[3] PREFACE TO THE FIRST EDITION So far as morality is based upon the conception of man as a free agent who, just because he is free, binds himself through his reason to unconditioned laws, it stands in need neither of the idea of another Being over him, for him to apprehend his duty, nor of an incentive other than the law itself, for him to do his duty. At least it is man's own fault if he is subject to such a need; and if he is, this need can be relieved through nothing outside himself: for whatever does not originate in himself and his own freedom in no way compensates for the deficiency of his morality. Hence for its own sake morality does not need religion at all (whether objectively, as regards willing, or subjectively, as regards ability [to act]); by virtue of pure practical reason it is self-sufficient. For since its laws are binding, as the highest condition (itself unconditioned) of all ends, through the bare form of universal legality of the maxims, which must be chosen accordingly, morality requires absolutely no material determining ground of free choicew,* that is, no end, in order either to know what duty is or to impel the performance of duty. On the contrary, when it is a question of duty, morality is perfectly able to ignore all ends, and [4] it ought to do so. Thus, for example, in order to know whether I should (or indeed can) be truthful in my testimony before a court, or whether I should be faithful in accounting for another man's property entrusted to me, it is not at all necessary for me to search for an end which I might perhaps propose to achieve with my declaration, since it matters not at all what sort of end this is; indeed, the man who finds it needful, when his avowal is lawfully demanded, to look about him for some kind of [ulterior] end, is, by this very fact, already contemptible. But although for its own sake morality needs no representation of an end which must precede the determining of the will, it is quite possible that it is necessarily related to such an end, taken not as the ground but as the [sum of] inevitable consequences of maxims adopted as conformable to that end. For in the absence of all reference to an end no determination of the will can take place in man, since such determination cannot be followed by no effect whatever; and the representation of the effect must be capable of being accepted, not, indeed, as the basis for the determination of the willw and as an end antecedently aimed at, but yet as an end conceived of as the result ensuing from the will'sw determination through the law (finis in consequentiam veniens). Without an end of this sort a willw, envisaging to itself no definite goal1 for a contemplated act, either objective or subjective (which it has, or ought to have, in view), is indeed informed as to how it ought to act, but not whither, and so can achieve no satisfaction. It is true, therefore, that morality requires no end for right conduct; the law, which contains the formal condition of the use of freedom in general, suffices. Yet an end does arise out of morality; for how the question, What is to result from this right conduct of ours? is to be answered, and towards what, as an end--even granted it may not be wholly subject to our control--we might direct our actions and abstentions so as at least to be in harmony with that end: these cannot possibly be matters of indifference to reason. Hence the end is no more than an idea of an object which takes the formal condition of all such ends as we ought to have (duty) and combines it with whatever is conditioned, and in harmony with duty, in all the ends which we do have (happiness proportioned to obedience to duty)--that is to say, the idea of a highest good in the world for whose possibility we must postulate a higher, moral, [5] most holy, and omnipotent Being which alone can unite the two elements of this highest good. Yet (viewed practically) this idea is not an empty one, for it does meet our natural need to conceive of some sort of final end for all our actions and abstentions, taken as a whole, an end which can be justified by reason and the absence of which would be a hindrance to moral decision. Most important of all, however, this idea arises out of morality and is not its basis; it is an end the adoption of which as one's own presupposes basic ethical principles. Therefore it cannot be a matter of unconcern to morality as to whether or not it forms for itself the concept of a final end of all things (harmony with which, while not multiplying men's duties, yet provides them with a special point of focus for the unification of all ends); for only thereby can objective, practical reality be given to the union of the purposiveness arising from freedom with the purposiveness of nature, a union with which we cannot possibly dispense. Take a man who, honoring the moral law, allows the thought to occur to him (he can scarcely avoid doing so) of what sort of world he would create, under the guidance of practical reason, were such a thing in his power, a world into which, moreover, he would place himself as a member. He would not merely make the very choice which is determined by that moral idea of the highest good, were he vouchsafed solely the right to choose; he would also will that [such] a world should by all means come into existence (because the moral law demands that the highest good possible through our agency should be realized) and he would so will even though, in accordance with this idea, he saw himself in danger of paying in his own person a heavy price in happiness--it being possible that he might not be adequate to the [moral] demands of the idea, demands which reason lays down as conditioning happiness. Accordingly he would feel compelled by reason to avow this judgment with complete impartiality, as though it were rendered by another and yet, at the same time, as his own; whereby man gives evidence of the need, morally effected in him, of also conceiving a final end for his duties, as their consequence. Morality thus leads ineluctably to religion, through which it extends itself* to the idea of a powerful moral Lawgiver, outside [6] of mankind, for Whose will that is the final end (of creation) which at the same time can and ought to be man's final end. [7] If morality finds in the holiness of its law an object of the greatest respect, then at the level of religion it presents the ultimate cause, which consummates those laws, as an object of adoration and thus appears in its majesty. But anything, even the most sublime, dwindles under the hands of men when they turn the idea of it to their own use. What can truly be venerated only so far as respect for it is free must adapt itself to those forms which can be rendered authoritative only by means of coercive laws; and what of its own accord exposes itself to the public criticism of everyone must submit itself to a criticism which has power, i.e., a censorship. Meanwhile, since the command, Obey the authorities! is also moral, and since obedience to it, as to all injunctions of duty, can be drawn into religion, it is fitting that a treatise which is dedicated to the definite concept of religion should itself present an example of this obedience, which, however, can be evinced not through attention merely to law in the form of a single state regulation and blindness with respect to every other, but only through combined respect for all [regulations] taken together. Now the theologian who passes on books can be appointed either as one who is to care for the soul's welfare alone or as one who is also to care for the welfare of the sciences; the first judge is [8] appointed merely as a divine; the second, as a scholar also. It rests with the second, as a member of a public institution to which (under the name of a university) all the sciences are entrusted for cultivation and defense against interference, to limit the usurpations of the first by the stipulation that his censorship shall create no disturbance in the field of the sciences. And when both judges are Biblical theologians, the superior censorship will pertain to the second as a member of the university and as belonging to the faculty which has been charged with the treatment of this theology: for, as regards the first concern (the welfare of souls), both have a mandate alike; but, as regards the second (the welfare of the sciences), the theologian in his capacity as university scholar has, in addition, a special function to perform. If we depart from this rule things must finally come to the pass to which they came of yore (for example, at the time of Galileo), where the Biblical theologian, in order to humble the pride of the sciences and to spare himself labor in connection with them, might actually venture an invasion into astronomy, or some other science, as for example the ancient history of the earth, and -- like those tribes who, finding that they do not have either the means or the resolution sufficient to defend themselves against threatened attacks, transform all about them into a wilderness -- might arrest all the endeavors of human reason. Among the sciences, however, there is, over and against Biblical theology, a philosophical theology, which is an estate entrusted to another faculty. So long as this philosophical theology remains within the limits of reason alone, and for the confirmation and exposition of its propositions makes use of history, sayings, books of all peoples, even the Bible, but only for itself, without wishing to carry these propositions into Biblical theology or to change the latter's public doctrines -- a privilege of divines -- it must have complete freedom to expand as far as its science reaches. And although the right of censorship of the theologian (regarded merely as a divine)1 cannot be impugned when it has been shown that the philosopher has really overstepped his limits and committed trespass upon theology, yet, the instant this is in doubt and a question arises whether, in writing or in some other public utterance of the philosopher, this trespass has indeed occurred, the superior censorship can belong only to the Biblical theologian, and to him as a member of his faculty; for he has been assigned to care [9] for the second interest of the commonwealth, namely, the prosperity of the sciences, and has been appointed just as legally as has the other [the theologian regarded as a divine]. And under such circumstances it is indeed to this faculty and not to the philosophical that the ultimate censorship belongs; for the former alone is privileged in respect of certain doctrines, while the latter investigates its doctrines freely and openly; hence only the former can enter a complaint that its exclusive rights have been violated. But despite the approximation of the two bodies of doctrine to one another and the anxiety lest the philosophical faculty overstep its limits, doubt relating to such trespass is easily prevented if it is borne in mind that the mischief occurs not through the philosopher's borrowing something from Biblical theology, in order to use it for his purpose -- even granting that the philosopher uses what he borrows from it in a meaning suited to naked reason but perhaps not pleasing to his theology -- but only so far as he imports something into it and thereby seeks to direct it to ends other than those which its own economy sanctions. For Biblical theology will itself not want to deny that it contains a great deal in common with the teachings of unassisted reason and, in addition, much that belongs to historical and philological lore, and that it is subject to the censorship of these [disciplines]. Thus, for example, we cannot say that the teacher of natural rights, who borrows many a classical expression and formula for his philosophical doctrine of rights from the codex of the Romans, thereby trespasses -- even if, as often happens, he does not employ them in exactly the same sense in which, according to the expositors of Roman Law, they were to be taken -- so long as he does not wish jurists proper, and even the courts of law, also to use them thus. For were that not within his competence, we could, conversely, accuse the Biblical theologian or the statutory jurist of trespassing countless times on the province of philosophy, because both must borrow from philosophy very often, though only to mutual advantage, since neither can dispense with reason, nor, where science is concerned, with philosophy. Were Biblical theology to determine, wherever possible, to have nothing to do with reason in things religious, we can easily foresee on which side would be the loss; for a religion which rashly declares war on reason will not be able to hold out in the long run against it. I will even venture to ask whether it would not be beneficial, [10] upon completion of the academic instruction in Biblical theology, always to add, by way of conclusion, as necessary to the complete equipment of the candidate, a special course of lectures on the purely philosophical theory of religion (which avails itself of everything, including the Bible), with such a book as this, perhaps, as the text (or any other, if a better one of the same kind can be found). For the sciences derive pure benefit from separation, so far as each first constitutes a whole by itself; and not until they are so constituted should the attempt be made to survey them in combination. Let the Biblical theologian, then, be at one with the philosopher, or let him believe himself obliged to refute him, if only he hears him. Only thus can he be forearmed against all the difficulties which the philosopher might make for him. To conceal these, or indeed to decry them as ungodly, is a paltry device which does not stand the test; while to mix the two -- the Biblical theologian, for his part, casting but an occasional fleeting glance at philosophy -- is to lack thoroughness, with the result that in the end no one really knows how he stands towards the theory of religion as a whole. In order to make apparent the relation of religion to human nature (endowed in part with good, in part with evil predispositions), I represent, in the four following essays, the relationship of the good and evil principles as that of two self-subsistent active causes influencing men. The first essay has already been printed in the Berlinische Monatsschrift of April, 1792, but could not be omitted here, because of the close coherence of the subject- matter in this work, which contains, in the three essays now added, the complete development of the first. The reader is asked to forgive the orthography of the first sheets (which differs from mine) in view of the variety of hands which have worked on the copy and the shortness of time left me for revision. [11] PREFACE TO THE SECOND EDITION For this Edition nothing has been altered except misprints and a few expressions which have been improved. New supplementary material, indicated by a dagger (+), is placed at the foot of the text. Regarding the title of this work (for doubts have been expressed about the intention concealed thereunder) I note: that since, after all, revelation can certainly embrace the pure religion of reason, while, conversely, the second cannot include what is historical in the first, I shall be able [experimentally] to regard the first as the wider sphere of faith, which includes within itself the second, as a narrower one (not like two circles external to one another, but like concentric circles). The philosopher, as a teacher of pure reason (from unassisted principles a priori), must confine himself within the narrower circle, and, in so doing, must waive consideration of all experience. From this standpoint I can also make a second experiment, namely, to start from some alleged revelation or other and, leaving out of consideration the pure religion of reason (so far as it constitutes a self-sufficient system), to examine in a fragmentary manner this revelation, as an historical system, in the light of moral concepts; and then to see whether it does not lead back to the very same pure rational system of religion. The latter, though not from the theoretical point of view (and the technico-practical point of view of pedagogical method, as a technology, must also be reckoned under this head) may yet, from the morally practical standpoint, be self-sufficient and adequate for genuine religion, which, indeed, as a rational concept a priori (remaining over after everything empirical has been taken away), obtains only in this [morally practical] relation. If this experiment is successful we shall be able to say that reason can be found to be not only compatible with Scripture but also at one with it, so that he who follows one (under guidance of moral concepts) will not fail to conform to the other. Were this not so, we should have either two religions in one individual, which is absurd, or else one religion and one cult,1 in which case, since the second is not (like religion) an end in itself but only possesses value as a means, they would often have to be shaken up together [12] that they might, for a short while, be united; though directly, like oil and water, they must needs separate from one another, and the purely moral (the religion of reason) be allowed to float on top. I noted in the first Preface that this unification, or the attempt at it, is a task to which the philosophical investigator of religion has every right, and is not a trespass upon the exclusive rights of the Biblical theologian. Since then I have found this assertion made in the Moral (Part I, pp. 5-11) of the late Michaelis,1 a man well versed in both departments, and applied throughout his entire work; and the higher faculty did not find therein anything prejudicial to their rights. In this Second Edition I have not been able, as I should have liked, to take cognizance of the judgments passed upon this book by worthy men, named and unnamed, since (as with all foreign literary intelligence) these arrive in our parts very late. This is particularly true of the Annotationes quaedam theologicae, etc. of the renowned Hr. D. Storr2 in TŸbingen, who has examined my book with his accustomed sagacity and with an industry and fairness deserving the greatest thanks. I have it in mind to answer him, but cannot venture to promise to do so because of the peculiar difficulties which age sets in the way of working with abstract ideas. But there is a review in Number 29 of the Neueste Kritische Nachrichten, of Greifswald,3 which I can despatch as briefly as the reviewer did the book itself. For the book, in his judgment, is nothing but an answer to the question which I myself posed: "How is the ecclesiastical system of dogmatics, in its concepts and doctrines, possible according to pure (theoretical and practical) reason?" This essay [he claims] does not concern those4 who have no knowledge and understanding of his (Kant's) system and have no desire to be able to understand it -- by them it may be looked upon as non-existent. I answer thus: To understand this book in its essential content, only common morality is needed, without meddling with the Critique of Practical Reason, still less with the theoretical Critique. When, for example, virtue as skill in actions [13] conforming to duty (according to their legality) is called virtus phÏnomenon, and the same virtue as an enduring disposition towards such actions from duty (because of their morality) is called virtus noumenon, these expressions are used only because of the schools; while the matter itself is contained, though in other words, in the most popular children's instruction and sermons, and is easily understood. Would that as much could be said for the mysteries concerning the divine nature which are numbered among religious teachings, mysteries introduced into the catechism as though they were wholly popular, but which, ultimately, must first be transformed into moral concepts if they are to become comprehensible to everyone! Kšnigsberg, 26 January, 1794. NOTES: w [3] For an explanation of the "w" see the "Preface to the Second Edition of this Translation," page cxxxix. * [3] Those who, in the conception of duty, are not satisfied with the merely formal determining ground as such (conformity to law) as the basis of determination, do indeed admit that such a basis cannot be discovered in self-love directed to one's own comfort. Hence there remain but two determining grounds: one, which is rational, namely, one's own perfection, and another, which is empirical, the happiness of others.1 Now if they do not conceive of the first of these as the moral determining ground (a will, namely, unconditionally obedient to the law) which is necessarily unique-- and if they so interpreted it they would be expounding in a circle -- they would have to have in mind man's natural perfection, so far as it is capable of enhancement, and this can be of many kinds, such as skill in the arts and sciences, taste, bodily adroitness, etc. But these are always good only on the condition that their use does not conflict with the moral law (which alone commands unconditionally); set up as an end, therefore, perfection cannot be the principle of concepts of duty. The same holds for the end which aims at the happiness of other men. For an act must, first of all, itself be weighed according to the moral law before it is directed to the happiness of others. The requirement laid down by this end, therefore, is a duty only conditionally and cannot serve as the supreme principle of moral maxims. 1 [3] [fremde GlŸckseligkeit. We have almost always translated GlŸckseligkeit as happiness.] 1 [4] [Gegenstand] * [5] If the proposition, There is a God, hence there is a highest good in the world, is to arise (as a dogma) from morality alone, it is a synthetic a priori proposition: for even thought accepted only for practical reference, it does yet [6] pass beyond the concept of duty which morality contains (and which presupposes merely the formal laws, and not the matter, of choicew), and hence cannot analytically be evolved out of morality. But how is such a proposition a priori possible? Agreement with the bare idea of a moral Lawgiver for all men is, indeed, identical with the general moral concept of duty, and so far the proposition commanding this agreement would be analytic. But the acknowledgment of His existence asserts more than the bare possibility of such a thing. The key to the solution of this problem, so far as I believe myself to understand it, I can only indicate here and not develop. An end is always the object of an inclination, that is, of an immediate craving for possession of a thing through one's action, just as the law (which commands practically) is an object of respect. An objective end (i.e., the end which we ought to have) is that which is proposed to us as such by reason alone. The end which embraces the unavoidable and at the same time sufficient condition of all other ends is the final end. The subjective final end of rational worldly beings is their own happiness (each of them has this end by virtue of having a nature dependent upon sensuous objects, and hence it would be absurd to say that anyone ought to have it) and all practical propositions which are based on this final end are synthetic, and at the same time empirical. But that everyone ought to make the highest good possible in the world a final end is a synthetic practical proposition a priori (and indeed objectively practical) given by pure reason; for it is a proposition which goes beyond the concept of duties in this world and adds a consequence (an effect) thereof which is not contained in the moral laws and therefore cannot be evolved out of them analytically. For these laws command absolutely, be the consequence what it will; indeed, they even require that the consideration of such consequence be completely waived when a particular act is concerned; and thereby they make duty an object of highest respect without offering or proposing to us an end (or a final end) such as would have to constitute duty's recommendation and the incentive to the fulfilment of our duty. All men could have sufficient incentive if (as they should) they adhered solely to the dictation of pure reason in the law. What need have they to know the outcome of their moral actions and abstentions, an outcome which the world's course will bring about? It suffices for them that they do their duty; even though all things end with earthly life and though, in this life, happiness and desert may never meet. And yet it is one of the inescapable limitations of man and of his faculty of practical reason (a limitation, perhaps, of all other worldly beings as well) to have regard, in every action, to the consequence thereof, in order to discover therein what could serve him as an end and also prove the purity of his intention--which consequence, though last in practice (nexu effectivo) is yet first in representation and intention (nexu finali). In this end, if directly presented to him by reason alone, man seeks something that he can love; therefore the law, which merely arouses his respect, even [7] though it does not acknowledge this object of love as a necessity does yet extend itself on its behalf by including the moral goal of reason among its determining grounds. That is, the proposition: Make the highest good possible in the world your own final end! is a synthetic proposition a priori, which is introduced by the moral law itself; although practical reason does, indeed, extend itself therein beyond the law. This extension is possible because of the moral law's being taken in relation to the natural characteristic of man, that for all his actions he must conceive of an end over and above the law (a characteristic which makes man an object of experience). And further, this extension (as with theoretical propositions a priori which are synthetic) is possible only because this end embraces the a priori principle of the knowledge of the determining grounds in experience of a free willw, so far as this experience, by exhibiting the effects of morality in its ends, gives objective though merely practical reality to the concept of morality as causal in the world. But if, now, the strictest obedience to moral laws is to be considered the cause of the ushering in of the highest good (as end), then, since human capacity does not suffice for bringing about happiness in the world proportionate to worthiness to be happy, an omnipotent moral Being must be postulated as ruler of the world, under whose care this [balance] occurs. That is, morality leads inevitably to religion. 1 [8] [Italics not in the text.] 1 [11] [Cultus, ceremonial worship] 1 [12] [Johann David Michaelis, 1717-1791; celebrated Orientalist and Biblical scholar; the book referred to was published posthumously in 1792.] 2 [12] Gottlob Christian Storr, 1746-1805, Professor of Theology in TŸbingen, and later court-preacher in Stuttgart.
