was not. But how and by +what can we fix and determine this point of time, unless by that which +already exists? For a void time--preceding--is not an object of +perception; but if we connect this beginning with objects which +existed previously, and which continue to exist till the object in +question in question begins to be, then the latter can only be a +determination of the former as the permanent. The same holds good of +the notion of extinction, for this presupposes the empirical +representation of a time, in which a phenomenon no longer exists. + +Substances (in the world of phenomena) are the substratum of all +determinations of time. The beginning of some, and the ceasing to be +of other substances, would utterly do away with the only condition +of the empirical unity of time; and in that case phenomena would +relate to two different times, in which, side by side, existence would +pass; which is absurd. For there is only one time in which all +different times must be placed, not as coexistent, but as successive. + +Accordingly, permanence is a necessary condition under which alone +phenomena, as things or objects, are determinable in a possible +experience. But as regards the empirical criterion of this necessary +permanence, and with it of the substantiality of phenomena, we shall +find sufficient opportunity to speak in the sequel. + + + +B. SECOND ANALOGY. + +Principle of the Succession of Time According to the Law of Causality. +All changes take place according to the law of the connection of Cause +and Effect. + + +PROOF. + + +(That all phenomena in the succession of time are only changes, that +is, a successive being and non-being of the determinations of +substance, which is permanent; consequently that a being of +substance itself which follows on the non-being thereof, or a +non-being of substance which follows on the being thereof, in other +words, that the origin or extinction of substance itself, is +impossible--all this has been fully established in treating of the +foregoing principle. This principle might have been expressed as +follows: "All alteration (succession) of phenomena is merely +change"; for the changes of substance are not origin or extinction, +because the conception of change presupposes the same subject as +existing with two opposite determinations, and consequently as +permanent. After this premonition, we shall proceed to the proof.) + +I perceive that phenomena succeed one another, that is to say, a +state of things exists at one time, the opposite of which existed in +a former state. In this case, then, I really connect together two +perceptions in time. Now connection is not an operation of mere +sense and intuition, but is the product of a synthetical faculty of +imagination, which determines the internal sense in respect of a +relation of time. But imagination can connect these two states in +two ways, so that either the one or the other may antecede in time; +for time in itself cannot be an object of perception, and what in an +object precedes and what follows cannot be empirically determined in +relation to it. I am only conscious, then, that my imagination +places one state before and the other after; not that the one state +antecedes the other in the object. In other words, the objective +relation of the successive phenomena remains quite undetermined by +means of mere perception. Now in order that this relation may be +cognized as determined, the relation between the two states must be +so cogitated that it is thereby determined as necessary, which of them +must be placed before and which after, and not conversely. But the +conception which carries with it a necessity of synthetical unity, +can be none other than a pure conception of the understanding which +does not lie in mere perception; and in this case it is the conception +of "the relation of cause and effect," the former of which determines +the latter in time, as its necessary consequence, and not as something +which might possibly antecede (or which might in some cases not be +perceived to follow). It follows that it is only because we subject +the sequence of phenomena, and consequently all change, to the law +of causality, that experience itself, that is, empirical cognition +of phenomena, becomes possible; and consequently, that phenomena +themselves, as objects of experience, are possible only by virtue of +this law. + +Our apprehension of the manifold of phenomena is always +successive. The representations of parts succeed one another. +Whether they succeed one another in the object also, is a second point +for reflection, which was not contained in the former. Now we may +certainly give the name of object to everything, even to every +representation, so far as we are conscious thereof; but what this word +may mean in the case of phenomena, not merely in so far as they (as +representations) are objects, but only in so far as they indicate an +object, is a question requiring deeper consideration. In so far as +they, regarded merely as representations, are at the same time objects +of consciousness, they are not to be distinguished from +apprehension, that is, reception into the synthesis of imagination, +and we must therefore say: "The manifold of phenomena is always +produced successively in the mind." If phenomena were things in +themselves, no man would be able to conjecture from the succession +of our representations how this manifold is connected in the object; +for we have to do only with our representations. How things may be +in themselves, without regard to the representations through which +they affect us, is utterly beyond the sphere of our cognition. Now +although phenomena are not things in themselves, and are +nevertheless the only thing given to us to be cognized, it is my +duty to show what sort of connection in time belongs to the manifold +in phenomena themselves, while the representation of this manifold +in apprehension is always successive. For example, the apprehension +of the manifold in the phenomenon of a house which stands before me, +is successive. Now comes the question whether the manifold of this +house is in itself successive--which no one will be at all willing +to grant. But, so soon as I raise my conception of an object to the +transcendental signification thereof, I find that the house is not +a thing in itself, but only a phenomenon, that is, a representation, +the transcendental object of which remains utterly unknown. What then +am I to understand by the question: "How can the manifold be connected +in the phenomenon itself--not considered as a thing in itself, but +merely as a phenomenon?" Here that which lies in my successive apprehension +is regarded as representation, whilst the phenomenon which is given +me, notwithstanding that it is nothing more than a complex of these +representations, is regarded as the object thereof, with which my +conception, drawn from the representations of apprehension, must +harmonize. It is very soon seen that, as accordance of the cognition +with its object constitutes truth, the question now before us can only +relate to the formal conditions of empirical truth; and that the +phenomenon, in opposition to the representations of apprehension, +can only be distinguished therefrom as the object of them, if it is +subject to a rule which distinguishes it from every other +apprehension, and which renders necessary a mode of connection of +the manifold. That in the phenomenon which contains the condition of +this necessary rule of apprehension, is the object. + +Let us now proceed to our task. That something happens, that is to +say, that something or some state exists which before was not, +cannot be empirically perceived, unless a phenomenon precedes, which +does not contain in itself this state. For a reality which should +follow upon a void time, in other words, a beginning, which no state +of things precedes, can just as little be apprehended as the void time +itself. Every apprehension of an event is therefore a perception which +follows upon another perception. But as this is the case with all +synthesis of apprehension, as I have shown above in the example of +a house, my apprehension of an event is not yet sufficiently +distinguished from other apprehensions. But I remark also that if in +a phenomenon which contains an occurrence, I call the antecedent state +of my perception, A, and the following state, B, the perception B +can only follow A in apprehension, and the perception A cannot +follow B, but only precede it. For example, I see a ship float down +the stream of a river. My perception of its place lower down follows +upon my perception of its place higher up the course of the river, +and it is impossible that, in the apprehension of this phenomenon, +the vessel should be perceived first below and afterwards higher up +the stream. Here, therefore, the order in the sequence of perceptions +in apprehension is determined; and by this order apprehension is +regulated. In the former example, my perceptions in the apprehension +of a house might begin at the roof and end at the foundation, or +vice versa; or I might apprehend the manifold in this empirical +intuition, by going from left to right, and from right to left. +Accordingly, in the series of these perceptions, there was no +determined order, which necessitated my beginning at a certain +point, in order empirically to connect the manifold. But this rule +is always to be met with in the perception of that which happens, +and it makes the order of the successive perceptions in the +apprehension of such a phenomenon necessary. + +I must, therefore, in the present case, deduce the subjective +sequence of apprehension from the objective sequence of phenomena, +for otherwise the former is quite undetermined, and one phenomenon +is not distinguishable from another. The former alone proves nothing +as to the connection of the manifold in an object, for it is quite +arbitrary. The latter must consist in the order of the manifold in +a phenomenon, according to which order the apprehension of one thing +(that which happens) follows that of another thing (which precedes), +in conformity with a rule. In this way alone can I be authorized to +say of the phenomenon itself, and not merely of my own apprehension, +that a certain order or sequence is to be found therein. That is, in +other words, I cannot arrange my apprehension otherwise than in this +order. + +In conformity with this rule, then, it is necessary that in that +which antecedes an event there be found the condition of a rule, +according to which in this event follows always and necessarily; but +I cannot reverse this and go back from the event, and determine (by +apprehension) that which antecedes it. For no phenomenon goes back +from the succeeding point of time to the preceding point, although +it does certainly relate to a preceding point of time; from a given +time, on the other hand, there is always a necessary progression to +the determined succeeding time. Therefore, because there certainly +is something that follows, I must of necessity connect it with +something else, which antecedes, and upon which it follows, in +conformity with a rule, that is necessarily, so that the event, as +conditioned, affords certain indication of a condition, and this +condition determines the event. + +Let us suppose that nothing precedes an event, upon which this event +must follow in conformity with a rule. All sequence of perception +would then exist only in apprehension, that is to say, would be merely +subjective, and it could not thereby be objectively determined what +thing ought to precede, and what ought to follow in perception. In +such a case, we should have nothing but a play of representations, +which would possess no application to any object. That is to say, it +would not be possible through perception to distinguish one phenomenon +from another, as regards relations of time; because the succession +in the act of apprehension would always be of the same sort, and +therefore there would be nothing in the phenomenon to determine the +succession, and to render a certain sequence objectively necessary. +And, in this case, I cannot say that two states in a phenomenon follow +one upon the other, but only that one apprehension follows upon +another. But this is merely subjective, and does not determine an +object, and consequently cannot be held to be cognition of an +object--not even in the phenomenal world. + +Accordingly, when we know in experience that something happens, we +always presuppose that something precedes, whereupon it follows in +conformity with a rule. For otherwise I could not say of the object +that it follows; because the mere succession in my apprehension, if +it be not determined by a rule in relation to something preceding, +does not authorize succession in the object. Only, therefore, in +reference to a rule, according to which phenomena are determined in +their sequence, that is, as they happen, by the preceding state, can +I make my subjective synthesis (of apprehension) objective, and it +is only under this presupposition that even the experience of an event +is possible. + +No doubt it appears as if this were in thorough contradiction to all +the notions which people have hitherto entertained in regard to the +procedure of the human understanding. According to these opinions, +it is by means of the perception and comparison of similar +consequences following upon certain antecedent phenomena that the +understanding is led to the discovery of a rule, according to which +certain events always follow certain phenomena, and it is only by this +process that we attain to the conception of cause. Upon such a +basis, it is clear that this conception must be merely empirical, +and the rule which it furnishes us with--"Everything that happens must +have a cause"--would be just as contingent as experience itself. The +universality and necessity of the rule or law would be perfectly +spurious attributes of it. Indeed, it could not possess universal +validity, inasmuch as it would not in this case be a priori, but +founded on deduction. But the same is the case with this law as with +other pure a priori representations (e.g., space and time), which we +can draw in perfect clearness and completeness from experience, only +because we had already placed them therein, and by that means, and +by that alone, had rendered experience possible. Indeed, the logical +clearness of this representation of a rule, determining the series +of events, is possible only when we have made use thereof in +experience. Nevertheless, the recognition of this rule, as a condition +of the synthetical unity of phenomena in time, was the ground of +experience itself and consequently preceded it a priori. + +It is now our duty to show by an example that we never, even in +experience, attribute to an object the notion of succession or +effect (of an event--that is, the happening of something that did +not exist before), and distinguish it from the subjective succession +of apprehension, unless when a rule lies at the foundation, which +compels us to observe this order of perception in preference to any +other, and that, indeed, it is this necessity which first renders +possible the representation of a succession in the object. + +We have representations within us, of which also we can be +conscious. But, however widely extended, however accurate and +thoroughgoing this consciousness may be, these representations are +still nothing more than representations, that is, internal +determinations of the mind in this or that relation of time. Now how +happens it that to these representations we should set an object, or +that, in addition to their subjective reality, as modifications, we +should still further attribute to them a certain unknown objective +reality? It is clear that objective significancy cannot consist in +a relation to another representation (of that which we desire to term +object), for in that case the question again arises: "How does this +other representation go out of itself, and obtain objective +significancy over and above the subjective, which is proper to it, +as a determination of a state of mind?" If we try to discover what +sort of new property the relation to an object gives to our subjective +representations, and what new importance they thereby receive, we +shall find that this relation has no other effect than that of +rendering necessary the connection of our representations in a certain +manner, and of subjecting them to a rule; and that conversely, it is +only because a certain order is necessary in the relations of time +of our representations, that objective significancy is ascribed to +them. + +In the synthesis of phenomena, the manifold of our representations +is always successive. Now hereby is not represented an object, for +by means of this succession, which is common to all apprehension, no +one thing is distinguished from another. But so soon as I perceive +or assume that in this succession there is a relation to a state +antecedent, from which the representation follows in accordance with +a rule, so soon do I represent something as an event, or as a thing +that happens; in other words, I cognize an object to which I must assign +a certain determinate position in time, which cannot be altered, +because of the preceding state in the object. When, therefore, I +perceive that something happens, there is contained in this +representation, in the first place, the fact, that something +antecedes; because, it is only in relation to this that the +phenomenon obtains its proper relation of time, in other words, exists +after an antecedent time, in which it did not exist. But it can +receive its determined place in time only by the presupposition that +something existed in the foregoing state, upon which it follows +inevitably and always, that is, in conformity with a rule. From all +this it is evident that, in the first place, I cannot reverse the +order of succession, and make that which happens precede that upon +which it follows; and that, in the second place, if the antecedent +state be posited, a certain determinate event inevitably and +necessarily follows. Hence it follows that there exists a certain +order in our representations, whereby the present gives a sure +indication of some previously existing state, as a correlate, though +still undetermined, of the existing event which is given--a +correlate which itself relates to the event as its consequence, +conditions it, and connects it necessarily with itself in the series +of time. + +If then it be admitted as a necessary law of sensibility, and +consequently a formal condition of all perception, that the +preceding necessarily determines the succeeding time (inasmuch as I +cannot arrive at the succeeding except through the preceding), it must +likewise be an indispensable law of empirical representation of the +series of time that the phenomena of the past determine all +phenomena in the succeeding time, and that the latter, as events, +cannot take place, except in so far as the former determine their +existence in time, that is to say, establish it according to a rule. +For it is of course only in phenomena that we can empirically +cognize this continuity in the connection of times. + +For all experience and for the possibility of experience, +understanding is indispensable, and the first step which it takes in +this sphere is not to render the representation of objects clear, +but to render the representation of an object in general, possible. +It does this by applying the order of time to phenomena, and their +existence. In other words, it assigns to each phenomenon, as a +consequence, a place in relation to preceding phenomena, determined +a priori in time, without which it could not harmonize with time +itself, which determines a place a priori to all its parts. This +determination of place cannot be derived from the relation of +phenomena to absolute time (for it is not an object of perception); +but, on the contrary, phenomena must reciprocally determine the places +in time of one another, and render these necessary in the order of +time. In other words, whatever follows or happens, must follow in +conformity with a universal rule upon that which was contained in +the foregoing state. Hence arises a series of phenomena, which, by +means of the understanding, produces and renders necessary exactly +the same order and continuous connection in the series of our possible +perceptions, as is found a priori in the form of internal intuition +(time), in which all our perceptions must have place. + +That something happens, then, is a perception which belongs to a +possible experience, which becomes real only because I look upon the +phenomenon as determined in regard to its place in time, +consequently as an object, which can always be found by means of a +rule in the connected series of my perceptions. But this rule of the +determination of a thing according to succession in time is as +follows: "In what precedes may be found the condition, under which +an event always (that is, necessarily) follows." From all this it is +obvious that the principle of cause and effect is the principle of +possible experience, that is, of objective cognition of phenomena, +in regard to their relations in the succession of time. + +The proof of this fundamental proposition rests entirely on the +following momenta of argument. To all empirical cognition belongs +the synthesis of the manifold by the imagination, a synthesis which +is always successive, that is, in which the representations therein +always follow one another. But the order of succession in +imagination is not determined, and the series of successive +representations may be taken retrogressively as well as progressively. +But if this synthesis is a synthesis of apprehension (of the +manifold of a given phenomenon), then the order is determined in the +object, or to speak more accurately, there is therein an order of +successive synthesis which determines an object, and according to +which something necessarily precedes, and when this is posited, +something else necessarily follows. If, then, my perception is to +contain the cognition of an event, that is, of something which +really happens, it must be an empirical judgement, wherein we think +that the succession is determined; that is, it presupposes another +phenomenon, upon which this event follows necessarily, or in +conformity with a rule. If, on the contrary, when I posited the +antecedent, the event did not necessarily follow, I should be +obliged to consider it merely as a subjective play of my +imagination, and if in this I represented to myself anything as +objective, I must look upon it as a mere dream. Thus, the relation +of phenomena (as possible perceptions), according to which that +which happens is, as to its existence, necessarily determined in +time by something which antecedes, in conformity with a rule--in other +words, the relation of cause and effect--is the condition of the +objective validity of our empirical judgements in regard to the +sequence of perceptions, consequently of their empirical truth, and +therefore of experience. The principle of the relation of causality +in the succession of phenomena is therefore valid for all objects of +experience, because it is itself the ground of the possibility of +experience. + +Here, however, a difficulty arises, which must be resolved. The +principle of the connection of causality among phenomena is limited +in our formula to the succession thereof, although in practice we find +that the principle applies also when the phenomena exist together in +the same time, and that cause and effect may be simultaneous. For +example, there is heat in a room, which does not exist in the open +air. I look about for the cause, and find it to be the fire, Now the +fire as the cause is simultaneous with its effect, the heat of the +room. In this case, then, there is no succession as regards time, +between cause and effect, but they are simultaneous; and still the +law holds good. The greater part of operating causes in nature are +simultaneous with their effects, and the succession in time of the +latter is produced only because the cause cannot achieve the total +of its effect in one moment. But at the moment when the effect first +arises, it is always simultaneous with the causality of its cause, +because, if the cause had but a moment before ceased to be, the effect +could not have arisen. Here it must be specially remembered that we +must consider the order of time and not the lapse thereof. The +relation remains, even though no time has elapsed. The time between +the causality of the cause and its immediate effect may entirely +vanish, and the cause and effect be thus simultaneous, but the +relation of the one to the other remains always determinable according +to time. If, for example, I consider a leaden ball, which lies upon +a cushion and makes a hollow in it, as a cause, then it is +simultaneous with the effect. But I distinguish the two through the +relation of time of the dynamical connection of both. For if I lay +the ball upon the cushion, then the hollow follows upon the before +smooth surface; but supposing the cushion has, from some cause or +another, a hollow, there does not thereupon follow a leaden ball. + +Thus, the law of succession of time is in all instances the only +empirical criterion of effect in relation to the causality of the +antecedent cause. The glass is the cause of the rising of the water +above its horizontal surface, although the two phenomena are +contemporaneous. For, as soon as I draw some water with the glass from +a larger vessel, an effect follows thereupon, namely, the change of +the horizontal state which the water had in the large vessel into a +concave, which it assumes in the glass. + +This conception of causality leads us to the conception of action; +that of action, to the conception of force; and through it, to the +conception of substance. As I do not wish this critical essay, the +sole purpose of which is to treat of the sources of our synthetical +cognition a priori, to be crowded with analyses which merely +explain, but do not enlarge the sphere of our conceptions, I reserve +the detailed explanation of the above conceptions for a future +system of pure reason. Such an analysis, indeed, executed with great +particularity, may already be found in well-known works on this +subject. But I cannot at present refrain from making a few remarks +on the empirical criterion of a substance, in so far as it seems to +be more evident and more easily recognized through the conception of +action than through that of the permanence of a phenomenon. + +Where action (consequently activity and force) exists, substance +also must exist, and in it alone must be sought the seat of that +fruitful source of phenomena. Very well. But if we are called upon +to explain what we mean by substance, and wish to avoid the vice of +reasoning in a circle, the answer is by no means so easy. How shall +we conclude immediately from the action to the permanence of that which +acts, this being nevertheless an essential and peculiar criterion of +substance (phenomenon)? But after what has been said above, the +solution of this question becomes easy enough, although by the +common mode of procedure--merely analysing our conceptions--it would +be quite impossible. The conception of action indicates the relation +of the subject of causality to the effect. Now because all effect +consists in that which happens, therefore in the changeable, the +last subject thereof is the permanent, as the substratum of all that +changes, that is, substance. For according to the principle of +causality, actions are always the first ground of all change in +phenomena and, consequently, cannot be a property of a subject which +itself changes, because if this were the case, other actions and +another subject would be necessary to determine this change. From +all this it results that action alone, as an empirical criterion, is +a sufficient proof of the presence of substantiality, without any +necessity on my part of endeavouring to discover the permanence of +substance by a comparison. Besides, by this mode of induction we could +not attain to the completeness which the magnitude and strict +universality of the conception requires. For that the primary +subject of the causality of all arising and passing away, all origin +and extinction, cannot itself (in the sphere of phenomena) arise and +pass away, is a sound and safe conclusion, a conclusion which leads +us to the conception of empirical necessity and permanence in +existence, and consequently to the conception of a substance as +phenomenon. + +When something happens, the mere fact of the occurrence, without +regard to that which occurs, is an object requiring investigation. +The transition from the non-being of a state into the existence of +it, supposing that this state contains no quality which previously +existed in the phenomenon, is a fact of itself demanding inquiry. Such +an event, as has been shown in No. A, does not concern substance (for +substance does not thus originate), but its condition or state. It +is therefore only change, and not origin from nothing. If this +origin be regarded as the effect of a foreign cause, it is termed +creation, which cannot be admitted as an event among phenomena, +because the very possibility of it would annihilate the unity of +experience. If, however, I regard all things not as phenomena, but +as things in themselves and objects of understanding alone, they, +although substances, may be considered as dependent, in respect of +their existence, on a foreign cause. But this would require a very +different meaning in the words, a meaning which could not apply to +phenomena as objects of possible experience. + +How a thing can be changed, how it is possible that upon one state +existing in one point of time, an opposite state should follow in +another point of time--of this we have not the smallest conception +a priori. There is requisite for this the knowledge of real powers, +which can only be given empirically; for example, knowledge of +moving forces, or, in other words, of certain successive phenomena +(as movements) which indicate the presence of such forces. But the +form of every change, the condition under which alone it can take place +as the coming into existence of another state (be the content of the +change, that is, the state which is changed, what it may), and +consequently the succession of the states themselves can very well +be considered a priori, in relation to the law of causality and the +conditions of time.* + +[*Footnote: It must be remarked that I do not speak of the change of +certain relations, but of the change of the state. Thus, when a body +moves in a uniform manner, it does not change its state (of motion); +but only when all motion increases or decreases.] + +When a substance passes from one state, a, into another state, b, +the point of time in which the latter exists is different from, and +subsequent to that in which the former existed. In like manner, the +second state, as reality (in the phenomenon), differs from the +first, in which the reality of the second did not exist, as b from +zero. That is to say, if the state, b, differs from the state, a, only +in respect to quantity, the change is a coming into existence of +b - a, which in the former state did not exist, and in relation to +which that state is = O. + +Now the question arises how a thing passes from one state = a, +into another state = b. Between two moments there is always a +certain time, and between two states existing in these moments there +is always a difference having a certain quantity (for all parts of +phenomena are in their turn quantities). Consequently, every +transition from one state into another is always effected in a time +contained between two moments, of which the first determines the state +which leaves, and the second determines the state into the thing +passes. The thing leaves, and the second determines the state into +which the thing Both moments, then, are limitations of the time of +a change, consequently of the intermediate state between both, and +as such they belong to the total of the change. Now every change has +a cause, which evidences its causality in the whole time during which +the charge takes place. The cause, therefore, does not produce the +change all at once or in one moment, but in a time, so that, as the +time gradually increases from the commencing instant, a, to its +completion at b, in like manner also, the quantity of the reality +(b - a) is generated through the lesser degrees which are contained +between the first and last. All change is therefore possible only +through a continuous action of the causality, which, in so far as it +is uniform, we call a momentum. The change does not consist of these +momenta, but is generated or produced by them as their effect. + +Such is the law of the continuity of all change, the ground of which +is that neither time itself nor any phenomenon in time consists of +parts which are the smallest possible, but that, notwithstanding, +the state of a thing passes in the process of a change through all +these parts, as elements, to its second state. There is no smallest +degree of reality in a phenomenon, just as there is no smallest degree +in the quantity of time; and so the new state of reality grows up +out of the former state, through all the infinite degrees thereof, +the differences of which one from another, taken all together, are +less than the difference between o and a. + +It is not our business to inquire here into the utility of this +principle in the investigation of nature. But how such a +proposition, which appears so greatly to extend our knowledge of +nature, is possible completely a priori, is indeed a question which +deserves investigation, although the first view seems to demonstrate +the truth and reality of the principle, and the question, how it is +possible, may be considered superfluous. For there are so many +groundless pretensions to the enlargement of our knowledge by pure +reason that we must take it as a general rule to be mistrustful of +all such, and without a thoroughgoing and radical deduction, to believe +nothing of the sort even on the clearest dogmatical evidence. + +Every addition to our empirical knowledge, and every advance made in +the exercise of our perception, is nothing more than an extension of +the determination of the internal sense, that is to say, a progression +in time, be objects themselves what they may, phenomena, or pure +intuitions. This progression in time determines everything, and is +itself determined by nothing else. That is to say, the parts of the +progression exist only in time, and by means of the synthesis thereof, +and are not given antecedently to it. For this reason, every +transition in perception to anything which follows upon another in +time, is a determination of time by means of the production of this +perception. And as this determination of time is, always and in all +its parts, a quantity, the perception produced is to be considered +as a quantity which proceeds through all its degrees--no one of +which is the smallest possible--from zero up to its determined degree. +From this we perceive the possibility of cognizing a priori a law of +changes--a law, however, which concerns their form merely. We merely +anticipate our own apprehension, the formal condition of which, +inasmuch as it is itself to be found in the mind antecedently to all +given phenomena, must certainly be capable of being cognized a priori. + +Thus, as time contains the sensuous condition a priori of the +possibility of a continuous progression of that which exists to that +which follows it, the understanding, by virtue of the unity of +apperception, contains the condition a priori of the possibility of +a continuous determination of the position in time of all phenomena, +and this by means of the series of causes and effects, the former of +which necessitate the sequence of the latter, and thereby render +universally and for all time, and by consequence, objectively, valid +the empirical cognition of the relations of time. + + + +C. THIRD ANALOGY. + +Principle of Coexistence, According to the Law of Reciprocity or Community. + +All substances, in so far as they can be perceived in space +at the same time, exist in a state of complete reciprocity of action. + + +PROOF. + + +Things are coexistent, when in empirical intuition the perception of +the one can follow upon the perception of the other, and vice versa-- +which cannot occur in the succession of phenomena, as we have shown +in the explanation of the second principle. Thus I can perceive the +moon and then the earth, or conversely, first the earth and then the +moon; and for the reason that my perceptions of these objects can +reciprocally follow each other, I say, they exist contemporaneously. +Now coexistence is the existence of the manifold in the same time. +But time itself is not an object of perception; and therefore we cannot +conclude from the fact that things are placed in the same time, the +other fact, that the perception of these things can follow each +other reciprocally. The synthesis of the imagination in apprehension +would only present to us each of these perceptions as present in the +subject when the other is not present, and contrariwise; but would +not show that the objects are coexistent, that is to say, that, if +the one exists, the other also exists in the same time, and that this +is necessarily so, in order that the perceptions may be capable of +following each other reciprocally. It follows that a conception of +the understanding or category of the reciprocal sequence of the +determinations of phenomena (existing, as they do, apart from each +other, and yet contemporaneously), is requisite to justify us in +saying that the reciprocal succession of perceptions has its +foundation in the object, and to enable us to represent coexistence +as objective. But that relation of substances in which the one contains +determinations the ground of which is in the other substance, is the +relation of influence. And, when this influence is reciprocal, it is +the relation of community or reciprocity. Consequently the coexistence +of substances in space cannot be cognized in experience otherwise than +under the precondition of their reciprocal action. This is therefore +the condition of the possibility of things themselves as objects of +experience. + +Things are coexistent, in so far as they exist in one and the same +time. But how can we know that they exist in one and the same time? +Only by observing that the order in the synthesis of apprehension of +the manifold is arbitrary and a matter of indifference, that is to +say, that it can proceed from A, through B, C, D, to E, or +contrariwise from E to A. For if they were successive in time (and +in the order, let us suppose, which begins with A), it is quite +impossible for the apprehension in perception to begin with E and go +backwards to A, inasmuch as A belongs to past time and, therefore, +cannot be an object of apprehension. + +Let us assume that in a number of substances considered as phenomena +each is completely isolated, that is, that no one acts upon another. +Then I say that the coexistence of these cannot be an object of +possible perception and that the existence of one cannot, by any +mode of empirical synthesis, lead us to the existence of another. +For we imagine them in this case to be separated by a completely +void space, and thus perception, which proceeds from the one to the +other in time, would indeed determine their existence by means of a +following perception, but would be quite unable to distinguish whether +the one phenomenon follows objectively upon the first, or is +coexistent with it. + +Besides the mere fact of existence, then, there must be something by +means of which A determines the position of B in time and, conversely, +B the position of A; because only under this condition can +substances be empirically represented as existing contemporaneously. +Now that alone determines the position of another thing in time +which is the cause of it or of its determinations. Consequently +every substance (inasmuch as it can have succession predicated of it +only in respect of its determinations) must contain the causality of +certain determinations in another substance, and at the same time +the effects of the causality of the other in itself. That is to say, +substances must stand (mediately or immediately) in dynamical +community with each other, if coexistence is to be cognized in any +possible experience. But, in regard to objects of experience, that +is absolutely necessary without which the experience of these +objects would itself be impossible. Consequently it is absolutely +necessary that all substances in the world of phenomena, in so far +as they are coexistent, stand in a relation of complete community of +reciprocal action to each other. + +The word community has in our language [Footnote: German] two meanings, +and contains the two notions conveyed in the Latin communio and +commercium. We employ it in this place in the latter sense--that of a +dynamical community, without which even the community of place +(communio spatii) could not be empirically cognized. In our experiences +it is easy to observe that it is only the continuous influences in all +parts of space that can conduct our senses from one object to another; +that the light which plays between our eyes and the heavenly bodies +produces a mediating community between them and us, and thereby +evidences their coexistence with us; that we cannot empirically change our +position (perceive this change), unless the existence of matter throughout +the whole of space rendered possible the perception of the positions +we occupy; and that this perception can prove the contemporaneous +existence of these places only through their reciprocal influence, +and thereby also the coexistence of even the most remote objects--although +in this case the proof is only mediate. Without community, every +perception (of a phenomenon in space) is separated from every other +and isolated, and the chain of empirical representations, that is, +of experience, must, with the appearance of a new object, begin +entirely de novo, without the least connection with preceding +representations, and without standing towards these even in the +relation of time. My intention here is by no means to combat the +notion of empty space; for it may exist where our perceptions cannot +exist, inasmuch as they cannot reach thereto, and where, therefore, +no empirical perception of coexistence takes place. But in this case +it is not an object of possible experience. + +The following remarks may be useful in the way of explanation. In +the mind, all phenomena, as contents of a possible experience, must +exist in community (communio) of apperception or consciousness, and +in so far as it is requisite that objects be represented as coexistent +and connected, in so far must they reciprocally determine the position +in time of each other and thereby constitute a whole. If this +subjective community is to rest upon an objective basis, or to be +applied to substances as phenomena, the perception of one substance +must render possible the perception of another, and conversely. For +otherwise succession, which is always found in perceptions as +apprehensions, would be predicated of external objects, and their +representation of their coexistence be thus impossible. But this is +a reciprocal influence, that is to say, a real community +(commercium) of substances, without which therefore the empirical +relation of coexistence would be a notion beyond the reach of our +minds. By virtue of this commercium, phenomena, in so far as they +are apart from, and nevertheless in connection with each other, +constitute a compositum reale. Such composita are possible in many +different ways. The three dynamical relations then, from which all +others spring, are those of inherence, consequence, and composition. + +These, then, are the three analogies of experience. They are nothing +more than principles of the determination of the existence of +phenomena in time, according to the three modi of this +determination; to wit, the relation to time itself as a quantity +(the quantity of existence, that is, duration), the relation in time +as a series or succession, finally, the relation in time as the +complex of all existence (simultaneity). This unity of determination +in regard to time is thoroughly dynamical; that is to say, time is +not considered as that in which experience determines immediately to +every existence its position; for this is impossible, inasmuch as absolute +time is not an object of perception, by means of which phenomena can +be connected with each other. On the contrary, the rule of the +understanding, through which alone the existence of phenomena can +receive synthetical unity as regards relations of time, determines +for every phenomenon its position in time, and consequently a priori, +and with validity for all and every time. + +By nature, in the empirical sense of the word, we understand the +totality of phenomena connected, in respect of their existence, +according to necessary rules, that is, laws. There are therefore +certain laws (which are moreover a priori) which make nature possible; +and all empirical laws can exist only by means of experience, and by +virtue of those primitive laws through which experience itself becomes +possible. The purpose of the analogies is therefore to represent to +us the unity of nature in the connection of all phenomena under certain +exponents, the only business of which is to express the relation of +time (in so far as it contains all existence in itself) to the unity +of apperception, which can exist in synthesis only according to rules. +The combined expression of all is this: "All phenomena exist in one +nature, and must so exist, inasmuch as without this a priori unity, +no unity of experience, and consequently no determination of objects +in experience, is possible." + +As regards the mode of proof which we have employed in treating of +these transcendental laws of nature, and the peculiar character of +we must make one remark, which will at the same time be important as +a guide in every other attempt to demonstrate the truth of +intellectual and likewise synthetical propositions a priori. Had we +endeavoured to prove these analogies dogmatically, that is, from +conceptions; that is to say, had we employed this method in attempting +to show that everything which exists, exists only in that which is +permanent--that every thing or event presupposes the existence of +something in a preceding state, upon which it follows in conformity +with a rule--lastly, that in the manifold, which is coexistent, the +states coexist in connection with each other according to a rule, +all our labour would have been utterly in vain. For more conceptions +of things, analyse them as we may, cannot enable us to conclude from +the existence of one object to the existence of another. What other +course was left for us to pursue? This only, to demonstrate the +possibility of experience as a cognition in which at last all +objects must be capable of being presented to us, if the +representation of them is to possess any objective reality. Now in +this third, this mediating term, the essential form of which +consists in the synthetical unity of the apperception of all +phenomena, we found a priori conditions of the universal and necessary +determination as to time of all existences in the world of +phenomena, without which the empirical determination thereof as to +time would itself be impossible, and we also discovered rules of +synthetical unity a priori, by means of which we could anticipate +experience. For want of this method, and from the fancy that it was +possible to discover a dogmatical proof of the synthetical +propositions which are requisite in the empirical employment of the +understanding, has it happened that a proof of the principle of +sufficient reason has been so often attempted, and always in vain. +The other two analogies nobody has ever thought of, although they have +always been silently employed by the mind,* because the guiding thread +furnished by the categories was wanting, the guide which alone can +enable us to discover every hiatus, both in the system of +conceptions and of principles. + +[*Footnote: The unity of the universe, in which all phenomena to be +connected, is evidently a mere consequence of the admitted principle +of the community of all substances which are coexistent. For were +substances isolated, they could not as parts constitute a whole, and +were their connection (reciprocal action of the manifold) not +necessary from the very fact of coexistence, we could not conclude +from the fact of the latter as a merely ideal relation to the former +as a real one. We have, however, shown in its place that community +is the proper ground of the possibility of an empirical cognition of +coexistence, and that we may therefore properly reason from the latter +to the former as its condition.] + + + +4. THE POSTULATES OF EMPIRICAL THOUGHT. + +1. That which agrees with the formal conditions (intuition and +conception) of experience, is possible. + +2. That which coheres with the material conditions of experience +(sensation), is real. + +3. That whose coherence with the real is determined according to +universal conditions of experience is (exists) necessary. + + +Explanation. + + +The categories of modality possess this peculiarity, that they do +not in the least determine the object, or enlarge the conception to +which they are annexed as predicates, but only express its relation +to the faculty of cognition. Though my conception of a thing is in +itself complete, I am still entitled to ask whether the object of it +is merely possible, or whether it is also real, or, if the latter, +whether it is also necessary. But hereby the object itself is not more +definitely determined in thought, but the question is only in what +relation it, including all its determinations, stands to the +understanding and its employment in experience, to the empirical +faculty of judgement, and to the reason of its application to +experience. + +For this very reason, too, the categories of modality are nothing +more than explanations of the conceptions of possibility, reality, +and necessity, as employed in experience, and at the same time, +restrictions of all the categories to empirical use alone, not +authorizing the transcendental employment of them. For if they are +to have something more than a merely logical significance, and to be +something more than a mere analytical expression of the form of +thought, and to have a relation to things and their possibility, +reality, or necessity, they must concern possible experience and its +synthetical unity, in which alone objects of cognition can be given. + +The postulate of the possibility of things requires also, that the +conception of the things agree with the formal conditions of our +experience in general. But this, that is to say, the objective form +of experience, contains all the kinds of synthesis which are requisite +for the cognition of objects. A conception which contains a +synthesis must be regarded as empty and, without reference to an +object, if its synthesis does not belong to experience--either as +borrowed from it, and in this case it is called an empirical +conception, or such as is the ground and a priori condition of +experience (its form), and in this case it is a pure conception, a +conception which nevertheless belongs to experience, inasmuch as its +object can be found in this alone. For where shall we find the +criterion or character of the possibility of an object which is +cogitated by means of an a priori synthetical conception, if not in +the synthesis which constitutes the form of empirical cognition of +objects? That in such a conception no contradiction exists is indeed +a necessary logical condition, but very far from being sufficient to +establish the objective reality of the conception, that is, the +possibility of such an object as is thought in the conception. Thus, +in the conception of a figure which is contained within two straight +lines, there is no contradiction, for the conceptions of two +straight lines and of their junction contain no negation of a +figure. The impossibility in such a case does not rest upon the +conception in itself, but upon the construction of it in space, that +is to say, upon the conditions of space and its determinations. But +these have themselves objective reality, that is, they apply to +possible things, because they contain a priori the form of +experience in general. + +And now we shall proceed to point out the extensive utility and +influence of this postulate of possibility. When I represent to myself +a thing that is permanent, so that everything in it which changes +belongs merely to its state or condition, from such a conception alone +I never can cognize that such a thing is possible. Or, if I +represent to myself something which is so constituted that, when it +is posited, something else follows always and infallibly, my thought +contains no self-contradiction; but whether such a property as +causality is to be found in any possible thing, my thought alone +affords no means of judging. Finally, I can represent to myself +different things (substances) which are so constituted that the +state or condition of one causes a change in the state of the other, +and reciprocally; but whether such a relation is a property of +things cannot be perceived from these conceptions, which contain a +merely arbitrary synthesis. Only from the fact, therefore, that +these conceptions express a priori the relations of perceptions in +every experience, do we know that they possess objective reality, that +is, transcendental truth; and that independent of experience, though +not independent of all relation to form of an experience in general +and its synthetical unity, in which alone objects can be empirically +cognized. + +But when we fashion to ourselves new conceptions of substances, +forces, action, and reaction, from the material presented to us by +perception, without following the example of experience in their +connection, we create mere chimeras, of the possibility of which we +cannot discover any criterion, because we have not taken experience +for our instructress, though we have borrowed the conceptions from +her. Such fictitious conceptions derive their character of possibility +not, like the categories, a priori, as conceptions on which all +experience depends, but only, a posteriori, as conceptions given by +means of experience itself, and their possibility must either be +cognized a posteriori and empirically, or it cannot be cognized at +all. A substance which is permanently present in space, yet without +filling it (like that tertium quid between matter and the thinking +subject which some have tried to introduce into metaphysics), or a +peculiar fundamental power of the mind of intuiting the future by +anticipation (instead of merely inferring from past and present +events), or, finally, a power of the mind to place itself in community +of thought with other men, however distant they may be--these are +conceptions the possibility of which has no ground to rest upon. For +they are not based upon experience and its known laws; and, without +experience, they are a merely arbitrary conjunction of thoughts, +which, though containing no internal contradiction, has no claim to +objective reality, neither, consequently, to the possibility of such +an object as is thought in these conceptions. As far as concerns +reality, it is self-evident that we cannot cogitate such a possibility +in concreto without the aid of experience; because reality is +concerned only with sensation, as the matter of experience, and not +with the form of thought, with which we can no doubt indulge in +shaping fancies. + +But I pass by everything which derives its possibility from +reality in experience, and I purpose treating here merely of the +possibility of things by means of a priori conceptions. I maintain, +then, that the possibility of things is not derived from such +conceptions per se, but only when considered as formal and objective +conditions of an experience in general. + +It seems, indeed, as if the possibility of a triangle could be +cognized from the conception of it alone (which is certainly +independent of experience); for we can certainly give to the +conception a corresponding object completely a priori, that is to say, +we can construct it. But as a triangle is only the form of an +object, it must remain a mere product of the imagination, and the +possibility of the existence of an object corresponding to it must +remain doubtful, unless we can discover some other ground, unless we +know that the figure can be cogitated under the conditions upon +which all objects of experience rest. Now, the facts that space is +a formal condition a priori of external experience, that the formative +synthesis, by which we construct a triangle in imagination, is the +very same as that we employ in the apprehension of a phenomenon for +the purpose of making an empirical conception of it, are what alone +connect the notion of the possibility of such a thing, with the +conception of it. In the same manner, the possibility of continuous +quantities, indeed of quantities in general, for the conceptions of +them are without exception synthetical, is never evident from the +conceptions in themselves, but only when they are considered as the +formal conditions of the determination of objects in experience. And +where, indeed, should we look for objects to correspond to our +conceptions, if not in experience, by which alone objects are +presented to us? It is, however, true that without antecedent +experience we can cognize and characterize the possibility of +things, relatively to the formal conditions, under which something +is determined in experience as an object, consequently, completely +a priori. But still this is possible only in relation to experience +and within its limits. + +The postulate concerning the cognition of the reality of things +requires perception, consequently conscious sensation, not indeed +immediately, that is, of the object itself, whose existence is to be +cognized, but still that the object have some connection with a real +perception, in accordance with the analogies of experience, which +exhibit all kinds of real connection in experience. + +From the mere conception of a thing it is impossible to conclude its +existence. For, let the conception be ever so complete, and containing +a statement of all the determinations of the thing, the existence of +it has nothing to do with all this, but only with thew question +whether such a thing is given, so that the perception of it can in +every case precede the conception. For the fact that the conception +of it precedes the perception, merely indicates the possibility of +its existence; it is perception which presents matter to the conception, +that is the sole criterion of reality. Prior to the perception of +the thing, however, and therefore comparatively a priori, we are +able to cognize its existence, provided it stands in connection with +some perceptions according to the principles of the empirical +conjunction of these, that is, in conformity with the analogies of +perception. For, in this case, the existence of the supposed thing +is connected with our perception in a possible experience, and we +are able, with the guidance of these analogies, to reason in the +series of possible perceptions from a thing which we do really +perceive to the thing we do not perceive. Thus, we cognize the +existence of a magnetic matter penetrating all bodies from the +perception of the attraction of the steel-filings by the magnet, +although the constitution of our organs renders an immediate +perception of this matter impossible for us. For, according to the +laws of sensibility and the connected context of our perceptions, we +should in an experience come also on an immediate empirical +intuition of this matter, if our senses were more acute--but this +obtuseness has no influence upon and cannot alter the form of possible +experience in general. Our knowledge of the existence of things +reaches as far as our perceptions, and what may be inferred from +them according to empirical laws, extend. If we do not set out from +experience, or do not proceed according to the laws of the empirical +connection of phenomena, our pretensions to discover the existence +of a thing which we do not immediately perceive are vain. Idealism, +however, brings forward powerful objections to these rules for proving +existence mediately. This is, therefore, the proper place for its +refutation. + + + +REFUTATION OF IDEALISM. + +Idealism--I mean material idealism--is the theory which declares the +existence of objects in space without us to be either () doubtful +and indemonstrable, or (2) false and impossible. The first is the +problematical idealism of Descartes, who admits the undoubted +certainty of only one empirical assertion (assertio), to wit, "I +am." The second is the dogmatical idealism of Berkeley, who +maintains that space, together with all the objects of which it is +the inseparable condition, is a thing which is in itself impossible, +and that consequently the objects in space are mere products of the +imagination. The dogmatical theory of idealism is unavoidable, if we +regard space as a property of things in themselves; for in that case +it is, with all to which it serves as condition, a nonentity. But +the foundation for this kind of idealism we have already destroyed +in the transcendental aesthetic. Problematical idealism, which makes +no such assertion, but only alleges our incapacity to prove the +existence of anything besides ourselves by means of immediate +experience, is a theory rational and evidencing a thorough and +philosophical mode of thinking, for it observes the rule not to form +a decisive judgement before sufficient proof be shown. The desired +proof must therefore demonstrate that we have experience of external +things, and not mere fancies. For this purpose, we must prove, that +our internal and, to Descartes, indubitable experience is itself +possible only under the previous assumption of external experience. + + + +THEOREM. + +The simple but empirically determined consciousness of +my own existence proves the existence of external objects in space. + + +PROOF + + +I am conscious of my own existence as determined in time. All +determination in regard to time presupposes the existence of something +permanent in perception. But this permanent something cannot be +something in me, for the very reason that my existence in time is +itself determined by this permanent something. It follows that the +perception of this permanent existence is possible only through a +thing without me and not through the mere representation of a thing +without me. Consequently, the determination of my existence in time +is possible only through the existence of real things external to me. +Now, consciousness in time is necessarily connected with the +consciousness of the possibility of this determination in time. +Hence it follows that consciousness in time is necessarily connected +also with the existence of things without me, inasmuch as the +existence of these things is the condition of determination in time. +That is to say, the consciousness of my own existence is at the same +time an immediate consciousness of the existence of other things +without me. + +Remark I. The reader will observe, that in the foregoing proof the +game which idealism plays is retorted upon itself, and with more +justice. It assumed that the only immediate experience is internal +and that from this we can only infer the existence of external things. +But, as always happens, when we reason from given effects to +determined causes, idealism has reasoned with too much haste and +uncertainty, for it is quite possible that the cause of our +representations may lie in ourselves, and that we ascribe it falsely +to external things. But our proof shows that external experience is +properly immediate,* that only by virtue of it--not, indeed, the +consciousness of our own existence, but certainly the determination +of our existence in time, that is, internal experience--is possible. +It is true, that the representation "I am," which is the expression +of the consciousness which can accompany all my thoughts, is that which +immediately includes the existence of a subject. But in this +representation we cannot find any knowledge of the subject, and +therefore also no empirical knowledge, that is, experience. For +experience contains, in addition to the thought of something existing, +intuition, and in this case it must be internal intuition, that is, +time, in relation to which the subject must be determined. But the +existence of external things is absolutely requisite for this purpose, +so that it follows that internal experience is itself possible only +mediately and through external experience. + +[*Footnote: The immediate consciousness of the existence of external +things is, in the preceding theorem, not presupposed, but proved, by +the possibility of this consciousness understood by us or not. The +question as to the possibility of it would stand thus: "Have we an +internal sense, but no external sense, and is our belief in external +perception a mere delusion?" But it is evident that, in order merely +to fancy to ourselves anything as external, that is, to present it +to the sense in intuition we must already possess an external sense, +and must thereby distinguish immediately the mere receptivity of an +external intuition from the spontaneity which characterizes every +act of imagination. For merely to imagine also an external sense, +would annihilate the faculty of intuition itself which is to be +determined by the imagination.] + +Remark II. Now with this view all empirical use of our faculty of +cognition in the determination of time is in perfect accordance. Its +truth is supported by the fact that it is possible to perceive a +determination of time only by means of a change in external +relations (motion) to the permanent in space (for example, we become +aware of the sun's motion by observing the changes of his relation +to the objects of this earth). But this is not all. We find that we +possess nothing permanent that can correspond and be submitted to +the conception of a substance as intuition, except matter. This idea +of permanence is not itself derived from external experience, but is +an a priori necessary condition of all determination of time, +consequently also of the internal sense in reference to our own +existence, and that through the existence of external things. In the +representation "I," the consciousness of myself is not an intuition, +but a merely intellectual representation produced by the spontaneous +activity of a thinking subject. It follows, that this "I" has not +any predicate of intuition, which, in its character of permanence, +could serve as correlate to the determination of time in the +internal sense--in the same way as impenetrability is the correlate +of matter as an empirical intuition. + +Remark III. From the fact that the existence of external things is +a necessary condition of the possibility of a determined consciousness +of ourselves, it does not follow that every intuitive representation +of external things involves the existence of these things, for their +representations may very well be the mere products of the +imagination (in dreams as well as in madness); though, indeed, these +are themselves created by the reproduction of previous external +perceptions, which, as has been shown, are possible only through the +reality of external objects. The sole aim of our remarks has, however, +been to prove that internal experience in general is possible only +through external experience in general. Whether this or that +supposed experience be purely imaginary must be discovered from its +particular determinations and by comparing these with the criteria +of all real experience. + +Finally, as regards the third postulate, it applies to material +necessity in existence, and not to merely formal and logical necessity +in the connection of conceptions. Now as we cannot cognize completely a +priori the existence of any object of sense, though we can do so +comparatively a priori, that is, relatively to some other previously +given existence--a cognition, however, which can only be of such an +existence as must be contained in the complex of experience, of which +the previously given perception is a part--the necessity of existence +can never be cognized from conceptions, but always, on the contrary, +from its connection with that which is an object of perception. But the +only existence cognized, under the condition of other given phenomena, +as necessary, is the existence of effects from given causes in +conformity with the laws of causality. It is consequently not the +necessity of the existence of things (as substances), but the necessity +of the state of things that we cognize, and that not immediately, but +by means of the existence of other states given in perception, +according to empirical laws of causality. Hence it follows that the +criterion of necessity is to be found only in the law of possible +experience--that everything which happens is determined a priori in the +phenomenon by its cause. Thus we cognize only the necessity of effects +in nature, the causes of which are given us. Moreover, the criterion of +necessity in existence possesses no application beyond the field of +possible experience, and even in this it is not valid of the existence +of things as substances, because these can never be considered as +empirical effects, or as something that happens and has a beginning. +Necessity, therefore, regards only the relations of phenomena according +to the dynamical law of causality, and the possibility grounded +thereon, of reasoning from some given existence (of a cause) a priori +to another existence (of an effect). "Everything that happens is +hypothetically necessary," is a principle which subjects the changes +that take place in the world to a law, that is, to a rule of necessary +existence, without which nature herself could not possibly exist. Hence +the proposition, "Nothing happens by blind chance (in mundo non datur +casus)," is an a priori law of nature. The case is the same with the +proposition, "Necessity in nature is not blind," that is, it is +conditioned, consequently intelligible necessity (non datur fatum). +Both laws subject the play of change to "a nature of things (as +phenomena)," or, which is the same thing, to the unity of the +understanding, and through the understanding alone can changes belong +to an experience, as the synthetical unity of phenomena. Both belong to +the class of dynamical principles. The former is properly a consequence +of the principle of causality--one of the analogies of experience. The +latter belongs to the principles of modality, which to the +determination of causality adds the conception of necessity, which is +itself, however, subject to a rule of the understanding. The principle +of continuity forbids any leap in the series of phenomena regarded as +changes (in mundo non datur saltus); and likewise, in the complex of +all empirical intuitions in space, any break or hiatus between two +phenomena (non datur hiatus)--for we can so express the principle, that +experience can admit nothing which proves the existence of a vacuum, or +which even admits it as a part of an empirical synthesis. For, as +regards a vacuum or void, which we may cogitate as out and beyond the +field of possible experience (the world), such a question cannot come +before the tribunal of mere understanding, which decides only upon +questions that concern the employment of given phenomena for the +construction of empirical cognition. It is rather a problem for ideal +reason, which passes beyond the sphere of a possible experience and +aims at forming a judgement of that which surrounds and circumscribes +it, and the proper place for the consideration of it is the +transcendental dialectic. These four propositions, "In mundo non datur +hiatus, non datur saltus, non datur casus, non datur fatum," as well as +all principles of transcendental origin, we could very easily exhibit +in their proper order, that is, in conformity with the order of the +categories, and assign to each its proper place. But the already +practised reader will do this for himself, or discover the clue to such +an arrangement. But the combined result of all is simply this, to admit +into the empirical synthesis nothing which might cause a break in or be +foreign to the understanding and the continuous connection of all +phenomena, that is, the unity of the conceptions of the understanding. +For in the understanding alone is the unity of experience, in which all +perceptions must have their assigned place, possible. + +Whether the field of possibility be greater than that of reality, and +whether the field of the latter be itself greater than that of +necessity, are interesting enough questions, and quite capable of +synthetic solution, questions, however, which come under the +jurisdiction of reason alone. For they are tantamount to asking whether +all things as phenomena do without exception belong to the complex and +connected whole of a single experience, of which every given perception +is a part which therefore cannot be conjoined with any other +phenomena--or, whether my perceptions can belong to more than one +possible experience? The understanding gives to experience, according +to the subjective and formal conditions, of sensibility as well as of +apperception, the rules which alone make this experience possible. +Other forms of intuition besides those of space and time, other forms +of understanding besides the discursive forms of thought, or of +cognition by means of conceptions, we can neither imagine nor make +intelligible to ourselves; and even if we could, they would still not +belong to experience, which is the only mode of cognition by which +objects are presented to us. Whether other perceptions besides those +which belong to the total of our possible experience, and consequently +whether some other sphere of matter exists, the understanding has no +power to decide, its proper occupation being with the synthesis of that +which is given. Moreover, the poverty of the usual arguments which go +to prove the existence of a vast sphere of possibility, of which all +that is real (every object of experience) is but a small part, is very +remarkable. "All real is possible"; from this follows naturally, +according to the logical laws of conversion, the particular +proposition: "Some possible is real." Now this seems to be equivalent +to: "Much is possible that is not real." No doubt it does seem as if we +ought to consider the sum of the possible to be greater than that of +the real, from the fact that something must be added to the former to +constitute the latter. But this notion of adding to the possible is +absurd. For that which is not in the sum of the possible, and +consequently requires to be added to it, is manifestly impossible. In +addition to accordance with the formal conditions of experience, the +understanding requires a connection with some perception; but that +which is connected with this perception is real, even although it is +not immediately perceived. But that another series of phenomena, in +complete coherence with that which is given in perception, consequently +more than one all-embracing experience is possible, is an inference +which cannot be concluded from the data given us by experience, and +still less without any data at all. That which is possible only under +conditions which are themselves merely possible, is not possible in any +respect. And yet we can find no more certain ground on which to base +the discussion of the question whether the sphere of possibility is +wider than that of experience. + +I have merely mentioned these questions, that in treating of the +conception of the understanding, there might be no omission of +anything that, in the common opinion, belongs to them. In reality, +however, the notion of absolute possibility (possibility which is +valid in every respect) is not a mere conception of the understanding, +which can be employed empirically, but belongs to reason alone, +which passes the bounds of all empirical use of the understanding. +We have, therefore, contented ourselves with a merely critical remark, +leaving the subject to be explained in the sequel. + +Before concluding this fourth section, and at the same time the system +of all principles of the pure understanding, it seems proper to mention +the reasons which induced me to term the principles of modality +postulates. This expression I do not here use in the sense which some +more recent philosophers, contrary to its meaning with mathematicians, +to whom the word properly belongs, attach to it--that of a +proposition, namely, immediately certain, requiring neither deduction +nor proof. For if, in the case of synthetical propositions, however +evident they may be, we accord to them without deduction, and merely on +the strength of their own pretensions, unqualified belief, all critique +of the understanding is entirely lost; and, as there is no want of bold +pretensions, which the common belief (though for the philosopher this +is no credential) does not reject, the understanding lies exposed to +every delusion and conceit, without the power of refusing its assent to +those assertions, which, though illegitimate, demand acceptance as +veritable axioms. When, therefore, to the conception of a thing an a +priori determination is synthetically added, such a proposition must +obtain, if not a proof, at least a deduction of the legitimacy of its +assertion. + +The principles of modality are, however, not objectively +synthetical, for the predicates of possibility, reality, and necessity +do not in the least augment the conception of that of which they are +affirmed, inasmuch as they contribute nothing to the representation +of the object. But as they are, nevertheless, always synthetical, they +are so merely subjectively. That is to say, they have a reflective +power, and apply to the conception of a thing, of which, in other +respects, they affirm nothing, the faculty of cognition in which the +conception originates and has its seat. So that if the conception +merely agree with the formal conditions of experience, its object is +called possible; if it is in connection with perception, and +determined thereby, the object is real; if it is determined +according to conceptions by means of the connection of perceptions, +the object is called necessary. The principles of modality therefore +predicate of a conception nothing more than the procedure of the +faculty of cognition which generated it. Now a postulate in +mathematics is a practical proposition which contains nothing but +the synthesis by which we present an object to ourselves, and +produce the conception of it, for example--"With a given line, to +describe a circle upon a plane, from a given point"; and such a +proposition does not admit of proof, because the procedure, which it +requires, is exactly that by which alone it is possible to generate +the conception of such a figure. With the same right, accordingly, +can we postulate the principles of modality, because they do not +augment* the conception of a thing but merely indicate the manner in +which it is connected with the faculty of cognition. + +[*Footnote: When I think the reality of a thing, I do really think +more than the possibility, but not in the thing; for that can never +contain more in reality than was contained in its complete possibility. +But while the notion of possibility is merely the notion of a position +of thing in relation to the understanding (its empirical use), reality +is the conjunction of the thing with perception.] + + + +GENERAL REMARK ON THE SYSTEM OF PRINCIPLES. + +It is very remarkable that we cannot perceive the possibility of a +thing from the category alone, but must always have an intuition, by +which to make evident the objective reality of the pure conception +of the understanding. Take, for example, the categories of relation. +How (1) a thing can exist only as a subject, and not as a mere +determination of other things, that is, can be substance; or how +(2), because something exists, some other thing must exist, +consequently how a thing can be a cause; or how (3), when several +things exist, from the fact that one of these things exists, some +consequence to the others follows, and reciprocally, and in this way +a community of substances can be possible--are questions whose +solution cannot be obtained from mere conceptions. The very same is +the case with the other categories; for example, how a thing can be +of the same sort with many others, that is, can be a quantity, and +so on. So long as we have not intuition we cannot know whether we do +really think an object by the categories, and where an object can anywhere +be found to cohere with them, and thus the truth is established, that +the categories are not in themselves cognitions, but mere forms of +thought for the construction of cognitions from given intuitions. For +the same reason is it true that from categories alone no synthetical +proposition can be made. For example: "In every existence there is +substance," that is, something that can exist only as a subject and +not as mere predicate; or, "Everything is a quantity"--to construct +propositions such as these, we require something to enable us to go +out beyond the given conception and connect another with it. For the +same reason the attempt to prove a synthetical proposition by means +of mere conceptions, for example: "Everything that exists contingently +has a cause," has never succeeded. We could never get further than +proving that, without this relation to conceptions, we could not +conceive the existence of the contingent, that is, could not a +priori through the understanding cognize the existence of such a +thing; but it does not hence follow that this is also the condition +of the possibility of the thing itself that is said to be contingent. +If, accordingly; we look back to our proof of the principle of +causality, we shall find that we were able to prove it as valid only +of objects of possible experience, and, indeed, only as itself the +principle of the possibility of experience, Consequently of the +cognition of an object given in empirical intuition, and not from mere +conceptions. That, however, the proposition: "Everything that is +contingent must have a cause," is evident to every one merely from +conceptions, is not to be denied. But in this case the conception of +the contingent is cogitated as involving not the category of +modality (as that the non-existence of which can be conceived) but +that of relation (as that which can exist only as the consequence of +something else), and so it is really an identical proposition: "That +which can exist only as a consequence, has a cause." In fact, when +we have to give examples of contingent existence, we always refer to +changes, and not merely to the possibility of conceiving the +opposite.* But change is an event, which, as such, is possible only +through a cause, and considered per se its non-existence is +therefore possible, and we become cognizant of its contingency from +the fact that it can exist only as the effect of a cause. Hence, if +a thing is assumed to be contingent, it is an analytical proposition +to say, it has a cause. + +[*Footnote: We can easily conceive the non-existence of matter; but +the ancients did not thence infer its contingency. But even the +alternation of the existence and non-existence of a given state in +a thing, in which all change consists, by no means proves the +contingency of that state--the ground of proof being the reality of +its opposite. For example, a body is in a state of rest after +motion, but we cannot infer the contingency of the motion from the +fact that the former is the opposite of the latter. For this +opposite is merely a logical and not a real opposite to the other. +If we wish to demonstrate the contingency of the motion, what we ought +to prove is that, instead of the motion which took place in the +preceding point of time, it was possible for the body to have been +then in rest, not, that it is afterwards in rest; for in this case, +both opposites are perfectly consistent with each other.] + +But it is still more remarkable that, to understand the possibility of +things according to the categories and thus to demonstrate the +objective reality of the latter, we require not merely intuitions, but +external intuitions. If, for example, we take the pure conceptions of +relation, we find that (1) for the purpose of presenting to the +conception of substance something permanent in intuition corresponding +thereto and thus of demonstrating the objective reality of this +conception, we require an intuition (of matter) in space, because space +alone is permanent and determines things as such, while time, and with +it all that is in the internal sense, is in a state of continual flow; +(2) in order to represent change as the intuition corresponding to the +conception of causality, we require the representation of motion as +change in space; in fact, it is through it alone that changes, the +possibility of which no pure understanding can perceive, are capable of +being intuited. Change is the connection of determinations +contradictorily opposed to each other in the existence of one and the +same thing. Now, how it is possible that out of a given state one quite +opposite to it in the same thing should follow, reason without an +example can not only not conceive, but cannot even make intelligible +without intuition; and this intuition is the motion of a point in +space; the existence of which in different spaces (as a consequence of +opposite determinations) alone makes the intuition of change possible. +For, in order to make even internal change cognitable, we require to +represent time, as the form of the internal sense, figuratively by a +line, and the internal change by the drawing of that line (motion), and +consequently are obliged to employ external intuition to be able to +represent the successive existence of ourselves in different states. +The proper ground of this fact is that all change to be perceived as +change presupposes something permanent in intuition, while in the +internal sense no permanent intuition is to be found. Lastly, the +objective possibility of the category of community cannot be conceived +by mere reason, and consequently its objective reality cannot be +demonstrated without an intuition, and that external in space. For how +can we conceive the possibility of community, that is, when several +substances exist, that some effect on the existence of the one follows +from the existence of the other, and reciprocally, and therefore that, +because something exists in the latter, something else must exist in +the former, which could not be understood from its own existence alone? +For this is the very essence of community--which is inconceivable as a +property of things which are perfectly isolated. Hence, Leibnitz, in +attributing to the substances of the world--as cogitated by the +understanding alone--a community, required the mediating aid of a +divinity; for, from their existence, such a property seemed to him with +justice inconceivable. But we can very easily conceive the possibility +of community (of substances as phenomena) if we represent them to +ourselves as in space, consequently in external intuition. For external +intuition contains in itself a priori formal external relations, as the +conditions of the possibility of the real relations of action and +reaction, and therefore of the possibility of community. With the same +ease can it be demonstrated, that the possibility of things as +quantities, and consequently the objective reality of the category of +quantity, can be grounded only in external intuition, and that by its +means alone is the notion of quantity appropriated by the internal +sense. But I must avoid prolixity, and leave the task of illustrating +this by examples to the reader's own reflection. + +The above remarks are of the greatest importance, not only for the +confirmation of our previous confutation of idealism, but still more +when the subject of self-cognition by mere internal consciousness +and the determination of our own nature without the aid of external +empirical intuitions is under discussion, for the indication of the +grounds of the possibility of such a cognition. + +The result of the whole of this part of the analytic of principles +is, therefore: "All principles of the pure understanding are nothing +more than a priori principles of the possibility of experience, and +to experience alone do all a priori synthetical propositions apply +and relate"; indeed, their possibility itself rests entirely on this +relation. + + + +CHAPTER III Of the Ground of the Division of all Objects into Phenomena + and Noumena. + +We have now not only traversed the region of the pure +understanding and carefully surveyed every part of it, but we have +also measured it, and assigned to everything therein its proper place. +But this land is an island, and enclosed by nature herself within +unchangeable limits. It is the land of truth (an attractive word), +surrounded by a wide and stormy ocean, the region of illusion, where +many a fog-bank, many an iceberg, seems to the mariner, on his +voyage of discovery, a new country, and, while constantly deluding +him with vain hopes, engages him in dangerous adventures, from which +he never can desist, and which yet he never can bring to a termination. +But before venturing upon this sea, in order to explore it in its +whole extent, and to arrive at a certainty whether anything is to be +discovered there, it will not be without advantage if we cast our eyes +upon the chart of the land that we are about to leave, and to ask +ourselves, firstly, whether we cannot rest perfectly contented with +what it contains, or whether we must not of necessity be contented +with it, if we can find nowhere else a solid foundation to build upon; +and, secondly, by what title we possess this land itself, and how we +hold it secure against all hostile claims? Although, in the course +of our analytic, we have already given sufficient answers to these +questions, yet a summary recapitulation of these solutions may be +useful in strengthening our conviction, by uniting in one point the +momenta of the arguments. + +We have seen that everything which the understanding draws from +itself, without borrowing from experience, it nevertheless possesses +only for the behoof and use of experience. The principles of the +pure understanding, whether constitutive a priori (as the mathematical +principles), or merely regulative (as the dynamical), contain +nothing but the pure schema, as it were, of possible experience. For +experience possesses its unity from the synthetical unity which the +understanding, originally and from itself, imparts to the synthesis +of the imagination in relation to apperception, and in a priori +relation to and agreement with which phenomena, as data for a possible +cognition, must stand. But although these rules of the understanding +are not only a priori true, but the very source of all truth, that +is, of the accordance of our cognition with objects, and on this ground, +that they contain the basis of the possibility of experience, as the +ensemble of all cognition, it seems to us not enough to propound +what is true--we desire also to be told what we want to know. If, +then, we learn nothing more by this critical examination than what +we should have practised in the merely empirical use of the +understanding, without any such subtle inquiry, the presumption is +that the advantage we reap from it is not worth the labour bestowed +upon it. It may certainly be answered that no rash curiosity is more +prejudicial to the enlargement of our knowledge than that which must +know beforehand the utility of this or that piece of information which +we seek, before we have entered on the needful investigations, and +before one could form the least conception of its utility, even though +it were placed before our eyes. But there is one advantage in such +transcendental inquiries which can be made comprehensible to the +dullest and most reluctant learner--this, namely, that the +understanding which is occupied merely with empirical exercise, and +does not reflect on the sources of its own cognition, may exercise +its functions very well and very successfully, but is quite unable +to do one thing, and that of very great importance, to determine, namely, +the bounds that limit its employment, and to know what lies within +or without its own sphere. This purpose can be obtained only by such +profound investigations as we have instituted. But if it cannot +distinguish whether certain questions lie within its horizon or not, +it can never be sure either as to its claims or possessions, but +must lay its account with many humiliating corrections, when it +transgresses, as it unavoidably will, the limits of its own territory, +and loses itself in fanciful opinions and blinding illusions. + +That the understanding, therefore, cannot make of its a priori +principles, or even of its conceptions, other than an empirical use, +is a proposition which leads to the most important results. A +transcendental use is made of a conception in a fundamental +proposition or principle, when it is referred to things in general +and considered as things in themselves; an empirical use, when it is +referred merely to phenomena, that is, to objects of a possible +experience. That the latter use of a conception is the only admissible +one is evident from the reasons following. For every conception are +requisite, firstly, the logical form of a conception (of thought) +general; and, secondly, the possibility of presenting to this an +object to which it may apply. Failing this latter, it has no sense, +and utterly void of content, although it may contain the logical +function for constructing a conception from certain data. Now, +object cannot be given to a conception otherwise than by intuition, +and, even if a pure intuition antecedent to the object is a priori +possible, this pure intuition can itself obtain objective validity +only from empirical intuition, of which it is itself but the form. +All conceptions, therefore, and with them all principles, however high +the degree of their a priori possibility, relate to empirical +intuitions, that is, to data towards a possible experience. Without +this they possess no objective validity, but are mere play of +imagination or of understanding with images or notions. Let us take, +for example, the conceptions of mathematics, and first in its pure +intuitions. "Space has three dimensions"--"Between two points there +can be only one straight line," etc. Although all these principles, +and the representation of the object with which this science +occupies itself, are generated in the mind entirely a priori, they +would nevertheless have no significance if we were not always able +to exhibit their significance in and by means of phenomena +(empirical objects). Hence it is requisite that an abstract conception +be made sensuous, that is, that an object corresponding to it in +intuition be forthcoming, otherwise the conception remains, as we say, +without sense, that is, without meaning. Mathematics fulfils this +requirement by the construction of the figure, which is a phenomenon +evident to the senses. The same science finds support and significance +in number; this in its turn finds it in the fingers, or in counters, +or in lines and points. The conception itself is always produced a +priori, together with the synthetical principles or formulas from such +conceptions; but the proper employment of them, and their +application to objects, can exist nowhere but in experience, the +possibility of which, as regards its form, they contain a priori. + +That this is also the case with all of the categories and the +principles based upon them is evident from the fact that we cannot +render intelligible the possibility of an object corresponding to them +without having recourse to the conditions of sensibility, +consequently, to the form of phenomena, to which, as their only proper +objects, their use must therefore be confined, inasmuch as, if this +condition is removed, all significance, that is, all relation to an +object, disappears, and no example can be found to make it +comprehensible what sort of things we ought to think under such +conceptions. + +The conception of quantity cannot be explained except by saying that +it is the determination of a thing whereby it can be cogitated how +many times one is placed in it. But this "how many times" is based +upon successive repetition, consequently upon time and the synthesis +of the homogeneous therein. Reality, in contradistinction to negation, +can be explained only by cogitating a time which is either filled +therewith or is void. If I leave out the notion of permanence (which +is existence in all time), there remains in the conception of +substance nothing but the logical notion of subject, a notion of which +I endeavour to realize by representing to myself something that can +exist only as a subject. But not only am I perfectly ignorant of any +conditions under which this logical prerogative can belong to a thing, +I can make nothing out of the notion, and draw no inference from it, +because no object to which to apply the conception is determined, +and we consequently do not know whether it has any meaning at all. +In like manner, if I leave out the notion of time, in which +something follows upon some other thing in conformity with a rule, +I can find nothing in the pure category, except that there is a +something of such a sort that from it a conclusion may be drawn as +to the existence of some other thing. But in this case it would not +only be impossible to distinguish between a cause and an effect, +but, as this power to draw conclusions requires conditions of which +I am quite ignorant, the conception is not determined as to the mode +in which it ought to apply to an object. The so-called principle: +"Everything that is contingent has a cause," comes with a gravity +and self-assumed authority that seems to require no support from +without. But, I ask, what is meant by contingent? The answer is that +the non-existence of which is possible. But I should like very well +to know by what means this possibility of non-existence is to be +cognized, if we do not represent to ourselves a succession in the +series of phenomena, and in this succession an existence which follows +a non-existence, or conversely, consequently, change. For to say, that +the non-existence of a thing is not self-contradictory is a lame +appeal to a logical condition, which is no doubt a necessary condition +of the existence of the conception, but is far from being sufficient +for the real objective possibility of non-existence. I can +annihilate in thought every existing substance without +self-contradiction, but I cannot infer from this their objective +contingency in existence, that is to say, the possibility of their +non-existence in itself. As regards the category of community, it +may easily be inferred that, as the pure categories of substance and +causality are incapable of a definition and explanation sufficient +to determine their object without the aid of intuition, the category +of reciprocal causality in the relation of substances to each other +(commercium) is just as little susceptible thereof. Possibility, +existence, and necessity nobody has ever yet been able to explain +without being guilty of manifest tautology, when the definition has +been drawn entirely from the pure understanding. For the +substitution of the logical possibility of the conception--the +condition of which is that it be not self-contradictory, for the +transcendental possibility of things--the condition of which is that +there be an object corresponding to the conception, is a trick which +can only deceive the inexperienced.* + +[*Footnote: In one word, to none of these conceptions belongs a +corresponding object, and consequently their real possibility cannot +be demonstrated, if we take away sensuous intuition--the only intuition +which we possess--and there then remains nothing but the logical +possibility, that is, the fact that the conception or thought is +possible--which, however, is not the question; what we want to know +being, whether it relates to an object and thus possesses any meaning.] + +It follows incontestably, that the pure conceptions of the +understanding are incapable of transcendental, and must always be of +empirical use alone, and that the principles of the pure understanding +relate only to the general conditions of a possible experience, to +objects of the senses, and never to things in general, apart from +the mode in which we intuite them. + +Transcendental analytic has accordingly this important result, to +wit, that the understanding is competent' effect nothing a priori, +except the anticipation of the form of a possible experience in +general, and that, as that which is not phenomenon cannot be an object +of experience, it can never overstep the limits of sensibility, within +which alone objects are presented to us. Its principles are merely +principles of the exposition of phenomena, and the proud name of an +ontology, which professes to present synthetical cognitions a priori +of things in general in a systematic doctrine, must give place to +the modest title of analytic of the pure understanding. + +Thought is the act of referring a given intuition to an object. If +the mode of this intuition is unknown to us, the object is merely +transcendental, and the conception of the understanding is employed +only transcendentally, that is, to produce unity in the thought of +a manifold in general. Now a pure category, in which all conditions +of sensuous intuition--as the only intuition we possess--are +abstracted, does not determine an object, but merely expresses the +thought of an object in general, according to different modes. Now, +to employ a conception, the function of judgement is required, by which +an object is subsumed under the conception, consequently the at +least formal condition, under which something can be given in +intuition. Failing this condition of judgement (schema), subsumption +is impossible; for there is in such a case nothing given, which may +be subsumed under the conception. The merely transcendental use of +the categories is therefore, in fact, no use at all and has no determined, +or even, as regards its form, determinable object. Hence it follows +that the pure category is incompetent to establish a synthetical a +priori principle, and that the principles of the pure understanding +are only of empirical and never of transcendental use, and that beyond +the sphere of possible experience no synthetical a priori principles +are possible. + +It may be advisable, therefore, to express ourselves thus. The +pure categories, apart from the formal conditions of sensibility, have +a merely transcendental meaning, but are nevertheless not of +transcendental use, because this is in itself impossible, inasmuch +as all the conditions of any employment or use of them (in judgements) +are absent, to wit, the formal conditions of the subsumption of an +object under these conceptions. As, therefore, in the character of +pure categories, they must be employed empirically, and cannot be +employed transcendentally, they are of no use at all, when separated +from sensibility, that is, they cannot be applied to an object. They +are merely the pure form of the employment of the understanding in +respect of objects in general and of thought, without its being at +the same time possible to think or to determine any object by their +means. But there lurks at the foundation of this subject an illusion +which it is very difficult to avoid. The categories are not based, +as regards their origin, upon sensibility, like the forms of +intuition, space, and time; they seem, therefore, to be capable of +an application beyond the sphere of sensuous objects. But this is +not the case. They are nothing but mere forms of thought, which +contain only the logical faculty of uniting a priori in +consciousness the manifold given in intuition. Apart, then, from the +only intuition possible for us, they have still less meaning than +the pure sensuous forms, space and time, for through them an object +is at least given, while a mode of connection of the manifold, when +the intuition which alone gives the manifold is wanting, has no meaning +at all. At the same time, when we designate certain objects as +phenomena or sensuous existences, thus distinguishing our mode of +intuiting them from their own nature as things in themselves, it is +evident that by this very distinction we as it were place the +latter, considered in this their own nature, although we do not so +intuite them, in opposition to the former, or, on the other hand, we +do so place other possible things, which are not objects of our +senses, but are cogitated by the understanding alone, and call them +intelligible existences (noumena). Now the question arises whether +the pure conceptions of our understanding do possess significance in +respect of these latter, and may possibly be a mode of cognizing them. + +But we are met at the very commencement with an ambiguity, which may +easily occasion great misapprehension. The understanding, when it +terms an object in a certain relation phenomenon, at the same time +forms out of this relation a representation or notion of an object +in itself, and hence believes that it can form also conceptions of +such objects. Now as the understanding possesses no other +fundamental conceptions besides the categories, it takes for granted +that an object considered as a thing in itself must be capable of +being thought by means of these pure conceptions, and is thereby led +to hold the perfectly undetermined conception of an intelligible +existence, a something out of the sphere of our sensibility, for a +determinate conception of an existence which we can cognize in some +way or other by means of the understanding. + +If, by the term noumenon, we understand a thing so far as it is +not an object of our sensuous intuition, thus making abstraction of +our mode of intuiting it, this is a noumenon in the negative sense +of the word. But if we understand by it an object of a non-sensuous +intuition, we in this case assume a peculiar mode of intuition, an +intellectual intuition, to wit, which does not, however, belong to +us, of the very possibility of which we have no notion--and this is +a noumenon in the positive sense. + +The doctrine of sensibility is also the doctrine of noumena in the +negative sense, that is, of things which the understanding is +obliged to cogitate apart from any relation to our mode of +intuition, consequently not as mere phenomena, but as things in +themselves. But the understanding at the same time comprehends that +it cannot employ its categories for the consideration of things in +themselves, because these possess significance only in relation to +the unity of intuitions in space and time, and that they are competent +to determine this unity by means of general a priori connecting +conceptions only on account of the pure ideality of space and time. +Where this unity of time is not to be met with, as is the case with +noumena, the whole use, indeed the whole meaning of the categories +is entirely lost, for even the possibility of things to correspond +to the categories is in this case incomprehensible. On this point, +I need only refer the reader to what I have said at the commencement +of the General Remark appended to the foregoing chapter. Now, the +possibility of a thing can never be proved from the fact that the +conception of it is not self-contradictory, but only by means of an +intuition corresponding to the conception. If, therefore, we wish to +apply the categories to objects which cannot be regarded as phenomena, +we must have an intuition different from the sensuous, and in this +case the objects would be a noumena in the positive sense of the word. +Now, as such an intuition, that is, an intellectual intuition, is no +part of our faculty of cognition, it is absolutely impossible for +the categories to possess any application beyond the limits of +experience. It may be true that there are intelligible existences to +which our faculty of sensuous intuition has no relation, and cannot +be applied, but our conceptions of the understanding, as mere forms +of thought for our sensuous intuition, do not extend to these. What, +therefore, we call noumenon must be understood by us as such in a +negative sense. + +If I take away from an empirical intuition all thought (by means of +the categories), there remains no cognition of any object; for by +means of mere intuition nothing is cogitated, and, from the +existence of such or such an affection of sensibility in me, it does +not follow that this affection or representation has any relation to +an object without me. But if I take away all intuition, there still +remains the form of thought, that is, the mode of determining an +object for the manifold of a possible intuition. Thus the categories +do in some measure really extend further than sensuous intuition, +inasmuch as they think objects in general, without regard to the +mode (of sensibility) in which these objects are given. But they do +not for this reason apply to and determine a wider sphere of +objects, because we cannot assume that such can be given, without +presupposing the possibility of another than the sensuous mode of +intuition, a supposition we are not justified in making. + +I call a conception problematical which contains in itself no +contradiction, and which is connected with other cognitions as a +limitation of given conceptions, but whose objective reality cannot +be cognized in any manner. The conception of a noumenon, that is, of +a thing which must be cogitated not as an object of sense, but as a +thing in itself (solely through the pure understanding), is not +self-contradictory, for we are not entitled to maintain that +sensibility is the only possible mode of intuition. Nay, further, this +conception is necessary to restrain sensuous intuition within the +bounds of phenomena, and thus to limit the objective validity of +sensuous cognition; for things in themselves, which lie beyond its +province, are called noumena for the very purpose of indicating that +this cognition does not extend its application to all that the +understanding thinks. But, after all, the possibility of such +noumena is quite incomprehensible, and beyond the sphere of phenomena, +all is for us a mere void; that is to say, we possess an understanding +whose province does problematically extend beyond this sphere, but +we do not possess an intuition, indeed, not even the conception of +a possible intuition, by means of which objects beyond the region of +sensibility could be given us, and in reference to which the +understanding might be employed assertorically. The conception of a +noumenon is therefore merely a limitative conception and therefore +only of negative use. But it is not an arbitrary or fictitious notion, +but is connected with the limitation of sensibility, without, however, +being capable of presenting us with any positive datum beyond this +sphere. + +The division of objects into phenomena and noumena, and of the world +into a mundus sensibilis and intelligibilis is therefore quite +inadmissible in a positive sense, although conceptions do certainly +admit of such a division; for the class of noumena have no determinate +object corresponding to them, and cannot therefore possess objective +validity. If we abandon the senses, how can it be made conceivable +that the categories (which are the only conceptions that could serve +as conceptions for noumena) have any sense or meaning at all, inasmuch +as something more than the mere unity of thought, namely, a possible +intuition, is requisite for their application to an object? The +conception of a noumenon, considered as merely problematical, is, +however, not only admissible, but, as a limitative conception of +sensibility, absolutely necessary. But, in this case, a noumenon is +not a particular intelligible object for our understanding; on the +contrary, the kind of understanding to which it could belong is itself +a problem, for we cannot form the most distant conception of the +possibility of an understanding which should cognize an object, not +discursively by means of categories, but intuitively in a non-sensuous +intuition. Our understanding attains in this way a sort of negative +extension. That is to say, it is not limited by, but rather limits, +sensibility, by giving the name of noumena to things, not considered +as phenomena, but as things in themselves. But it at the same time +prescribes limits to itself, for it confesses itself unable to cognize +these by means of the categories, and hence is compelled to cogitate +them merely as an unknown something. + +I find, however, in the writings of modern authors, an entirely +different use of the expressions, mundus sensibilis and +intelligibilis, which quite departs from the meaning of the +ancients--an acceptation in which, indeed, there is to be found no +difficulty, but which at the same time depends on mere verbal +quibbling. According to this meaning, some have chosen to call the +complex of phenomena, in so far as it is intuited, mundus +sensibilis, but in so far as the connection thereof is cogitated +according to general laws of thought, mundus intelligibilis. +Astronomy, in so far as we mean by the word the mere observation of +the starry heaven, may represent the former; a system of astronomy, +such as the Copernican or Newtonian, the latter. But such twisting +of words is a mere sophistical subterfuge, to avoid a difficult +question, by modifying its meaning to suit our own convenience. To +be sure, understanding and reason are employed in the cognition of +phenomena; but the question is, whether these can be applied when +the object is not a phenomenon and in this sense we regard it if it +is cogitated as given to the understanding alone, and not to the +senses. The question therefore is whether, over and above the +empirical use of the understanding, a transcendental use is +possible, which applies to the noumenon as an object. This question +we have answered in the negative. + +When therefore we say, the senses represent objects as they +appear, the understanding as they are, the latter statement must not +be understood in a transcendental, but only in an empirical +signification, that is, as they must be represented in the complete +connection of phenomena, and not according to what they may be, +apart from their relation to possible experience, consequently not +as objects of the pure understanding. For this must ever remain +unknown to us. Nay, it is also quite unknown to us whether any such +transcendental or extraordinary cognition is possible under any +circumstances, at least, whether it is possible by means of our +categories. Understanding and sensibility, with us, can determine +objects only in conjunction. If we separate them, we have intuitions +without conceptions, or conceptions without intuitions; in both cases, +representations, which we cannot apply to any determinate object. + +If, after all our inquiries and explanations, any one still +hesitates to abandon the mere transcendental use of the categories, +let him attempt to construct with them a synthetical proposition. It +would, of course, be unnecessary for this purpose to construct an +analytical proposition, for that does not extend the sphere of the +understanding, but, being concerned only about what is cogitated in +the conception itself, it leaves it quite undecided whether the +conception has any relation to objects, or merely indicates the +unity of thought--complete abstraction being made of the modi in which +an object may be given: in such a proposition, it is sufficient for +the understanding to know what lies in the conception--to what it +applies is to it indifferent. The attempt must therefore be made +with a synthetical and so-called transcendental principle, for +example: "Everything that exists, exists as substance," or, +"Everything that is contingent exists as an effect of some other +thing, viz., of its cause." Now I ask, whence can the understanding +draw these synthetical propositions, when the conceptions contained +therein do not relate to possible experience but to things in +themselves (noumena)? Where is to be found the third term, which is +always requisite PURE site in a synthetical proposition, which may +connect in the same proposition conceptions which have no logical +(analytical) connection with each other? The proposition never will +be demonstrated, nay, more, the possibility of any such pure assertion +never can be shown, without making reference to the empirical use of +the understanding, and thus, ipso facto, completely renouncing pure +and non-sensuous judgement. Thus the conception of pure and merely +intelligible objects is completely void of all principles of its +application, because we cannot imagine any mode in which they might +be given, and the problematical thought which leaves a place open for +them serves only, like a void space, to limit the use of empirical +principles, without containing at the same time any other object of +cognition beyond their sphere. + + + + +APPENDIX. + +Of the Equivocal Nature or Amphiboly of the Conceptions of +Reflection from the Confusion of the Transcendental with +the Empirical use of the Understanding. + +Reflection (reflexio) is not occupied about objects themselves, +for the purpose of directly obtaining conceptions of them, but is that +state of the mind in which we set ourselves to discover the subjective +conditions under which we obtain conceptions. It is the +consciousness of the relation of given representations to the +different sources or faculties of cognition, by which alone their +relation to each other can be rightly determined. The first question +which occurs in considering our representations is to what faculty +of cognition do they belong? To the understanding or to the senses? +Many judgements are admitted to be true from mere habit or +inclination; but, because reflection neither precedes nor follows, +it is held to be a judgement that has its origin in the understanding. +All judgements do not require examination, that is, investigation into +the grounds of their truth. For, when they are immediately certain +(for example: "Between two points there can be only one straight +line"), no better or less mediate test of their truth can be found +than that which they themselves contain and express. But all +judgement, nay, all comparisons require reflection, that is, a +distinction of the faculty of cognition to which the given conceptions +belong. The act whereby I compare my representations with the +faculty of cognition which originates them, and whereby I +distinguish whether they are compared with each other as belonging +to the pure understanding or to sensuous intuition, I term +transcendental reflection. Now, the relations in which conceptions +can stand to each other are those of identity and difference, agreement +and opposition, of the internal and external, finally, of the +determinable and the determining (matter and form). The proper +determination of these relations rests on the question, to what +faculty of cognition they subjectively belong, whether to +sensibility or understanding? For, on the manner in which we solve +this question depends the manner in which we must cogitate these +relations. + +Before constructing any objective judgement, we compare the +conceptions that are to be placed in the judgement, and observe +whether there exists identity (of many representations in one +conception), if a general judgement is to be constructed, or +difference, if a particular; whether there is agreement when +affirmative; and opposition when negative judgements are to be +constructed, and so on. For this reason we ought to call these +conceptions, conceptions of comparison (conceptus comparationis). +But as, when the question is not as to the logical form, but as to +the content of conceptions, that is to say, whether the things +themselves are identical or different, in agreement or opposition, +and so on, the things can have a twofold relation to our faculty of +cognition, to wit, a relation either to sensibility or to the +understanding, and as on this relation depends their relation to +each other, transcendental reflection, that is, the relation of +given representations to one or the other faculty of cognition, can +alone determine this latter relation. Thus we shall not be able to +discover whether the things are identical or different, in agreement +or opposition, etc., from the mere conception of the things by means +of comparison (comparatio), but only by distinguishing the mode of +cognition to which they belong, in other words, by means of +transcendental reflection. We may, therefore, with justice say, that +logical reflection is mere comparison, for in it no account is taken +of the faculty of cognition to which the given conceptions belong, +and they are consequently, as far as regards their origin, to be treated +as homogeneous; while transcendental reflection (which applies to +the objects themselves) contains the ground of the possibility of +objective comparison of representations with each other, and is +therefore very different from the former, because the faculties of +cognition to which they belong are not even the same. Transcendental +reflection is a duty which no one can neglect who wishes to +establish an a priori judgement upon things. We shall now proceed to +fulfil this duty, and thereby throw not a little light on the question +as to the determination of the proper business of the understanding. + +1. Identity and Difference. When an object is presented to us +several times, but always with the same internal determinations +(qualitas et quantitas), it, if an object of pure understanding, is +always the same, not several things, but only one thing (numerica +identitas); but if a phenomenon, we do not concern ourselves with +comparing the conception of the thing with the conception of some +other, but, although they may be in this respect perfectly the same, +the difference of place at the same time is a sufficient ground for +asserting the numerical difference of these objects (of sense). +Thus, in the case of two drops of water, we may make complete +abstraction of all internal difference (quality and quantity), and, +the fact that they are intuited at the same time in different +places, is sufficient to justify us in holding them to be +numerically different. Leibnitz regarded phenomena as things in +themselves, consequently as intelligibilia, that is, objects of pure +understanding (although, on account of the confused nature of their +representations, he gave them the name of phenomena), and in this case +his principle of the indiscernible (principium identatis +indiscernibilium) is not to be impugned. But, as phenomena are objects +of sensibility, and, as the understanding, in respect of them, must +be employed empirically and not purely or transcendentally, plurality +and numerical difference are given by space itself as the condition +of external phenomena. For one part of space, although it may be +perfectly similar and equal to another part, is still without it, +and for this reason alone is different from the latter, which is added +to it in order to make up a greater space. It follows that this must +hold good of all things that are in the different parts of space at +the same time, however similar and equal one may be to another. + +2. Agreement and Opposition. When reality is represented by the pure +understanding (realitas noumenon), opposition between realities is +incogitable--such a relation, that is, that when these realities are +connected in one subject, they annihilate the effects of each other +and may be represented in the formula 3 - 3 = 0. On the other hand, +the real in a phenomenon (realitas phaenomenon) may very well be in +mutual opposition, and, when united in the same subject, the one may +completely or in part annihilate the effect or consequence of the +other; as in the case of two moving forces in the same straight line +drawing or impelling a point in opposite directions, or in the case +of a pleasure counterbalancing a certain amount of pain. + +3. The Internal and External. In an object of the pure +understanding, only that is internal which has no relation (as regards +its existence) to anything different from itself. On the other hand, +the internal determinations of a substantia phaenomenon in space are +nothing but relations, and it is itself nothing more than a complex +of mere relations. Substance in space we are cognizant of only through +forces operative in it, either drawing others towards itself +(attraction), or preventing others from forcing into itself (repulsion +and impenetrability). We know no other properties that make up the +conception of substance phenomenal in space, and which we term matter. +On the other hand, as an object of the pure understanding, every +substance must have internal determination and forces. But what +other internal attributes of such an object can I think than those +which my internal sense presents to me? That, to wit, which in +either itself thought, or something analogous to it. Hence Leibnitz, +who looked upon things as noumena, after denying them everything +like external relation, and therefore also composition or combination, +declared that all substances, even the component parts of matter, were +simple substances with powers of representation, in one word, monads. + +4. Matter and Form. These two conceptions lie at the foundation of +all other reflection, so inseparably are they connected with every +mode of exercising the understanding. The former denotes the +determinable in general, the second its determination, both in a +transcendental sense, abstraction being made of every difference in +that which is given, and of the mode in which it is determined. +Logicians formerly termed the universal, matter, the specific +difference of this or that part of the universal, form. In a judgement +one may call the given conceptions logical matter (for the judgement), +the relation of these to each other (by means of the copula), the form +of the judgement. In an object, the composite parts thereof +(essentialia) are the matter; the mode in which they are connected +in the object, the form. In respect to things in general, unlimited +reality was regarded as the matter of all possibility, the +limitation thereof (negation) as the form, by which one thing is +distinguished from another according to transcendental conceptions. +The understanding demands that something be given (at least in the +conception), in order to be able to determine it in a certain +manner. Hence, in a conception of the pure understanding, the matter +precedes the form, and for this reason Leibnitz first assumed the +existence of things (monads) and of an internal power of +representation in them, in order to found upon this their external +relation and the community their state (that is, of their +representations). Hence, with him, space and time were possible--the +former through the relation of substances, the latter through the +connection of their determinations with each other, as causes and +effects. And so would it really be, if the pure understanding were +capable of an immediate application to objects, and if space and +time were determinations of things in themselves. But being merely +sensuous intuitions, in which we determine all objects solely as +phenomena, the form of intuition (as a subjective property of +sensibility) must antecede all matter (sensations), consequently space +and time must antecede all phenomena and all data of experience, and +rather make experience itself possible. But the intellectual +philosopher could not endure that the form should precede the things +themselves and determine their possibility; an objection perfectly +correct, if we assume that we intuite things as they are, although +with confused representation. But as sensuous intuition is a +peculiar subjective condition, which is a priori at the foundation +of all perception, and the form of which is primitive, the form must +be given per se, and so far from matter (or the things themselves +which appear) lying at the foundation of experience (as we must +conclude, if we judge by mere conceptions), the very possibility of +itself presupposes, on the contrary, a given formal intuition (space +and time). + + + +REMARK ON THE AMPHIBOLY OF THE CONCEPTIONS OF REFLECTION. + +Let me be allowed to term the position which we assign to a +conception either in the sensibility or in the pure understanding, +the transcendental place. In this manner, the appointment of the +position which must be taken by each conception according to the +difference in its use, and the directions for determining this place +to all conceptions according to rules, would be a transcendental +topic, a doctrine which would thoroughly shield us from the +surreptitious devices of the pure understanding and the delusions +which thence arise, as it would always distinguish to what faculty +of cognition each conception properly belonged. Every conception, +every title, under which many cognitions rank together, may be +called a logical place. Upon this is based the logical topic of +Aristotle, of which teachers and rhetoricians could avail +themselves, in order, under certain titles of thought, to observe what +would best suit the matter they had to treat, and thus enable +themselves to quibble and talk with fluency and an appearance of +profundity. + +Transcendental topic, on the contrary, contains nothing more than +the above-mentioned four titles of all comparison and distinction, +which differ from categories in this respect, that they do not +represent the object according to that which constitutes its +conception (quantity, reality), but set forth merely the comparison +of representations, which precedes our conceptions of things. But this +comparison requires a previous reflection, that is, a determination +of the place to which the representations of the things which are +compared belong, whether, to wit, they are cogitated by the pure +understanding, or given by sensibility. + +Conceptions may be logically compared without the trouble of +inquiring to what faculty their objects belong, whether as noumena, +to the understanding, or as phenomena, to sensibility. If, however, +we wish to employ these conceptions in respect of objects, previous +transcendental reflection is necessary. Without this reflection I +should make a very unsafe use of these conceptions, and construct +pretended synthetical propositions which critical reason cannot +acknowledge and which are based solely upon a transcendental +amphiboly, that is, upon a substitution of an object of pure +understanding for a phenomenon. + +For want of this doctrine of transcendental topic, and +consequently deceived by the amphiboly of the conceptions of +reflection, the celebrated Leibnitz constructed an intellectual system +of the world, or rather, believed himself competent to cognize the +internal nature of things, by comparing all objects merely with the +understanding and the abstract formal conceptions of thought. Our +table of the conceptions of reflection gives us the unexpected +advantage of being able to exhibit the distinctive peculiarities of +his system in all its parts, and at the same time of exposing the +fundamental principle of this peculiar mode of thought, which rested +upon naught but a misconception. He compared all things with each +other merely by means of conceptions, and naturally found no other +differences than those by which the understanding distinguishes its +pure conceptions one from another. The conditions of sensuous +intuition, which contain in themselves their own means of distinction, +he did not look upon as primitive, because sensibility was to him +but a confused mode of representation and not any particular source +of representations. A phenomenon was for him the representation of +the thing in itself, although distinguished from cognition by the +understanding only in respect of the logical form--the former with +its usual want of analysis containing, according to him, a certain +mixture of collateral representations in its conception of a thing, +which it is the duty of the understanding to separate and distinguish. +In one word, Leibnitz intellectualized phenomena, just as Locke, in +his system of noogony (if I may be allowed to make use of such +expressions), sensualized the conceptions of the understanding, that +is to say, declared them to be nothing more than empirical or abstract +conceptions of reflection. Instead of seeking in the understanding +and sensibility two different sources of representations, which, +however, can present us with objective judgements of things only in +conjunction, each of these great men recognized but one of these +faculties, which, in their opinion, applied immediately to things in +themselves, the other having no duty but that of confusing or +arranging the representations of the former. + +Accordingly, the objects of sense were compared by Leibnitz as +things in general merely in the understanding. + +1st. He compares them in regard to their identity or difference +--as judged by the understanding. As, therefore, he considered merely +the conceptions of objects, and not their position in intuition, in +which alone objects can be given, and left quite out of sight the +transcendental locale of these conceptions--whether, that is, their +object ought to be classed among phenomena, or among things in +themselves, it was to be expected that he should extend the +application of the principle of indiscernibles, which is valid +solely of conceptions of things in general, to objects of sense +(mundus phaenomenon), and that he should believe that he had thereby +contributed in no small degree to extend our knowledge of nature. In +truth, if I cognize in all its inner determinations a drop of water +as a thing in itself, I cannot look upon one drop as different from +another, if the conception of the one is completely identical with +that of the other. But if it is a phenomenon in space, it has a +place not merely in the understanding (among conceptions), but also +in sensuous external intuition (in space), and in this case, the physical +locale is a matter of indifference in regard to the internal +determinations of things, and one place, B, may contain a thing +which is perfectly similar and equal to another in a place, A, just +as well as if the two things were in every respect different from each +other. Difference of place without any other conditions, makes the +plurality and distinction of objects as phenomena, not only possible +in itself, but even necessary. Consequently, the above so-called law +is not a law of nature. It is merely an analytical rule for the +comparison of things by means of mere conceptions. + +2nd. The principle: "Realities (as simple affirmations) never +logically contradict each other," is a proposition perfectly true +respecting the relation of conceptions, but, whether as regards +nature, or things in themselves (of which we have not the slightest +conception), is without any the least meaning. For real opposition, +in which A - B is = 0, exists everywhere, an opposition, that is, in +which one reality united with another in the same subject +annihilates the effects of the other--a fact which is constantly +brought before our eyes by the different antagonistic actions and +operations in nature, which, nevertheless, as depending on real +forces, must be called realitates phaenomena. General mechanics can +even present us with the empirical condition of this opposition in +an a priori rule, as it directs its attention to the opposition in +the direction of forces--a condition of which the transcendental +conception of reality can tell us nothing. Although M. Leibnitz did +not announce this proposition with precisely the pomp of a new +principle, he yet employed it for the establishment of new +propositions, and his followers introduced it into their +Leibnitzio-Wolfian system of philosophy. According to this +principle, for example, all evils are but consequences of the +limited nature of created beings, that is, negations, because these +are the only opposite of reality. (In the mere conception of a thing +in general this is really the case, but not in things as phenomena.) +In like manner, the upholders of this system deem it not only +possible, but natural also, to connect and unite all reality in one +being, because they acknowledge no other sort of opposition than +that of contradiction (by which the conception itself of a thing is +annihilated), and find themselves unable to conceive an opposition +of reciprocal destruction, so to speak, in which one real cause +destroys the effect of another, and the conditions of whose +representation we meet with only in sensibility. + +3rd. The Leibnitzian monadology has really no better foundation than +on this philosopher's mode of falsely representing the difference of +the internal and external solely in relation to the understanding. +Substances, in general, must have something inward, which is therefore +free from external relations, consequently from that of composition +also. The simple--that which can be represented by a unit--is +therefore the foundation of that which is internal in things in +themselves. The internal state of substances cannot therefore +consist in place, shape, contact, or motion, determinations which +are all external relations, and we can ascribe to them no other than +that whereby we internally determine our faculty of sense itself, that +is to say, the state of representation. Thus, then, were constructed +the monads, which were to form the elements of the universe, the +active force of which consists in representation, the effects of +this force being thus entirely confined to themselves. + +For the same reason, his view of the possible community of +substances could not represent it but as a predetermined harmony, +and by no means as a physical influence. For inasmuch as everything +is occupied only internally, that is, with its own representations, +the state of the representations of one substance could not stand in +active and living connection with that of another, but some third +cause operating on all without exception was necessary to make the +different states correspond with one another. And this did not +happen by means of assistance applied in each particular case (systema +assistentiae), but through the unity of the idea of a cause occupied +and connected with all substances, in which they necessarily +receive, according to the Leibnitzian school, their existence and +permanence, consequently also reciprocal correspondence, according +to universal laws. + +4th. This philosopher's celebrated doctrine of space and time, in +which he intellectualized these forms of sensibility, originated in +the same delusion of transcendental reflection. If I attempt to +represent by the mere understanding, the external relations of things, +I can do so only by employing the conception of their reciprocal +action, and if I wish to connect one state of the same thing with +another state, I must avail myself of the notion of the order of cause +and effect. And thus Leibnitz regarded space as a certain order in +the community of substances, and time as the dynamical sequence of +their states. That which space and time possess proper to themselves +and independent of things, he ascribed to a necessary confusion in +our conceptions of them, whereby that which is a mere form of dynamical +relations is held to be a self-existent intuition, antecedent even +to things themselves. Thus space and time were the intelligible form +of the connection of things (substances and their states) in +themselves. But things were intelligible substances (substantiae +noumena). At the same time, he made these conceptions valid of +phenomena, because he did not allow to sensibility a peculiar mode +of intuition, but sought all, even the empirical representation of +objects, in the understanding, and left to sense naught but the +despicable task of confusing and disarranging the representations of +the former. + +But even if we could frame any synthetical proposition concerning +things in themselves by means of the pure understanding (which is +impossible), it could not apply to phenomena, which do not represent +things in themselves. In such a case I should be obliged in +transcendental reflection to compare my conceptions only under the +conditions of sensibility, and so space and time would not be +determinations of things in themselves, but of phenomena. What +things may be in themselves, I know not and need not know, because +a thing is never presented to me otherwise than as a phenomenon. + +I must adopt the same mode of procedure with the other conceptions +of reflection. Matter is substantia phaenomenon. That in it which is +internal I seek to discover in all parts of space which it occupies, +and in all the functions and operations it performs, and which are +indeed never anything but phenomena of the external sense. I cannot +therefore find anything that is absolutely, but only what is +comparatively internal, and which itself consists of external +relations. The absolutely internal in matter, and as it should be +according to the pure understanding, is a mere chimera, for matter +is not an object for the pure understanding. But the transcendental +object, which is the foundation of the phenomenon which we call +matter, is a mere nescio quid, the nature of which we could not +understand, even though someone were found able to tell us. For we +can understand nothing that does not bring with it something in +intuition corresponding to the expressions employed. If, by the +complaint of being unable to perceive the internal nature of things, +it is meant that we do not comprehend by the pure understanding what +the things which appear to us may be in themselves, it is a silly +and unreasonable complaint; for those who talk thus really desire that +we should be able to cognize, consequently to intuite, things +without senses, and therefore wish that we possessed a faculty of +cognition perfectly different from the human faculty, not merely in +degree, but even as regards intuition and the mode thereof, so that +thus we should not be men, but belong to a class of beings, the +possibility of whose existence, much less their nature and +constitution, we have no means of cognizing. By observation and +analysis of phenomena we penetrate into the interior of nature, and +no one can say what progress this knowledge may make in time. But those +transcendental questions which pass beyond the limits of nature, we +could never answer, even although all nature were laid open to us, +because we have not the power of observing our own mind with any other +intuition than that of our internal sense. For herein lies the mystery +of the origin and source of our faculty of sensibility. Its +application to an object, and the transcendental ground of this +unity of subjective and objective, lie too deeply concealed for us, +who cognize ourselves only through the internal sense, consequently +as phenomena, to be able to discover in our existence anything but +phenomena, the non-sensuous cause of which we at the same time +earnestly desire to penetrate to. + +The great utility of this critique of conclusions arrived at by +the processes of mere reflection consists in its clear demonstration +of the nullity of all conclusions respecting objects which are +compared with each other in the understanding alone, while it at the +same time confirms what we particularly insisted on, namely, that, +although phenomena are not included as things in themselves among +the objects of the pure understanding, they are nevertheless the +only things by which our cognition can possess objective reality, that +is to say, which give us intuitions to correspond with our +conceptions. + +When we reflect in a purely logical manner, we do nothing more +than compare conceptions in our understanding, to discover whether +both have the same content, whether they are self-contradictory or +not, whether anything is contained in either conception, which of +the two is given, and which is merely a mode of thinking that given. +But if I apply these conceptions to an object in general (in the +transcendental sense), without first determining whether it is an +object of sensuous or intellectual intuition, certain limitations +present themselves, which forbid us to pass beyond the conceptions +and render all empirical use of them impossible. And thus these +limitations prove that the representation of an object as a thing in +general is not only insufficient, but, without sensuous +determination and independently of empirical conditions, +self-contradictory; that we must therefore make abstraction of all +objects, as in logic, or, admitting them, must think them under +conditions of sensuous intuition; that, consequently, the intelligible +requires an altogether peculiar intuition, which we do not possess, +and in the absence of which it is for us nothing; while, on the +other hand phenomena cannot be objects in themselves. For, when I +merely think things in general, the difference in their external +relations cannot constitute a difference in the things themselves; +on the contrary, the former presupposes the latter, and if the +conception of one of two things is not internally different from +that of the other, I am merely thinking the same thing in different +relations. Further, by the addition of one affirmation (reality) to +the other, the positive therein is really augmented, and nothing is +abstracted or withdrawn from it; hence the real in things cannot be +in contradiction with or opposition to itself--and so on. + +The true use of the conceptions of reflection in the employment of +the understanding has, as we have shown, been so misconceived by +Leibnitz, one of the most acute philosophers of either ancient or +modern times, that he has been misled into the construction of a +baseless system of intellectual cognition, which professes to +determine its objects without the intervention of the senses. For this +reason, the exposition of the cause of the amphiboly of these +conceptions, as the origin of these false principles, is of great +utility in determining with certainty the proper limits of the +understanding. + +It is right to say whatever is affirmed or denied of the whole of +a conception can be affirmed or denied of any part of it (dictum de +omni et nullo); but it would be absurd so to alter this logical +proposition as to say whatever is not contained in a general +conception is likewise not contained in the particular conceptions +which rank under it; for the latter are particular conceptions, for +the very reason that their content is greater than that which is +cogitated in the general conception. And yet the whole intellectual +system of Leibnitz is based upon this false principle, and with it +must necessarily fall to the ground, together with all the ambiguous +principles in reference to the employment of the understanding which +have thence originated. + +Leibnitz's principle of the identity of indiscernibles or +indistinguishables is really based on the presupposition that, if in +the conception of a thing a certain distinction is not to be found, +it is also not to be met with in things themselves; that, consequently, +all things are completely identical (numero eadem) which are not +distinguishable from each other (as to quality or quantity) in our +conceptions of them. But, as in the mere conception of anything +abstraction has been made of many necessary conditions of intuition, +that of which abstraction has been made is rashly held to be +non-existent, and nothing is attributed to the thing but what is +contained in its conception. + +The conception of a cubic foot of space, however I may think it, +is in itself completely identical. But two cubic feet in space are +nevertheless distinct from each other from the sole fact of their +being in different places (they are numero diversa); and these +places are conditions of intuition, wherein the object of this +conception is given, and which do not belong to the conception, but +to the faculty of sensibility. In like manner, there is in the conception +of a thing no contradiction when a negative is not connected with an +affirmative; and merely affirmative conceptions cannot, in +conjunction, produce any negation. But in sensuous intuition, +wherein reality (take for example, motion) is given, we find +conditions (opposite directions)--of which abstraction has been made +in the conception of motion in general--which render possible a +contradiction or opposition (not indeed of a logical kind)--and +which from pure positives produce zero = 0. We are therefore not +justified in saying that all reality is in perfect agreement and +harmony, because no contradiction is discoverable among its +conceptions.* According to mere conceptions, that which is internal +is the substratum of all relations or external determinations. When, +therefore, I abstract all conditions of intuition, and confine +myself solely to the conception of a thing in general, I can make +abstraction of all external relations, and there must nevertheless +remain a conception of that which indicates no relation, but merely +internal determinations. Now it seems to follow that in everything +(substance) there is something which is absolutely internal and +which antecedes all external determinations, inasmuch as it renders +them possible; and that therefore this substratum is something which +does not contain any external relations and is consequently simple +(for corporeal things are never anything but relations, at least of +their parts external to each other); and, inasmuch as we know of no +other absolutely internal determinations than those of the internal +sense, this substratum is not only simple, but also, analogously +with our internal sense, determined through representations, that is +to say, all things are properly monads, or simple beings endowed +with the power of representation. Now all this would be perfectly +correct, if the conception of a thing were the only necessary +condition of the presentation of objects of external intuition. It +is, on the contrary, manifest that a permanent phenomenon in space +(impenetrable extension) can contain mere relations, and nothing +that is absolutely internal, and yet be the primary substratum of +all external perception. By mere conceptions I cannot think anything +external, without, at the same time, thinking something internal, +for the reason that conceptions of relations presuppose given +things, and without these are impossible. But, as an intuition there +is something (that is, space, which, with all it contains, consists +of purely formal, or, indeed, real relations) which is not found in +the mere conception of a thing in general, and this presents to us +the substratum which could not be cognized through conceptions alone, +I cannot say: because a thing cannot be represented by mere +conceptions without something absolutely internal, there is also, in +the things themselves which are contained under these conceptions, +and in their intuition nothing external to which something absolutely +internal does not serve as the foundation. For, when we have made +abstraction of all the conditions of intuition, there certainly +remains in the mere conception nothing but the internal in general, +through which alone the external is possible. But this necessity, +which is grounded upon abstraction alone, does not obtain in the +case of things themselves, in so far as they are given in intuition +with such determinations as express mere relations, without having +anything internal as their foundation; for they are not things of a +thing of which we can neither for they are not things in themselves, +but only phenomena. What we cognize in matter is nothing but relations +(what we call its internal determinations are but comparatively +internal). But there are some self-subsistent and permanent, through +which a determined object is given. That I, when abstraction is made +of these relations, have nothing more to think, does not destroy the +conception of a thing as phenomenon, nor the conception of an object +in abstracto, but it does away with the possibility of an object +that is determinable according to mere conceptions, that is, of a +noumenon. It is certainly startling to hear that a thing consists +solely of relations; but this thing is simply a phenomenon, and cannot +be cogitated by means of the mere categories: it does itself consist +in the mere relation of something in general to the senses. In the +same way, we cannot cogitate relations of things in abstracto, if we +commence with conceptions alone, in any other manner than that one +is the cause of determinations in the other; for that is itself the +conception of the understanding or category of relation. But, as in +this case we make abstraction of all intuition, we lose altogether +the mode in which the manifold determines to each of its parts its +place, that is, the form of sensibility (space); and yet this mode +antecedes all empirical causality. + + +[*Footnote: If any one wishes here to have recourse to the usual +subterfuge, and to say, that at least realitates noumena cannot be +in opposition to each other, it will be requisite for him to adduce +an example of this pure and non-sensuous reality, that it may be understood +whether the notion represents something or nothing. But an example +cannot be found except in experience, which never presents to us +anything more than phenomena; and thus the proposition means nothing +more than that the conception which contains only affirmatives does +not contain anything negative--a proposition nobody ever doubted.] + + +If by intelligible objects we understand things which can be thought +by means of the pure categories, without the need of the schemata of +sensibility, such objects are impossible. For the condition of the +objective use of all our conceptions of understanding is the mode of +our sensuous intuition, whereby objects are given; and, if we make +abstraction of the latter, the former can have no relation to an +object. And even if we should suppose a different kind of intuition +from our own, still our functions of thought would have no use or +signification in respect thereof. But if we understand by the term, +objects of a non-sensuous intuition, in respect of which our +categories are not valid, and of which we can accordingly have no +knowledge (neither intuition nor conception), in this merely +negative sense noumena must be admitted. For this is no more than +saying that our mode of intuition is not applicable to all things, +but only to objects of our senses, that consequently its objective +validity is limited, and that room is therefore left for another +kind of intuition, and thus also for things that may be objects of +it. But in this sense the conception of a noumenon is problematical, +that is to say, it is the notion of that it that it is possible, nor +that it is impossible, inasmuch as we do not know of any mode of +intuition besides the sensuous, or of any other sort of conceptions +than the categories--a mode of intuition and a kind of conception +neither of which is applicable to a non-sensuous object. We are on +this account incompetent to extend the sphere of our objects of +thought beyond the conditions of our sensibility, and to assume the +existence of objects of pure thought, that is, of noumena, inasmuch +as these have no true positive signification. For it must be confessed +of the categories that they are not of themselves sufficient for the +cognition of things in themselves and, without the data of +sensibility, are mere subjective forms of the unity of the +understanding. Thought is certainly not a product of the senses, and +in so far is not limited by them, but it does not therefore follow +that it may be employed purely and without the intervention of +sensibility, for it would then be without reference to an object. +And we cannot call a noumenon an object of pure thought; for the +representation thereof is but the problematical conception of an +object for a perfectly different intuition and a perfectly different +understanding from ours, both of which are consequently themselves +problematical. The conception of a noumenon is therefore not the +conception of an object, but merely a problematical conception +inseparably connected with the limitation of our sensibility. That +is to say, this conception contains the answer to the question: "Are +there objects quite unconnected with, and independent of, our +intuition?"--a question to which only an indeterminate answer can be +given. That answer is: "Inasmuch as sensuous intuition does not +apply to all things without distinction, there remains room for +other and different objects." The existence of these problematical +objects is therefore not absolutely denied, in the absence of a +determinate conception of them, but, as no category is valid in +respect of them, neither must they be admitted as objects for our +understanding. + +Understanding accordingly limits sensibility, without at the same +time enlarging its own field. While, moreover, it forbids +sensibility to apply its forms and modes to things in themselves and +restricts it to the sphere of phenomena, it cogitates an object in +itself, only, however, as a transcendental object, which is the +cause of a phenomenon (consequently not itself a phenomenon), and +which cannot be thought either as a quantity or as reality, or as +substance (because these conceptions always require sensuous forms +in which to determine an object)--an object, therefore, of which we +are quite unable to say whether it can be met with in ourselves or +out of us, whether it would be annihilated together with sensibility, +or, if this were taken away, would continue to exist. If we wish to +call this object a noumenon, because the representation of it is +non-sensuous, we are at liberty to do so. But as we can apply to it +none of the conceptions of our understanding, the representation is +for us quite void, and is available only for the indication of the +limits of our sensuous intuition, thereby leaving at the same time +an empty space, which we are competent to fill by the aid neither of +possible experience, nor of the pure understanding. + +The critique of the pure understanding, accordingly, does not permit +us to create for ourselves a new field of objects beyond those which +are presented to us as phenomena, and to stray into intelligible +worlds; nay, it does not even allow us to endeavour to form so much +as a conception of them. The specious error which leads to this--and +which is a perfectly excusable one--lies in the fact that the +employment of the understanding, contrary to its proper purpose and +destination, is made transcendental, and objects, that is, possible +intuitions, are made to regulate themselves according to +conceptions, instead of the conceptions arranging themselves according +to the intuitions, on which alone their own objective validity +rests. Now the reason of this again is that apperception, and with +it thought, antecedes all possible determinate arrangement of +representations. Accordingly we think something in general and +determine it on the one hand sensuously, but, on the other, +distinguish the general and in abstracto represented object from +this particular mode of intuiting it. In this case there remains a +mode of determining the object by mere thought, which is really but +a logical form without content, which, however, seems to us to be a +mode of the existence of the object in itself (noumenon), without +regard to intuition which is limited to our senses. + +Before ending this transcendental analytic, we must make an +addition, which, although in itself of no particular importance, seems +to be necessary to the completeness of the system. The highest +conception, with which a transcendental philosophy commonly begins, +is the division into possible and impossible. But as all division +presupposes a divided conception, a still higher one must exist, and +this is the conception of an object in general--problematically +understood and without its being decided whether it is something or +nothing. As the categories are the only conceptions which apply to +objects in general, the distinguishing of an object, whether it is +something or nothing, must proceed according to the order and +direction of the categories. + +1. To the categories of quantity, that is, the conceptions of all, +many, and one, the conception which annihilates all, that is, the +conception of none, is opposed. And thus the object of a conception, +to which no intuition can be found to correspond, is = nothing. That +is, it is a conception without an object (ens rationis), like noumena, +which cannot be considered possible in the sphere of reality, though +they must not therefore be held to be impossible--or like certain +new fundamental forces in matter, the existence of which is +cogitable without contradiction, though, as examples from experience +are not forthcoming, they must not be regarded as possible. + +2. Reality is something; negation is nothing, that is, a +conception of the absence of an object, as cold, a shadow (nihil +privativum). + +3. The mere form of intuition, without substance, is in itself no +object, but the merely formal condition of an object (as +phenomenon), as pure space and pure time. These are certainly +something, as forms of intuition, but are not themselves objects which +are intuited (ens imaginarium). + +4. The object of a conception which is self-contradictory, is +nothing, because the conception is nothing--is impossible, as a figure +composed of two straight lines (nihil negativum). + +The table of this division of the conception of nothing (the +corresponding division of the conception of something does not require +special description) must therefore be arranged as follows: + + + NOTHING + AS + + 1 + As Empty Conception + without object, + ens rationis + 2 3 + Empty object of Empty intuition + a conception, without object, + nihil privativum ens imaginarium + 4 + Empty object + without conception, + nihil negativum + + +We see that the ens rationis is distinguished from the nihil +negativum or pure nothing by the consideration that the former must +not be reckoned among possibilities, because it is a mere fiction- +though not self-contradictory, while the latter is completely +opposed to all possibility, inasmuch as the conception annihilates +itself. Both, however, are empty conceptions. On the other hand, +the nihil privativum and ens imaginarium are empty data for +conceptions. If light be not given to the senses, we cannot +represent to ourselves darkness, and if extended objects are not +perceived, we cannot represent space. Neither the negation, nor the +mere form of intuition can, without something real, be an object. + + + + +TRANSCENDENTAL LOGIC. SECOND DIVISION. + +TRANSCENDENTAL DIALECTIC. INTRODUCTION. + +I. Of Transcendental Illusory Appearance. + +We termed dialectic in general a logic of appearance. This does +not signify a doctrine of probability; for probability is truth, +only cognized upon insufficient grounds, and though the information +it gives us is imperfect, it is not therefore deceitful. Hence it must +not be separated from the analytical part of logic. Still less must +phenomenon and appearance be held to be identical. For truth or +illusory appearance does not reside in the object, in so far as it +is intuited, but in the judgement upon the object, in so far as it +is thought. It is, therefore, quite correct to say that the senses +do not err, not because they always judge correctly, but because +they do not judge at all. Hence truth and error, consequently also, +illusory appearance as the cause of error, are only to be found in +a judgement, that is, in the relation of an object to our understanding. +In a cognition which completely harmonizes with the laws of the +understanding, no error can exist. In a representation of the +senses--as not containing any judgement--there is also no error. But +no power of nature can of itself deviate from its own laws. Hence +neither the understanding per se (without the influence of another +cause), nor the senses per se, would fall into error; the former could +not, because, if it acts only according to its own laws, the effect +(the judgement) must necessarily accord with these laws. But in +accordance with the laws of the understanding consists the formal +element in all truth. In the senses there is no judgement--neither +a true nor a false one. But, as we have no source of cognition besides +these two, it follows that error is caused solely by the unobserved +influence of the sensibility upon the understanding. And thus it +happens that the subjective grounds of a judgement and are +confounded with the objective, and cause them to deviate from their +proper determination,* just as a body in motion would always of itself +proceed in a straight line, but if another impetus gives to it a +different direction, it will then start off into a curvilinear line +of motion. To distinguish the peculiar action of the understanding +from the power which mingles with it, it is necessary to consider an +erroneous judgement as the diagonal between two forces, that determine +the judgement in two different directions, which, as it were, form +an angle, and to resolve this composite operation into the simple ones +of the understanding and the sensibility. In pure a priori +judgements this must be done by means of transcendental reflection, +whereby, as has been already shown, each representation has its +place appointed in the corresponding faculty of cognition, and +consequently the influence of the one faculty upon the other is made +apparent. + +[*Footnote: Sensibility, subjected to the understanding, as the object +upon which the understanding employs its functions, is the source of +real cognitions. But, in so far as it exercises an influence upon the +action of the understanding and determines it to judgement, +sensibility is itself the cause of error.] + +It is not at present our business to treat of empirical illusory +appearance (for example, optical illusion), which occurs in the +empirical application of otherwise correct rules of the understanding, +and in which the judgement is misled by the influence of +imagination. Our purpose is to speak of transcendental illusory +appearance, which influences principles--that are not even applied +to experience, for in this case we should possess a sure test of their +correctness--but which leads us, in disregard of all the warnings of +criticism, completely beyond the empirical employment of the +categories and deludes us with the chimera of an extension of the +sphere of the pure understanding. We shall term those principles the +application of which is confined entirely within the limits of +possible experience, immanent; those, on the other hand, which +transgress these limits, we shall call transcendent principles. But +by these latter I do not understand principles of the transcendental +use or misuse of the categories, which is in reality a mere fault of +the judgement when not under due restraint from criticism, and +therefore not paying sufficient attention to the limits of the +sphere in which the pure understanding is allowed to exercise its +functions; but real principles which exhort us to break down all those +barriers, and to lay claim to a perfectly new field of cognition, +which recognizes no line of demarcation. Thus transcendental and +transcendent are not identical terms. The principles of the pure +understanding, which we have already propounded, ought to be of +empirical and not of transcendental use, that is, they are not +applicable to any object beyond the sphere of experience. A +principle which removes these limits, nay, which authorizes us to +overstep them, is called transcendent. If our criticism can succeed +in exposing the illusion in these pretended principles, those which +are limited in their employment to the sphere of experience may be +called, in opposition to the others, immanent principles of the pure +understanding. + +Logical illusion, which consists merely in the imitation of the form +of reason (the illusion in sophistical syllogisms), arises entirely +from a want of due attention to logical rules. So soon as the +attention is awakened to the case before us, this illusion totally +disappears. Transcendental illusion, on the contrary, does not cease +to exist, even after it has been exposed, and its nothingness +clearly perceived by means of transcendental criticism. Take, for +example, the illusion in the proposition: "The world must have a +beginning in time." The cause of this is as follows. In our reason, +subjectively considered as a faculty of human cognition, there exist +fundamental rules and maxims of its exercise, which have completely +the appearance of objective principles. Now from this cause it happens +that the subjective necessity of a certain connection of our +conceptions, is regarded as an objective necessity of the +determination of things in themselves. This illusion it is +impossible to avoid, just as we cannot avoid perceiving that the sea +appears to be higher at a distance than it is near the shore, +because we see the former by means of higher rays than the latter, +or, which is a still stronger case, as even the astronomer cannot +prevent himself from seeing the moon larger at its rising than some +time afterwards, although he is not deceived by this illusion. + +Transcendental dialectic will therefore content itself with exposing +the illusory appearance in transcendental judgements, and guarding +us against it; but to make it, as in the case of logical illusion, +entirely disappear and cease to be illusion is utterly beyond its +power. For we have here to do with a natural and unavoidable illusion, +which rests upon subjective principles and imposes these upon us as +objective, while logical dialectic, in the detection of sophisms, +has to do merely with an error in the logical consequence of the +propositions, or with an artificially constructed illusion, in +imitation of the natural error. There is, therefore, a natural and +unavoidable dialectic of pure reason--not that in which the bungler, +from want of the requisite knowledge, involves himself, nor that which +the sophist devises for the purpose of misleading, but that which is +an inseparable adjunct of human reason, and which, even after its +illusions have been exposed, does not cease to deceive, and +continually to lead reason into momentary errors, which it becomes +necessary continually to remove. + + + +II. Of Pure Reason as the Seat of Transcendental Illusory Appearance. + +A. OF REASON IN GENERAL. + +All our knowledge begins with sense, proceeds thence to +understanding, and ends with reason, beyond which nothing higher can +be discovered in the human mind for elaborating the matter of +intuition and subjecting it to the highest unity of thought. At this +stage of our inquiry it is my duty to give an explanation of this, +the highest faculty of cognition, and I confess I find myself here +in some difficulty. Of reason, as of the understanding, there is a +merely formal, that is, logical use, in which it makes abstraction +of all content of cognition; but there is also a real use, inasmuch +as it contains in itself the source of certain conceptions and principles, +which it does not borrow either from the senses or the +understanding. The former faculty has been long defined by logicians +as the faculty of mediate conclusion in contradistinction to immediate +conclusions (consequentiae immediatae); but the nature of the +latter, which itself generates conceptions, is not to be understood +from this definition. Now as a division of reason into a logical and +a transcendental faculty presents itself here, it becomes necessary +to seek for a higher conception of this source of cognition which shall +comprehend both conceptions. In this we may expect, according to the +analogy of the conceptions of the understanding, that the logical +conception will give us the key to the transcendental, and that the +table of the functions of the former will present us with the clue +to the conceptions of reason. + +In the former part of our transcendental logic, we defined the +understanding to be the faculty of rules; reason may be +distinguished from understanding as the faculty of principles. + +The term principle is ambiguous, and commonly signifies merely a +cognition that may be employed as a principle, although it is not in +itself, and as regards its proper origin, entitled to the distinction. +Every general proposition, even if derived from experience by the +process of induction, may serve as the major in a syllogism; but it +is not for that reason a principle. Mathematical axioms (for example, +there can be only one straight line between two points) are general +a priori cognitions, and are therefore rightly denominated principles, +relatively to the cases which can be subsumed under them. But I cannot +for this reason say that I cognize this property of a straight line +from principles--I cognize it only in pure intuition. + +Cognition from principles, then, is that cognition in which I +cognize the particular in the general by means of conceptions. Thus +every syllogism is a form of the deduction of a cognition from a +principle. For the major always gives a conception, through which +everything that is subsumed under the condition thereof is cognized +according to a principle. Now as every general cognition may serve +as the major in a syllogism, and the understanding presents us with +such general a priori propositions, they may be termed principles, +in respect of their possible use. + +But if we consider these principles of the pure understanding in +relation to their origin, we shall find them to be anything rather +than cognitions from conceptions. For they would not even be +possible a priori, if we could not rely on the assistance of pure +intuition (in mathematics), or on that of the conditions of a possible +experience. That everything that happens has a cause, cannot be +concluded from the general conception of that which happens; on the +contrary the principle of causality instructs us as to the mode of +obtaining from that which happens a determinate empirical conception. + +Synthetical cognitions from conceptions the understanding cannot +supply, and they alone are entitled to be called principles. At the +same time, all general propositions may be termed comparative +principles. + +It has been a long-cherished wish--that (who knows how late), may +one day, be happily accomplished--that the principles of the endless +variety of civil laws should be investigated and exposed; for in +this way alone can we find the secret of simplifying legislation. +But in this case, laws are nothing more than limitations of our +freedom upon conditions under which it subsists in perfect harmony +with itself; they consequently have for their object that which is +completely our own work, and of which we ourselves may be the cause +by means of these conceptions. But how objects as things in themselves- +how the nature of things is subordinated to principles and is to be +determined, according to conceptions, is a question which it seems +well nigh impossible to answer. Be this, however, as it may--for on +this point our investigation is yet to be made--it is at least +manifest from what we have said that cognition from principles is +something very different from cognition by means of the understanding, +which may indeed precede other cognitions in the form of a +principle, but in itself--in so far as it is synthetical--is neither +based upon mere thought, nor contains a general proposition drawn from +conceptions alone. + +The understanding may be a faculty for the production of unity of +phenomena by virtue of rules; the reason is a faculty for the +production of unity of rules (of the understanding) under +principles. Reason, therefore, never applies directly to experience, +or to any sensuous object; its object is, on the contrary, the +understanding, to the manifold cognition of which it gives a unity +a priori by means of conceptions--a unity which may be called rational +unity, and which is of a nature very different from that of the +unity produced by the understanding. + +The above is the general conception of the faculty of reason, in +so far as it has been possible to make it comprehensible in the +absence of examples. These will be given in the sequel. + + + +B. OF THE LOGICAL USE OF REASON. + +A distinction is commonly made between that which is immediately +cognized and that which is inferred or concluded. That in a figure +which is bounded by three straight lines there are three angles, is +an immediate cognition; but that these angles are together equal to +two right angles, is an inference or conclusion. Now, as we are constantly +employing this mode of thought and have thus become quite accustomed +to it, we no longer remark the above distinction, and, as in the +case of the so-called deceptions of sense, consider as immediately +perceived, what has really been inferred. In every reasoning or +syllogism, there is a fundamental proposition, afterwards a second +drawn from it, and finally the conclusion, which connects the truth +in the first with the truth in the second--and that infallibly. If +the judgement concluded is so contained in the first proposition that +it can be deduced from it without the meditation of a third notion, +the conclusion is called immediate (consequentia immediata); I prefer +the term conclusion of the understanding. But if, in addition to the +fundamental cognition, a second judgement is necessary for the +production of the conclusion, it is called a conclusion of the reason. +In the proposition: All men are mortal, are contained the +propositions: Some men are mortal, Nothing that is not mortal is a +man, and these are therefore immediate conclusions from the first. +On the other hand, the proposition: all the learned are mortal, is +not contained in the main proposition (for the conception of a learned +man does not occur in it), and it can be deduced from the main proposition +only by means of a mediating judgement. + +In every syllogism I first cogitate a rule (the major) by means of +the understanding. In the next place I subsume a cognition under the +condition of the rule (and this is the minor) by means of the +judgement. And finally I determine my cognition by means of the +predicate of the rule (this is the conclusio), consequently, I +determine it a priori by means of the reason. The relations, +therefore, which the major proposition, as the rule, represents +between a cognition and its condition, constitute the different +kinds of syllogisms. These are just threefold--analogously with all +judgements, in so far as they differ in the mode of expressing the +relation of a cognition in the understanding--namely, categorical, +hypothetical, and disjunctive. + +When as often happens, the conclusion is a judgement which may +follow from other given judgements, through which a perfectly +different object is cogitated, I endeavour to discover in the +understanding whether the assertion in this conclusion does not +stand under certain conditions according to a general rule. If I +find such a condition, and if the object mentioned in the conclusion +can be subsumed under the given condition, then this conclusion +follows from a rule which is also valid for other objects of +cognition. From this we see that reason endeavours to subject the +great variety of the cognitions of the understanding to the smallest +possible number of principles (general conditions), and thus to +produce in it the highest unity. + + + +C. OF THE PURE USE OF REASON. + +Can we isolate reason, and, if so, is it in this case a peculiar +source of conceptions and judgements which spring from it alone, and +through which it can be applied to objects; or is it merely a +subordinate faculty, whose duty it is to give a certain form to +given cognitions--a form which is called logical, and through which +the cognitions of the understanding are subordinated to each other, +and lower rules to higher (those, to wit, whose condition comprises +in its sphere the condition of the others), in so far as this can be +done by comparison? This is the question which we have at present to +answer. Manifold variety of rules and unity of principles is a +requirement of reason, for the purpose of bringing the understanding +into complete accordance with itself, just as understanding subjects +the manifold content of intuition to conceptions, and thereby +introduces connection into it. But this principle prescribes no law +to objects, and does not contain any ground of the possibility of +cognizing or of determining them as such, but is merely a subjective +law for the proper arrangement of the content of the understanding. +The purpose of this law is, by a comparison of the conceptions of +the understanding, to reduce them to the smallest possible number, +although, at the same time, it does not justify us in demanding from +objects themselves such a uniformity as might contribute to the +convenience and the enlargement of the sphere of the understanding, +or in expecting that it will itself thus receive from them objective +validity. In one word, the question is: "does reason in itself, that +is, does pure reason contain a priori synthetical principles and +rules, and what are those principles?" + +The formal and logical procedure of reason in syllogisms gives us +sufficient information in regard to the ground on which the +transcendental principle of reason in its pure synthetical cognition +will rest. + +1. Reason, as observed in the syllogistic process, is not applicable +to intuitions, for the purpose of subjecting them to rules--for this +is the province of the understanding with its categories--but to +conceptions and judgements. If pure reason does apply to objects and +the intuition of them, it does so not immediately, but mediately- +through the understanding and its judgements, which have a direct +relation to the senses and their intuition, for the purpose of +determining their objects. The unity of reason is therefore not the +unity of a possible experience, but is essentially different from this +unity, which is that of the understanding. That everything which +happens has a cause, is not a principle cognized and prescribed by +reason. This principle makes the unity of experience possible and +borrows nothing from reason, which, without a reference to possible +experience, could never have produced by means of mere conceptions +any such synthetical unity. + +2. Reason, in its logical use, endeavours to discover the general +condition of its judgement (the conclusion), and a syllogism is itself +nothing but a judgement by means of the subsumption of its condition +under a general rule (the major). Now as this rule may itself be +subjected to the same process of reason, and thus the condition of +the condition be sought (by means of a prosyllogism) as long as the +process can be continued, it is very manifest that the peculiar +principle of reason in its logical use is to find for the +conditioned cognition of the understanding the unconditioned whereby +the unity of the former is completed. + +But this logical maxim cannot be a principle of pure reason, +unless we admit that, if the conditioned is given, the whole series +of conditions subordinated to one another--a series which is consequently +itself unconditioned--is also given, that is, contained in the +object and its connection. + +But this principle of pure reason is evidently synthetical; for, +analytically, the conditioned certainly relates to some condition, +but not to the unconditioned. From this principle also there must +originate different synthetical propositions, of which the pure +understanding is perfectly ignorant, for it has to do only with +objects of a possible experience, the cognition and synthesis of which +is always conditioned. The unconditioned, if it does really exist, +must be especially considered in regard to the determinations which +distinguish it from whatever is conditioned, and will thus afford us +material for many a priori synthetical propositions. + +The principles resulting from this highest principle of pure +reason will, however, be transcendent in relation to phenomena, that +is to say, it will be impossible to make any adequate empirical use +of this principle. It is therefore completely different from all +principles of the understanding, the use made of which is entirely +immanent, their object and purpose being merely the possibility of +experience. Now our duty in the transcendental dialectic is as +follows. To discover whether the principle that the series of +conditions (in the synthesis of phenomena, or of thought in general) +extends to the unconditioned is objectively true, or not; what +consequences result therefrom affecting the empirical use of the +understanding, or rather whether there exists any such objectively +valid proposition of reason, and whether it is not, on the contrary, +a merely logical precept which directs us to ascend perpetually to +still higher conditions, to approach completeness in the series of +them, and thus to introduce into our cognition the highest possible +unity of reason. We must ascertain, I say, whether this requirement +of reason has not been regarded, by a misunderstanding, as a transcendental +principle of pure reason, which postulates a thorough completeness +in the series of conditions in objects themselves. We must show, +moreover, the misconceptions and illusions that intrude into +syllogisms, the major proposition of which pure reason has supplied--a +proposition which has perhaps more of the character of a petitio +than of a postulatum--and that proceed from experience upwards to +its conditions. The solution of these problems is our task in +transcendental dialectic, which we are about to expose even at its +source, that lies deep in human reason. We shall divide it into two +parts, the first of which will treat of the transcendent conceptions +of pure reason, the second of transcendent and dialectical syllogisms. + + + + +BOOK I. + +OF THE CONCEPTIONS OF PURE REASON. + +The conceptions of pure reason--we do not here speak of the +possibility of them--are not obtained by reflection, but by +inference or conclusion. The conceptions of understanding are also +cogitated a priori antecedently to experience, and render it possible; +but they contain nothing but the unity of reflection upon phenomena, +in so far as these must necessarily belong to a possible empirical +consciousness. Through them alone are cognition and the +determination of an object possible. It is from them, accordingly, +that we receive material for reasoning, and antecedently to them we +possess no a priori conceptions of objects from which they might be +deduced, On the other hand, the sole basis of their objective +reality consists in the necessity imposed on them, as containing the +intellectual form of all experience, of restricting their +application and influence to the sphere of experience. + +But the term, conception of reason, or rational conception, itself +indicates that it does not confine itself within the limits of +experience, because its object-matter is a cognition, of which every +empirical cognition is but a part--nay, the whole of possible +experience may be itself but a part of it--a cognition to which no +actual experience ever fully attains, although it does always +pertain to it. The aim of rational conceptions is the comprehension, +as that of the conceptions of understanding is the understanding of +perceptions. If they contain the unconditioned, they relate to that +to which all experience is subordinate, but which is never itself an +object of experience--that towards which reason tends in all its +conclusions from experience, and by the standard of which it estimates +the degree of their empirical use, but which is never itself an +element in an empirical synthesis. If, notwithstanding, such +conceptions possess objective validity, they may be called conceptus +ratiocinati (conceptions legitimately concluded); in cases where +they do not, they have been admitted on account of having the +appearance of being correctly concluded, and may be called conceptus +ratiocinantes (sophistical conceptions). But as this can only be +sufficiently demonstrated in that part of our treatise which relates +to the dialectical conclusions of reason, we shall omit any +consideration of it in this place. As we called the pure conceptions +of the understanding categories, we shall also distinguish those of +pure reason by a new name and call them transcendental ideas. These +terms, however, we must in the first place explain and justify. + + + +SECTION I--Of Ideas in General. + +Despite the great wealth of words which European languages +possess, the thinker finds himself often at a loss for an expression +exactly suited to his conception, for want of which he is unable to +make himself intelligible either to others or to himself. To coin +new words is a pretension to legislation in language which is seldom +successful; and, before recourse is taken to so desperate an +expedient, it is advisable to examine the dead and learned +languages, with the hope and the probability that we may there meet +with some adequate expression of the notion we have in our minds. In +this case, even if the original meaning of the word has become +somewhat uncertain, from carelessness or want of caution on the part +of the authors of it, it is always better to adhere to and confirm +its proper meaning--even although it may be doubtful whether it was +formerly used in exactly this sense--than to make our labour vain by +want of sufficient care to render ourselves intelligible. + +For this reason, when it happens that there exists only a single +word to express a certain conception, and this word, in its usual +acceptation, is thoroughly adequate to the conception, the accurate +distinction of which from related conceptions is of great +importance, we ought not to employ the expression improvidently, or, +for the sake of variety and elegance of style, use it as a synonym +for other cognate words. It is our duty, on the contrary, carefully +to preserve its peculiar signification, as otherwise it easily happens +that when the attention of the reader is no longer particularly +attracted to the expression, and it is lost amid the multitude of +other words of very different import, the thought which it conveyed, +and which it alone conveyed, is lost with it. + +Plato employed the expression idea in a way that plainly showed he +meant by it something which is never derived from the senses, but +which far transcends even the conceptions of the understanding (with +which Aristotle occupied himself), inasmuch as in experience nothing +perfectly corresponding to them could be found. Ideas are, according +to him, archetypes of things themselves, and not merely keys to +possible experiences, like the categories. In his view they flow +from the highest reason, by which they have been imparted to human +reason, which, however, exists no longer in its original state, but +is obliged with great labour to recall by reminiscence--which is called +philosophy--the old but now sadly obscured ideas. I will not here +enter upon any literary investigation of the sense which this +sublime philosopher attached to this expression. I shall content +myself with remarking that it is nothing unusual, in common +conversation as well as in written works, by comparing the thoughts +which an author has delivered upon a subject, to understand him better +than he understood himself inasmuch as he may not have sufficiently +determined his conception, and thus have sometimes spoken, nay even +thought, in opposition to his own opinions. + +Plato perceived very clearly that our faculty of cognition has the +feeling of a much higher vocation than that of merely spelling out +phenomena according to synthetical unity, for the purpose of being +able to read them as experience, and that our reason naturally +raises itself to cognitions far too elevated to admit of the +possibility of an object given by experience corresponding to them- +cognitions which are nevertheless real, and are not mere phantoms of +the brain. + +This philosopher found his ideas especially in all that is +practical,* that is, which rests upon freedom, which in its turn ranks +under cognitions that are the peculiar product of reason. He who would +derive from experience the conceptions of virtue, who would make (as +many have really done) that, which at best can but serve as an +imperfectly illustrative example, a model for or the formation of a +perfectly adequate idea on the subject, would in fact transform virtue +into a nonentity changeable according to time and circumstance and +utterly incapable of being employed as a rule. On the contrary, +every one is conscious that, when any one is held up to him as a model +of virtue, he compares this so-called model with the true original +which he possesses in his own mind and values him according to this +standard. But this standard is the idea of virtue, in relation to +which all possible objects of experience are indeed serviceable as +examples--proofs of the practicability in a certain degree of that +which the conception of virtue demands--but certainly not as +archetypes. That the actions of man will never be in perfect +accordance with all the requirements of the pure ideas of reason, does +not prove the thought to be chimerical. For only through this idea +are all judgements as to moral merit or demerit possible; it +consequently lies at the foundation of every approach to moral +perfection, however far removed from it the obstacles in human nature- +indeterminable as to degree--may keep us. + +[*Footnote: He certainly extended the application of his conception +to speculative cognitions also, provided they were given pure and +completely a priori, nay, even to mathematics, although this science +cannot possess an object otherwhere than in Possible experience. I +cannot follow him in this, and as little can I follow him in his +mystical deduction of these ideas, or in his hypostatization of +them; although, in truth, the elevated and exaggerated language +which he employed in describing them is quite capable of an +interpretation more subdued and more in accordance with fact and the +nature of things.] + +The Platonic Republic has become proverbial as an example--and a +striking one--of imaginary perfection, such as can exist only in the +brain of the idle thinker; and Brucker ridicules the philosopher for +maintaining that a prince can never govern well, unless he is +participant in the ideas. But we should do better to follow up this +thought and, where this admirable thinker leaves us without +assistance, employ new efforts to place it in clearer light, rather +than carelessly fling it aside as useless, under the very miserable +and pernicious pretext of impracticability. A constitution of the +greatest possible human freedom according to laws, by which the +liberty of every individual can consist with the liberty of every +other (not of the greatest possible happiness, for this follows +necessarily from the former), is, to say the least, a necessary +idea, which must be placed at the foundation not only of the first +plan of the constitution of a state, but of all its laws. And, in +this, it not necessary at the outset to take account of the +obstacles which lie in our way--obstacles which perhaps do not +necessarily arise from the character of human nature, but rather +from the previous neglect of true ideas in legislation. For there is +nothing more pernicious and more unworthy of a philosopher, than the +vulgar appeal to a so-called adverse experience, which indeed would +not have existed, if those institutions had been established at the +proper time and in accordance with ideas; while, instead of this, +conceptions, crude for the very reason that they have been drawn +from experience, have marred and frustrated all our better views and +intentions. The more legislation and government are in harmony with +this idea, the more rare do punishments become and thus it is quite +reasonable to maintain, as Plato did, that in a perfect state no +punishments at all would be necessary. Now although a perfect state +may never exist, the idea is not on that account the less just, +which holds up this maximum as the archetype or standard of a +constitution, in order to bring legislative government always nearer +and nearer to the greatest possible perfection. For at what precise +degree human nature must stop in its progress, and how wide must be +the chasm which must necessarily exist between the idea and its +realization, are problems which no one can or ought to determine- +and for this reason, that it is the destination of freedom to overstep +all assigned limits between itself and the idea. + +But not only in that wherein human reason is a real causal agent and +where ideas are operative causes (of actions and their objects), +that is to say, in the region of ethics, but also in regard to +nature herself, Plato saw clear proofs of an origin from ideas. A +plant, and animal, the regular order of nature--probably also the +disposition of the whole universe--give manifest evidence that they +are possible only by means of and according to ideas; that, indeed, +no one creature, under the individual conditions of its existence, +perfectly harmonizes with the idea of the most perfect of its kind- +just as little as man with the idea of humanity, which nevertheless +he bears in his soul as the archetypal standard of his actions; that, +notwithstanding, these ideas are in the highest sense individually, +unchangeably, and completely determined, and are the original causes +of things; and that the totality of connected objects in the +universe is alone fully adequate to that idea. Setting aside the +exaggerations of expression in the writings of this philosopher, the +mental power exhibited in this ascent from the ectypal mode of +regarding the physical world to the architectonic connection thereof +according to ends, that is, ideas, is an effort which deserves +imitation and claims respect. But as regards the principles of ethics, +of legislation, and of religion, spheres in which ideas alone render +experience possible, although they never attain to full expression +therein, he has vindicated for himself a position of peculiar merit, +which is not appreciated only because it is judged by the very +empirical rules, the validity of which as principles is destroyed by +ideas. For as regards nature, experience presents us with rules and +is the source of truth, but in relation to ethical laws experience +is the parent of illusion, and it is in the highest degree reprehensible +to limit or to deduce the laws which dictate what I ought to do, from +what is done. + +We must, however, omit the consideration of these important +subjects, the development of which is in reality the peculiar duty +and dignity of philosophy, and confine ourselves for the present to +the more humble but not less useful task of preparing a firm foundation +for those majestic edifices of moral science. For this foundation +has been hitherto insecure from the many subterranean passages which +reason in its confident but vain search for treasures has made in +all directions. Our present duty is to make ourselves perfectly +acquainted with the transcendental use made of pure reason, its +principles and ideas, that we may be able properly to determine and +value its influence and real worth. But before bringing these +introductory remarks to a close, I beg those who really have +philosophy at heart--and their number is but small--if they shall find +themselves convinced by the considerations following as well as by +those above, to exert themselves to preserve to the expression idea +its original signification, and to take care that it be not lost among +those other expressions by which all sorts of representations are +loosely designated--that the interests of science may not thereby +suffer. We are in no want of words to denominate adequately every mode +of representation, without the necessity of encroaching upon terms +which are proper to others. The following is a graduated list of them. +The genus is representation in general (representatio). Under it +stands representation with consciousness (perceptio). A perception +which relates solely to the subject as a modification of its state, +is a sensation (sensatio), an objective perception is a cognition +(cognitio). A cognition is either an intuition or a conception +(intuitus vel conceptus). The former has an immediate relation to +the object and is singular and individual; the latter has but a +mediate relation, by means of a characteristic mark which may be +common to several things. A conception is either empirical or pure. +A pure conception, in so far as it has its origin in the understanding +alone, and is not the conception of a pure sensuous image, is called +notio. A conception formed from notions, which transcends the +possibility of experience, is an idea, or a conception of reason. To +one who has accustomed himself to these distinctions, it must be quite +intolerable to hear the representation of the colour red called an +idea. It ought not even to be called a notion or conception of +understanding. + + + +SECTION II. Of Transcendental Ideas. + +Transcendental analytic showed us how the mere logical form of our +cognition can contain the origin of pure conceptions a priori, +conceptions which represent objects antecedently to all experience, +or rather, indicate the synthetical unity which alone renders possible +an empirical cognition of objects. The form of judgements--converted +into a conception of the synthesis of intuitions--produced the categories +which direct the employment of the understanding in experience. This +consideration warrants us to expect that the form of syllogisms, +when applied to synthetical unity of intuitions, following the rule +of the categories, will contain the origin of particular a priori +conceptions, which we may call pure conceptions of reason or +transcendental ideas, and which will determine the use of the +understanding in the totality of experience according to principles. + +The function of reason in arguments consists in the universality +of a cognition according to conceptions, and the syllogism itself is +a judgement which is determined a priori in the whole extent of its +condition. The proposition: "Caius is mortal," is one which may be +obtained from experience by the aid of the understanding alone; but +my wish is to find a conception which contains the condition under +which the predicate of this judgement is given--in this case, the +conception of man--and after subsuming under this condition, taken +in its whole extent (all men are mortal), I determine according to +it the cognition of the object thought, and say: "Caius is mortal." + +Hence, in the conclusion of a syllogism we restrict a predicate to +a certain object, after having thought it in the major in its whole +extent under a certain condition. This complete quantity of the extent +in relation to such a condition is called universality +(universalitas). To this corresponds totality (universitas) of +conditions in the synthesis of intuitions. The transcendental +conception of reason is therefore nothing else than the conception +of the totality of the conditions of a given conditioned. Now as the +unconditioned alone renders possible totality of conditions, and, +conversely, the totality of conditions is itself always unconditioned; +a pure rational conception in general can be defined and explained +by means of the conception of the unconditioned, in so far as it +contains a basis for the synthesis of the conditioned. + +To the number of modes of relation which the understanding cogitates +by means of the categories, the number of pure rational conceptions +will correspond. We must therefore seek for, first, an unconditioned +of the categorical synthesis in a subject; secondly, of the +hypothetical synthesis of the members of a series; thirdly, of the +disjunctive synthesis of parts in a system. + +There are exactly the same number of modes of syllogisms, each of +which proceeds through prosyllogisms to the unconditioned--one to +the subject which cannot be employed as predicate, another to the +presupposition which supposes nothing higher than itself, and the +third to an aggregate of the members of the complete division of a +conception. Hence the pure rational conceptions of totality in the +synthesis of conditions have a necessary foundation in the nature of +human reason--at least as modes of elevating the unity of the +understanding to the unconditioned. They may have no valid +application, corresponding to their transcendental employment, in +concreto, and be thus of no greater utility than to direct the +understanding how, while extending them as widely as possible, to +maintain its exercise and application in perfect consistence and +harmony. + +But, while speaking here of the totality of conditions and of the +unconditioned as the common title of all conceptions of reason, we +again light upon an expression which we find it impossible to dispense +with, and which nevertheless, owing to the ambiguity attaching to it +from long abuse, we cannot employ with safety. The word absolute is +one of the few words which, in its original signification, was +perfectly adequate to the conception it was intended to convey--a +conception which no other word in the same language exactly suits, +and the loss--or, which is the same thing, the incautious and loose +employment--of which must be followed by the loss of the conception +itself. And, as it is a conception which occupies much of the +attention of reason, its loss would be greatly to the detriment of +all transcendental philosophy. The word absolute is at present +frequently used to denote that something can be predicated of a +thing considered in itself and intrinsically. In this sense absolutely +possible would signify that which is possible in itself (interne)- +which is, in fact, the least that one can predicate of an object. On +the other hand, it is sometimes employed to indicate that a thing is +valid in all respects--for example, absolute sovereignty. Absolutely +possible would in this sense signify that which is possible in all +relations and in every respect; and this is the most that can be +predicated of the possibility of a thing. Now these significations +do in truth frequently coincide. Thus, for example, that which is +intrinsically impossible, is also impossible in all relations, that +is, absolutely impossible. But in most cases they differ from each +other toto caelo, and I can by no means conclude that, because a thing +is in itself possible, it is also possible in all relations, and +therefore absolutely. Nay, more, I shall in the sequel show that +absolute necessity does not by any means depend on internal necessity, +and that, therefore, it must not be considered as synonymous with +it. Of an opposite which is intrinsically impossible, we may affirm +that it is in all respects impossible, and that, consequently, the +thing itself, of which this is the opposite, is absolutely +necessary; but I cannot reason conversely and say, the opposite of +that which is absolutely necessary is intrinsically impossible, that +is, that the absolute necessity of things is an internal necessity. +For this internal necessity is in certain cases a mere empty word with +which the least conception cannot be connected, while the conception +of the necessity of a thing in all relations possesses very peculiar +determinations. Now as the loss of a conception of great utility in +speculative science cannot be a matter of indifference to the +philosopher, I trust that the proper determination and careful +preservation of the expression on which the conception depends will +likewise be not indifferent to him. + +In this enlarged signification, then, shall I employ the word +absolute, in opposition to that which is valid only in some particular +respect; for the latter is restricted by conditions, the former is +valid without any restriction whatever. + +Now the transcendental conception of reason has for its object +nothing else than absolute totality in the synthesis of conditions +and does not rest satisfied till it has attained to the absolutely, +that is, in all respects and relations, unconditioned. For pure reason +leaves to the understanding everything that immediately relates to +the object of intuition or rather to their synthesis in imagination. +The former restricts itself to the absolute totality in the employment +of the conceptions of the understanding and aims at carrying out the +synthetical unity which is cogitated in the category, even to the +unconditioned. This unity may hence be called the rational unity of +phenomena, as the other, which the category expresses, may be termed +the unity of the understanding. Reason, therefore, has an immediate +relation to the use of the understanding, not indeed in so far as +the latter contains the ground of possible experience (for the +conception of the absolute totality of conditions is not a +conception that can be employed in experience, because no experience +is unconditioned), but solely for the purpose of directing it to a +certain unity, of which the understanding has no conception, and the +aim of which is to collect into an absolute whole all acts of the +understanding. Hence the objective employment of the pure +conceptions of reason is always transcendent, while that of the pure +conceptions of the understanding must, according to their nature, be +always immanent, inasmuch as they are limited to possible experience. + +I understand by idea a necessary conception of reason, to which no +corresponding object can be discovered in the world of sense. +Accordingly, the pure conceptions of reason at present under +consideration are transcendental ideas. They are conceptions of pure +reason, for they regard all empirical cognition as determined by means +of an absolute totality of conditions. They are not mere fictions, +but natural and necessary products of reason, and have hence a necessary +relation to the whole sphere of the exercise of the understanding. +And, finally, they are transcendent, and overstep the limits of all +experiences, in which, consequently, no object can ever be presented +that would be perfectly adequate to a transcendental idea. When we +use the word idea, we say, as regards its object (an object of the +pure understanding), a great deal, but as regards its subject (that +is, in respect of its reality under conditions of experience), exceedingly +little, because the idea, as the conception of a maximum, can never +be completely and adequately presented in concreto. Now, as in the +merely speculative employment of reason the latter is properly the +sole aim, and as in this case the approximation to a conception, which +is never attained in practice, is the same thing as if the conception +were non-existent--it is commonly said of the conception of this kind, +"it is only an idea." So we might very well say, "the absolute +totality of all phenomena is only an idea," for, as we never can +present an adequate representation of it, it remains for us a +problem incapable of solution. On the other hand, as in the +practical use of the understanding we have only to do with action +and practice according to rules, an idea of pure reason can always +be given really in concreto, although only partially, nay, it is the +indispensable condition of all practical employment of reason. The +practice or execution of the idea is always limited and defective, +but nevertheless within indeterminable boundaries, consequently always +under the influence of the conception of an absolute perfection. And +thus the practical idea is always in the highest degree fruitful, +and in relation to real actions indispensably necessary. In the +idea, pure reason possesses even causality and the power of +producing that which its conception contains. Hence we cannot say of +wisdom, in a disparaging way, "it is only an idea." For, for the +very reason that it is the idea of the necessary unity of all possible +aims, it must be for all practical exertions and endeavours the +primitive condition and rule--a rule which, if not constitutive, is +at least limitative. + +Now, although we must say of the transcendental conceptions of +reason, "they are only ideas," we must not, on this account, look upon +them as superfluous and nugatory. For, although no object can be +determined by them, they can be of great utility, unobserved and at +the basis of the edifice of the understanding, as the canon for its +extended and self-consistent exercise--a canon which, indeed, does +not enable it to cognize more in an object than it would cognize by +the help of its own conceptions, but which guides it more securely +in its cognition. Not to mention that they perhaps render possible +a transition from our conceptions of nature and the non-ego to the +practical conceptions, and thus produce for even ethical ideas +keeping, so to speak, and connection with the speculative cognitions +of reason. The explication of all this must be looked for in the +sequel. + +But setting aside, in conformity with our original purpose, the +consideration of the practical ideas, we proceed to contemplate reason +in its speculative use alone, nay, in a still more restricted +sphere, to wit, in the transcendental use; and here must strike into +the same path which we followed in our deduction of the categories. +That is to say, we shall consider the logical form of the cognition +of reason, that we may see whether reason may not be thereby a source +of conceptions which enables us to regard objects in themselves as +determined synthetically a priori, in relation to one or other of +the functions of reason. + +Reason, considered as the faculty of a certain logical form of +cognition, is the faculty of conclusion, that is, of mediate +judgement--by means of the subsumption of the condition of a possible +judgement under the condition of a given judgement. The given judgement +is the general rule (major). The subsumption of the condition of +another possible judgement under the condition of the rule is the +minor. The actual judgement, which enounces the assertion of the rule +in the subsumed case, is the conclusion (conclusio). The rule +predicates something generally under a certain condition. The condition +of the rule is satisfied in some particular case. It follows that what +was valid in general under that condition must also be considered as +valid in the particular case which satisfies this condition. It is very +plain that reason attains to a cognition, by means of acts of the +understanding which constitute a series of conditions. When I arrive at +the proposition, "All bodies are changeable," by beginning with the +more remote cognition (in which the conception of body does not appear, +but which nevertheless contains the condition of that conception), "All +compound is changeable," by proceeding from this to a less remote +cognition, which stands under the condition of the former, "Bodies are +compound," and hence to a third, which at length connects for me the +remote cognition (changeable) with the one before me, "Consequently, +bodies are changeable"--I have arrived at a cognition (conclusion) +through a series of conditions (premisses). Now every series, whose +exponent (of the categorical or hypothetical judgement) is given, can +be continued; consequently the same procedure of reason conducts us to +the ratiocinatio polysyllogistica, which is a series of syllogisms, +that can be continued either on the side of the conditions (per +prosyllogismos) or of the conditioned (per episyllogismos) to an +indefinite extent. + +But we very soon perceive that the chain or series of prosyllogisms, +that is, of deduced cognitions on the side of the grounds or +conditions of a given cognition, in other words, the ascending +series of syllogisms must have a very different relation to the +faculty of reason from that of the descending series, that is, the +progressive procedure of reason on the side of the conditioned by +means of episyllogisms. For, as in the former case the cognition +(conclusio) is given only as conditioned, reason can attain to this +cognition only under the presupposition that all the members of the +series on the side of the conditions are given (totality in the series +of premisses), because only under this supposition is the judgement +we may be considering possible a priori; while on the side of the +conditioned or the inferences, only an incomplete and becoming, and +not a presupposed or given series, consequently only a potential +progression, is cogitated. Hence, when a cognition is contemplated +as conditioned, reason is compelled to consider the series of +conditions in an ascending line as completed and given in their +totality. But if the very same condition is considered at the same +time as the condition of other cognitions, which together constitute +a series of inferences or consequences in a descending line, reason +may preserve a perfect indifference, as to how far this progression +may extend a parte posteriori, and whether the totality of this series +is possible, because it stands in no need of such a series for the +purpose of arriving at the conclusion before it, inasmuch as this +conclusion is sufficiently guaranteed and determined on grounds a +parte priori. It may be the case, that upon the side of the conditions +the series of premisses has a first or highest condition, or it may +not possess this, and so be a parte priori unlimited; but it must, +nevertheless, contain totality of conditions, even admitting that we +never could succeed in completely apprehending it; and the whole +series must be unconditionally true, if the conditioned, which is +considered as an inference resulting from it, is to be held as true. +This is a requirement of reason, which announces its cognition as +determined a priori and as necessary, either in itself--and in this +case it needs no grounds to rest upon--or, if it is deduced, as a +member of a series of grounds, which is itself unconditionally true. + + + +SECTION III. System of Transcendental Ideas. + +We are not at present engaged with a logical dialectic, which +makes complete abstraction of the content of cognition and aims only +at unveiling the illusory appearance in the form of syllogisms. Our +subject is transcendental dialectic, which must contain, completely +a priori, the origin of certain cognitions drawn from pure reason, +and the origin of certain deduced conceptions, the object of which +cannot be given empirically and which therefore lie beyond the +sphere of the faculty of understanding. We have observed, from the +natural relation which the transcendental use of our cognition, in +syllogisms as well as in judgements, must have to the logical, that +there are three kinds of dialectical arguments, corresponding to the +three modes of conclusion, by which reason attains to cognitions on +principles; and that in all it is the business of reason to ascend +from the conditioned synthesis, beyond which the understanding never +proceeds, to the unconditioned which the understanding never can +reach. + +Now the most general relations which can exist in our +representations are: 1st, the relation to the subject; 2nd, the +relation to objects, either as phenomena, or as objects of thought +in general. If we connect this subdivision with the main division, +all the relations of our representations, of which we can form either +a conception or an idea, are threefold: 1. The relation to the +subject; 2. The relation to the manifold of the object as a +phenomenon; 3. The relation to all things in general. + +Now all pure conceptions have to do in general with the +synthetical unity of representations; conceptions of pure reason +(transcendental ideas), on the other hand, with the unconditional +synthetical unity of all conditions. It follows that all +transcendental ideas arrange themselves in three classes, the first +of which contains the absolute (unconditioned) unity of the thinking +subject, the second the absolute unity of the series of the conditions +of a phenomenon, the third the absolute unity of the condition of +all objects of thought in general. + +The thinking subject is the object-matter of Psychology; the sum +total of all phenomena (the world) is the object-matter of +Cosmology; and the thing which contains the highest condition of the +possibility of all that is cogitable (the being of all beings) is +the object-matter of all Theology. Thus pure reason presents us with +the idea of a transcendental doctrine of the soul (psychologia +rationalis), of a transcendental science of the world (cosmologia +rationalis), and finally of a transcendental doctrine of God +(theologia transcendentalis). Understanding cannot originate even +the outline of any of these sciences, even when connected with the +highest logical use of reason, that is, all cogitable syllogisms- +for the purpose of proceeding from one object (phenomenon) to all +others, even to the utmost limits of the empirical synthesis. They +are, on the contrary, pure and genuine products, or problems, of +pure reason. + +What modi of the pure conceptions of reason these transcendental +ideas are will be fully exposed in the following chapter. They +follow the guiding thread of the categories. For pure reason never +relates immediately to objects, but to the conceptions of these +contained in the understanding. In like manner, it will be made +manifest in the detailed explanation of these ideas--how reason, +merely through the synthetical use of the same function which it +employs in a categorical syllogism, necessarily attains to the +conception of the absolute unity of the thinking subject--how the +logical procedure in hypothetical ideas necessarily produces the +idea of the absolutely unconditioned in a series of given +conditions, and finally--how the mere form of the disjunctive +syllogism involves the highest conception of a being of all beings: +a thought which at first sight seems in the highest degree +paradoxical. + +An objective deduction, such as we were able to present in the +case of the categories, is impossible as regards these +transcendental ideas. For they have, in truth, no relation to any +object, in experience, for the very reason that they are only ideas. +But a subjective deduction of them from the nature of our reason is +possible, and has been given in the present chapter. + +It is easy to perceive that the sole aim of pure reason is the +absolute totality of the synthesis on the side of the conditions, +and that it does not concern itself with the absolute completeness +on the Part of the conditioned. For of the former alone does she stand +in need, in order to preposit the whole series of conditions, and thus +present them to the understanding a priori. But if we once have a +completely (and unconditionally) given condition, there is no +further necessity, in proceeding with the series, for a conception +of reason; for the understanding takes of itself every step +downward, from the condition to the conditioned. Thus the +transcendental ideas are available only for ascending in the series +of conditions, till we reach the unconditioned, that is, principles. +As regards descending to the conditioned, on the other hand, we find +that there is a widely extensive logical use which reason makes of +the laws of the understanding, but that a transcendental use thereof +is impossible; and that when we form an idea of the absolute totality +of such a synthesis, for example, of the whole series of all future +changes in the world, this idea is a mere ens rationis, an arbitrary +fiction of thought, and not a necessary presupposition of reason. +For the possibility of the conditioned presupposes the totality of +its conditions, but not of its consequences. Consequently, this conception +is not a transcendental idea--and it is with these alone that we are +at present occupied. + +Finally, it is obvious that there exists among the transcendental +ideas a certain connection and unity, and that pure reason, by means +of them, collects all its cognitions into one system. From the +cognition of self to the cognition of the world, and through these +to the supreme being, the progression is so natural, that it seems +to resemble the logical march of reason from the premisses to the +conclusion.* Now whether there lies unobserved at the foundation of +these ideas an analogy of the same kind as exists between the +logical and transcendental procedure of reason, is another of those +questions, the answer to which we must not expect till we arrive at +a more advanced stage in our inquiries. In this cursory and +preliminary view, we have, meanwhile, reached our aim. For we have +dispelled the ambiguity which attached to the transcendental +conceptions of reason, from their being commonly mixed up with other +conceptions in the systems of philosophers, and not properly +distinguished from the conceptions of the understanding; we have +exposed their origin and, thereby, at the same time their +determinate number, and presented them in a systematic connection, +and have thus marked out and enclosed a definite sphere for pure reason. + + +[*Footnote: The science of Metaphysics has for the proper object of +its inquiries only three grand ideas: GOD, FREEDOM, and IMMORTALITY, +and it aims at showing, that the second conception, conjoined with +the first, must lead to the third, as a necessary conclusion. All the +other subjects with which it occupies itself, are merely means for +the attainment and realization of these ideas. It does not require +these ideas for the construction of a science of nature, but, on the +contrary, for the purpose of passing beyond the sphere of nature. A +complete insight into and comprehension of them would render Theology, +Ethics, and, through the conjunction of both, Religion, solely +dependent on the speculative faculty of reason. In a systematic +representation of these ideas the above-mentioned arrangement--the +synthetical one--would be the most suitable; but in the +investigation which must necessarily precede it, the analytical, which +reverses this arrangement, would be better adapted to our purpose, +as in it we should proceed from that which experience immediately +presents to us--psychology, to cosmology, and thence to theology.] + + + +BOOK II. + +OF THE DIALECTICAL PROCEDURE OF PURE REASON. + +It may be said that the object of a merely transcendental idea is +something of which we have no conception, although the idea may be +a necessary product of reason according to its original laws. For, +in fact, a conception of an object that is adequate to the idea given +by reason, is impossible. For such an object must be capable of +being presented and intuited in a Possible experience. But we should +express our meaning better, and with less risk of being misunderstood, +if we said that we can have no knowledge of an object, which perfectly +corresponds to an idea, although we may possess a problematical +conception thereof. + +Now the transcendental (subjective) reality at least of the pure +conceptions of reason rests upon the fact that we are led to such +ideas by a necessary procedure of reason. There must therefore be +syllogisms which contain no empirical premisses, and by means of which +we conclude from something that we do know, to something of which we +do not even possess a conception, to which we, nevertheless, by an +unavoidable illusion, ascribe objective reality. Such arguments are, +as regards their result, rather to be termed sophisms than syllogisms, +although indeed, as regards their origin, they are very well +entitled to the latter name, inasmuch as they are not fictions or +accidental products of reason, but are necessitated by its very +nature. They are sophisms, not of men, but of pure reason herself, +from which the Wisest cannot free himself. After long labour he may +be able to guard against the error, but he can never be thoroughly +rid of the illusion which continually mocks and misleads him. + +Of these dialectical arguments there are three kinds, +corresponding to the number of the ideas which their conclusions +present. In the argument or syllogism of the first class, I +conclude, from the transcendental conception of the subject contains +no manifold, the absolute unity of the subject itself, of which I +cannot in this manner attain to a conception. This dialectical +argument I shall call the transcendental paralogism. The second +class of sophistical arguments is occupied with the transcendental +conception of the absolute totality of the series of conditions for +a given phenomenon, and I conclude, from the fact that I have always +a self-contradictory conception of the unconditioned synthetical unity +of the series upon one side, the truth of the opposite unity, of which +I have nevertheless no conception. The condition of reason in these +dialectical arguments, I shall term the antinomy of pure reason. +Finally, according to the third kind of sophistical argument, I +conclude, from the totality of the conditions of thinking objects in +general, in so far as they can be given, the absolute synthetical +unity of all conditions of the possibility of things in general; +that is, from things which I do not know in their mere +transcendental conception, I conclude a being of all beings which I +know still less by means of a transcendental conception, and of +whose unconditioned necessity I can form no conception whatever. +This dialectical argument I shall call the ideal of pure reason. + + + +CHAPTER I. Of the Paralogisms of Pure Reason. + +The logical paralogism consists in the falsity of an argument in +respect of its form, be the content what it may. But a +transcendental paralogism has a transcendental foundation, and +concludes falsely, while the form is correct and unexceptionable. In +this manner the paralogism has its foundation in the nature of human +reason, and is the parent of an unavoidable, though not insoluble, +mental illusion. + +We now come to a conception which was not inserted in the general +list of transcendental conceptions, and yet must be reckoned with +them, but at the same time without in the least altering, or +indicating a deficiency in that table. This is the conception, or, +if the term is preferred, the judgement, "I think." But it is +readily perceived that this thought is as it were the vehicle of all +conceptions in general, and consequently of transcendental conceptions +also, and that it is therefore regarded as a transcendental +conception, although it can have no peculiar claim to be so ranked, +inasmuch as its only use is to indicate that all thought is +accompanied by consciousness. At the same time, pure as this +conception is from empirical content (impressions of the senses), it +enables us to distinguish two different kinds of objects. "I," as +thinking, am an object of the internal sense, and am called soul. That +which is an object of the external senses is called body. Thus the +expression, "I," as a thinking being, designates the object-matter +of psychology, which may be called "the rational doctrine of the +soul," inasmuch as in this science I desire to know nothing of the +soul but what, independently of all experience (which determines me +in concreto), may be concluded from this conception "I," in so far +as it appears in all thought. + +Now, the rational doctrine of the soul is really an undertaking of +this kind. For if the smallest empirical element of thought, if any +particular perception of my internal state, were to be introduced +among the grounds of cognition of this science, it would not be a +rational, but an empirical doctrine of the soul. We have thus before +us a pretended science, raised upon the single proposition, "I think," +whose foundation or want of foundation we may very properly, and +agreeably with the nature of a transcendental philosophy, here +examine. It ought not to be objected that in this proposition, which +expresses the perception of one's self, an internal experience is +asserted, and that consequently the rational doctrine of the soul +which is founded upon it, is not pure, but partly founded upon an +empirical principle. For this internal perception is nothing more than +the mere apperception, "I think," which in fact renders all +transcendental conceptions possible, in which we say, "I think +substance, cause, etc." For internal experience in general and its +possibility, or perception in general, and its relation to other +perceptions, unless some particular distinction or determination +thereof is empirically given, cannot be regarded as empirical +cognition, but as cognition of the empirical, and belongs to the +investigation of the possibility of every experience, which is +certainly transcendental. The smallest object of experience (for +example, only pleasure or pain), that should be included in the +general representation of self-consciousness, would immediately change +the rational into an empirical psychology. + +"I think" is therefore the only text of rational psychology, from +which it must develop its whole system. It is manifest that this +thought, when applied to an object (myself), can contain nothing but +transcendental predicates thereof; because the least empirical +predicate would destroy the purity of the science and its independence +of all experience. + +But we shall have to follow here the guidance of the categories- +only, as in the present case a thing, "I," as thinking being, is at +first given, we shall--not indeed change the order of the categories +as it stands in the table--but begin at the category of substance, +by which at the a thing in itself is represented and proceeds +backwards through the series. The topic of the rational doctrine of +the soul, from which everything else it may contain must be deduced, +is accordingly as follows: + + + 1 2 + The Soul is SUBSTANCE As regards its quality + it is SIMPLE + + 3 + As regards the different + times in which it exists, + it is numerically identical, + that is UNITY, not Plurality. + + 4 + It is in relation to possible objects in space* + + +[*Footnote: The reader, who may not so easily perceive the +psychological sense of these expressions, taken here in their +transcendental abstraction, and cannot guess why the latter attribute +of the soul belongs to the category of existence, will find the +expressions sufficiently explained and justified in the sequel. I have, +moreover, to apologize for the Latin terms which have been employed, +instead of their German synonyms, contrary to the rules of correct +writing. But I judged it better to sacrifice elegance to perspicuity.] + +From these elements originate all the conceptions of pure +psychology, by combination alone, without the aid of any other +principle. This substance, merely as an object of the internal +sense, gives the conception of Immateriality; as simple substance, +that of Incorruptibility; its identity, as intellectual substance, +gives the conception of Personality; all these three together, +Spirituality. Its relation to objects in space gives us the conception +of connection (commercium) with bodies. Thus it represents thinking +substance as the principle of life in matter, that is, as a soul +(anima), and as the ground of Animality; and this, limited and +determined by the conception of spirituality, gives us that of +Immortality. + +Now to these conceptions relate four paralogisms of a transcendental +psychology, which is falsely held to be a science of pure reason, +touching the nature of our thinking being. We can, however, lay at +the foundation of this science nothing but the simple and in itself +perfectly contentless representation "I" which cannot even be called +a conception, but merely a consciousness which accompanies all +conceptions. By this "I," or "He," or "It," who or which thinks, +nothing more is represented than a transcendental subject of thought += x, which is cognized only by means of the thoughts that are its +predicates, and of which, apart from these, we cannot form the least +conception. Hence in a perpetual circle, inasmuch as we must always +employ it, in order to frame any judgement respecting it. And this +inconvenience we find it impossible to rid ourselves of, because +consciousness in itself is not so much a representation distinguishing +a particular object, as a form of representation in general, in so +far as it may be termed cognition; for in and by cognition alone do +I think anything. + +It must, however, appear extraordinary at first sight that the +condition under which I think, and which is consequently a property +of my subject, should be held to be likewise valid for every existence +which thinks, and that we can presume to base upon a seemingly +empirical proposition a judgement which is apodeictic and universal, +to wit, that everything which thinks is constituted as the voice of +my consciousness declares it to be, that is, as a self-conscious being. +The cause of this belief is to be found in the fact that we +necessarily attribute to things a priori all the properties which +constitute conditions under which alone we can cogitate them. Now I +cannot obtain the least representation of a thinking being by means +of external experience, but solely through self-consciousness. Such +objects are consequently nothing more than the transference of this +consciousness of mine to other things which can only thus be +represented as thinking beings. The proposition, "I think," is, in +the present case, understood in a problematical sense, not in so far +as it contains a perception of an existence (like the Cartesian "Cogito, +ergo sum"),[Footnote: "I think, therefore I am."] but in regard to +its mere possibility--for the purpose of discovering what properties +may be inferred from so simple a proposition and predicated of the +subject of it. + +If at the foundation of our pure rational cognition of thinking +beings there lay more than the mere Cogito--if we could likewise +call in aid observations on the play of our thoughts, and the thence +derived natural laws of the thinking self, there would arise an +empirical psychology which would be a kind of physiology of the +internal sense and might possibly be capable of explaining the +phenomena of that sense. But it could never be available for +discovering those properties which do not belong to possible +experience (such as the quality of simplicity), nor could it make +any apodeictic enunciation on the nature of thinking beings: it +would therefore not be a rational psychology. + +Now, as the proposition "I think" (in the problematical sense) +contains the form of every judgement in general and is the constant +accompaniment of all the categories, it is manifest that conclusions +are drawn from it only by a transcendental employment of the +understanding. This use of the understanding excludes all empirical +elements; and we cannot, as has been shown above, have any +favourable conception beforehand of its procedure. We shall +therefore follow with a critical eye this proposition through all +the predicaments of pure psychology; but we shall, for brevity's sake, +allow this examination to proceed in an uninterrupted connection. + +Before entering on this task, however, the following general +remark may help to quicken our attention to this mode of argument. +It is not merely through my thinking that I cognize an object, but +only through my determining a given intuition in relation to the unity +of consciousness in which all thinking consists. It follows that I +cognize myself, not through my being conscious of myself as +thinking, but only when I am conscious of the intuition of myself as +determined in relation to the function of thought. All the modi of +self-consciousness in thought are hence not conceptions of objects +(conceptions of the understanding--categories); they are mere +logical functions, which do not present to thought an object to be +cognized, and cannot therefore present my Self as an object. Not the +consciousness of the determining, but only that of the determinable +self, that is, of my internal intuition (in so far as the manifold +contained in it can be connected conformably with the general +condition of the unity of apperception in thought), is the object. + +1. In all judgements I am the determining subject of that relation +which constitutes a judgement. But that the I which thinks, must be +considered as in thought always a subject, and as a thing which cannot +be a predicate to thought, is an apodeictic and identical proposition. +But this proposition does not signify that I, as an object, am, for +myself, a self-subsistent being or substance. This latter statement- +an ambitious one--requires to be supported by data which are not to +be discovered in thought; and are perhaps (in so far as I consider +the thinking self merely as such) not to be discovered in the thinking +self at all. + +2. That the I or Ego of apperception, and consequently in all +thought, is singular or simple, and cannot be resolved into a +plurality of subjects, and therefore indicates a logically simple +subject--this is self-evident from the very conception of an Ego, +and is consequently an analytical proposition. But this is not +tantamount to declaring that the thinking Ego is a simple substance- +for this would be a synthetical proposition. The conception of +substance always relates to intuitions, which with me cannot be +other than sensuous, and which consequently lie completely out of +the sphere of the understanding and its thought: but to this sphere +belongs the affirmation that the Ego is simple in thought. It would +indeed be surprising, if the conception of "substance," which in other +cases requires so much labour to distinguish from the other elements +presented by intuition--so much trouble, too, to discover whether it +can be simple (as in the case of the parts of matter)--should be +presented immediately to me, as if by revelation, in the poorest +mental representation of all. + +3. The proposition of the identity of my Self amidst all the +manifold representations of which I am conscious, is likewise a +proposition lying in the conceptions themselves, and is consequently +analytical. But this identity of the subject, of which I am +conscious in all its representations, does not relate to or concern +the intuition of the subject, by which it is given as an object. +This proposition cannot therefore enounce the identity of the +person, by which is understood the consciousness of the identity of +its own substance as a thinking being in all change and variation of +circumstances. To prove this, we should require not a mere analysis +of the proposition, but synthetical judgements based upon a given +intuition. + +4. I distinguish my own existence, as that of a thinking being, from +that of other things external to me--among which my body also is +reckoned. This is also an analytical proposition, for other things +are exactly those which I think as different or distinguished from +myself. But whether this consciousness of myself is possible without +things external to me; and whether therefore I can exist merely as +a thinking being (without being man)--cannot be known or inferred from +this proposition. + +Thus we have gained nothing as regards the cognition of myself as +object, by the analysis of the consciousness of my Self in thought. +The logical exposition of thought in general is mistaken for a +metaphysical determination of the object. + +Our Critique would be an investigation utterly superfluous, if there +existed a possibility of proving a priori, that all thinking beings +are in themselves simple substances, as such, therefore, possess the +inseparable attribute of personality, and are conscious of their +existence apart from and unconnected with matter. For we should thus +have taken a step beyond the world of sense, and have penetrated +into the sphere of noumena; and in this case the right could not be +denied us of extending our knowledge in this sphere, of establishing +ourselves, and, under a favouring star, appropriating to ourselves +possessions in it. For the proposition: "Every thinking being, as +such, is simple substance," is an a priori synthetical proposition; +because in the first place it goes beyond the conception which is +the subject of it, and adds to the mere notion of a thinking being +the mode of its existence, and in the second place annexes a predicate +(that of simplicity) to the latter conception--a predicate which it +could not have discovered in the sphere of experience. It would follow +that a priori synthetical propositions are possible and legitimate, +not only, as we have maintained, in relation to objects of possible +experience, and as principles of the possibility of this experience +itself, but are applicable to things in themselves--an inference which +makes an end of the whole of this Critique, and obliges us to fall +back on the old mode of metaphysical procedure. But indeed the +danger is not so great, if we look a little closer into the question. + +There lurks in the procedure of rational Psychology a paralogism, +which is represented in the following syllogism: + +That which cannot be cogitated otherwise than as subject, does not +exist otherwise than as subject, and is therefore substance. + +A thinking being, considered merely as such, cannot be cogitated +otherwise than as subject. + +Therefore it exists also as such, that is, as substance. + +In the major we speak of a being that can be cogitated generally and +in every relation, consequently as it may be given in intuition. But +in the minor we speak of the same being only in so far as it regards +itself as subject, relatively to thought and the unity of +consciousness, but not in relation to intuition, by which it is +presented as an object to thought. Thus the conclusion is here arrived +at by a Sophisma figurae dictionis.* + +[*Footnote: Thought is taken in the two premisses in two totally +different senses. In the major it is considered as relating and applying +to objects in general, consequently to objects of intuition also. In the +minor, we understand it as relating merely to self-consciousness. In +this sense, we do not cogitate an object, but merely the relation to the +self-consciousness of the subject, as the form of thought. In the former +premiss we speak of things which cannot be cogitated otherwise than as +subjects. In the second, we do not speak of things, but of thought (all +objects being abstracted), in which the Ego is always the subject of +consciousness. Hence the conclusion cannot be, "I cannot exist otherwise +than as subject"; but only "I can, in cogitating my existence, employ my +Ego only as the subject of the judgement." But this is an identical +proposition, and throws no light on the mode of my existence.] + +That this famous argument is a mere paralogism, will be plain to any +one who will consider the general remark which precedes our exposition +of the principles of the pure understanding, and the section on +noumena. For it was there proved that the conception of a thing, which +can exist per se--only as a subject and never as a predicate, +possesses no objective reality; that is to say, we can never know +whether there exists any object to correspond to the conception; +consequently, the conception is nothing more than a conception, and +from it we derive no proper knowledge. If this conception is to +indicate by the term substance, an object that can be given, if it +is to become a cognition, we must have at the foundation of the +cognition a permanent intuition, as the indispensable condition of +its objective reality. For through intuition alone can an object be +given. But in internal intuition there is nothing permanent, for the +Ego is but the consciousness of my thought. If then, we appeal merely +to thought, we cannot discover the necessary condition of the application +of the conception of substance--that is, of a subject existing per +se--to the subject as a thinking being. And thus the conception of +the simple nature of substance, which is connected with the objective +reality of this conception, is shown to be also invalid, and to be, +in fact, nothing more than the logical qualitative unity of +self-consciousness in thought; whilst we remain perfectly ignorant +whether the subject is composite or not. + + + +Refutation of the Argument of Mendelssohn for the +Substantiality or Permanence of the Soul. + +This acute philosopher easily perceived the insufficiency of the +common argument which attempts to prove that the soul--it being +granted that it is a simple being--cannot perish by dissolution or +decomposition; he saw it is not impossible for it to cease to be by +extinction, or disappearance. He endeavoured to prove in his Phaedo, +that the soul cannot be annihilated, by showing that a simple being +cannot cease to exist. Inasmuch as, he said, a simple existence cannot +diminish, nor gradually lose portions of its being, and thus be by +degrees reduced to nothing (for it possesses no parts, and therefore +no multiplicity), between the moment in which it is, and the moment +in which it is not, no time can be discovered--which is impossible. +But this philosopher did not consider that, granting the soul to possess +this simple nature, which contains no parts external to each other +and consequently no extensive quantity, we cannot refuse to it any +less than to any other being, intensive quantity, that is, a degree +of reality in regard to all its faculties, nay, to all that constitutes +its existence. But this degree of reality can become less and less +through an infinite series of smaller degrees. It follows, +therefore, that this supposed substance--this thing, the permanence +of which is not assured in any other way, may, if not by decomposition, +by gradual loss (remissio) of its powers (consequently by +elanguescence, if I may employ this expression), be changed into +nothing. For consciousness itself has always a degree, which may be +lessened.* Consequently the faculty of being conscious may be +diminished; and so with all other faculties. The permanence of the +soul, therefore, as an object of the internal sense, remains +undemonstrated, nay, even indemonstrable. Its permanence in life is +evident, per se, inasmuch as the thinking being (as man) is to itself, +at the same time, an object of the external senses. But this does +not authorize the rational psychologist to affirm, from mere +conceptions, its permanence beyond life.*[2] + +[*Footnote: Clearness is not, as logicians maintain, the consciousness +of a representation. For a certain degree of consciousness, which may +not, however, be sufficient for recollection, is to be met with in +many dim representations. For without any consciousness at all, we +should not be able to recognize any difference in the obscure +representations we connect; as we really can do with many conceptions, +such as those of right and justice, and those of the musician, who +strikes at once several notes in improvising a piece of music. But +a representation is clear, in which our consciousness is sufficient +for the consciousness of the difference of this representation from +others. If we are only conscious that there is a difference, but are +not conscious of the difference--that is, what the difference is- +the representation must be termed obscure. There is, consequently, +an infinite series of degrees of consciousness down to its entire +disappearance.] + +[*[2]Footnote: There are some who think they have done enough to establish +a new possibility in the mode of the existence of souls, when they +have shown that there is no contradiction in their hypotheses on +this subject. Such are those who affirm the possibility of thought--of +which they have no other knowledge than what they derive from its +use in connecting empirical intuitions presented in this our human +life--after this life has ceased. But it is very easy to embarrass +them by the introduction of counter-possibilities, which rest upon +quite as good a foundation. Such, for example, is the possibility of +the division of a simple substance into several substances; and +conversely, of the coalition of several into one simple substance. +For, although divisibility presupposes composition, it does not +necessarily require a composition of substances, but only of the +degrees (of the several faculties) of one and the same substance. +Now we can cogitate all the powers and faculties of the soul--even +that of consciousness--as diminished by one half, the substance +still remaining. In the same way we can represent to ourselves without +contradiction, this obliterated half as preserved, not in the soul, +but without it; and we can believe that, as in this case every +thing that is real in the soul, and has a degree--consequently its +entire existence--has been halved, a particular substance would +arise out of the soul. For the multiplicity, which has been divided, +formerly existed, but not as a multiplicity of substances, but of +every reality as the quantum of existence in it; and the unity of +substance was merely a mode of existence, which by this division alone +has been transformed into a plurality of subsistence. In the same +manner several simple substances might coalesce into one, without +anything being lost except the plurality of subsistence, inasmuch as +the one substance would contain the degree of reality of all the +former substances. Perhaps, indeed, the simple substances, which +appear under the form of matter, might (not indeed by a mechanical +or chemical influence upon each other, but by an unknown influence, +of which the former would be but the phenomenal appearance), by means +of such a dynamical division of the parent-souls, as intensive +quantities, produce other souls, while the former repaired the loss +thus sustained with new matter of the same sort. I am far from +allowing any value to such chimeras; and the principles of our +analytic have clearly proved that no other than an empirical use of +the categories--that of substance, for example--is possible. But if +the rationalist is bold enough to construct, on the mere authority +of the faculty of thought--without any intuition, whereby an object +is given--a self-subsistent being, merely because the unity of +apperception in thought cannot allow him to believe it a composite +being, instead of declaring, as he ought to do, that he is unable to +explain the possibility of a thinking nature; what ought to hinder +the materialist, with as complete an independence of experience, to +employ the principle of the rationalist in a directly opposite manner-- +still preserving the formal unity required by his opponent?] + +If, now, we take the above propositions--as they must be accepted as +valid for all thinking beings in the system of rational psychology--in +synthetical connection, and proceed, from the category of relation, +with the proposition: "All thinking beings are, as such, substances," +backwards through the series, till the circle is completed; we come at +last to their existence, of which, in this system of rational +psychology, substances are held to be conscious, independently of +external things; nay, it is asserted that, in relation to the +permanence which is a necessary characteristic of substance, they can +of themselves determine external things. It follows that idealism--at +least problematical idealism, is perfectly unavoidable in this +rationalistic system. And, if the existence of outward things is not +held to be requisite to the determination of the existence of a +substance in time, the existence of these outward things at all, is a +gratuitous assumption which remains without the possibility of a proof. + +But if we proceed analytically--the "I think" as a proposition +containing in itself an existence as given, consequently modality +being the principle--and dissect this proposition, in order to +ascertain its content, and discover whether and how this Ego +determines its existence in time and space without the aid of anything +external; the propositions of rationalistic psychology would not begin +with the conception of a thinking being, but with a reality, and the +properties of a thinking being in general would be deduced from the +mode in which this reality is cogitated, after everything empirical +had been abstracted; as is shown in the following table: + + + 1 + I think, + + 2 3 + as Subject, as simple Subject, + + 4 + as identical Subject, + in every state of my thought. + + +Now, inasmuch as it is not determined in this second proposition, +whether I can exist and be cogitated only as subject, and not also +as a predicate of another being, the conception of a subject is here +taken in a merely logical sense; and it remains undetermined, +whether substance is to be cogitated under the conception or not. +But in the third proposition, the absolute unity of apperception- +the simple Ego in the representation to which all connection and +separation, which constitute thought, relate, is of itself +important; even although it presents us with no information about +the constitution or subsistence of the subject. Apperception is +something real, and the simplicity of its nature is given in the +very fact of its possibility. Now in space there is nothing real +that is at the same time simple; for points, which are the only simple +things in space, are merely limits, but not constituent parts of +space. From this follows the impossibility of a definition on the +basis of materialism of the constitution of my Ego as a merely +thinking subject. But, because my existence is considered in the first +proposition as given, for it does not mean, "Every thinking being +exists" (for this would be predicating of them absolute necessity), +but only, "I exist thinking"; the proposition is quite empirical, +and contains the determinability of my existence merely in relation +to my representations in time. But as I require for this purpose +something that is permanent, such as is not given in internal +intuition; the mode of my existence, whether as substance or as +accident, cannot be determined by means of this simple +self-consciousness. Thus, if materialism is inadequate to explain +the mode in which I exist, spiritualism is likewise as insufficient; +and the conclusion is that we are utterly unable to attain to any +knowledge of the constitution of the soul, in so far as relates to +the possibility of its existence apart from external objects. + +And, indeed, how should it be possible, merely by the aid of the +unity of consciousness--which we cognize only for the reason that it +is indispensable to the possibility of experience--to pass the +bounds of experience (our existence in this life); and to extend our +cognition to the nature of all thinking beings by means of the +empirical--but in relation to every sort of intuition, perfectly +undetermined--proposition, "I think"? + +There does not then exist any rational psychology as a doctrine +furnishing any addition to our knowledge of ourselves. It is nothing +more than a discipline, which sets impassable limits to speculative +reason in this region of thought, to prevent it, on the one hand, from +throwing itself into the arms of a soulless materialism, and, on the +other, from losing itself in the mazes of a baseless spiritualism. +It teaches us to consider this refusal of our reason to give any +satisfactory answer to questions which reach beyond the limits of this +our human life, as a hint to abandon fruitless speculation; and to +direct, to a practical use, our knowledge of ourselves--which, +although applicable only to objects of experience, receives its +principles from a higher source, and regulates its procedure as if +our destiny reached far beyond the boundaries of experience and life. + +From all this it is evident that rational psychology has its +origin in a mere misunderstanding. The unity of consciousness, which +lies at the basis of the categories, is considered to be an +intuition of the subject as an object; and the category of substance +is applied to the intuition. But this unity is nothing more than the +unity in thought, by which no object is given; to which therefore +the category of substance--which always presupposes a given intuition- +cannot be applied. Consequently, the subject cannot be cognized. The +subject of the categories cannot, therefore, for the very reason +that it cogitates these, frame any conception of itself as an object +of the categories; for, to cogitate these, it must lay at the +foundation its own pure self-consciousness--the very thing that it +wishes to explain and describe. In like manner, the subject, in +which the representation of time has its basis, cannot determine, +for this very reason, its own existence in time. Now, if the latter +is impossible, the former, as an attempt to determine itself by means +of the categories as a thinking being in general, is no less so.* + +[*Footnote: The "I think" is, as has been already stated, an empirical +proposition, and contains the proposition, "I exist." But I cannot say, +"Everything, which thinks, exists"; for in this case the property of +thought would constitute all beings possessing it, necessary beings. Hence +my existence cannot be considered as an inference from the proposition, +"I think," as Descartes maintained--because in this case the major +premiss, "Everything, which thinks, exists," must precede--but the two +propositions are identical. The proposition, "I think," expresses an +undetermined empirical intuition, that perception (proving consequently +that sensation, which must belong to sensibility, lies at the foundation +of this proposition); but it precedes experience, whose province it is +to determine an object of perception by means of the categories in +relation to time; and existence in this proposition is not a category, +as it does not apply to an undetermined given object, but only to one of +which we have a conception, and about which we wish to know whether it +does or does not exist, out of, and apart from this conception. An +undetermined perception signifies here merely something real that has +been given, only, however, to thought in general--but not as a +phenomenon, nor as a thing in itself (noumenon), but only as something +that really exists, and is designated as such in the proposition, "I +think." For it must be remarked that, when I call the proposition, "I +think," an empirical proposition, I do not thereby mean that the Ego in +the proposition is an empirical representation; on the contrary, it is +purely intellectual, because it belongs to thought in general. But +without some empirical representation, which presents to the mind +material for thought, the mental act, "I think," would not take place; +and the empirical is only the condition of the application or employment +of the pure intellectual faculty.] + +Thus, then, appears the vanity of the hope of establishing a cognition +which is to extend its rule beyond the limits of experience--a +cognition which is one of the highest interests of humanity; and thus is +proved the futility of the attempt of speculative philosophy in this +region of thought. But, in this interest of thought, the severity of +criticism has rendered to reason a not unimportant service, by the +demonstration of the impossibility of making any dogmatical affirmation +concerning an object of experience beyond the boundaries of experience. +She has thus fortified reason against all affirmations of the contrary. +Now, this can be accomplished in only two ways. Either our proposition +must be proved apodeictically; or, if this is unsuccessful, the sources +of this inability must be sought for, and, if these are discovered to +exist in the natural and necessary limitation of our reason, our +opponents must submit to the same law of renunciation and refrain from +advancing claims to dogmatic assertion. + +But the right, say rather the necessity to admit a future life, upon +principles of the practical conjoined with the speculative use of +reason, has lost nothing by this renunciation; for the merely +speculative proof has never had any influence upon the common reason of +men. It stands upon the point of a hair, so that even the schools have +been able to preserve it from falling only by incessantly discussing it +and spinning it like a top; and even in their eyes it has never been +able to present any safe foundation for the erection of a theory. The +proofs which have been current among men, preserve their value +undiminished; nay, rather gain in clearness and unsophisticated power, +by the rejection of the dogmatical assumptions of speculative reason. +For reason is thus confined within her own peculiar province--the +arrangement of ends or aims, which is at the same time the arrangement +of nature; and, as a practical faculty, without limiting itself to the +latter, it is justified in extending the former, and with it our own +existence, beyond the boundaries of experience and life. If we turn our +attention to the analogy of the nature of living beings in this world, +in the consideration of which reason is obliged to accept as a +principle that no organ, no faculty, no appetite is useless, and that +nothing is superfluous, nothing disproportionate to its use, nothing +unsuited to its end; but that, on the contrary, everything is perfectly +conformed to its destination in life--we shall find that man, who alone +is the final end and aim of this order, is still the only animal that +seems to be excepted from it. For his natural gifts--not merely as +regards the talents and motives that may incite him to employ them, but +especially the moral law in him--stretch so far beyond all mere earthly +utility and advantage, that he feels himself bound to prize the mere +consciousness of probity, apart from all advantageous consequences-- +even the shadowy gift of posthumous fame--above everything; and he is +conscious of an inward call to constitute himself, by his conduct in +this world--without regard to mere sublunary interests--the citizen of +a better. This mighty, irresistible proof--accompanied by an +ever-increasing knowledge of the conformability to a purpose in +everything we see around us, by the conviction of the boundless +immensity of creation, by the consciousness of a certain +illimitableness in the possible extension of our knowledge, and by a +desire commensurate therewith--remains to humanity, even after the +theoretical cognition of ourselves has failed to establish the +necessity of an existence after death. + + + +Conclusion of the Solution of the Psychological Paralogism. + +The dialectical illusion in rational psychology arises from our +confounding an idea of reason (of a pure intelligence) with the +conception--in every respect undetermined--of a thinking being in +general. I cogitate myself in behalf of a possible experience, at +the same time making abstraction of all actual experience; and infer +therefrom that I can be conscious of myself apart from experience +and its empirical conditions. I consequently confound the possible +abstraction of my empirically determined existence with the supposed +consciousness of a possible separate existence of my thinking self; +and I believe that I cognize what is substantial in myself as a +transcendental subject, when I have nothing more in thought than the +unity of consciousness, which lies at the basis of all determination +of cognition. + +The task of explaining the community of the soul with the body +does not properly belong to the psychology of which we are here +speaking; because it proposes to prove the personality of the soul +apart from this communion (after death), and is therefore transcendent +in the proper sense of the word, although occupying itself with an +object of experience--only in so far, however, as it ceases to be an +object of experience. But a sufficient answer may be found to the +question in our system. The difficulty which lies in the execution +of this task consists, as is well known, in the presupposed +heterogeneity of the object of the internal sense (the soul) and the +objects of the external senses; inasmuch as the formal condition of +the intuition of the one is time, and of that of the other space also. +But if we consider that both kinds of objects do not differ +internally, but only in so far as the one appears externally to the +other--consequently, that what lies at the basis of phenomena, as a +thing in itself, may not be heterogeneous; this difficulty disappears. +There then remains no other difficulty than is to be found in the +question--how a community of substances is possible; a question +which lies out of the region of psychology, and which the reader, +after what in our analytic has been said of primitive forces and +faculties, will easily judge to be also beyond the region of human +cognition. + + + +GENERAL REMARK + +On the Transition from Rational Psychology to Cosmology. + +The proposition, "I think," or, "I exist thinking," is an +empirical proposition. But such a proposition must be based on +empirical intuition, and the object cogitated as a phenomenon; and +thus our theory appears to maintain that the soul, even in thought, +is merely a phenomenon; and in this way our consciousness itself, in +fact, abuts upon nothing. + +Thought, per se, is merely the purely spontaneous logical function +which operates to connect the manifold of a possible intuition; and +it does not represent the subject of consciousness as a phenomenon--for +this reason alone, that it pays no attention to the question whether +the mode of intuiting it is sensuous or intellectual. I therefore do +not represent myself in thought either as I am, or as I appear to +myself; I merely cogitate myself as an object in general, of the +mode of intuiting which I make abstraction. When I represent myself +as the subject of thought, or as the ground of thought, these modes +of representation are not related to the categories of substance or +of cause; for these are functions of thought applicable only to our +sensuous intuition. The application of these categories to the Ego +would, however, be necessary, if I wished to make myself an object +of knowledge. But I wish to be conscious of myself only as thinking; +in what mode my Self is given in intuition, I do not consider, and +it may be that I, who think, am a phenomenon--although not in so far +as I am a thinking being; but in the consciousness of myself in mere +thought I am a being, though this consciousness does not present to +me any property of this being as material for thought. + +But the proposition, "I think," in so far as it declares, "I exist +thinking," is not the mere representation of a logical function. It +determines the subject (which is in this case an object also) in +relation to existence; and it cannot be given without the aid of the +internal sense, whose intuition presents to us an object, not as a +thing in itself, but always as a phenomenon. In this proposition there +is therefore something more to be found than the mere spontaneity of +thought; there is also the receptivity of intuition, that is, my +thought of myself applied to the empirical intuition of myself. Now, +in this intuition the thinking self must seek the conditions of the +employment of its logical functions as categories of substance, cause, +and so forth; not merely for the purpose of distinguishing itself as +an object in itself by means of the representation "I," but also for +the purpose of determining the mode of its existence, that is, of +cognizing itself as noumenon. But this is impossible, for the internal +empirical intuition is sensuous, and presents us with nothing but +phenomenal data, which do not assist the object of pure +consciousness in its attempt to cognize itself as a separate +existence, but are useful only as contributions to experience. + +But, let it be granted that we could discover, not in experience, but +in certain firmly-established a priori laws of the use of pure reason-- +laws relating to our existence, authority to consider ourselves as +legislating a priori in relation to our own existence and as +determining this existence; we should, on this supposition, find +ourselves possessed of a spontaneity, by which our actual existence +would be determinable, without the aid of the conditions of empirical +intuition. We should also become aware that in the consciousness of +our existence there was an a priori content, which would serve to +determine our own existence--an existence only sensuously +determinable--relatively, however, to a certain internal faculty +in relation to an intelligible world. + +But this would not give the least help to the attempts of rational +psychology. For this wonderful faculty, which the consciousness of +the moral law in me reveals, would present me with a principle of the +determination of my own existence which is purely intellectual--but +by what predicates? By none other than those which are given in +sensuous intuition. Thus I should find myself in the same position +in rational psychology which I formerly occupied, that is to say, I +should find myself still in need of sensuous intuitions, in order to +give significance to my conceptions of substance and cause, by means +of which alone I can possess a knowledge of myself: but these +intuitions can never raise me above the sphere of experience. I should +be justified, however, in applying these conceptions, in regard to +their practical use, which is always directed to objects of +experience--in conformity with their analogical significance when +employed theoretically--to freedom and its subject. At the same +time, I should understand by them merely the logical functions of +subject and predicate, of principle and consequence, in conformity +with which all actions are so determined, that they are capable of +being explained along with the laws of nature, conformably to the +categories of substance and cause, although they originate from a very +different principle. We have made these observations for the purpose +of guarding against misunderstanding, to which the doctrine of our +intuition of self as a phenomenon is exposed. We shall have occasion +to perceive their utility in the sequel. + + + +CHAPTER II. The Antinomy of Pure Reason. + +We showed in the introduction to this part of our work, that all +transcendental illusion of pure reason arose from dialectical +arguments, the schema of which logic gives us in its three formal +species of syllogisms--just as the categories find their logical +schema in the four functions of all judgements. The first kind of +these sophistical arguments related to the unconditioned unity of +the subjective conditions of all representations in general (of the +subject or soul), in correspondence with the categorical syllogisms, +the major of which, as the principle, enounces the relation of a +predicate to a subject. The second kind of dialectical argument will +therefore be concerned, following the analogy with hypothetical +syllogisms, with the unconditioned unity of the objective conditions +in the phenomenon; and, in this way, the theme of the third kind to +be treated of in the following chapter will be the unconditioned unity +of the objective conditions of the possibility of objects in general. + +But it is worthy of remark that the transcendental paralogism +produced in the mind only a one-third illusion, in regard to the +idea of the subject of our thought; and the conceptions of reason gave +no ground to maintain the contrary proposition. The advantage is +completely on the side of Pneumatism; although this theory itself +passes into naught, in the crucible of pure reason. + +Very different is the case when we apply reason to the objective +synthesis of phenomena. Here, certainly, reason establishes, with much +plausibility, its principle of unconditioned unity; but it very soon +falls into such contradictions that it is compelled, in relation to +cosmology, to renounce its pretensions. + +For here a new phenomenon of human reason meets us--a perfectly +natural antithetic, which does not require to be sought for by +subtle sophistry, but into which reason of itself unavoidably falls. +It is thereby preserved, to be sure, from the slumber of a fancied +conviction--which a merely one-sided illusion produces; but it is at +the same time compelled, either, on the one hand, to abandon itself +to a despairing scepticism, or, on the other, to assume a dogmatical +confidence and obstinate persistence in certain assertions, without +granting a fair hearing to the other side of the question. Either is +the death of a sound philosophy, although the former might perhaps +deserve the title of the euthanasia of pure reason. + +Before entering this region of discord and confusion, which the +conflict of the laws of pure reason (antinomy) produces, we shall +present the reader with some considerations, in explanation and +justification of the method we intend to follow in our treatment of +this subject. I term all transcendental ideas, in so far as they +relate to the absolute totality in the synthesis of phenomena, +cosmical conceptions; partly on account of this unconditioned +totality, on which the conception of the world-whole is based--a +conception, which is itself an idea--partly because they relate solely +to the synthesis of phenomena--the empirical synthesis; while, on +the other hand, the absolute totality in the synthesis of the +conditions of all possible things gives rise to an ideal of pure +reason, which is quite distinct from the cosmical conception, although +it stands in relation with it. Hence, as the paralogisms of pure +reason laid the foundation for a dialectical psychology, the +antinomy of pure reason will present us with the transcendental +principles of a pretended pure (rational) cosmology--not, however, +to declare it valid and to appropriate it, but--as the very term of +a conflict of reason sufficiently indicates, to present it as an +idea which cannot be reconciled with phenomena and experience. + + + +SECTION I. System of Cosmological Ideas. + +That We may be able to enumerate with systematic precision these +ideas according to a principle, we must remark, in the first place, +that it is from the understanding alone that pure and transcendental +conceptions take their origin; that the reason does not properly +give birth to any conception, but only frees the conception of the +understanding from the unavoidable limitation of a possible +experience, and thus endeavours to raise it above the empirical, +though it must still be in connection with it. This happens from the +fact that, for a given conditioned, reason demands absolute totality +on the side of the conditions (to which the understanding submits +all phenomena), and thus makes of the category a transcendental +idea. This it does that it may be able to give absolute completeness +to the empirical synthesis, by continuing it to the unconditioned +(which is not to be found in experience, but only in the idea). Reason +requires this according to the principle: If the conditioned is +given the whole of the conditions, and consequently the absolutely +unconditioned, is also given, whereby alone the former was possible. +First, then, the transcendental ideas are properly nothing but +categories elevated to the unconditioned; and they may be arranged +in a table according to the titles of the latter. But, secondly, all +the categories are not available for this purpose, but only those in +which the synthesis constitutes a series--of conditions subordinated +to, not co-ordinated with, each other. Absolute totality is required +of reason only in so far as concerns the ascending series of the +conditions of a conditioned; not, consequently, when the question +relates to the descending series of consequences, or to the +aggregate of the co-ordinated conditions of these consequences. For, +in relation to a given conditioned, conditions are presupposed and +considered to be given along with it. On the other hand, as the +consequences do not render possible their conditions, but rather +presuppose them--in the consideration of the procession of +consequences (or in the descent from the given condition to the +conditioned), we may be quite unconcerned whether the series ceases +or not; and their totality is not a necessary demand of reason. + +Thus we cogitate--and necessarily--a given time completely elapsed +up to a given moment, although that time is not determinable by us. +But as regards time future, which is not the condition of arriving +at the present, in order to conceive it; it is quite indifferent +whether we consider future time as ceasing at some point, or as +prolonging itself to infinity. Take, for example, the series m, n, +o, in which n is given as conditioned in relation to m, but at the +same time as the condition of o, and let the series proceed upwards +from the conditioned n to m (l, k, i, etc.), and also downwards from +the condition n to the conditioned o (p, q, r, etc.)--I must +presuppose the former series, to be able to consider n as given, and +n is according to reason (the totality of conditions) possible only +by means of that series. But its possibility does not rest on the +following series o, p, q, r, which for this reason cannot be +regarded as given, but only as capable of being given (dabilis). + +I shall term the synthesis of the series on the side of the +conditions--from that nearest to the given phenomenon up to the more +remote--regressive; that which proceeds on the side of the +conditioned, from the immediate consequence to the more remote, I +shall call the progressive synthesis. The former proceeds in +antecedentia, the latter in consequentia. The cosmological ideas are +therefore occupied with the totality of the regressive synthesis, +and proceed in antecedentia, not in consequentia. When the latter +takes place, it is an arbitrary and not a necessary problem of pure +reason; for we require, for the complete understanding of what is +given in a phenomenon, not the consequences which succeed, but the +grounds or principles which precede. + +In order to construct the table of ideas in correspondence with +the table of categories, we take first the two primitive quanta of +all our intuitions, time and space. Time is in itself a series (and +the formal condition of all series), and hence, in relation to a given +present, we must distinguish a priori in it the antecedentia as +conditions (time past) from the consequentia (time future). +Consequently, the transcendental idea of the absolute totality of +the series of the conditions of a given conditioned, relates merely +to all past time. According to the idea of reason, the whole past time, +as the condition of the given moment, is necessarily cogitated as +given. But, as regards space, there exists in it no distinction +between progressus and regressus; for it is an aggregate and not a +series--its parts existing together at the same time. I can consider +a given point of time in relation to past time only as conditioned, +because this given moment comes into existence only through the past +time rather through the passing of the preceding time. But as the +parts of space are not subordinated, but co-ordinated to each other, +one part cannot be the condition of the possibility of the other; +and space is not in itself, like time, a series. But the synthesis +of the manifold parts of space--(the syntheses whereby we apprehend +space)--is nevertheless successive; it takes place, therefore, in +time, and contains a series. And as in this series of aggregated +spaces (for example, the feet in a rood), beginning with a given +portion of space, those which continue to be annexed form the +condition of the limits of the former--the measurement of a space must +also be regarded as a synthesis of the series of the conditions of +a given conditioned. It differs, however, in this respect from that +of time, that the side of the conditioned is not in itself +distinguishable from the side of the condition; and, consequently, +regressus and progressus in space seem to be identical. But, +inasmuch as one part of space is not given, but only limited, by and +through another, we must also consider every limited space as +conditioned, in so far as it presupposes some other space as the +condition of its limitation, and so on. As regards limitation, +therefore, our procedure in space is also a regressus, and the +transcendental idea of the absolute totality of the synthesis in a +series of conditions applies to space also; and I am entitled to +demand the absolute totality of the phenomenal synthesis in space as +well as in time. Whether my demand can be satisfied is a question to +be answered in the sequel. + +Secondly, the real in space--that is, matter--is conditioned. Its +internal conditions are its parts, and the parts of parts its remote +conditions; so that in this case we find a regressive synthesis, the +absolute totality of which is a demand of reason. But this cannot be +obtained otherwise than by a complete division of parts, whereby the +real in matter becomes either nothing or that which is not matter, +that is to say, the simple. Consequently we find here also a series +of conditions and a progress to the unconditioned. + +Thirdly, as regards the categories of a real relation between +phenomena, the category of substance and its accidents is not suitable +for the formation of a transcendental idea; that is to say, reason has +no ground, in regard to it, to proceed regressively with conditions. +For accidents (in so far as they inhere in a substance) are +co-ordinated with each other, and do not constitute a series. And, in +relation to substance, they are not properly subordinated to it, but +are the mode of existence of the substance itself. The conception of +the substantial might nevertheless seem to be an idea of the +transcendental reason. But, as this signifies nothing more than the +conception of an object in general, which subsists in so far as we +cogitate in it merely a transcendental subject without any predicates; +and as the question here is of an unconditioned in the series of +phenomena--it is clear that the substantial can form no member thereof. +The same holds good of substances in community, which are mere +aggregates and do not form a series. For they are not subordinated to +each other as conditions of the possibility of each other; which, +however, may be affirmed of spaces, the limits of which are never +determined in themselves, but always by some other space. It is, +therefore, only in the category of causality that we can find a series +of causes to a given effect, and in which we ascend from the latter, as +the conditioned, to the former as the conditions, and thus answer the +question of reason. + +Fourthly, the conceptions of the possible, the actual, and the +necessary do not conduct us to any series--excepting only in so far +as the contingent in existence must always be regarded as conditioned, +and as indicating, according to a law of the understanding, a +condition, under which it is necessary to rise to a higher, till in +the totality of the series, reason arrives at unconditioned necessity. + +There are, accordingly, only four cosmological ideas, corresponding +with the four titles of the categories. For we can select only such as +necessarily furnish us with a series in the synthesis of the manifold. + + 1 + The absolute Completeness + of the + COMPOSITION + of the given totality of all phenomena. + + 2 + The absolute Completeness + of the + DIVISION + of given totality in a phenomenon. + + 3 + The absolute Completeness + of the + ORIGINATION + of a phenomenon. + + 4 + The absolute Completeness + of the DEPENDENCE of the EXISTENCE + of what is changeable in a phenomenon. + + +We must here remark, in the first place, that the idea of absolute +totality relates to nothing but the exposition of phenomena, and +therefore not to the pure conception of a totality of things. +Phenomena are here, therefore, regarded as given, and reason +requires the absolute completeness of the conditions of their +possibility, in so far as these conditions constitute a series- +consequently an absolutely (that is, in every respect) complete +synthesis, whereby a phenomenon can be explained according to the laws +of the understanding. + +Secondly, it is properly the unconditioned alone that reason seeks +in this serially and regressively conducted synthesis of conditions. +It wishes, to speak in another way, to attain to completeness in the +series of premisses, so as to render it unnecessary to presuppose +others. This unconditioned is always contained in the absolute +totality of the series, when we endeavour to form a representation +of it in thought. But this absolutely complete synthesis is itself +but an idea; for it is impossible, at least before hand, to know whether +any such synthesis is possible in the case of phenomena. When we +represent all existence in thought by means of pure conceptions of +the understanding, without any conditions of sensuous intuition, we +may say with justice that for a given conditioned the whole series +of conditions subordinated to each other is also given; for the former +is only given through the latter. But we find in the case of phenomena +a particular limitation of the mode in which conditions are given, +that is, through the successive synthesis of the manifold of +intuition, which must be complete in the regress. Now whether this +completeness is sensuously possible, is a problem. But the idea of +it lies in the reason--be it possible or impossible to connect with +the idea adequate empirical conceptions. Therefore, as in the absolute +totality of the regressive synthesis of the manifold in a phenomenon +(following the guidance of the categories, which represent it as a +series of conditions to a given conditioned) the unconditioned is +necessarily contained--it being still left unascertained whether and +how this totality exists; reason sets out from the idea of totality, +although its proper and final aim is the unconditioned--of the whole +series, or of a part thereof. + +This unconditioned may be cogitated--either as existing only in +the entire series, all the members of which therefore would be without +exception conditioned and only the totality absolutely +unconditioned--and in this case the regressus is called infinite; or +the absolutely unconditioned is only a part of the series, to which +the other members are subordinated, but which Is not itself +submitted to any other condition.* In the former case the series is +a parte priori unlimited (without beginning), that is, infinite, and +nevertheless completely given. But the regress in it is never +completed, and can only be called potentially infinite. In the +second case there exists a first in the series. This first is +called, in relation to past time, the beginning of the world; in +relation to space, the limit of the world; in relation to the parts +of a given limited whole, the simple; in relation to causes, absolute +spontaneity (liberty); and in relation to the existence of +changeable things, absolute physical necessity. + +[*Footnote: The absolute totality of the series of conditions to a +given conditioned is always unconditioned; because beyond it there +exist no other conditions, on which it might depend. But the absolute +totality of such a series is only an idea, or rather a problematical +conception, the possibility of which must be investigated- +particularly in relation to the mode in which the unconditioned, as +the transcendental idea which is the real subject of inquiry, may be +contained therein.] + +We possess two expressions, world and nature, which are generally +interchanged. The first denotes the mathematical total of all +phenomena and the totality of their synthesis--in its progress by +means of composition, as well as by division. And the world is +termed nature,* when it is regarded as a dynamical whole--when our +attention is not directed to the aggregation in space and time, for +the purpose of cogitating it as a quantity, but to the unity in the +existence of phenomena. In this case the condition of that which +happens is called a cause; the unconditioned causality of the cause +in a phenomenon is termed liberty; the conditioned cause is called +in a more limited sense a natural cause. The conditioned in existence +is termed contingent, and the unconditioned necessary. The +unconditioned necessity of phenomena may be called natural necessity. + +[*Footnote: Nature, understood adjective (formaliter), signifies the +complex of the determinations of a thing, connected according to an +internal principle of causality. On the other hand, we understand by +nature, substantive (materialiter), the sum total of phenomena, in +so far as they, by virtue of an internal principle of causality, are +connected with each other throughout. In the former sense we speak +of the nature of liquid matter, of fire, etc., and employ the word +only adjective; while, if speaking of the objects of nature, we have +in our minds the idea of a subsisting whole.] + +The ideas which we are at present engaged in discussing I have +called cosmological ideas; partly because by the term world is +understood the entire content of all phenomena, and our ideas are +directed solely to the unconditioned among phenomena; partly also, +because world, in the transcendental sense, signifies the absolute +totality of the content of existing things, and we are directing our +attention only to the completeness of the synthesis--although, +properly, only in regression. In regard to the fact that these ideas +are all transcendent, and, although they do not transcend phenomena +as regards their mode, but are concerned solely with the world of sense +(and not with noumena), nevertheless carry their synthesis to a degree +far above all possible experience--it still seems to me that we can, +with perfect propriety, designate them cosmical conceptions. As +regards the distinction between the mathematically and the dynamically +unconditioned which is the aim of the regression of the synthesis, +I should call the two former, in a more limited signification, +cosmical conceptions, the remaining two transcendent physical +conceptions. This distinction does not at present seem to be of +particular importance, but we shall afterwards find it to be of some +value. + + + +SECTION II. Antithetic of Pure Reason. + +Thetic is the term applied to every collection of dogmatical +propositions. By antithetic I do not understand dogmatical +assertions of the opposite, but the self-contradiction of seemingly +dogmatical cognitions (thesis cum antithesis), in none of which we +can discover any decided superiority. Antithetic is not, therefore, +occupied with one-sided statements, but is engaged in considering +the contradictory nature of the general cognitions of reason and its +causes. Transcendental antithetic is an investigation into the +antinomy of pure reason, its causes and result. If we employ our +reason not merely in the application of the principles of the +understanding to objects of experience, but venture with it beyond +these boundaries, there arise certain sophistical propositions or +theorems. These assertions have the following peculiarities: They +can find neither confirmation nor confutation in experience; and +each is in itself not only self-consistent, but possesses conditions +of its necessity in the very nature of reason--only that, unluckily, +there exist just as valid and necessary grounds for maintaining the +contrary proposition. + +The questions which naturally arise in the consideration of this +dialectic of pure reason, are therefore: 1st. In what propositions +is pure reason unavoidably subject to an antinomy? 2nd. What are the +causes of this antinomy? 3rd. Whether and in what way can reason +free itself from this self-contradiction? + +A dialectical proposition or theorem of pure reason must, +according to what has been said, be distinguishable from all +sophistical propositions, by the fact that it is not an answer to an +arbitrary question, which may be raised at the mere pleasure of any +person, but to one which human reason must necessarily encounter in +its progress. In the second place, a dialectical proposition, with +its opposite, does not carry the appearance of a merely artificial +illusion, which disappears as soon as it is investigated, but a +natural and unavoidable illusion, which, even when we are no longer +deceived by it, continues to mock us and, although rendered +harmless, can never be completely removed. + +This dialectical doctrine will not relate to the unity of +understanding in empirical conceptions, but to the unity of reason +in pure ideas. The conditions of this doctrine are--inasmuch as it +must, as a synthesis according to rules, be conformable to the +understanding, and at the same time as the absolute unity of the +synthesis, to the reason--that, if it is adequate to the unity of +reason, it is too great for the understanding, if according with the +understanding, it is too small for the reason. Hence arises a mutual +opposition, which cannot be avoided, do what we will. + +These sophistical assertions of dialectic open, as it were, a +battle-field, where that side obtains the victory which has been +permitted to make the attack, and he is compelled to yield who has +been unfortunately obliged to stand on the defensive. And hence, +champions of ability, whether on the right or on the wrong side, are +certain to carry away the crown of victory, if they only take care +to have the right to make the last attack, and are not obliged to +sustain another onset from their opponent. We can easily believe +that this arena has been often trampled by the feet of combatants, +that many victories have been obtained on both sides, but that the +last victory, decisive of the affair between the contending parties, +was won by him who fought for the right, only if his adversary was +forbidden to continue the tourney. As impartial umpires, we must lay +aside entirely the consideration whether the combatants are fighting +for the right or for the wrong side, for the true or for the false, +and allow the combat to be first decided. Perhaps, after they have +wearied more than injured each other, they will discover the +nothingness of their cause of quarrel and part good friends. + +This method of watching, or rather of originating, a conflict of +assertions, not for the purpose of finally deciding in favour of +either side, but to discover whether the object of the struggle is +not a mere illusion, which each strives in vain to reach, but which +would be no gain even when reached--this procedure, I say, may be +termed the sceptical method. It is thoroughly distinct from +scepticism--the principle of a technical and scientific ignorance, +which undermines the foundations of all knowledge, in order, if +possible, to destroy our belief and confidence therein. For the +sceptical method aims at certainty, by endeavouring to discover in +a conflict of this kind, conducted honestly and intelligently on both +sides, the point of misunderstanding; just as wise legislators derive, +from the embarrassment of judges in lawsuits, information in regard +to the defective and ill-defined parts of their statutes. The antinomy +which reveals itself in the application of laws, is for our limited +wisdom the best criterion of legislation. For the attention of reason, +which in abstract speculation does not easily become conscious of +its errors, is thus roused to the momenta in the determination of +its principles. + +But this sceptical method is essentially peculiar to +transcendental philosophy, and can perhaps be dispensed with in +every other field of investigation. In mathematics its use would be +absurd; because in it no false assertions can long remain hidden, +inasmuch as its demonstrations must always proceed under the +guidance of pure intuition, and by means of an always evident +synthesis. In experimental philosophy, doubt and delay may be very +useful; but no misunderstanding is possible, which cannot be easily +removed; and in experience means of solving the difficulty and putting +an end to the dissension must at last be found, whether sooner or +later. Moral philosophy can always exhibit its principles, with +their practical consequences, in concreto--at least in possible +experiences, and thus escape the mistakes and ambiguities of +abstraction. But transcendental propositions, which lay claim to +insight beyond the region of possible experience, cannot, on the one +hand, exhibit their abstract synthesis in any a priori intuition, nor, +on the other, expose a lurking error by the help of experience. +Transcendental reason, therefore, presents us with no other +criterion than that of an attempt to reconcile such assertions, and +for this purpose to permit a free and unrestrained conflict between +them. And this we now proceed to arrange.* + + +[*Footnote: The antinomies stand in the order of the four +transcendental ideas above detailed.] + + + +FIRST CONFLICT OF THE TRANSCENDENTAL IDEAS. + +THESIS. + +The world has a beginning in time, and is also limited in +regard to space. + + +PROOF. + +Granted that the world has no beginning in time; up to every given +moment of time, an eternity must have elapsed, and therewith passed +away an infinite series of successive conditions or states of things +in the world. Now the infinity of a series consists in the fact that +it never can be completed by means of a successive synthesis. It +follows that an infinite series already elapsed is impossible and +that, consequently, a beginning of the world is a necessary +condition of its existence. And this was the first thing to be proved. + +As regards the second, let us take the opposite for granted. In this +case, the world must be an infinite given total of coexistent +things. Now we cannot cogitate the dimensions of a quantity, which +is not given within certain limits of an intuition,* in any other +way than by means of the synthesis of its parts, and the total of such +a quantity only by means of a completed synthesis, or the repeated +addition of unity to itself. Accordingly, to cogitate the world, which +fills all spaces, as a whole, the successive synthesis of the parts +of an infinite world must be looked upon as completed, that is to say, +an infinite time must be regarded as having elapsed in the enumeration +of all co-existing things; which is impossible. For this reason an +infinite aggregate of actual things cannot be considered as a given +whole, consequently, not as a contemporaneously given whole. The world +is consequently, as regards extension in space, not infinite, but +enclosed in limits. And this was the second thing to be proved. + +[*Footnote: We may consider an undetermined quantity as a whole, when +it is enclosed within limits, although we cannot construct or ascertain +its totality by measurement, that is, by the successive synthesis of +its parts. For its limits of themselves determine its completeness +as a whole.] + + +ANTITHESIS. + +The world has no beginning, and no limits in space, but is, in +relation both to time and space, infinite. + + +PROOF. + +For let it be granted that it has a beginning. A beginning is an +existence which is preceded by a time in which the thing does not +exist. On the above supposition, it follows that there must have +been a time in which the world did not exist, that is, a void time. +But in a void time the origination of a thing is impossible; because +no part of any such time contains a distinctive condition of being, +in preference to that of non-being (whether the supposed thing +originate of itself, or by means of some other cause). Consequently, +many series of things may have a beginning in the world, but the world +itself cannot have a beginning, and is, therefore, in relation to past +time, infinite. + +As regards the second statement, let us first take the opposite +for granted--that the world is finite and limited in space; it follows +that it must exist in a void space, which is not limited. We should +therefore meet not only with a relation of things in space, but also +a relation of things to space. Now, as the world is an absolute whole, +out of and beyond which no object of intuition, and consequently no +correlate to which can be discovered, this relation of the world to +a void space is merely a relation to no object. But such a relation, +and consequently the limitation of the world by void space, is +nothing. Consequently, the world, as regards space, is not limited, +that is, it is infinite in regard to extension.* + + +[*Footnote: Space is merely the form of external intuition (formal +intuition), and not a real object which can be externally perceived. +Space, prior to all things which determine it (fill or limit it), +or, rather, which present an empirical intuition conformable to it, +is, under the title of absolute space, nothing but the mere +possibility of external phenomena, in so far as they either exist in +themselves, or can annex themselves to given intuitions. Empirical +intuition is therefore not a composition of phenomena and space (of +perception and empty intuition). The one is not the correlate of the +other in a synthesis, but they are vitally connected in the same +empirical intuition, as matter and form. If we wish to set one of +these two apart from the other--space from phenomena--there arise +all sorts of empty determinations of external intuition, which are +very far from being possible perceptions. For example, motion or +rest of the world in an infinite empty space, or a determination of +the mutual relation of both, cannot possibly be perceived, and is +therefore merely the predicate of a notional entity.] + + + +OBSERVATIONS ON THE FIRST ANTINOMY. + +ON THE THESIS. + +In bringing forward these conflicting arguments, I have not been +on the search for sophisms, for the purpose of availing myself of +special pleading, which takes advantage of the carelessness of the +opposite party, appeals to a misunderstood statute, and erects its +unrighteous claims upon an unfair interpretation. Both proofs +originate fairly from the nature of the case, and the advantage +presented by the mistakes of the dogmatists of both parties has been +completely set aside. + +The thesis might also have been unfairly demonstrated, by the +introduction of an erroneous conception of the infinity of a given +quantity. A quantity is infinite, if a greater than itself cannot +possibly exist. The quantity is measured by the number of given units- +which are taken as a standard--contained in it. Now no number can be +the greatest, because one or more units can always be added. It +follows that an infinite given quantity, consequently an infinite +world (both as regards time and extension) is impossible. It is, +therefore, limited in both respects. In this manner I might have +conducted my proof; but the conception given in it does not agree with +the true conception of an infinite whole. In this there is no +representation of its quantity, it is not said how large it is; +consequently its conception is not the conception of a maximum. We +cogitate in it merely its relation to an arbitrarily assumed unit, +in relation to which it is greater than any number. Now, just as the +unit which is taken is greater or smaller, the infinite will be +greater or smaller; but the infinity, which consists merely in the +relation to this given unit, must remain always the same, although +the absolute quantity of the whole is not thereby cognized. + +The true (transcendental) conception of infinity is: that the +successive synthesis of unity in the measurement of a given quantum +can never be completed.* Hence it follows, without possibility of +mistake, that an eternity of actual successive states up to a given +(the present) moment cannot have elapsed, and that the world must +therefore have a beginning. + +[*Footnote: The quantum in this sense contains a congeries of given +units, which is greater than any number--and this is the mathematical +conception of the infinite.] + +In regard to the second part of the thesis, the difficulty as to +an infinite and yet elapsed series disappears; for the manifold of +a world infinite in extension is contemporaneously given. But, in +order to cogitate the total of this manifold, as we cannot have the +aid of limits constituting by themselves this total in intuition, we +are obliged to give some account of our conception, which in this case +cannot proceed from the whole to the determined quantity of the parts, +but must demonstrate the possibility of a whole by means of a +successive synthesis of the parts. But as this synthesis must +constitute a series that cannot be completed, it is impossible for +us to cogitate prior to it, and consequently not by means of it, a +totality. For the conception of totality itself is in the present case +the representation of a completed synthesis of the parts; and this +completion, and consequently its conception, is impossible. + + + +ON THE ANTITHESIS. + +The proof in favour of the infinity of the cosmical succession and +the cosmical content is based upon the consideration that, in the +opposite case, a void time and a void space must constitute the limits +of the world. Now I am not unaware, that there are some ways of +escaping this conclusion. It may, for example, be alleged, that a +limit to the world, as regards both space and time, is quite possible, +without at the same time holding the existence of an absolute time +before the beginning of the world, or an absolute space extending +beyond the actual world--which is impossible. I am quite well +satisfied with the latter part of this opinion of the philosophers +of the Leibnitzian school. Space is merely the form of external +intuition, but not a real object which can itself be externally +intuited; it is not a correlate of phenomena, it is the form of +phenomena itself. Space, therefore, cannot be regarded as absolutely +and in itself something determinative of the existence of things, +because it is not itself an object, but only the form of possible +objects. Consequently, things, as phenomena, determine space; that +is to say, they render it possible that, of all the possible +predicates of space (size and relation), certain may belong to +reality. But we cannot affirm the converse, that space, as something +self-subsistent, can determine real things in regard to size or shape, +for it is in itself not a real thing. Space (filled or void)* may +therefore be limited by phenomena, but phenomena cannot be limited +by an empty space without them. This is true of time also. All this +being granted, it is nevertheless indisputable, that we must assume +these two nonentities, void space without and void time before the +world, if we assume the existence of cosmical limits, relatively to +space or time. + +[*Footnote: It is evident that what is meant here is, that empty space, +in so far as it is limited by phenomena--space, that is, within the +world--does not at least contradict transcendental principles, and +may therefore, as regards them, be admitted, although its possibility +cannot on that account be affirmed.] + +For, as regards the subterfuge adopted by those who endeavour to +evade the consequence--that, if the world is limited as to space and +time, the infinite void must determine the existence of actual +things in regard to their dimensions--it arises solely from the fact +that instead of a sensuous world, an intelligible world--of which +nothing is known--is cogitated; instead of a real beginning (an +existence, which is preceded by a period in which nothing exists), +an existence which presupposes no other condition than that of time; +and, instead of limits of extension, boundaries of the universe. But +the question relates to the mundus phaenomenon, and its quantity; +and in this case we cannot make abstraction of the conditions of +sensibility, without doing away with the essential reality of this +world itself. The world of sense, if it is limited, must necessarily +lie in the infinite void. If this, and with it space as the a priori +condition of the possibility of phenomena, is left out of view, the +whole world of sense disappears. In our problem is this alone +considered as given. The mundus intelligibilis is nothing but the +general conception of a world, in which abstraction has been made of +all conditions of intuition, and in relation to which no synthetical +proposition--either affirmative or negative--is possible. + + + +SECOND CONFLICT OF TRANSCENDENTAL IDEAS. + +THESIS. + +Every composite substance in the world consists of simple parts; and +there exists nothing that is not either itself simple, or composed +of simple parts. + + +PROOF. + +For, grant that composite substances do not consist of simple parts; +in this case, if all combination or composition were annihilated in +thought, no composite part, and (as, by the supposition, there do +not exist simple parts) no simple part would exist. Consequently, no +substance; consequently, nothing would exist. Either, then, it is +impossible to annihilate composition in thought; or, after such +annihilation, there must remain something that subsists without +composition, that is, something that is simple. But in the former case +the composite could not itself consist of substances, because with +substances composition is merely a contingent relation, apart from +which they must still exist as self-subsistent beings. Now, as this +case contradicts the supposition, the second must contain the truth- +that the substantial composite in the world consists of simple parts. + +It follows, as an immediate inference, that the things in the +world are all, without exception, simple beings--that composition is +merely an external condition pertaining to them--and that, although +we never can separate and isolate the elementary substances from the +state of composition, reason must cogitate these as the primary +subjects of all composition, and consequently, as prior thereto--and +as simple substances. + + +ANTITHESIS. + +No composite thing in the world consists of simple parts; and +there does not exist in the world any simple substance. + + +PROOF. + +Let it be supposed that a composite thing (as substance) consists of +simple parts. Inasmuch as all external relation, consequently all +composition of substances, is possible only in space; the space, +occupied by that which is composite, must consist of the same number +of parts as is contained in the composite. But space does not +consist of simple parts, but of spaces. Therefore, every part of the +composite must occupy a space. But the absolutely primary parts of +what is composite are simple. It follows that what is simple +occupies a space. Now, as everything real that occupies a space, +contains a manifold the parts of which are external to each other, +and is consequently composite--and a real composite, not of accidents +(for these cannot exist external to each other apart from substance), +but of substances--it follows that the simple must be a substantial +composite, which is self-contradictory. + +The second proposition of the antithesis--that there exists in the +world nothing that is simple--is here equivalent to the following: +The existence of the absolutely simple cannot be demonstrated from +any experience or perception either external or internal; and the +absolutely simple is a mere idea, the objective reality of which +cannot be demonstrated in any possible experience; it is consequently, +in the exposition of phenomena, without application and object. For, +let us take for granted that an object may be found in experience +for this transcendental idea; the empirical intuition of such an +object must then be recognized to contain absolutely no manifold +with its parts external to each other, and connected into unity. +Now, as we cannot reason from the non-consciousness of such a manifold +to the impossibility of its existence in the intuition of an object, +and as the proof of this impossibility is necessary for the +establishment and proof of absolute simplicity; it follows that this +simplicity cannot be inferred from any perception whatever. As, +therefore, an absolutely simple object cannot be given in any +experience, and the world of sense must be considered as the sum total +of all possible experiences: nothing simple exists in the world. + +This second proposition in the antithesis has a more extended aim +than the first. The first merely banishes the simple from the +intuition of the composite; while the second drives it entirely out +of nature. Hence we were unable to demonstrate it from the conception +of a given object of external intuition (of the composite), but we +were obliged to prove it from the relation of a given object to a +possible experience in general. + + + +OBSERVATIONS ON THE SECOND ANTINOMY. + +THESIS. + +When I speak of a whole, which necessarily consists of simple parts, +I understand thereby only a substantial whole, as the true +composite; that is to say, I understand that contingent unity of the +manifold which is given as perfectly isolated (at least in thought), +placed in reciprocal connection, and thus constituted a unity. Space +ought not to be called a compositum but a totum, for its parts are +possible in the whole, and not the whole by means of the parts. It +might perhaps be called a compositum ideale, but not a compositum +reale. But this is of no importance. As space is not a composite of +substances (and not even of real accidents), if I abstract all +composition therein--nothing, not even a point, remains; for a point +is possible only as the limit of a space--consequently of a composite. +Space and time, therefore, do not consist of simple parts. That +which belongs only to the condition or state of a substance, even +although it possesses a quantity (motion or change, for example), +likewise does not consist of simple parts. That is to say, a certain +degree of change does not originate from the addition of many simple +changes. Our inference of the simple from the composite is valid +only of self-subsisting things. But the accidents of a state are not +self-subsistent. The proof, then, for the necessity of the simple, +as the component part of all that is substantial and composite, may +prove a failure, and the whole case of this thesis be lost, if we +carry the proposition too far, and wish to make it valid of everything +that is composite without distinction--as indeed has really now and +then happened. Besides, I am here speaking only of the simple, in so +far as it is necessarily given in the composite--the latter being +capable of solution into the former as its component parts. The proper +signification of the word monas (as employed by Leibnitz) ought to +relate to the simple, given immediately as simple substance (for +example, in consciousness), and not as an element of the composite. +As an clement, the term atomus would be more appropriate. And as I +wish to prove the existence of simple substances, only in relation +to, and as the elements of, the composite, I might term the antithesis +of the second Antinomy, transcendental Atomistic. But as this word +has long been employed to designate a particular theory of corporeal +phenomena (moleculae), and thus presupposes a basis of empirical +conceptions, I prefer calling it the dialectical principle of +Monadology. + + +ANTITHESIS. + +Against the assertion of the infinite subdivisibility of matter +whose ground of proof is purely mathematical, objections have been +alleged by the Monadists. These objections lay themselves open, at +first sight, to suspicion, from the fact that they do not recognize +the clearest mathematical proofs as propositions relating to the +constitution of space, in so far as it is really the formal +condition of the possibility of all matter, but regard them merely +as inferences from abstract but arbitrary conceptions, which cannot +have any application to real things. Just as if it were possible to +imagine another mode of intuition than that given in the primitive +intuition of space; and just as if its a priori determinations did +not apply to everything, the existence of which is possible, from the +fact alone of its filling space. If we listen to them, we shall find +ourselves required to cogitate, in addition to the mathematical point, +which is simple--not, however, a part, but a mere limit of space- +physical points, which are indeed likewise simple, but possess the +peculiar property, as parts of space, of filling it merely by their +aggregation. I shall not repeat here the common and clear +refutations of this absurdity, which are to be found everywhere in +numbers: every one knows that it is impossible to undermine the +evidence of mathematics by mere discursive conceptions; I shall only +remark that, if in this case philosophy endeavours to gain an +advantage over mathematics by sophistical artifices, it is because +it forgets that the discussion relates solely to Phenomena and their +conditions. It is not sufficient to find the conception of the +simple for the pure conception of the composite, but we must +discover for the intuition of the composite (matter), the intuition +of the simple. Now this, according to the laws of sensibility, and +consequently in the case of objects of sense, is utterly impossible. +In the case of a whole composed of substances, which is cogitated +solely by the pure understanding, it may be necessary to be in +possession of the simple before composition is possible. But this does +not hold good of the Totum substantiale phaenomenon, which, as an +empirical intuition in space, possesses the necessary property of +containing no simple part, for the very reason that no part of space +is simple. Meanwhile, the Monadists have been subtle enough to +escape from this difficulty, by presupposing intuition and the +dynamical relation of substances as the condition of the possibility +of space, instead of regarding space as the condition of the +possibility of the objects of external intuition, that is, of +bodies. Now we have a conception of bodies only as phenomena, and, +as such, they necessarily presuppose space as the condition of all +external phenomena. The evasion is therefore in vain; as, indeed, we +have sufficiently shown in our Aesthetic. If bodies were things in +themselves, the proof of the Monadists would be unexceptionable. + +The second dialectical assertion possesses the peculiarity of having +opposed to it a dogmatical proposition, which, among all such +sophistical statements, is the only one that undertakes to prove in +the case of an object of experience, that which is properly a +transcendental idea--the absolute simplicity of substance. The +proposition is that the object of the internal sense, the thinking +Ego, is an absolute simple substance. Without at present entering upon +this subject--as it has been considered at length in a former chapter- +I shall merely remark that, if something is cogitated merely as an +object, without the addition of any synthetical determination of its +intuition--as happens in the case of the bare representation, I--it +is certain that no manifold and no composition can be perceived in +such a representation. As, moreover, the predicates whereby I cogitate +this object are merely intuitions of the internal sense, there cannot +be discovered in them anything to prove the existence of a manifold +whose parts are external to each other, and, consequently, nothing +to prove the existence of real composition. Consciousness, therefore, +is so constituted that, inasmuch as the thinking subject is at the +same time its own object, it cannot divide itself--although it can +divide its inhering determinations. For every object in relation to +itself is absolute unity. Nevertheless, if the subject is regarded +externally, as an object of intuition, it must, in its character of +phenomenon, possess the property of composition. And it must always +be regarded in this manner, if we wish to know whether there is or +is not contained in it a manifold whose parts are external to each +other. + + + +THIRD CONFLICT OF THE TRANSCENDENTAL IDEAS. + +THESIS. + +Causality according to the laws of nature, is not the only causality +operating to originate the phenomena of the world. A causality of +freedom is also necessary to account fully for these phenomena. + + +PROOF. + +Let it be supposed, that there is no other kind of causality than +that according to the laws of nature. Consequently, everything that +happens presupposes a previous condition, which it follows with +absolute certainty, in conformity with a rule. But this previous +condition must itself be something that has happened (that has +arisen in time, as it did not exist before), for, if it has always +been in existence, its consequence or effect would not thus +originate for the first time, but would likewise have always +existed. The causality, therefore, of a cause, whereby something +happens, is itself a thing that has happened. Now this again +presupposes, in conformity with the law of nature, a previous +condition and its causality, and this another anterior to the +former, and so on. If, then, everything happens solely in accordance +with the laws of nature, there cannot be any real first beginning of +things, but only a subaltern or comparative beginning. There cannot, +therefore, be a completeness of series on the side of the causes which +originate the one from the other. But the law of nature is that +nothing can happen without a sufficient a priori determined cause. +The proposition therefore--if all causality is possible only in accordance +with the laws of nature--is, when stated in this unlimited and general +manner, self-contradictory. It follows that this cannot be the only +kind of causality. + +From what has been said, it follows that a causality must be +admitted, by means of which something happens, without its cause being +determined according to necessary laws by some other cause +preceding. That is to say, there must exist an absolute spontaneity +of cause, which of itself originates a series of phenomena which proceeds +according to natural laws--consequently transcendental freedom, +without which even in the course of nature the succession of phenomena +on the side of causes is never complete. + + +ANTITHESIS. + +There is no such thing as freedom, but everything in the world +happens solely according to the laws of nature. + + +PROOF. + +Granted, that there does exist freedom in the transcendental +sense, as a peculiar kind of causality, operating to produce events +in the world--a faculty, that is to say, of originating a state, and +consequently a series of consequences from that state. In this case, +not only the series originated by this spontaneity, but the +determination of this spontaneity itself to the production of the +series, that is to say, the causality itself must have an absolute +commencement, such that nothing can precede to determine this action +according to unvarying laws. But every beginning of action presupposes +in the acting cause a state of inaction; and a dynamically primal +beginning of action presupposes a state, which has no connection--as +regards causality--with the preceding state of the cause--which does +not, that is, in any wise result from it. Transcendental freedom is +therefore opposed to the natural law of cause and effect, and such +a conjunction of successive states in effective causes is destructive +of the possibility of unity in experience and for that reason not to +be found in experience--is consequently a mere fiction of thought. + +We have, therefore, nothing but nature to which we must look for +connection and order in cosmical events. Freedom--independence of +the laws of nature--is certainly a deliverance from restraint, but +it is also a relinquishing of the guidance of law and rule. For it +cannot be alleged that, instead of the laws of nature, laws of freedom +may be introduced into the causality of the course of nature. For, +if freedom were determined according to laws, it would be no longer +freedom, but merely nature. Nature, therefore, and transcendental +freedom are distinguishable as conformity to law and lawlessness. +The former imposes upon understanding the difficulty of seeking the +origin of events ever higher and higher in the series of causes, +inasmuch as causality is always conditioned thereby; while it +compensates this labour by the guarantee of a unity complete and in +conformity with law. The latter, on the contrary, holds out to the +understanding the promise of a point of rest in the chain of causes, +by conducting it to an unconditioned causality, which professes to +have the power of spontaneous origination, but which, in its own utter +blindness, deprives it of the guidance of rules, by which alone a +completely connected experience is possible. + + + +OBSERVATIONS ON THE THIRD ANTINOMY. + +ON THE THESIS. + +The transcendental idea of freedom is far from constituting the +entire content of the psychological conception so termed, which is +for the most part empirical. It merely presents us with the conception +of spontaneity of action, as the proper ground for imputing freedom +to the cause of a certain class of objects. It is, however, the true +stumbling-stone to philosophy, which meets with unconquerable +difficulties in the way of its admitting this kind of unconditioned +causality. That element in the question of the freedom of the will, +which has for so long a time placed speculative reason in such +perplexity, is properly only transcendental, and concerns the +question, whether there must be held to exist a faculty of spontaneous +origination of a series of successive things or states. How such a +faculty is possible is not a necessary inquiry; for in the case of +natural causality itself, we are obliged to content ourselves with +the a priori knowledge that such a causality must be presupposed, although +we are quite incapable of comprehending how the being of one thing +is possible through the being of another, but must for this +information look entirely to experience. Now we have demonstrated this +necessity of a free first beginning of a series of phenomena, only +in so far as it is required for the comprehension of an origin of +the world, all following states being regarded as a succession +according to laws of nature alone. But, as there has thus been +proved the existence of a faculty which can of itself originate a +series in time--although we are unable to explain how it can exist--we +feel ourselves authorized to admit, even in the midst of the natural +course of events, a beginning, as regards causality, of different +successions of phenomena, and at the same time to attribute to all +substances a faculty of free action. But we ought in this case not +to allow ourselves to fall into a common misunderstanding, and to +suppose that, because a successive series in the world can only have +a comparatively first beginning--another state or condition of things +always preceding--an absolutely first beginning of a series in the +course of nature is impossible. For we are not speaking here of an +absolutely first beginning in relation to time, but as regards +causality alone. When, for example, I, completely of my own free will, +and independently of the necessarily determinative influence of +natural causes, rise from my chair, there commences with this event, +including its material consequences in infinitum, an absolutely new +series; although, in relation to time, this event is merely the +continuation of a preceding series. For this resolution and act of +mine do not form part of the succession of effects in nature, and +are not mere continuations of it; on the contrary, the determining +causes of nature cease to operate in reference to this event, which +certainly succeeds the acts of nature, but does not proceed from them. +For these reasons, the action of a free agent must be termed, in +regard to causality, if not in relation to time, an absolutely +primal beginning of a series of phenomena. + +The justification of this need of reason to rest upon a free act +as the first beginning of the series of natural causes is evident from +the fact, that all philosophers of antiquity (with the exception of +the Epicurean school) felt themselves obliged, when constructing a +theory of the motions of the universe, to accept a prime mover, that +is, a freely acting cause, which spontaneously and prior to all +other causes evolved this series of states. They always felt the +need of going beyond mere nature, for the purpose of making a first +beginning comprehensible. + + + +ON THE ANTITHESIS. + +The assertor of the all-sufficiency of nature in regard to causality +(transcendental Physiocracy), in opposition to the doctrine of +freedom, would defend his view of the question somewhat in the +following manner. He would say, in answer to the sophistical arguments +of the opposite party: If you do not accept a mathematical first, in +relation to time, you have no need to seek a dynamical first, in +regard to causality. Who compelled you to imagine an absolutely primal +condition of the world, and therewith an absolute beginning of the +gradually progressing successions of phenomena--and, as some +foundation for this fancy of yours, to set bounds to unlimited nature? +Inasmuch as the substances in the world have always existed--at +least the unity of experience renders such a supposition quite +necessary--there is no difficulty in believing also, that the +changes in the conditions of these substances have always existed; +and, consequently, that a first beginning, mathematical or +dynamical, is by no means required. The possibility of such an +infinite derivation, without any initial member from which all the +others result, is certainly quite incomprehensible. But, if you are +rash enough to deny the enigmatical secrets of nature for this reason, +you will find yourselves obliged to deny also the existence of many +fundamental properties of natural objects (such as fundamental +forces), which you can just as little comprehend; and even the +possibility of so simple a conception as that of change must present +to you insuperable difficulties. For if experience did not teach you +that it was real, you never could conceive a priori the possibility +of this ceaseless sequence of being and non-being. + +But if the existence of a transcendental faculty of freedom is +granted--a faculty of originating changes in the world--this faculty +must at least exist out of and apart from the world; although it is +certainly a bold assumption, that, over and above the complete content +of all possible intuitions, there still exists an object which +cannot be presented in any possible perception. But, to attribute to +substances in the world itself such a faculty, is quite +inadmissible; for, in this case; the connection of phenomena +reciprocally determining and determined according to general laws, +which is termed nature, and along with it the criteria of empirical +truth, which enable us to distinguish experience from mere visionary +dreaming, would almost entirely disappear. In proximity with such a +lawless faculty of freedom, a system of nature is hardly cogitable; +for the laws of the latter would be continually subject to the +intrusive influences of the former, and the course of phenomena, which +would otherwise proceed regularly and uniformly, would become +thereby confused and disconnected. + + + +FOURTH CONFLICT OF THE TRANSCENDENTAL IDEAS. + +THESIS. + +There exists either in, or in connection with the world--either as +a part of it, or as the cause of it--an absolutely necessary being. + + +PROOF. + +The world of sense, as the sum total of all phenomena, contains a +series of changes. For, without such a series, the mental +representation of the series of time itself, as the condition of the +possibility of the sensuous world, could not be presented to us.* +But every change stands under its condition, which precedes it in time +and renders it necessary. Now the existence of a given condition +presupposes a complete series of conditions up to the absolutely +unconditioned, which alone is absolutely necessary. It follows that +something that is absolutely necessary must exist, if change exists +as its consequence. But this necessary thing itself belongs to the +sensuous world. For suppose it to exist out of and apart from it, +the series of cosmical changes would receive from it a beginning, +and yet this necessary cause would not itself belong to the world of +sense. But this is impossible. For, as the beginning of a series in +time is determined only by that which precedes it in time, the supreme +condition of the beginning of a series of changes must exist in the +time in which this series itself did not exist; for a beginning +supposes a time preceding, in which the thing that begins to be was +not in existence. The causality of the necessary cause of changes, +and consequently the cause itself, must for these reasons belong to +time--and to phenomena, time being possible only as the form of +phenomena. Consequently, it cannot be cogitated as separated from +the world of sense--the sum total of all phenomena. There is, +therefore, contained in the world, something that is absolutely +necessary--whether it be the whole cosmical series itself, or only +a part of it. + +[*Footnote: Objectively, time, as the formal condition of the possibility +of change, precedes all changes; but subjectively, and in +consciousness, the representation of time, like every other, is +given solely by occasion of perception.] + + +ANTITHESIS. + +An absolutely necessary being does not exist, either in the world, +or out of it--as its cause. + + +PROOF. + +Grant that either the world itself is necessary, or that there is +contained in it a necessary existence. Two cases are possible. +First, there must either be in the series of cosmical changes a +beginning, which is unconditionally necessary, and therefore uncaused- +which is at variance with the dynamical law of the determination of +all phenomena in time; or, secondly, the series itself is without +beginning, and, although contingent and conditioned in all its +parts, is nevertheless absolutely necessary and unconditioned as a +whole--which is self-contradictory. For the existence of an +aggregate cannot be necessary, if no single part of it possesses +necessary existence. + +Grant, on the other band, that an absolutely necessary cause +exists out of and apart from the world. This cause, as the highest +member in the series of the causes of cosmical changes, must originate +or begin* the existence of the latter and their series. In this case +it must also begin to act, and its causality would therefore belong +to time, and consequently to the sum total of phenomena, that is, to +the world. It follows that the cause cannot be out of the world; which +is contradictory to the hypothesis. Therefore, neither in the world, +nor out of it (but in causal connection with it), does there exist +any absolutely necessary being. + +[*Footnote: The word begin is taken in two senses. The first is active-- +the cause being regarded as beginning a series of conditions as its +effect (infit). The second is passive--the causality in the cause itself +beginning to operate (fit). I reason here from the first to the second.] + + + +OBSERVATIONS ON THE FOURTH ANTINOMY. + +ON THE THESIS. + +To demonstrate the existence of a necessary being, I cannot be +permitted in this place to employ any other than the cosmological +argument, which ascends from the conditioned in phenomena to the +unconditioned in conception--the unconditioned being considered the +necessary condition of the absolute totality of the series. The proof, +from the mere idea of a supreme being, belongs to another principle +of reason and requires separate discussion. + +The pure cosmological proof demonstrates the existence of a +necessary being, but at the same time leaves it quite unsettled, +whether this being is the world itself, or quite distinct from it. +To establish the truth of the latter view, principles are requisite, +which are not cosmological and do not proceed in the series of +phenomena. We should require to introduce into our proof conceptions +of contingent beings--regarded merely as objects of the understanding, +and also a principle which enables us to connect these, by means of +mere conceptions, with a necessary being. But the proper place for +all such arguments is a transcendent philosophy, which has unhappily +not yet been established. + +But, if we begin our proof cosmologically, by laying at the +foundation of it the series of phenomena, and the regress in it +according to empirical laws of causality, we are not at liberty to +break off from this mode of demonstration and to pass over to +something which is not itself a member of the series. The condition +must be taken in exactly the same signification as the relation of +the conditioned to its condition in the series has been taken, for +the series must conduct us in an unbroken regress to this supreme +condition. But if this relation is sensuous, and belongs to the +possible empirical employment of understanding, the supreme +condition or cause must close the regressive series according to the +laws of sensibility and consequently, must belong to the series of +time. It follows that this necessary existence must be regarded as +the highest member of the cosmical series. + +Certain philosophers have, nevertheless, allowed themselves the +liberty of making such a saltus (metabasis eis allo gonos). From the +changes in the world they have concluded their empirical +contingency, that is, their dependence on empirically-determined +causes, and they thus admitted an ascending series of empirical +conditions: and in this they are quite right. But as they could not +find in this series any primal beginning or any highest member, they +passed suddenly from the empirical conception of contingency to the +pure category, which presents us with a series--not sensuous, but +intellectual--whose completeness does certainly rest upon the +existence of an absolutely necessary cause. Nay, more, this +intellectual series is not tied to any sensuous conditions; and is +therefore free from the condition of time, which requires it +spontaneously to begin its causality in time. But such a procedure +is perfectly inadmissible, as will be made plain from what follows. + +In the pure sense of the categories, that is contingent the +contradictory opposite of which is possible. Now we cannot reason from +empirical contingency to intellectual. The opposite of that which is +changed--the opposite of its state--is actual at another time, and +is therefore possible. Consequently, it is not the contradictory +opposite of the former state. To be that, it is necessary that, in +the same time in which the preceding state existed, its opposite could +have existed in its place; but such a cognition is not given us in +the mere phenomenon of change. A body that was in motion = A, comes +into a state of rest = non-A. Now it cannot be concluded from the fact +that a state opposite to the state A follows it, that the contradictory +opposite of A is possible; and that A is therefore contingent. To +prove this, we should require to know that the state of rest could +have existed in the very same time in which the motion took place. +Now we know nothing more than that the state of rest was actual in +the time that followed the state of motion; consequently, that it was +also possible. But motion at one time, and rest at another time, are +not contradictorily opposed to each other. It follows from what has +been said that the succession of opposite determinations, that is, +change, does not demonstrate the fact of contingency as represented +in the conceptions of the pure understanding; and that it cannot, +therefore, conduct us to the fact of the existence of a necessary +being. Change proves merely empirical contingency, that is to say, +that the new state could not have existed without a cause, which +belongs to the preceding time. This cause--even although it is +regarded as absolutely necessary--must be presented to us in time, +and must belong to the series of phenomena. + + +ON THE ANTITHESIS. + +The difficulties which meet us, in our attempt to rise through the +series of phenomena to the existence of an absolutely necessary +supreme cause, must not originate from our inability to establish +the truth of our mere conceptions of the necessary existence of a +thing. That is to say, our objections not be ontological, but must +be directed against the causal connection with a series of phenomena +of a condition which is itself unconditioned. In one word, they must +be cosmological and relate to empirical laws. We must show that the +regress in the series of causes (in the world of sense) cannot +conclude with an empirically unconditioned condition, and that the +cosmological argument from the contingency of the cosmical state--a +contingency alleged to arise from change--does not justify us in +accepting a first cause, that is, a prime originator of the cosmical +series. + +The reader will observe in this antinomy a very remarkable contrast. +The very same grounds of proof which established in the thesis the +existence of a supreme being, demonstrated in the antithesis--and with +equal strictness--the non-existence of such a being. We found, +first, that a necessary being exists, because the whole time past +contains the series of all conditions, and with it, therefore, the +unconditioned (the necessary); secondly, that there does not exist +any necessary being, for the same reason, that the whole time past +contains the series of all conditions--which are themselves, +therefore, in the aggregate, conditioned. The cause of this seeming +incongruity is as follows. We attend, in the first argument, solely +to the absolute totality of the series of conditions, the one of which +determines the other in time, and thus arrive at a necessary +unconditioned. In the second, we consider, on the contrary, the +contingency of everything that is determined in the series of time- +for every event is preceded by a time, in which the condition itself +must be determined as conditioned--and thus everything that is +unconditioned or absolutely necessary disappears. In both, the mode +of proof is quite in accordance with the common procedure of human +reason, which often falls into discord with itself, from considering +an object from two different points of view. Herr von Mairan +regarded the controversy between two celebrated astronomers, which +arose from a similar difficulty as to the choice of a proper +standpoint, as a phenomenon of sufficient importance to warrant a +separate treatise on the subject. The one concluded: the moon revolves +on its own axis, because it constantly presents the same side to the +earth; the other declared that the moon does not revolve on its own +axis, for the same reason. Both conclusions were perfectly correct, +according to the point of view from which the motions of the moon were +considered. + + + +SECTION III. Of the Interest of Reason in these Self-contradictions. + +We have thus completely before us the dialectical procedure of the +cosmological ideas. No possible experience can present us with an +object adequate to them in extent. Nay, more, reason itself cannot +cogitate them as according with the general laws of experience. And +yet they are not arbitrary fictions of thought. On the contrary, +reason, in its uninterrupted progress in the empirical synthesis, is +necessarily conducted to them, when it endeavours to free from all +conditions and to comprehend in its unconditioned totality that +which can only be determined conditionally in accordance with the laws +of experience. These dialectical propositions are so many attempts +to solve four natural and unavoidable problems of reason. There are +neither more, nor can there be less, than this number, because there +are no other series of synthetical hypotheses, limiting a priori the +empirical synthesis. + +The brilliant claims of reason striving to extend its dominion +beyond the limits of experience, have been represented above only in +dry formulae, which contain merely the grounds of its pretensions. +They have, besides, in conformity with the character of a +transcendental philosophy, been freed from every empirical element; +although the full splendour of the promises they hold out, and the +anticipations they excite, manifests itself only when in connection +with empirical cognitions. In the application of them, however, and +in the advancing enlargement of the employment of reason, while +struggling to rise from the region of experience and to soar to +those sublime ideas, philosophy discovers a value and a dignity, +which, if it could but make good its assertions, would raise it far +above all other departments of human knowledge--professing, as it +does, to present a sure foundation for our highest hopes and the +ultimate aims of all the exertions of reason. The questions: whether +the world has a beginning and a limit to its extension in space; +whether there exists anywhere, or perhaps, in my own thinking Self, +an indivisible and indestructible unity--or whether nothing but what +is divisible and transitory exists; whether I am a free agent, or, +like other beings, am bound in the chains of nature and fate; whether, +finally, there is a supreme cause of the world, or all our thought +and speculation must end with nature and the order of external things--are +questions for the solution of which the mathematician would +willingly exchange his whole science; for in it there is no +satisfaction for the highest aspirations and most ardent desires of +humanity. Nay, it may even be said that the true value of mathematics- +that pride of human reason--consists in this: that she guides reason +to the knowledge of nature--in her greater as well as in her less +manifestations--in her beautiful order and regularity--guides her, +moreover, to an insight into the wonderful unity of the moving +forces in the operations of nature, far beyond the expectations of +a philosophy building only on experience; and that she thus encourages +philosophy to extend the province of reason beyond all experience, +and at the same time provides it with the most excellent materials +for supporting its investigations, in so far as their nature admits, +by adequate and accordant intuitions. + +Unfortunately for speculation--but perhaps fortunately for the +practical interests of humanity--reason, in the midst of her highest +anticipations, finds herself hemmed in by a press of opposite and +contradictory conclusions, from which neither her honour nor her +safety will permit her to draw back. Nor can she regard these +conflicting trains of reasoning with indifference as mere passages +at arms, still less can she command peace; for in the subject of the +conflict she has a deep interest. There is no other course left open +to her than to reflect with herself upon the origin of this disunion +in reason--whether it may not arise from a mere misunderstanding. +After such an inquiry, arrogant claims would have to be given up on +both sides; but the sovereignty of reason over understanding and sense +would be based upon a sure foundation. + +We shall at present defer this radical inquiry and, in the meantime, +consider for a little what side in the controversy we should most +willingly take, if we were obliged to become partisans at all. As, +in this case, we leave out of sight altogether the logical criterion +of truth, and merely consult our own interest in reference to the +question, these considerations, although inadequate to settle the +question of right in either party, will enable us to comprehend how +those who have taken part in the struggle, adopt the one view rather +than the other--no special insight into the subject, however, having +influenced their choice. They will, at the same time, explain to us +many other things by the way--for example, the fiery zeal on the one +side and the cold maintenance of their cause on the other; why the +one party has met with the warmest approbations, and the other has +always been repulsed by irreconcilable prejudices. + +There is one thing, however, that determines the proper point of +view, from which alone this preliminary inquiry can be instituted +and carried on with the proper completeness--and that is the +comparison of the principles from which both sides, thesis and +antithesis, proceed. My readers would remark in the propositions of +the antithesis a complete uniformity in the mode of thought and a +perfect unity of principle. Its principle was that of pure empiricism, +not only in the explication of the phenomena in the world, but also +in the solution of the transcendental ideas, even of that of the universe +itself. The affirmations of the thesis, on the contrary, were based, +in addition to the empirical mode of explanation employed in the +series of phenomena, on intellectual propositions; and its +principles were in so far not simple. I shall term the thesis, in view +of its essential characteristic, the dogmatism of pure reason. + +On the side of Dogmatism, or of the thesis, therefore, in the +determination of the cosmological ideas, we find: + +1. A practical interest, which must be very dear to every +right-thinking man. That the word has a beginning--that the nature +of my thinking self is simple, and therefore indestructible--that I +am a free agent, and raised above the compulsion of nature and her +laws--and, finally, that the entire order of things, which form the +world, is dependent upon a Supreme Being, from whom the whole receives +unity and connection--these are so many foundation-stones of +morality and religion. The antithesis deprives us of all these +supports--or, at least, seems so to deprive us. + +2. A speculative interest of reason manifests itself on this side. +For, if we take the transcendental ideas and employ them in the manner +which the thesis directs, we can exhibit completely a priori the +entire chain of conditions, and understand the derivation of the +conditioned--beginning from the unconditioned. This the antithesis +does not do; and for this reason does not meet with so welcome a +reception. For it can give no answer to our question respecting the +conditions of its synthesis--except such as must be supplemented by +another question, and so on to infinity. According to it, we must rise +from a given beginning to one still higher; every part conducts us +to a still smaller one; every event is preceded by another event which +is its cause; and the conditions of existence rest always upon other +and still higher conditions, and find neither end nor basis in some +self-subsistent thing as the primal being. + +3. This side has also the advantage of popularity; and this +constitutes no small part of its claim to favour. The common +understanding does not find the least difficulty in the idea of the +unconditioned beginning of all synthesis--accustomed, as it is, rather +to follow our consequences than to seek for a proper basis for +cognition. In the conception of an absolute first, moreover--the +possibility of which it does not inquire into--it is highly +gratified to find a firmly-established point of departure for its +attempts at theory; while in the restless and continuous ascent from +the conditioned to the condition, always with one foot in the air, +it can find no satisfaction. + +On the side of the antithesis, or Empiricism, in the determination +of the cosmological ideas: + +1. We cannot discover any such practical interest arising from +pure principles of reason as morality and religion present. On the +contrary, pure empiricism seems to empty them of all their power and +influence. If there does not exist a Supreme Being distinct from the +world--if the world is without beginning, consequently without a +Creator--if our wills are not free, and the soul is divisible and +subject to corruption just like matter--the ideas and principles of +morality lose all validity and fall with the transcendental ideas +which constituted their theoretical support. + +2. But empiricism, in compensation, holds out to reason, in its +speculative interests, certain important advantages, far exceeding +any that the dogmatist can promise us. For, when employed by the +empiricist, understanding is always upon its proper ground of +investigation--the field of possible experience, the laws of which +it can explore, and thus extend its cognition securely and with +clear intelligence without being stopped by limits in any direction. +Here can it and ought it to find and present to intuition its proper +object--not only in itself, but in all its relations; or, if it employ +conceptions, upon this ground it can always present the +corresponding images in clear and unmistakable intuitions. It is quite +unnecessary for it to renounce the guidance of nature, to attach +itself to ideas, the objects of which it cannot know; because, as mere +intellectual entities, they cannot be presented in any intuition. On +the contrary, it is not even permitted to abandon its proper +occupation, under the pretence that it has been brought to a +conclusion (for it never can be), and to pass into the region of +idealizing reason and transcendent conceptions, which it is not +required to observe and explore the laws of nature, but merely to +think and to imagine--secure from being contradicted by facts, because +they have not been called as witnesses, but passed by, or perhaps +subordinated to the so-called higher interests and considerations of +pure reason. + +Hence the empiricist will never allow himself to accept any epoch of +nature for the first--the absolutely primal state; he will not believe +that there can be limits to his outlook into her wide domains, nor +pass from the objects of nature, which he can satisfactorily explain +by means of observation and mathematical thought--which he can +determine synthetically in intuition, to those which neither sense +nor imagination can ever present in concreto; he will not concede the +existence of a faculty in nature, operating independently of the +laws of nature--a concession which would introduce uncertainty into +the procedure of the understanding, which is guided by necessary +laws to the observation of phenomena; nor, finally, will he permit +himself to seek a cause beyond nature, inasmuch as we know nothing +but it, and from it alone receive an objective basis for all our +conceptions and instruction in the unvarying laws of things. + +In truth, if the empirical philosopher had no other purpose in the +establishment of his antithesis than to check the presumption of a +reason which mistakes its true destination, which boasts of its +insight and its knowledge, just where all insight and knowledge +cease to exist, and regards that which is valid only in relation to +a practical interest, as an advancement of the speculative interests +of the mind (in order, when it is convenient for itself, to break +the thread of our physical investigations, and, under pretence of +extending our cognition, connect them with transcendental ideas, by +means of which we really know only that we know nothing)--if, I say, +the empiricist rested satisfied with this benefit, the principle +advanced by him would be a maxim recommending moderation in the +pretensions of reason and modesty in its affirmations, and at the same +time would direct us to the right mode of extending the province of +the understanding, by the help of the only true teacher, experience. +In obedience to this advice, intellectual hypotheses and faith would +not be called in aid of our practical interests; nor should we +introduce them under the pompous titles of science and insight. For +speculative cognition cannot find an objective basis any other where +than in experience; and, when we overstep its limits our synthesis, +which requires ever new cognitions independent of experience, has no +substratum of intuition upon which to build. + +But if--as often happens--empiricism, in relation to ideas, +becomes itself dogmatic and boldly denies that which is above the +sphere of its phenomenal cognition, it falls itself into the error +of intemperance--an error which is here all the more reprehensible, +as thereby the practical interest of reason receives an irreparable +injury. + +And this constitutes the opposition between Epicureanism* and +Platonism. + +[*Footnote: It is, however, still a matter of doubt whether Epicurus +ever propounded these principles as directions for the objective employment +of the understanding. If, indeed, they were nothing more than maxims +for the speculative exercise of reason, he gives evidence therein a +more genuine philosophic spirit than any of the philosophers of +antiquity. That, in the explanation of phenomena, we must proceed as +if the field of inquiry had neither limits in space nor commencement +in time; that we must be satisfied with the teaching of experience +in reference to the material of which the world is posed; that we must +not look for any other mode of the origination of events than that +which is determined by the unalterable laws of nature; and finally, +that we not employ the hypothesis of a cause distinct from the world +to account for a phenomenon or for the world itself--are principles +for the extension of speculative philosophy, and the discovery of +the true sources of the principles of morals, which, however little +conformed to in the present day, are undoubtedly correct. At the +same time, any one desirous of ignoring, in mere speculation, these +dogmatical propositions, need not for that reason be accused of +denying them.] + +Both Epicurus and Plato assert more in their systems than they know. +The former encourages and advances science--although to the +prejudice of the practical; the latter presents us with excellent +principles for the investigation of the practical, but, in relation +to everything regarding which we can attain to speculative cognition, +permits reason to append idealistic explanations of natural phenomena, +to the great injury of physical investigation. + +3. In regard to the third motive for the preliminary choice of a +party in this war of assertions, it seems very extraordinary that +empiricism should be utterly unpopular. We should be inclined to +believe that the common understanding would receive it with +pleasure--promising as it does to satisfy it without passing the +bounds of experience and its connected order; while transcendental +dogmatism obliges it to rise to conceptions which far surpass the +intelligence and ability of the most practised thinkers. But in +this, in truth, is to be found its real motive. For the common +understanding thus finds itself in a situation where not even the most +learned can have the advantage of it. If it understands little or +nothing about these transcendental conceptions, no one can boast of +understanding any more; and although it may not express itself in so +scholastically correct a manner as others, it can busy itself with +reasoning and arguments without end, wandering among mere ideas, about +which one can always be very eloquent, because we know nothing about +them; while, in the observation and investigation of nature, it +would be forced to remain dumb and to confess its utter ignorance. +Thus indolence and vanity form of themselves strong recommendations +of these principles. Besides, although it is a hard thing for a +philosopher to assume a principle, of which he can give to himself +no reasonable account, and still more to employ conceptions, the +objective reality of which cannot be established, nothing is more +usual with the common understanding. It wants something which will +allow it to go to work with confidence. The difficulty of even +comprehending a supposition does not disquiet it, because--not knowing +what comprehending means--it never even thinks of the supposition it +may be adopting as a principle; and regards as known that with which +it has become familiar from constant use. And, at last, all +speculative interests disappear before the practical interests which +it holds dear; and it fancies that it understands and knows what its +necessities and hopes incite it to assume or to believe. Thus the +empiricism of transcendentally idealizing reason is robbed of all +popularity; and, however prejudicial it may be to the highest +practical principles, there is no fear that it will ever pass the +limits of the schools, or acquire any favour or influence in society +or with the multitude. + +Human reason is by nature architectonic. That is to say, it +regards all cognitions as parts of a possible system, and hence +accepts only such principles as at least do not incapacitate a +cognition to which we may have attained from being placed along with +others in a general system. But the propositions of the antithesis +are of a character which renders the completion of an edifice of +cognitions impossible. According to these, beyond one state or epoch +of the world there is always to be found one more ancient; in every +part always other parts themselves divisible; preceding every event +another, the origin of which must itself be sought still higher; and +everything in existence is conditioned, and still not dependent on +an unconditioned and primal existence. As, therefore, the antithesis +will not concede the existence of a first beginning which might be +available as a foundation, a complete edifice of cognition, in the +presence of such hypothesis, is utterly impossible. Thus the +architectonic interest of reason, which requires a unity--not +empirical, but a priori and rational--forms a natural recommendation +for the assertions of the thesis in our antinomy. + +But if any one could free himself entirely from all considerations +of interest, and weigh without partiality the assertions of reason, +attending only to their content, irrespective of the consequences +which follow from them; such a person, on the supposition that he knew +no other way out of the confusion than to settle the truth of one or +other of the conflicting doctrines, would live in a state of continual +hesitation. Today, he would feel convinced that the human will is +free; to-morrow, considering the indissoluble chain of nature, he +would look on freedom as a mere illusion and declare nature to be +all-in-all. But, if he were called to action, the play of the merely +speculative reason would disappear like the shapes of a dream, and +practical interest would dictate his choice of principles. But, as +it well befits a reflective and inquiring being to devote certain +periods of time to the examination of its own reason--to divest itself +of all partiality, and frankly to communicate its observations for +the judgement and opinion of others; so no one can be blamed for, much +less prevented from, placing both parties on their trial, with +permission to end themselves, free from intimidation, before +intimidation, before a sworn jury of equal condition with +themselves--the condition of weak and fallible men. + + + +SECTION IV. Of the necessity imposed upon Pure Reason of + presenting a Solution of its Transcendental Problems. + +To avow an ability to solve all problems and to answer all questions +would be a profession certain to convict any philosopher of +extravagant boasting and self-conceit, and at once to destroy the +confidence that might otherwise have been reposed in him. There are, +however, sciences so constituted that every question arising within +their sphere must necessarily be capable of receiving an answer from +the knowledge already possessed, for the answer must be received +from the same sources whence the question arose. In such sciences it +is not allowable to excuse ourselves on the plea of necessary and +unavoidable ignorance; a solution is absolutely requisite. The rule +of right and wrong must help us to the knowledge of what is right or +wrong in all possible cases; otherwise, the idea of obligation or duty +would be utterly null, for we cannot have any obligation to that which +we cannot know. On the other hand, in our investigations of the +phenomena of nature, much must remain uncertain, and many questions +continue insoluble; because what we know of nature is far from being +sufficient to explain all the phenomena that are presented to our +observation. Now the question is: Whether there is in +transcendental philosophy any question, relating to an object +presented to pure reason, which is unanswerable by this reason; and +whether we must regard the subject of the question as quite uncertain, +so far as our knowledge extends, and must give it a place among +those subjects, of which we have just so much conception as is +sufficient to enable us to raise a question--faculty or materials +failing us, however, when we attempt an answer. + +Now I maintain that, among all speculative cognition, the +peculiarity of transcendental philosophy is that there is no question, +relating to an object presented to pure reason, which is insoluble +by this reason; and that the profession of unavoidable ignorance- +the problem being alleged to be beyond the reach of our faculties- +cannot free us from the obligation to present a complete and +satisfactory answer. For the very conception which enables us to raise +the question must give us the power of answering it; inasmuch as the +object, as in the case of right and wrong, is not to be discovered +out of the conception. + +But, in transcendental philosophy, it is only the cosmological +questions to which we can demand a satisfactory answer in relation +to the constitution of their object; and the philosopher is not +permitted to avail himself of the pretext of necessary ignorance and +impenetrable obscurity. These questions relate solely to the +cosmological ideas. For the object must be given in experience, and +the question relates to the adequateness of the object to an idea. +If the object is transcendental and therefore itself unknown; if the +question, for example, is whether the object--the something, the +phenomenon of which (internal--in ourselves) is thought--that is to +say, the soul, is in itself a simple being; or whether there is a +cause of all things, which is absolutely necessary--in such cases we +are seeking for our idea an object, of which we may confess that it +is unknown to us, though we must not on that account assert that it +is impossible.* The cosmological ideas alone posses the peculiarity +that we can presuppose the object of them and the empirical +synthesis requisite for the conception of that object to be given; +and the question, which arises from these ideas, relates merely to +the progress of this synthesis, in so far as it must contain absolute +totality--which, however, is not empirical, as it cannot be given in +any experience. Now, as the question here is solely in regard to a +thing as the object of a possible experience and not as a thing in +itself, the answer to the transcendental cosmological question need +not be sought out of the idea, for the question does not regard an +object in itself. The question in relation to a possible experience +is not, "What can be given in an experience in concreto" but "what +is contained in the idea, to which the empirical synthesis must +approximate." The question must therefore be capable of solution +from the idea alone. For the idea is a creation of reason itself, +which therefore cannot disclaim the obligation to answer or refer us +to the unknown object. + +[*Footnote: The question, "What is the constitution of a transcendental +object?" is unanswerable--we are unable to say what it is; but we +can perceive that the question itself is nothing; because it does +not relate to any object that can be presented to us. For this reason, +we must consider all the questions raised in transcendental psychology +as answerable and as really answered; for they relate to the +transcendental subject of all internal phenomena, which is not +itself phenomenon and consequently not given as an object, in which, +moreover, none of the categories--and it is to them that the +question is properly directed--find any conditions of its application. +Here, therefore, is a case where no answer is the only proper +answer. For a question regarding the constitution of a something which +cannot be cogitated by any determined predicate, being completely +beyond the sphere of objects and experience, is perfectly null and +void.] + +It is not so extraordinary, as it at first sight appears, that a +science should demand and expect satisfactory answers to all the +questions that may arise within its own sphere (questiones +domesticae), although, up to a certain time, these answers may not +have been discovered. There are, in addition to transcendental +philosophy, only two pure sciences of reason; the one with a +speculative, the other with a practical content--pure mathematics +and pure ethics. Has any one ever heard it alleged that, from our +complete and necessary ignorance of the conditions, it is uncertain +what exact relation the diameter of a circle bears to the circle in +rational or irrational numbers? By the former the sum cannot be +given exactly, by the latter only approximately; and therefore we +decide that the impossibility of a solution of the question is +evident. Lambert presented us with a demonstration of this. In the +general principles of morals there can be nothing uncertain, for the +propositions are either utterly without meaning, or must originate +solely in our rational conceptions. On the other hand, there must be +in physical science an infinite number of conjectures, which can never +become certainties; because the phenomena of nature are not given as +objects dependent on our conceptions. The key to the solution of +such questions cannot, therefore, be found in our conceptions, or in +pure thought, but must lie without us and for that reason is in many +cases not to be discovered; and consequently a satisfactory +explanation cannot be expected. The questions of transcendental +analytic, which relate to the deduction of our pure cognition, are +not to be regarded as of the same kind as those mentioned above; for +we are not at present treating of the certainty of judgements in relation +to the origin of our conceptions, but only of that certainty in +relation to objects. + +We cannot, therefore, escape the responsibility of at least a +critical solution of the questions of reason, by complaints of the +limited nature of our faculties, and the seemingly humble confession +that it is beyond the power of our reason to decide, whether the world +has existed from all eternity or had a beginning--whether it is +infinitely extended, or enclosed within certain limits--whether +anything in the world is simple, or whether everything must be capable +of infinite divisibility--whether freedom can originate phenomena, +or whether everything is absolutely dependent on the laws and order +of nature--and, finally, whether there exists a being that is +completely unconditioned and necessary, or whether the existence of +everything is conditioned and consequently dependent on something +external to itself, and therefore in its own nature contingent. For +all these questions relate to an object, which can be given nowhere +else than in thought. This object is the absolutely unconditioned +totality of the synthesis of phenomena. If the conceptions in our +minds do not assist us to some certain result in regard to these +problems, we must not defend ourselves on the plea that the object +itself remains hidden from and unknown to us. For no such thing or +object can be given--it is not to be found out of the idea in our +minds. We must seek the cause of our failure in our idea itself, which +is an insoluble problem and in regard to which we obstinately assume +that there exists a real object corresponding and adequate to it. A +clear explanation of the dialectic which lies in our conception, +will very soon enable us to come to a satisfactory decision in +regard to such a question. + +The pretext that we are unable to arrive at certainty in regard to +these problems may be met with this question, which requires at +least a plain answer: "From what source do the ideas originate, the +solution of which involves you in such difficulties? Are you seeking +for an explanation of certain phenomena; and do you expect these ideas +to give you the principles or the rules of this explanation?" Let it +be granted, that all nature was laid open before you; that nothing +was hid from your senses and your consciousness. Still, you could not +cognize in concreto the object of your ideas in any experience. For +what is demanded is not only this full and complete intuition, but +also a complete synthesis and the consciousness of its absolute +totality; and this is not possible by means of any empirical +cognition. It follows that your question--your idea--is by no means +necessary for the explanation of any phenomenon; and the idea cannot +have been in any sense given by the object itself. For such an +object can never be presented to us, because it cannot be given by +any possible experience. Whatever perceptions you may attain to, you +are still surrounded by conditions--in space, or in time--and you cannot +discover anything unconditioned; nor can you decide whether this +unconditioned is to be placed in an absolute beginning of the +synthesis, or in an absolute totality of the series without beginning. +A whole, in the empirical signification of the term, is always +merely comparative. The absolute whole of quantity (the universe), +of division, of derivation, of the condition of existence, with the +question--whether it is to be produced by finite or infinite +synthesis, no possible experience can instruct us concerning. You will +not, for example, be able to explain the phenomena of a body in the +least degree better, whether you believe it to consist of simple, or +of composite parts; for a simple phenomenon--and just as little an +infinite series of composition--can never be presented to your +perception. Phenomena require and admit of explanation, only in so +far as the conditions of that explanation are given in perception; +but the sum total of that which is given in phenomena, considered as +an absolute whole, is itself a perception--and we cannot therefore +seek for explanations of this whole beyond itself, in other perceptions. +The explanation of this whole is the proper object of the +transcendental problems of pure reason. + +Although, therefore, the solution of these problems is +unattainable through experience, we must not permit ourselves to say +that it is uncertain how the object of our inquiries is constituted. +For the object is in our own mind and cannot be discovered in +experience; and we have only to take care that our thoughts are +consistent with each other, and to avoid falling into the amphiboly +of regarding our idea as a representation of an object empirically +given, and therefore to be cognized according to the laws of experience. +A dogmatical solution is therefore not only unsatisfactory but +impossible. The critical solution, which may be a perfectly certain +one, does not consider the question objectively, but proceeds by +inquiring into the basis of the cognition upon which the question +rests. + + + +SECTION V. Sceptical Exposition of the Cosmological Problems + presented in the four Transcendental Ideas. + +We should be quite willing to desist from the demand of a dogmatical +answer to our questions, if we understood beforehand that, be the +answer what it may, it would only serve to increase our ignorance, +to throw us from one incomprehensibility into another, from one +obscurity into another still greater, and perhaps lead us into +irreconcilable contradictions. If a dogmatical affirmative or negative +answer is demanded, is it at all prudent to set aside the probable +grounds of a solution which lie before us and to take into +consideration what advantage we shall gain, if the answer is to favour +the one side or the other? If it happens that in both cases the answer +is mere nonsense, we have in this an irresistible summons to institute +a critical investigation of the question, for the purpose of +discovering whether it is based on a groundless presupposition and +relates to an idea, the falsity of which would be more easily +exposed in its application and consequences than in the mere +representation of its content. This is the great utility of the +sceptical mode of treating the questions addressed by pure reason to +itself. By this method we easily rid ourselves of the confusions of +dogmatism, and establish in its place a temperate criticism, which, +as a genuine cathartic, will successfully remove the presumptuous notions +of philosophy and their consequence--the vain pretension to +universal science. + +If, then, I could understand the nature of a cosmological idea and +perceive, before I entered on the discussion of the subject at all, +that, whatever side of the question regarding the unconditioned of +the regressive synthesis of phenomena it favoured--it must either be +too great or too small for every conception of the understanding--I +would be able to comprehend how the idea, which relates to an object +of experience--an experience which must be adequate to and in +accordance with a possible conception of the understanding--must be +completely void and without significance, inasmuch as its object is +inadequate, consider it as we may. And this is actually the case +with all cosmological conceptions, which, for the reason above +mentioned, involve reason, so long as it remains attached to them, +in an unavoidable antinomy. For suppose: + +First, that the world has no beginning--in this case it is too large +for our conception; for this conception, which consists in a +successive regress, cannot overtake the whole eternity that has +elapsed. Grant that it has a beginning, it is then too small for the +conception of the understanding. For, as a beginning presupposes a +time preceding, it cannot be unconditioned; and the law of the +empirical employment of the understanding imposes the necessity of +looking for a higher condition of time; and the world is, therefore, +evidently too small for this law. + +The same is the case with the double answer to the question +regarding the extent, in space, of the world. For, if it is infinite +and unlimited, it must be too large for every possible empirical +conception. If it is finite and limited, we have a right to ask: "What +determines these limits?" Void space is not a self-subsistent +correlate of things, and cannot be a final condition--and still less +an empirical condition, forming a part of a possible experience. For +how can we have any experience or perception of an absolute void? +But the absolute totality of the empirical synthesis requires that +the unconditioned be an empirical conception. Consequently, a finite +world is too small for our conception. + +Secondly, if every phenomenon (matter) in space consists of an +infinite number of parts, the regress of the division is always too +great for our conception; and if the division of space must cease with +some member of the division (the simple), it is too small for the idea +of the unconditioned. For the member at which we have discontinued +our division still admits a regress to many more parts contained in +the object. + +Thirdly, suppose that every event in the world happens in accordance +with the laws of nature; the causality of a cause must itself be an +event and necessitates a regress to a still higher cause, and +consequently the unceasing prolongation of the series of conditions +a parte priori. Operative nature is therefore too large for every +conception we can form in the synthesis of cosmical events. + +If we admit the existence of spontaneously produced events, that is, +of free agency, we are driven, in our search for sufficient reasons, +on an unavoidable law of nature and are compelled to appeal to the +empirical law of causality, and we find that any such totality of +connection in our synthesis is too small for our necessary empirical +conception. + +Fourthly, if we assume the existence of an absolutely necessary +being--whether it be the world or something in the world, or the cause +of the world--we must place it in a time at an infinite distance +from any given moment; for, otherwise, it must be dependent on some +other and higher existence. Such an existence is, in this case, too +large for our empirical conception, and unattainable by the +continued regress of any synthesis. + +But if we believe that everything in the world--be it condition or +conditioned--is contingent; every given existence is too small for +our conception. For in this case we are compelled to seek for some +other existence upon which the former depends. + +We have said that in all these cases the cosmological idea is either +too great or too small for the empirical regress in a synthesis, and +consequently for every possible conception of the understanding. Why +did we not express ourselves in a manner exactly the reverse of this +and, instead of accusing the cosmological idea of over stepping or +of falling short of its true aim, possible experience, say that, in +the first case, the empirical conception is always too small for the +idea, and in the second too great, and thus attach the blame of +these contradictions to the empirical regress? The reason is this. +Possible experience can alone give reality to our conceptions; without +it a conception is merely an idea, without truth or relation to an +object. Hence a possible empirical conception must be the standard +by which we are to judge whether an idea is anything more than an idea +and fiction of thought, or whether it relates to an object in the +world. If we say of a thing that in relation to some other thing it +is too large or too small, the former is considered as existing for +the sake of the latter, and requiring to be adapted to it. Among the +trivial subjects of discussion in the old schools of dialectics was +this question: "If a ball cannot pass through a hole, shall we say +that the ball is too large or the hole too small?" In this case it +is indifferent what expression we employ; for we do not know which +exists for the sake of the other. On the other hand, we cannot say: +"The man is too long for his coat"; but: "The coat is too short for +the man." + +We are thus led to the well-founded suspicion that the +cosmological ideas, and all the conflicting sophistical assertions +connected with them, are based upon a false and fictitious +conception of the mode in which the object of these ideas is presented +to us; and this suspicion will probably direct us how to expose the +illusion that has so long led us astray from the truth. + + + +SECTION VI. Transcendental Idealism as the Key to the + Solution of Pure Cosmological Dialectic. + +In the transcendental aesthetic we proved that everything intuited +in space and time, all objects of a possible experience, are nothing +but phenomena, that is, mere representations; and that these, as +presented to us--as extended bodies, or as series of changes--have +no self-subsistent existence apart from human thought. This doctrine +I call Transcendental Idealism.* The realist in the transcendental +sense regards these modifications of our sensibility, these mere +representations, as things subsisting in themselves. + +[*Footnote: I have elsewhere termed this theory formal idealism, to +distinguish it from material idealism, which doubts or denies the +existence of external things. To avoid ambiguity, it seems advisable +in many cases to employ this term instead of that mentioned in the text.] + +It would be unjust to accuse us of holding the long-decried theory +of empirical idealism, which, while admitting the reality of space, +denies, or at least doubts, the existence of bodies extended in it, +and thus leaves us without a sufficient criterion of reality and +illusion. The supporters of this theory find no difficulty in +admitting the reality of the phenomena of the internal sense in +time; nay, they go the length of maintaining that this internal +experience is of itself a sufficient proof of the real existence of +its object as a thing in itself. + +Transcendental idealism allows that the objects of external +intuition--as intuited in space, and all changes in time--as +represented by the internal sense, are real. For, as space is the form +of that intuition which we call external, and, without objects in +space, no empirical representation could be given us, we can and ought +to regard extended bodies in it as real. The case is the same with +representations in time. But time and space, with all phenomena +therein, are not in themselves things. They are nothing but +representations and cannot exist out of and apart from the mind. +Nay, the sensuous internal intuition of the mind (as the object of +consciousness), the determination of which is represented by the +succession of different states in time, is not the real, proper +self, as it exists in itself--not the transcendental subject--but only +a phenomenon, which is presented to the sensibility of this, to us, +unknown being. This internal phenomenon cannot be admitted to be a +self-subsisting thing; for its condition is time, and time cannot be +the condition of a thing in itself. But the empirical truth of +phenomena in space and time is guaranteed beyond the possibility of +doubt, and sufficiently distinguished from the illusion of dreams or +fancy--although both have a proper and thorough connection in an +experience according to empirical laws. The objects of experience then +are not things in themselves, but are given only in experience, and +have no existence apart from and independently of experience. That +there may be inhabitants in the moon, although no one has ever +observed them, must certainly be admitted; but this assertion means +only, that we may in the possible progress of experience discover them +at some future time. For that which stands in connection with a +perception according to the laws of the progress of experience is +real. They are therefore really existent, if they stand in empirical +connection with my actual or real consciousness, although they are +not in themselves real, that is, apart from the progress of experience. + +There is nothing actually given--we can be conscious of nothing as +real, except a perception and the empirical progression from it to +other possible perceptions. For phenomena, as mere representations, +are real only in perception; and perception is, in fact, nothing but +the reality of an empirical representation, that is, a phenomenon. +To call a phenomenon a real thing prior to perception means either +that we must meet with this phenomenon in the progress of +experience, or it means nothing at all. For I can say only of a +thing in itself that it exists without relation to the senses and +experience. But we are speaking here merely of phenomena in space +and time, both of which are determinations of sensibility, and not +of things in themselves. It follows that phenomena are not things in +themselves, but are mere representations, which if not given in us--in +perception--are non-existent. + +The faculty of sensuous intuition is properly a receptivity--a +capacity of being affected in a certain manner by representations, +the relation of which to each other is a pure intuition of space and +time--the pure forms of sensibility. These representations, in so far +as they are connected and determinable in this relation (in space and +time) according to laws of the unity of experience, are called +objects. The non-sensuous cause of these representations is completely +unknown to us and hence cannot be intuited as an object. For such an +object could not be represented either in space or in time; and +without these conditions intuition or representation is impossible. +We may, at the same time, term the non-sensuous cause of phenomena +the transcendental object--but merely as a mental correlate to +sensibility, considered as a receptivity. To this transcendental +object we may attribute the whole connection and extent of our +possible perceptions, and say that it is given and exists in itself +prior to all experience. But the phenomena, corresponding to it, are +not given as things in themselves, but in experience alone. For they +are mere representations, receiving from perceptions alone +significance and relation to a real object, under the condition that +this or that perception--indicating an object--is in complete +connection with all others in accordance with the rules of the unity +of experience. Thus we can say: "The things that really existed in +past time are given in the transcendental object of experience." But +these are to me real objects, only in so far as I can represent to +my own mind, that a regressive series of possible perceptions- +following the indications of history, or the footsteps of cause and +effect--in accordance with empirical laws--that, in one word, the +course of the world conducts us to an elapsed series of time as the +condition of the present time. This series in past time is represented +as real, not in itself, but only in connection with a possible +experience. Thus, when I say that certain events occurred in past +time, I merely assert the possibility of prolonging the chain of +experience, from the present perception, upwards to the conditions +that determine it according to time. + +If I represent to myself all objects existing in all space and time, +I do not thereby place these in space and time prior to all +experience; on the contrary, such a representation is nothing more +than the notion of a possible experience, in its absolute +completeness. In experience alone are those objects, which are nothing +but representations, given. But, when I say they existed prior to my +experience, this means only that I must begin with the perception +present to me and follow the track indicated until I discover them +in some part or region of experience. The cause of the empirical +condition of this progression--and consequently at what member therein +I must stop, and at what point in the regress I am to find this +member--is transcendental, and hence necessarily incognizable. But +with this we have not to do; our concern is only with the law of +progression in experience, in which objects, that is, phenomena, are +given. It is a matter of indifference, whether I say, "I may in the +progress of experience discover stars, at a hundred times greater +distance than the most distant of those now visible," or, "Stars at +this distance may be met in space, although no one has, or ever will +discover them." For, if they are given as things in themselves, +without any relation to possible experience, they are for me +non-existent, consequently, are not objects, for they are not +contained in the regressive series of experience. But, if these +phenomena must be employed in the construction or support of the +cosmological idea of an absolute whole, and when we are discussing +a question that oversteps the limits of possible experience, the +proper distinction of the different theories of the reality of +sensuous objects is of great importance, in order to avoid the +illusion which must necessarily arise from the misinterpretation of +our empirical conceptions. + + + +SECTION VII. Critical Solution of the Cosmological Problem. + +The antinomy of pure reason is based upon the following +dialectical argument: "If that which is conditioned is given, the +whole series of its conditions is also given; but sensuous objects +are given as conditioned; consequently..." This syllogism, the major +of which seems so natural and evident, introduces as many cosmological +ideas as there are different kinds of conditions in the synthesis of +phenomena, in so far as these conditions constitute a series. These +ideas require absolute totality in the series, and thus place reason +in inextricable embarrassment. Before proceeding to expose the fallacy +in this dialectical argument, it will be necessary to have a correct +understanding of certain conceptions that appear in it. + +In the first place, the following proposition is evident, and +indubitably certain: "If the conditioned is given, a regress in the +series of all its conditions is thereby imperatively required." For +the very conception of a conditioned is a conception of something +related to a condition, and, if this condition is itself +conditioned, to another condition--and so on through all the members +of the series. This proposition is, therefore, analytical and has +nothing to fear from transcendental criticism. It is a logical +postulate of reason: to pursue, as far as possible, the connection +of a conception with its conditions. + +If, in the second place, both the conditioned and the condition +are things in themselves, and if the former is given, not only is +the regress to the latter requisite, but the latter is really given +with the former. Now, as this is true of all the members of the +series, the entire series of conditions, and with them the +unconditioned, is at the same time given in the very fact of the +conditioned, the existence of which is possible only in and through +that series, being given. In this case, the synthesis of the +conditioned with its condition, is a synthesis of the understanding +merely, which represents things as they are, without regarding whether +and how we can cognize them. But if I have to do with phenomena, +which, in their character of mere representations, are not given, if +I do not attain to a cognition of them (in other words, to themselves, +for they are nothing more than empirical cognitions), I am not +entitled to say: "If the conditioned is given, all its conditions +(as phenomena) are also given." I cannot, therefore, from the fact +of a conditioned being given, infer the absolute totality of the +series of its conditions. For phenomena are nothing but an empirical +synthesis in apprehension or perception, and are therefore given +only in it. Now, in speaking of phenomena it does not follow that, +if the conditioned is given, the synthesis which constitutes its +empirical condition is also thereby given and presupposed; such a +synthesis can be established only by an actual regress in the series +of conditions. But we are entitled to say in this case that a +regress to the conditions of a conditioned, in other words, that a +continuous empirical synthesis is enjoined; that, if the conditions +are not given, they are at least required; and that we are certain +to discover the conditions in this regress. + +We can now see that the major, in the above cosmological +syllogism, takes the conditioned in the transcendental signification +which it has in the pure category, while the minor speaks of it in +the empirical signification which it has in the category as applied +to phenomena. There is, therefore, a dialectical fallacy in the +syllogism--a sophisma figurae dictionis. But this fallacy is not a +consciously devised one, but a perfectly natural illusion of the +common reason of man. For, when a thing is given as conditioned, we +presuppose in the major its conditions and their series, +unperceived, as it were, and unseen; because this is nothing more than +the logical requirement of complete and satisfactory premisses for +a given conclusion. In this case, time is altogether left out in the +connection of the conditioned with the condition; they are supposed +to be given in themselves, and contemporaneously. It is, moreover, +just as natural to regard phenomena (in the minor) as things in +themselves and as objects presented to the pure understanding, as in +the major, in which complete abstraction was made of all conditions +of intuition. But it is under these conditions alone that objects are +given. Now we overlooked a remarkable distinction between the +conceptions. The synthesis of the conditioned with its condition, +and the complete series of the latter (in the major) are not limited +by time, and do not contain the conception of succession. On the +contrary, the empirical synthesis and the series of conditions in +the phenomenal world--subsumed in the minor--are necessarily +successive and given in time alone. It follows that I cannot +presuppose in the minor, as I did in the major, the absolute +totality of the synthesis and of the series therein represented; for +in the major all the members of the series are given as things in +themselves--without any limitations or conditions of time, while in +the minor they are possible only in and through a successive +regress, which cannot exist, except it be actually carried into +execution in the world of phenomena. + +After this proof of the viciousness of the argument commonly +employed in maintaining cosmological assertions, both parties may +now be justly dismissed, as advancing claims without grounds or title. +But the process has not been ended by convincing them that one or both +were in the wrong and had maintained an assertion which was without +valid grounds of proof. Nothing seems to be clearer than that, if +one maintains: "The world has a beginning," and another: "The world +has no beginning," one of the two must be right. But it is likewise +clear that, if the evidence on both sides is equal, it is impossible +to discover on what side the truth lies; and the controversy +continues, although the parties have been recommended to peace +before the tribunal of reason. There remains, then, no other means +of settling the question than to convince the parties, who refute each +other with such conclusiveness and ability, that they are disputing +about nothing, and that a transcendental illusion has been mocking +them with visions of reality where there is none. The mode of +adjusting a dispute which cannot be decided upon its own merits, we +shall now proceed to lay before our readers. + +Zeno of Elea, a subtle dialectician, was severely reprimanded by +Plato as a sophist, who, merely from the base motive of exhibiting +his skill in discussion, maintained and subverted the same proposition +by arguments as powerful and convincing on the one side as on the +other. He maintained, for example, that God (who was probably +nothing more, in his view, than the world) is neither finite nor +infinite, neither in motion nor in rest, neither similar nor +dissimilar to any other thing. It seemed to those philosophers who +criticized his mode of discussion that his purpose was to deny +completely both of two self-contradictory propositions--which is +absurd. But I cannot believe that there is any justice in this +accusation. The first of these propositions I shall presently consider +in a more detailed manner. With regard to the others, if by the word +of God he understood merely the Universe, his meaning must have +been--that it cannot be permanently present in one place--that is, +at rest--nor be capable of changing its place--that is, of moving- +because all places are in the universe, and the universe itself is, +therefore, in no place. Again, if the universe contains in itself +everything that exists, it cannot be similar or dissimilar to any +other thing, because there is, in fact, no other thing with which it +can be compared. If two opposite judgements presuppose a contingent +impossible, or arbitrary condition, both--in spite of their opposition +(which is, however, not properly or really a contradiction)--fall +away; because the condition, which ensured the validity of both, has +itself disappeared. + +If we say: "Everybody has either a good or a bad smell," we have +omitted a third possible judgement--it has no smell at all; and thus +both conflicting statements may be false. If we say: "It is either +good-smelling or not good-smelling (vel suaveolens vel +non-suaveolens)," both judgements are contradictorily opposed; and +the contradictory opposite of the former judgement--some bodies are +not good-smelling--embraces also those bodies which have no smell at +all. In the preceding pair of opposed judgements (per disparata), +the contingent condition of the conception of body (smell) attached +to both conflicting statements, instead of having been omitted in the +latter, which is consequently not the contradictory opposite of the +former. + +If, accordingly, we say: "The world is either infinite in extension, +or it is not infinite (non est infinitus)"; and if the former +proposition is false, its contradictory opposite--the world is not +infinite--must be true. And thus I should deny the existence of an +infinite, without, however affirming the existence of a finite +world. But if we construct our proposition thus: "The world is +either infinite or finite (non-infinite)," both statements may be +false. For, in this case, we consider the world as per se determined +in regard to quantity, and while, in the one judgement, we deny its +infinite and consequently, perhaps, its independent existence; in +the other, we append to the world, regarded as a thing in itself, a +certain determination--that of finitude; and the latter may be false +as well as the former, if the world is not given as a thing in itself, +and thus neither as finite nor as infinite in quantity. This kind of +opposition I may be allowed to term dialectical; that of +contradictories may be called analytical opposition. Thus then, of +two dialectically opposed judgements both may be false, from the fact, +that the one is not a mere contradictory of the other, but actually +enounces more than is requisite for a full and complete contradiction. + +When we regard the two propositions--"The world is infinite in +quantity," and, "The world is finite in quantity," as contradictory +opposites, we are assuming that the world--the complete series of +phenomena--is a thing in itself. For it remains as a permanent +quantity, whether I deny the infinite or the finite regress in the +series of its phenomena. But if we dismiss this assumption--this +transcendental illusion--and deny that it is a thing in itself, the +contradictory opposition is metamorphosed into a merely dialectical +one; and the world, as not existing in itself--independently of the +regressive series of my representations--exists in like manner neither +as a whole which is infinite nor as a whole which is finite in itself. +The universe exists for me only in the empirical regress of the series +of phenomena and not per se. If, then, it is always conditioned, it +is never completely or as a whole; and it is, therefore, not an +unconditioned whole and does not exist as such, either with an +infinite, or with a finite quantity. + +What we have here said of the first cosmological idea--that of the +absolute totality of quantity in phenomena--applies also to the +others. The series of conditions is discoverable only in the +regressive synthesis itself, and not in the phenomenon considered as +a thing in itself--given prior to all regress. Hence I am compelled +to say: "The aggregate of parts in a given phenomenon is in itself +neither finite nor infinite; and these parts are given only in the +regressive synthesis of decomposition--a synthesis which is never +given in absolute completeness, either as finite, or as infinite." +The same is the case with the series of subordinated causes, or of +the conditioned up to the unconditioned and necessary existence, which +can never be regarded as in itself, ind in its totality, either as +finite or as infinite; because, as a series of subordinate +representations, it subsists only in the dynamical regress and +cannot be regarded as existing previously to this regress, or as a +self-subsistent series of things. + +Thus the antinomy of pure reason in its cosmological ideas +disappears. For the above demonstration has established the fact +that it is merely the product of a dialectical and illusory +opposition, which arises from the application of the idea of +absolute totality--admissible only as a condition of things in +themselves--to phenomena, which exist only in our representations, +and--when constituting a series--in a successive regress. This +antinomy of reason may, however, be really profitable to our +speculative interests, not in the way of contributing any dogmatical +addition, but as presenting to us another material support in our +critical investigations. For it furnishes us with an indirect proof +of the transcendental ideality of phenomena, if our minds were not +completely satisfied with the direct proof set forth in the +Trancendental Aesthetic. The proof would proceed in the following +dilemma. If the world is a whole existing in itself, it must be either +finite or infinite. But it is neither finite nor infinite--as has been +shown, on the one side, by the thesis, on the other, by the +antithesis. Therefore the world--the content of all phenomena--is +not a whole existing in itself. It follows that phenomena are nothing, +apart from our representations. And this is what we mean by +transcendental ideality. + +This remark is of some importance. It enables us to see that the +proofs of the fourfold antinomy are not mere sophistries--are not +fallacious, but grounded on the nature of reason, and valid--under +the supposition that phenomena are things in themselves. The opposition +of the judgements which follow makes it evident that a fallacy lay +in the initial supposition, and thus helps us to discover the true +constitution of objects of sense. This transcendental dialectic does +not favour scepticism, although it presents us with a triumphant +demonstration of the advantages of the sceptical method, the great +utility of which is apparent in the antinomy, where the arguments of +reason were allowed to confront each other in undiminished force. +And although the result of these conflicts of reason is not what we +expected--although we have obtained no positive dogmatical addition +to metaphysical science--we have still reaped a great advantage in +the correction of our judgements on these subjects of thought. + + + +SECTION VIII. Regulative Principle of Pure Reason in relation + to the Cosmological Ideas. + +The cosmological principle of totality could not give us any certain +knowledge in regard to the maximum in the series of conditions in +the world of sense, considered as a thing in itself. The actual +regress in the series is the only means of approaching this maximum. +This principle of pure reason, therefore, may still be considered as +valid--not as an axiom enabling us to cogitate totality in the +object as actual, but as a problem for the understanding, which +requires it to institute and to continue, in conformity with the +idea of totality in the mind, the regress in the series of the +conditions of a given conditioned. For in the world of sense, that +is, in space and time, every condition which we discover in our +investigation of phenomena is itself conditioned; because sensuous +objects are not things in themselves (in which case an absolutely +unconditioned might be reached in the progress of cognition), but +are merely empirical representations the conditions of which must +always be found in intuition. The principle of reason is therefore +properly a mere rule--prescribing a regress in the series of +conditions for given phenomena, and prohibiting any pause or rest on +an absolutely unconditioned. It is, therefore, not a principle of +the possibility of experience or of the empirical cognition of +sensuous objects--consequently not a principle of the understanding; +for every experience is confined within certain proper limits +determined by the given intuition. Still less is it a constitutive +principle of reason authorizing us to extend our conception of the +sensuous world beyond all possible experience. It is merely a +principle for the enlargement and extension of experience as far as +is possible for human faculties. It forbids us to consider any +empirical limits as absolute. It is, hence, a principle of reason, +which, as a rule, dictates how we ought to proceed in our empirical +regress, but is unable to anticipate or indicate prior to the +empirical regress what is given in the object itself. I have termed +it for this reason a regulative principle of reason; while the +principle of the absolute totality of the series of conditions, as +existing in itself and given in the object, is a constitutive +cosmological principle. This distinction will at once demonstrate +the falsehood of the constitutive principle, and prevent us from +attributing (by a transcendental subreptio) objective reality to an +idea, which is valid only as a rule. + +In order to understand the proper meaning of this rule of pure +reason, we must notice first that it cannot tell us what the object +is, but only how the empirical regress is to be proceeded with in +order to attain to the complete conception of the object. If it gave +us any information in respect to the former statement, it would be +a constitutive principle--a principle impossible from the nature of +pure reason. It will not therefore enable us to establish any such +conclusions as: "The series of conditions for a given conditioned is +in itself finite," or, "It is infinite." For, in this case, we +should be cogitating in the mere idea of absolute totality, an +object which is not and cannot be given in experience; inasmuch as +we should be attributing a reality objective and independent of the +empirical synthesis, to a series of phenomena. This idea of reason +cannot then be regarded as valid--except as a rule for the +regressive synthesis in the series of conditions, according to which +we must proceed from the conditioned, through all intermediate and +subordinate conditions, up to the unconditioned; although this goal +is unattained and unattainable. For the absolutely unconditioned cannot +be discovered in the sphere of experience. + +We now proceed to determine clearly our notion of a synthesis +which can never be complete. There are two terms commonly employed +for this purpose. These terms are regarded as expressions of different +and distinguishable notions, although the ground of the distinction +has never been clearly exposed. The term employed by the mathematicians +is progressus in infinitum. The philosophers prefer the expression +progressus in indefinitum. Without detaining the reader with an +examination of the reasons for such a distinction, or with remarks +on the right or wrong use of the terms, I shall endeavour clearly to +determine these conceptions, so far as is necessary for the purpose +in this Critique. + +We may, with propriety, say of a straight line, that it may be +produced to infinity. In this case the distinction between a +progressus in infinitum and a progressus in indefinitum is a mere +piece of subtlety. For, although when we say, "Produce a straight +line," it is more correct to say in indefinitum than in infinitum; +because the former means, "Produce it as far as you please," the +second, "You must not cease to produce it"; the expression in +infinitum is, when we are speaking of the power to do it, perfectly +correct, for we can always make it longer if we please--on to +infinity. And this remark holds good in all cases, when we speak of +a progressus, that is, an advancement from the condition to the +conditioned; this possible advancement always proceeds to infinity. +We may proceed from a given pair in the descending line of generation +from father to son, and cogitate a never-ending line of descendants +from it. For in such a case reason does not demand absolute totality +in the series, because it does not presuppose it as a condition and +as given (datum), but merely as conditioned, and as capable of being +given (dabile). + +Very different is the case with the problem: "How far the regress, +which ascends from the given conditioned to the conditions, must +extend"; whether I can say: "It is a regress in infinitum," or only +"in indefinitum"; and whether, for example, setting out from the human +beings at present alive in the world, I may ascend in the series of +their ancestors, in infinitum--mr whether all that can be said is, +that so far as I have proceeded, I have discovered no empirical ground +for considering the series limited, so that I am justified, and +indeed, compelled to search for ancestors still further back, although +I am not obliged by the idea of reason to presuppose them. + +My answer to this question is: "If the series is given in +empirical intuition as a whole, the regress in the series of its +internal conditions proceeds in infinitum; but, if only one member +of the series is given, from which the regress is to proceed to +absolute totality, the regress is possible only in indefinitum." For +example, the division of a portion of matter given within certain +limits--of a body, that is--proceeds in infinitum. For, as the +condition of this whole is its part, and the condition of the part +a part of the part, and so on, and as in this regress of decomposition +an unconditioned indivisible member of the series of conditions is +not to be found; there are no reasons or grounds in experience for +stopping in the division, but, on the contrary, the more remote +members of the division are actually and empirically given prior to +this division. That is to say, the division proceeds to infinity. On +the other hand, the series of ancestors of any given human being is +not given, in its absolute totality, in any experience, and yet the +regress proceeds from every genealogical member of this series to +one still higher, and does not meet with any empirical limit +presenting an absolutely unconditioned member of the series. But as +the members of such a series are not contained in the empirical +intuition of the whole, prior to the regress, this regress does not +proceed to infinity, but only in indefinitum, that is, we are called +upon to discover other and higher members, which are themselves always +conditioned. + +In neither case--the regressus in infinitum, nor the regressus in +indefinitum, is the series of conditions to be considered as +actually infinite in the object itself. This might be true of things +in themselves, but it cannot be asserted of phenomena, which, as +conditions of each other, are only given in the empirical regress +itself. Hence, the question no longer is, "What is the quantity of +this series of conditions in itself--is it finite or infinite?" for +it is nothing in itself; but, "How is the empirical regress to be +commenced, and how far ought we to proceed with it?" And here a signal +distinction in the application of this rule becomes apparent. If the +whole is given empirically, it is possible to recede in the series +of its internal conditions to infinity. But if the whole is not given, +and can only be given by and through the empirical regress, I can only +say: "It is possible to infinity, to proceed to still higher +conditions in the series." In the first case, I am justified in +asserting that more members are empirically given in the object than +I attain to in the regress (of decomposition). In the second case, +I am justified only in saying, that I can always proceed further in +the regress, because no member of the series is given as absolutely +conditioned, and thus a higher member is possible, and an inquiry with +regard to it is necessary. In the one case it is necessary to find +other members of the series, in the other it is necessary to inquire +for others, inasmuch as experience presents no absolute limitation +of the regress. For, either you do not possess a perception which +absolutely limits your empirical regress, and in this case the regress +cannot be regarded as complete; or, you do possess such a limitative +perception, in which case it is not a part of your series (for that +which limits must be distinct from that which is limited by it), and +it is incumbent you to continue your regress up to this condition, +and so on. + +These remarks will be placed in their proper light by their +application in the following section. + + + +SECTION IX. Of the Empirical Use of the Regulative Principle + of Reason with regard to the Cosmological Ideas. + +We have shown that no transcendental use can be made either of the +conceptions of reason or of understanding. We have shown, likewise, +that the demand of absolute totality in the series of conditions in +the world of sense arises from a transcendental employment of +reason, resting on the opinion that phenomena are to be regarded as +things in themselves. It follows that we are not required to answer +the question respecting the absolute quantity of a series--whether +it is in itself limited or unlimited. We are only called upon to +determine how far we must proceed in the empirical regress from +condition to condition, in order to discover, in conformity with the +rule of reason, a full and correct answer to the questions proposed +by reason itself. + +This principle of reason is hence valid only as a rule for the +extension of a possible experience--its invalidity as a principle +constitutive of phenomena in themselves having been sufficiently +demonstrated. And thus, too, the antinomial conflict of reason with +itself is completely put an end to; inasmuch as we have not only +presented a critical solution of the fallacy lurking in the opposite +statements of reason, but have shown the true meaning of the ideas +which gave rise to these statements. The dialectical principle of +reason has, therefore, been changed into a doctrinal principle. But +in fact, if this principle, in the subjective signification which we +have shown to be its only true sense, may be guaranteed as a principle +of the unceasing extension of the employment of our understanding, +its influence and value are just as great as if it were an axiom for +the a priori determination of objects. For such an axiom could not +exert a stronger influence on the extension and rectification of our +knowledge, otherwise than by procuring for the principles of the +understanding the most widely expanded employment in the field of +experience. + + + +I. Solution of the Cosmological Idea of the Totality of the + Composition of Phenomena in the Universe. + +Here, as well as in the case of the other cosmological problems, the +ground of the regulative principle of reason is the proposition that +in our empirical regress no experience of an absolute limit, and +consequently no experience of a condition, which is itself +absolutely unconditioned, is discoverable. And the truth of this +proposition itself rests upon the consideration that such an +experience must represent to us phenomena as limited by nothing or +the mere void, on which our continued regress by means of perception +must abut--which is impossible. + +Now this proposition, which declares that every condition attained +in the empirical regress must itself be considered empirically +conditioned, contains the rule in terminis, which requires me, to +whatever extent I may have proceeded in the ascending series, always +to look for some higher member in the series--whether this member is +to become known to me through experience, or not. + +Nothing further is necessary, then, for the solution of the first +cosmological problem, than to decide, whether, in the regress to the +unconditioned quantity of the universe (as regards space and time), +this never limited ascent ought to be called a regressus in +infinitum or indefinitum. + +The general representation which we form in our minds of the +series of all past states or conditions of the world, or of all the +things which at present exist in it, is itself nothing more than a +possible empirical regress, which is cogitated--although in an +undetermined manner--in the mind, and which gives rise to the +conception of a series of conditions for a given object.* Now I have +a conception of the universe, but not an intuition--that is, not an +intuition of it as a whole. Thus I cannot infer the magnitude of the +regress from the quantity or magnitude of the world, and determine +the former by means of the latter; on the contrary, I must first of +all form a conception of the quantity or magnitude of the world from +the magnitude of the empirical regress. But of this regress I know +nothing more than that I ought to proceed from every given member of +the series of conditions to one still higher. But the quantity of the +universe is not thereby determined, and we cannot affirm that this +regress proceeds in infinitum. Such an affirmation would anticipate +the members of the series which have not yet been reached, and +represent the number of them as beyond the grasp of any empirical +synthesis; it would consequently determine the cosmical quantity prior +to the regress (although only in a negative manner)--which is +impossible. For the world is not given in its totality in any +intuition: consequently, its quantity cannot be given prior to the +regress. It follows that we are unable to make any declaration +respecting the cosmical quantity in itself--not even that the +regress in it is a regress in infinitum; we must only endeavour to +attain to a conception of the quantity of the universe, in +conformity with the rule which determines the empirical regress in +it. But this rule merely requires us never to admit an absolute limit +to our series--how far soever we may have proceeded in it, but always, +on the contrary, to subordinate every phenomenon to some other as its +condition, and consequently to proceed to this higher phenomenon. Such +a regress is, therefore, the regressus in indefinitum, which, as not +determining a quantity in the object, is clearly distinguishable +from the regressus in infinitum. + +[*Footnote: The cosmical series can neither be greater nor smaller +than the possible empirical regress, upon which its conception is based. +And as this regress cannot be a determinate infinite regress, still +less a determinate finite (absolutely limited), it is evident that +we cannot regard the world as either finite or infinite, because the +regress, which gives us the representation of the world, is neither +finite nor infinite.] + +It follows from what we have said that we are not justified in +declaring the world to be infinite in space, or as regards past +time. For this conception of an infinite given quantity is +empirical; but we cannot apply the conception of an infinite +quantity to the world as an object of the senses. I cannot say, "The +regress from a given perception to everything limited either in +space or time, proceeds in infinitum," for this presupposes an +infinite cosmical quantity; neither can I say, "It is finite," for +an absolute limit is likewise impossible in experience. It follows +that I am not entitled to make any assertion at all respecting the +whole object of experience--the world of sense; I must limit my +declarations to the rule according to which experience or empirical +knowledge is to be attained. + +To the question, therefore, respecting the cosmical quantity, the +first and negative answer is: "The world has no beginning in time, +and no absolute limit in space." + +For, in the contrary case, it would be limited by a void time on the +one hand, and by a void space on the other. Now, since the world, as +a phenomenon, cannot be thus limited in itself for a phenomenon is +not a thing in itself; it must be possible for us to have a perception +of this limitation by a void time and a void space. But such a +perception--such an experience is impossible; because it has no +content. Consequently, an absolute cosmical limit is empirically, +and therefore absolutely, impossible.* + +[*Footnote: The reader will remark that the proof presented above is +very different from the dogmatical demonstration given in the antithesis +of the first antinomy. In that demonstration, it was taken for granted +that the world is a thing in itself--given in its totality prior to +all regress, and a determined position in space and time was denied +to it--if it was not considered as occupying all time and all space. +Hence our conclusion differed from that given above; for we inferred +in the antithesis the actual infinity of the world.] + +From this follows the affirmative answer: "The regress in the series +of phenomena--as a determination of the cosmical quantity, proceeds +in indefinitum." This is equivalent to saying: "The world of sense +has no absolute quantity, but the empirical regress (through which +alone the world of sense is presented to us on the side of its conditions) +rests upon a rule, which requires it to proceed from every member of +the series, as conditioned, to one still more remote (whether +through personal experience, or by means of history, or the chain of +cause and effect), and not to cease at any point in this extension +of the possible empirical employment of the understanding." And this +is the proper and only use which reason can make of its principles. + +The above rule does not prescribe an unceasing regress in one kind +of phenomena. It does not, for example, forbid us, in our ascent +from an individual human being through the line of his ancestors, to +expect that we shall discover at some point of the regress a +primeval pair, or to admit, in the series of heavenly bodies, a sun +at the farthest possible distance from some centre. All that it demands +is a perpetual progress from phenomena to phenomena, even although +an actual perception is not presented by them (as in the case of our +perceptions being so weak as that we are unable to become conscious +of them), since they, nevertheless, belong to possible experience. + +Every beginning is in time, and all limits to extension are in +space. But space and time are in the world of sense. Consequently +phenomena in the world are conditionally limited, but the world itself +is not limited, either conditionally or unconditionally. + +For this reason, and because neither the world nor the cosmical +series of conditions to a given conditioned can be completely given, +our conception of the cosmical quantity is given only in and through +the regress and not prior to it--in a collective intuition. But the +regress itself is really nothing more than the determining of the +cosmical quantity, and cannot therefore give us any determined +conception of it--still less a conception of a quantity which is, in +relation to a certain standard, infinite. The regress does not, +therefore, proceed to infinity (an infinity given), but only to an +indefinite extent, for or the of presenting to us a quantity--realized +only in and through the regress itself. + + + +II. Solution of the Cosmological Idea of the Totality of + the Division of a Whole given in Intuition. + +When I divide a whole which is given in intuition, I proceed from +a conditioned to its conditions. The division of the parts of the +whole (subdivisio or decompositio) is a regress in the series of these +conditions. The absolute totality of this series would be actually +attained and given to the mind, if the regress could arrive at +simple parts. But if all the parts in a continuous decomposition are +themselves divisible, the division, that is to say, the regress, +proceeds from the conditioned to its conditions in infinitum; +because the conditions (the parts) are themselves contained in the +conditioned, and, as the latter is given in a limited intuition, the +former are all given along with it. This regress cannot, therefore, +be called a regressus in indefinitum, as happened in the case of the +preceding cosmological idea, the regress in which proceeded from the +conditioned to the conditions not given contemporaneously and along +with it, but discoverable only through the empirical regress. We are +not, however, entitled to affirm of a whole of this kind, which is +divisible in infinitum, that it consists of an infinite number of +parts. For, although all the parts are contained in the intuition of +the whole, the whole division is not contained therein. The division +is contained only in the progressing decomposition--in the regress +itself, which is the condition of the possibility and actuality of +the series. Now, as this regress is infinite, all the members (parts) +to which it attains must be contained in the given whole as an aggregate. +But the complete series of division is not contained therein. For this +series, being infinite in succession and always incomplete, cannot +represent an infinite number of members, and still less a +composition of these members into a whole. + +To apply this remark to space. Every limited part of space presented +to intuition is a whole, the parts of which are always spaces--to +whatever extent subdivided. Every limited space is hence divisible +to infinity. + +Let us again apply the remark to an external phenomenon enclosed +in limits, that is, a body. The divisibility of a body rests upon +the divisibility of space, which is the condition of the possibility +of the body as an extended whole. A body is consequently divisible +to infinity, though it does not, for that reason, consist of an +infinite number of parts. + +It certainly seems that, as a body must be cogitated as substance in +space, the law of divisibility would not be applicable to it as +substance. For we may and ought to grant, in the case of space, that +division or decomposition, to any extent, never can utterly annihilate +composition (that is to say, the smallest part of space must still +consist of spaces); otherwise space would entirely cease to exist- +which is impossible. But, the assertion on the other band that when +all composition in matter is annihilated in thought, nothing +remains, does not seem to harmonize with the conception of +substance, which must be properly the subject of all composition and +must remain, even after the conjunction of its attributes in space- +which constituted a body--is annihilated in thought. But this is not +the case with substance in the phenomenal world, which is not a +thing in itself cogitated by the pure category. Phenomenal substance +is not an absolute subject; it is merely a permanent sensuous image, +and nothing more than an intuition, in which the unconditioned is +not to be found. + +But, although this rule of progress to infinity is legitimate and +applicable to the subdivision of a phenomenon, as a mere occupation +or filling of space, it is not applicable to a whole consisting of +a number of distinct parts and constituting a quantum discretum--that +is to say, an organized body. It cannot be admitted that every part +in an organized whole is itself organized, and that, in analysing it +to infinity, we must always meet with organized parts; although we +may allow that the parts of the matter which we decompose in infinitum, +may be organized. For the infinity of the division of a phenomenon +in space rests altogether on the fact that the divisibility of a +phenomenon is given only in and through this infinity, that is, an +undetermined number of parts is given, while the parts themselves +are given and determined only in and through the subdivision; in a +word, the infinity of the division necessarily presupposes that the +whole is not already divided in se. Hence our division determines a +number of parts in the whole--a number which extends just as far as +the actual regress in the division; while, on the other hand, the very +notion of a body organized to infinity represents the whole as already +and in itself divided. We expect, therefore, to find in it a +determinate, but at the same time, infinite, number of parts--which +is self-contradictory. For we should thus have a whole containing a +series of members which could not be completed in any regress--which +is infinite, and at the same time complete in an organized +composite. Infinite divisibility is applicable only to a quantum +continuum, and is based entirely on the infinite divisibility of +space, But in a quantum discretum the multitude of parts or units is +always determined, and hence always equal to some number. To what +extent a body may be organized, experience alone can inform us; and +although, so far as our experience of this or that body has +extended, we may not have discovered any inorganic part, such parts +must exist in possible experience. But how far the transcendental +division of a phenomenon must extend, we cannot know from +experience--it is a question which experience cannot answer; it is +answered only by the principle of reason which forbids us to +consider the empirical regress, in the analysis of extended body, as +ever absolutely complete. + + + +Concluding Remark on the Solution of the Transcendental +Mathematical Ideas--and Introductory to the +Solution of the Dynamical Ideas. + +We presented the antinomy of pure reason in a tabular form, and we +endeavoured to show the ground of this self-contradiction on the +part of reason, and the only means of bringing it to a conclusion-- +namely, by declaring both contradictory statements to be false. We +represented in these antinomies the conditions of phenomena as +belonging to the conditioned according to relations of space and time- +which is the usual supposition of the common understanding. In this +respect, all dialectical representations of totality, in the series +of conditions to a given conditioned, were perfectly homogeneous. The +condition was always a member of the series along with the +conditioned, and thus the homogeneity of the whole series was assured. +In this case the regress could never be cogitated as complete; or, +if this was the case, a member really conditioned was falsely regarded +as a primal member, consequently as unconditioned. In such an +antinomy, therefore, we did not consider the object, that is, the +conditioned, but the series of conditions belonging to the object, +and the magnitude of that series. And thus arose the difficulty--a +difficulty not to be settled by any decision regarding the claims of +the two parties, but simply by cutting the knot--by declaring the +series proposed by reason to be either too long or too short for the +understanding, which could in neither case make its conceptions +adequate with the ideas. + +But we have overlooked, up to this point, an essential difference +existing between the conceptions of the understanding which reason +endeavours to raise to the rank of ideas--two of these indicating a +mathematical, and two a dynamical synthesis of phenomena. Hitherto, +it was necessary to signalize this distinction; for, just as in our +general representation of all transcendental ideas, we considered them +under phenomenal conditions, so, in the two mathematical ideas, our +discussion is concerned solely with an object in the world of +phenomena. But as we are now about to proceed to the consideration +of the dynamical conceptions of the understanding, and their +adequateness with ideas, we must not lose sight of this distinction. +We shall find that it opens up to us an entirely new view of the +conflict in which reason is involved. For, while in the first two +antinomies, both parties were dismissed, on the ground of having +advanced statements based upon false hypothesis; in the present case +the hope appears of discovering a hypothesis which may be consistent +with the demands of reason, and, the judge completing the statement +of the grounds of claim, which both parties had left in an unsatisfactory +state, the question may be settled on its own merits, not by +dismissing the claimants, but by a comparison of the arguments on both +sides. If we consider merely their extension, and whether they are +adequate with ideas, the series of conditions may be regarded as all +homogeneous. But the conception of the understanding which lies at +the basis of these ideas, contains either a synthesis of the homogeneous +(presupposed in every quantity--in its composition as well as in its +division) or of the heterogeneous, which is the case in the +dynamical synthesis of cause and effect, as well as of the necessary +and the contingent. + +Thus it happens that in the mathematical series of phenomena no +other than a sensuous condition is admissible--a condition which is +itself a member of the series; while the dynamical series of +sensuous conditions admits a heterogeneous condition, which is not +a member of the series, but, as purely intelligible, lies out of and +beyond it. And thus reason is satisfied, and an unconditioned placed +at the head of the series of phenomena, without introducing +confusion into or discontinuing it, contrary to the principles of +the understanding. + +Now, from the fact that the dynamical ideas admit a condition of +phenomena which does not form a part of the series of phenomena, +arises a result which we should not have expected from an antinomy. +In former cases, the result was that both contradictory dialectical +statements were declared to be false. In the present case, we find +the conditioned in the dynamical series connected with an empirically +unconditioned, but non-sensuous condition; and thus satisfaction is +done to the understanding on the one hand and to the reason on the +other.* While, moreover, the dialectical arguments for unconditioned +totality in mere phenomena fall to the ground, both propositions of +reason may be shown to be true in their proper signification. This +could not happen in the case of the cosmological ideas which +demanded a mathematically unconditioned unity; for no condition +could be placed at the head of the series of phenomena, except one +which was itself a phenomenon and consequently a member of the series. + +[*Footnote: For the understanding cannot admit among phenomena a condition +which is itself empirically unconditioned. But if it is possible to +cogitate an intelligible condition--one which is not a member of the +series of phenomena--for a conditioned phenomenon, without breaking +the series of empirical conditions, such a condition may be admissible +as empirically unconditioned, and the empirical regress continue +regular, unceasing, and intact.] + + + +III. Solution of the Cosmological Idea of the Totality of + the Deduction of Cosmical Events from their Causes. + +There are only two modes of causality cogitable--the causality of +nature or of freedom. The first is the conjunction of a particular +state with another preceding it in the world of sense, the former +following the latter by virtue of a law. Now, as the causality of +phenomena is subject to conditions of time, and the preceding state, +if it had always existed, could not have produced an effect which +would make its first appearance at a particular time, the causality +of a cause must itself be an effect--must itself have begun to be, +and therefore, according to the principle of the understanding, itself +requires a cause. + +We must understand, on the contrary, by the term freedom, in the +cosmological sense, a faculty of the spontaneous origination of a +state; the causality of which, therefore, is not subordinated to +another cause determining it in time. Freedom is in this sense a +pure transcendental idea, which, in the first place, contains no +empirical element; the object of which, in the second place, cannot +be given or determined in any experience, because it is a universal +law of the very possibility of experience, that everything which happens +must have a cause, that consequently the causality of a cause, being +itself something that has happened, must also have a cause. In this +view of the case, the whole field of experience, how far soever it +may extend, contains nothing that is not subject to the laws of nature. +But, as we cannot by this means attain to an absolute totality of +conditions in reference to the series of causes and effects, reason +creates the idea of a spontaneity, which can begin to act of itself, +and without any external cause determining it to action, according +to the natural law of causality. + +It is especially remarkable that the practical conception of freedom +is based upon the transcendental idea, and that the question of the +possibility of the former is difficult only as it involves the +consideration of the truth of the latter. Freedom, in the practical +sense, is the independence of the will of coercion by sensuous +impulses. A will is sensuous, in so far as it is pathologically +affected (by sensuous impulses); it is termed animal (arbitrium +brutum), when it is pathologically necessitated. The human will is +certainly an arbitrium sensitivum, not brutum, but liberum; because +sensuousness does not necessitate its action, a faculty existing in +man of self-determination, independently of all sensuous coercion. + +It is plain that, if all causality in the world of sense were +natural--and natural only--every event would be determined by +another according to necessary laws, and that, consequently, +phenomena, in so far as they determine the will, must necessitate +every action as a natural effect from themselves; and thus all +practical freedom would fall to the ground with the transcendental +idea. For the latter presupposes that although a certain thing has +not happened, it ought to have happened, and that, consequently, its +phenomenal cause was not so powerful and determinative as to exclude +the causality of our will--a causality capable of producing effects +independently of and even in opposition to the power of natural +causes, and capable, consequently, of spontaneously originating a +series of events. + +Here, too, we find it to be the case, as we generally found in the +self-contradictions and perplexities of a reason which strives to pass +the bounds of possible experience, that the problem is properly not +physiological, but transcendental. The question of the possibility +of freedom does indeed concern psychology; but, as it rests upon +dialectical arguments of pure reason, its solution must engage the +attention of transcendental philosophy. Before attempting this +solution, a task which transcendental philosophy cannot decline, it +will be advisable to make a remark with regard to its procedure in +the settlement of the question. + +If phenomena were things in themselves, and time and space forms +of the existence of things, condition and conditioned would always +be members of the same series; and thus would arise in the present +case the antinomy common to all transcendental ideas--that their +series is either too great or too small for the understanding. The +dynamical ideas, which we are about to discuss in this and the +following section, possess the peculiarity of relating to an object, +not considered as a quantity, but as an existence; and thus, in the +discussion of the present question, we may make abstraction of the +quantity of the series of conditions, and consider merely the +dynamical relation of the condition to the conditioned. The +question, then, suggests itself, whether freedom is possible; and, +if it is, whether it can consist with the universality of the +natural law of causality; and, consequently, whether we enounce a +proper disjunctive proposition when we say: "Every effect must have +its origin either in nature or in freedom," or whether both cannot +exist together in the same event in different relations. The principle +of an unbroken connection between all events in the phenomenal +world, in accordance with the unchangeable laws of nature, is a +well-established principle of transcendental analytic which admits +of no exception. The question, therefore, is: "Whether an effect, +determined according to the laws of nature, can at the same time be +produced by a free agent, or whether freedom and nature mutually +exclude each other?" And here, the common but fallacious hypothesis +of the absolute reality of phenomena manifests its injurious influence +in embarrassing the procedure of reason. For if phenomena are things +in themselves, freedom is impossible. In this case, nature is the +complete and all-sufficient cause of every event; and condition and +conditioned, cause and effect are contained in the same series, and +necessitated by the same law. If, on the contrary, phenomena are +held to be, as they are in fact, nothing more than mere +representations, connected with each other in accordance with +empirical laws, they must have a ground which is not phenomenal. But +the causality of such an intelligible cause is not determined or +determinable by phenomena; although its effects, as phenomena, must +be determined by other phenomenal existences. This cause and its +causality exist therefore out of and apart from the series of +phenomena; while its effects do exist and are discoverable in the +series of empirical conditions. Such an effect may therefore be +considered to be free in relation to its intelligible cause, and +necessary in relation to the phenomena from which it is a necessary +consequence--a distinction which, stated in this perfectly general +and abstract manner, must appear in the highest degree subtle and obscure. +The sequel will explain. It is sufficient, at present, to remark that, +as the complete and unbroken connection of phenomena is an unalterable +law of nature, freedom is impossible--on the supposition that +phenomena are absolutely real. Hence those philosophers who adhere +to the common opinion on this subject can never succeed in reconciling +the ideas of nature and freedom. + + + +Possibility of Freedom in Harmony with the Universal Law +of Natural Necessity. + +That element in a sensuous object which is not itself sensuous, I +may be allowed to term intelligible. If, accordingly, an object +which must be regarded as a sensuous phenomenon possesses a faculty +which is not an object of sensuous intuition, but by means of which +it is capable of being the cause of phenomena, the causality of an +object or existence of this kind may be regarded from two different +points of view. It may be considered to be intelligible, as regards +its action--the action of a thing which is a thing in itself, and +sensuous, as regards its effects--the effects of a phenomenon +belonging to the sensuous world. We should accordingly, have to form +both an empirical and an intellectual conception of the causality of +such a faculty or power--both, however, having reference to the same +effect. This twofold manner of cogitating a power residing in a +sensuous object does not run counter to any of the conceptions which +we ought to form of the world of phenomena or of a possible +experience. Phenomena--not being things in themselves--must have a +transcendental object as a foundation, which determines them as mere +representations; and there seems to be no reason why we should not +ascribe to this transcendental object, in addition to the property +of self-phenomenization, a causality whose effects are to be met +with in the world of phenomena, although it is not itself a +phenomenon. But every effective cause must possess a character, that +is to say, a law of its causality, without which it would cease to +be a cause. In the above case, then, every sensuous object would +possess an empirical character, which guaranteed that its actions, +as phenomena, stand in complete and harmonious connection, conformably +to unvarying natural laws, with all other phenomena, and can be +deduced from these, as conditions, and that they do thus, in +connection with these, constitute a series in the order of nature. +This sensuous object must, in the second place, possess an +intelligible character, which guarantees it to be the cause of those +actions, as phenomena, although it is not itself a phenomenon nor +subordinate to the conditions of the world of sense. The former may +be termed the character of the thing as a phenomenon, the latter the +character of the thing as a thing in itself. + +Now this active subject would, in its character of intelligible +subject, be subordinate to no conditions of time, for time is only +a condition of phenomena, and not of things in themselves. No action +would begin or cease to be in this subject; it would consequently be +free from the law of all determination of time--the law of change, +namely, that everything which happens must have a cause in the +phenomena of a preceding state. In one word, the causality of the +subject, in so far as it is intelligible, would not form part of the +series of empirical conditions which determine and necessitate an +event in the world of sense. Again, this intelligible character of +a thing cannot be immediately cognized, because we can perceive +nothing but phenomena, but it must be capable of being cogitated in +harmony with the empirical character; for we always find ourselves +compelled to place, in thought, a transcendental object at the basis +of phenomena although we can never know what this object is in itself. + +In virtue of its empirical character, this subject would at the same +time be subordinate to all the empirical laws of causality, and, as +a phenomenon and member of the sensuous world, its effects would +have to be accounted for by a reference to preceding phenomena. +Eternal phenomena must be capable of influencing it; and its +actions, in accordance with natural laws, must explain to us how its +empirical character, that is, the law of its causality, is to be +cognized in and by means of experience. In a word, all requisites +for a complete and necessary determination of these actions must be +presented to us by experience. + +In virtue of its intelligible character, on the other hand (although +we possess only a general conception of this character), the subject +must be regarded as free from all sensuous influences, and from all +phenomenal determination. Moreover, as nothing happens in this +subject--for it is a noumenon, and there does not consequently exist +in it any change, demanding the dynamical determination of time, and +for the same reason no connection with phenomena as causes--this +active existence must in its actions be free from and independent of +natural necessity, for or necessity exists only in the world of +phenomena. It would be quite correct to say that it originates or +begins its effects in the world of sense from itself, although the +action productive of these effects does not begin in itself. We should +not be in this case affirming that these sensuous effects began to +exist of themselves, because they are always determined by prior +empirical conditions--by virtue of the empirical character, which is +the phenomenon of the intelligible character--and are possible only +as constituting a continuation of the series of natural causes. And +thus nature and freedom, each in the complete and absolute +signification of these terms, can exist, without contradiction or +disagreement, in the same action. + + + +Exposition of the Cosmological Idea of Freedom in Harmony +with the Universal Law of Natural Necessity. + +I have thought it advisable to lay before the reader at first merely +a sketch of the solution of this transcendental problem, in order to +enable him to form with greater ease a clear conception of the +course which reason must adopt in the solution. I shall now proceed +to exhibit the several momenta of this solution, and to consider them +in their order. + +The natural law that everything which happens must have a cause, +that the causality of this cause, that is, the action of the cause +(which cannot always have existed, but must be itself an event, for +it precedes in time some effect which it has originated), must have +itself a phenomenal cause, by which it is determined and, and, +consequently, all events are empirically determined in an order of +nature--this law, I say, which lies at the foundation of the +possibility of experience, and of a connected system of phenomena or +nature is a law of the understanding, from which no departure, and +to which no exception, can be admitted. For to except even a single +phenomenon from its operation is to exclude it from the sphere of +possible experience and thus to admit it to be a mere fiction of +thought or phantom of the brain. + +Thus we are obliged to acknowledge the existence of a chain of +causes, in which, however, absolute totality cannot be found. But we +need not detain ourselves with this question, for it has already +been sufficiently answered in our discussion of the antinomies into +which reason falls, when it attempts to reach the unconditioned in +the series of phenomena. If we permit ourselves to be deceived by the +illusion of transcendental idealism, we shall find that neither nature +nor freedom exists. Now the question is: "Whether, admitting the +existence of natural necessity in the world of phenomena, it is +possible to consider an effect as at the same time an effect of nature +and an effect of freedom--or, whether these two modes of causality +are contradictory and incompatible?" + +No phenomenal cause can absolutely and of itself begin a series. +Every action, in so far as it is productive of an event, is itself +an event or occurrence, and presupposes another preceding state, in +which its cause existed. Thus everything that happens is but a +continuation of a series, and an absolute beginning is impossible in +the sensuous world. The actions of natural causes are, accordingly, +themselves effects, and presuppose causes preceding them in time. A +primal action which forms an absolute beginning, is beyond the +causal power of phenomena. + +Now, is it absolutely necessary that, granting that all effects +are phenomena, the causality of the cause of these effects must also +be a phenomenon and belong to the empirical world? Is it not rather +possible that, although every effect in the phenomenal world must be +connected with an empirical cause, according to the universal law of +nature, this empirical causality may be itself the effect of a +non-empirical and intelligible causality--its connection with +natural causes remaining nevertheless intact? Such a causality would +be considered, in reference to phenomena, as the primal action of a +cause, which is in so far, therefore, not phenomenal, but, by reason +of this faculty or power, intelligible; although it must, at the +same time, as a link in the chain of nature, be regarded as +belonging to the sensuous world. + +A belief in the reciprocal causality of phenomena is necessary, if +we are required to look for and to present the natural conditions of +natural events, that is to say, their causes. This being admitted as +unexceptionably valid, the requirements of the understanding, which +recognizes nothing but nature in the region of phenomena, are +satisfied, and our physical explanations of physical phenomena may +proceed in their regular course, without hindrance and without +opposition. But it is no stumbling-block in the way, even assuming +the idea to be a pure fiction, to admit that there are some natural +causes in the possession of a faculty which is not empirical, but +intelligible, inasmuch as it is not determined to action by +empirical conditions, but purely and solely upon grounds brought +forward by the understanding--this action being still, when the +cause is phenomenized, in perfect accordance with the laws of +empirical causality. Thus the acting subject, as a causal +phenomenon, would continue to preserve a complete connection with +nature and natural conditions; and the phenomenon only of the +subject (with all its phenomenal causality) would contain certain +conditions, which, if we ascend from the empirical to the +transcendental object, must necessarily be regarded as intelligible. +For, if we attend, in our inquiries with regard to causes in the world +of phenomena, to the directions of nature alone, we need not trouble +ourselves about the relation in which the transcendental subject, +which is completely unknown to us, stands to these phenomena and their +connection in nature. The intelligible ground of phenomena in this +subject does not concern empirical questions. It has to do only with +pure thought; and, although the effects of this thought and action +of the pure understanding are discoverable in phenomena, these +phenomena must nevertheless be capable of a full and complete +explanation, upon purely physical grounds and in accordance with +natural laws. And in this case we attend solely to their empirical +and omit all consideration of their intelligible character (which is +the transcendental cause of the former) as completely unknown, except +in so far as it is exhibited by the latter as its empirical symbol. +Now let us apply this to experience. Man is a phenomenon of the sensuous +world and, at the same time, therefore, a natural cause, the causality +of which must be regulated by empirical laws. As such, he must possess +an empirical character, like all other natural phenomena. We remark +this empirical character in his actions, which reveal the presence +of certain powers and faculties. If we consider inanimate or merely +animal nature, we can discover no reason for ascribing to ourselves +any other than a faculty which is determined in a purely sensuous +manner. But man, to whom nature reveals herself only through sense, +cognizes himself not only by his senses, but also through pure +apperception; and this in actions and internal determinations, which +he cannot regard as sensuous impressions. He is thus to himself, on +the one hand, a phenomenon, but on the other hand, in respect of +certain faculties, a purely intelligible object--intelligible, because +its action cannot be ascribed to sensuous receptivity. These faculties +are understanding and reason. The latter, especially, is in a peculiar +manner distinct from all empirically-conditioned faculties, for it +employs ideas alone in the consideration of its objects, and by +means of these determines the understanding, which then proceeds to +make an empirical use of its own conceptions, which, like the ideas +of reason, are pure and non-empirical. + +That reason possesses the faculty of causality, or that at least +we are compelled so to represent it, is evident from the +imperatives, which in the sphere of the practical we impose on many +of our executive powers. The words I ought express a species of +necessity, and imply a connection with grounds which nature does not +and cannot present to the mind of man. Understanding knows nothing +in nature but that which is, or has been, or will be. It would be +absurd to say that anything in nature ought to be other than it is +in the relations of time in which it stands; indeed, the ought, when +we consider merely the course of nature, has neither application nor +meaning. The question, "What ought to happen in the sphere of nature?" +is just as absurd as the question, "What ought to be the properties +of a circle?" All that we are entitled to ask is, "What takes place +in nature?" or, in the latter case, "What are the properties of a +circle?" + +But the idea of an ought or of duty indicates a possible action, the +ground of which is a pure conception; while the ground of a merely +natural action is, on the contrary, always a phenomenon. This action +must certainly be possible under physical conditions, if it is +prescribed by the moral imperative ought; but these physical or +natural conditions do not concern the determination of the will +itself, they relate to its effects alone, and the consequences of +the effect in the world of phenomena. Whatever number of motives +nature may present to my will, whatever sensuous impulses--the moral +ought it is beyond their power to produce. They may produce a +volition, which, so far from being necessary, is always conditioned--a +volition to which the ought enunciated by reason, sets an aim and a +standard, gives permission or prohibition. Be the object what it +may, purely sensuous--as pleasure, or presented by pure reason--as +good, reason will not yield to grounds which have an empirical origin. +Reason will not follow the order of things presented by experience, +but, with perfect spontaneity, rearranges them according to ideas, +with which it compels empirical conditions to agree. It declares, in +the name of these ideas, certain actions to be necessary which +nevertheless have not taken place and which perhaps never will take +place; and yet presupposes that it possesses the faculty of +causality in relation to these actions. For, in the absence of this +supposition, it could not expect its ideas to produce certain +effects in the world of experience. + +Now, let us stop here and admit it to be at least possible that +reason does stand in a really causal relation to phenomena. In this +case it must--pure reason as it is--exhibit an empirical character. +For every cause supposes a rule, according to which certain +phenomena follow as effects from the cause, and every rule requires +uniformity in these effects; and this is the proper ground of the +conception of a cause--as a faculty or power. Now this conception +(of a cause) may be termed the empirical character of reason; and this +character is a permanent one, while the effects produced appear, in +conformity with the various conditions which accompany and partly +limit them, in various forms. + +Thus the volition of every man has an empirical character, which +is nothing more than the causality of his reason, in so far as its +effects in the phenomenal world manifest the presence of a rule, +according to which we are enabled to examine, in their several kinds +and degrees, the actions of this causality and the rational grounds +for these actions, and in this way to decide upon the subjective +principles of the volition. Now we learn what this empirical character +is only from phenomenal effects, and from the rule of these which is +presented by experience; and for this reason all the actions of man +in the world of phenomena are determined by his empirical character, +and the co-operative causes of nature. If, then, we could +investigate all the phenomena of human volition to their lowest +foundation in the mind, there would be no action which we could not +anticipate with certainty, and recognize to be absolutely necessary +from its preceding conditions. So far as relates to this empirical +character, therefore, there can be no freedom; and it is only in the +light of this character that we can consider the human will, when we +confine ourselves to simple observation and, as is the case in +anthropology, institute a physiological investigation of the motive +causes of human actions. + +But when we consider the same actions in relation to reason--not for +the purpose of explaining their origin, that is, in relation to +speculative reason, but to practical reason, as the producing cause +of these actions--we shall discover a rule and an order very different +from those of nature and experience. For the declaration of this +mental faculty may be that what has and could not but take place in +the course of nature, ought not to have taken place. Sometimes, too, +we discover, or believe that we discover, that the ideas of reason +did actually stand in a causal relation to certain actions of man; +and that these actions have taken place because they were determined, +not by empirical causes, but by the act of the will upon grounds of +reason. + +Now, granting that reason stands in a causal relation to +phenomena; can an action of reason be called free, when we know +that, sensuously, in its empirical character, it is completely +determined and absolutely necessary? But this empirical character is +itself determined by the intelligible character. The latter we +cannot cognize; we can only indicate it by means of phenomena, which +enable us to have an immediate cognition only of the empirical +character.* An action, then, in so far as it is to be ascribed to an +intelligible cause, does not result from it in accordance with +empirical laws. That is to say, not the conditions of pure reason, +but only their effects in the internal sense, precede the act. Pure +reason, as a purely intelligible faculty, is not subject to the +conditions of time. The causality of reason in its intelligible +character does not begin to be; it does not make its appearance at +a certain time, for the purpose of producing an effect. If this were +not the case, the causality of reason would be subservient to the +natural law of phenomena, which determines them according to time, +and as a series of causes and effects in time; it would consequently +cease to be freedom and become a part of nature. We are therefore +justified in saying: "If reason stands in a causal relation to +phenomena, it is a faculty which originates the sensuous condition +of an empirical series of effects." For the condition, which resides +in the reason, is non-sensuous, and therefore cannot be originated, +or begin to be. And thus we find--what we could not discover in any +empirical series--a condition of a successive series of events +itself empirically unconditioned. For, in the present case, the +condition stands out of and beyond the series of phenomena--it is +intelligible, and it consequently cannot be subjected to any +sensuous condition, or to any time-determination by a preceding cause. + +[*Footnote: The real morality of actions--their merit or demerit, and +even that of our own conduct, is completely unknown to us. Our estimates +can relate only to their empirical character. How much is the result +of the action of free will, how much is to be ascribed to nature and +to blameless error, or to a happy constitution of temperament (merito +fortunae), no one can discover, nor, for this reason, determine with +perfect justice.] + +But, in another respect, the same cause belongs also to the series +of phenomena. Man is himself a phenomenon. His will has an empirical +character, which is the empirical cause of all his actions. There is +no condition--determining man and his volition in conformity with this +character--which does not itself form part of the series of effects +in nature, and is subject to their law--the law according to which +an empirically undetermined cause of an event in time cannot exist. +For this reason no given action can have an absolute and spontaneous +origination, all actions being phenomena, and belonging to the world +of experience. But it cannot be said of reason, that the state in +which it determines the will is always preceded by some other state +determining it. For reason is not a phenomenon, and therefore not +subject to sensuous conditions; and, consequently, even in relation +to its causality, the sequence or conditions of time do not influence +reason, nor can the dynamical law of nature, which determines the +sequence of time according to certain rules, be applied to it. + +Reason is consequently the permanent condition of all actions of the +human will. Each of these is determined in the empirical character +of the man, even before it has taken place. The intelligible +character, of which the former is but the sensuous schema, knows no +before or after; and every action, irrespective of the time-relation +in which it stands with other phenomena, is the immediate effect of +the intelligible character of pure reason, which, consequently, enjoys +freedom of action, and is not dynamically determined either by +internal or external preceding conditions. This freedom must not be +described, in a merely negative manner, as independence of empirical +conditions, for in this case the faculty of reason would cease to be +a cause of phenomena; but it must be regarded, positively, as a +faculty which can spontaneously originate a series of events. At the +same time, it must not be supposed that any beginning can take place +in reason; on the contrary, reason, as the unconditioned condition +of all action of the will, admits of no time-conditions, although +its effect does really begin in a series of phenomena--a beginning +which is not, however, absolutely primal. + +I shall illustrate this regulative principle of reason by an +example, from its employment in the world of experience; proved it +cannot be by any amount of experience, or by any number of facts, +for such arguments cannot establish the truth of transcendental +propositions. Let us take a voluntary action--for example, a +falsehood--by means of which a man has introduced a certain degree +of confusion into the social life of humanity, which is judged +according to the motives from which it originated, and the blame of +which and of the evil consequences arising from it, is imputed to +the offender. We at first proceed to examine the empirical character +of the offence, and for this purpose we endeavour to penetrate to +the sources of that character, such as a defective education, bad +company, a shameless and wicked disposition, frivolity, and want of +reflection--not forgetting also the occasioning causes which prevailed +at the moment of the transgression. In this the procedure is exactly +the same as that pursued in the investigation of the series of +causes which determine a given physical effect. Now, although we +believe the action to have been determined by all these circumstances, +we do not the less blame the offender. We do not blame him for his +unhappy disposition, nor for the circumstances which influenced him, +nay, not even for his former course of life; for we presuppose that +all these considerations may be set aside, that the series of +preceding conditions may be regarded as having never existed, and that +the action may be considered as completely unconditioned in relation +to any state preceding, just as if the agent commenced with it an +entirely new series of effects. Our blame of the offender is +grounded upon a law of reason, which requires us to regard this +faculty as a cause, which could have and ought to have otherwise +determined the behaviour of the culprit, independently of all +empirical conditions. This causality of reason we do not regard as +a co-operating agency, but as complete in itself. It matters not whether +the sensuous impulses favoured or opposed the action of this +causality, the offence is estimated according to its intelligible +character--the offender is decidedly worthy of blame, the moment he +utters a falsehood. It follows that we regard reason, in spite of +the empirical conditions of the act, as completely free, and +therefore, therefore, as in the present case, culpable. + +The above judgement is complete evidence that we are accustomed to +think that reason is not affected by sensuous conditions, that in it +no change takes place--although its phenomena, in other words, the +mode in which it appears in its effects, are subject to change--that +in it no preceding state determines the following, and, +consequently, that it does not form a member of the series of sensuous +conditions which necessitate phenomena according to natural laws. +Reason is present and the same in all human actions and at all +times; but it does not itself exist in time, and therefore does not +enter upon any state in which it did not formerly exist. It is, +relatively to new states or conditions, determining, but not +determinable. Hence we cannot ask: "Why did not reason determine +itself in a different manner?" The question ought to be thus stated: +"Why did not reason employ its power of causality to determine certain +phenomena in a different manner?" But this is a question which admits +of no answer. For a different intelligible character would have +exhibited a different empirical character; and, when we say that, in +spite of the course which his whole former life has taken, the +offender could have refrained from uttering the falsehood, this +means merely that the act was subject to the power and authority- +permissive or prohibitive--of reason. Now, reason is not subject in +its causality to any conditions of phenomena or of time; and a +difference in time may produce a difference in the relation of +phenomena to each other--for these are not things and therefore not +causes in themselves--but it cannot produce any difference in the +relation in which the action stands to the faculty of reason. + +Thus, then, in our investigation into free actions and the causal +power which produced them, we arrive at an intelligible cause, +beyond which, however, we cannot go; although we can recognize that +it is free, that is, independent of all sensuous conditions, and that, +in this way, it may be the sensuously unconditioned condition of +phenomena. But for what reason the intelligible character generates +such and such phenomena and exhibits such and such an empirical +character under certain circumstances, it is beyond the power of our +reason to decide. The question is as much above the power and the +sphere of reason as the following would be: "Why does the +transcendental object of our external sensuous intuition allow of no +other form than that of intuition in space?" But the problem, which +we were called upon to solve, does not require us to entertain any +such questions. The problem was merely this--whether freedom and natural +necessity can exist without opposition in the same action. To this +question we have given a sufficient answer; for we have shown that, +as the former stands in a relation to a different kind of condition +from those of the latter, the law of the one does not affect the law +of the other and that, consequently, both can exist together in +independence of and without interference with each other. + +The reader must be careful to remark that my intention in the +above remarks has not been to prove the actual existence of freedom, +as a faculty in which resides the cause of certain sensuous phenomena. +For, not to mention that such an argument would not have a +transcendental character, nor have been limited to the discussion of +pure conceptions--all attempts at inferring from experience what +cannot be cogitated in accordance with its laws, must ever be +unsuccessful. Nay, more, I have not even aimed at demonstrating the +possibility of freedom; for this too would have been a vain endeavour, +inasmuch as it is beyond the power of the mind to cognize the +possibility of a reality or of a causal power by the aid of mere a +priori conceptions. Freedom has been considered in the foregoing +remarks only as a transcendental idea, by means of which reason aims +at originating a series of conditions in the world of phenomena with +the help of that which is sensuously unconditioned, involving +itself, however, in an antinomy with the laws which itself +prescribes for the conduct of the understanding. That this antinomy +is based upon a mere illusion, and that nature and freedom are at least +not opposed--this was the only thing in our power to prove, and the +question which it was our task to solve. + + + +IV. Solution of the Cosmological Idea of the Totality of + the Dependence of Phenomenal Existences. + +In the preceding remarks, we considered the changes in the world +of sense as constituting a dynamical series, in which each member is +subordinated to another--as its cause. Our present purpose is to avail +ourselves of this series of states or conditions as a guide to an +existence which may be the highest condition of all changeable +phenomena, that is, to a necessary being. Our endeavour to reach, +not the unconditioned causality, but the unconditioned existence, of +substance. The series before us is therefore a series of +conceptions, and not of intuitions (in which the one intuition is +the condition of the other). + +But it is evident that, as all phenomena are subject to change and +conditioned in their existence, the series of dependent existences +cannot embrace an unconditioned member, the existence of which would +be absolutely necessary. It follows that, if phenomena were things +in themselves, and--as an immediate consequence from this supposition- +condition and conditioned belonged to the same series of phenomena, +the existence of a necessary being, as the condition of the +existence of sensuous phenomena, would be perfectly impossible. + +An important distinction, however, exists between the dynamical +and the mathematical regress. The latter is engaged solely with the +combination of parts into a whole, or with the division of a whole +into its parts; and therefore are the conditions of its series parts +of the series, and to be consequently regarded as homogeneous, and +for this reason, as consisting, without exception, of phenomena. If +the former regress, on the contrary, the aim of which is not to +establish the possibility of an unconditioned whole consisting of +given parts, or of an unconditioned part of a given whole, but to +demonstrate the possibility of the deduction of a certain state from +its cause, or of the contingent existence of substance from that which +exists necessarily, it is not requisite that the condition should form +part of an empirical series along with the conditioned. + +In the case of the apparent antinomy with which we are at present +dealing, there exists a way of escape from the difficulty; for it is +not impossible that both of the contradictory statements may be true +in different relations. All sensuous phenomena may be contingent, +and consequently possess only an empirically conditioned existence, +and yet there may also exist a non-empirical condition of the whole +series, or, in other words, a necessary being. For this necessary +being, as an intelligible condition, would not form a member--not even +the highest member--of the series; the whole world of sense would be +left in its empirically determined existence uninterfered with and +uninfluenced. This would also form a ground of distinction between +the modes of solution employed for the third and fourth antinomies. +For, while in the consideration of freedom in the former antinomy, +the thing itself--the cause (substantia phaenomenon)--was regarded +as belonging to the series of conditions, and only its causality to +the intelligible world--we are obliged in the present case to cogitate +this necessary being as purely intelligible and as existing entirely +apart from the world of sense (as an ens extramundanum); for otherwise +it would be subject to the phenomenal law of contingency and +dependence. + +In relation to the present problem, therefore, the regulative +principle of reason is that everything in the sensuous world possesses +an empirically conditioned existence--that no property of the sensuous +world possesses unconditioned necessity--that we are bound to +expect, and, so far as is possible, to seek for the empirical +condition of every member in the series of conditions--and that +there is no sufficient reason to justify us in deducing any +existence from a condition which lies out of and beyond the +empirical series, or in regarding any existence as independent and +self-subsistent; although this should not prevent us from +recognizing the possibility of the whole series being based upon a +being which is intelligible, and for this reason free from all +empirical conditions. + +But it has been far from my intention, in these remarks, to prove +the existence of this unconditioned and necessary being, or even to +evidence the possibility of a purely intelligible condition of the +existence or all sensuous phenomena. As bounds were set to reason, +to prevent it from leaving the guiding thread of empirical +conditions and losing itself in transcendent theories which are +incapable of concrete presentation; so it was my purpose, on the other +band, to set bounds to the law of the purely empirical +understanding, and to protest against any attempts on its part at +deciding on the possibility of things, or declaring the existence of +the intelligible to be impossible, merely on the ground that it is +not available for the explanation and exposition of phenomena. It has +been shown, at the same time, that the contingency of all the phenomena +of nature and their empirical conditions is quite consistent with +the arbitrary hypothesis of a necessary, although purely +intelligible condition, that no real contradiction exists between them +and that, consequently, both may be true. The existence of such an +absolutely necessary being may be impossible; but this can never be +demonstrated from the universal contingency and dependence of sensuous +phenomena, nor from the principle which forbids us to discontinue +the series at some member of it, or to seek for its cause in some +sphere of existence beyond the world of nature. Reason goes its way +in the empirical world, and follows, too, its peculiar path in the +sphere of the transcendental. + +The sensuous world contains nothing but phenomena, which are mere +representations, and always sensuously conditioned; things in +themselves are not, and cannot be, objects to us. It is not to be +wondered at, therefore, that we are not justified in leaping from some +member of an empirical series beyond the world of sense, as if +empirical representations were things in themselves, existing apart +from their transcendental ground in the human mind, and the cause of +whose existence may be sought out of the empirical series. This +would certainly be the case with contingent things; but it cannot be +with mere representations of things, the contingency of which is +itself merely a phenomenon and can relate to no other regress than +that which determines phenomena, that is, the empirical. But to +cogitate an intelligible ground of phenomena, as free, moreover, +from the contingency of the latter, conflicts neither with the +unlimited nature of the empirical regress, nor with the complete +contingency of phenomena. And the demonstration of this was the only +thing necessary for the solution of this apparent antinomy. For if +the condition of every conditioned--as regards its existence--is sensuous, +and for this reason a part of the same series, it must be itself +conditioned, as was shown in the antithesis of the fourth antinomy. +The embarrassments into which a reason, which postulates the +unconditioned, necessarily falls, must, therefore, continue to +exist; or the unconditioned must be placed in the sphere of the +intelligible. In this way, its necessity does not require, nor does +it even permit, the presence of an empirical condition: and it is, +consequently, unconditionally necessary. + +The empirical employment of reason is not affected by the assumption +of a purely intelligible being; it continues its operations on the +principle of the contingency of all phenomena, proceeding from +empirical conditions to still higher and higher conditions, themselves +empirical. Just as little does this regulative principle exclude the +assumption of an intelligible cause, when the question regards +merely the pure employment of reason--in relation to ends or aims. +For, in this case, an intelligible cause signifies merely the +transcendental and to us unknown ground of the possibility of sensuous +phenomena, and its existence, necessary and independent of all +sensuous conditions, is not inconsistent with the contingency of +phenomena, or with the unlimited possibility of regress which exists +in the series of empirical conditions. + + + +Concluding Remarks on the Antinomy of Pure Reason. + +So long as the object of our rational conceptions is the totality of +conditions in the world of phenomena, and the satisfaction, from +this source, of the requirements of reason, so long are our ideas +transcendental and cosmological. But when we set the unconditioned- +which is the aim of all our inquiries--in a sphere which lies out of +the world of sense and possible experience, our ideas become +transcendent. They are then not merely serviceable towards the +completion of the exercise of reason (which remains an idea, never +executed, but always to be pursued); they detach themselves completely +from experience and construct for themselves objects, the material +of which has not been presented by experience, and the objective +reality of which is not based upon the completion of the empirical +series, but upon pure a priori conceptions. The intelligible object +of these transcendent ideas may be conceded, as a transcendental +object. But we cannot cogitate it as a thing determinable by certain +distinct predicates relating to its internal nature, for it has no +connection with empirical conceptions; nor are we justified in +affirming the existence of any such object. It is, consequently, a +mere product of the mind alone. Of all the cosmological ideas, +however, it is that occasioning the fourth antinomy which compels us +to venture upon this step. For the existence of phenomena, always +conditioned and never self-subsistent, requires us to look for an +object different from phenomena--an intelligible object, with which +all contingency must cease. But, as we have allowed ourselves to +assume the existence of a self-subsistent reality out of the field +of experience, and are therefore obliged to regard phenomena as merely +a contingent mode of representing intelligible objects employed by +beings which are themselves intelligences--no other course remains +for us than to follow analogy and employ the same mode in forming +some conception of intelligible things, of which we have not the least +knowledge, which nature taught us to use in the formation of empirical +conceptions. Experience made us acquainted with the contingent. But +we are at present engaged in the discussion of things which are not +objects of experience; and must, therefore, deduce our knowledge of +them from that which is necessary absolutely and in itself, that is, +from pure conceptions. Hence the first step which we take out of the +world of sense obliges us to begin our system of new cognition with +the investigation of a necessary being, and to deduce from our +conceptions of it all our conceptions of intelligible things. This +we propose to attempt in the following chapter. + + + + +CHAPTER III. The Ideal of Pure Reason. + +SECTION I. Of the Ideal in General. + +We have seen that pure conceptions do not present objects to the +mind, except under sensuous conditions; because the conditions of +objective reality do not exist in these conceptions, which contain, +in fact, nothing but the mere form of thought. They may, however, when +applied to phenomena, be presented in concreto; for it is phenomena +that present to them the materials for the formation of empirical +conceptions, which are nothing more than concrete forms of the +conceptions of the understanding. But ideas are still further +removed from objective reality than categories; for no phenomenon +can ever present them to the human mind in concreto. They contain a +certain perfection, attainable by no possible empirical cognition; +and they give to reason a systematic unity, to which the unity of +experience attempts to approximate, but can never completely attain. + +But still further removed than the idea from objective reality is +the Ideal, by which term I understand the idea, not in concreto, but +in individuo--as an individual thing, determinable or determined by +the idea alone. The idea of humanity in its complete perfection +supposes not only the advancement of all the powers and faculties, +which constitute our conception of human nature, to a complete +attainment of their final aims, but also everything which is requisite +for the complete determination of the idea; for of all contradictory +predicates, only one can conform with the idea of the perfect man. +What I have termed an ideal was in Plato's philosophy an idea of the +divine mind--an individual object present to its pure intuition, the +most perfect of every kind of possible beings, and the archetype of +all phenomenal existences. + +Without rising to these speculative heights, we are bound to confess +that human reason contains not only ideas, but ideals, which +possess, not, like those of Plato, creative, but certainly practical +power--as regulative principles, and form the basis of the +perfectibility of certain actions. Moral conceptions are not perfectly +pure conceptions of reason, because an empirical element--of +pleasure or pain--lies at the foundation of them. In relation, +however, to the principle, whereby reason sets bounds to a freedom +which is in itself without law, and consequently when we attend merely +to their form, they may be considered as pure conceptions of reason. +Virtue and wisdom in their perfect purity are ideas. But the wise +man of the Stoics is an ideal, that is to say, a human being +existing only in thought and in complete conformity with the idea of +wisdom. As the idea provides a rule, so the ideal serves as an +archetype for the perfect and complete determination of the copy. Thus +the conduct of this wise and divine man serves us as a standard of +action, with which we may compare and judge ourselves, which may +help us to reform ourselves, although the perfection it demands can +never be attained by us. Although we cannot concede objective +reality to these ideals, they are not to be considered as chimeras; +on the contrary, they provide reason with a standard, which enables +it to estimate, by comparison, the degree of incompleteness in the +objects presented to it. But to aim at realizing the ideal in an example +in the world of experience--to describe, for instance, the character +of the perfectly wise man in a romance--is impracticable. Nay more, +there is something absurd in the attempt; and the result must be little +edifying, as the natural limitations, which are continually breaking +in upon the perfection and completeness of the idea, destroy the +illusion in the story and throw an air of suspicion even on what is +good in the idea, which hence appears fictitious and unreal. + +Such is the constitution of the ideal of reason, which is always +based upon determinate conceptions, and serves as a rule and a model +for limitation or of criticism. Very different is the nature of the +ideals of the imagination. Of these it is impossible to present an +intelligible conception; they are a kind of monogram, drawn +according to no determinate rule, and forming rather a vague +picture--the production of many diverse experiences--than a +determinate image. Such are the ideals which painters and +physiognomists profess to have in their minds, and which can serve +neither as a model for production nor as a standard for +appreciation. They may be termed, though improperly, sensuous +ideals, as they are declared to be models of certain possible +empirical intuitions. They cannot, however, furnish rules or standards +for explanation or examination. + +In its ideals, reason aims at complete and perfect determination +according to a priori rules; and hence it cogitates an object, which +must be completely determinable in conformity with principles, +although all empirical conditions are absent, and the conception of +the object is on this account transcendent. + + + +SECTION II. Of the Transcendental Ideal (Prototypon Trancendentale). + +Every conception is, in relation to that which is not contained in +it, undetermined and subject to the principle of determinability. This +principle is that, of every two contradictorily opposed predicates, +only one can belong to a conception. It is a purely logical principle, +itself based upon the principle of contradiction; inasmuch as it makes +complete abstraction of the content and attends merely to the +logical form of the cognition. + +But again, everything, as regards its possibility, is also subject +to the principle of complete determination, according to which one +of all the possible contradictory predicates of things must belong +to it. This principle is not based merely upon that of +contradiction; for, in addition to the relation between two +contradictory predicates, it regards everything as standing in a +relation to the sum of possibilities, as the sum total of all +predicates of things, and, while presupposing this sum as an a +priori condition, presents to the mind everything as receiving the +possibility of its individual existence from the relation it bears +to, and the share it possesses in, the aforesaid sum of possibilities.* +The principle of complete determination relates the content and not +to the logical form. It is the principle of the synthesis of all the +predicates which are required to constitute the complete conception +of a thing, and not a mere principle analytical representation, which +enounces that one of two contradictory predicates must belong to a +conception. It contains, moreover, a transcendental presupposition-- +that, namely, of the material for all possibility, which must +contain a priori the data for this or that particular possibility. + +[*Footnote: Thus this principle declares everything to possess a +relation to a common correlate--the sum-total of possibility, which, if +discovered to exist in the idea of one individual thing, would +establish the affinity of all possible things, from the identity of the +ground of their complete determination. The determinability of every +conception is subordinate to the universality (Allgemeinheit, +universalitas) of the principle of excluded middle; the determination +of a thing to the totality (Allheit, universitas) of all possible +predicates.] + +The proposition, everything which exists is completely determined, +means not only that one of every pair of given contradictory +attributes, but that one of all possible attributes, is always +predicable of the thing; in it the predicates are not merely +compared logically with each other, but the thing itself is +transcendentally compared with the sum-total of all possible +predicates. The proposition is equivalent to saying: "To attain to +a complete knowledge of a thing, it is necessary to possess a +knowledge of everything that is possible, and to determine it +thereby in a positive or negative manner." The conception of +complete determination is consequently a conception which cannot be +presented in its totality in concreto, and is therefore based upon +an idea, which has its seat in the reason--the faculty which +prescribes to the understanding the laws of its harmonious and perfect +exercise. + +Now, although this idea of the sum-total of all possibility, in so +far as it forms the condition of the complete determination of +everything, is itself undetermined in relation to the predicates which +may constitute this sum-total, and we cogitate in it merely the +sum-total of all possible predicates--we nevertheless find, upon +closer examination, that this idea, as a primitive conception of the +mind, excludes a large number of predicates--those deduced and those +irreconcilable with others, and that it is evolved as a conception +completely determined a priori. Thus it becomes the conception of an +individual object, which is completely determined by and through the +mere idea, and must consequently be termed an ideal of pure reason. + +When we consider all possible predicates, not merely logically, +but transcendentally, that is to say, with reference to the content +which may be cogitated as existing in them a priori, we shall find +that some indicate a being, others merely a non-being. The logical +negation expressed in the word not does not properly belong to a +conception, but only to the relation of one conception to another in +a judgement, and is consequently quite insufficient to present to the +mind the content of a conception. The expression not mortal does not +indicate that a non-being is cogitated in the object; it does not +concern the content at all. A transcendental negation, on the +contrary, indicates non-being in itself, and is opposed to +transcendental affirmation, the conception of which of itself +expresses a being. Hence this affirmation indicates a reality, because +in and through it objects are considered to be something--to be +things; while the opposite negation, on the other band, indicates a +mere want, or privation, or absence, and, where such negations alone +are attached to a representation, the non-existence of anything +corresponding to the representation. + +Now a negation cannot be cogitated as determined, without cogitating +at the same time the opposite affirmation. The man born blind has +not the least notion of darkness, because he has none of light; the +vagabond knows nothing of poverty, because he has never known what +it is to be in comfort;* the ignorant man has no conception of his +ignorance, because he has no conception of knowledge. All +conceptions of negatives are accordingly derived or deduced +conceptions; and realities contain the data, and, so to speak, the +material or transcendental content of the possibility and complete +determination of all things. + +[*Footnote: The investigations and calculations of astronomers have +taught us much that is wonderful; but the most important lesson we +have received from them is the discovery of the abyss of our ignorance +in relation to the universe--an ignorance the magnitude of which reason, +without the information thus derived, could never have conceived. This +discovery of our deficiencies must produce a great change in the +determination of the aims of human reason.] + +If, therefore, a transcendental substratum lies at the foundation of +the complete determination of things--a substratum which is to form +the fund from which all possible predicates of things are to be +supplied, this substratum cannot be anything else than the idea of +a sum-total of reality (omnitudo realitatis). In this view, negations +are nothing but limitations--a term which could not, with propriety, +be applied to them, if the unlimited (the all) did not form the true +basis of our conception. + +This conception of a sum-total of reality is the conception of a +thing in itself, regarded as completely determined; and the conception +of an ens realissimum is the conception of an individual being, +inasmuch as it is determined by that predicate of all possible +contradictory predicates, which indicates and belongs to being. It +is, therefore, a transcendental ideal which forms the basis of the +complete determination of everything that exists, and is the highest +material condition of its possibility--a condition on which must +rest the cogitation of all objects with respect to their content. Nay, +more, this ideal is the only proper ideal of which the human mind is +capable; because in this case alone a general conception of a thing +is completely determined by and through itself, and cognized as the +representation of an individuum. + +The logical determination of a conception is based upon a +disjunctive syllogism, the major of which contains the logical +division of the extent of a general conception, the minor limits +this extent to a certain part, while the conclusion determines the +conception by this part. The general conception of a reality cannot +be divided a priori, because, without the aid of experience, we cannot +know any determinate kinds of reality, standing under the former as +the genus. The transcendental principle of the complete +determination of all things is therefore merely the representation +of the sum-total of all reality; it is not a conception which is the +genus of all predicates under itself, but one which comprehends them +all within itself. The complete determination of a thing is +consequently based upon the limitation of this total of reality, so +much being predicated of the thing, while all that remains over is +excluded--a procedure which is in exact agreement with that of the +disjunctive syllogism and the determination of the objects in the +conclusion by one of the members of the division. It follows that +reason, in laying the transcendental ideal at the foundation of its +determination of all possible things, takes a course in exact +analogy with that which it pursues in disjunctive syllogisms--a +proposition which formed the basis of the systematic division of all +transcendental ideas, according to which they are produced in complete +parallelism with the three modes of syllogistic reasoning employed +by the human mind. + +It is self-evident that reason, in cogitating the necessary complete +determination of things, does not presuppose the existence of a +being corresponding to its ideal, but merely the idea of the ideal- +for the purpose of deducing from the unconditional totality of +complete determination, The ideal is therefore the prototype of all +things, which, as defective copies (ectypa), receive from it the +material of their possibility, and approximate to it more or less, +though it is impossible that they can ever attain to its perfection. + +The possibility of things must therefore be regarded as derived- +except that of the thing which contains in itself all reality, which +must be considered to be primitive and original. For all negations- +and they are the only predicates by means of which all other things +can be distinguished from the ens realissimum--are mere limitations +of a greater and a higher--nay, the highest reality; and they +consequently presuppose this reality, and are, as regards their +content, derived from it. The manifold nature of things is only an +infinitely various mode of limiting the conception of the highest +reality, which is their common substratum; just as all figures are +possible only as different modes of limiting infinite space. The +object of the ideal of reason--an object existing only in reason +itself--is also termed the primal being (ens originarium); as having +no existence superior to him, the supreme being (ens summum); and as +being the condition of all other beings, which rank under it, the +being of all beings (ens entium). But none of these terms indicate +the objective relation of an actually existing object to other things, +but merely that of an idea to conceptions; and all our investigations +into this subject still leave us in perfect uncertainty with regard +to the existence of this being. + +A primal being cannot be said to consist of many other beings with +an existence which is derivative, for the latter presuppose the +former, and therefore cannot be constitutive parts of it. It follows +that the ideal of the primal being must be cogitated as simple. + +The deduction of the possibility of all other things from this +primal being cannot, strictly speaking, be considered as a limitation, +or as a kind of division of its reality; for this would be regarding +the primal being as a mere aggregate--which has been shown to be +impossible, although it was so represented in our first rough +sketch. The highest reality must be regarded rather as the ground than +as the sum-total of the possibility of all things, and the manifold +nature of things be based, not upon the limitation of the primal being +itself, but upon the complete series of effects which flow from it. +And thus all our powers of sense, as well as all phenomenal reality, +phenomenal reality, may be with propriety regarded as belonging to +this series of effects, while they could not have formed parts of +the idea, considered as an aggregate. Pursuing this track, and +hypostatizing this idea, we shall find ourselves authorized to +determine our notion of the Supreme Being by means of the mere +conception of a highest reality, as one, simple, all-sufficient, +eternal, and so on--in one word, to determine it in its +unconditioned completeness by the aid of every possible predicate. +The conception of such a being is the conception of God in its +transcendental sense, and thus the ideal of pure reason is the +object-matter of a transcendental theology. + +But, by such an employment of the transcendental idea, we should +be over stepping the limits of its validity and purpose. For reason +placed it, as the conception of all reality, at the basis of the +complete determination of things, without requiring that this +conception be regarded as the conception of an objective existence. +Such an existence would be purely fictitious, and the hypostatizing +of the content of the idea into an ideal, as an individual being, is +a step perfectly unauthorized. Nay, more, we are not even called upon +to assume the possibility of such an hypothesis, as none of the +deductions drawn from such an ideal would affect the complete +determination of things in general--for the sake of which alone is +the idea necessary. + +It is not sufficient to circumscribe the procedure and the dialectic +of reason; we must also endeavour to discover the sources of this +dialectic, that we may have it in our power to give a rational +explanation of this illusion, as a phenomenon of the human mind. For +the ideal, of which we are at present speaking, is based, not upon +an arbitrary, but upon a natural, idea. The question hence arises: +How happens it that reason regards the possibility of all things as +deduced from a single possibility, that, to wit, of the highest +reality, and presupposes this as existing in an individual and +primal being? + +The answer is ready; it is at once presented by the procedure of +transcendental analytic. The possibility of sensuous objects is a +relation of these objects to thought, in which something (the +empirical form) may be cogitated a priori; while that which +constitutes the matter--the reality of the phenomenon (that element +which corresponds to sensation)--must be given from without, as +otherwise it could not even be cogitated by, nor could its possibility +be presentable to the mind. Now, a sensuous object is completely +determined, when it has been compared with all phenomenal +predicates, and represented by means of these either positively or +negatively. But, as that which constitutes the thing itself--the +real in a phenomenon, must be given, and that, in which the real of +all phenomena is given, is experience, one, sole, and all-embracing- +the material of the possibility of all sensuous objects must be +presupposed as given in a whole, and it is upon the limitation of this +whole that the possibility of all empirical objects, their distinction +from each other and their complete determination, are based. Now, no +other objects are presented to us besides sensuous objects, and +these can be given only in connection with a possible experience; it +follows that a thing is not an object to us, unless it presupposes +the whole or sum-total of empirical reality as the condition of its +possibility. Now, a natural illusion leads us to consider this +principle, which is valid only of sensuous objects, as valid with +regard to things in general. And thus we are induced to hold the +empirical principle of our conceptions of the possibility of things, +as phenomena, by leaving out this limitative condition, to be a +transcendental principle of the possibility of things in general. + +We proceed afterwards to hypostatize this idea of the sum-total of +all reality, by changing the distributive unity of the empirical +exercise of the understanding into the collective unity of an +empirical whole--a dialectical illusion, and by cogitating this +whole or sum of experience as an individual thing, containing in +itself all empirical reality. This individual thing or being is +then, by means of the above-mentioned transcendental subreption, +substituted for our notion of a thing which stands at the head of +the possibility of all things, the real conditions of whose complete +determination it presents.* + +[*Footnote: This ideal of the ens realissimum--although merely a mental +representation--is first objectivized, that is, has an objective +existence attributed to it, then hypostatized, and finally, by the +natural progress of reason to the completion of unity, personified, +as we shall show presently. For the regulative unity of experience +is not based upon phenomena themselves, but upon the connection of +the variety of phenomena by the understanding in a consciousness, and +thus the unity of the supreme reality and the complete determinability +of all things, seem to reside in a supreme understanding, and, +consequently, in a conscious intelligence.] + + + +SECTION III. Of the Arguments employed by Speculative Reason in + Proof of the Existence of a Supreme Being. + +Notwithstanding the pressing necessity which reason feels, to form +some presupposition that shall serve the understanding as a proper +basis for the complete determination of its conceptions, the +idealistic and factitious nature of such a presupposition is too +evident to allow reason for a moment to persuade itself into a +belief of the objective existence of a mere creation of its own +thought. But there are other considerations which compel reason to +seek out some resting place in the regress from the conditioned to +the unconditioned, which is not given as an actual existence from the +mere conception of it, although it alone can give completeness to the +series of conditions. And this is the natural course of every human +reason, even of the most uneducated, although the path at first +entered it does not always continue to follow. It does not begin +from conceptions, but from common experience, and requires a basis +in actual existence. But this basis is insecure, unless it rests +upon the immovable rock of the absolutely necessary. And this +foundation is itself unworthy of trust, if it leave under and above +it empty space, if it do not fill all, and leave no room for a why +or a wherefore, if it be not, in one word, infinite in its reality. + +If we admit the existence of some one thing, whatever it may be, +we must also admit that there is something which exists necessarily. +For what is contingent exists only under the condition of some other +thing, which is its cause; and from this we must go on to conclude +the existence of a cause which is not contingent, and which consequently +exists necessarily and unconditionally. Such is the argument by +which reason justifies its advances towards a primal being. + +Now reason looks round for the conception of a being that may be +admitted, without inconsistency, to be worthy of the attribute of +absolute necessity, not for the purpose of inferring a priori, from +the conception of such a being, its objective existence (for if reason +allowed itself to take this course, it would not require a basis in +given and actual existence, but merely the support of pure +conceptions), but for the purpose of discovering, among all our +conceptions of possible things, that conception which possesses no +element inconsistent with the idea of absolute necessity. For that +there must be some absolutely necessary existence, it regards as a +truth already established. Now, if it can remove every existence +incapable of supporting the attribute of absolute necessity, excepting +one--this must be the absolutely necessary being, whether its +necessity is comprehensible by us, that is, deducible from the +conception of it alone, or not. + +Now that, the conception of which contains a therefore to every +wherefore, which is not defective in any respect whatever, which is +all-sufficient as a condition, seems to be the being of which we can +justly predicate absolute necessity--for this reason, that, possessing +the conditions of all that is possible, it does not and cannot +itself require any condition. And thus it satisfies, in one respect +at least, the requirements of the conception of absolute necessity. +In this view, it is superior to all other conceptions, which, as +deficient and incomplete, do not possess the characteristic of +independence of all higher conditions. It is true that we cannot infer +from this that what does not contain in itself the supreme and +complete condition--the condition of all other things--must possess +only a conditioned existence; but as little can we assert the +contrary, for this supposed being does not possess the only +characteristic which can enable reason to cognize by means of an a +priori conception the unconditioned and necessary nature of its +existence. + +The conception of an ens realissimum is that which best agrees +with the conception of an unconditioned and necessary being. The +former conception does not satisfy all the requirements of the latter; +but we have no choice, we are obliged to adhere to it, for we find +that we cannot do without the existence of a necessary being; and even +although we admit it, we find it out of our power to discover in the +whole sphere of possibility any being that can advance well-grounded +claims to such a distinction. + +The following is, therefore, the natural course of human reason. +It begins by persuading itself of the existence of some necessary +being. In this being it recognizes the characteristics of +unconditioned existence. It then seeks the conception of that which +is independent of all conditions, and finds it in that which is itself +the sufficient condition of all other things--in other words, in +that which contains all reality. But the unlimited all is an +absolute unity, and is conceived by the mind as a being one and +supreme; and thus reason concludes that the Supreme Being, as the +primal basis of all things, possesses an existence which is absolutely +necessary. + +This conception must be regarded as in some degree satisfactory, +if we admit the existence of a necessary being, and consider that +there exists a necessity for a definite and final answer to these +questions. In such a case, we cannot make a better choice, or rather +we have no choice at all, but feel ourselves obliged to declare in +favour of the absolute unity of complete reality, as the highest +source of the possibility of things. But if there exists no motive +for coming to a definite conclusion, and we may leave the question +unanswered till we have fully weighed both sides--in other words, when +we are merely called upon to decide how much we happen to know about +the question, and how much we merely flatter ourselves that we know- +the above conclusion does not appear to be so great advantage, but, +on the contrary, seems defective in the grounds upon which it is +supported. + +For, admitting the truth of all that has been said, that, namely, +the inference from a given existence (my own, for example) to the +existence of an unconditioned and necessary being is valid and +unassailable; that, in the second place, we must consider a being +which contains all reality, and consequently all the conditions of +other things, to be absolutely unconditioned; and admitting too, +that we have thus discovered the conception of a thing to which may +be attributed, without inconsistency, absolute necessity--it does not +follow from all this that the conception of a limited being, in +which the supreme reality does not reside, is therefore incompatible +with the idea of absolute necessity. For, although I do not discover +the element of the unconditioned in the conception of such a being--an +element which is manifestly existent in the sum-total of all +conditions--I am not entitled to conclude that its existence is +therefore conditioned; just as I am not entitled to affirm, in a +hypothetical syllogism, that where a certain condition does not +exist (in the present, completeness, as far as pure conceptions are +concerned), the conditioned does not exist either. On the contrary, +we are free to consider all limited beings as likewise unconditionally +necessary, although we are unable to infer this from the general +conception which we have of them. Thus conducted, this argument is +incapable of giving us the least notion of the properties of a +necessary being, and must be in every respect without result. + +This argument continues, however, to possess a weight and an +authority, which, in spite of its objective insufficiency, it has +never been divested of. For, granting that certain responsibilities +lie upon us, which, as based on the ideas of reason, deserve to be +respected and submitted to, although they are incapable of a real or +practical application to our nature, or, in other words, would be +responsibilities without motives, except upon the supposition of a +Supreme Being to give effect and influence to the practical laws: in +such a case we should be bound to obey our conceptions, which, +although objectively insufficient, do, according to the standard of +reason, preponderate over and are superior to any claims that may be +advanced from any other quarter. The equilibrium of doubt would in +this case be destroyed by a practical addition; indeed, Reason would +be compelled to condemn herself, if she refused to comply with the +demands of the judgement, no superior to which we know--however +defective her understanding of the grounds of these demands might be. + +This argument, although in fact transcendental, inasmuch as it rests +upon the intrinsic insufficiency of the contingent, is so simple and +natural, that the commonest understanding can appreciate its value. +We see things around us change, arise, and pass away; they, or their +condition, must therefore have a cause. The same demand must again +be made of the cause itself--as a datum of experience. Now it is +natural that we should place the highest causality just where we place +supreme causality, in that being, which contains the conditions of +all possible effects, and the conception of which is so simple as that +of an all-embracing reality. This highest cause, then, we regard as +absolutely necessary, because we find it absolutely necessary to +rise to it, and do not discover any reason for proceeding beyond it. +Thus, among all nations, through the darkest polytheism glimmer some +faint sparks of monotheism, to which these idolaters have been led, +not from reflection and profound thought, but by the study and natural +progress of the common understanding. + +There are only three modes of proving the existence of a Deity, on +the grounds of speculative reason. + +All the paths conducting to this end begin either from determinate +experience and the peculiar constitution of the world of sense, and +rise, according to the laws of causality, from it to the highest cause +existing apart from the world--or from a purely indeterminate +experience, that is, some empirical existence--or abstraction is +made of all experience, and the existence of a supreme cause is +concluded from a priori conceptions alone. The first is the +physico-theological argument, the second the cosmological, the third +the ontological. More there are not, and more there cannot be. + +I shall show it is as unsuccessful on the one path--the empirical- +as on the other--the transcendental, and that it stretches its wings +in vain, to soar beyond the world of sense by the mere might of +speculative thought. As regards the order in which we must discuss +those arguments, it will be exactly the reverse of that in which +reason, in the progress of its development, attains to them--the order +in which they are placed above. For it will be made manifest to the +reader that, although experience presents the occasion and the +starting-point, it is the transcendental idea of reason which guides +it in its pilgrimage and is the goal of all its struggles. I shall +therefore begin with an examination of the transcendental argument, +and afterwards inquire what additional strength has accrued to this +mode of proof from the addition of the empirical element. + + + +SECTION IV. Of the Impossibility of an Ontological Proof of + the Existence of God. + +It is evident from what has been said that the conception of an +absolutely necessary being is a mere idea, the objective reality of +which is far from being established by the mere fact that it is a need +of reason. On the contrary, this idea serves merely to indicate a +certain unattainable perfection, and rather limits the operations +than, by the presentation of new objects, extends the sphere of the +understanding. But a strange anomaly meets us at the very threshold; +for the inference from a given existence in general to an absolutely +necessary existence seems to be correct and unavoidable, while the +conditions of the understanding refuse to aid us in forming any +conception of such a being. + +Philosophers have always talked of an absolutely necessary being, +and have nevertheless declined to take the trouble of conceiving +whether--and how--a being of this nature is even cogitable, not to +mention that its existence is actually demonstrable. A verbal +definition of the conception is certainly easy enough: it is something +the non-existence of which is impossible. But does this definition +throw any light upon the conditions which render it impossible to +cogitate the non-existence of a thing--conditions which we wish to +ascertain, that we may discover whether we think anything in the +conception of such a being or not? For the mere fact that I throw +away, by means of the word unconditioned, all the conditions which +the understanding habitually requires in order to regard anything as +necessary, is very far from making clear whether by means of the +conception of the unconditionally necessary I think of something, or +really of nothing at all. + +Nay, more, this chance-conception, now become so current, many +have endeavoured to explain by examples which seemed to render any +inquiries regarding its intelligibility quite needless. Every +geometrical proposition--a triangle has three angles--it was said, +is absolutely necessary; and thus people talked of an object which +lay out of the sphere of our understanding as if it were perfectly +plain what the conception of such a being meant. + +All the examples adduced have been drawn, without exception, from +judgements, and not from things. But the unconditioned necessity of +a judgement does not form the absolute necessity of a thing. On the +contrary, the absolute necessity of a judgement is only a +conditioned necessity of a thing, or of the predicate in a +judgement. The proposition above-mentioned does not enounce that three +angles necessarily exist, but, upon condition that a triangle +exists, three angles must necessarily exist--in it. And thus this +logical necessity has been the source of the greatest delusions. +Having formed an a priori conception of a thing, the content of +which was made to embrace existence, we believed ourselves safe in +concluding that, because existence belongs necessarily to the object +of the conception (that is, under the condition of my positing this +thing as given), the existence of the thing is also posited +necessarily, and that it is therefore absolutely necessary--merely +because its existence has been cogitated in the conception. + +If, in an identical judgement, I annihilate the predicate in +thought, and retain the subject, a contradiction is the result; and +hence I say, the former belongs necessarily to the latter. But if I +suppress both subject and predicate in thought, no contradiction +arises; for there is nothing at all, and therefore no means of forming +a contradiction. To suppose the existence of a triangle and not that +of its three angles, is self-contradictory; but to suppose the +non-existence of both triangle and angles is perfectly admissible. +And so is it with the conception of an absolutely necessary being. +Annihilate its existence in thought, and you annihilate the thing +itself with all its predicates; how then can there be any room for +contradiction? Externally, there is nothing to give rise to a +contradiction, for a thing cannot be necessary externally; nor +internally, for, by the annihilation or suppression of the thing +itself, its internal properties are also annihilated. God is +omnipotent--that is a necessary judgement. His omnipotence cannot be +denied, if the existence of a Deity is posited--the existence, that +is, of an infinite being, the two conceptions being identical. But +when you say, God does not exist, neither omnipotence nor any other +predicate is affirmed; they must all disappear with the subject, and +in this judgement there cannot exist the least self-contradiction. + +You have thus seen that when the predicate of a judgement is +annihilated in thought along with the subject, no internal +contradiction can arise, be the predicate what it may. There is no +possibility of evading the conclusion--you find yourselves compelled +to declare: There are certain subjects which cannot be annihilated +in thought. But this is nothing more than saying: There exist subjects +which are absolutely necessary--the very hypothesis which you are +called upon to establish. For I find myself unable to form the +slightest conception of a thing which when annihilated in thought with +all its predicates, leaves behind a contradiction; and contradiction +is the only criterion of impossibility in the sphere of pure a +priori conceptions. + +Against these general considerations, the justice of which no one +can dispute, one argument is adduced, which is regarded as +furnishing a satisfactory demonstration from the fact. It is +affirmed that there is one and only one conception, in which the +non-being or annihilation of the object is self-contradictory, and +this is the conception of an ens realissimum. It possesses, you say, +all reality, and you feel yourselves justified in admitting the +possibility of such a being. (This I am willing to grant for the +present, although the existence of a conception which is not +self-contradictory is far from being sufficient to prove the +possibility of an object.)* Now the notion of all reality embraces +in it that of existence; the notion of existence lies, therefore, in +the conception of this possible thing. If this thing is annihilated +in thought, the internal possibility of the thing is also annihilated, +which is self-contradictory. + +[*Footnote: A conception is always possible, if it is not +self-contradictory. This is the logical criterion of possibility, +distinguishing the object of such a conception from the nihil negativum. +But it may be, notwithstanding, an empty conception, unless the objective +reality of this synthesis, but which it is generated, is demonstrated; +and a proof of this kind must be based upon principles of possible +experience, and not upon the principle of analysis or contradiction. +This remark may be serviceable as a warning against concluding, from +the possibility of a conception--which is logical--the possibility +of a thing--which is real.] + +I answer: It is absurd to introduce--under whatever term +disguised--into the conception of a thing, which is to be cogitated +solely in reference to its possibility, the conception of its +existence. If this is admitted, you will have apparently gained the +day, but in reality have enounced nothing but a mere tautology. I ask, +is the proposition, this or that thing (which I am admitting to be +possible) exists, an analytical or a synthetical proposition? If the +former, there is no addition made to the subject of your thought by +the affirmation of its existence; but then the conception in your +minds is identical with the thing itself, or you have supposed the +existence of a thing to be possible, and then inferred its existence +from its internal possibility--which is but a miserable tautology. +The word reality in the conception of the thing, and the word existence +in the conception of the predicate, will not help you out of the +difficulty. For, supposing you were to term all positing of a thing +reality, you have thereby posited the thing with all its predicates +in the conception of the subject and assumed its actual existence, +and this you merely repeat in the predicate. But if you confess, as +every reasonable person must, that every existential proposition is +synthetical, how can it be maintained that the predicate of +existence cannot be denied without contradiction?--a property which +is the characteristic of analytical propositions, alone. + +I should have a reasonable hope of putting an end for ever to this +sophistical mode of argumentation, by a strict definition of the +conception of existence, did not my own experience teach me that the +illusion arising from our confounding a logical with a real +predicate (a predicate which aids in the determination of a thing) +resists almost all the endeavours of explanation and illustration. +A logical predicate may be what you please, even the subject may be +predicated of itself; for logic pays no regard to the content of a +judgement. But the determination of a conception is a predicate, which +adds to and enlarges the conception. It must not, therefore, be +contained in the conception. + +Being is evidently not a real predicate, that is, a conception of +something which is added to the conception of some other thing. It +is merely the positing of a thing, or of certain determinations in +it. Logically, it is merely the copula of a judgement. The proposition, +God is omnipotent, contains two conceptions, which have a certain +object or content; the word is, is no additional predicate--it +merely indicates the relation of the predicate to the subject. Now, +if I take the subject (God) with all its predicates (omnipotence being +one), and say: God is, or, There is a God, I add no new predicate to +the conception of God, I merely posit or affirm the existence of the +subject with all its predicates--I posit the object in relation to +my conception. The content of both is the same; and there is no +addition made to the conception, which expresses merely the +possibility of the object, by my cogitating the object--in the +expression, it is--as absolutely given or existing. Thus the real +contains no more than the possible. A hundred real dollars contain +no more than a hundred possible dollars. For, as the latter indicate +the conception, and the former the object, on the supposition that +the content of the former was greater than that of the latter, my +conception would not be an expression of the whole object, and would +consequently be an inadequate conception of it. But in reckoning my +wealth there may be said to be more in a hundred real dollars than +in a hundred possible dollars--that is, in the mere conception of +them. For the real object--the dollars--is not analytically +contained in my conception, but forms a synthetical addition to my +conception (which is merely a determination of my mental state), +although this objective reality--this existence--apart from my +conceptions, does not in the least degree increase the aforesaid +hundred dollars. + +By whatever and by whatever number of predicates--even to the +complete determination of it--I may cogitate a thing, I do not in +the least augment the object of my conception by the addition of the +statement: This thing exists. Otherwise, not exactly the same, but +something more than what was cogitated in my conception, would +exist, and I could not affirm that the exact object of my conception +had real existence. If I cogitate a thing as containing all modes of +reality except one, the mode of reality which is absent is not added +to the conception of the thing by the affirmation that the thing +exists; on the contrary, the thing exists--if it exist at all--with +the same defect as that cogitated in its conception; otherwise not +that which was cogitated, but something different, exists. Now, if +I cogitate a being as the highest reality, without defect or +imperfection, the question still remains--whether this being exists +or not? For, although no element is wanting in the possible real +content of my conception, there is a defect in its relation to my +mental state, that is, I am ignorant whether the cognition of the +object indicated by the conception is possible a posteriori. And +here the cause of the present difficulty becomes apparent. If the +question regarded an object of sense merely, it would be impossible +for me to confound the conception with the existence of a thing. For +the conception merely enables me to cogitate an object as according +with the general conditions of experience; while the existence of +the object permits me to cogitate it as contained in the sphere of +actual experience. At the same time, this connection with the world +of experience does not in the least augment the conception, although +a possible perception has been added to the experience of the mind. +But if we cogitate existence by the pure category alone, it is not +to be wondered at, that we should find ourselves unable to present +any criterion sufficient to distinguish it from mere possibility. + +Whatever be the content of our conception of an object, it is +necessary to go beyond it, if we wish to predicate existence of the +object. In the case of sensuous objects, this is attained by their +connection according to empirical laws with some one of my +perceptions; but there is no means of cognizing the existence of +objects of pure thought, because it must be cognized completely a +priori. But all our knowledge of existence (be it immediately by +perception, or by inferences connecting some object with a perception) +belongs entirely to the sphere of experience--which is in perfect +unity with itself; and although an existence out of this sphere cannot +be absolutely declared to be impossible, it is a hypothesis the +truth of which we have no means of ascertaining. + +The notion of a Supreme Being is in many respects a highly useful +idea; but for the very reason that it is an idea, it is incapable of +enlarging our cognition with regard to the existence of things. It +is not even sufficient to instruct us as to the possibility of a being +which we do not know to exist. The analytical criterion of +possibility, which consists in the absence of contradiction in +propositions, cannot be denied it. But the connection of real +properties in a thing is a synthesis of the possibility of which an +a priori judgement cannot be formed, because these realities are not +presented to us specifically; and even if this were to happen, a +judgement would still be impossible, because the criterion of the +possibility of synthetical cognitions must be sought for in the +world of experience, to which the object of an idea cannot belong. +And thus the celebrated Leibnitz has utterly failed in his attempt +to establish upon a priori grounds the possibility of this sublime +ideal being. + +The celebrated ontological or Cartesian argument for the existence +of a Supreme Being is therefore insufficient; and we may as well +hope to increase our stock of knowledge by the aid of mere ideas, as +the merchant to augment his wealth by the addition of noughts to his +cash account. + + + +SECTION V. Of the Impossibility of a Cosmological Proof + of the Existence of God. + +It was by no means a natural course of proceeding, but, on the +contrary, an invention entirely due to the subtlety of the schools, +to attempt to draw from a mere idea a proof of the existence of an +object corresponding to it. Such a course would never have been pursued, +were it not for that need of reason which requires it to suppose the +existence of a necessary being as a basis for the empirical regress, +and that, as this necessity must be unconditioned and a priori, reason +is bound to discover a conception which shall satisfy, if possible, +this requirement, and enable us to attain to the a priori cognition +of such a being. This conception was thought to be found in the idea +of an ens realissimum, and thus this idea was employed for the attainment +of a better defined knowledge of a necessary being, of the existence +of which we were convinced, or persuaded, on other grounds. Thus +reason was seduced from her natural courage; and, instead of +concluding with the conception of an ens realissimum, an attempt was +made to begin with it, for the purpose of inferring from it that +idea of a necessary existence which it was in fact called in to +complete. Thus arose that unfortunate ontological argument, which +neither satisfies the healthy common sense of humanity, nor sustains +the scientific examination of the philosopher. + +The cosmological proof, which we are about to examine, retains the +connection between absolute necessity and the highest reality; but, +instead of reasoning from this highest reality to a necessary +existence, like the preceding argument, it concludes from the given +unconditioned necessity of some being its unlimited reality. The track +it pursues, whether rational or sophistical, is at least natural, +and not only goes far to persuade the common understanding, but +shows itself deserving of respect from the speculative intellect; +while it contains, at the same time, the outlines of all the arguments +employed in natural theology--arguments which always have been, and +still will be, in use and authority. These, however adorned, and hid +under whatever embellishments of rhetoric and sentiment, are at bottom +identical with the arguments we are at present to discuss. This proof, +termed by Leibnitz the argumentum a contingentia mundi, I shall now +lay before the reader, and subject to a strict examination. + +It is framed in the following manner: If something exists, an +absolutely necessary being must likewise exist. Now I, at least, +exist. Consequently, there exists an absolutely necessary being. The +minor contains an experience, the major reasons from a general +experience to the existence of a necessary being.* Thus this +argument really begins at experience, and is not completely a +priori, or ontological. The object of all possible experience being +the world, it is called the cosmological proof. It contains no +reference to any peculiar property of sensuous objects, by which +this world of sense might be distinguished from other possible worlds; +and in this respect it differs from the physico-theological proof, +which is based upon the consideration of the peculiar constitution +of our sensuous world. + +[*Footnote: This inference is too well known to require more detailed +discussion. It is based upon the spurious transcendental law of +causality, that everything which is contingent has a cause, which, +if itself contingent, must also have a cause; and so on, till the +series of subordinated causes must end with an absolutely necessary +cause, without which it would not possess completeness.] + +The proof proceeds thus: A necessary being can be determined only in +one way, that is, it can be determined by only one of all possible +opposed predicates; consequently, it must be completely determined +in and by its conception. But there is only a single conception of +a thing possible, which completely determines the thing a priori: that +is, the conception of the ens realissimum. It follows that the +conception of the ens realissimum is the only conception by and in +which we can cogitate a necessary being. Consequently, a Supreme Being +necessarily exists. + +In this cosmological argument are assembled so many sophistical +propositions that speculative reason seems to have exerted in it all +her dialectical skill to produce a transcendental illusion of the most +extreme character. We shall postpone an investigation of this argument +for the present, and confine ourselves to exposing the stratagem by +which it imposes upon us an old argument in a new dress, and appeals +to the agreement of two witnesses, the one with the credentials of +pure reason, and the other with those of empiricism; while, in fact, +it is only the former who has changed his dress and voice, for the +purpose of passing himself off for an additional witness. That it +may possess a secure foundation, it bases its conclusions upon +experience, and thus appears to be completely distinct from the +ontological argument, which places its confidence entirely in pure +a priori conceptions. But this experience merely aids reason in making +one step--to the existence of a necessary being. What the properties +of this being are cannot be learned from experience; and therefore +reason abandons it altogether, and pursues its inquiries in the sphere +of pure conception, for the purpose of discovering what the properties +of an absolutely necessary being ought to be, that is, what among +all possible things contain the conditions (requisita) of absolute +necessity. Reason believes that it has discovered these requisites +in the conception of an ens realissimum--and in it alone, and hence +concludes: The ens realissimum is an absolutely necessary being. But +it is evident that reason has here presupposed that the conception +of an ens realissimum is perfectly adequate to the conception of a +being of absolute necessity, that is, that we may infer the +existence of the latter from that of the former--a proposition which +formed the basis of the ontological argument, and which is now +employed in the support of the cosmological argument, contrary to +the wish and professions of its inventors. For the existence of an +absolutely necessary being is given in conceptions alone. But if I +say: "The conception of the ens realissimum is a conception of this +kind, and in fact the only conception which is adequate to our idea +of a necessary being," I am obliged to admit, that the latter may be +inferred from the former. Thus it is properly the ontological argument +which figures in the cosmological, and constitutes the whole +strength of the latter; while the spurious basis of experience has +been of no further use than to conduct us to the conception of +absolute necessity, being utterly insufficient to demonstrate the +presence of this attribute in any determinate existence or thing. +For when we propose to ourselves an aim of this character, we must +abandon the sphere of experience, and rise to that of pure +conceptions, which we examine with the purpose of discovering +whether any one contains the conditions of the possibility of an +absolutely necessary being. But if the possibility of such a being +is thus demonstrated, its existence is also proved; for we may then +assert that, of all possible beings there is one which possesses the +attribute of necessity--in other words, this being possesses an +absolutely necessary existence. + +All illusions in an argument are more easily detected when they +are presented in the formal manner employed by the schools, which we +now proceed to do. + +If the proposition: "Every absolutely necessary being is likewise an +ens realissimum," is correct (and it is this which constitutes the +nervus probandi of the cosmological argument), it must, like all +affirmative judgements, be capable of conversion--the conversio per +accidens, at least. It follows, then, that some entia realissima are +absolutely necessary beings. But no ens realissimum is in any +respect different from another, and what is valid of some is valid +of all. In this present case, therefore, I may employ simple +conversion, and say: "Every ens realissimum is a necessary being." +But as this proposition is determined a priori by the conceptions +contained in it, the mere conception of an ens realissimum must +possess the additional attribute of absolute necessity. But this is +exactly what was maintained in the ontological argument, and not +recognized by the cosmological, although it formed the real ground +of its disguised and illusory reasoning. + +Thus the second mode employed by speculative reason of demonstrating +the existence of a Supreme Being, is not only, like the first, +illusory and inadequate, but possesses the additional blemish of an +ignoratio elenchi--professing to conduct us by a new road to the +desired goal, but bringing us back, after a short circuit, to the +old path which we had deserted at its call. + +I mentioned above that this cosmological argument contains a perfect +nest of dialectical assumptions, which transcendental criticism does +not find it difficult to expose and to dissipate. I shall merely +enumerate these, leaving it to the reader, who must by this time be +well practised in such matters, to investigate the fallacies +residing therein. + +The following fallacies, for example, are discoverable in this +mode of proof: 1. The transcendental principle: "Everything that is +contingent must have a cause"--a principle without significance, +except in the sensuous world. For the purely intellectual conception +of the contingent cannot produce any synthetical proposition, like +that of causality, which is itself without significance or +distinguishing characteristic except in the phenomenal world. But in +the present case it is employed to help us beyond the limits of its +sphere. 2. "From the impossibility of an infinite ascending series +of causes in the world of sense a first cause is inferred"; a +conclusion which the principles of the employment of reason do not +justify even in the sphere of experience, and still less when an +attempt is made to pass the limits of this sphere. 3. Reason allows +itself to be satisfied upon insufficient grounds, with regard to the +completion of this series. It removes all conditions (without which, +however, no conception of Necessity can take place); and, as after +this it is beyond our power to form any other conceptions, it +accepts this as a completion of the conception it wishes to form of +the series. 4. The logical possibility of a conception of the total +of reality (the criterion of this possibility being the absence of +contradiction) is confounded with the transcendental, which requires +a principle of the practicability of such a synthesis--a principle +which again refers us to the world of experience. And so on. + +The aim of the cosmological argument is to avoid the necessity of +proving the existence of a necessary being priori from mere +conceptions--a proof which must be ontological, and of which we feel +ourselves quite incapable. With this purpose, we reason from an actual +existence--an experience in general, to an absolutely necessary +condition of that existence. It is in this case unnecessary to +demonstrate its possibility. For after having proved that it exists, +the question regarding its possibility is superfluous. Now, when we +wish to define more strictly the nature of this necessary being, we +do not look out for some being the conception of which would enable +us to comprehend the necessity of its being--for if we could do this, +an empirical presupposition would be unnecessary; no, we try to +discover merely the negative condition (conditio sine qua non), +without which a being would not be absolutely necessary. Now this +would be perfectly admissible in every sort of reasoning, from a +consequence to its principle; but in the present case it unfortunately +happens that the condition of absolute necessity can be discovered +in but a single being, the conception of which must consequently +contain all that is requisite for demonstrating the presence of +absolute necessity, and thus entitle me to infer this absolute +necessity a priori. That is, it must be possible to reason conversely, +and say: The thing, to which the conception of the highest reality +belongs, is absolutely necessary. But if I cannot reason thus--and +I cannot, unless I believe in the sufficiency of the ontological +argument--I find insurmountable obstacles in my new path, and am +really no farther than the point from which I set out. The +conception of a Supreme Being satisfies all questions a priori +regarding the internal determinations of a thing, and is for this +reason an ideal without equal or parallel, the general conception of +it indicating it as at the same time an ens individuum among all +possible things. But the conception does not satisfy the question +regarding its existence--which was the purpose of all our inquiries; +and, although the existence of a necessary being were admitted, we +should find it impossible to answer the question: What of all things +in the world must be regarded as such? + +It is certainly allowable to admit the existence of an +all-sufficient being--a cause of all possible effects--for the purpose +of enabling reason to introduce unity into its mode and grounds of +explanation with regard to phenomena. But to assert that such a +being necessarily exists, is no longer the modest enunciation of an +admissible hypothesis, but the boldest declaration of an apodeictic +certainty; for the cognition of that which is absolutely necessary +must itself possess that character. + +The aim of the transcendental ideal formed by the mind is either +to discover a conception which shall harmonize with the idea of +absolute necessity, or a conception which shall contain that idea. +If the one is possible, so is the other; for reason recognizes that +alone as absolutely necessary which is necessary from its +conception. But both attempts are equally beyond our power--we find +it impossible to satisfy the understanding upon this point, and as +impossible to induce it to remain at rest in relation to this +incapacity. + +Unconditioned necessity, which, as the ultimate support and stay +of all existing things, is an indispensable requirement of the mind, +is an abyss on the verge of which human reason trembles in dismay. +Even the idea of eternity, terrible and sublime as it is, as +depicted by Haller, does not produce upon the mental vision such a +feeling of awe and terror; for, although it measures the duration of +things, it does not support them. We cannot bear, nor can we rid +ourselves of the thought that a being, which we regard as the greatest +of all possible existences, should say to himself: I am from +eternity to eternity; beside me there is nothing, except that which +exists by my will; whence then am I? Here all sinks away from under +us; and the greatest, as the smallest, perfection, hovers without stay +or footing in presence of the speculative reason, which finds it as +easy to part with the one as with the other. + +Many physical powers, which evidence their existence by their +effects, are perfectly inscrutable in their nature; they elude all +our powers of observation. The transcendental object which forms the +basis of phenomena, and, in connection with it, the reason why our +sensibility possesses this rather than that particular kind of +conditions, are and must ever remain hidden from our mental vision; +the fact is there, the reason of the fact we cannot see. But an +ideal of pure reason cannot be termed mysterious or inscrutable, +because the only credential of its reality is the need of it felt by +reason, for the purpose of giving completeness to the world of +synthetical unity. An ideal is not even given as a cogitable object, +and therefore cannot be inscrutable; on the contrary, it must, as a +mere idea, be based on the constitution of reason itself, and on +this account must be capable of explanation and solution. For the very +essence of reason consists in its ability to give an account, of all +our conceptions, opinions, and assertions--upon objective, or, when +they happen to be illusory and fallacious, upon subjective grounds. + + + +Detection and Explanation of the Dialectical Illusion in +all Transcendental Arguments for the Existence of a +Necessary Being. + +Both of the above arguments are transcendental; in other words, they +do not proceed upon empirical principles. For, although the +cosmological argument professed to lay a basis of experience for its +edifice of reasoning, it did not ground its procedure upon the +peculiar constitution of experience, but upon pure principles of +reason--in relation to an existence given by empirical +consciousness; utterly abandoning its guidance, however, for the +purpose of supporting its assertions entirely upon pure conceptions. +Now what is the cause, in these transcendental arguments, of the +dialectical, but natural, illusion, which connects the conceptions +of necessity and supreme reality, and hypostatizes that which cannot +be anything but an idea? What is the cause of this unavoidable step +on the part of reason, of admitting that some one among all existing +things must be necessary, while it falls back from the assertion of +the existence of such a being as from an abyss? And how does reason +proceed to explain this anomaly to itself, and from the wavering +condition of a timid and reluctant approbation--always again +withdrawn--arrive at a calm and settled insight into its cause? + +It is something very remarkable that, on the supposition that +something exists, I cannot avoid the inference that something exists +necessarily. Upon this perfectly natural--but not on that account +reliable--inference does the cosmological argument rest. But, let me +form any conception whatever of a thing, I find that I cannot cogitate +the existence of the thing as absolutely necessary, and that nothing +prevents me--be the thing or being what it may--from cogitating its +non-existence. I may thus be obliged to admit that all existing things +have a necessary basis, while I cannot cogitate any single or +individual thing as necessary. In other words, I can never complete +the regress through the conditions of existence, without admitting +the existence of a necessary being; but, on the other hand, I cannot +make a commencement from this being. + +If I must cogitate something as existing necessarily as the basis of +existing things, and yet am not permitted to cogitate any individual +thing as in itself necessary, the inevitable inference is that +necessity and contingency are not properties of things themselves- +otherwise an internal contradiction would result; that consequently +neither of these principles are objective, but merely subjective +principles of reason--the one requiring us to seek for a necessary +ground for everything that exists, that is, to be satisfied with no +other explanation than that which is complete a priori, the other +forbidding us ever to hope for the attainment of this completeness, +that is, to regard no member of the empirical world as +unconditioned. In this mode of viewing them, both principles, in their +purely heuristic and regulative character, and as concerning merely +the formal interest of reason, are quite consistent with each other. +The one says: "You must philosophize upon nature," as if there existed +a necessary primal basis of all existing things, solely for the +purpose of introducing systematic unity into your knowledge, by +pursuing an idea of this character--a foundation which is +arbitrarily admitted to be ultimate; while the other warns you to +consider no individual determination, concerning the existence of +things, as such an ultimate foundation, that is, as absolutely +necessary, but to keep the way always open for further progress in +the deduction, and to treat every determination as determined by some +other. But if all that we perceive must be regarded as conditionally +necessary, it is impossible that anything which is empirically given +should be absolutely necessary. + +It follows from this that you must accept the absolutely necessary +as out of and beyond the world, inasmuch as it is useful only as a +principle of the highest possible unity in experience, and you +cannot discover any such necessary existence in the would, the +second rule requiring you to regard all empirical causes of unity as +themselves deduced. + +The philosophers of antiquity regarded all the forms of nature as +contingent; while matter was considered by them, in accordance with +the judgement of the common reason of mankind, as primal and +necessary. But if they had regarded matter, not relatively--as the +substratum of phenomena, but absolutely and in itself--as an +independent existence, this idea of absolute necessity would have +immediately disappeared. For there is nothing absolutely connecting +reason with such an existence; on the contrary, it can annihilate it +in thought, always and without self-contradiction. But in thought +alone lay the idea of absolute necessity. A regulative principle must, +therefore, have been at the foundation of this opinion. In fact, +extension and impenetrability--which together constitute our +conception of matter--form the supreme empirical principle of the +unity of phenomena, and this principle, in so far as it is empirically +unconditioned, possesses the property of a regulative principle. +But, as every determination of matter which constitutes what is real +in it--and consequently impenetrability--is an effect, which must have +a cause, and is for this reason always derived, the notion of matter +cannot harmonize with the idea of a necessary being, in its +character of the principle of all derived unity. For every one of +its real properties, being derived, must be only conditionally +necessary, and can therefore be annihilated in thought; and thus the +whole existence of matter can be so annihilated or suppressed. If this +were not the case, we should have found in the world of phenomena +the highest ground or condition of unity--which is impossible, +according to the second regulative principle. It follows that +matter, and, in general, all that forms part of the world of sense, +cannot be a necessary primal being, nor even a principle of +empirical unity, but that this being or principle must have its +place assigned without the world. And, in this way, we can proceed +in perfect confidence to deduce the phenomena of the world and their +existence from other phenomena, just as if there existed no +necessary being; and we can at the same time, strive without ceasing +towards the attainment of completeness for our deduction, just as if +such a being--the supreme condition of all existences--were +presupposed by the mind. + +These remarks will have made it evident to the reader that the ideal +of the Supreme Being, far from being an enouncement of the existence +of a being in itself necessary, is nothing more than a regulative +principle of reason, requiring us to regard all connection existing +between phenomena as if it had its origin from an all-sufficient +necessary cause, and basing upon this the rule of a systematic and +necessary unity in the explanation of phenomena. We cannot, at the +same time, avoid regarding, by a transcendental subreptio, this formal +principle as constitutive, and hypostatizing this unity. Precisely +similar is the case with our notion of space. Space is the primal +condition of all forms, which are properly just so many different +limitations of it; and thus, although it is merely a principle of +sensibility, we cannot help regarding it as an absolutely necessary +and self-subsistent thing--as an object given a priori in itself. In +the same way, it is quite natural that, as the systematic unity of +nature cannot be established as a principle for the empirical +employment of reason, unless it is based upon the idea of an ens +realissimum, as the supreme cause, we should regard this idea as a +real object, and this object, in its character of supreme condition, +as absolutely necessary, and that in this way a regulative should be +transformed into a constitutive principle. This interchange becomes +evident when I regard this supreme being, which, relatively to the +world, was absolutely (unconditionally) necessary, as a thing per +se. In this case, I find it impossible to represent this necessity +in or by any conception, and it exists merely in my own mind, as the +formal condition of thought, but not as a material and hypostatic +condition of existence. + + + +SECTION VI. Of the Impossibility of a Physico-Theological Proof. + +If, then, neither a pure conception nor the general experience of an +existing being can provide a sufficient basis for the proof of the +existence of the Deity, we can make the attempt by the only other +mode--that of grounding our argument upon a determinate experience +of the phenomena of the present world, their constitution and +disposition, and discover whether we can thus attain to a sound +conviction of the existence of a Supreme Being. This argument we shall +term the physico-theological argument. If it is shown to be +insufficient, speculative reason cannot present us with any +satisfactory proof of the existence of a being corresponding to our +transcendental idea. + +It is evident from the remarks that have been made in the +preceding sections, that an answer to this question will be far from +being difficult or unconvincing. For how can any experience be +adequate with an idea? The very essence of an idea consists in the +fact that no experience can ever be discovered congruent or adequate +with it. The transcendental idea of a necessary and all-sufficient +being is so immeasurably great, so high above all that is empirical, +which is always conditioned, that we hope in vain to find materials +in the sphere of experience sufficiently ample for our conception, +and in vain seek the unconditioned among things that are conditioned, +while examples, nay, even guidance is denied us by the laws of empirical +synthesis. + +If the Supreme Being forms a link in the chain of empirical +conditions, it must be a member of the empirical series, and, like +the lower members which it precedes, have its origin in some higher +member of the series. If, on the other hand, we disengage it from the +chain, and cogitate it as an intelligible being, apart from the series +of natural causes--how shall reason bridge the abyss that separates +the latter from the former? All laws respecting the regress from +effects to causes, all synthetical additions to our knowledge relate +solely to possible experience and the objects of the sensuous world, +and, apart from them, are without significance. + +The world around us opens before our view so magnificent a spectacle +of order, variety, beauty, and conformity to ends, that whether we +pursue our observations into the infinity of space in the one +direction, or into its illimitable divisions in the other, whether +we regard the world in its greatest or its least manifestations- +even after we have attained to the highest summit of knowledge which +our weak minds can reach, we find that language in the presence of +wonders so inconceivable has lost its force, and number its power to +reckon, nay, even thought fails to conceive adequately, and our +conception of the whole dissolves into an astonishment without power +of expression--all the more eloquent that it is dumb. Everywhere +around us we observe a chain of causes and effects, of means and ends, +of death and birth; and, as nothing has entered of itself into the +condition in which we find it, we are constantly referred to some +other thing, which itself suggests the same inquiry regarding its +cause, and thus the universe must sink into the abyss of +nothingness, unless we admit that, besides this infinite chain of +contingencies, there exists something that is primal and +self-subsistent--something which, as the cause of this phenomenal +world, secures its continuance and preservation. + +This highest cause--what magnitude shall we attribute to it? Of +the content of the world we are ignorant; still less can we estimate +its magnitude by comparison with the sphere of the possible. But +this supreme cause being a necessity of the human mind, what is +there to prevent us from attributing to it such a degree of perfection +as to place it above the sphere of all that is possible? This we can +easily do, although only by the aid of the faint outline of an +abstract conception, by representing this being to ourselves as +containing in itself, as an individual substance, all possible +perfection--a conception which satisfies that requirement of reason +which demands parsimony in principles, which is free from +self-contradiction, which even contributes to the extension of the +employment of reason in experience, by means of the guidance +afforded by this idea to order and system, and which in no respect +conflicts with any law of experience. + +This argument always deserves to be mentioned with respect. It is +the oldest, the clearest, and that most in conformity with the +common reason of humanity. It animates the study of nature, as it +itself derives its existence and draws ever new strength from that +source. It introduces aims and ends into a sphere in which our +observation could not of itself have discovered them, and extends +our knowledge of nature, by directing our attention to a unity, the +principle of which lies beyond nature. This knowledge of nature +again reacts upon this idea--its cause; and thus our belief in a +divine author of the universe rises to the power of an irresistible +conviction. + +For these reasons it would be utterly hopeless to attempt to rob +this argument of the authority it has always enjoyed. The mind, +unceasingly elevated by these considerations, which, although +empirical, are so remarkably powerful, and continually adding to their +force, will not suffer itself to be depressed by the doubts +suggested by subtle speculation; it tears itself out of this state +of uncertainty, the moment it casts a look upon the wondrous forms +of nature and the majesty of the universe, and rises from height to +height, from condition to condition, till it has elevated itself to +the supreme and unconditioned author of all. + +But although we have nothing to object to the reasonableness and +utility of this procedure, but have rather to commend and encourage +it, we cannot approve of the claims which this argument advances to +demonstrative certainty and to a reception upon its own merits, +apart from favour or support by other arguments. Nor can it injure +the cause of morality to endeavour to lower the tone of the arrogant +sophist, and to teach him that modesty and moderation which are the +properties of a belief that brings calm and content into the mind, +without prescribing to it an unworthy subjection. I maintain, then, +that the physico-theological argument is insufficient of itself to +prove the existence of a Supreme Being, that it must entrust this to +the ontological argument--to which it serves merely as an +introduction, and that, consequently, this argument contains the +only possible ground of proof (possessed by speculative reason) for +the existence of this being. + +The chief momenta in the physico-theological argument are as follow: +1. We observe in the world manifest signs of an arrangement full of +purpose, executed with great wisdom, and argument in whole of a +content indescribably various, and of an extent without limits. 2. +This arrangement of means and ends is entirely foreign to the things +existing in the world--it belongs to them merely as a contingent +attribute; in other words, the nature of different things could not +of itself, whatever means were employed, harmoniously tend towards +certain purposes, were they not chosen and directed for these purposes +by a rational and disposing principle, in accordance with certain +fundamental ideas. 3. There exists, therefore, a sublime and wise +cause (or several), which is not merely a blind, all-powerful +nature, producing the beings and events which fill the world in +unconscious fecundity, but a free and intelligent cause of the +world. 4. The unity of this cause may be inferred from the unity of +the reciprocal relation existing between the parts of the world, as +portions of an artistic edifice--an inference which all our +observation favours, and all principles of analogy support. + +In the above argument, it is inferred from the analogy of certain +products of nature with those of human art, when it compels Nature +to bend herself to its purposes, as in the case of a house, a ship, +or a watch, that the same kind of causality--namely, understanding +and will--resides in nature. It is also declared that the internal +possibility of this freely-acting nature (which is the source of all +art, and perhaps also of human reason) is derivable from another and +superhuman art--a conclusion which would perhaps be found incapable +of standing the test of subtle transcendental criticism. But to neither +of these opinions shall we at present object. We shall only remark +that it must be confessed that, if we are to discuss the subject of +cause at all, we cannot proceed more securely than with the guidance +of the analogy subsisting between nature and such products of +design--these being the only products whose causes and modes of +organization are completely known to us. Reason would be unable to +satisfy her own requirements, if she passed from a causality which +she does know, to obscure and indemonstrable principles of explanation +which she does not know. + +According to the physico-theological argument, the connection and +harmony existing in the world evidence the contingency of the form +merely, but not of the matter, that is, of the substance of the world. +To establish the truth of the latter opinion, it would be necessary +to prove that all things would be in themselves incapable of this harmony +and order, unless they were, even as regards their substance, the +product of a supreme wisdom. But this would require very different +grounds of proof from those presented by the analogy with human art. +This proof can at most, therefore, demonstrate the existence of an +architect of the world, whose efforts are limited by the +capabilities of the material with which he works, but not of a creator +of the world, to whom all things are subject. Thus this argument is +utterly insufficient for the task before us--a demonstration of the +existence of an all-sufficient being. If we wish to prove the +contingency of matter, we must have recourse to a transcendental +argument, which the physico-theological was constructed expressly to +avoid. + +We infer, from the order and design visible in the universe, as a +disposition of a thoroughly contingent character, the existence of +a cause proportionate thereto. The conception of this cause must contain +certain determinate qualities, and it must therefore be regarded as +the conception of a being which possesses all power, wisdom, and so +on, in one word, all perfection--the conception, that is, of an +all-sufficient being. For the predicates of very great, astonishing, +or immeasurable power and excellence, give us no determinate +conception of the thing, nor do they inform us what the thing may be +in itself. They merely indicate the relation existing between the +magnitude of the object and the observer, who compares it with himself +and with his own power of comprehension, and are mere expressions of +praise and reverence, by which the object is either magnified, or +the observing subject depreciated in relation to the object. Where +we have to do with the magnitude (of the perfection) of a thing, we +can discover no determinate conception, except that which +comprehends all possible perfection or completeness, and it is only +the total (omnitudo) of reality which is completely determined in +and through its conception alone. + +Now it cannot be expected that any one will be bold enough to +declare that he has a perfect insight into the relation which the +magnitude of the world he contemplates bears (in its extent as well +as in its content) to omnipotence, into that of the order and design +in the world to the highest wisdom, and that of the unity of the world +to the absolute unity of a Supreme Being. Physico-theology is therefore +incapable of presenting a determinate conception of a supreme cause +of the world, and is therefore insufficient as a principle of theology--a +theology which is itself to be the basis of religion. + +The attainment of absolute totality is completely impossible on +the path of empiricism. And yet this is the path pursued in the +physico-theological argument. What means shall we employ to bridge +the abyss? + +After elevating ourselves to admiration of the magnitude of the +power, wisdom, and other attributes of the author of the world, and +finding we can advance no further, we leave the argument on +empirical grounds, and proceed to infer the contingency of the world +from the order and conformity to aims that are observable in it. +From this contingency we infer, by the help of transcendental +conceptions alone, the existence of something absolutely necessary; +and, still advancing, proceed from the conception of the absolute +necessity of the first cause to the completely determined or +determining conception thereof--the conception of an all-embracing +reality. Thus the physico-theological, failing in its undertaking, +recurs in its embarrassment to the cosmological argument; and, as this +is merely the ontological argument in disguise, it executes its design +solely by the aid of pure reason, although it at first professed to +have no connection with this faculty and to base its entire +procedure upon experience alone. + +The physico-theologians have therefore no reason to regard with such +contempt the transcendental mode of argument, and to look down upon +it, with the conceit of clear-sighted observers of nature, as the +brain-cobweb of obscure speculatists. For, if they reflect upon and +examine their own arguments, they will find that, after following +for some time the path of nature and experience, and discovering +themselves no nearer their object, they suddenly leave this path and +pass into the region of pure possibility, where they hope to reach +upon the wings of ideas what had eluded all their empirical +investigations. Gaining, as they think, a firm footing after this +immense leap, they extend their determinate conception--into the +possession of which they have come, they know not how--over the +whole sphere of creation, and explain their ideal, which is entirely +a product of pure reason, by illustrations drawn from experience--though +in a degree miserably unworthy of the grandeur of the object, while +they refuse to acknowledge that they have arrived at this cognition +or hypothesis by a very different road from that of experience. + +Thus the physico-theological is based upon the cosmological, and +this upon the ontological proof of the existence of a Supreme Being; +and as besides these three there is no other path open to +speculative reason, the ontological proof, on the ground of pure +conceptions of reason, is the only possible one, if any proof of a +proposition so far transcending the empirical exercise of the +understanding is possible at all. + + + +SECTION VII. Critique of all Theology based upon Speculative + Principles of Reason. + +If by the term theology I understand the cognition of a primal +being, that cognition is based either upon reason alone (theologia +rationalis) or upon revelation (theologia revelata). The former +cogitates its object either by means of pure transcendental +conceptions, as an ens originarium, realissimum, ens entium, and is +termed transcendental theology; or, by means of a conception derived +from the nature of our own mind, as a supreme intelligence, and must +then be entitled natural theology. The person who believes in a +transcendental theology alone, is termed a deist; he who +acknowledges the possibility of a natural theology also, a theist. +The former admits that we can cognize by pure reason alone the existence +of a Supreme Being, but at the same time maintains that our conception +of this being is purely transcendental, and that all we can say of +it is that it possesses all reality, without being able to define it +more closely. The second asserts that reason is capable of +presenting us, from the analogy with nature, with a more definite +conception of this being, and that its operations, as the cause of +all things, are the results of intelligence and free will. The former +regards the Supreme Being as the cause of the world--whether by the +necessity of his nature, or as a free agent, is left undetermined; +the latter considers this being as the author of the world. + +Transcendental theology aims either at inferring the existence of +a Supreme Being from a general experience, without any closer +reference to the world to which this experience belongs, and in this +case it is called cosmotheology; or it endeavours to cognize the +existence of such a being, through mere conceptions, without the aid +of experience, and is then termed ontotheology. + +Natural theology infers the attributes and the existence of an +author of the world, from the constitution of, the order and unity +observable in, the world, in which two modes of causality must be +admitted to exist--those of nature and freedom. Thus it rises from +this world to a supreme intelligence, either as the principle of all +natural, or of all moral order and perfection. In the former case it +is termed physico-theology, in the latter, ethical or moral-theology.* + +[*Footnote: Not theological ethics; for this science contains ethical +laws, which presuppose the existence of a Supreme Governor of the world; +while moral-theology, on the contrary, is the expression of a +conviction of the existence of a Supreme Being, founded upon ethical +laws.] + +As we are wont to understand by the term God not merely an eternal +nature, the operations of which are insensate and blind, but a Supreme +Being, who is the free and intelligent author of all things, and as +it is this latter view alone that can be of interest to humanity, we +might, in strict rigour, deny to the deist any belief in God at all, +and regard him merely as a maintainer of the existence of a primal +being or thing--the supreme cause of all other things. But, as no +one ought to be blamed, merely because he does not feel himself +justified in maintaining a certain opinion, as if he altogether denied +its truth and asserted the opposite, it is more correct--as it is less +harsh--to say, the deist believes in a God, the theist in a living +God (summa intelligentia). We shall now proceed to investigate the +sources of all these attempts of reason to establish the existence +of a Supreme Being. + +It may be sufficient in this place to define theoretical knowledge +or cognition as knowledge of that which is, and practical knowledge +as knowledge of that which ought to be. In this view, the theoretical +employment of reason is that by which I cognize a priori (as +necessary) that something is, while the practical is that by which +I cognize a priori what ought to happen. Now, if it is an indubitably +certain, though at the same time an entirely conditioned truth, that +something is, or ought to happen, either a certain determinate +condition of this truth is absolutely necessary, or such a condition +may be arbitrarily presupposed. In the former case the condition is +postulated (per thesin), in the latter supposed (per hypothesin). +There are certain practical laws--those of morality--which are +absolutely necessary. Now, if these laws necessarily presuppose the +existence of some being, as the condition of the possibility of +their obligatory power, this being must be postulated, because the +conditioned, from which we reason to this determinate condition, is +itself cognized a priori as absolutely necessary. We shall at some +future time show that the moral laws not merely presuppose the +existence of a Supreme Being, but also, as themselves absolutely +necessary in a different relation, demand or postulate it--although +only from a practical point of view. The discussion of this argument +we postpone for the present. + +When the question relates merely to that which is, not to that which +ought to be, the conditioned which is presented in experience is +always cogitated as contingent. For this reason its condition cannot +be regarded as absolutely necessary, but merely as relatively +necessary, or rather as needful; the condition is in itself and a +priori a mere arbitrary presupposition in aid of the cognition, by +reason, of the conditioned. If, then, we are to possess a +theoretical cognition of the absolute necessity of a thing, we +cannot attain to this cognition otherwise than a priori by means of +conceptions; while it is impossible in this way to cognize the +existence of a cause which bears any relation to an existence given +in experience. + +Theoretical cognition is speculative when it relates to an object or +certain conceptions of an object which is not given and cannot be +discovered by means of experience. It is opposed to the cognition of +nature, which concerns only those objects or predicates which can be +presented in a possible experience. + +The principle that everything which happens (the empirically +contingent) must have a cause, is a principle of the cognition of +nature, but not of speculative cognition. For, if we change it into +an abstract principle, and deprive it of its reference to experience +and the empirical, we shall find that it cannot with justice be +regarded any longer as a synthetical proposition, and that it is +impossible to discover any mode of transition from that which exists +to something entirely different--termed cause. Nay, more, the +conception of a cause likewise that of the contingent--loses, in +this speculative mode of employing it, all significance, for its +objective reality and meaning are comprehensible from experience +alone. + +When from the existence of the universe and the things in it the +existence of a cause of the universe is inferred, reason is proceeding +not in the natural, but in the speculative method. For the principle +of the former enounces, not that things themselves or substances, +but only that which happens or their states--as empirically +contingent, have a cause: the assertion that the existence of +substance itself is contingent is not justified by experience, it is +the assertion of a reason employing its principles in a speculative +manner. If, again, I infer from the form of the universe, from the +way in which all things are connected and act and react upon each other, +the existence of a cause entirely distinct from the universe--this +would again be a judgement of purely speculative reason; because the +object in this case--the cause--can never be an object of possible +experience. In both these cases the principle of causality, which is +valid only in the field of experience--useless and even meaningless +beyond this region, would be diverted from its proper destination. + +Now I maintain that all attempts of reason to establish a theology +by the aid of speculation alone are fruitless, that the principles +of reason as applied to nature do not conduct us to any theological +truths, and, consequently, that a rational theology can have no +existence, unless it is founded upon the laws of morality. For all +synthetical principles of the understanding are valid only as immanent +in experience; while the cognition of a Supreme Being necessitates +their being employed transcendentally, and of this the understanding +is quite incapable. If the empirical law of causality is to conduct +us to a Supreme Being, this being must belong to the chain of empirical +objects--in which case it would be, like all phenomena, itself +conditioned. If the possibility of passing the limits of experience +be admitted, by means of the dynamical law of the relation of an effect +to its cause, what kind of conception shall we obtain by this +procedure? Certainly not the conception of a Supreme Being, because +experience never presents us with the greatest of all possible +effects, and it is only an effect of this character that could witness +to the existence of a corresponding cause. If, for the purpose of +fully satisfying the requirements of Reason, we recognize her right +to assert the existence of a perfect and absolutely necessary being, +this can be admitted only from favour, and cannot be regarded as the +result or irresistible demonstration. The physico-theological proof +may add weight to others--if other proofs there are--by connecting +speculation with experience; but in itself it rather prepares the mind +for theological cognition, and gives it a right and natural direction, +than establishes a sure foundation for theology. + +It is now perfectly evident that transcendental questions admit only +of transcendental answers--those presented a priori by pure +conceptions without the least empirical admixture. But the question +in the present case is evidently synthetical--it aims at the extension +of our cognition beyond the bounds of experience--it requires an +assurance respecting the existence of a being corresponding with the +idea in our minds, to which no experience can ever be adequate. Now +it has been abundantly proved that all a priori synthetical cognition +is possible only as the expression of the formal conditions of a +possible experience; and that the validity of all principles depends +upon their immanence in the field of experience, that is, their +relation to objects of empirical cognition or phenomena. Thus all +transcendental procedure in reference to speculative theology is +without result. + +If any one prefers doubting the conclusiveness of the proofs of +our analytic to losing the persuasion of the validity of these old +and time honoured arguments, he at least cannot decline answering the +question--how he can pass the limits of all possible experience by +the help of mere ideas. If he talks of new arguments, or of improvements +upon old arguments, I request him to spare me. There is certainly no +great choice in this sphere of discussion, as all speculative +arguments must at last look for support to the ontological, and I +have, therefore, very little to fear from the argumentative +fecundity of the dogmatical defenders of a non-sensuous reason. +Without looking upon myself as a remarkably combative person, I +shall not decline the challenge to detect the fallacy and destroy +the pretensions of every attempt of speculative theology. And yet +the hope of better fortune never deserts those who are accustomed to +the dogmatical mode of procedure. I shall, therefore, restrict +myself to the simple and equitable demand that such reasoners will +demonstrate, from the nature of the human mind as well as from that +of the other sources of knowledge, how we are to proceed to extend +our cognition completely a priori, and to carry it to that point where +experience abandons us, and no means exist of guaranteeing the +objective reality of our conceptions. In whatever way the +understanding may have attained to a conception, the existence of +the object of the conception cannot be discovered in it by analysis, +because the cognition of the existence of the object depends upon +the object's being posited and given in itself apart from the +conception. But it is utterly impossible to go beyond our +conception, without the aid of experience--which presents to the +mind nothing but phenomena, or to attain by the help of mere +conceptions to a conviction of the existence of new kinds of objects +or supernatural beings. + +But although pure speculative reason is far from sufficient to +demonstrate the existence of a Supreme Being, it is of the highest +utility in correcting our conception of this being--on the supposition +that we can attain to the cognition of it by some other means--in +making it consistent with itself and with all other conceptions of +intelligible objects, clearing it from all that is incompatible with +the conception of an ens summun, and eliminating from it all +limitations or admixtures of empirical elements. + +Transcendental theology is still therefore, notwithstanding its +objective insufficiency, of importance in a negative respect; it is +useful as a test of the procedure of reason when engaged with pure +ideas, no other than a transcendental standard being in this case +admissible. For if, from a practical point of view, the hypothesis +of a Supreme and All-sufficient Being is to maintain its validity +without opposition, it must be of the highest importance to define +this conception in a correct and rigorous manner--as the +transcendental conception of a necessary being, to eliminate all +phenomenal elements (anthropomorphism in its most extended +signification), and at the same time to overflow all contradictory +assertions--be they atheistic, deistic, or anthropomorphic. This is +of course very easy; as the same arguments which demonstrated the +inability of human reason to affirm the existence of a Supreme Being +must be alike sufficient to prove the invalidity of its denial. For +it is impossible to gain from the pure speculation of reason +demonstration that there exists no Supreme Being, as the ground of +all that exists, or that this being possesses none of those properties +which we regard as analogical with the dynamical qualities of a +thinking being, or that, as the anthropomorphists would have us +believe, it is subject to all the limitations which sensibility +imposes upon those intelligences which exist in the world of +experience. + +A Supreme Being is, therefore, for the speculative reason, a mere +ideal, though a faultless one--a conception which perfects and +crowns the system of human cognition, but the objective reality of +which can neither be proved nor disproved by pure reason. If this +defect is ever supplied by a moral theology, the problematic +transcendental theology which has preceded, will have been at least +serviceable as demonstrating the mental necessity existing for the +conception, by the complete determination of it which it has +furnished, and the ceaseless testing of the conclusions of a reason +often deceived by sense, and not always in harmony with its own ideas. +The attributes of necessity, infinitude, unity, existence apart from +the world (and not as a world soul), eternity (free from conditions +of time), omnipresence (free from conditions of space), omnipotence, +and others, are pure transcendental predicates; and thus the +accurate conception of a Supreme Being, which every theology requires, +is furnished by transcendental theology alone. + + + +APPENDIX. + +Of the Regulative Employment of the Ideas of Pure Reason. + +The result of all the dialectical attempts of pure reason not only +confirms the truth of what we have already proved in our +Transcendental Analytic, namely, that all inferences which would +lead us beyond the limits of experience are fallacious and groundless, +but it at the same time teaches us this important lesson, that human +reason has a natural inclination to overstep these limits, and that +transcendental ideas are as much the natural property of the reason +as categories are of the understanding. There exists this difference, +however, that while the categories never mislead us, outward objects +being always in perfect harmony therewith, ideas are the parents of +irresistible illusions, the severest and most subtle criticism being +required to save us from the fallacies which they induce. + +Whatever is grounded in the nature of our powers will be found to be +in harmony with the final purpose and proper employment of these +powers, when once we have discovered their true direction and aim. +We are entitled to suppose, therefore, that there exists a mode of +employing transcendental ideas which is proper and immanent; although, +when we mistake their meaning, and regard them as conceptions of +actual things, their mode of application is transcendent and delusive. +For it is not the idea itself, but only the employment of the idea +in relation to possible experience, that is transcendent or +immanent. An idea is employed transcendently, when it is applied to +an object falsely believed to be adequate with and to correspond to +it; imminently, when it is applied solely to the employment of the +understanding in the sphere of experience. Thus all errors of +subreptio--of misapplication, are to be ascribed to defects of +judgement, and not to understanding or reason. + +Reason never has an immediate relation to an object; it relates +immediately to the understanding alone. It is only through the +understanding that it can be employed in the field of experience. It +does not form conceptions of objects, it merely arranges them and +gives to them that unity which they are capable of possessing when +the sphere of their application has been extended as widely as possible. +Reason avails itself of the conception of the understanding for the +sole purpose of producing totality in the different series. This +totality the understanding does not concern itself with; its only +occupation is the connection of experiences, by which series of +conditions in accordance with conceptions are established. The +object of reason is, therefore, the understanding and its proper +destination. As the latter brings unity into the diversity of +objects by means of its conceptions, so the former brings unity into +the diversity of conceptions by means of ideas; as it sets the final +aim of a collective unity to the operations of the understanding, +which without this occupies itself with a distributive unity alone. + +I accordingly maintain that transcendental ideas can never be +employed as constitutive ideas, that they cannot be conceptions of +objects, and that, when thus considered, they assume a fallacious +and dialectical character. But, on the other hand, they are capable +of an admirable and indispensably necessary application to objects--as +regulative ideas, directing the understanding to a certain aim, the +guiding lines towards which all its laws follow, and in which they +all meet in one point. This point--though a mere idea (focus imaginarius), +that is, not a point from which the conceptions of the understanding +do really proceed, for it lies beyond the sphere of possible +experience--serves, notwithstanding, to give to these conceptions +the greatest possible unity combined with the greatest possible +extension. Hence arises the natural illusion which induces us to +believe that these lines proceed from an object which lies out of +the sphere of empirical cognition, just as objects reflected in a +mirror appear to be behind it. But this illusion--which we may +hinder from imposing upon us--is necessary and unavoidable, if we +desire to see, not only those objects which lie before us, but those +which are at a great distance behind us; that is to say, when, in +the present case, we direct the aims of the understanding, beyond +every given experience, towards an extension as great as can +possibly be attained. + +If we review our cognitions in their entire extent, we shall find +that the peculiar business of reason is to arrange them into a system, +that is to say, to give them connection according to a principle. This +unity presupposes an idea--the idea of the form of a whole (of +cognition), preceding the determinate cognition of the parts, and +containing the conditions which determine a priori to every part its +place and relation to the other parts of the whole system. This +idea, accordingly, demands complete unity in the cognition of the +understanding--not the unity of a contingent aggregate, but that of +a system connected according to necessary laws. It cannot be +affirmed with propriety that this idea is a conception of an object; +it is merely a conception of the complete unity of the conceptions +of objects, in so far as this unity is available to the +understanding as a rule. Such conceptions of reason are not derived +from nature; on the contrary, we employ them for the interrogation +and investigation of nature, and regard our cognition as defective +so long as it is not adequate to them. We admit that such a thing as +pure earth, pure water, or pure air, is not to be discovered. And yet +we require these conceptions (which have their origin in the reason, +so far as regards their absolute purity and completeness) for the purpose +of determining the share which each of these natural causes has in +every phenomenon. Thus the different kinds of matter are all referred +to earths, as mere weight; to salts and inflammable bodies, as pure +force; and finally, to water and air, as the vehicula of the former, +or the machines employed by them in their operations--for the +purpose of explaining the chemical action and reaction of bodies in +accordance with the idea of a mechanism. For, although not actually +so expressed, the influence of such ideas of reason is very observable +in the procedure of natural philosophers. + +If reason is the faculty of deducing the particular from the +general, and if the general be certain in se and given, it is only +necessary that the judgement should subsume the particular under the +general, the particular being thus necessarily determined. I shall +term this the demonstrative or apodeictic employment of reason. If, +however, the general is admitted as problematical only, and is a +mere idea, the particular case is certain, but the universality of +the rule which applies to this particular case remains a problem. +Several particular cases, the certainty of which is beyond doubt, +are then taken and examined, for the purpose of discovering whether +the rule is applicable to them; and if it appears that all the +particular cases which can be collected follow from the rule, its +universality is inferred, and at the same time, all the causes which +have not, or cannot be presented to our observation, are concluded +to be of the same character with those which we have observed. This +I shall term the hypothetical employment of the reason. + +The hypothetical exercise of reason by the aid of ideas employed +as problematical conceptions is properly not constitutive. That is +to say, if we consider the subject strictly, the truth of the rule, +which has been employed as an hypothesis, does not follow from the +use that is made of it by reason. For how can we know all the possible +cases that may arise? some of which may, however, prove exceptions +to the universality of the rule. This employment of reason is merely +regulative, and its sole aim is the introduction of unity into the +aggregate of our particular cognitions, and thereby the +approximating of the rule to universality. + +The object of the hypothetical employment of reason is therefore the +systematic unity of cognitions; and this unity is the criterion of +the truth of a rule. On the other hand, this systematic unity--as a +mere idea--is in fact merely a unity projected, not to be regarded +as given, but only in the light of a problem--a problem which serves, +however, as a principle for the various and particular exercise of +the understanding in experience, directs it with regard to those cases +which are not presented to our observation, and introduces harmony +and consistency into all its operations. + +All that we can be certain of from the above considerations is +that this systematic unity is a logical principle, whose aim is to +assist the understanding, where it cannot of itself attain to rules, +by means of ideas, to bring all these various rules under one +principle, and thus to ensure the most complete consistency and +connection that can be attained. But the assertion that objects and +the understanding by which they are cognized are so constituted as +to be determined to systematic unity, that this may be postulated a +priori, without any reference to the interest of reason, and that we +are justified in declaring all possible cognitions--empirical and +others--to possess systematic unity, and to be subject to general +principles from which, notwithstanding their various character, they +are all derivable such an assertion can be founded only upon a +transcendental principle of reason, which would render this systematic +unity not subjectively and logically--in its character of a method, +but objectively necessary. + +We shall illustrate this by an example. The conceptions of the +understanding make us acquainted, among many other kinds of unity, +with that of the causality of a substance, which is termed power. +The different phenomenal manifestations of the same substance appear +at first view to be so very dissimilar that we are inclined to +assume the existence of just as many different powers as there are +different effects--as, in the case of the human mind, we have feeling, +consciousness, imagination, memory, wit, analysis, pleasure, desire +and so on. Now we are required by a logical maxim to reduce these +differences to as small a number as possible, by comparing them and +discovering the hidden identity which exists. We must inquire, for +example, whether or not imagination (connected with consciousness), +memory, wit, and analysis are not merely different forms of +understanding and reason. The idea of a fundamental power, the +existence of which no effort of logic can assure us of, is the problem +to be solved, for the systematic representation of the existing +variety of powers. The logical principle of reason requires us to +produce as great a unity as is possible in the system of our +cognitions; and the more the phenomena of this and the other power +are found to be identical, the more probable does it become, that they +are nothing but different manifestations of one and the same power, +which may be called, relatively speaking, a fundamental power. And +so with other cases. + +These relatively fundamental powers must again be compared with each +other, to discover, if possible, the one radical and absolutely +fundamental power of which they are but the manifestations. But this +unity is purely hypothetical. It is not maintained, that this unity +does really exist, but that we must, in the interest of reason, that +is, for the establishment of principles for the various rules +presented by experience, try to discover and introduce it, so far as +is practicable, into the sphere of our cognitions. + +But the transcendental employment of the understanding would lead us +to believe that this idea of a fundamental power is not problematical, +but that it possesses objective reality, and thus the systematic unity +of the various powers or forces in a substance is demanded by the +understanding and erected into an apodeictic or necessary principle. +For, without having attempted to discover the unity of the various +powers existing in nature, nay, even after all our attempts have +failed, we notwithstanding presuppose that it does exist, and may +be, sooner or later, discovered. And this reason does, not only, as +in the case above adduced, with regard to the unity of substance, but +where many substances, although all to a certain extent homogeneous, +are discoverable, as in the case of matter in general. Here also +does reason presuppose the existence of the systematic unity of +various powers--inasmuch as particular laws of nature are +subordinate to general laws; and parsimony in principles is not merely +an economical principle of reason, but an essential law of nature. + +We cannot understand, in fact, how a logical principle of unity +can of right exist, unless we presuppose a transcendental principle, +by which such a systematic unit--as a property of objects +themselves--is regarded as necessary a priori. For with what right +can reason, in its logical exercise, require us to regard the variety +of forces which nature displays, as in effect a disguised unity, and +to deduce them from one fundamental force or power, when she is free +to admit that it is just as possible that all forces should be +different in kind, and that a systematic unity is not conformable to +the design of nature? In this view of the case, reason would be +proceeding in direct opposition to her own destination, by setting +as an aim an idea which entirely conflicts with the procedure and +arrangement of nature. Neither can we assert that reason has +previously inferred this unity from the contingent nature of +phenomena. For the law of reason which requires us to seek for this +unity is a necessary law, inasmuch as without it we should not possess +a faculty of reason, nor without reason a consistent and +self-accordant mode of employing the understanding, nor, in the +absence of this, any proper and sufficient criterion of empirical +truth. In relation to this criterion, therefore, we must suppose the +idea of the systematic unity of nature to possess objective validity +and necessity. + +We find this transcendental presupposition lurking in different +forms in the principles of philosophers, although they have neither +recognized it nor confessed to themselves its presence. That the +diversities of individual things do not exclude identity of species, +that the various species must be considered as merely different +determinations of a few genera, and these again as divisions of +still higher races, and so on--that, accordingly, a certain systematic +unity of all possible empirical conceptions, in so far as they can +be deduced from higher and more general conceptions, must be sought +for, is a scholastic maxim or logical principle, without which +reason could not be employed by us. For we can infer the particular +from the general, only in so far as general properties of things +constitute the foundation upon which the particular rest. + +That the same unity exists in nature is presupposed by +philosophers in the well-known scholastic maxim, which forbids us +unnecessarily to augment the number of entities or principles (entia +praeter necessitatem non esse multiplicanda). This maxim asserts +that nature herself assists in the establishment of this unity of +reason, and that the seemingly infinite diversity of phenomena +should not deter us from the expectation of discovering beneath this +diversity a unity of fundamental properties, of which the aforesaid +variety is but a more or less determined form. This unity, although +a mere idea, thinkers have found it necessary rather to moderate the +desire than to encourage it. It was considered a great step when +chemists were able to reduce all salts to two main genera--acids and +alkalis; and they regard this difference as itself a mere variety, +or different manifestation of one and the same fundamental material. +The different kinds of earths (stones and even metals) chemists have +endeavoured to reduce to three, and afterwards to two; but still, +not content with this advance, they cannot but think that behind these +diversities there lurks but one genus--nay, that even salts and earths +have a common principle. It might be conjectured that this is merely +an economical plan of reason, for the purpose of sparing itself +trouble, and an attempt of a purely hypothetical character, which, +when successful, gives an appearance of probability to the principle +of explanation employed by the reason. But a selfish purpose of this +kind is easily to be distinguished from the idea, according to which +every one presupposes that this unity is in accordance with the laws +of nature, and that reason does not in this case request, but +requires, although we are quite unable to determine the proper +limits of this unity. + +If the diversity existing in phenomena--a diversity not of form (for +in this they may be similar) but of content--were so great that the +subtlest human reason could never by comparison discover in them the +least similarity (which is not impossible), in this case the logical +law of genera would be without foundation, the conception of a +genus, nay, all general conceptions would be impossible, and the +faculty of the understanding, the exercise of which is restricted to +the world of conceptions, could not exist. The logical principle of +genera, accordingly, if it is to be applied to nature (by which I mean +objects presented to our senses), presupposes a transcendental +principle. In accordance with this principle, homogeneity is +necessarily presupposed in the variety of phenomena (although we are +unable to determine a priori the degree of this homogeneity), +because without it no empirical conceptions, and consequently no +experience, would be possible. + +The logical principle of genera, which demands identity in +phenomena, is balanced by another principle--that of species, which +requires variety and diversity in things, notwithstanding their +accordance in the same genus, and directs the understanding to +attend to the one no less than to the other. This principle (of the +faculty of distinction) acts as a check upon the reason and reason +exhibits in this respect a double and conflicting interest--on the +one hand, the interest in the extent (the interest of generality) in +relation to genera; on the other, that of the content (the interest +of individuality) in relation to the variety of species. In the former +case, the understanding cogitates more under its conceptions, in the +latter it cogitates more in them. This distinction manifests itself +likewise in the habits of thought peculiar to natural philosophers, +some of whom--the remarkably speculative heads--may be said to be +hostile to heterogeneity in phenomena, and have their eyes always +fixed on the unity of genera, while others--with a strong empirical +tendency--aim unceasingly at the analysis of phenomena, and almost +destroy in us the hope of ever being able to estimate the character +of these according to general principles. + +The latter mode of thought is evidently based upon a logical +principle, the aim of which is the systematic completeness of all +cognitions. This principle authorizes me, beginning at the genus, to +descend to the various and diverse contained under it; and in this +way extension, as in the former case unity, is assured to the system. +For if we merely examine the sphere of the conception which +indicates a genus, we cannot discover how far it is possible to +proceed in the division of that sphere; just as it is impossible, from +the consideration of the space occupied by matter, to determine how +far we can proceed in the division of it. Hence every genus must +contain different species, and these again different subspecies; and +as each of the latter must itself contain a sphere (must be of a +certain extent, as a conceptus communis), reason demands that no +species or sub-species is to be considered as the lowest possible. +For a species or sub-species, being always a conception, which contains +only what is common to a number of different things, does not +completely determine any individual thing, or relate immediately to +it, and must consequently contain other conceptions, that is, other +sub-species under it. This law of specification may be thus expressed: +entium varietates non temere sunt minuendae. + +But it is easy to see that this logical law would likewise be +without sense or application, were it not based upon a +transcendental law of specification, which certainly does not +require that the differences existing phenomena should be infinite +in number, for the logical principle, which merely maintains the +indeterminateness of the logical sphere of a conception, in relation +to its possible division, does not authorize this statement; while +it does impose upon the understanding the duty of searching for +subspecies to every species, and minor differences in every +difference. For, were there no lower conceptions, neither could +there be any higher. Now the understanding cognizes only by means of +conceptions; consequently, how far soever it may proceed in +division, never by mere intuition, but always by lower and lower +conceptions. The cognition of phenomena in their complete +determination (which is possible only by means of the understanding) +requires an unceasingly continued specification of conceptions, and +a progression to ever smaller differences, of which abstraction bad +been made in the conception of the species, and still more in that +of the genus. + +This law of specification cannot be deduced from experience; it +can never present us with a principle of so universal an +application. Empirical specification very soon stops in its +distinction of diversities, and requires the guidance of the +transcendental law, as a principle of the reason--a law which +imposes on us the necessity of never ceasing in our search for +differences, even although these may not present themselves to the +senses. That absorbent earths are of different kinds could only be +discovered by obeying the anticipatory law of reason, which imposes +upon the understanding the task of discovering the differences +existing between these earths, and supposes that nature is richer in +substances than our senses would indicate. The faculty of the +understanding belongs to us just as much under the presupposition of +differences in the objects of nature, as under the condition that +these objects are homogeneous, because we could not possess +conceptions, nor make any use of our understanding, were not the +phenomena included under these conceptions in some respects +dissimilar, as well as similar, in their character. + +Reason thus prepares the sphere of the understanding for the +operations of this faculty: 1. By the principle of the homogeneity +of the diverse in higher genera; 2. By the principle of the variety +of the homogeneous in lower species; and, to complete the systematic +unity, it adds, 3. A law of the affinity of all conceptions which +prescribes a continuous transition from one species to every other +by the gradual increase of diversity. We may term these the principles +of the homogeneity, the specification, and the continuity of forms. +The latter results from the union of the two former, inasmuch as we +regard the systematic connection as complete in thought, in the ascent +to higher genera, as well as in the descent to lower species. For +all diversities must be related to each other, as they all spring from +one highest genus, descending through the different gradations of a +more and more extended determination. + +We may illustrate the systematic unity produced by the three logical +principles in the following manner. Every conception may be regarded +as a point, which, as the standpoint of a spectator, has a certain +horizon, which may be said to enclose a number of things that may be +viewed, so to speak, from that centre. Within this horizon there +must be an infinite number of other points, each of which has its +own horizon, smaller and more circumscribed; in other words, every +species contains sub-species, according to the principle of +specification, and the logical horizon consists of smaller horizons +(subspecies), but not of points (individuals), which possess no +extent. But different horizons or genera, which include under them +so many conceptions, may have one common horizon, from which, as +from a mid-point, they may be surveyed; and we may proceed thus, +till we arrive at the highest genus, or universal and true horizon, +which is determined by the highest conception, and which contains +under itself all differences and varieties, as genera, species, and +subspecies. + +To this highest standpoint I am conducted by the law of homogeneity, +as to all lower and more variously-determined conceptions by the law +of specification. Now as in this way there exists no void in the whole +extent of all possible conceptions, and as out of the sphere of +these the mind can discover nothing, there arises from the +presupposition of the universal horizon above mentioned, and its +complete division, the principle: Non datur vacuum formarum. This +principle asserts that there are not different primitive and highest +genera, which stand isolated, so to speak, from each other, but all +the various genera are mere divisions and limitations of one highest +and universal genus; and hence follows immediately the principle: +Datur continuum formarum. This principle indicates that all +differences of species limit each other, and do not admit of +transition from one to another by a saltus, but only through smaller +degrees of the difference between the one species and the other. In +one word, there are no species or sub-species which (in the view of +reason) are the nearest possible to each other; intermediate species +or sub-species being always possible, the difference of which from +each of the former is always smaller than the difference existing +between these. + +The first law, therefore, directs us to avoid the notion that +there exist different primal genera, and enounces the fact of +perfect homogeneity; the second imposes a check upon this tendency +to unity and prescribes the distinction of sub-species, before +proceeding to apply our general conceptions to individuals. The +third unites both the former, by enouncing the fact of homogeneity +as existing even in the most various diversity, by means of the +gradual transition from one species to another. Thus it indicates a +relationship between the different branches or species, in so far as +they all spring from the same stem. + +But this logical law of the continuum specierum (formarum logicarum) +presupposes a transcendental principle (lex continui in natura), +without which the understanding might be led into error, by +following the guidance of the former, and thus perhaps pursuing a path +contrary to that prescribed by nature. This law must, consequently, +be based upon pure transcendental, and not upon empirical, +considerations. For, in the latter case, it would come later than +the system; whereas it is really itself the parent of all that is +systematic in our cognition of nature. These principles are not mere +hypotheses employed for the purpose of experimenting upon nature; +although when any such connection is discovered, it forms a solid +ground for regarding the hypothetical unity as valid in the sphere +of nature--and thus they are in this respect not without their use. +But we go farther, and maintain that it is manifest that these +principles of parsimony in fundamental causes, variety in effects, +and affinity in phenomena, are in accordance both with reason and +nature, and that they are not mere methods or plans devised for the +purpose of assisting us in our observation of the external world. + +But it is plain that this continuity of forms is a mere idea, to +which no adequate object can be discovered in experience. And this +for two reasons. First, because the species in nature are really +divided, and hence form quanta discreta; and, if the gradual +progression through their affinity were continuous, the intermediate +members lying between two given species must be infinite in number, +which is impossible. Secondly, because we cannot make any +determinate empirical use of this law, inasmuch as it does not present +us with any criterion of affinity which could aid us in determining +how far we ought to pursue the graduation of differences: it merely +contains a general indication that it is our duty to seek for and, +if possible, to discover them. + +When we arrange these principles of systematic unity in the order +conformable to their employment in experience, they will stand thus: +Variety, Affinity, Unity, each of them, as ideas, being taken in the +highest degree of their completeness. Reason presupposes the existence +of cognitions of the understanding, which have a direct relation to +experience, and aims at the ideal unity of these cognitions--a unity +which far transcends all experience or empirical notions. The affinity +of the diverse, notwithstanding the differences existing between its +parts, has a relation to things, but a still closer one to the mere +properties and powers of things. For example, imperfect experience +may represent the orbits of the planets as circular. But we discover +variations from this course, and we proceed to suppose that the +planets revolve in a path which, if not a circle, is of a character +very similar to it. That is to say, the movements of those planets +which do not form a circle will approximate more or less to the +properties of a circle, and probably form an ellipse. The paths of +comets exhibit still greater variations, for, so far as our +observation extends, they do not return upon their own course in a +circle or ellipse. But we proceed to the conjecture that comets +describe a parabola, a figure which is closely allied to the +ellipse. In fact, a parabola is merely an ellipse, with its longer +axis produced to an indefinite extent. Thus these principles conduct +us to a unity in the genera of the forms of these orbits, and, +proceeding farther, to a unity as regards the cause of the motions +of the heavenly bodies--that is, gravitation. But we go on extending +our conquests over nature, and endeavour to explain all seeming +deviations from these rules, and even make additions to our system +which no experience can ever substantiate--for example, the theory, +in affinity with that of ellipses, of hyperbolic paths of comets, +pursuing which, these bodies leave our solar system and, passing +from sun to sun, unite the most distant parts of the infinite +universe, which is held together by the same moving power. + +The most remarkable circumstance connected with these principles +is that they seem to be transcendental, and, although only +containing ideas for the guidance of the empirical exercise of reason, +and although this empirical employment stands to these ideas in an +asymptotic relation alone (to use a mathematical term), that is, +continually approximate, without ever being able to attain to them, +they possess, notwithstanding, as a priori synthetical propositions, +objective though undetermined validity, and are available as rules +for possible experience. In the elaboration of our experience, they +may also be employed with great advantage, as heuristic [Footnote: +From the Greek, eurhioko.] principles. A transcendental deduction of +them cannot be made; such a deduction being always impossible in the +case of ideas, as has been already shown. + +We distinguished, in the Transcendental Analytic, the dynamical +principles of the understanding, which are regulative principles of +intuition, from the mathematical, which are constitutive principles +of intuition. These dynamical laws are, however, constitutive in relation +to experience, inasmuch as they render the conceptions without which +experience could not exist possible a priori. But the principles of +pure reason cannot be constitutive even in regard to empirical +conceptions, because no sensuous schema corresponding to them can be +discovered, and they cannot therefore have an object in concreto. Now, +if I grant that they cannot be employed in the sphere of experience, +as constitutive principles, how shall I secure for them employment +and objective validity as regulative principles, and in what way can +they be so employed? + +The understanding is the object of reason, as sensibility is the +object of the understanding. The production of systematic unity in +all the empirical operations of the understanding is the proper occupation +of reason; just as it is the business of the understanding to +connect the various content of phenomena by means of conceptions, +and subject them to empirical laws. But the operations of the +understanding are, without the schemata of sensibility, +undetermined; and, in the same manner, the unity of reason is +perfectly undetermined as regards the conditions under which, and +the extent to which, the understanding ought to carry the systematic +connection of its conceptions. But, although it is impossible to +discover in intuition a schema for the complete systematic unity of +all the conceptions of the understanding, there must be some +analogon of this schema. This analogon is the idea of the maximum of +the division and the connection of our cognition in one principle. +For we may have a determinate notion of a maximum and an absolutely +perfect, all the restrictive conditions which are connected with an +indeterminate and various content having been abstracted. Thus the +idea of reason is analogous with a sensuous schema, with this +difference, that the application of the categories to the schema of +reason does not present a cognition of any object (as is the case with +the application of the categories to sensuous schemata), but merely +provides us with a rule or principle for the systematic unity of the +exercise of the understanding. Now, as every principle which imposes +upon the exercise of the understanding a priori compliance with the +rule of systematic unity also relates, although only in an indirect +manner, to an object of experience, the principles of pure reason will +also possess objective reality and validity in relation to experience. +But they will not aim at determining our knowledge in regard to any +empirical object; they will merely indicate the procedure, following +which the empirical and determinate exercise of the understanding +may be in complete harmony and connection with itself--a result +which is produced by its being brought into harmony with the principle +of systematic unity, so far as that is possible, and deduced from it. + +I term all subjective principles, which are not derived from +observation of the constitution of an object, but from the interest +which Reason has in producing a certain completeness in her +cognition of that object, maxims of reason. Thus there are maxims of +speculative reason, which are based solely upon its speculative +interest, although they appear to be objective principles. + +When principles which are really regulative are regarded as +constitutive, and employed as objective principles, contradictions +must arise; but if they are considered as mere maxims, there is no +room for contradictions of any kind, as they then merely indicate +the different interests of reason, which occasion differences in the +mode of thought. In effect, Reason has only one single interest, and +the seeming contradiction existing between her maxims merely indicates +a difference in, and a reciprocal limitation of, the methods by +which this interest is satisfied. + +This reasoner has at heart the interest of diversity--in +accordance with the principle of specification; another, the +interest of unity--in accordance with the principle of aggregation. +Each believes that his judgement rests upon a thorough insight into +the subject he is examining, and yet it has been influenced solely +by a greater or less degree of adherence to some one of the two +principles, neither of which are objective, but originate solely +from the interest of reason, and on this account to be termed maxims +rather than principles. When I observe intelligent men disputing about +the distinctive characteristics of men, animals, or plants, and even +of minerals, those on the one side assuming the existence of certain +national characteristics, certain well-defined and hereditary +distinctions of family, race, and so on, while the other side maintain +that nature has endowed all races of men with the same faculties and +dispositions, and that all differences are but the result of +external and accidental circumstances--I have only to consider for +a moment the real nature of the subject of discussion, to arrive at +the conclusion that it is a subject far too deep for us to judge of, +and that there is little probability of either party being able to +speak from a perfect insight into and understanding of the nature of +the subject itself. Both have, in reality, been struggling for the +twofold interest of reason; the one maintaining the one interest, +the other the other. But this difference between the maxims of +diversity and unity may easily be reconciled and adjusted; although, +so long as they are regarded as objective principles, they must +occasion not only contradictions and polemic, but place hinderances +in the way of the advancement of truth, until some means is discovered +of reconciling these conflicting interests, and bringing reason into +union and harmony with itself. + +The same is the case with the so-called law discovered by Leibnitz, and +supported with remarkable ability by Bonnet--the law of the continuous +gradation of created beings, which is nothing more than an inference +from the principle of affinity; for observation and study of the order +of nature could never present it to the mind as an objective truth. The +steps of this ladder, as they appear in experience, are too far apart +from each other, and the so-called petty differences between different +kinds of animals are in nature commonly so wide separations that no +confidence can be placed in such views (particularly when we reflect on +the great variety of things, and the ease with which we can discover +resemblances), and no faith in the laws which are said to express the +aims and purposes of nature. On the other hand, the method of +investigating the order of nature in the light of this principle, and +the maxim which requires us to regard this order--it being still +undetermined how far it extends--as really existing in nature, is +beyond doubt a legitimate and excellent principle of reason--a +principle which extends farther than any experience or observation of +ours and which, without giving us any positive knowledge of anything in +the region of experience, guides us to the goal of systematic unity. + + + +Of the Ultimate End of the Natural Dialectic of Human Reason. + +The ideas of pure reason cannot be, of themselves and in their own +nature, dialectical; it is from their misemployment alone that +fallacies and illusions arise. For they originate in the nature of +reason itself, and it is impossible that this supreme tribunal for +all the rights and claims of speculation should be itself undeserving +of confidence and promotive of error. It is to be expected, therefore, +that these ideas have a genuine and legitimate aim. It is true, the +mob of sophists raise against reason the cry of inconsistency and +contradiction, and affect to despise the government of that faculty, +because they cannot understand its constitution, while it is to its +beneficial influences alone that they owe the position and the +intelligence which enable them to criticize and to blame its +procedure. + +We cannot employ an a priori conception with certainty, until we +have made a transcendental deduction therefore. The ideas of pure +reason do not admit of the same kind of deduction as the categories. +But if they are to possess the least objective validity, and to +represent anything but mere creations of thought (entia rationis +ratiocinantis), a deduction of them must be possible. This deduction +will complete the critical task imposed upon pure reason; and it is +to this part Of our labours that we now proceed. + +There is a great difference between a thing's being presented to the +mind as an object in an absolute sense, or merely as an ideal +object. In the former case I employ my conceptions to determine the +object; in the latter case nothing is present to the mind but a mere +schema, which does not relate directly to an object, not even in a +hypothetical sense, but which is useful only for the purpose of +representing other objects to the mind, in a mediate and indirect +manner, by means of their relation to the idea in the intellect. +Thus I say the conception of a supreme intelligence is a mere idea; +that is to say, its objective reality does not consist in the fact +that it has an immediate relation to an object (for in this sense we +have no means of establishing its objective validity), it is merely +a schema constructed according to the necessary conditions of the +unity of reason--the schema of a thing in general, which is useful +towards the production of the highest degree of systematic unity in +the empirical exercise of reason, in which we deduce this or that +object of experience from the imaginary object of this idea, as the +ground or cause of the said object of experience. In this way, the +idea is properly a heuristic, and not an ostensive, conception; it +does not give us any information respecting the constitution of an +object, it merely indicates how, under the guidance of the idea, we +ought to investigate the constitution and the relations of objects +in the world of experience. Now, if it can be shown that the three +kinds of transcendental ideas (psychological, cosmological, and +theological), although not relating directly to any object nor +determining it, do nevertheless, on the supposition of the existence +of an ideal object, produce systematic unity in the laws of the +empirical employment of the reason, and extend our empirical +cognition, without ever being inconsistent or in opposition with it- +it must be a necessary maxim of reason to regulate its procedure +according to these ideas. And this forms the transcendental +deduction of all speculative ideas, not as constitutive principles +of the extension of our cognition beyond the limits of our experience, +but as regulative principles of the systematic unity of empirical +cognition, which is by the aid of these ideas arranged and emended +within its own proper limits, to an extent unattainable by the +operation of the principles of the understanding alone. + +I shall make this plainer. Guided by the principles involved in +these ideas, we must, in the first place, so connect all the +phenomena, actions, and feelings of the mind, as if it were a simple +substance, which, endowed with personal identity, possesses a +permanent existence (in this life at least), while its states, among +which those of the body are to be included as external conditions, +are in continual change. Secondly, in cosmology, we must investigate +the conditions of all natural phenomena, internal as well as external, +as if they belonged to a chain infinite and without any prime or +supreme member, while we do not, on this account, deny the existence +of intelligible grounds of these phenomena, although we never employ +them to explain phenomena, for the simple reason that they are not +objects of our cognition. Thirdly, in the sphere of theology, we +must regard the whole system of possible experience as forming an +absolute, but dependent and sensuously-conditioned unity, and at the +same time as based upon a sole, supreme, and all-sufficient ground +existing apart from the world itself--a ground which is a +self-subsistent, primeval and creative reason, in relation to which +we so employ our reason in the field of experience, as if all objects +drew their origin from that archetype of all reason. In other words, +we ought not to deduce the internal phenomena of the mind from a +simple thinking substance, but deduce them from each other under the +guidance of the regulative idea of a simple being; we ought not to +deduce the phenomena, order, and unity of the universe from a +supreme intelligence, but merely draw from this idea of a supremely +wise cause the rules which must guide reason in its connection of +causes and effects. + +Now there is nothing to hinder us from admitting these ideas to +possess an objective and hyperbolic existence, except the cosmological +ideas, which lead reason into an antinomy: the psychological and +theological ideas are not antinomial. They contain no contradiction; +and how, then, can any one dispute their objective reality, since he +who denies it knows as little about their possibility as we who +affirm? And yet, when we wish to admit the existence of a thing, it +is not sufficient to convince ourselves that there is no positive +obstacle in the way; for it cannot be allowable to regard mere +creations of thought, which transcend, though they do not +contradict, all our conceptions, as real and determinate objects, +solely upon the authority of a speculative reason striving to +compass its own aims. They cannot, therefore, be admitted to be real +in themselves; they can only possess a comparative reality--that of +a schema of the regulative principle of the systematic unity of all +cognition. They are to be regarded not as actual things, but as in +some measure analogous to them. We abstract from the object of the +idea all the conditions which limit the exercise of our understanding, +but which, on the other hand, are the sole conditions of our +possessing a determinate conception of any given thing. And thus we +cogitate a something, of the real nature of which we have not the +least conception, but which we represent to ourselves as standing in +a relation to the whole system of phenomena, analogous to that in +which phenomena stand to each other. + +By admitting these ideal beings, we do not really extend our +cognitions beyond the objects of possible experience; we extend merely +the empirical unity of our experience, by the aid of systematic unity, +the schema of which is furnished by the idea, which is therefore +valid--not as a constitutive, but as a regulative principle. For +although we posit a thing corresponding to the idea--a something, an +actual existence--we do not on that account aim at the extension of +our cognition by means of transcendent conceptions. This existence +is purely ideal, and not objective; it is the mere expression of the +systematic unity which is to be the guide of reason in the field of +experience. There are no attempts made at deciding what the ground +of this unity may be, or what the real nature of this imaginary being. + +Thus the transcendental and only determinate conception of God, +which is presented to us by speculative reason, is in the strictest +sense deistic. In other words, reason does not assure us of the +objective validity of the conception; it merely gives us the idea of +something, on which the supreme and necessary unity of all +experience is based. This something we cannot, following the analogy +of a real substance, cogitate otherwise than as the cause of all +things operating in accordance with rational laws, if we regard it +as an individual object; although we should rest contented with the +idea alone as a regulative principle of reason, and make no attempt +at completing the sum of the conditions imposed by thought. This +attempt is, indeed, inconsistent with the grand aim of complete +systematic unity in the sphere of cognition--a unity to which no +bounds are set by reason. + +Hence it happens that, admitting a divine being, I can have no +conception of the internal possibility of its perfection, or of the +necessity of its existence. The only advantage of this admission is +that it enables me to answer all other questions relating to the +contingent, and to give reason the most complete satisfaction as +regards the unity which it aims at attaining in the world of +experience. But I cannot satisfy reason with regard to this hypothesis +itself; and this proves that it is not its intelligence and insight +into the subject, but its speculative interest alone which induces +it to proceed from a point lying far beyond the sphere of our +cognition, for the purpose of being able to consider all objects as +parts of a systematic whole. + +Here a distinction presents itself, in regard to the way in which we +may cogitate a presupposition--a distinction which is somewhat subtle, +but of great importance in transcendental philosophy. I may have +sufficient grounds to admit something, or the existence of +something, in a relative point of view (suppositio relativa), +without being justified in admitting it in an absolute sense +(suppositio absoluta). This distinction is undoubtedly requisite, in +the case of a regulative principle, the necessity of which we +recognize, though we are ignorant of the source and cause of that +necessity, and which we assume to be based upon some ultimate +ground, for the purpose of being able to cogitate the universality +of the principle in a more determinate way. For example, I cogitate +the existence of a being corresponding to a pure transcendental +idea. But I cannot admit that this being exists absolutely and in +itself, because all of the conceptions by which I can cogitate an +object in a determinate manner fall short of assuring me of its +existence; nay, the conditions of the objective validity of my +conceptions are excluded by the idea--by the very fact of its being +an idea. The conceptions of reality, substance, causality, nay, even +that of necessity in existence, have no significance out of the sphere +of empirical cognition, and cannot, beyond that sphere, determine any +object. They may, accordingly, be employed to explain the +possibility of things in the world of sense, but they are utterly +inadequate to explain the possibility of the universe itself +considered as a whole; because in this case the ground of +explanation must lie out of and beyond the world, and cannot, +therefore, be an object of possible experience. Now, I may admit the +existence of an incomprehensible being of this nature--the object of +a mere idea, relatively to the world of sense; although I have no ground +to admit its existence absolutely and in itself. For if an idea +(that of a systematic and complete unity, of which I shall presently +speak more particularly) lies at the foundation of the most extended +empirical employment of reason, and if this idea cannot be +adequately represented in concreto, although it is indispensably +necessary for the approximation of empirical unity to the highest +possible degree--I am not only authorized, but compelled, to realize +this idea, that is, to posit a real object corresponding thereto. +But I cannot profess to know this object; it is to me merely a +something, to which, as the ground of systematic unity in cognition, +I attribute such properties as are analogous to the conceptions employed +by the understanding in the sphere of experience. Following the +analogy of the notions of reality, substance, causality, and +necessity, I cogitate a being, which possesses all these attributes +in the highest degree; and, as this idea is the offspring of my reason +alone, I cogitate this being as self-subsistent reason, and as the +cause of the universe operating by means of ideas of the greatest +possible harmony and unity. Thus I abstract all conditions that +would limit my idea, solely for the purpose of rendering systematic +unity possible in the world of empirical diversity, and thus +securing the widest possible extension for the exercise of reason in +that sphere. This I am enabled to do, by regarding all connections +and relations in the world of sense, as if they were the dispositions +of a supreme reason, of which our reason is but a faint image. I then +proceed to cogitate this Supreme Being by conceptions which have, +properly, no meaning or application, except in the world of sense. +But as I am authorized to employ the transcendental hypothesis of such +a being in a relative respect alone, that is, as the substratum of +the greatest possible unity in experience--I may attribute to a being +which I regard as distinct from the world, such properties as belong +solely to the sphere of sense and experience. For I do not desire, +and am not justified in desiring, to cognize this object of my idea, +as it exists in itself; for I possess no conceptions sufficient for +or task, those of reality, substance, causality, nay, even that of +necessity in existence, losing all significance, and becoming merely +the signs of conceptions, without content and without applicability, +when I attempt to carry them beyond the limits of the world of sense. +I cogitate merely the relation of a perfectly unknown being to the +greatest possible systematic unity of experience, solely for the purpose +of employing it as the schema of the regulative principle which directs +reason in its empirical exercise. + +It is evident, at the first view, that we cannot presuppose the +reality of this transcendental object, by means of the conceptions +of reality, substance, causality, and so on, because these conceptions +cannot be applied to anything that is distinct from the world of +sense. Thus the supposition of a Supreme Being or cause is purely +relative; it is cogitated only in behalf of the systematic unity of +experience; such a being is but a something, of whose existence in +itself we have not the least conception. Thus, too, it becomes +sufficiently manifest why we required the idea of a necessary being +in relation to objects given by sense, although we can never have the +least conception of this being, or of its absolute necessity. + +And now we can clearly perceive the result of our transcendental +dialectic, and the proper aim of the ideas of pure reason--which +become dialectical solely from misunderstanding and inconsiderateness. +Pure reason is, in fact, occupied with itself, and not with any +object. Objects are not presented to it to be embraced in the unity +of an empirical conception; it is only the cognitions of the +understanding that are presented to it, for the purpose of receiving +the unity of a rational conception, that is, of being connected +according to a principle. The unity of reason is the unity of +system; and this systematic unity is not an objective principle, +extending its dominion over objects, but a subjective maxim, extending +its authority over the empirical cognition of objects. The +systematic connection which reason gives to the empirical employment +of the understanding not only advances the extension of that +employment, but ensures its correctness, and thus the principle of +a systematic unity of this nature is also objective, although only +in an indefinite respect (principium vagum). It is not, however, a +constitutive principle, determining an object to which it directly +relates; it is merely a regulative principle or maxim, advancing and +strengthening the empirical exercise of reason, by the opening up of +new paths of which the understanding is ignorant, while it never +conflicts with the laws of its exercise in the sphere of experience. + +But reason cannot cogitate this systematic unity, without at the +same time cogitating an object of the idea--an object that cannot be +presented in any experience, which contains no concrete example of +a complete systematic unity. This being (ens rationis ratiocinatae) +is therefore a mere idea and is not assumed to be a thing which is +real absolutely and in itself. On the contrary, it forms merely the +problematical foundation of the connection which the mind introduces +among the phenomena of the sensuous world. We look upon this +connection, in the light of the above-mentioned idea, as if it drew +its origin from the supposed being which corresponds to the idea. +And yet all we aim at is the possession of this idea as a secure +foundation for the systematic unity of experience--a unity +indispensable to reason, advantageous to the understanding, and +promotive of the interests of empirical cognition. + +We mistake the true meaning of this idea when we regard it as an +enouncement, or even as a hypothetical declaration of the existence +of a real thing, which we are to regard as the origin or ground of +a systematic constitution of the universe. On the contrary, it is left +completely undetermined what the nature or properties of this +so-called ground may be. The idea is merely to be adopted as a point +of view, from which this unity, so essential to reason and so +beneficial to the understanding, may be regarded as radiating. In +one word, this transcendental thing is merely the schema of a +regulative principle, by means of which Reason, so far as in her lies, +extends the dominion of systematic unity over the whole sphere of +experience. + +The first object of an idea of this kind is the ego, considered +merely as a thinking nature or soul. If I wish to investigate the +properties of a thinking being, I must interrogate experience. But +I find that I can apply none of the categories to this object, the +schema of these categories, which is the condition of their +application, being given only in sensuous intuition. But I cannot thus +attain to the cognition of a systematic unity of all the phenomena +of the internal sense. Instead, therefore, of an empirical +conception of what the soul really is, reason takes the conception +of the empirical unity of all thought, and, by cogitating this unity +as unconditioned and primitive, constructs the rational conception +or idea of a simple substance which is in itself unchangeable, +possessing personal identity, and in connection with other real things +external to it; in one word, it constructs the idea of a simple +self-subsistent intelligence. But the real aim of reason in this +procedure is the attainment of principles of systematic unity for +the explanation of the phenomena of the soul. That is, reason +desires to be able to represent all the determinations of the internal +sense as existing in one subject, all powers as deduced from one +fundamental power, all changes as mere varieties in the condition of +a being which is permanent and always the same, and all phenomena in +space as entirely different in their nature from the procedure of +thought. Essential simplicity (with the other attributes predicated +of the ego) is regarded as the mere schema of this regulative +principle; it is not assumed that it is the actual ground of the +properties of the soul. For these properties may rest upon quite +different grounds, of which we are completely ignorant; just as the +above predicates could not give us any knowledge of the soul as it +is in itself, even if we regarded them as valid in respect of it, +inasmuch as they constitute a mere idea, which cannot be represented +in concreto. Nothing but good can result from a psychological idea +of this kind, if we only take proper care not to consider it as more +than an idea; that is, if we regard it as valid merely in relation +to the employment of reason, in the sphere of the phenomena of the +soul. Under the guidance of this idea, or principle, no empirical laws +of corporeal phenomena are called in to explain that which is a +phenomenon of the internal sense alone; no windy hypotheses of the +generation, annihilation, and palingenesis of souls are admitted. Thus +the consideration of this object of the internal sense is kept pure, +and unmixed with heterogeneous elements; while the investigation of +reason aims at reducing all the grounds of explanation employed in +this sphere of knowledge to a single principle. All this is best +effected, nay, cannot be effected otherwise than by means of such a +schema, which requires us to regard this ideal thing as an actual +existence. The psychological idea is, therefore, meaningless and +inapplicable, except as the schema of a regulative conception. For, +if I ask whether the soul is not really of a spiritual nature--it is +a question which has no meaning. From such a conception has been +abstracted, not merely all corporeal nature, but all nature, that +is, all the predicates of a possible experience; and consequently, +all the conditions which enable us to cogitate an object to this +conception have disappeared. But, if these conditions are absent, it +is evident that the conception is meaningless. + +The second regulative idea of speculative reason is the conception +of the universe. For nature is properly the only object presented to +us, in regard to which reason requires regulative principles. Nature +is twofold--thinking and corporeal nature. To cogitate the latter in +regard to its internal possibility, that is, to determine the +application of the categories to it, no idea is required--no +representation which transcends experience. In this sphere, therefore, +an idea is impossible, sensuous intuition being our only guide; while, +in the sphere of psychology, we require the fundamental idea (I), +which contains a priori a certain form of thought namely, the unity +of the ego. Pure reason has, therefore, nothing left but nature in +general, and the completeness of conditions in nature in accordance +with some principle. The absolute totality of the series of these +conditions is an idea, which can never be fully realized in the +empirical exercise of reason, while it is serviceable as a rule for +the procedure of reason in relation to that totality. It requires +us, in the explanation of given phenomena (in the regress or ascent +in the series), to proceed as if the series were infinite in itself, +that is, were prolonged in indefinitum,; while on the other hand, where +reason is regarded as itself the determining cause (in the region of +freedom), we are required to proceed as if we had not before us an +object of sense, but of the pure understanding. In this latter case, +the conditions do not exist in the series of phenomena, but may be +placed quite out of and beyond it, and the series of conditions may +be regarded as if it had an absolute beginning from an intelligible +cause. All this proves that the cosmological ideas are nothing but +regulative principles, and not constitutive; and that their aim is +not to realize an actual totality in such series. The full discussion +of this subject will be found in its proper place in the chapter on +the antinomy of pure reason. + +The third idea of pure reason, containing the hypothesis of a +being which is valid merely as a relative hypothesis, is that of the +one and all-sufficient cause of all cosmological series, in other +words, the idea of God. We have not the slightest ground absolutely +to admit the existence of an object corresponding to this idea; for +what can empower or authorize us to affirm the existence of a being +of the highest perfection--a being whose existence is absolutely +necessary--merely because we possess the conception of such a being? +The answer is: It is the existence of the world which renders this +hypothesis necessary. But this answer makes it perfectly evident +that the idea of this being, like all other speculative ideas, is +essentially nothing more than a demand upon reason that it shall +regulate the connection which it and its subordinate faculties +introduce into the phenomena of the world by principles of +systematic unity and, consequently, that it shall regard all phenomena +as originating from one all-embracing being, as the supreme and +all-sufficient cause. From this it is plain that the only aim of +reason in this procedure is the establishment of its own formal rule +for the extension of its dominion in the world of experience; that +it does not aim at an extension of its cognition beyond the limits +of experience; and that, consequently, this idea does not contain +any constitutive principle. + +The highest formal unity, which is based upon ideas alone, is the +unity of all things--a unity in accordance with an aim or purpose; +and the speculative interest of reason renders it necessary to regard +all order in the world as if it originated from the intention and +design of a supreme reason. This principle unfolds to the view of +reason in the sphere of experience new and enlarged prospects, and +invites it to connect the phenomena of the world according to +teleological laws, and in this way to attain to the highest possible +degree of systematic unity. The hypothesis of a supreme +intelligence, as the sole cause of the universe--an intelligence which +has for us no more than an ideal existence--is accordingly always of +the greatest service to reason. Thus, if we presuppose, in relation +to the figure of the earth (which is round, but somewhat flattened +at the poles),* or that of mountains or seas, wise designs on the part +of an author of the universe, we cannot fail to make, by the light +of this supposition, a great number of interesting discoveries. If +we keep to this hypothesis, as a principle which is purely regulative, +even error cannot be very detrimental. For, in this case, error can +have no more serious consequences than that, where we expected to +discover a teleological connection (nexus finalis), only a +mechanical or physical connection appears. In such a case, we merely +fail to find the additional form of unity we expected, but we do not +lose the rational unity which the mind requires in its procedure in +experience. But even a miscarriage of this sort cannot affect the +law in its general and teleological relations. For although we may +convict an anatomist of an error, when he connects the limb of some +animal with a certain purpose, it is quite impossible to prove in a +single case that any arrangement of nature, be it what it may, is +entirely without aim or design. And thus medical physiology, by the +aid of a principle presented to it by pure reason, extends its very +limited empirical knowledge of the purposes of the different parts +of an organized body so far that it may be asserted with the utmost +confidence, and with the approbation of all reflecting men, that every +organ or bodily part of an animal has its use and answers a certain +design. Now, this is a supposition which, if regarded as of a +constitutive character, goes much farther than any experience or +observation of ours can justify. Hence it is evident that it is +nothing more than a regulative principle of reason, which aims at +the highest degree of systematic unity, by the aid of the idea of a +causality according to design in a supreme cause--a cause which it +regards as the highest intelligence. + +[*Footnote: The advantages which a circular form, in the case of the +earth, has over every other, are well known. But few are aware that +the slight flattening at the poles, which gives it the figure of a +spheroid, is the only cause which prevents the elevations of continents +or even of mountains, perhaps thrown up by some internal convulsion, +from continually altering the position of the axis of the earth--and +that to some considerable degree in a short time. The great protuberance +of the earth under the Equator serves to overbalance the impetus of +all other masses of earth, and thus to preserve the axis of the earth, +so far as we can observe, in its present position. And yet this wise +arrangement has been unthinkingly explained from the equilibrium of +the formerly fluid mass.] + +If, however, we neglect this restriction of the idea to a purely +regulative influence, reason is betrayed into numerous errors. For +it has then left the ground of experience, in which alone are to be +found the criteria of truth, and has ventured into the region of the +incomprehensible and unsearchable, on the heights of which it loses +its power and collectedness, because it has completely severed its +connection with experience. + +The first error which arises from our employing the idea of a +Supreme Being as a constitutive (in repugnance to the very nature of +an idea), and not as a regulative principle, is the error of +inactive reason (ignava ratio).* We may so term every principle +which requires us to regard our investigations of nature as absolutely +complete, and allows reason to cease its inquiries, as if it had fully +executed its task. Thus the psychological idea of the ego, when +employed as a constitutive principle for the explanation of the +phenomena of the soul, and for the extension of our knowledge +regarding this subject beyond the limits of experience--even to the +condition of the soul after death--is convenient enough for the +purposes of pure reason, but detrimental and even ruinous to its +interests in the sphere of nature and experience. The dogmatizing +spiritualist explains the unchanging unity of our personality +through all changes of condition from the unity of a thinking +substance, the interest which we take in things and events that can +happen only after our death, from a consciousness of the immaterial +nature of our thinking subject, and so on. Thus he dispenses with +all empirical investigations into the cause of these internal +phenomena, and with all possible explanations of them upon purely +natural grounds; while, at the dictation of a transcendent reason, +he passes by the immanent sources of cognition in experience, +greatly to his own ease and convenience, but to the sacrifice of +all, genuine insight and intelligence. These prejudicial +consequences become still more evident, in the case of the +dogmatical treatment of our idea of a Supreme Intelligence, and the +theological system of nature (physico-theology) which is falsely based +upon it. For, in this case, the aims which we observe in nature, and +often those which we merely fancy to exist, make the investigation +of causes a very easy task, by directing us to refer such and such +phenomena immediately to the unsearchable will and counsel of the +Supreme Wisdom, while we ought to investigate their causes in the +general laws of the mechanism of matter. We are thus recommended to +consider the labour of reason as ended, when we have merely +dispensed with its employment, which is guided surely and safely +only by the order of nature and the series of changes in the world- +which are arranged according to immanent and general laws. This +error may be avoided, if we do not merely consider from the view-point +of final aims certain parts of nature, such as the division and +structure of a continent, the constitution and direction of certain +mountain-chains, or even the organization existing in the vegetable +and animal kingdoms, but look upon this systematic unity of nature +in a perfectly general way, in relation to the idea of a Supreme +Intelligence. If we pursue this advice, we lay as a foundation for +all investigation the conformity to aims of all phenomena of nature +in accordance with universal laws, for which no particular arrangement +of nature is exempt, but only cognized by us with more or less +difficulty; and we possess a regulative principle of the systematic +unity of a teleological connection, which we do not attempt to +anticipate or predetermine. All that we do, and ought to do, is to +follow out the physico-mechanical connection in nature according to +general laws, with the hope of discovering, sooner or later, the +teleological connection also. Thus, and thus only, can the principle +of final unity aid in the extension of the employment of reason in +the sphere of experience, without being in any case detrimental to +its interests. + +[*Footnote: This was the term applied by the old dialecticians to a +sophistical argument, which ran thus: If it is your fate to die of +this disease, you will die, whether you employ a physician or not. +Cicero says that this mode of reasoning has received this appellation, +because, if followed, it puts an end to the employment of reason in +the affairs of life. For a similar reason, I have applied this designation +to the sophistical argument of pure reason.] + +The second error which arises from the misconception of the +principle of systematic unity is that of perverted reason (perversa +ratio, usteron roteron rationis). The idea of systematic unity is +available as a regulative principle in the connection of phenomena +according to general natural laws; and, how far soever we have to +travel upon the path of experience to discover some fact or event, +this idea requires us to believe that we have approached all the +more nearly to the completion of its use in the sphere of nature, +although that completion can never be attained. But this error +reverses the procedure of reason. We begin by hypostatizing the +principle of systematic unity, and by giving an anthropomorphic +determination to the conception of a Supreme Intelligence, and then +proceed forcibly to impose aims upon nature. Thus not only does +teleology, which ought to aid in the completion of unity in accordance +with general laws, operate to the destruction of its influence, but +it hinders reason from attaining its proper aim, that is, the proof, +upon natural grounds, of the existence of a supreme intelligent cause. +For, if we cannot presuppose supreme finality in nature a priori, that +is, as essentially belonging to nature, how can we be directed to +endeavour to discover this unity and, rising gradually through its +different degrees, to approach the supreme perfection of an author +of all--a perfection which is absolutely necessary, and therefore +cognizable a priori? The regulative principle directs us to presuppose +systematic unity absolutely and, consequently, as following from the +essential nature of things--but only as a unity of nature, not +merely cognized empirically, but presupposed a priori, although only +in an indeterminate manner. But if I insist on basing nature upon +the foundation of a supreme ordaining Being, the unity of nature is +in effect lost. For, in this case, it is quite foreign and unessential +to the nature of things, and cannot be cognized from the general laws +of nature. And thus arises a vicious circular argument, what ought +to have been proved having been presupposed. + +To take the regulative principle of systematic unity in nature for +a constitutive principle, and to hypostatize and make a cause out of +that which is properly the ideal ground of the consistent and +harmonious exercise of reason, involves reason in inextricable +embarrassments. The investigation of nature pursues its own path under +the guidance of the chain of natural causes, in accordance with the +general laws of nature, and ever follows the light of the idea of an +author of the universe--not for the purpose of deducing the +finality, which it constantly pursues, from this Supreme Being, but +to attain to the cognition of his existence from the finality which +it seeks in the existence of the phenomena of nature, and, if possible, +in that of all things to cognize this being, consequently, as +absolutely necessary. Whether this latter purpose succeed or not, +the idea is and must always be a true one, and its employment, when +merely regulative, must always be accompanied by truthful and +beneficial results. + +Complete unity, in conformity with aims, constitutes absolute +perfection. But if we do not find this unity in the nature of the +things which go to constitute the world of experience, that is, of +objective cognition, consequently in the universal and necessary +laws of nature, how can we infer from this unity the idea of the +supreme and absolutely necessary perfection of a primal being, which +is the origin of all causality? The greatest systematic unity, and +consequently teleological unity, constitutes the very foundation of +the possibility of the most extended employment of human reason. The +idea of unity is therefore essentially and indissolubly connected with +the nature of our reason. This idea is a legislative one; and hence +it is very natural that we should assume the existence of a legislative +reason corresponding to it, from which the systematic unity of nature- +the object of the operations of reason--must be derived. + +In the course of our discussion of the antinomies, we stated that it +is always possible to answer all the questions which pure reason may +raise; and that the plea of the limited nature of our cognition, which +is unavoidable and proper in many questions regarding natural +phenomena, cannot in this case be admitted, because the questions +raised do not relate to the nature of things, but are necessarily +originated by the nature of reason itself, and relate to its own +internal constitution. We can now establish this assertion, which at +first sight appeared so rash, in relation to the two questions in +which reason takes the greatest interest, and thus complete our +discussion of the dialectic of pure reason. + +If, then, the question is asked, in relation to transcendental +theology,* first, whether there is anything distinct from the world, +which contains the ground of cosmical order and connection according +to general laws? The answer is: Certainly. For the world is a sum of +phenomena; there must, therefore, be some transcendental basis of +these phenomena, that is, a basis cogitable by the pure +understanding alone. If, secondly, the question is asked whether +this being is substance, whether it is of the greatest reality, +whether it is necessary, and so forth? I answer that this question +is utterly without meaning. For all the categories which aid me in +forming a conception of an object cannot be employed except in the +world of sense, and are without meaning when not applied to objects +of actual or possible experience. Out of this sphere, they are not +properly conceptions, but the mere marks or indices of conceptions, +which we may admit, although they cannot, without the help of +experience, help us to understand any subject or thing. If, thirdly, +the question is whether we may not cogitate this being, which is +distinct from the world, in analogy with the objects of experience? +The answer is: Undoubtedly, but only as an ideal, and not as a real +object. That is, we must cogitate it only as an unknown substratum +of the systematic unity, order, and finality of the world--a unity +which reason must employ as the regulative principle of its +investigation of nature. Nay, more, we may admit into the idea certain +anthropomorphic elements, which are promotive of the interests of this +regulative principle. For it is no more than an idea, which does not +relate directly to a being distinct from the world, but to the +regulative principle of the systematic unity of the world, by means, +however, of a schema of this unity--the schema of a Supreme +Intelligence, who is the wisely-designing author of the universe. What +this basis of cosmical unity may be in itself, we know not--we +cannot discover from the idea; we merely know how we ought to employ +the idea of this unity, in relation to the systematic operation of +reason in the sphere of experience. + +[*Footnote: After what has been said of the psychological idea of the +ego and its proper employment as a regulative principle of the operations +of reason, I need not enter into details regarding the transcendental +illusion by which the systematic unity of all the various phenomena +of the internal sense is hypostatized. The procedure is in this case +very similar to that which has been discussed in our remarks on the +theological ideal.] + +But, it will be asked again, can we on these grounds, admit the +existence of a wise and omnipotent author of the world? Without doubt; +and not only so, but we must assume the existence of such a being. +But do we thus extend the limits of our knowledge beyond the field +of possible experience? By no means. For we have merely presupposed +a something, of which we have no conception, which we do not know as +it is in itself; but, in relation to the systematic disposition of +the universe, which we must presuppose in all our observation of nature, +we have cogitated this unknown being in analogy with an intelligent +existence (an empirical conception), that is to say, we have endowed +it with those attributes, which, judging from the nature of our own +reason, may contain the ground of such a systematic unity. This idea +is therefore valid only relatively to the employment in experience +of our reason. But if we attribute to it absolute and objective +validity, we overlook the fact that it is merely an ideal being that +we cogitate; and, by setting out from a basis which is not +determinable by considerations drawn from experience, we place +ourselves in a position which incapacitates us from applying this +principle to the empirical employment of reason. + +But, it will be asked further, can I make any use of this conception +and hypothesis in my investigations into the world and nature? Yes, +for this very purpose was the idea established by reason as a +fundamental basis. But may I regard certain arrangements, which seemed +to have been made in conformity with some fixed aim, as the +arrangements of design, and look upon them as proceeding from the +divine will, with the intervention, however, of certain other +particular arrangements disposed to that end? Yes, you may do so; +but at the same time you must regard it as indifferent, whether it +is asserted that divine wisdom has disposed all things in conformity +with his highest aims, or that the idea of supreme wisdom is a +regulative principle in the investigation of nature, and at the same +time a principle of the systematic unity of nature according to +general laws, even in those cases where we are unable to discover that +unity. In other words, it must be perfectly indifferent to you whether +you say, when you have discovered this unity: God has wisely willed +it so; or: Nature has wisely arranged this. For it was nothing but +the systematic unity, which reason requires as a basis for the +investigation of nature, that justified you in accepting the idea of +a supreme intelligence as a schema for a regulative principle; and, +the farther you advance in the discovery of design and finality, the +more certain the validity of your idea. But, as the whole aim of +this regulative principle was the discovery of a necessary and +systematic unity in nature, we have, in so far as we attain this, to +attribute our success to the idea of a Supreme Being; while, at the +same time, we cannot, without involving ourselves in contradictions, +overlook the general laws of nature, as it was in reference to them +alone that this idea was employed. We cannot, I say, overlook the +general laws of nature, and regard this conformity to aims +observable in nature as contingent or hyperphysical in its origin; +inasmuch as there is no ground which can justify us in the admission +of a being with such properties distinct from and above nature. All +that we are authorized to assert is that this idea may be employed +as a principle, and that the properties of the being which is +assumed to correspond to it may be regarded as systematically +connected in analogy with the causal determination of phenomena. + +For the same reasons we are justified in introducing into the idea +of the supreme cause other anthropomorphic elements (for without these +we could not predicate anything of it); we may regard it as +allowable to cogitate this cause as a being with understanding, the +feelings of pleasure and displeasure, and faculties of desire and will +corresponding to these. At the same time, we may attribute to this +being infinite perfection--a perfection which necessarily transcends +that which our knowledge of the order and design in the world +authorize us to predicate of it. For the regulative law of +systematic unity requires us to study nature on the supposition that +systematic and final unity in infinitum is everywhere discoverable, +even in the highest diversity. For, although we may discover little +of this cosmical perfection, it belongs to the legislative prerogative +of reason to require us always to seek for and to expect it; while +it must always be beneficial to institute all inquiries into nature +in accordance with this principle. But it is evident that, by this +idea of a supreme author of all, which I place as the foundation of +all inquiries into nature, I do not mean to assert the existence of +such a being, or that I have any knowledge of its existence; and, +consequently, I do not really deduce anything from the existence of +this being, but merely from its idea, that is to say, from the +nature of things in this world, in accordance with this idea. A +certain dim consciousness of the true use of this idea seems to have +dictated to the philosophers of all times the moderate language used +by them regarding the cause of the world. We find them employing the +expressions wisdom and care of nature, and divine wisdom, as +synonymous--nay, in purely speculative discussions, preferring the +former, because it does not carry the appearance of greater +pretensions than such as we are entitled to make, and at the same time +directs reason to its proper field of action--nature and her +phenomena. + +Thus, pure reason, which at first seemed to promise us nothing +less than the extension of our cognition beyond the limits of +experience, is found, when thoroughly examined, to contain nothing +but regulative principles, the virtue and function of which is to +introduce into our cognition a higher degree of unity than the +understanding could of itself. These principles, by placing the goal +of all our struggles at so great a distance, realize for us the most +thorough connection between the different parts of our cognition, +and the highest degree of systematic unity. But, on the other hand, +if misunderstood and employed as constitutive principles of +transcendent cognition, they become the parents of illusions and +contradictions, while pretending to introduce us to new regions of +knowledge. + +Thus all human cognition begins with intuitions, proceeds from +thence to conceptions, and ends with ideas. Although it possesses, +in relation to all three elements, a priori sources of cognition, +which seemed to transcend the limits of all experience, a +thoroughgoing criticism demonstrates that speculative reason can +never, by the aid of these elements, pass the bounds of possible +experience, and that the proper destination of this highest faculty +of cognition is to employ all methods, and all the principles of these +methods, for the purpose of penetrating into the innermost secrets +of nature, by the aid of the principles of unity (among all kinds of +which teleological unity is the highest), while it ought not to +attempt to soar above the sphere of experience, beyond which there +lies nought for us but the void inane. The critical examination, in +our Transcendental Analytic, of all the propositions which professed +to extend cognition beyond the sphere of experience, completely +demonstrated that they can only conduct us to a possible experience. +If we were not distrustful even of the clearest abstract theorems, +if we were not allured by specious and inviting prospects to escape +from the constraining power of their evidence, we might spare +ourselves the laborious examination of all the dialectical arguments +which a transcendent reason adduces in support of its pretensions; +for we should know with the most complete certainty that, however honest +such professions might be, they are null and valueless, because they +relate to a kind of knowledge to which no man can by any possibility +attain. But, as there is no end to discussion, if we cannot discover +the true cause of the illusions by which even the wisest are deceived, +and as the analysis of all our transcendent cognition into its +elements is of itself of no slight value as a psychological study, +while it is a duty incumbent on every philosopher--it was found +necessary to investigate the dialectical procedure of reason in its +primary sources. And as the inferences of which this dialectic is +the parent are not only deceitful, but naturally possess a profound +interest for humanity, it was advisable at the same time, to give a +full account of the momenta of this dialectical procedure, and to +deposit it in the archives of human reason, as a warning to all future +metaphysicians to avoid these causes of speculative error. + + + +II. + +TRANSCENDENTAL DOCTRINE OF METHOD. + +If we regard the sum of the cognition of pure speculative reason +as an edifice, the idea of which, at least, exists in the human +mind, it may be said that we have in the Transcendental Doctrine of +Elements examined the materials and determined to what edifice these +belong, and what its height and stability. We have found, indeed, +that, although we had purposed to build for ourselves a tower which +should reach to Heaven, the supply of materials sufficed merely for +a habitation, which was spacious enough for all terrestrial +purposes, and high enough to enable us to survey the level plain of +experience, but that the bold undertaking designed necessarily +failed for want of materials--not to mention the confusion of tongues, +which gave rise to endless disputes among the labourers on the plan +of the edifice, and at last scattered them over all the world, each +to erect a separate building for himself, according to his own plans +and his own inclinations. Our present task relates not to the +materials, but to the plan of an edifice; and, as we have had +sufficient warning not to venture blindly upon a design which may be +found to transcend our natural powers, while, at the same time, we +cannot give up the intention of erecting a secure abode for the +mind, we must proportion our design to the material which is presented +to us, and which is, at the same time, sufficient for all our wants. + +I understand, then, by the transcendental doctrine of method, the +determination of the formal conditions of a complete system of pure +reason. We shall accordingly have to treat of the discipline, the +canon, the architectonic, and, finally, the history of pure reason. +This part of our Critique will accomplish, from the transcendental +point of view, what has been usually attempted, but miserably +executed, under the name of practical logic. It has been badly +executed, I say, because general logic, not being limited to any +particular kind of cognition (not even to the pure cognition of the +understanding) nor to any particular objects, it cannot, without +borrowing from other sciences, do more than present merely the +titles or signs of possible methods and the technical expressions, +which are employed in the systematic parts of all sciences; and thus +the pupil is made acquainted with names, the meaning and application +of which he is to learn only at some future time. + + + +CHAPTER I. The Discipline of Pure Reason. + +Negative judgements--those which are so not merely as regards +their logical form, but in respect of their content--are not +commonly held in especial respect. They are, on the contrary, regarded +as jealous enemies of our insatiable desire for knowledge; and it +almost requires an apology to induce us to tolerate, much less to +prize and to respect them. + +All propositions, indeed, may be logically expressed in a negative +form; but, in relation to the content of our cognition, the peculiar +province of negative judgements is solely to prevent error. For this +reason, too, negative propositions, which are framed for the purpose +of correcting false cognitions where error is absolutely impossible, +are undoubtedly true, but inane and senseless; that is, they are in +reality purposeless and, for this reason, often very ridiculous. +Such is the proposition of the schoolman that Alexander could not have +subdued any countries without an army. + +But where the limits of our possible cognition are very much +contracted, the attraction to new fields of knowledge great, the +illusions to which the mind is subject of the most deceptive +character, and the evil consequences of error of no inconsiderable +magnitude--the negative element in knowledge, which is useful only +to guard us against error, is of far more importance than much of that +positive instruction which makes additions to the sum of our +knowledge. The restraint which is employed to repress, and finally +to extirpate the constant inclination to depart from certain rules, +is termed discipline. It is distinguished from culture, which aims +at the formation of a certain degree of skill, without attempting to +repress or to destroy any other mental power, already existing. In +the cultivation of a talent, which has given evidence of an impulse +towards self-development, discipline takes a negative,* culture and +doctrine a positive, part. + + +[*Footnote: I am well aware that, in the language of the schools, the +term discipline is usually employed as synonymous with instruction. +But there are so many cases in which it is necessary to distinguish +the notion of the former, as a course of corrective training, from +that of the latter, as the communication of knowledge, and the nature +of things itself demands the appropriation of the most suitable +expressions for this distinction, that it is my desire that the former +terms should never be employed in any other than a negative +signification.] + + +That natural dispositions and talents (such as imagination and wit), +which ask a free and unlimited development, require in many respects +the corrective influence of discipline, every one will readily +grant. But it may well appear strange that reason, whose proper duty +it is to prescribe rules of discipline to all the other powers of +the mind, should itself require this corrective. It has, in fact, +hitherto escaped this humiliation, only because, in presence of its +magnificent pretensions and high position, no one could readily +suspect it to be capable of substituting fancies for conceptions, +and words for things. + +Reason, when employed in the field of experience, does not stand +in need of criticism, because its principles are subjected to the +continual test of empirical observations. Nor is criticism requisite +in the sphere of mathematics, where the conceptions of reason must +always be presented in concreto in pure intuition, and baseless or +arbitrary assertions are discovered without difficulty. But where +reason is not held in a plain track by the influence of empirical or +of pure intuition, that is, when it is employed in the +transcendental sphere of pure conceptions, it stands in great need +of discipline, to restrain its propensity to overstep the limits of +possible experience and to keep it from wandering into error. In fact, +the utility of the philosophy of pure reason is entirely of this +negative character. Particular errors may be corrected by particular +animadversions, and the causes of these errors may be eradicated by +criticism. But where we find, as in the case of pure reason, a +complete system of illusions and fallacies, closely connected with +each other and depending upon grand general principles, there seems +to be required a peculiar and negative code of mental legislation, +which, under the denomination of a discipline, and founded upon the +nature of reason and the objects of its exercise, shall constitute +a system of thorough examination and testing, which no fallacy will +be able to withstand or escape from, under whatever disguise or +concealment it may lurk. + +But the reader must remark that, in this the second division of +our transcendental Critique the discipline of pure reason is not +directed to the content, but to the method of the cognition of pure +reason. The former task has been completed in the doctrine of +elements. But there is so much similarity in the mode of employing +the faculty of reason, whatever be the object to which it is applied, +while, at the same time, its employment in the transcendental sphere +is so essentially different in kind from every other, that, without +the warning negative influence of a discipline specially directed to +that end, the errors are unavoidable which spring from the +unskillful employment of the methods which are originated by reason +but which are out of place in this sphere. + + + +SECTION I. The Discipline of Pure Reason in the Sphere of Dogmatism. + +The science of mathematics presents the most brilliant example of +the extension of the sphere of pure reason without the aid of +experience. Examples are always contagious; and they exert an especial +influence on the same faculty, which naturally flatters itself that +it will have the same good fortune in other case as fell to its lot +in one fortunate instance. Hence pure reason hopes to be able to extend +its empire in the transcendental sphere with equal success and +security, especially when it applies the same method which was +attended with such brilliant results in the science of mathematics. +It is, therefore, of the highest importance for us to know whether +the method of arriving at demonstrative certainty, which is termed +mathematical, be identical with that by which we endeavour to attain +the same degree of certainty in philosophy, and which is termed in +that science dogmatical. + +Philosophical cognition is the cognition of reason by means of +conceptions; mathematical cognition is cognition by means of the +construction of conceptions. The construction of a conception is the +presentation a priori of the intuition which corresponds to the +conception. For this purpose a non-empirical intuition is requisite, +which, as an intuition, is an individual object; while, as the +construction of a conception (a general representation), it must be +seen to be universally valid for all the possible intuitions which +rank under that conception. Thus I construct a triangle, by the +presentation of the object which corresponds to this conception, +either by mere imagination, in pure intuition, or upon paper, in +empirical intuition, in both cases completely a priori, without +borrowing the type of that figure from any experience. The +individual figure drawn upon paper is empirical; but it serves, +notwithstanding, to indicate the conception, even in its universality, +because in this empirical intuition we keep our eye merely on the +act of the construction of the conception, and pay no attention to +the various modes of determining it, for example, its size, the length +of its sides, the size of its angles, these not in the least affecting +the essential character of the conception. + +Philosophical cognition, accordingly, regards the particular only in +the general; mathematical the general in the particular, nay, in the +individual. This is done, however, entirely a priori and by means of +pure reason, so that, as this individual figure is determined under +certain universal conditions of construction, the object of the +conception, to which this individual figure corresponds as its schema, +must be cogitated as universally determined. + +The essential difference of these two modes of cognition consists, +therefore, in this formal quality; it does not regard the difference +of the matter or objects of both. Those thinkers who aim at +distinguishing philosophy from mathematics by asserting that the +former has to do with quality merely, and the latter with quantity, +have mistaken the effect for the cause. The reason why mathematical +cognition can relate only to quantity is to be found in its form +alone. For it is the conception of quantities only that is capable +of being constructed, that is, presented a priori in intuition; +while qualities cannot be given in any other than an empirical +intuition. Hence the cognition of qualities by reason is possible only +through conceptions. No one can find an intuition which shall +correspond to the conception of reality, except in experience; it +cannot be presented to the mind a priori and antecedently to the +empirical consciousness of a reality. We can form an intuition, by +means of the mere conception of it, of a cone, without the aid of +experience; but the colour of the cone we cannot know except from +experience. I cannot present an intuition of a cause, except in an +example which experience offers to me. Besides, philosophy, as well +as mathematics, treats of quantities; as, for example, of totality, +infinity, and so on. Mathematics, too, treats of the difference of +lines and surfaces--as spaces of different quality, of the +continuity of extension--as a quality thereof. But, although in such +cases they have a common object, the mode in which reason considers +that object is very different in philosophy from what it is in +mathematics. The former confines itself to the general conceptions; +the latter can do nothing with a mere conception, it hastens to +intuition. In this intuition it regards the conception in concreto, +not empirically, but in an a priori intuition, which it has +constructed; and in which, all the results which follow from the +general conditions of the construction of the conception are in all +cases valid for the object of the constructed conception. + +Suppose that the conception of a triangle is given to a +philosopher and that he is required to discover, by the +philosophical method, what relation the sum of its angles bears to +a right angle. He has nothing before him but the conception of a +figure enclosed within three right lines, and, consequently, with +the same number of angles. He may analyse the conception of a right +line, of an angle, or of the number three as long as he pleases, but +he will not discover any properties not contained in these +conceptions. But, if this question is proposed to a geometrician, he +at once begins by constructing a triangle. He knows that two right +angles are equal to the sum of all the contiguous angles which proceed +from one point in a straight line; and he goes on to produce one +side of his triangle, thus forming two adjacent angles which are +together equal to two right angles. He then divides the exterior of +these angles, by drawing a line parallel with the opposite side of +the triangle, and immediately perceives that he has thus got an exterior +adjacent angle which is equal to the interior. Proceeding in this way, +through a chain of inferences, and always on the ground of +intuition, he arrives at a clear and universally valid solution of +the question. + +But mathematics does not confine itself to the construction of +quantities (quanta), as in the case of geometry; it occupies itself +with pure quantity also (quantitas), as in the case of algebra, +where complete abstraction is made of the properties of the object +indicated by the conception of quantity. In algebra, a certain +method of notation by signs is adopted, and these indicate the +different possible constructions of quantities, the extraction of +roots, and so on. After having thus denoted the general conception +of quantities, according to their different relations, the different +operations by which quantity or number is increased or diminished +are presented in intuition in accordance with general rules. Thus, +when one quantity is to be divided by another, the signs which +denote both are placed in the form peculiar to the operation of +division; and thus algebra, by means of a symbolical construction of +quantity, just as geometry, with its ostensive or geometrical +construction (a construction of the objects themselves), arrives at +results which discursive cognition cannot hope to reach by the aid +of mere conceptions. + +Now, what is the cause of this difference in the fortune of the +philosopher and the mathematician, the former of whom follows the path +of conceptions, while the latter pursues that of intuitions, which +he represents, a priori, in correspondence with his conceptions? The +cause is evident from what has been already demonstrated in the +introduction to this Critique. We do not, in the present case, want +to discover analytical propositions, which may be produced merely by +analysing our conceptions--for in this the philosopher would have +the advantage over his rival; we aim at the discovery of synthetical +propositions--such synthetical propositions, moreover, as can be +cognized a priori. I must not confine myself to that which I +actually cogitate in my conception of a triangle, for this is +nothing more than the mere definition; I must try to go beyond that, +and to arrive at properties which are not contained in, although +they belong to, the conception. Now, this is impossible, unless I +determine the object present to my mind according to the conditions, +either of empirical, or of pure, intuition. In the former case, I +should have an empirical proposition (arrived at by actual measurement +of the angles of the triangle), which would possess neither +universality nor necessity; but that would be of no value. In the +latter, I proceed by geometrical construction, by means of which I +collect, in a pure intuition, just as I would in an empirical +intuition, all the various properties which belong to the schema of +a triangle in general, and consequently to its conception, and thus +construct synthetical propositions which possess the attribute of +universality. + +It would be vain to philosophize upon the triangle, that is, to +reflect on it discursively; I should get no further than the +definition with which I had been obliged to set out. There are +certainly transcendental synthetical propositions which are framed +by means of pure conceptions, and which form the peculiar +distinction of philosophy; but these do not relate to any particular +thing, but to a thing in general, and enounce the conditions under +which the perception of it may become a part of possible experience. +But the science of mathematics has nothing to do with such +questions, nor with the question of existence in any fashion; it is +concerned merely with the properties of objects in themselves, only +in so far as these are connected with the conception of the objects. + +In the above example, we merely attempted to show the great +difference which exists between the discursive employment of reason +in the sphere of conceptions, and its intuitive exercise by means of +the construction of conceptions. The question naturally arises: What +is the cause which necessitates this twofold exercise of reason, and +how are we to discover whether it is the philosophical or the +mathematical method which reason is pursuing in an argument? + +All our knowledge relates, finally, to possible intuitions, for it +is these alone that present objects to the mind. An a priori or +non-empirical conception contains either a pure intuition--and in this +case it can be constructed; or it contains nothing but the synthesis +of possible intuitions, which are not given a priori. In this latter +case, it may help us to form synthetical a priori judgements, but only +in the discursive method, by conceptions, not in the intuitive, by +means of the construction of conceptions. + +The only a priori intuition is that of the pure form of phenomena- +space and time. A conception of space and time as quanta may be +presented a priori in intuition, that is, constructed, either alone +with their quality (figure), or as pure quantity (the mere synthesis +of the homogeneous), by means of number. But the matter of +phenomena, by which things are given in space and time, can be +presented only in perception, a posteriori. The only conception +which represents a priori this empirical content of phenomena is the +conception of a thing in general; and the a priori synthetical +cognition of this conception can give us nothing more than the rule +for the synthesis of that which may be contained in the +corresponding a posteriori perception; it is utterly inadequate to +present an a priori intuition of the real object, which must +necessarily be empirical. + +Synthetical propositions, which relate to things in general, an a +priori intuition of which is impossible, are transcendental. For +this reason transcendental propositions cannot be framed by means of +the construction of conceptions; they are a priori, and based entirely +on conceptions themselves. They contain merely the rule, by which we +are to seek in the world of perception or experience the synthetical +unity of that which cannot be intuited a priori. But they are +incompetent to present any of the conceptions which appear in them +in an a priori intuition; these can be given only a posteriori, in +experience, which, however, is itself possible only through these +synthetical principles. + +If we are to form a synthetical judgement regarding a conception, we +must go beyond it, to the intuition in which it is given. If we keep +to what is contained in the conception, the judgement is merely +analytical--it is merely an explanation of what we have cogitated in +the conception. But I can pass from the conception to the pure or +empirical intuition which corresponds to it. I can proceed to +examine my conception in concreto, and to cognize, either a priori +or a posterio, what I find in the object of the conception. The +former--a priori cognition--is rational-mathematical cognition by +means of the construction of the conception; the latter--a +posteriori cognition--is purely empirical cognition, which does not +possess the attributes of necessity and universality. Thus I may +analyse the conception I have of gold; but I gain no new information +from this analysis, I merely enumerate the different properties +which I had connected with the notion indicated by the word. My +knowledge has gained in logical clearness and arrangement, but no +addition has been made to it. But if I take the matter which is +indicated by this name, and submit it to the examination of my senses, +I am enabled to form several synthetical--although still empirical- +propositions. The mathematical conception of a triangle I should +construct, that is, present a priori in intuition, and in this way +attain to rational-synthetical cognition. But when the +transcendental conception of reality, or substance, or power is +presented to my mind, I find that it does not relate to or indicate +either an empirical or pure intuition, but that it indicates merely +the synthesis of empirical intuitions, which cannot of course be given +a priori. The synthesis in such a conception cannot proceed a +priori--without the aid of experience--to the intuition which +corresponds to the conception; and, for this reason, none of these +conceptions can produce a determinative synthetical proposition, +they can never present more than a principle of the synthesis* of +possible empirical intuitions. A transcendental proposition is, +therefore, a synthetical cognition of reason by means of pure +conceptions and the discursive method, and it renders possible all +synthetical unity in empirical cognition, though it cannot present +us with any intuition a priori. + + +[*Footnote: In the case of the conception of cause, I do really go +beyond the empirical conception of an event--but not to the intuition +which presents this conception in concreto, but only to the +time-conditions, which may be found in experience to correspond to +the conception. My procedure is, therefore, strictly according to +conceptions; I cannot in a case of this kind employ the construction +of conceptions, because the conception is merely a rule for the synthesis +of perceptions, which are not pure intuitions, and which, therefore, +cannot be given a priori.] + + +There is thus a twofold exercise of reason. Both modes have the +properties of universality and an a priori origin in common, but +are, in their procedure, of widely different character. The reason +of this is that in the world of phenomena, in which alone objects +are presented to our minds, there are two main elements--the form of +intuition (space and time), which can be cognized and determined +completely a priori, and the matter or content--that which is +presented in space and time, and which, consequently, contains a +something--an existence corresponding to our powers of sensation. As +regards the latter, which can never be given in a determinate mode +except by experience, there are no a priori notions which relate to +it, except the undetermined conceptions of the synthesis of possible +sensations, in so far as these belong (in a possible experience) to +the unity of consciousness. As regards the former, we can determine +our conceptions a priori in intuition, inasmuch as we are ourselves +the creators of the objects of the conceptions in space and time- +these objects being regarded simply as quanta. In the one case, reason +proceeds according to conceptions and can do nothing more than subject +phenomena to these--which can only be determined empirically, that +is, a posteriori--in conformity, however, with those conceptions as +the rules of all empirical synthesis. In the other case, reason proceeds +by the construction of conceptions; and, as these conceptions relate +to an a priori intuition, they may be given and determined in pure +intuition a priori, and without the aid of empirical data. The +examination and consideration of everything that exists in space or +time--whether it is a quantum or not, in how far the particular +something (which fills space or time) is a primary substratum, or a +mere determination of some other existence, whether it relates to +anything else--either as cause or effect, whether its existence is +isolated or in reciprocal connection with and dependence upon +others, the possibility of this existence, its reality and necessity +or opposites--all these form part of the cognition of reason on the +ground of conceptions, and this cognition is termed philosophical. +But to determine a priori an intuition in space (its figure), to divide +time into periods, or merely to cognize the quantity of an intuition +in space and time, and to determine it by number--all this is an +operation of reason by means of the construction of conceptions, and +is called mathematical. + +The success which attends the efforts of reason in the sphere of +mathematics naturally fosters the expectation that the same good +fortune will be its lot, if it applies the mathematical method in +other regions of mental endeavour besides that of quantities. Its +success is thus great, because it can support all its conceptions by +a priori intuitions and, in this way, make itself a master, as it +were, over nature; while pure philosophy, with its a priori discursive +conceptions, bungles about in the world of nature, and cannot accredit +or show any a priori evidence of the reality of these conceptions. +Masters in the science of mathematics are confident of the success +of this method; indeed, it is a common persuasion that it is capable +of being applied to any subject of human thought. They have hardly +ever reflected or philosophized on their favourite science--a task +of great difficulty; and the specific difference between the two modes +of employing the faculty of reason has never entered their thoughts. +Rules current in the field of common experience, and which common +sense stamps everywhere with its approval, are regarded by them as +axiomatic. From what source the conceptions of space and time, with +which (as the only primitive quanta) they have to deal, enter their +minds, is a question which they do not trouble themselves to answer; +and they think it just as unnecessary to examine into the origin of +the pure conceptions of the understanding and the extent of their +validity. All they have to do with them is to employ them. In all this +they are perfectly right, if they do not overstep the limits of the +sphere of nature. But they pass, unconsciously, from the world of +sense to the insecure ground of pure transcendental conceptions +(instabilis tellus, innabilis unda), where they can neither stand +nor swim, and where the tracks of their footsteps are obliterated by +time; while the march of mathematics is pursued on a broad and +magnificent highway, which the latest posterity shall frequent without +fear of danger or impediment. + +As we have taken upon us the task of determining, clearly and +certainly, the limits of pure reason in the sphere of +transcendentalism, and as the efforts of reason in this direction +are persisted in, even after the plainest and most expressive +warnings, hope still beckoning us past the limits of experience into +the splendours of the intellectual world--it becomes necessary to +cut away the last anchor of this fallacious and fantastic hope. We +shall, accordingly, show that the mathematical method is unattended +in the sphere of philosophy by the least advantage--except, perhaps, +that it more plainly exhibits its own inadequacy--that geometry and +philosophy are two quite different things, although they go band in +hand in hand in the field of natural science, and, consequently, +that the procedure of the one can never be imitated by the other. + +The evidence of mathematics rests upon definitions, axioms, and +demonstrations. I shall be satisfied with showing that none of these +forms can be employed or imitated in philosophy in the sense in +which they are understood by mathematicians; and that the +geometrician, if he employs his method in philosophy, will succeed +only in building card-castles, while the employment of the +philosophical method in mathematics can result in nothing but mere +verbiage. The essential business of philosophy, indeed, is to mark +out the limits of the science; and even the mathematician, unless his +talent is naturally circumscribed and limited to this particular +department of knowledge, cannot turn a deaf ear to the warnings of +philosophy, or set himself above its direction. + +I. Of Definitions. A definition is, as the term itself indicates, +the representation, upon primary grounds, of the complete conception +of a thing within its own limits.* Accordingly, an empirical +conception cannot be defined, it can only be explained. For, as +there are in such a conception only a certain number of marks or +signs, which denote a certain class of sensuous objects, we can +never be sure that we do not cogitate under the word which indicates +the same object, at one time a greater, at another a smaller number +of signs. Thus, one person may cogitate in his conception of gold, +in addition to its properties of weight, colour, malleability, that +of resisting rust, while another person may be ignorant of this +quality. We employ certain signs only so long as we require them for +the sake of distinction; new observations abstract some and add new +ones, so that an empirical conception never remains within permanent +limits. It is, in fact, useless to define a conception of this kind. +If, for example, we are speaking of water and its properties, we do +not stop at what we actually think by the word water, but proceed to +observation and experiment; and the word, with the few signs +attached to it, is more properly a designation than a conception of +the thing. A definition in this case would evidently be nothing more +than a determination of the word. In the second place, no a priori +conception, such as those of substance, cause, right, fitness, and +so on, can be defined. For I can never be sure, that the clear +representation of a given conception (which is given in a confused +state) has been fully developed, until I know that the +representation is adequate with its object. But, inasmuch as the +conception, as it is presented to the mind, may contain a number of +obscure representations, which we do not observe in our analysis, +although we employ them in our application of the conception, I can +never be sure that my analysis is complete, while examples may make +this probable, although they can never demonstrate the fact. Instead +of the word definition, I should rather employ the term exposition-- +a more modest expression, which the critic may accept without +surrendering his doubts as to the completeness of the analysis of +any such conception. As, therefore, neither empirical nor a priori +conceptions are capable of definition, we have to see whether the only +other kind of conceptions--arbitrary conceptions--can be subjected +to this mental operation. Such a conception can always be defined; +for I must know thoroughly what I wished to cogitate in it, as it was +I who created it, and it was not given to my mind either by the nature +of my understanding or by experience. At the same time, I cannot say +that, by such a definition, I have defined a real object. If the +conception is based upon empirical conditions, if, for example, I have +a conception of a clock for a ship, this arbitrary conception does +not assure me of the existence or even of the possibility of the object. +My definition of such a conception would with more propriety be termed +a declaration of a project than a definition of an object. There +are no other conceptions which can bear definition, except those which +contain an arbitrary synthesis, which can be constructed a priori. +Consequently, the science of mathematics alone possesses +definitions. For the object here thought is presented a priori in +intuition; and thus it can never contain more or less than the +conception, because the conception of the object has been given by +the definition--and primarily, that is, without deriving the definition +from any other source. Philosophical definitions are, therefore, +merely expositions of given conceptions, while mathematical +definitions are constructions of conceptions originally formed by +the mind itself; the former are produced by analysis, the completeness +of which is never demonstratively certain, the latter by a +synthesis. In a mathematical definition the conception is formed, in +a philosophical definition it is only explained. From this it follows: + +[*Footnote: The definition must describe the conception completely +that is, omit none of the marks or signs of which it composed; within +its own limits, that is, it must be precise, and enumerate no more +signs than belong to the conception; and on primary grounds, that is +to say, the limitations of the bounds of the conception must not be +deduced from other conceptions, as in this case a proof would be necessary, +and the so-called definition would be incapable of taking its place +at the bead of all the judgements we have to form regarding an object.] + +(a) That we must not imitate, in philosophy, the mathematical +usage of commencing with definitions--except by way of hypothesis or +experiment. For, as all so-called philosophical definitions are merely +analyses of given conceptions, these conceptions, although only in +a confused form, must precede the analysis; and the incomplete +exposition must precede the complete, so that we may be able to draw +certain inferences from the characteristics which an incomplete +analysis has enabled us to discover, before we attain to the +complete exposition or definition of the conception. In one word, a +full and clear definition ought, in philosophy, rather to form the +conclusion than the commencement of our labours.* In mathematics, on +the contrary, we cannot have a conception prior to the definition; +it is the definition which gives us the conception, and it must for +this reason form the commencement of every chain of mathematical +reasoning. + +[*Footnote: Philosophy abounds in faulty definitions, especially such +as contain some of the elements requisite to form a complete +definition. If a conception could not be employed in reasoning +before it had been defined, it would fare ill with all philosophical +thought. But, as incompletely defined conceptions may always be +employed without detriment to truth, so far as our analysis of the +elements contained in them proceeds, imperfect definitions, that is, +propositions which are properly not definitions, but merely +approximations thereto, may be used with great advantage. In +mathematics, definition belongs ad esse, in philosophy ad melius esse. +It is a difficult task to construct a proper definition. Jurists are +still without a complete definition of the idea of right.] + +(b) Mathematical definitions cannot be erroneous. For the conception +is given only in and through the definition, and thus it contains only +what has been cogitated in the definition. But although a definition +cannot be incorrect, as regards its content, an error may sometimes, +although seldom, creep into the form. This error consists in a want +of precision. Thus the common definition of a circle--that it is a +curved line, every point in which is equally distant from another point +called the centre--is faulty, from the fact that the determination +indicated by the word curved is superfluous. For there ought to be +a particular theorem, which may be easily proved from the definition, +to the effect that every line, which has all its points at equal +distances from another point, must be a curved line--that is, that +not even the smallest part of it can be straight. Analytical +definitions, on the other hand, may be erroneous in many respects, +either by the introduction of signs which do not actually exist in +the conception, or by wanting in that completeness which forms the +essential of a definition. In the latter case, the definition is +necessarily defective, because we can never be fully certain of the +completeness of our analysis. For these reasons, the method of +definition employed in mathematics cannot be imitated in philosophy. + +2. Of Axioms. These, in so far as they are immediately certain, +are a priori synthetical principles. Now, one conception cannot be +connected synthetically and yet immediately with another; because, +if we wish to proceed out of and beyond a conception, a third +mediating cognition is necessary. And, as philosophy is a cognition +of reason by the aid of conceptions alone, there is to be found in +it no principle which deserves to be called an axiom. Mathematics, +on the other hand, may possess axioms, because it can always connect +the predicates of an object a priori, and without any mediating term, +by means of the construction of conceptions in intuition. Such is the +case with the proposition: Three points can always lie in a plane. +On the other hand, no synthetical principle which is based upon +conceptions, can ever be immediately certain (for example, the +proposition: Everything that happens has a cause), because I require +a mediating term to connect the two conceptions of event and cause- +namely, the condition of time-determination in an experience, and I +cannot cognize any such principle immediately and from conceptions +alone. Discursive principles are, accordingly, very different from +intuitive principles or axioms. The former always require deduction, +which in the case of the latter may be altogether dispensed with. +Axioms are, for this reason, always self-evident, while +philosophical principles, whatever may be the degree of certainty they +possess, cannot lay any claim to such a distinction. No synthetical +proposition of pure transcendental reason can be so evident, as is +often rashly enough declared, as the statement, twice two are four. +It is true that in the Analytic I introduced into the list of +principles of the pure understanding, certain axioms of intuition; +but the principle there discussed was not itself an axiom, but served +merely to present the principle of the possibility of axioms in +general, while it was really nothing more than a principle based +upon conceptions. For it is one part of the duty of transcendental +philosophy to establish the possibility of mathematics itself. +Philosophy possesses, then, no axioms, and has no right to impose +its a priori principles upon thought, until it has established their +authority and validity by a thoroughgoing deduction. + +3. Of Demonstrations. Only an apodeictic proof, based upon +intuition, can be termed a demonstration. Experience teaches us what +is, but it cannot convince us that it might not have been otherwise. +Hence a proof upon empirical grounds cannot be apodeictic. A priori +conceptions, in discursive cognition, can never produce intuitive +certainty or evidence, however certain the judgement they present +may be. Mathematics alone, therefore, contains demonstrations, because +it does not deduce its cognition from conceptions, but from the +construction of conceptions, that is, from intuition, which can be +given a priori in accordance with conceptions. The method of +algebra, in equations, from which the correct answer is deduced by +reduction, is a kind of construction--not geometrical, but by symbols- +in which all conceptions, especially those of the relations of +quantities, are represented in intuition by signs; and thus the +conclusions in that science are secured from errors by the fact that +every proof is submitted to ocular evidence. Philosophical cognition +does not possess this advantage, it being required to consider the +general always in abstracto (by means of conceptions), while +mathematics can always consider it in concreto (in an individual +intuition), and at the same time by means of a priori +representation, whereby all errors are rendered manifest to the +senses. The former--discursive proofs--ought to be termed acroamatic +proofs, rather than demonstrations, as only words are employed in +them, while demonstrations proper, as the term itself indicates, +always require a reference to the intuition of the object. + +It follows from all these considerations that it is not consonant +with the nature of philosophy, especially in the sphere of pure +reason, to employ the dogmatical method, and to adorn itself with +the titles and insignia of mathematical science. It does not belong +to that order, and can only hope for a fraternal union with that science. +Its attempts at mathematical evidence are vain pretensions, which +can only keep it back from its true aim, which is to detect the +illusory procedure of reason when transgressing its proper limits, +and by fully explaining and analysing our conceptions, to conduct us +from the dim regions of speculation to the clear region of modest +self-knowledge. Reason must not, therefore, in its transcendental +endeavours, look forward with such confidence, as if the path it is +pursuing led straight to its aim, nor reckon with such security upon +its premisses, as to consider it unnecessary to take a step back, or +to keep a strict watch for errors, which, overlooked in the +principles, may be detected in the arguments themselves--in which case +it may be requisite either to determine these principles with +greater strictness, or to change them entirely. + +I divide all apodeictic propositions, whether demonstrable or +immediately certain, into dogmata and mathemata. A direct +synthetical proposition, based on conceptions, is a dogma; a +proposition of the same kind, based on the construction of +conceptions, is a mathema. Analytical judgements do not teach us any +more about an object than what was contained in the conception we +had of it; because they do not extend our cognition beyond our +conception of an object, they merely elucidate the conception. They +cannot therefore be with propriety termed dogmas. Of the two kinds +of a priori synthetical propositions above mentioned, only those which +are employed in philosophy can, according to the general mode of +speech, bear this name; those of arithmetic or geometry would not be +rightly so denominated. Thus the customary mode of speaking confirms +the explanation given above, and the conclusion arrived at, that +only those judgements which are based upon conceptions, not on the +construction of conceptions, can be termed dogmatical. + +Thus, pure reason, in the sphere of speculation, does not contain +a single direct synthetical judgement based upon conceptions. By means +of ideas, it is, as we have shown, incapable of producing +synthetical judgements, which are objectively valid; by means of the +conceptions of the understanding, it establishes certain indubitable +principles, not, however, directly on the basis of conceptions, but +only indirectly by means of the relation of these conceptions to +something of a purely contingent nature, namely, possible +experience. When experience is presupposed, these principles are +apodeictically certain, but in themselves, and directly, they cannot +even be cognized a priori. Thus the given conceptions of cause and +event will not be sufficient for the demonstration of the proposition: +Every event has a cause. For this reason, it is not a dogma; +although from another point of view, that of experience, it is capable +of being proved to demonstration. The proper term for such a +proposition is principle, and not theorem (although it does require +to be proved), because it possesses the remarkable peculiarity of being +the condition of the possibility of its own ground of proof, that +is, experience, and of forming a necessary presupposition in all +empirical observation. + +If then, in the speculative sphere of pure reason, no dogmata are to +be found; all dogmatical methods, whether borrowed from mathematics, +or invented by philosophical thinkers, are alike inappropriate and +inefficient. They only serve to conceal errors and fallacies, and to +deceive philosophy, whose duty it is to see that reason pursues a safe +and straight path. A philosophical method may, however, be +systematical. For our reason is, subjectively considered, itself a +system, and, in the sphere of mere conceptions, a system of +investigation according to principles of unity, the material being +supplied by experience alone. But this is not the proper place for +discussing the peculiar method of transcendental philosophy, as our +present task is simply to examine whether our faculties are capable +of erecting an edifice on the basis of pure reason, and how far they +may proceed with the materials at their command. + + + +SECTION II. The Discipline of Pure Reason in Polemics. + +Reason must be subject, in all its operations, to criticism, which +must always be permitted to exercise its functions without +restraint; otherwise its interests are imperilled and its influence +obnoxious to suspicion. There is nothing, however useful, however +sacred it may be, that can claim exemption from the searching +examination of this supreme tribunal, which has no respect of persons. +The very existence of reason depends upon this freedom; for the +voice of reason is not that of a dictatorial and despotic power, it +is rather like the vote of the citizens of a free state, every member +of which must have the privilege of giving free expression to his +doubts, and possess even the right of veto. + +But while reason can never decline to submit itself to the +tribunal of criticism, it has not always cause to dread the +judgement of this court. Pure reason, however, when engaged in the +sphere of dogmatism, is not so thoroughly conscious of a strict +observance of its highest laws, as to appear before a higher +judicial reason with perfect confidence. On the contrary, it must +renounce its magnificent dogmatical pretensions in philosophy. + +Very different is the case when it has to defend itself, not +before a judge, but against an equal. If dogmatical assertions are +advanced on the negative side, in opposition to those made by reason +on the positive side, its justification kat authrhopon is complete, +although the proof of its propositions is kat aletheian +unsatisfactory. + +By the polemic of pure reason I mean the defence of its propositions +made by reason, in opposition to the dogmatical counter-propositions +advanced by other parties. The question here is not whether its own +statements may not also be false; it merely regards the fact that +reason proves that the opposite cannot be established with +demonstrative certainty, nor even asserted with a higher degree of +probability. Reason does not hold her possessions upon sufferance; +for, although she cannot show a perfectly satisfactory title to +them, no one can prove that she is not the rightful possessor. + +It is a melancholy reflection that reason, in its highest +exercise, falls into an antithetic; and that the supreme tribunal +for the settlement of differences should not be at union with +itself. It is true that we had to discuss the question of an +apparent antithetic, but we found that it was based upon a +misconception. In conformity with the common prejudice, phenomena were +regarded as things in themselves, and thus an absolute completeness +in their synthesis was required in the one mode or in the other (it +was shown to be impossible in both); a demand entirely out of place +in regard to phenomena. There was, then, no real self-contradiction +of reason in the propositions: The series of phenomena given in +themselves has an absolutely first beginning; and: This series is +absolutely and in itself without beginning. The two propositions are +perfectly consistent with each other, because phenomena as phenomena +are in themselves nothing, and consequently the hypothesis that they +are things in themselves must lead to self-contradictory inferences. + +But there are cases in which a similar misunderstanding cannot be +provided against, and the dispute must remain unsettled. Take, for +example, the theistic proposition: There is a Supreme Being; and on +the other hand, the atheistic counter-statement: There exists no +Supreme Being; or, in psychology: Everything that thinks possesses +the attribute of absolute and permanent unity, which is utterly +different from the transitory unity of material phenomena; and the +counter-proposition: The soul is not an immaterial unity, and its +nature is transitory, like that of phenomena. The objects of these +questions contain no heterogeneous or contradictory elements, for they +relate to things in themselves, and not to phenomena. There would +arise, indeed, a real contradiction, if reason came forward with a +statement on the negative side of these questions alone. As regards +the criticism to which the grounds of proof on the affirmative side +must be subjected, it may be freely admitted, without necessitating +the surrender of the affirmative propositions, which have, at least, +the interest of reason in their favour--an advantage which the +opposite party cannot lay claim to. + +I cannot agree with the opinion of several admirable thinkers--Sulzer +among the rest--that, in spite of the weakness of the arguments +hitherto in use, we may hope, one day, to see sufficient demonstrations +of the two cardinal propositions of pure reason--the existence of a +Supreme Being, and the immortality of the soul. I am certain, on the +contrary, that this will never be the case. For on what ground can +reason base such synthetical propositions, which do not relate to the +objects of experience and their internal possibility? But it is also +demonstratively certain that no one will ever be able to maintain the +contrary with the least show of probability. For, as he can attempt +such a proof solely upon the basis of pure reason, he is bound to prove +that a Supreme Being, and a thinking subject in the character of a pure +intelligence, are impossible. But where will he find the knowledge +which can enable him to enounce synthetical judgements in regard to +things which transcend the region of experience? We may, therefore, +rest assured that the opposite never will be demonstrated. We need not, +then, have recourse to scholastic arguments; we may always admit the +truth of those propositions which are consistent with the speculative +interests of reason in the sphere of experience, and form, moreover, +the only means of uniting the speculative with the practical interest. +Our opponent, who must not be considered here as a critic solely, we +can be ready to meet with a non liquet which cannot fail to disconcert +him; while we cannot deny his right to a similar retort, as we have on +our side the advantage of the support of the subjective maxim of +reason, and can therefore look upon all his sophistical arguments with +calm indifference. + +From this point of view, there is properly no antithetic of pure +reason. For the only arena for such a struggle would be upon the field +of pure theology and psychology; but on this ground there can appear +no combatant whom we need to fear. Ridicule and boasting can be his +only weapons; and these may be laughed at, as mere child's play. +This consideration restores to Reason her courage; for what source +of confidence could be found, if she, whose vocation it is to +destroy error, were at variance with herself and without any +reasonable hope of ever reaching a state of permanent repose? + +Everything in nature is good for some purpose. Even poisons are +serviceable; they destroy the evil effects of other poisons generated +in our system, and must always find a place in every complete +pharmacopoeia. The objections raised against the fallacies and +sophistries of speculative reason, are objections given by the nature +of this reason itself, and must therefore have a destination and +purpose which can only be for the good of humanity. For what purpose +has Providence raised many objects, in which we have the deepest +interest, so far above us, that we vainly try to cognize them with +certainty, and our powers of mental vision are rather excited than +satisfied by the glimpses we may chance to seize? It is very doubtful +whether it is for our benefit to advance bold affirmations regarding +subjects involved in such obscurity; perhaps it would even be +detrimental to our best interests. But it is undoubtedly always +beneficial to leave the investigating, as well as the critical reason, +in perfect freedom, and permit it to take charge of its own interests, +which are advanced as much by its limitation, as by its extension of +its views, and which always suffer by the interference of foreign +powers forcing it, against its natural tendencies, to bend to certain +preconceived designs. + +Allow your opponent to say what he thinks reasonable, and combat him +only with the weapons of reason. Have no anxiety for the practical +interests of humanity--these are never imperilled in a purely +speculative dispute. Such a dispute serves merely to disclose the +antinomy of reason, which, as it has its source in the nature of +reason, ought to be thoroughly investigated. Reason is benefited by +the examination of a subject on both sides, and its judgements are +corrected by being limited. It is not the matter that may give +occasion to dispute, but the manner. For it is perfectly permissible +to employ, in the presence of reason, the language of a firmly +rooted faith, even after we have been obliged to renounce all +pretensions to knowledge. + +If we were to ask the dispassionate David Hume--a philosopher +endowed, in a degree that few are, with a well-balanced judgement: +What motive induced you to spend so much labour and thought in +undermining the consoling and beneficial persuasion that reason is +capable of assuring us of the existence, and presenting us with a +determinate conception of a Supreme Being?--his answer would be: +Nothing but the desire of teaching reason to know its own powers +better, and, at the same time, a dislike of the procedure by which +that faculty was compelled to support foregone conclusions, and +prevented from confessing the internal weaknesses which it cannot +but feel when it enters upon a rigid self-examination. If, on the +other hand, we were to ask Priestley--a philosopher who had no taste +for transcendental speculation, but was entirely devoted to the +principles of empiricism--what his motives were for overturning +those two main pillars of religion--the doctrines of the freedom of +the will and the immortality of the soul (in his view the hope of a +future life is but the expectation of the miracle of resurrection)- +this philosopher, himself a zealous and pious teacher of religion, +could give no other answer than this: I acted in the interest of +reason, which always suffers, when certain objects are explained and +judged by a reference to other supposed laws than those of material +nature--the only laws which we know in a determinate manner. It +would be unfair to decry the latter philosopher, who endeavoured to +harmonize his paradoxical opinions with the interests of religion, +and to undervalue an honest and reflecting man, because he finds himself +at a loss the moment he has left the field of natural science. The +same grace must be accorded to Hume, a man not less well-disposed, +and quite as blameless in his moral character, and who pushed his abstract +speculations to an extreme length, because, as he rightly believed, +the object of them lies entirely beyond the bounds of natural science, +and within the sphere of pure ideas. + +What is to be done to provide against the danger which seems in +the present case to menace the best interests of humanity? The +course to be pursued in reference to this subject is a perfectly plain +and natural one. Let each thinker pursue his own path; if he shows +talent, if he gives evidence of profound thought, in one word, if he +shows that he possesses the power of reasoning--reason is always the +gainer. If you have recourse to other means, if you attempt to +coerce reason, if you raise the cry of treason to humanity, if you +excite the feelings of the crowd, which can neither understand nor +sympathize with such subtle speculations--you will only make +yourselves ridiculous. For the question does not concern the advantage +or disadvantage which we are expected to reap from such inquiries; +the question is merely how far reason can advance in the field of +speculation, apart from all kinds of interest, and whether we may +depend upon the exertions of speculative reason, or must renounce +all reliance on it. Instead of joining the combatants, it is your part +to be a tranquil spectator of the struggle--a laborious struggle for +the parties engaged, but attended, in its progress as well as in its +result, with the most advantageous consequences for the interests of +thought and knowledge. It is absurd to expect to be enlightened by +Reason, and at the same time to prescribe to her what side of the +question she must adopt. Moreover, reason is sufficiently held in +check by its own power, the limits imposed on it by its own nature +are sufficient; it is unnecessary for you to place over it additional +guards, as if its power were dangerous to the constitution of the +intellectual state. In the dialectic of reason there is no victory +gained which need in the least disturb your tranquility. + +The strife of dialectic is a necessity of reason, and we cannot +but wish that it had been conducted long ere this with that perfect +freedom which ought to be its essential condition. In this case, we +should have had at an earlier period a matured and profound criticism, +which must have put an end to all dialectical disputes, by exposing +the illusions and prejudices in which they originated. + +There is in human nature an unworthy propensity--a propensity which, +like everything that springs from nature, must in its final purpose +be conducive to the good of humanity--to conceal our real sentiments, +and to give expression only to certain received opinions, which are +regarded as at once safe and promotive of the common good. It is true, +this tendency, not only to conceal our real sentiments, but to profess +those which may gain us favour in the eyes of society, has not only +civilized, but, in a certain measure, moralized us; as no one can +break through the outward covering of respectability, honour, and +morality, and thus the seemingly-good examples which we which we see +around us form an excellent school for moral improvement, so long as +our belief in their genuineness remains unshaken. But this disposition +to represent ourselves as better than we are, and to utter opinions +which are not our own, can be nothing more than a kind of provisionary +arrangement of nature to lead us from the rudeness of an uncivilized +state, and to teach us how to assume at least the appearance and +manner of the good we see. But when true principles have been +developed, and have obtained a sure foundation in our habit of +thought, this conventionalism must be attacked with earnest vigour, +otherwise it corrupts the heart, and checks the growth of good +dispositions with the mischievous weed of air appearances. + +I am sorry to remark the same tendency to misrepresentation and +hypocrisy in the sphere of speculative discussion, where there is less +temptation to restrain the free expression of thought. For what can +be more prejudicial to the interests of intelligence than to falsify +our real sentiments, to conceal the doubts which we feel in regard +to our statements, or to maintain the validity of grounds of proof +which we well know to be insufficient? So long as mere personal vanity +is the source of these unworthy artifices--and this is generally the +case in speculative discussions, which are mostly destitute of +practical interest, and are incapable of complete demonstration--the +vanity of the opposite party exaggerates as much on the other side; +and thus the result is the same, although it is not brought about so +soon as if the dispute had been conducted in a sincere and upright +spirit. But where the mass entertains the notion that the aim of +certain subtle speculators is nothing less than to shake the very +foundations of public welfare and morality--it seems not only prudent, +but even praise worthy, to maintain the good cause by illusory +arguments, rather than to give to our supposed opponents the advantage +of lowering our declarations to the moderate tone of a merely +practical conviction, and of compelling us to confess our inability +to attain to apodeictic certainty in speculative subjects. But we ought +to reflect that there is nothing, in the world more fatal to the +maintenance of a good cause than deceit, misrepresentation, and +falsehood. That the strictest laws of honesty should be observed in +the discussion of a purely speculative subject is the least +requirement that can be made. If we could reckon with security even +upon so little, the conflict of speculative reason regarding the +important questions of God, immortality, and freedom, would have +been either decided long ago, or would very soon be brought to a +conclusion. But, in general, the uprightness of the defence stands +in an inverse ratio to the goodness of the cause; and perhaps more +honesty and fairness are shown by those who deny than by those who +uphold these doctrines. + +I shall persuade myself, then, that I have readers who do not wish +to see a righteous cause defended by unfair arguments. Such will now +recognize the fact that, according to the principles of this Critique, +if we consider not what is, but what ought to be the case, there can +be really no polemic of pure reason. For how can two persons dispute +about a thing, the reality of which neither can present in actual or +even in possible experience? Each adopts the plan of meditating on +his idea for the purpose of drawing from the idea, if he can, what +is more than the idea, that is, the reality of the object which it +indicates. How shall they settle the dispute, since neither is able +to make his assertions directly comprehensible and certain, but must +restrict himself to attacking and confuting those of his opponent? +All statements enounced by pure reason transcend the conditions of +possible experience, beyond the sphere of which we can discover no +criterion of truth, while they are at the same time framed in +accordance with the laws of the understanding, which are applicable +only to experience; and thus it is the fate of all such speculative +discussions that while the one party attacks the weaker side of his +opponent, he infallibly lays open his own weaknesses. + +The critique of pure reason may be regarded as the highest +tribunal for all speculative disputes; for it is not involved in these +disputes, which have an immediate relation to certain objects and +not to the laws of the mind, but is instituted for the purpose of +determining the rights and limits of reason. + +Without the control of criticism, reason is, as it were, in a +state of nature, and can only establish its claims and assertions by +war. Criticism, on the contrary, deciding all questions according to +the fundamental laws of its own institution, secures to us the peace +of law and order, and enables us to discuss all differences in the +more tranquil manner of a legal process. In the former case, +disputes are ended by victory, which both sides may claim and which +is followed by a hollow armistice; in the latter, by a sentence, which, +as it strikes at the root of all speculative differences, ensures to +all concerned a lasting peace. The endless disputes of a dogmatizing +reason compel us to look for some mode of arriving at a settled +decision by a critical investigation of reason itself; just as +Hobbes maintains that the state of nature is a state of injustice +and violence, and that we must leave it and submit ourselves to the +constraint of law, which indeed limits individual freedom, but only +that it may consist with the freedom of others and with the common +good of all. + +This freedom will, among other things, permit of our openly +stating the difficulties and doubts which we are ourselves unable to +solve, without being decried on that account as turbulent and +dangerous citizens. This privilege forms part of the native rights +of human reason, which recognizes no other judge than the universal +reason of humanity; and as this reason is the source of all progress +and improvement, such a privilege is to be held sacred and inviolable. +It is unwise, moreover, to denounce as dangerous any bold assertions +against, or rash attacks upon, an opinion which is held by the largest +and most moral class of the community; for that would be giving them +an importance which they do not deserve. When I hear that the +freedom of the will, the hope of a future life, and the existence of +God have been overthrown by the arguments of some able writer, I +feel a strong desire to read his book; for I expect that he will add +to my knowledge and impart greater clearness and distinctness to my +views by the argumentative power shown in his writings. But I am +perfectly certain, even before I have opened the book, that he has +not succeeded in a single point, not because I believe I am in +possession of irrefutable demonstrations of these important +propositions, but because this transcendental critique, which has +disclosed to me the power and the limits of pure reason, has fully +convinced me that, as it is insufficient to establish the affirmative, +it is as powerless, and even more so, to assure us of the truth of +the negative answer to these questions. From what source does this +free-thinker derive his knowledge that there is, for example, no +Supreme Being? This proposition lies out of the field of possible +experience, and, therefore, beyond the limits of human cognition. +But I would not read at, all the answer which the dogmatical +maintainer of the good cause makes to his opponent, because I know +well beforehand, that he will merely attack the fallacious grounds +of his adversary, without being able to establish his own +assertions. Besides, a new illusory argument, in the construction of +which talent and acuteness are shown, is suggestive of new ideas and +new trains of reasoning, and in this respect the old and everyday +sophistries are quite useless. Again, the dogmatical opponent of +religion gives employment to criticism, and enables us to test and +correct its principles, while there is no occasion for anxiety in +regard to the influence and results of his reasoning. + +But, it will be said, must we not warn the youth entrusted to +academical care against such writings, must we not preserve them +from the knowledge of these dangerous assertions, until their +judgement is ripened, or rather until the doctrines which we wish to +inculcate are so firmly rooted in their minds as to withstand all +attempts at instilling the contrary dogmas, from whatever quarter they +may come? + +If we are to confine ourselves to the dogmatical procedure in the +sphere of pure reason, and find ourselves unable to settle such +disputes otherwise than by becoming a party in them, and setting +counter-assertions against the statements advanced by our opponents, +there is certainly no plan more advisable for the moment, but, at +the same time, none more absurd and inefficient for the future, than +this retaining of the youthful mind under guardianship for a time, +and thus preserving it--for so long at least--from seduction into error. +But when, at a later period, either curiosity, or the prevalent +fashion of thought places such writings in their hands, will the +so-called convictions of their youth stand firm? The young thinker, +who has in his armoury none but dogmatical weapons with which to +resist the attacks of his opponent, and who cannot detect the latent +dialectic which lies in his own opinions as well as in those of the +opposite party, sees the advance of illusory arguments and grounds +of proof which have the advantage of novelty, against as illusory +grounds of proof destitute of this advantage, and which, perhaps, +excite the suspicion that the natural credulity of his youth has +been abused by his instructors. He thinks he can find no better +means of showing that he has out grown the discipline of his +minority than by despising those well-meant warnings, and, knowing +no system of thought but that of dogmatism, he drinks deep draughts +of the poison that is to sap the principles in which his early years +were trained. + +Exactly the opposite of the system here recommended ought to be +pursued in academical instruction. This can only be effected, however, +by a thorough training in the critical investigation of pure reason. +For, in order to bring the principles of this critique into exercise +as soon as possible, and to demonstrate their perfect even in the +presence of the highest degree of dialectical illusion, the student +ought to examine the assertions made on both sides of speculative +questions step by step, and to test them by these principles. It +cannot be a difficult task for him to show the fallacies inherent in +these propositions, and thus he begins early to feel his own power +of securing himself against the influence of such sophistical +arguments, which must finally lose, for him, all their illusory power. +And, although the same blows which overturn the edifice of his +opponent are as fatal to his own speculative structures, if such he +has wished to rear; he need not feel any sorrow in regard to this +seeming misfortune, as he has now before him a fair prospect into +the practical region in which he may reasonably hope to find a more +secure foundation for a rational system. + +There is, accordingly, no proper polemic in the sphere of pure +reason. Both parties beat the air and fight with their own shadows, +as they pass beyond the limits of nature, and can find no tangible +point of attack--no firm footing for their dogmatical conflict. +Fight as vigorously as they may, the shadows which they hew down, +immediately start up again, like the heroes in Walhalla, and renew +the bloodless and unceasing contest. + +But neither can we admit that there is any proper sceptical +employment of pure reason, such as might be based upon the principle +of neutrality in all speculative disputes. To excite reason against +itself, to place weapons in the hands of the party on the one side +as well as in those of the other, and to remain an undisturbed and +sarcastic spectator of the fierce struggle that ensues, seems, from +the dogmatical point of view, to be a part fitting only a malevolent +disposition. But, when the sophist evidences an invincible obstinacy +and blindness, and a pride which no criticism can moderate, there is +no other practicable course than to oppose to this pride and obstinacy +similar feelings and pretensions on the other side, equally well or +ill founded, so that reason, staggered by the reflections thus +forced upon it, finds it necessary to moderate its confidence in +such pretensions and to listen to the advice of criticism. But we +cannot stop at these doubts, much less regard the conviction of our +ignorance, not only as a cure for the conceit natural to dogmatism, +but as the settlement of the disputes in which reason is involved with +itself. On the contrary, scepticism is merely a means of awakening +reason from its dogmatic dreams and exciting it to a more careful +investigation into its own powers and pretensions. But, as +scepticism appears to be the shortest road to a permanent peace in +the domain of philosophy, and as it is the track pursued by the many +who aim at giving a philosophical colouring to their contemptuous +dislike of all inquiries of this kind, I think it necessary to present +to my readers this mode of thought in its true light. + + + +Scepticism not a Permanent State for Human Reason. + +The consciousness of ignorance--unless this ignorance is +recognized to be absolutely necessary ought, instead of forming the +conclusion of my inquiries, to be the strongest motive to the +pursuit of them. All ignorance is either ignorance of things or of +the limits of knowledge. If my ignorance is accidental and not +necessary, it must incite me, in the first case, to a dogmatical +inquiry regarding the objects of which I am ignorant; in the second, +to a critical investigation into the bounds of all possible knowledge. +But that my ignorance is absolutely necessary and unavoidable, and +that it consequently absolves from the duty of all further +investigation, is a fact which cannot be made out upon empirical +grounds--from observation--but upon critical grounds alone, that is, +by a thoroughgoing investigation into the primary sources of +cognition. It follows that the determination of the bounds of reason +can be made only on a priori grounds; while the empirical limitation +of reason, which is merely an indeterminate cognition of an +ignorance that can never be completely removed, can take place only +a posteriori. In other words, our empirical knowledge is limited by +that which yet remains for us to know. The former cognition of our +ignorance, which is possible only on a rational basis, is a science; +the latter is merely a perception, and we cannot say how far the +inferences drawn from it may extend. If I regard the earth, as it +really appears to my senses, as a flat surface, I am ignorant how +far this surface extends. But experience teaches me that, how far +soever I go, I always see before me a space in which I can proceed +farther; and thus I know the limits--merely visual--of my actual +knowledge of the earth, although I am ignorant of the limits of the +earth itself. But if I have got so far as to know that the earth is +a sphere, and that its surface is spherical, I can cognize a priori +and determine upon principles, from my knowledge of a small part of +this surface--say to the extent of a degree--the diameter and +circumference of the earth; and although I am ignorant of the +objects which this surface contains, I have a perfect knowledge of +its limits and extent. + +The sum of all the possible objects of our cognition seems to us +to be a level surface, with an apparent horizon--that which forms +the limit of its extent, and which has been termed by us the idea of +unconditioned totality. To reach this limit by empirical means is +impossible, and all attempts to determine it a priori according to +a principle, are alike in vain. But all the questions raised by pure +reason relate to that which lies beyond this horizon, or, at least, +in its boundary line. + +The celebrated David Hume was one of those geographers of human +reason who believe that they have given a sufficient answer to all +such questions by declaring them to lie beyond the horizon of our +knowledge--a horizon which, however, Hume was unable to determine. +His attention especially was directed to the principle of causality; +and he remarked with perfect justice that the truth of this principle, +and even the objective validity of the conception of a cause, was not +commonly based upon clear insight, that is, upon a priori cognition. +Hence he concluded that this law does not derive its authority from +its universality and necessity, but merely from its general +applicability in the course of experience, and a kind of subjective +necessity thence arising, which he termed habit. From the inability +of reason to establish this principle as a necessary law for the +acquisition of all experience, he inferred the nullity of all the +attempts of reason to pass the region of the empirical. + +This procedure of subjecting the facta of reason to examination, +and, if necessary, to disapproval, may be termed the censura of +reason. This censura must inevitably lead us to doubts regarding all +transcendent employment of principles. But this is only the second +step in our inquiry. The first step in regard to the subjects of +pure reason, and which marks the infancy of that faculty, is that of +dogmatism. The second, which we have just mentioned, is that of +scepticism, and it gives evidence that our judgement has been improved +by experience. But a third step is necessary--indicative of the +maturity and manhood of the judgement, which now lays a firm +foundation upon universal and necessary principles. This is the period +of criticism, in which we do not examine the facta of reason, but +reason itself, in the whole extent of its powers, and in regard to +its capability of a priori cognition; and thus we determine not merely +the empirical and ever-shifting bounds of our knowledge, but its necessary +and eternal limits. We demonstrate from indubitable principles, not +merely our ignorance in respect to this or that subject, but in regard +to all possible questions of a certain class. Thus scepticism is a +resting place for reason, in which it may reflect on its dogmatical +wanderings and gain some knowledge of the region in which it happens +to be, that it may pursue its way with greater certainty; but it +cannot be its permanent dwelling-place. It must take up its abode only +in the region of complete certitude, whether this relates to the +cognition of objects themselves, or to the limits which bound all +our cognition. + +Reason is not to be considered as an indefinitely extended plane, of +the bounds of which we have only a general knowledge; it ought +rather to be compared to a sphere, the radius of which may be found +from the curvature of its surface--that is, the nature of a priori +synthetical propositions--and, consequently, its circumference and +extent. Beyond the sphere of experience there are no objects which +it can cognize; nay, even questions regarding such supposititious +objects relate only to the subjective principles of a complete +determination of the relations which exist between the +understanding-conceptions which lie within this sphere. + +We are actually in possession of a priori synthetical cognitions, as +is proved by the existence of the principles of the understanding, +which anticipate experience. If any one cannot comprehend the +possibility of these principles, he may have some reason to doubt +whether they are really a priori; but he cannot on this account +declare them to be impossible, and affirm the nullity of the steps +which reason may have taken under their guidance. He can only say: +If we perceived their origin and their authenticity, we should be able +to determine the extent and limits of reason; but, till we can do +this, all propositions regarding the latter are mere random +assertions. In this view, the doubt respecting all dogmatical +philosophy, which proceeds without the guidance of criticism, is +well grounded; but we cannot therefore deny to reason the ability to +construct a sound philosophy, when the way has been prepared by a +thorough critical investigation. All the conceptions produced, and +all the questions raised, by pure reason, do not lie in the sphere +of experience, but in that of reason itself, and hence they must be +solved, and shown to be either valid or inadmissible, by that faculty. +We have no right to decline the solution of such problems, on the +ground that the solution can be discovered only from the nature of +things, and under pretence of the limitation of human faculties, for +reason is the sole creator of all these ideas, and is therefore +bound either to establish their validity or to expose their illusory +nature. + +The polemic of scepticism is properly directed against the +dogmatist, who erects a system of philosophy without having examined +the fundamental objective principles on which it is based, for the +purpose of evidencing the futility of his designs, and thus bringing +him to a knowledge of his own powers. But, in itself, scepticism +does not give us any certain information in regard to the bounds of +our knowledge. All unsuccessful dogmatical attempts of reason are +facia, which it is always useful to submit to the censure of the +sceptic. But this cannot help us to any decision regarding the +expectations which reason cherishes of better success in future +endeavours; the investigations of scepticism cannot, therefore, settle +the dispute regarding the rights and powers of human reason. + +Hume is perhaps the ablest and most ingenious of all sceptical +philosophers, and his writings have, undoubtedly, exerted the most +powerful influence in awakening reason to a thorough investigation +into its own powers. It will, therefore, well repay our labours to +consider for a little the course of reasoning which he followed and +the errors into which he strayed, although setting out on the path +of truth and certitude. + +Hume was probably aware, although he never clearly developed the +notion, that we proceed in judgements of a certain class beyond our +conception if the object. I have termed this kind of judgement +synthetical. As regard the manner in which I pass beyond my conception +by the aid of experience, no doubts can be entertained. Experience +is itself a synthesis of perceptions; and it employs perceptions to +increment the conception, which I obtain by means of another +perception. But we feel persuaded that we are able to proceed beyond +a conception, and to extend our cognition a priori. We attempt this +in two ways--either, through the pure understanding, in relation to +that which may become an object of experience, or, through pure +reason, in relation to such properties of things, or of the +existence of things, as can never be presented in any experience. This +sceptical philosopher did not distinguish these two kinds of +judgements, as he ought to have done, but regarded this augmentation +of conceptions, and, if we may so express ourselves, the spontaneous +generation of understanding and reason, independently of the +impregnation of experience, as altogether impossible. The so-called +a priori principles of these faculties he consequently held to be +invalid and imaginary, and regarded them as nothing but subjective +habits of thought originating in experience, and therefore purely +empirical and contingent rules, to which we attribute a spurious +necessity and universality. In support of this strange assertion, he +referred us to the generally acknowledged principle of the relation +between cause and effect. No faculty of the mind can conduct us from +the conception of a thing to the existence of something else; and +hence he believed he could infer that, without experience, we +possess no source from which we can augment a conception, and no +ground sufficient to justify us in framing a judgement that is to +extend our cognition a priori. That the light of the sun, which shines +upon a piece of wax, at the same time melts it, while it hardens clay, +no power of the understanding could infer from the conceptions which +we previously possessed of these substances; much less is there any +a priori law that could conduct us to such a conclusion, which +experience alone can certify. On the other hand, we have seen in our +discussion of transcendental logic, that, although we can never +proceed immediately beyond the content of the conception which is +given us, we can always cognize completely a priori--in relation, +however, to a third term, namely, possible experience--the law of +its connection with other things. For example, if I observe that a +piece of wax melts, I can cognize a priori that there must have been +something (the sun's heat) preceding, which this law; although, +without the aid of experience, I could not cognize a priori and in +a determinate manner either the cause from the effect, or the effect +from the cause. Hume was, therefore, wrong in inferring, from the +contingency of the determination according to law, the contingency +of the law itself; and the passing beyond the conception of a thing +to possible experience (which is an a priori proceeding, constituting +the objective reality of the conception), he confounded with our synthesis +of objects in actual experience, which is always, of course, +empirical. Thus, too, he regarded the principle of affinity, which +has its seat in the understanding and indicates a necessary connection, +as a mere rule of association, lying in the imitative faculty of +imagination, which can present only contingent, and not objective +connections. + +The sceptical errors of this remarkably acute thinker arose +principally from a defect, which was common to him with the +dogmatists, namely, that he had never made a systematic review of +all the different kinds of a priori synthesis performed by the +understanding. Had he done so, he would have found, to take one +example among many, that the principle of permanence was of this +character, and that it, as well as the principle of causality, +anticipates experience. In this way he might have been able to +describe the determinate limits of the a priori operations of +understanding and reason. But he merely declared the understanding +to be limited, instead of showing what its limits were; he created +a general mistrust in the power of our faculties, without giving us +any determinate knowledge of the bounds of our necessary and +unavoidable ignorance; he examined and condemned some of the +principles of the understanding, without investigating all its +powers with the completeness necessary to criticism. He denies, with +truth, certain powers to the understanding, but he goes further, and +declares it to be utterly inadequate to the a priori extension of +knowledge, although he has not fully examined all the powers which +reside in the faculty; and thus the fate which always overtakes +scepticism meets him too. That is to say, his own declarations are +doubted, for his objections were based upon facta, which are +contingent, and not upon principles, which can alone demonstrate the +necessary invalidity of all dogmatical assertions. + +As Hume makes no distinction between the well-grounded claims of the +understanding and the dialectical pretensions of reason, against +which, however, his attacks are mainly directed, reason does not +feel itself shut out from all attempts at the extension of a priori +cognition, and hence it refuses, in spite of a few checks in this or +that quarter, to relinquish such efforts. For one naturally arms +oneself to resist an attack, and becomes more obstinate in the resolve +to establish the claims he has advanced. But a complete review of +the powers of reason, and the conviction thence arising that we are +in possession of a limited field of action, while we must admit the +vanity of higher claims, puts an end to all doubt and dispute, and +induces reason to rest satisfied with the undisturbed possession of +its limited domain. + +To the uncritical dogmatist, who has not surveyed the sphere of +his understanding, nor determined, in accordance with principles, +the limits of possible cognition, who, consequently, is ignorant of +his own powers, and believes he will discover them by the attempts +he makes in the field of cognition, these attacks of scepticism are +not only dangerous, but destructive. For if there is one proposition +in his chain of reasoning which be he cannot prove, or the fallacy +in which he cannot evolve in accordance with a principle, suspicion +falls on all his statements, however plausible they may appear. + +And thus scepticism, the bane of dogmatical philosophy, conducts +us to a sound investigation into the understanding and the reason. +When we are thus far advanced, we need fear no further +attacks; for the limits of our domain are clearly marked out, and we +can make no claims nor become involved in any disputes regarding the +region that lies beyond these limits. Thus the sceptical procedure +in philosophy does not present any solution of the problems of reason, +but it forms an excellent exercise for its powers, awakening its +circumspection, and indicating the means whereby it may most fully +establish its claims to its legitimate possessions. + + + +SECTION III. The Discipline of Pure Reason in Hypothesis. + +This critique of reason has now taught us that all its efforts to +extend the bounds of knowledge, by means of pure speculation, are +utterly fruitless. So much the wider field, it may appear, lies open +to hypothesis; as, where we cannot know with certainty, we are at +liberty to make guesses and to form suppositions. + +Imagination may be allowed, under the strict surveillance of reason, +to invent suppositions; but, these must be based on something that +is perfectly certain--and that is the possibility of the object. If +we are well assured upon this point, it is allowable to have recourse +to supposition in regard to the reality of the object; but this +supposition must, unless it is utterly groundless, be connected, as +its ground of explanation, with that which is really given and +absolutely certain. Such a supposition is termed a hypothesis. + +It is beyond our power to form the least conception a priori of +the possibility of dynamical connection in phenomena; and the category +of the pure understanding will not enable us to excogitate any +such connection, but merely helps us to understand it, when we meet +with it in experience. For this reason we cannot, in accordance with +the categories, imagine or invent any object or any property of an +object not given, or that may not be given in experience, and employ +it in a hypothesis; otherwise, we should be basing our chain of +reasoning upon mere chimerical fancies, and not upon conceptions of +things. Thus, we have no right to assume the existence of new +powers, not existing in nature--for example, an understanding with +a non-sensuous intuition, a force of attraction without contact, or +some new kind of substances occupying space, and yet without the property +of impenetrability--and, consequently, we cannot assume that there +is any other kind of community among substances than that observable +in experience, any kind of presence than that in space, or any kind +of duration than that in time. In one word, the conditions of possible +experience are for reason the only conditions of the possibility of +things; reason cannot venture to form, independently of these +conditions, any conceptions of things, because such conceptions, +although not self-contradictory, are without object and without +application. + +The conceptions of reason are, as we have already shown, mere ideas, +and do not relate to any object in any kind of experience. At the same +time, they do not indicate imaginary or possible objects. They are +purely problematical in their nature and, as aids to the heuristic +exercise of the faculties, form the basis of the regulative principles +for the systematic employment of the understanding in the field of +experience. If we leave this ground of experience, they become mere +fictions of thought, the possibility of which is quite indemonstrable; +and they cannot, consequently, be employed as hypotheses in the +explanation of real phenomena. It is quite admissible to cogitate +the soul as simple, for the purpose of enabling ourselves to employ +the idea of a perfect and necessary unity of all the faculties of +the mind as the principle of all our inquiries into its internal +phenomena, although we cannot cognize this unity in concreto. But to +assume that the soul is a simple substance (a transcendental +conception) would be enouncing a proposition which is not only +indemonstrable--as many physical hypotheses are--but a proposition +which is purely arbitrary, and in the highest degree rash. The +simple is never presented in experience; and, if by substance is +here meant the permanent object of sensuous intuition, the possibility +of a simple phenomenon is perfectly inconceivable. Reason affords no +good grounds for admitting the existence of intelligible beings, or +of intelligible properties of sensuous things, although--as we have +no conception either of their possibility or of their impossibility--it +will always be out of our power to affirm dogmatically that they do +not exist. In the explanation of given phenomena, no other things +and no other grounds of explanation can be employed than those which +stand in connection with the given phenomena according to the known +laws of experience. A transcendental hypothesis, in which a mere +idea of reason is employed to explain the phenomena of nature, would +not give us any better insight into a phenomenon, as we should be +trying to explain what we do not sufficiently understand from known +empirical principles, by what we do not understand at all. The +principles of such a hypothesis might conduce to the satisfaction of +reason, but it would not assist the understanding in its application +to objects. Order and conformity to aims in the sphere of nature +must be themselves explained upon natural grounds and according to +natural laws; and the wildest hypotheses, if they are only physical, +are here more admissible than a hyperphysical hypothesis, such as that +of a divine author. For such a hypothesis would introduce the +principle of ignava ratio, which requires us to give up the search +for causes that might be discovered in the course of experience and +to rest satisfied with a mere idea. As regards the absolute totality +of the grounds of explanation in the series of these causes, this can +be no hindrance to the understanding in the case of phenomena; +because, as they are to us nothing more than phenomena, we have no +right to look for anything like completeness in the synthesis of the +series of their conditions. + +Transcendental hypotheses are therefore inadmissible; and we +cannot use the liberty of employing, in the absence of physical, +hyperphysical grounds of explanation. And this for two reasons; first, +because such hypothesis do not advance reason, but rather stop it in +its progress; secondly, because this licence would render fruitless +all its exertions in its own proper sphere, which is that of +experience. For, when the explanation of natural phenomena happens +to be difficult, we have constantly at hand a transcendental ground +of explanation, which lifts us above the necessity of investigating +nature; and our inquiries are brought to a close, not because we +have obtained all the requisite knowledge, but because we abut upon +a principle which is incomprehensible and which, indeed, is so far +back in the track of thought as to contain the conception of the +absolutely primal being. + +The next requisite for the admissibility of a hypothesis is its +sufficiency. That is, it must determine a priori the consequences +which are given in experience and which are supposed to follow from +the hypothesis itself. If we require to employ auxiliary hypotheses, +the suspicion naturally arises that they are mere fictions; because +the necessity for each of them requires the same justification as in +the case of the original hypothesis, and thus their testimony is +invalid. If we suppose the existence of an infinitely perfect cause, +we possess sufficient grounds for the explanation of the conformity +to aims, the order and the greatness which we observe in the universe; +but we find ourselves obliged, when we observe the evil in the world +and the exceptions to these laws, to employ new hypothesis in +support of the original one. We employ the idea of the simple nature +of the human soul as the foundation of all the theories we may form +of its phenomena; but when we meet with difficulties in our way, when +we observe in the soul phenomena similar to the changes which take +place in matter, we require to call in new auxiliary hypotheses. These +may, indeed, not be false, but we do not know them to be true, because +the only witness to their certitude is the hypothesis which they +themselves have been called in to explain. + +We are not discussing the above-mentioned assertions regarding the +immaterial unity of the soul and the existence of a Supreme Being as +dogmata, which certain philosophers profess to demonstrate a priori, +but purely as hypotheses. In the former case, the dogmatist must +take care that his arguments possess the apodeictic certainty of a +demonstration. For the assertion that the reality of such ideas is +probable is as absurd as a proof of the probability of a proposition +in geometry. Pure abstract reason, apart from all experience, can +either cognize nothing at all; and hence the judgements it enounces +are never mere opinions, they are either apodeictic certainties, or +declarations that nothing can be known on the subject. Opinions and +probable judgements on the nature of things can only be employed to +explain given phenomena, or they may relate to the effect, in +accordance with empirical laws, of an actually existing cause. In +other words, we must restrict the sphere of opinion to the world of +experience and nature. Beyond this region opinion is mere invention; +unless we are groping about for the truth on a path not yet fully +known, and have some hopes of stumbling upon it by chance. + +But, although hypotheses are inadmissible in answers to the +questions of pure speculative reason, they may be employed in the +defence of these answers. That is to say, hypotheses are admissible +in polemic, but not in the sphere of dogmatism. By the defence of +statements of this character, I do not mean an attempt at +discovering new grounds for their support, but merely the refutation +of the arguments of opponents. All a priori synthetical propositions +possess the peculiarity that, although the philosopher who maintains +the reality of the ideas contained in the proposition is not in +possession of sufficient knowledge to establish the certainty of his +statements, his opponent is as little able to prove the truth of the +opposite. This equality of fortune does not allow the one party to +be superior to the other in the sphere of speculative cognition; and +it is this sphere, accordingly, that is the proper arena of these +endless speculative conflicts. But we shall afterwards show that, in +relation to its practical exercise, Reason has the right of +admitting what, in the field of pure speculation, she would not be +justified in supposing, except upon perfectly sufficient grounds; +because all such suppositions destroy the necessary completeness of +speculation--a condition which the practical reason, however, does +not consider to be requisite. In this sphere, therefore, Reason is +mistress of a possession, her title to which she does not require to +prove--which, in fact, she could not do. The burden of proof +accordingly rests upon the opponent. But as he has just as little +knowledge regarding the subject discussed, and is as little able to +prove the non-existence of the object of an idea, as the philosopher +on the other side is to demonstrate its reality, it is evident that +there is an advantage on the side of the philosopher who maintains +his proposition as a practically necessary supposition (melior est +conditio possidentis). For he is at liberty to employ, in +self-defence, the same weapons as his opponent makes use of in +attacking him; that is, he has a right to use hypotheses not for the +purpose of supporting the arguments in favour of his own propositions, +but to show that his opponent knows no more than himself regarding +the subject under 'discussion and cannot boast of any speculative +advantage. + +Hypotheses are, therefore, admissible in the sphere of pure reason +only as weapons for self-defence, and not as supports to dogmatical +assertions. But the opposing party we must always seek for in +ourselves. For speculative reason is, in the sphere of +transcendentalism, dialectical in its own nature. The difficulties +and objections we have to fear lie in ourselves. They are like old +but never superannuated claims; and we must seek them out, and settle +them once and for ever, if we are to expect a permanent peace. External +tranquility is hollow and unreal. The root of these contradictions, +which lies in the nature of human reason, must be destroyed; and +this can only be done by giving it, in the first instance, freedom +to grow, nay, by nourishing it, that it may send out shoots, and +thus betray its own existence. It is our duty, therefore, to try to +discover new objections, to put weapons in the bands of our +opponent, and to grant him the most favourable position in the arena +that he can wish. We have nothing to fear from these concessions; on +the contrary, we may rather hope that we shall thus make ourselves +master of a possession which no one will ever venture to dispute. + +The thinker requires, to be fully equipped, the hypotheses of pure +reason, which, although but leaden weapons (for they have not been +steeled in the armoury of experience), are as useful as any that can +be employed by his opponents. If, accordingly, we have assumed, from +a non-speculative point of view, the immaterial nature of the soul, +and are met by the objection that experience seems to prove that the +growth and decay of our mental faculties are mere modifications of +the sensuous organism--we can weaken the force of this objection by +the assumption that the body is nothing but the fundamental phenomenon, +to which, as a necessary condition, all sensibility, and consequently +all thought, relates in the present state of our existence; and that +the separation of soul and body forms the conclusion of the sensuous +exercise of our power of cognition and the beginning of the +intellectual. The body would, in this view of the question, be +regarded, not as the cause of thought, but merely as its restrictive +condition, as promotive of the sensuous and animal, but as a hindrance +to the pure and spiritual life; and the dependence of the animal +life on the constitution of the body, would not prove that the whole +life of man was also dependent on the state of the organism. We +might go still farther, and discover new objections, or carry out to +their extreme consequences those which have already been adduced. + +Generation, in the human race as well as among the irrational +animals, depends on so many accidents--of occasion, of proper +sustenance, of the laws enacted by the government of a country of vice +even, that it is difficult to believe in the eternal existence of a +being whose life has begun under circumstances so mean and trivial, +and so entirely dependent upon our own control. As regards the +continuance of the existence of the whole race, we need have no +difficulties, for accident in single cases is subject to general laws; +but, in the case of each individual, it would seem as if we could +hardly expect so wonderful an effect from causes so insignificant. +But, in answer to these objections, we may adduce the transcendental +hypothesis that all life is properly intelligible, and not subject +to changes of time, and that it neither began in birth, nor will end +in death. We may assume that this life is nothing more than a sensuous +representation of pure spiritual life; that the whole world of sense +is but an image, hovering before the faculty of cognition which we +exercise in this sphere, and with no more objective reality than a +dream; and that if we could intuite ourselves and other things as they +really are, we should see ourselves in a world of spiritual natures, +our connection with which did not begin at our birth and will not +cease with the destruction of the body. And so on. + +We cannot be said to know what has been above asserted, nor do we +seriously maintain the truth of these assertions; and the notions +therein indicated are not even ideas of reason, they are purely +fictitious conceptions. But this hypothetical procedure is in +perfect conformity with the laws of reason. Our opponent mistakes +the absence of empirical conditions for a proof of the complete +impossibility of all that we have asserted; and we have to show him +that he has not exhausted the whole sphere of possibility and that +he can as little compass that sphere by the laws of experience and +nature, as we can lay a secure foundation for the operations of reason +beyond the region of experience. Such hypothetical defences against +the pretensions of an opponent must not be regarded as declarations +of opinion. The philosopher abandons them, so soon as the opposite +party renounces its dogmatical conceit. To maintain a simply +negative position in relation to propositions which rest on an +insecure foundation, well befits the moderation of a true philosopher; +but to uphold the objections urged against an opponent as proofs of +the opposite statement is a proceeding just as unwarrantable and +arrogant as it is to attack the position of a philosopher who advances +affirmative propositions regarding such a subject. + +It is evident, therefore, that hypotheses, in the speculative +sphere, are valid, not as independent propositions, but only +relatively to opposite transcendent assumptions. For, to make the +principles of possible experience conditions of the possibility of +things in general is just as transcendent a procedure as to maintain +the objective reality of ideas which can be applied to no objects +except such as lie without the limits of possible experience. The +judgements enounced by pure reason must be necessary, or they must +not be enounced at all. Reason cannot trouble herself with opinions. +But the hypotheses we have been discussing are merely problematical +judgements, which can neither be confuted nor proved; while, +therefore, they are not personal opinions, they are indispensable as +answers to objections which are liable to be raised. But we must +take care to confine them to this function, and guard against any +assumption on their part of absolute validity, a proceeding which +would involve reason in inextricable difficulties and contradictions. + + + +SECTION IV. The Discipline of Pure Reason in Relation to Proofs. + +It is a peculiarity, which distinguishes the proofs of transcendental +synthetical propositions from those of all other a priori synthetical +cognitions, that reason, in the case of the former, does not apply its +conceptions directly to an object, but is first obliged to prove, a +priori, the objective validity of these conceptions and the possibility +of their syntheses. This is not merely a prudential rule, it is +essential to the very possibility of the proof of a transcendental +proposition. If I am required to pass, a priori, beyond the conception +of an object, I find that it is utterly impossible without the guidance +of something which is not contained in the conception. In mathematics, +it is a priori intuition that guides my synthesis; and, in this case, +all our conclusions may be drawn immediately from pure intuition. In +transcendental cognition, so long as we are dealing only with +conceptions of the understanding, we are guided by possible experience. +That is to say, a proof in the sphere of transcendental cognition does +not show that the given conception (that of an event, for example) +leads directly to another conception (that of a cause)--for this would +be a saltus which nothing can justify; but it shows that experience +itself, and consequently the object of experience, is impossible +without the connection indicated by these conceptions. It follows that +such a proof must demonstrate the possibility of arriving, +synthetically and a priori, at a certain knowledge of things, which was +not contained in our conceptions of these things. Unless we pay +particular attention to this requirement, our proofs, instead of +pursuing the straight path indicated by reason, follow the tortuous +road of mere subjective association. The illusory conviction, which +rests upon subjective causes of association, and which is considered as +resulting from the perception of a real and objective natural affinity, +is always open to doubt and suspicion. For this reason, all the +attempts which have been made to prove the principle of sufficient +reason, have, according to the universal admission of philosophers, +been quite unsuccessful; and, before the appearance of transcendental +criticism, it was considered better, as this principle could not be +abandoned, to appeal boldly to the common sense of mankind (a +proceeding which always proves that the problem, which reason ought to +solve, is one in which philosophers find great difficulties), rather +than attempt to discover new dogmatical proofs. + +But, if the proposition to be proved is a proposition of pure +reason, and if I aim at passing beyond my empirical conceptions by +the aid of mere ideas, it is necessary that the proof should first +show that such a step in synthesis is possible (which it is not), before +it proceeds to prove the truth of the proposition itself. The so-called +proof of the simple nature of the soul from the unity of apperception, +is a very plausible one. But it contains no answer to the objection, +that, as the notion of absolute simplicity is not a conception which +is directly applicable to a perception, but is an idea which must be +inferred--if at all--from observation, it is by no means evident how +the mere fact of consciousness, which is contained in all thought, +although in so far a simple representation, can conduct me to the +consciousness and cognition of a thing which is purely a thinking +substance. When I represent to my mind the power of my body as in +motion, my body in this thought is so far absolute unity, and my +representation of it is a simple one; and hence I can indicate this +representation by the motion of a point, because I have made +abstraction of the size or volume of the body. But I cannot hence +infer that, given merely the moving power of a body, the body may be +cogitated as simple substance, merely because the representation in +my mind takes no account of its content in space, and is consequently +simple. The simple, in abstraction, is very different from the +objectively simple; and hence the Ego, which is simple in the first +sense, may, in the second sense, as indicating the soul itself, be +a very complex conception, with a very various content. Thus it is +evident that in all such arguments there lurks a paralogism. We +guess (for without some such surmise our suspicion would not be +excited in reference to a proof of this character) at the presence +of the paralogism, by keeping ever before us a criterion of the +possibility of those synthetical propositions which aim at proving +more than experience can teach us. This criterion is obtained from +the observation that such proofs do not lead us directly from the +subject of the proposition to be proved to the required predicate, +but find it necessary to presuppose the possibility of extending our +cognition a priori by means of ideas. We must, accordingly, always +use the greatest caution; we require, before attempting any proof, +to consider how it is possible to extend the sphere of cognition by +the operations of pure reason, and from what source we are to derive +knowledge, which is not obtained from the analysis of conceptions, +nor relates, by anticipation, to possible experience. We shall thus +spare ourselves much severe and fruitless labour, by not expecting +from reason what is beyond its power, or rather by subjecting it to +discipline, and teaching it to moderate its vehement desires for the +extension of the sphere of cognition. + +The first rule for our guidance is, therefore, not to attempt a +transcendental proof, before we have considered from what source we +are to derive the principles upon which the proof is to be based, +and what right we have to expect that our conclusions from these +principles will be veracious. If they are principles of the +understanding, it is vain to expect that we should attain by their +means to ideas of pure reason; for these principles are valid only +in regard to objects of possible experience. If they are principles +of pure reason, our labour is alike in vain. For the principles of +reason, if employed as objective, are without exception dialectical +and possess no validity or truth, except as regulative principles of +the systematic employment of reason in experience. But when such +delusive proof are presented to us, it is our duty to meet them with +the non liquet of a matured judgement; and, although we are unable +to expose the particular sophism upon which the proof is based, we +have a right to demand a deduction of the principles employed in it; +and, if these principles have their origin in pure reason alone, +such a deduction is absolutely impossible. And thus it is +unnecessary that we should trouble ourselves with the exposure and +confutation of every sophistical illusion; we may, at once, bring +all dialectic, which is inexhaustible in the production of +fallacies, before the bar of critical reason, which tests the +principles upon which all dialectical procedure is based. The second +peculiarity of transcendental proof is that a transcendental +proposition cannot rest upon more than a single proof. If I am drawing +conclusions, not from conceptions, but from intuition corresponding +to a conception, be it pure intuition, as in mathematics, or empirical, +as in natural science, the intuition which forms the basis of my +inferences presents me with materials for many synthetical +propositions, which I can connect in various modes, while, as it is +allowable to proceed from different points in the intention, I can +arrive by different paths at the same proposition. + +But every transcendental proposition sets out from a conception, and +posits the synthetical condition of the possibility of an object +according to this conception. There must, therefore, be but one ground +of proof, because it is the conception alone which determines the +object; and thus the proof cannot contain anything more than the +determination of the object according to the conception. In our +Transcendental Analytic, for example, we inferred the principle: Every +event has a cause, from the only condition of the objective +possibility of our conception of an event. This is that an event +cannot be determined in time, and consequently cannot form a part of +experience, unless it stands under this dynamical law. This is the +only possible ground of proof; for our conception of an event +possesses objective validity, that is, is a true conception, only +because the law of causality determines an object to which it can +refer. Other arguments in support of this principle have been +attempted--such as that from the contingent nature of a phenomenon; +but when this argument is considered, we can discover no criterion +of contingency, except the fact of an event--of something happening, +that is to say, the existence which is preceded by the non-existence +of an object, and thus we fall back on the very thing to be proved. +If the proposition: "Every thinking being is simple," is to be proved, +we keep to the conception of the ego, which is simple, and to which +all thought has a relation. The same is the case with the transcendental +proof of the existence of a Deity, which is based solely upon the +harmony and reciprocal fitness of the conceptions of an ens +realissimum and a necessary being, and cannot be attempted in any +other manner. + +This caution serves to simplify very much the criticism of all +propositions of reason. When reason employs conceptions alone, only +one proof of its thesis is possible, if any. When, therefore, the +dogmatist advances with ten arguments in favour of a proposition, we +may be sure that not one of them is conclusive. For if he possessed +one which proved the proposition he brings forward to demonstration- +as must always be the case with the propositions of pure reason- +what need is there for any more? His intention can only be similar +to that of the advocate who had different arguments for different +judges; this availing himself of the weakness of those who examine +his arguments, who, without going into any profound investigation, +adopt the view of the case which seems most probable at first sight +and decide according to it. + +The third rule for the guidance of pure reason in the conduct of a +proof is that all transcendental proofs must never be apagogic or +indirect, but always ostensive or direct. The direct or ostensive +proof not only establishes the truth of the proposition to be +proved, but exposes the grounds of its truth; the apagogic, on the +other hand, may assure us of the truth of the proposition, but it +cannot enable us to comprehend the grounds of its possibility. The +latter is, accordingly, rather an auxiliary to an argument, than a +strictly philosophical and rational mode of procedure. In one respect, +however, they have an advantage over direct proofs, from the fact that +the mode of arguing by contradiction, which they employ, renders our +understanding of the question more clear, and approximates the proof +to the certainty of an intuitional demonstration. + +The true reason why indirect proofs are employed in different +sciences is this. When the grounds upon which we seek to base a +cognition are too various or too profound, we try whether or not we +may not discover the truth of our cognition from its consequences. +The modus ponens of reasoning from the truth of its inferences to the +truth of a proposition would be admissible if all the inferences +that can be drawn from it are known to be true; for in this case there +can be only one possible ground for these inferences, and that is +the true one. But this is a quite impracticable procedure, as it +surpasses all our powers to discover all the possible inferences +that can be drawn from a proposition. But this mode of reasoning is +employed, under favour, when we wish to prove the truth of an +hypothesis; in which case we admit the truth of the conclusion- +which is supported by analogy--that, if all the inferences we have +drawn and examined agree with the proposition assumed, all other +possible inferences will also agree with it. But, in this way, an +hypothesis can never be established as a demonstrated truth. The modus +tollens of reasoning from known inferences to the unknown proposition, +is not only a rigorous, but a very easy mode of proof. For, if it +can be shown that but one inference from a proposition is false, +then the proposition must itself be false. Instead, then, of +examining, in an ostensive argument, the whole series of the grounds +on which the truth of a proposition rests, we need only take the +opposite of this proposition, and if one inference from it be false, +then must the opposite be itself false; and, consequently, the +proposition which we wished to prove must be true. + +The apagogic method of proof is admissible only in those sciences +where it is impossible to mistake a subjective representation for an +objective cognition. Where this is possible, it is plain that the +opposite of a given proposition may contradict merely the subjective +conditions of thought, and not the objective cognition; or it may +happen that both propositions contradict each other only under a +subjective condition, which is incorrectly considered to be objective, +and, as the condition is itself false, both propositions may be false, +and it will, consequently, be impossible to conclude the truth of +the one from the falseness of the other. + +In mathematics such subreptions are impossible; and it is in this +science, accordingly, that the indirect mode of proof has its true +place. In the science of nature, where all assertion is based upon +empirical intuition, such subreptions may be guarded against by the +repeated comparison of observations; but this mode of proof is of +little value in this sphere of knowledge. But the transcendental +efforts of pure reason are all made in the sphere of the subjective, +which is the real medium of all dialectical illusion; and thus +reason endeavours, in its premisses, to impose upon us subjective +representations for objective cognitions. In the transcendental sphere +of pure reason, then, and in the case of synthetical propositions, +it is inadmissible to support a statement by disproving the +counter-statement. For only two cases are possible; either, the +counter-statement is nothing but the enouncement of the +inconsistency of the opposite opinion with the subjective conditions +of reason, which does not affect the real case (for example, we cannot +comprehend the unconditioned necessity of the existence of a being, +and hence every speculative proof of the existence of such a being +must be opposed on subjective grounds, while the possibility of this +being in itself cannot with justice be denied); or, both propositions, +being dialectical in their nature, are based upon an impossible +conception. In this latter case the rule applies: non entis nulla sunt +predicata; that is to say, what we affirm and what we deny, respecting +such an object, are equally untrue, and the apagogic mode of +arriving at the truth is in this case impossible. If, for example, +we presuppose that the world of sense is given in itself in its +totality, it is false, either that it is infinite, or that it is +finite and limited in space. Both are false, because the hypothesis +is false. For the notion of phenomena (as mere representations) which +are given in themselves (as objects) is self-contradictory; and the +infinitude of this imaginary whole would, indeed, be unconditioned, +but would be inconsistent (as everything in the phenomenal world is +conditioned) with the unconditioned determination and finitude of +quantities which is presupposed in our conception. + +The apagogic mode of proof is the true source of those illusions +which have always had so strong an attraction for the admirers of +dogmatical philosophy. It may be compared to a champion who +maintains the honour and claims of the party he has adopted by +offering battle to all who doubt the validity of these claims and +the purity of that honour; while nothing can be proved in this way, +except the respective strength of the combatants, and the advantage, +in this respect, is always on the side of the attacking party. +Spectators, observing that each party is alternately conqueror and +conquered, are led to regard the subject of dispute as beyond the +power of man to decide upon. But such an opinion cannot be +justified; and it is sufficient to apply to these reasoners the +remark: + + Non defensoribus istis + Tempus eget. + +Each must try to establish his assertions by a transcendental +deduction of the grounds of proof employed in his argument, and thus +enable us to see in what way the claims of reason may be supported. +If an opponent bases his assertions upon subjective grounds, he may +be refuted with ease; not, however to the advantage of the dogmatist, +who likewise depends upon subjective sources of cognition and is in +like manner driven into a corner by his opponent. But, if parties employ +the direct method of procedure, they will soon discover the +difficulty, nay, the impossibility of proving their assertions, and +will be forced to appeal to prescription and precedence; or they will, +by the help of criticism, discover with ease the dogmatical +illusions by which they had been mocked, and compel reason to renounce +its exaggerated pretensions to speculative insight and to confine +itself within the limits of its proper sphere--that of practical +principles. + + + +CHAPTER II. The Canon of Pure Reason. + +It is a humiliating consideration for human reason that it is +incompetent to discover truth by means of pure speculation, but, on +the contrary, stands in need of discipline to check its deviations +from the straight path and to expose the illusions which it +originates. But, on the other hand, this consideration ought to +elevate and to give it confidence, for this discipline is exercised +by itself alone, and it is subject to the censure of no other power. +The bounds, moreover, which it is forced to set to its speculative +exercise, form likewise a check upon the fallacious pretensions of +opponents; and thus what remains of its possessions, after these +exaggerated claims have been disallowed, is secure from attack or +usurpation. The greatest, and perhaps the only, use of all +philosophy of pure reason is, accordingly, of a purely negative +character. It is not an organon for the extension, but a discipline +for the determination, of the limits of its exercise; and without +laying claim to the discovery of new truth, it has the modest merit +of guarding against error. + +At the same time, there must be some source of positive cognitions +which belong to the domain of pure reason and which become the +causes of error only from our mistaking their true character, while +they form the goal towards which reason continually strives. How +else can we account for the inextinguishable desire in the human +mind to find a firm footing in some region beyond the limits of the +world of experience? It hopes to attain to the possession of a +knowledge in which it has the deepest interest. It enters upon the +path of pure speculation; but in vain. We have some reason, however, +to expect that, in the only other way that lies open to it--the path +of practical reason--it may meet with better success. + +I understand by a canon a list of the a priori principles of the +proper employment of certain faculties of cognition. Thus general +logic, in its analytical department, is a formal canon for the +faculties of understanding and reason. In the same way, Transcendental +Analytic was seen to be a canon of the pure understanding; for it +alone is competent to enounce true a priori synthetical cognitions. +But, when no proper employment of a faculty of cognition is +possible, no canon can exist. But the synthetical cognition of pure +speculative reason is, as has been shown, completely impossible. There +cannot, therefore, exist any canon for the speculative exercise of +this faculty--for its speculative exercise is entirely dialectical; +and, consequently, transcendental logic, in this respect, is merely +a discipline, and not a canon. If, then, there is any proper mode of +employing the faculty of pure reason--in which case there must be a +canon for this faculty--this canon will relate, not to the +speculative, but to the practical use of reason. This canon we now +proceed to investigate. + + + +SECTION I. Of the Ultimate End of the Pure Use of Reason. + +There exists in the faculty of reason a natural desire to venture +beyond the field of experience, to attempt to reach the utmost +bounds of all cognition by the help of ideas alone, and not to rest +satisfied until it has fulfilled its course and raised the sum of +its cognitions into a self-subsistent systematic whole. Is the +motive for this endeavour to be found in its speculative, or in its +practical interests alone? + +Setting aside, at present, the results of the labours of pure reason +in its speculative exercise, I shall merely inquire regarding the +problems the solution of which forms its ultimate aim, whether reached +or not, and in relation to which all other aims are but partial and +intermediate. These highest aims must, from the nature of reason, +possess complete unity; otherwise the highest interest of humanity +could not be successfully promoted. + +The transcendental speculation of reason relates to three things: +the freedom of the will, the immortality of the soul, and the +existence of God. The speculative interest which reason has in those +questions is very small; and, for its sake alone, we should not +undertake the labour of transcendental investigation--a labour full +of toil and ceaseless struggle. We should be loth to undertake this +labour, because the discoveries we might make would not be of the +smallest use in the sphere of concrete or physical investigation. We +may find out that the will is free, but this knowledge only relates +to the intelligible cause of our volition. As regards the phenomena +or expressions of this will, that is, our actions, we are bound, in +obedience to an inviolable maxim, without which reason cannot be +employed in the sphere of experience, to explain these in the same +way as we explain all the other phenomena of nature, that is to say, +according to its unchangeable laws. We may have discovered the +spirituality and immortality of the soul, but we cannot employ this +knowledge to explain the phenomena of this life, nor the peculiar +nature of the future, because our conception of an incorporeal +nature is purely negative and does not add anything to our +knowledge, and the only inferences to be drawn from it are purely +fictitious. If, again, we prove the existence of a supreme +intelligence, we should be able from it to make the conformity to aims +existing in the arrangement of the world comprehensible; but we should +not be justified in deducing from it any particular arrangement or +disposition, or inferring any where it is not perceived. For it is +a necessary rule of the speculative use of reason that we must not +overlook natural causes, or refuse to listen to the teaching of +experience, for the sake of deducing what we know and perceive from +something that transcends all our knowledge. In one word, these +three propositions are, for the speculative reason, always +transcendent, and cannot be employed as immanent principles in +relation to the objects of experience; they are, consequently, of no +use to us in this sphere, being but the valueless results of the +severe but unprofitable efforts of reason. + +If, then, the actual cognition of these three cardinal propositions is +perfectly useless, while Reason uses her utmost endeavours to induce us +to admit them, it is plain that their real value and importance relate +to our practical, and not to our speculative interest. + +I term all that is possible through free will, practical. But if the +conditions of the exercise of free volition are empirical, reason +can have only a regulative, and not a constitutive, influence upon +it, and is serviceable merely for the introduction of unity into its +empirical laws. In the moral philosophy of prudence, for example, +the sole business of reason is to bring about a union of all the ends, +which are aimed at by our inclinations, into one ultimate end--that +of happiness--and to show the agreement which should exist among the +means of attaining that end. In this sphere, accordingly, reason +cannot present to us any other than pragmatical laws of free action, +for our guidance towards the aims set up by the senses, and is +incompetent to give us laws which are pure and determined completely +a priori. On the other hand, pure practical laws, the ends of which +have been given by reason entirely a priori, and which are not +empirically conditioned, but are, on the contrary, absolutely +imperative in their nature, would be products of pure reason. Such +are the moral laws; and these alone belong to the sphere of the +practical exercise of reason, and admit of a canon. + +All the powers of reason, in the sphere of what may be termed pure +philosophy, are, in fact, directed to the three above-mentioned +problems alone. These again have a still higher end--the answer to +the question, what we ought to do, if the will is free, if there is +a God and a future world. Now, as this problem relates to our in +reference to the highest aim of humanity, it is evident that the +ultimate intention of nature, in the constitution of our reason, has +been directed to the moral alone. + +We must take care, however, in turning our attention to an object +which is foreign* to the sphere of transcendental philosophy, not to +injure the unity of our system by digressions, nor, on the other hand, +to fail in clearness, by saying too little on the new subject of +discussion. I hope to avoid both extremes, by keeping as close as +possible to the transcendental, and excluding all psychological, +that is, empirical, elements. + +[*Footnote: All practical conceptions relate to objects of pleasure +and pain, and consequently--in an indirect manner, at least--to objects +of feeling. But as feeling is not a faculty of representation, but +lies out of the sphere of our powers of cognition, the elements of +our judgements, in so far as they relate to pleasure or pain, that +is, the elements of our practical judgements, do not belong to +transcendental philosophy, which has to do with pure a priori +cognitions alone.] + +I have to remark, in the first place, that at present I treat of the +conception of freedom in the practical sense only, and set aside the +corresponding transcendental conception, which cannot be employed as +a ground of explanation in the phenomenal world, but is itself a problem +for pure reason. A will is purely animal (arbitrium brutum) when it +is determined by sensuous impulses or instincts only, that is, when +it is determined in a pathological manner. A will, which can be determined +independently of sensuous impulses, consequently by motives +presented by reason alone, is called a free will (arbitrium +liberum); and everything which is connected with this free will, +either as principle or consequence, is termed practical. The existence +of practical freedom can be proved from experience alone. For the +human will is not determined by that alone which immediately affects +the senses; on the contrary, we have the power, by calling up the +notion of what is useful or hurtful in a more distant relation, of +overcoming the immediate impressions on our sensuous faculty of +desire. But these considerations of what is desirable in relation to +our whole state, that is, is in the end good and useful, are based +entirely upon reason. This faculty, accordingly, enounces laws, +which are imperative or objective laws of freedom and which tell us +what ought to take place, thus distinguishing themselves from the laws +of nature, which relate to that which does take place. The laws of +freedom or of free will are hence termed practical laws. + +Whether reason is not itself, in the actual delivery of these +laws, determined in its turn by other influences, and whether the +action which, in relation to sensuous impulses, we call free, may not, +in relation to higher and more remote operative causes, really form +a part of nature--these are questions which do not here concern us. +They are purely speculative questions; and all we have to do, in the +practical sphere, is to inquire into the rule of conduct which +reason has to present. Experience demonstrates to us the existence +of practical freedom as one of the causes which exist in nature, +that is, it shows the causal power of reason in the determination of +the will. The idea of transcendental freedom, on the contrary, +requires that reason--in relation to its causal power of commencing +a series of phenomena--should be independent of all sensuous +determining causes; and thus it seems to be in opposition to the law +of nature and to all possible experience. It therefore remains a +problem for the human mind. But this problem does not concern reason +in its practical use; and we have, therefore, in a canon of pure +reason, to do with only two questions, which relate to the practical +interest of pure reason: Is there a God? and, Is there a future +life? The question of transcendental freedom is purely speculative, +and we may therefore set it entirely aside when we come to treat of +practical reason. Besides, we have already discussed this subject in +the antinomy of pure reason. + + + +SECTION II. Of the Ideal of the Summum Bonum as a Determining + Ground of the Ultimate End of Pure Reason. + +Reason conducted us, in its speculative use, through the field of +experience and, as it can never find complete satisfaction in that +sphere, from thence to speculative ideas--which, however, in the end +brought us back again to experience, and thus fulfilled the purpose +of reason, in a manner which, though useful, was not at all in accordance +with our expectations. It now remains for us to consider whether +pure reason can be employed in a practical sphere, and whether it will +here conduct us to those ideas which attain the highest ends of pure +reason, as we have just stated them. We shall thus ascertain +whether, from the point of view of its practical interest, reason +may not be able to supply us with that which, on the speculative side, +it wholly denies us. + +The whole interest of reason, speculative as well as practical, is +centred in the three following questions: + + 1. WHAT CAN I KNOW? + 2. WHAT OUGHT I TO DO? + 3. WHAT MAY I HOPE? + +The first question is purely speculative. We have, as I flatter +myself, exhausted all the replies of which it is susceptible, and have +at last found the reply with which reason must content itself, and +with which it ought to be content, so long as it pays no regard to +the practical. But from the two great ends to the attainment of which +all these efforts of pure reason were in fact directed, we remain just +as far removed as if we had consulted our ease and declined the task +at the outset. So far, then, as knowledge is concerned, thus much, +at least, is established, that, in regard to those two problems, it +lies beyond our reach. + +The second question is purely practical. As such it may indeed +fall within the province of pure reason, but still it is not +transcendental, but moral, and consequently cannot in itself form +the subject of our criticism. + +The third question: If I act as I ought to do, what may I then +hope?--is at once practical and theoretical. The practical forms a +clue to the answer of the theoretical, and--in its highest form- +speculative question. For all hoping has happiness for its object +and stands in precisely the same relation to the practical and the +law of morality as knowing to the theoretical cognition of things and +the law of nature. The former arrives finally at the conclusion that +something is (which determines the ultimate end), because something +ought to take place; the latter, that something is (which operates +as the highest cause), because something does take place. + +Happiness is the satisfaction of all our desires; extensive, in +regard to their multiplicity; intensive, in regard to their degree; +and protensive, in regard to their duration. The practical law based +on the motive of happiness I term a pragmatical law (or prudential +rule); but that law, assuming such to exist, which has no other motive +than the worthiness of being happy, I term a moral or ethical law. +The first tells us what we have to do, if we wish to become possessed +of happiness; the second dictates how we ought to act, in order to +deserve happiness. The first is based upon empirical principles; for +it is only by experience that I can learn either what inclinations +exist which desire satisfaction, or what are the natural means of +satisfying them. The second takes no account of our desires or the +means of satisfying them, and regards only the freedom of a rational +being, and the necessary conditions under which alone this freedom +can harmonize with the distribution of happiness according to +principles. This second law may therefore rest upon mere ideas of pure +reason, and may be cognized a priori. + +I assume that there are pure moral laws which determine, entirely +a priori (without regard to empirical motives, that is, to happiness), +the conduct of a rational being, or in other words, to use which it +makes of its freedom, and that these laws are absolutely imperative +(not merely hypothetically, on the supposition of other empirical +ends), and therefore in all respects necessary. I am warranted in +assuming this, not only by the arguments of the most enlightened +moralists, but by the moral judgement of every man who will make the +attempt to form a distinct conception of such a law. + +Pure reason, then, contains, not indeed in its speculative, but in +its practical, or, more strictly, its moral use, principles of the +possibility of experience, of such actions, namely, as, in +accordance with ethical precepts, might be met with in the history +of man. For since reason commands that such actions should take place, +it must be possible for them to take place; and hence a particular +kind of systematic unity--the moral--must be possible. We have +found, it is true, that the systematic unity of nature could not be +established according to speculative principles of reason, because, +while reason possesses a causal power in relation to freedom, it has +none in relation to the whole sphere of nature; and, while moral +principles of reason can produce free actions, they cannot produce +natural laws. It is, then, in its practical, but especially in its +moral use, that the principles of pure reason possess objective +reality. + +I call the world a moral world, in so far as it may be in accordance +with all the ethical laws--which, by virtue of the freedom of +reasonable beings, it can be, and according to the necessary laws of +morality it ought to be. But this world must be conceived only as an +intelligible world, inasmuch as abstraction is therein made of all +conditions (ends), and even of all impediments to morality (the +weakness or pravity of human nature). So far, then, it is a mere idea- +though still a practical idea--which may have, and ought to have, an +influence on the world of sense, so as to bring it as far as +possible into conformity with itself. The idea of a moral world has, +therefore, objective reality, not as referring to an object of +intelligible intuition--for of such an object we can form no +conception whatever--but to the world of sense--conceived, however, +as an object of pure reason in its practical use--and to a corpus +mysticum of rational beings in it, in so far as the liberum +arbitrium of the individual is placed, under and by virtue of moral +laws, in complete systematic unity both with itself and with the +freedom of all others. + +That is the answer to the first of the two questions of pure +reason which relate to its practical interest: Do that which will +render thee worthy of happiness. The second question is this: If I +conduct myself so as not to be unworthy of happiness, may I hope +thereby to obtain happiness? In order to arrive at the solution of +this question, we must inquire whether the principles of pure +reason, which prescribe a priori the law, necessarily also connect +this hope with it. + +I say, then, that just as the moral principles are necessary +according to reason in its practical use, so it is equally necessary +according to reason in its theoretical use to assume that every one +has ground to hope for happiness in the measure in which he has made +himself worthy of it in his conduct, and that therefore the system +of morality is inseparably (though only in the idea of pure reason) +connected with that of happiness. + +Now in an intelligible, that is, in the moral world, in the +conception of which we make abstraction of all the impediments to +morality (sensuous desires), such a system of happiness, connected +with and proportioned to morality, may be conceived as necessary, +because freedom of volition--partly incited, and partly restrained +by moral laws--would be itself the cause of general happiness; and +thus rational beings, under the guidance of such principles, would +be themselves the authors both of their own enduring welfare and +that of others. But such a system of self-rewarding morality is only +an idea, the carrying out of which depends upon the condition that +every one acts as he ought; in other words, that all actions of +reasonable beings be such as they would be if they sprung from a +Supreme Will, comprehending in, or under, itself all particular wills. +But since the moral law is binding on each individual in the use of +his freedom of volition, even if others should not act in conformity +with this law, neither the nature of things, nor the causality of +actions and their relation to morality, determine how the consequences +of these actions will be related to happiness; and the necessary +connection of the hope of happiness with the unceasing endeavour to +become worthy of happiness, cannot be cognized by reason, if we take +nature alone for our guide. This connection can be hoped for only on +the assumption that the cause of nature is a supreme reason, which +governs according to moral laws. + +I term the idea of an intelligence in which the morally most perfect +will, united with supreme blessedness, is the cause of all happiness +in the world, so far as happiness stands in strict relation to +morality (as the worthiness of being happy), the ideal of the supreme +Good. It is only, then, in the ideal of the supreme original good, +that pure reason can find the ground of the practically necessary +connection of both elements of the highest derivative good, and +accordingly of an intelligible, that is, moral world. Now since we are +necessitated by reason to conceive ourselves as belonging to such a +world, while the senses present to us nothing but a world of +phenomena, we must assume the former as a consequence of our conduct +in the world of sense (since the world of sense gives us no hint of +it), and therefore as future in relation to us. Thus God and a future +life are two hypotheses which, according to the principles of pure +reason, are inseparable from the obligation which this reason imposes +upon us. + +Morality per se constitutes a system. But we can form no system of +happiness, except in so far as it is dispensed in strict proportion +to morality. But this is only possible in the intelligible world, under +a wise author and ruler. Such a ruler, together with life in such a +world, which we must look upon as future, reason finds itself +compelled to assume; or it must regard the moral laws as idle +dreams, since the necessary consequence which this same reason +connects with them must, without this hypothesis, fall to the +ground. Hence also the moral laws are universally regarded as +commands, which they could not be did they not connect a priori +adequate consequences with their dictates, and thus carry with them +promises and threats. But this, again, they could not do, did they +not reside in a necessary being, as the Supreme Good, which alone can +render such a teleological unity possible. + +Leibnitz termed the world, when viewed in relation to the rational +beings which it contains, and the moral relations in which they +stand to each other, under the government of the Supreme Good, the +kingdom of Grace, and distinguished it from the kingdom of Nature, +in which these rational beings live, under moral laws, indeed, but +expect no other consequences from their actions than such as follow +according to the course of nature in the world of sense. To view +ourselves, therefore, as in the kingdom of grace, in which all +happiness awaits us, except in so far as we ourselves limit our +participation in it by actions which render us unworthy of +happiness, is a practically necessary idea of reason. + +Practical laws, in so far as they are subjective grounds of actions, +that is, subjective principles, are termed maxims. The judgements of +moral according to in its purity and ultimate results are framed +according ideas; the observance of its laws, according to according +to maxims. + +The whole course of our life must be subject to moral maxims; but +this is impossible, unless with the moral law, which is a mere idea, +reason connects an efficient cause which ordains to all conduct +which is in conformity with the moral law an issue either in this or +in another life, which is in exact conformity with our highest aims. +Thus, without a God and without a world, invisible to us now, but +hoped for, the glorious ideas of morality are, indeed, objects of +approbation and of admiration, but cannot be the springs of purpose +and action. For they do not satisfy all the aims which are natural +to every rational being, and which are determined a priori by pure +reason itself, and necessary. + +Happiness alone is, in the view of reason, far from being the +complete good. Reason does not approve of it (however much inclination +may desire it), except as united with desert. On the other hand, +morality alone, and with it, mere desert, is likewise far from being +the complete good. To make it complete, he who conducts himself in +a manner not unworthy of happiness, must be able to hope for the +possession of happiness. Even reason, unbiased by private ends, or +interested considerations, cannot judge otherwise, if it puts itself +in the place of a being whose business it is to dispense all happiness +to others. For in the practical idea both points are essentially +combined, though in such a way that participation in happiness is +rendered possible by the moral disposition, as its condition, and +not conversely, the moral disposition by the prospect of happiness. +For a disposition which should require the prospect of happiness as +its necessary condition would not be moral, and hence also would not +be worthy of complete happiness--a happiness which, in the view of +reason, recognizes no limitation but such as arises from our own +immoral conduct. + +Happiness, therefore, in exact proportion with the morality of +rational beings (whereby they are made worthy of happiness), +constitutes alone the supreme good of a world into which we absolutely +must transport ourselves according to the commands of pure but +practical reason. This world is, it is true, only an intelligible +world; for of such a systematic unity of ends as it requires, the +world of sense gives us no hint. Its reality can be based on nothing +else but the hypothesis of a supreme original good. In it +independent reason, equipped with all the sufficiency of a supreme +cause, founds, maintains, and fulfils the universal order of things, +with the most perfect teleological harmony, however much this order +may be hidden from us in the world of sense. + +This moral theology has the peculiar advantage, in contrast with +speculative theology, of leading inevitably to the conception of a +sole, perfect, and rational First Cause, whereof speculative +theology does not give us any indication on objective grounds, far +less any convincing evidence. For we find neither in transcendental +nor in natural theology, however far reason may lead us in these, +any ground to warrant us in assuming the existence of one only +Being, which stands at the head of all natural causes, and on which +these are entirely dependent. On the other band, if we take our +stand on moral unity as a necessary law of the universe, and from this +point of view consider what is necessary to give this law adequate +efficiency and, for us, obligatory force, we must come to the +conclusion that there is one only supreme will, which comprehends +all these laws in itself. For how, under different wills, should we +find complete unity of ends? This will must be omnipotent, that all +nature and its relation to morality in the world may be subject to +it; omniscient, that it may have knowledge of the most secret feelings +and their moral worth; omnipresent, that it may be at hand to supply +every necessity to which the highest weal of the world may give rise; +eternal, that this harmony of nature and liberty may never fail; and +so on. + +But this systematic unity of ends in this world of intelligences- +which, as mere nature, is only a world of sense, but, as a system of +freedom of volition, may be termed an intelligible, that is, moral +world (regnum gratiae)--leads inevitably also to the teleological +unity of all things which constitute this great whole, according to +universal natural laws--just as the unity of the former is according +to universal and necessary moral laws--and unites the practical with +the speculative reason. The world must be represented as having +originated from an idea, if it is to harmonize with that use of reason +without which we cannot even consider ourselves as worthy of reason- +namely, the moral use, which rests entirely on the idea of the supreme +good. Hence the investigation of nature receives a teleological +direction, and becomes, in its widest extension, physico-theology. +But this, taking its rise in moral order as a unity founded on the +essence of freedom, and not accidentally instituted by external commands, +establishes the teleological view of nature on grounds which must be +inseparably connected with the internal possibility of things. This +gives rise to a transcendental theology, which takes the ideal of +the highest ontological perfection as a principle of systematic unity; +and this principle connects all things according to universal and +necessary natural laws, because all things have their origin in the +absolute necessity of the one only Primal Being. + +What use can we make of our understanding, even in respect of +experience, if we do not propose ends to ourselves? But the highest +ends are those of morality, and it is only pure reason that can give +us the knowledge of these. Though supplied with these, and putting +ourselves under their guidance, we can make no teleological use of +the knowledge of nature, as regards cognition, unless nature itself +has established teleological unity. For without this unity we should +not even possess reason, because we should have no school for reason, +and no cultivation through objects which afford the materials for +its conceptions. But teleological unity is a necessary unity, and +founded on the essence of the individual will itself. Hence this will, +which is the condition of the application of this unity in concreto, +must be so likewise. In this way the transcendental enlargement of +our rational cognition would be, not the cause, but merely the effect +of the practical teleology which pure reason imposes upon us. + +Hence, also, we find in the history of human reason that, before the +moral conceptions were sufficiently purified and determined, and +before men had attained to a perception of the systematic unity of +ends according to these conceptions and from necessary principles, +the knowledge of nature, and even a considerable amount of intellectual +culture in many other sciences, could produce only rude and vague +conceptions of the Deity, sometimes even admitting of an astonishing +indifference with regard to this question altogether. But the more +enlarged treatment of moral ideas, which was rendered necessary by +the extreme pure moral law of our religion, awakened the interest, +and thereby quickened the perceptions of reason in relation to this +object. In this way, and without the help either of an extended +acquaintance with nature, or of a reliable transcendental insight (for +these have been wanting in all ages), a conception of the Divine Being +was arrived at, which we now bold to be the correct one, not because +speculative reason convinces us of its correctness, but because it +accords with the moral principles of reason. Thus it is to pure +reason, but only in its practical use, that we must ascribe the +merit of having connected with our highest interest a cognition, of +which mere speculation was able only to form a conjecture, but the +validity of which it was unable to establish--and of having thereby +rendered it, not indeed a demonstrated dogma, but a hypothesis +absolutely necessary to the essential ends of reason. + +But if practical reason has reached this elevation, and has attained +to the conception of a sole Primal Being as the supreme good, it +must not, therefore, imagine that it has transcended the empirical +conditions of its application, and risen to the immediate cognition +of new objects; it must not presume to start from the conception which +it has gained, and to deduce from it the moral laws themselves. For +it was these very laws, the internal practical necessity of which led +us to the hypothesis of an independent cause, or of a wise ruler of +the universe, who should give them effect. Hence we are not entitled +to regard them as accidental and derived from the mere will of the +ruler, especially as we have no conception of such a will, except as +formed in accordance with these laws. So far, then, as practical +reason has the right to conduct us, we shall not look upon actions +as binding on us, because they are the commands of God, but we shall +regard them as divine commands, because we are internally bound by +them. We shall study freedom under the teleological unity which +accords with principles of reason; we shall look upon ourselves as +acting in conformity with the divine will only in so far as we hold +sacred the moral law which reason teaches us from the nature of +actions themselves, and we shall believe that we can obey that will +only by promoting the weal of the universe in ourselves and in others. +Moral theology is, therefore, only of immanent use. It teaches us to +fulfil our destiny here in the world, by placing ourselves in +harmony with the general system of ends, and warns us against the +fanaticism, nay, the crime of depriving reason of its legislative +authority in the moral conduct of life, for the purpose of directly +connecting this authority with the idea of the Supreme Being. For this +would be, not an immanent, but a transcendent use of moral theology, +and, like the transcendent use of mere speculation, would inevitably +pervert and frustrate the ultimate ends of reason. + + + +SECTION III. Of Opinion, Knowledge, and Belief. + +The holding of a thing to be true is a phenomenon in our +understanding which may rest on objective grounds, but requires, also, +subjective causes in the mind of the person judging. If a judgement +is valid for every rational being, then its ground is objectively +sufficient, and it is termed a conviction. If, on the other hand, it +has its ground in the particular character of the subject, it is +termed a persuasion. + +Persuasion is a mere illusion, the ground of the judgement, which +lies solely in the subject, being regarded as objective. Hence a +judgement of this kind has only private validity--is only valid for +the individual who judges, and the holding of a thing to be true in +this way cannot be communicated. But truth depends upon agreement with +the object, and consequently the judgements of all understandings, +if true, must be in agreement with each other (consentientia uni +tertio consentiunt inter se). Conviction may, therefore, be +distinguished, from an external point of view, from persuasion, by +the possibility of communicating it and by showing its validity for +the reason of every man; for in this case the presumption, at least, +arises that the agreement of all judgements with each other, in +spite of the different characters of individuals, rests upon the +common ground of the agreement of each with the object, and thus the +correctness of the judgement is established. + +Persuasion, accordingly, cannot be subjectively distinguished from +conviction, that is, so long as the subject views its judgement simply +as a phenomenon of its own mind. But if we inquire whether the grounds +of our judgement, which are valid for us, produce the same effect on +the reason of others as on our own, we have then the means, though +only subjective means, not, indeed, of producing conviction, but of +detecting the merely private validity of the judgement; in other +words, of discovering that there is in it the element of mere +persuasion. + +If we can, in addition to this, develop the subjective causes of the +judgement, which we have taken for its objective grounds, and thus +explain the deceptive judgement as a phenomenon in our mind, apart +altogether from the objective character of the object, we can then +expose the illusion and need be no longer deceived by it, although, +if its subjective cause lies in our nature, we cannot hope altogether +to escape its influence. + +I can only maintain, that is, affirm as necessarily valid for +every one, that which produces conviction. Persuasion I may keep for +myself, if it is agreeable to me; but I cannot, and ought not, to +attempt to impose it as binding upon others. + +Holding for true, or the subjective validity of a judgement in +relation to conviction (which is, at the same time, objectively +valid), has the three following degrees: opinion, belief, and +knowledge. Opinion is a consciously insufficient judgement, +subjectively as well as objectively. Belief is subjectively +sufficient, but is recognized as being objectively insufficient. +Knowledge is both subjectively and objectively sufficient. +Subjective sufficiency is termed conviction (for myself); objective +sufficiency is termed certainty (for all). I need not dwell longer +on the explanation of such simple conceptions. + +I must never venture to be of opinion, without knowing something, at +least, by which my judgement, in itself merely problematical, is +brought into connection with the truth--which connection, although +not perfect, is still something more than an arbitrary fiction. +Moreover, the law of such a connection must be certain. For if, in +relation to this law, I have nothing more than opinion, my judgement +is but a play of the imagination, without the least relation to truth. +In the judgements of pure reason, opinion has no place. For, as they +do not rest on empirical grounds and as the sphere of pure reason is +that of necessary truth and a priori cognition, the principle of +connection in it requires universality and necessity, and consequently +perfect certainty--otherwise we should have no guide to the truth at +all. Hence it is absurd to have an opinion in pure mathematics; we +must know, or abstain from forming a judgement altogether. The case +is the same with the maxims of morality. For we must not hazard an +action on the mere opinion that it is allowed, but we must know it +to be so. In the transcendental sphere of reason, on the other hand, +the term opinion is too weak, while the word knowledge is too strong. +From the merely speculative point of view, therefore, we cannot form +a judgement at all. For the subjective grounds of a judgement, such +as produce belief, cannot be admitted in speculative inquiries, +inasmuch as they cannot stand without empirical support and are +incapable of being communicated to others in equal measure. + +But it is only from the practical point of view that a theoretically +insufficient judgement can be termed belief. Now the practical +reference is either to skill or to morality; to the former, when the +end proposed is arbitrary and accidental, to the latter, when it is +absolutely necessary. + +If we propose to ourselves any end whatever, the conditions of its +attainment are hypothetically necessary. The necessity is +subjectively, but still only comparatively, sufficient, if I am +acquainted with no other conditions under which the end can be +attained. On the other hand, it is sufficient, absolutely and for +every one, if I know for certain that no one can be acquainted with +any other conditions under which the attainment of the proposed end +would be possible. In the former case my supposition--my judgement +with regard to certain conditions--is a merely accidental belief; in +the latter it is a necessary belief. The physician must pursue some +course in the case of a patient who is in danger, but is ignorant of +the nature of the disease. He observes the symptoms, and concludes, +according to the best of his judgement, that it is a case of phthisis. +His belief is, even in his own judgement, only contingent: another +man might, perhaps come nearer the truth. Such a belief, contingent +indeed, but still forming the ground of the actual use of means for +the attainment of certain ends, I term Pragmatical belief. + +The usual test, whether that which any one maintains is merely his +persuasion, or his subjective conviction at least, that is, his firm +belief, is a bet. It frequently happens that a man delivers his +opinions with so much boldness and assurance, that he appears to be +under no apprehension as to the possibility of his being in error. +The offer of a bet startles him, and makes him pause. Sometimes it +turns out that his persuasion may be valued at a ducat, but not at +ten. For he does not hesitate, perhaps, to venture a ducat, but if +it is proposed to stake ten, he immediately becomes aware of the +possibility of his being mistaken--a possibility which has hitherto +escaped his observation. If we imagine to ourselves that we have to +stake the happiness of our whole life on the truth of any proposition, +our judgement drops its air of triumph, we take the alarm, and discover +the actual strength of our belief. Thus pragmatical belief has +degrees, varying in proportion to the interests at stake. + +Now, in cases where we cannot enter upon any course of action in +reference to some object, and where, accordingly, our judgement is +purely theoretical, we can still represent to ourselves, in thought, +the possibility of a course of action, for which we suppose that we +have sufficient grounds, if any means existed of ascertaining the +truth of the matter. Thus we find in purely theoretical judgements +an analogon of practical judgements, to which the word belief may +properly be applied, and which we may term doctrinal belief. I +should not hesitate to stake my all on the truth of the proposition- +if there were any possibility of bringing it to the test of +experience--that, at least, some one of the planets, which we see, +is inhabited. Hence I say that I have not merely the opinion, but +the strong belief, on the correctness of which I would stake even many +of the advantages of life, that there are inhabitants in other worlds. + +Now we must admit that the doctrine of the existence of God +belongs to doctrinal belief. For, although in respect to the +theoretical cognition of the universe I do not require to form any +theory which necessarily involves this idea, as the condition of my +explanation of the phenomena which the universe presents, but, on +the contrary, am rather bound so to use my reason as if everything +were mere nature, still teleological unity is so important a condition +of the application of my reason to nature, that it is impossible for +me to ignore it--especially since, in addition to these +considerations, abundant examples of it are supplied by experience. +But the sole condition, so far as my knowledge extends, under which +this unity can be my guide in the investigation of nature, is the +assumption that a supreme intelligence has ordered all things +according to the wisest ends. Consequently, the hypothesis of a wise +author of the universe is necessary for my guidance in the +investigation of nature--is the condition under which alone I can +fulfil an end which is contingent indeed, but by no means unimportant. +Moreover, since the result of my attempts so frequently confirms the +utility of this assumption, and since nothing decisive can be +adduced against it, it follows that it would be saying far too +little to term my judgement, in this case, a mere opinion, and that, +even in this theoretical connection, I may assert that I firmly +believe in God. Still, if we use words strictly, this must not be +called a practical, but a doctrinal belief, which the theology of +nature (physico-theology) must also produce in my mind. In the +wisdom of a Supreme Being, and in the shortness of life, so inadequate +to the development of the glorious powers of human nature, we may find +equally sufficient grounds for a doctrinal belief in the future life +of the human soul. + +The expression of belief is, in such cases, an expression of modesty +from the objective point of view, but, at the same time, of firm +confidence, from the subjective. If I should venture to term this +merely theoretical judgement even so much as a hypothesis which I am +entitled to assume; a more complete conception, with regard to another +world and to the cause of the world, might then be justly required +of me than I am, in reality, able to give. For, if I assume +anything, even as a mere hypothesis, I must, at least, know so much +of the properties of such a being as will enable me, not to form the +conception, but to imagine the existence of it. But the word belief +refers only to the guidance which an idea gives me, and to its +subjective influence on the conduct of my reason, which forces me to +hold it fast, though I may not be in a position to give a +speculative account of it. + +But mere doctrinal belief is, to some extent, wanting in +stability. We often quit our hold of it, in consequence of the +difficulties which occur in speculation, though in the end we +inevitably return to it again. + +It is quite otherwise with moral belief. For in this sphere action +is absolutely necessary, that is, I must act in obedience to the moral +law in all points. The end is here incontrovertibly established, and +there is only one condition possible, according to the best of my +perception, under which this end can harmonize with all other ends, +and so have practical validity--namely, the existence of a God and +of a future world. I know also, to a certainty, that no one can be +acquainted with any other conditions which conduct to the same unity +of ends under the moral law. But since the moral precept is, at the +same time, my maxim (as reason requires that it should be), I am +irresistibly constrained to believe in the existence of God and in +a future life; and I am sure that nothing can make me waver in this +belief, since I should thereby overthrow my moral maxims, the +renunciation of which would render me hateful in my own eyes. + +Thus, while all the ambitious attempts of reason to penetrate beyond +the limits of experience end in disappointment, there is still +enough left to satisfy us in a practical point of view. No one, it +is true, will be able to boast that he knows that there is a God and +a future life; for, if he knows this, he is just the man whom I have +long wished to find. All knowledge, regarding an object of mere +reason, can be communicated; and I should thus be enabled to hope that +my own knowledge would receive this wonderful extension, through the +instrumentality of his instruction. No, my conviction is not +logical, but moral certainty; and since it rests on subjective grounds +(of the moral sentiment), I must not even say: It is morally certain +that there is a God, etc., but: I am morally certain, that is, my +belief in God and in another world is so interwoven with my moral +nature that I am under as little apprehension of having the former +torn from me as of losing the latter. + +The only point in this argument that may appear open to suspicion is +that this rational belief presupposes the existence of moral +sentiments. If we give up this assumption, and take a man who is +entirely indifferent with regard to moral laws, the question which +reason proposes, becomes then merely a problem for speculation and +may, indeed, be supported by strong grounds from analogy, but not by +such as will compel the most obstinate scepticism to give way.* But +in these questions no man is free from all interest. For though the +want of good sentiments may place him beyond the influence of moral +interests, still even in this case enough may be left to make him fear +the existence of God and a future life. For he cannot pretend to any +certainty of the non-existence of God and of a future life, unless- +since it could only be proved by mere reason, and therefore +apodeictically--he is prepared to establish the impossibility of both, +which certainly no reasonable man would undertake to do. This would +be a negative belief, which could not, indeed, produce morality and +good sentiments, but still could produce an analogon of these, by +operating as a powerful restraint on the outbreak of evil +dispositions. + +[*Footnote: The human mind (as, I believe, every rational being must +of necessity do) takes a natural interest in morality, although this +interest is not undivided, and may not be practically in +preponderance. If you strengthen and increase it, you will find the +reason become docile, more enlightened, and more capable of uniting +the speculative interest with the practical. But if you do not take +care at the outset, or at least midway, to make men good, you will +never force them into an honest belief.] + +But, it will be said, is this all that pure reason can effect, in +opening up prospects beyond the limits of experience? Nothing more +than two articles of belief? Common sense could have done as much as +this, without taking the philosophers to counsel in the matter! + +I shall not here eulogize philosophy for the benefits which the +laborious efforts of its criticism have conferred on human reason- +even granting that its merit should turn out in the end to be only +negative--for on this point something more will be said in the next +section. But, I ask, do you require that that knowledge which concerns +all men, should transcend the common understanding, and should only +be revealed to you by philosophers? The very circumstance which has +called forth your censure, is the best confirmation of the correctness +of our previous assertions, since it discloses, what could not have +been foreseen, that Nature is not chargeable with any partial +distribution of her gifts in those matters which concern all men +without distinction and that, in respect to the essential ends of +human nature, we cannot advance further with the help of the highest +philosophy, than under the guidance which nature has vouchsafed to +the meanest understanding. + + + +CHAPTER III. The Architectonic of Pure Reason. + +By the term architectonic I mean the art of constructing a system. +Without systematic unity, our knowledge cannot become science; it will +be an aggregate, and not a system. Thus architectonic is the +doctrine of the scientific in cognition, and therefore necessarily +forms part of our methodology. + +Reason cannot permit our knowledge to remain in an unconnected and +rhapsodistic state, but requires that the sum of our cognitions should +constitute a system. It is thus alone that they can advance the ends +of reason. By a system I mean the unity of various cognitions under +one idea. This idea is the conception--given by reason--of the form +of a whole, in so far as the conception determines a priori not only +the limits of its content, but the place which each of its parts is +to occupy. The scientific idea contains, therefore, the end and the +form of the whole which is in accordance with that end. The unity of +the end, to which all the parts of the system relate, and through +which all have a relation to each other, communicates unity to the +whole system, so that the absence of any part can be immediately +detected from our knowledge of the rest; and it determines a priori +the limits of the system, thus excluding all contingent or arbitrary +additions. The whole is thus an organism (articulatio), and not an +aggregate (coacervatio); it may grow from within (per +intussusceptionem), but it cannot increase by external additions +(per appositionem). It is, thus, like an animal body, the growth of +which does not add any limb, but, without changing their +proportions, makes each in its sphere stronger and more active. + +We require, for the execution of the idea of a system, a schema, +that is, a content and an arrangement of parts determined a priori +by the principle which the aim of the system prescribes. A schema +which is not projected in accordance with an idea, that is, from the +standpoint of the highest aim of reason, but merely empirically, in +accordance with accidental aims and purposes (the number of which +cannot be predetermined), can give us nothing more than technical +unity. But the schema which is originated from an idea (in which +case reason presents us with aims a priori, and does not look for them +to experience), forms the basis of architectonical unity. A science, +in the proper acceptation of that term, cannot be formed +technically, that is, from observation of the similarity existing +between different objects, and the purely contingent use we make of +our knowledge in concreto with reference to all kinds of arbitrary +external aims; its constitution must be framed on architectonical +principles, that is, its parts must be shown to possess an essential +affinity, and be capable of being deduced from one supreme and +internal aim or end, which forms the condition of the possibility of +the scientific whole. The schema of a science must give a priori the +plan of it (monogramma), and the division of the whole into parts, +in conformity with the idea of the science; and it must also +distinguish this whole from all others, according to certain +understood principles. + +No one will attempt to construct a science, unless he have some idea +to rest on as a proper basis. But, in the elaboration of the +science, he finds that the schema, nay, even the definition which he +at first gave of the science, rarely corresponds with his idea; for +this idea lies, like a germ, in our reason, its parts undeveloped +and hid even from microscopical observation. For this reason, we ought +to explain and define sciences, not according to the description which +the originator gives of them, but according to the idea which we +find based in reason itself, and which is suggested by the natural +unity of the parts of the science already accumulated. For it will +of ten be found that the originator of a science and even his latest +successors remain attached to an erroneous idea, which they cannot +render clear to themselves, and that they thus fail in determining +the true content, the articulation or systematic unity, and the limits +of their science. + +It is unfortunate that, only after having occupied ourselves for a +long time in the collection of materials, under the guidance of an +idea which lies undeveloped in the mind, but not according to any +definite plan of arrangement--nay, only after we have spent much +time and labour in the technical disposition of our materials, does +it become possible to view the idea of a science in a clear light, +and to project, according to architectonical principles, a plan of +the whole, in accordance with the aims of reason. Systems seem, like +certain worms, to be formed by a kind of generatio aequivoca--by the +mere confluence of conceptions, and to gain completeness only with +the progress of time. But the schema or germ of all lies in reason; +and thus is not only every system organized according to its own idea, +but all are united into one grand system of human knowledge, of which +they form members. For this reason, it is possible to frame an +architectonic of all human cognition, the formation of which, at the +present time, considering the immense materials collected or to be +found in the ruins of old systems, would not indeed be very difficult. +Our purpose at present is merely to sketch the plan of the +architectonic of all cognition given by pure reason; and we begin from +the point where the main root of human knowledge divides into two, +one of which is reason. By reason I understand here the whole higher +faculty of cognition, the rational being placed in contradistinction +to the empirical. + +If I make complete abstraction of the content of cognition, +objectively considered, all cognition is, from a subjective point of +view, either historical or rational. Historical cognition is +cognitio ex datis, rational, cognitio ex principiis. Whatever may be +the original source of a cognition, it is, in relation to the person +who possesses it, merely historical, if he knows only what has been +given him from another quarter, whether that knowledge was +communicated by direct experience or by instruction. Thus the Person +who has learned a system of philosophy--say the Wolfian--although he +has a perfect knowledge of all the principles, definitions, and +arguments in that philosophy, as well as of the divisions that have +been made of the system, possesses really no more than an historical +knowledge of the Wolfian system; he knows only what has been told him, +his judgements are only those which he has received from his teachers. +Dispute the validity of a definition, and he is completely at a loss +to find another. He has formed his mind on another's; but the +imitative faculty is not the productive. His knowledge has not been +drawn from reason; and although, objectively considered, it is +rational knowledge, subjectively, it is merely historical. He has +learned this or that philosophy and is merely a plaster cast of a +living man. Rational cognitions which are objective, that is, which +have their source in reason, can be so termed from a subjective +point of view, only when they have been drawn by the individual +himself from the sources of reason, that is, from principles; and it +is in this way alone that criticism, or even the rejection of what +has been already learned, can spring up in the mind. + +All rational cognition is, again, based either on conceptions, or on +the construction of conceptions. The former is termed philosophical, +the latter mathematical. I have already shown the essential difference +of these two methods of cognition in the first chapter. A cognition +may be objectively philosophical and subjectively historical--as is +the case with the majority of scholars and those who cannot look +beyond the limits of their system, and who remain in a state of +pupilage all their lives. But it is remarkable that mathematical +knowledge, when committed to memory, is valid, from the subjective +point of view, as rational knowledge also, and that the same +distinction cannot be drawn here as in the case of philosophical +cognition. The reason is that the only way of arriving at this +knowledge is through the essential principles of reason, and thus it +is always certain and indisputable; because reason is employed in +concreto--but at the same time a priori--that is, in pure and, +therefore, infallible intuition; and thus all causes of illusion and +error are excluded. Of all the a priori sciences of reason, therefore, +mathematics alone can be learned. Philosophy--unless it be in an +historical manner--cannot be learned; we can at most learn to +philosophize. + +Philosophy is the system of all philosophical cognition. We must use +this term in an objective sense, if we understand by it the archetype +of all attempts at philosophizing, and the standard by which all +subjective philosophies are to be judged. In this sense, philosophy is +merely the idea of a possible science, which does not exist in +concreto, but to which we endeavour in various ways to approximate, +until we have discovered the right path to pursue--a path overgrown by +the errors and illusions of sense--and the image we have hitherto tried +in vain to shape has become a perfect copy of the great prototype. +Until that time, we cannot learn philosophy--it does not exist; if it +does, where is it, who possesses it, and how shall we know it? We can +only learn to philosophize; in other words, we can only exercise our +powers of reasoning in accordance with general principles, retaining at +the same time, the right of investigating the sources of these +principles, of testing, and even of rejecting them. + +Until then, our conception of philosophy is only a scholastic +conception--a conception, that is, of a system of cognition which we +are trying to elaborate into a science; all that we at present know +being the systematic unity of this cognition, and consequently the +logical completeness of the cognition for the desired end. But there +is also a cosmical conception (conceptus cosmicus) of philosophy, +which has always formed the true basis of this term, especially when +philosophy was personified and presented to us in the ideal of a +philosopher. In this view philosophy is the science of the relation +of all cognition to the ultimate and essential aims of human reason +(teleologia rationis humanae), and the philosopher is not merely an +artist--who occupies himself with conceptions--but a lawgiver, +legislating for human reason. In this sense of the word, it would be +in the highest degree arrogant to assume the title of philosopher, +and to pretend that we had reached the perfection of the prototype +which lies in the idea alone. + +The mathematician, the natural philosopher, and the logician--how +far soever the first may have advanced in rational, and the two latter +in philosophical knowledge--are merely artists, engaged in the +arrangement and formation of conceptions; they cannot be termed +philosophers. Above them all, there is the ideal teacher, who +employs them as instruments for the advancement of the essential +aims of human reason. Him alone can we call philosopher; but he +nowhere exists. But the idea of his legislative power resides in the +mind of every man, and it alone teaches us what kind of systematic +unity philosophy demands in view of the ultimate aims of reason. +This idea is, therefore, a cosmical conception.* + +[*Footnote: By a cosmical conception, I mean one in which all men +necessarily take an interest; the aim of a science must accordingly +be determined according to scholastic conceptions, if it is regarded +merely as a means to certain arbitrarily proposed ends.] + +In view of the complete systematic unity of reason, there can only +be one ultimate end of all the operations of the mind. To this all +other aims are subordinate, and nothing more than means for its +attainment. This ultimate end is the destination of man, and the +philosophy which relates to it is termed moral philosophy. The +superior position occupied by moral philosophy, above all other +spheres for the operations of reason, sufficiently indicates the +reason why the ancients always included the idea--and in an especial +manner--of moralist in that of philosopher. Even at the present day, +we call a man who appears to have the power of self-government, even +although his knowledge may be very limited, by the name of +philosopher. + +The legislation of human reason, or philosophy, has two objects- +nature and freedom--and thus contains not only the laws of nature, +but also those of ethics, at first in two separate systems, which, +finally, merge into one grand philosophical system of cognition. The +philosophy of nature relates to that which is, that of ethics to +that which ought to be. + +But all philosophy is either cognition on the basis of pure +reason, or the cognition of reason on the basis of empirical +principles. The former is termed pure, the latter empirical +philosophy. + +The philosophy of pure reason is either propaedeutic, that is, an +inquiry into the powers of reason in regard to pure a priori +cognition, and is termed critical philosophy; or it is, secondly, +the system of pure reason--a science containing the systematic +presentation of the whole body of philosophical knowledge, true as +well as illusory, given by pure reason--and is called metaphysic. This +name may, however, be also given to the whole system of pure +philosophy, critical philosophy included, and may designate the +investigation into the sources or possibility of a priori cognition, +as well as the presentation of the a priori cognitions which form a +system of pure philosophy--excluding, at the same time, all +empirical and mathematical elements. + +Metaphysic is divided into that of the speculative and that of the +practical use of pure reason, and is, accordingly, either the +metaphysic of nature, or the metaphysic of ethics. The former contains +all the pure rational principles--based upon conceptions alone (and +thus excluding mathematics)--of all theoretical cognition; the latter, +the principles which determine and necessitate a priori all action. +Now moral philosophy alone contains a code of laws--for the regulation +of our actions--which are deduced from principles entirely a priori. +Hence the metaphysic of ethics is the only pure moral philosophy, as +it is not based upon anthropological or other empirical +considerations. The metaphysic of speculative reason is what is +commonly called metaphysic in the more limited sense. But as pure +moral philosophy properly forms a part of this system of cognition, +we must allow it to retain the name of metaphysic, although it is not +requisite that we should insist on so terming it in our present +discussion. + +It is of the highest importance to separate those cognitions which +differ from others both in kind and in origin, and to take great +care that they are not confounded with those with which they are +generally found connected. What the chemist does in the analysis of +substances, what the mathematician in pure mathematics, is, in a still +higher degree, the duty of the philosopher, that the value of each +different kind of cognition, and the part it takes in the operations +of the mind, may be clearly defined. Human reason has never wanted +a metaphysic of some kind, since it attained the power of thought, +or rather of reflection; but it has never been able to keep this sphere +of thought and cognition pure from all admixture of foreign +elements. The idea of a science of this kind is as old as +speculation itself; and what mind does not speculate--either in the +scholastic or in the popular fashion? At the same time, it must be +admitted that even thinkers by profession have been unable clearly +to explain the distinction between the two elements of our +cognition--the one completely a priori, the other a posteriori; and +hence the proper definition of a peculiar kind of cognition, and +with it the just idea of a science which has so long and so deeply +engaged the attention of the human mind, has never been established. +When it was said: "Metaphysic is the science of the first principles +of human cognition," this definition did not signalize a peculiarity +in kind, but only a difference in degree; these first principles +were thus declared to be more general than others, but no criterion +of distinction from empirical principles was given. Of these some are +more general, and therefore higher, than others; and--as we cannot +distinguish what is completely a priori from that which is known to +be a posteriori--where shall we draw the line which is to separate +the higher and so-called first principles, from the lower and +subordinate principles of cognition? What would be said if we were +asked to be satisfied with a division of the epochs of the world +into the earlier centuries and those following them? "Does the +fifth, or the tenth century belong to the earlier centuries?" it would +be asked. In the same way I ask: Does the conception of extension +belong to metaphysics? You answer, "Yes." Well, that of body too? +"Yes." And that of a fluid body? You stop, you are unprepared to admit +this; for if you do, everything will belong to metaphysics. From +this it is evident that the mere degree of subordination--of the +particular to the general--cannot determine the limits of a science; +and that, in the present case, we must expect to find a difference +in the conceptions of metaphysics both in kind and in origin. The +fundamental idea of metaphysics was obscured on another side by the +fact that this kind of a priori cognition showed a certain +similarity in character with the science of mathematics. Both have +the property in common of possessing an a priori origin; but, in the +one, our knowledge is based upon conceptions, in the other, on the +construction of conceptions. Thus a decided dissimilarity between +philosophical and mathematical cognition comes out--a dissimilarity +which was always felt, but which could not be made distinct for want +of an insight into the criteria of the difference. And thus it +happened that, as philosophers themselves failed in the proper +development of the idea of their science, the elaboration of the +science could not proceed with a definite aim, or under trustworthy +guidance. Thus, too, philosophers, ignorant of the path they ought +to pursue and always disputing with each other regarding the +discoveries which each asserted he had made, brought their science +into disrepute with the rest of the world, and finally, even among +themselves. + +All pure a priori cognition forms, therefore, in view of the +peculiar faculty which originates it, a peculiar and distinct unity; +and metaphysic is the term applied to the philosophy which attempts +to represent that cognition in this systematic unity. The speculative +part of metaphysic, which has especially appropriated this +appellation--that which we have called the metaphysic of nature--and +which considers everything, as it is (not as it ought to be), by means +of a priori conceptions, is divided in the following manner. + +Metaphysic, in the more limited acceptation of the term, consists of +two parts--transcendental philosophy and the physiology of pure +reason. The former presents the system of all the conceptions and +principles belonging to the understanding and the reason, and which +relate to objects in general, but not to any particular given +objects (Ontologia); the latter has nature for its subject-matter, +that is, the sum of given objects--whether given to the senses, or, +if we will, to some other kind of intuition--and is accordingly +physiology, although only rationalis. But the use of the faculty of +reason in this rational mode of regarding nature is either physical +or hyperphysical, or, more properly speaking, immanent or transcendent. +The former relates to nature, in so far as our knowledge regarding +it may be applied in experience (in concreto); the latter to that +connection of the objects of experience, which transcends all +experience. Transcendent physiology has, again, an internal and an +external connection with its object, both, however, transcending +possible experience; the former is the physiology of nature as a +whole, or transcendental cognition of the world, the latter of the +connection of the whole of nature with a being above nature, or +transcendental cognition of God. + +Immanent physiology, on the contrary, considers nature as the sum of +all sensuous objects, consequently, as it is presented to us--but +still according to a priori conditions, for it is under these alone +that nature can be presented to our minds at all. The objects of +immanent physiology are of two kinds: 1. Those of the external senses, +or corporeal nature; 2. The object of the internal sense, the soul, +or, in accordance with our fundamental conceptions of it, thinking +nature. The metaphysics of corporeal nature is called physics; but, +as it must contain only the principles of an a priori cognition of +nature, we must term it rational physics. The metaphysics of +thinking nature is called psychology, and for the same reason is to +be regarded as merely the rational cognition of the soul. + +Thus the whole system of metaphysics consists of four principal +parts: 1. Ontology; 2. Rational Physiology; 3. Rational cosmology; +and 4. Rational theology. The second part--that of the rational doctrine +of nature--may be subdivided into two, physica rationalis* and +psychologia rationalis. + +[*Footnote: It must not be supposed that I mean by this appellation +what is generally called physica general is, and which is rather +mathematics than a philosophy of nature. For the metaphysic of nature +is completely different from mathematics, nor is it so rich in results, +although it is of great importance as a critical test of the +application of pure understanding-cognition to nature. For want of +its guidance, even mathematicians, adopting certain common notions- +which are, in fact, metaphysical--have unconsciously crowded their +theories of nature with hypotheses, the fallacy of which becomes +evident upon the application of the principles of this metaphysic, +without detriment, however, to the employment of mathematics in this +sphere of cognition.] + +The fundamental idea of a philosophy of pure reason of necessity +dictates this division; it is, therefore, architectonical--in +accordance with the highest aims of reason, and not merely +technical, or according to certain accidentally-observed +similarities existing between the different parts of the whole +science. For this reason, also, is the division immutable and of +legislative authority. But the reader may observe in it a few points +to which he ought to demur, and which may weaken his conviction of +its truth and legitimacy. + +In the first place, how can I desire an a priori cognition or +metaphysic of objects, in so far as they are given a posteriori? and +how is it possible to cognize the nature of things according to a +priori principles, and to attain to a rational physiology? The +answer is this. We take from experience nothing more than is requisite +to present us with an object (in general) of the external or of the +internal sense; in the former case, by the mere conception of matter +(impenetrable and inanimate extension), in the latter, by the +conception of a thinking being--given in the internal empirical +representation, I think. As to the rest, we must not employ in our +metaphysic of these objects any empirical principles (which add to +the content of our conceptions by means of experience), for the purpose +of forming by their help any judgements respecting these objects. + +Secondly, what place shall we assign to empirical psychology, +which has always been considered a part of metaphysics, and from which +in our time such important philosophical results have been expected, +after the hope of constructing an a priori system of knowledge had +been abandoned? I answer: It must be placed by the side of empirical +physics or physics proper; that is, must be regarded as forming a part +of applied philosophy, the a priori principles of which are +contained in pure philosophy, which is therefore connected, although +it must not be confounded, with psychology. Empirical psychology +must therefore be banished from the sphere of metaphysics, and is +indeed excluded by the very idea of that science. In conformity, +however, with scholastic usage, we must permit it to occupy a place +in metaphysics--but only as an appendix to it. We adopt this course +from motives of economy; as psychology is not as yet full enough to +occupy our attention as an independent study, while it is, at the same +time, of too great importance to be entirely excluded or placed +where it has still less affinity than it has with the subject of +metaphysics. It is a stranger who has been long a guest; and we make +it welcome to stay, until it can take up a more suitable abode in a +complete system of anthropology--the pendant to empirical physics. + +The above is the general idea of metaphysics, which, as more was +expected from it than could be looked for with justice, and as these +pleasant expectations were unfortunately never realized, fell into +general disrepute. Our Critique must have fully convinced the reader +that, although metaphysics cannot form the foundation of religion, +it must always be one of its most important bulwarks, and that human +reason, which naturally pursues a dialectical course, cannot do +without this science, which checks its tendencies towards dialectic +and, by elevating reason to a scientific and clear self-knowledge, +prevents the ravages which a lawless speculative reason would +infallibly commit in the sphere of morals as well as in that of +religion. We may be sure, therefore, whatever contempt may be thrown +upon metaphysics by those who judge a science not by its own nature, +but according to the accidental effects it may have produced, that +it can never be completely abandoned, that we must always return to +it as to a beloved one who has been for a time estranged, because the +questions with which it is engaged relate to the highest aims of +humanity, and reason must always labour either to attain to settled +views in regard to these, or to destroy those which others have +already established. + +Metaphysic, therefore--that of nature, as well as that of ethics, +but in an especial manner the criticism which forms the propaedeutic +to all the operations of reason--forms properly that department of +knowledge which may be termed, in the truest sense of the word, +philosophy. The path which it pursues is that of science, which, +when it has once been discovered, is never lost, and never misleads. +Mathematics, natural science, the common experience of men, have a +high value as means, for the most part, to accidental ends--but at +last also, to those which are necessary and essential to the existence +of humanity. But to guide them to this high goal, they require the +aid of rational cognition on the basis of pure conceptions, which, +be it termed as it may, is properly nothing but metaphysics. + +For the same reason, metaphysics forms likewise the completion of +the culture of human reason. In this respect, it is indispensable, +setting aside altogether the influence which it exerts as a science. +For its subject-matter is the elements and highest maxims of reason, +which form the basis of the possibility of some sciences and of the +use of all. That, as a purely speculative science, it is more useful +in preventing error than in the extension of knowledge, does not +detract from its value; on the contrary, the supreme office of +censor which it occupies assures to it the highest authority and +importance. This office it administers for the purpose of securing +order, harmony, and well-being to science, and of directing its +noble and fruitful labours to the highest possible aim--the +happiness of all mankind. + + + +CHAPTER IV. The History of Pure Reason. + +This title is placed here merely for the purpose of designating a +division of the system of pure reason of which I do not intend to +treat at present. I shall content myself with casting a cursory +glance, from a purely transcendental point of view--that of the nature +of pure reason--on the labours of philosophers up to the present time. +They have aimed at erecting an edifice of philosophy; but to my eye +this edifice appears to be in a very ruinous condition. + +It is very remarkable, although naturally it could not have been +otherwise, that, in the infancy of philosophy, the study of the nature +of God and the constitution of a future world formed the commencement, +rather than the conclusion, as we should have it, of the speculative +efforts of the human mind. However rude the religious conceptions +generated by the remains of the old manners and customs of a less +cultivated time, the intelligent classes were not thereby prevented +from devoting themselves to free inquiry into the existence and nature +of God; and they easily saw that there could be no surer way of +pleasing the invisible ruler of the world, and of attaining to +happiness in another world at least, than a good and honest course +of life in this. Thus theology and morals formed the two chief +motives, or rather the points of attraction in all abstract inquiries. +But it was the former that especially occupied the attention of +speculative reason, and which afterwards became so celebrated under +the name of metaphysics. + +I shall not at present indicate the periods of time at which the +greatest changes in metaphysics took place, but shall merely give a +hasty sketch of the different ideas which occasioned the most +important revolutions in this sphere of thought. There are three +different ends in relation to which these revolutions have taken +place. + +1. In relation to the object of the cognition of reason, +philosophers may be divided into sensualists and intellectualists. +Epicurus may be regarded as the head of the former, Plato of the +latter. The distinction here signalized, subtle as it is, dates from +the earliest times, and was long maintained. The former asserted +that reality resides in sensuous objects alone, and that everything +else is merely imaginary; the latter, that the senses are the +parents of illusion and that truth is to be found in the understanding +alone. The former did not deny to the conceptions of the understanding +a certain kind of reality; but with them it was merely logical, with +the others it was mystical. The former admitted intellectual +conceptions, but declared that sensuous objects alone possessed real +existence. The latter maintained that all real objects were +intelligible, and believed that the pure understanding possessed a +faculty of intuition apart from sense, which, in their opinion, served +only to confuse the ideas of the understanding. + +2. In relation to the origin of the pure cognitions of reason, we +find one school maintaining that they are derived entirely from +experience, and another that they have their origin in reason alone. +Aristotle may be regarded as the bead of the empiricists, and Plato +of the noologists. Locke, the follower of Aristotle in modern times, +and Leibnitz of Plato (although he cannot be said to have imitated +him in his mysticism), have not been able to bring this question to +a settled conclusion. The procedure of Epicurus in his sensual system, +in which he always restricted his conclusions to the sphere of +experience, was much more consequent than that of Aristotle and Locke. +The latter especially, after having derived all the conceptions and +principles of the mind from experience, goes so far, in the employment +of these conceptions and principles, as to maintain that we can +prove the existence of God and the existence of God and the +immortality of them objects lying beyond the soul--both of them of +possible experience--with the same force of demonstration as any +mathematical proposition. + +3. In relation to method. Method is procedure according to +principles. We may divide the methods at present employed in the field +of inquiry into the naturalistic and the scientific. The naturalist +of pure reason lays it down as his principle that common reason, +without the aid of science--which he calls sound reason, or common +sense--can give a more satisfactory answer to the most important +questions of metaphysics than speculation is able to do. He must +maintain, therefore, that we can determine the content and +circumference of the moon more certainly by the naked eye, than by +the aid of mathematical reasoning. But this system is mere misology +reduced to principles; and, what is the most absurd thing in this +doctrine, the neglect of all scientific means is paraded as a peculiar +method of extending our cognition. As regards those who are +naturalists because they know no better, they are certainly not to +be blamed. They follow common sense, without parading their +ignorance as a method which is to teach us the wonderful secret, how +we are to find the truth which lies at the bottom of the well of +Democritus. + + Quod sapio satis est mihi, non ego curo Esse quod + Arcesilas aerumnosique Solones. PERSIUS + -- Satirae, iii. 78-79. + +is their motto, under which they may lead a pleasant and praiseworthy +life, without troubling themselves with science or troubling science +with them. + +As regards those who wish to pursue a scientific method, they have +now the choice of following either the dogmatical or the sceptical, +while they are bound never to desert the systematic mode of procedure. +When I mention, in relation to the former, the celebrated Wolf, and +as regards the latter, David Hume, I may leave, in accordance with +my present intention, all others unnamed. The critical path alone is +still open. If my reader has been kind and patient enough to accompany +me on this hitherto untravelled route, he can now judge whether, if +he and others will contribute their exertions towards making this +narrow footpath a high road of thought, that which many centuries have +failed to accomplish may not be executed before the close of the +present--namely, to bring Reason to perfect contentment in regard to +that which has always, but without permanent results, occupied her +powers and engaged her ardent desire for knowledge. diff --git a/tests/org.simantics.db.tests/data/graph.txt
