They thus, in fact, left out the second element of the summum bonum namely, personal happiness, placing it solely in action and satisfaction with one's own personal worth, thus including it in the consciousness of being morally minded, in which they Might have been sufficiently refuted by the voice of their own nature.
The doctrine of Christianity,* even if we do not yet consider it as
* It is commonly held that the Christian precept of morality has no advantage in respect of purity over the moral conceptions of the Stoics; the distinction between them is, however, very obvious. The Stoic system made the consciousness of strength of mind the pivot on which all moral dispositions should turn; and although its disciples spoke of duties and even defined them very well, yet they placed the spring and proper determining principle of the will in an elevation of the mind above the lower springs of the senses, which owe their power only to weakness of mind. With them therefore, virtue was a sort of heroism in the wise man raising himself above the animal nature of man, is sufficient for Himself, and, while he prescribes duties to others, is himself raised above them, and is not subject to any temptation to transgress the moral law. All this, however, they could not have done if they had conceived this law in all its purity and strictness, as the precept of the Gospel does. When I give the name idea to a perfection to which nothing adequate can be given in experience, it does not follow that the moral ideas are thing transcendent, that is something of which we could not even determine the concept adequately, or of which it is uncer- tain whether there is any object corresponding to it at all, as is the case with the ideas of speculative reason; on the contrary, being types of practical perfection, they serve as the indispensable rule of conduct and likewise as the standard of comparison. Now if I consider Christian morals on their philosophical side, then compared with the ideas of the Greek schools, they would appear as follows: the ideas of the Cynics, the Epicu- reans, the Stoics, and the Christians are: simplicity of nature, prudence, wisdom, and holiness. In respect of the way of attaining them, the Greek schools were distin- guished from one another thus that the Cynics only required common sense, the others the path of science, but both found the mere use of natural powers sufficient for the purpose. Christian morality, because its precept is framed (as a moral precept must be) so pure and unyielding, takes from man all confidence that be can be fully adequate to it, at least in this life, but again sets it up by enabling us to hope that if we act as well as it is in our power to do, then what is not in our power will come in to our aid from another source, whether we know how this may be or not. Aristotle and Plato differed only as to the origin of our moral conceptions.

The Critique of Practical Reason
a religious doctrine, gives, touching this point, a conception of the summum bonum (the kingdom of God), which alone satisfies the strictest demand of practical reason. The moral law is holy (un- yielding) and demands holiness of morals, although all the moral perfection to which man can attain is still only virtue, that is, a rightful disposition arising from respect for the law, implying con- sciousness of a constant propensity to transgression, or at least a want of purity, that is, a mixture of many spurious (not moral) motives of obedience to the law, consequently a self-esteem com- bined with humility. In respect, then, of the holiness which the Christian law requires, this leaves the creature nothing but a progress in infinitum, but for that very reason it justifies him in hoping for an endless duration of his existence. The worth of a character per- fectly accordant with the moral law is infinite, since the only restric- tion on all possible happiness in the judgement of a wise and all powerful distributor of it is the absence of conformity of rational beings to their duty. But the moral law of itself does not promise any happiness, for according to our conceptions of an order of na- ture in general, this is not necessarily connected with obedience to the law. Now Christian morality supplies this defect (of the second indispensable element of the summum bonum) by representing the world in which rational beings devote themselves with all their soul to the moral law, as a kingdom of God, in which nature and moral- ity are brought into a harmony foreign to each of itself, by a holy Author who makes the derived summum bonum possible. Holiness of life is prescribed to them as a rule even in this life, while the welfare proportioned to it, namely, bliss, is represented as attainable only in an eternity; because the former must always be the pattern of their conduct in every state, and progress towards it is already possible and necessary in this life; while the latter, under the name of happiness, cannot be attained at all in this world (so far as our own power is concerned), and therefore is made simply an object of hope. Nevertheless, the Christian principle of morality itself is not theological (so as to be heteronomy), but is autonomy of pure prac- tical reason, since it does not make the knowledge of God and His will the foundation of these laws, but only of the attainment of the summum bonum, on condition of following these laws, and it does
130
not even place the proper spring of this obedience in the desired results, but solely in the conception of duty, as that of which the faithful observance alone constitutes the worthiness to obtain those happy consequences.
In this manner, the moral laws lead through the conception of the summum bonum as the object and final end of pure practical rea- son to religion, that is, to the recognition of all duties as divine commands, not as sanctions, that is to say, arbitrary ordinances of a foreign and contingent in themselves, but as essential laws of every free will in itself, which, nevertheless, must be regarded as com- mands of the Supreme Being, because it is only from a morally per- fect (holy and good) and at the same time all-powerful will, and consequently only through harmony with this will, that we can hope to attain the summum bonum which the moral law makes it our duty to take as the object of our endeavours. Here again, then, all remains disinterested and founded merely on duty; neither fear nor hope being made the fundamental springs, which if taken as prin- ciples would destroy the whole moral worth of actions. The moral law commands me to make the highest possible good in a world the ultimate object of all my conduct. But I cannot hope to effect this otherwise than by the harmony of my will with that of a holy and good Author of the world; and although the conception of the sum- mum bonum as a whole, in which the greatest happiness is con- ceived as combined in the most exact proportion with the highest degree of moral perfection (possible in creatures), includes my own happiness, yet it is not this that is the determining principle of the will which is enjoined to promote the summum bonum, but the moral law, which, on the contrary, limits by strict conditions my unbounded desire of happiness.
Hence also morality is not properly the doctrine how we should make ourselves happy, but how we should become worthy of happi- ness. It is only when religion is added that there also comes in the hope of participating some day in happiness in proportion as we have endeavoured to be not unworthy of it.
A man is worthy to possess a thing or a state when his possession of it is in harmony with the summum bonum. We can now easily see that all worthiness depends on moral conduct, since in the concep-
Immanuel Kant
131
The Critique of Practical Reason
tion of the summum bonum this constitutes the condition of the rest (which belongs to one's state), namely, the participation of happiness. Now it follows from this that morality should never be treated as a doctrine of happiness, that is, an instruction how to become happy; for it has to do simply with the rational condition (conditio sine qua non) of happiness, not with the means of attaining it. But when mo- rality has been completely expounded (which merely imposes duties instead of providing rules for selfish desires), then first, after the moral desire to promote the summum bonum (to bring the kingdom of God to us) has been awakened, a desire founded on a law, and which could not previously arise in any selfish mind, and when for the be- hoof of this desire the step to religion has been taken, then this ethical doctrine may be also called a doctrine of happiness because the hope of happiness first begins with religion only.
We can also see from this that, when we ask what is God's ultimate end in creating the world, we must not name the happiness of the rational beings in it, but the summum bonum, which adds a further condition to that wish of such beings, namely, the condition of being worthy of happiness, that is, the morality of these same rational be- ings, a condition which alone contains the rule by which only they can hope to share in the former at the hand of a wise Author. For as wisdom, theoretically considered, signifies the knowledge of the sum- mum bonum and, practically, the accordance of the will with the summum bonum, we cannot attribute to a supreme independent wisdom an end based merely on goodness. For we cannot conceive the action of this goodness (in respect of the happiness of rational beings) as suitable to the highest original good, except under the re- strictive conditions of harmony with the holiness* of his will. There-
* In order to make these characteristics of these conceptions clear, I add the remark that whilst we ascribe to God various attributes, the quality of which we also find applicable to creatures, only that in Him they are raised to the highest degree, e. g. , power, knowledge, presence, goodness, etc. , under the designations of omnipotence, omniscience, omnipresence, etc. , there are three that are ascribed to God exclusively, and yet without the addition of greatness, and which are all moral He is the only holy, the only blessed, the only wise, because these conceptions already imply the absence of limitation. In the order of these attributes He is also the holy lawgiver (and creator), the good governor (and preserver) and the just judge, three attributes which include everything by which God is the object of religion, and in conformity with which the metaphysical perfections are added of themselves in the reason.
132
? fore, those who placed the end of creation in the glory of God (pro- vided that this is not conceived anthropomorphically as a desire to be praised) have perhaps hit upon the best expression. For nothing glo- rifies God more than that which is the most estimable thing in the world, respect for his command, the observance of the holy duty that his law imposes on us, when there is added thereto his glorious plan of crowning such a beautiful order of things with corresponding hap- piness. If the latter (to speak humanly) makes Him worthy of love, by the former He is an object of adoration. Even men can never acquire respect by benevolence alone, though they may gain love, so that the greatest beneficence only procures them honour when it is regulated by worthiness.
That in the order of ends, man (and with him every rational be- ing) is an end in himself, that is, that he can never be used merely as a means by any (not even by God) without being at the same time an end also himself, that therefore humanity in our person must be holy to ourselves, this follows now of itself because he is the subject of the moral law, in other words, of that which is holy in itself, and on account of which and in agreement with which alone can any- thing be termed holy. For this moral law is founded on the au- tonomy of his will, as a free will which by its universal laws must necessarily be able to agree with that to which it is to submit itself.

VI. Of the Postulates of Pure Practical Reason Generally.
THEY ALL PROCEED from the principle of morality, which is not a postulate but a law, by which reason determines the will directly, which will, because it is so determined as a pure will, requires these necessary conditions of obedience to its precept. These postulates are not theoretical dogmas but, suppositions practically necessary; while then they do [not] extend our speculative knowledge, they give objective reality to the ideas of speculative reason in general (by means of their reference to what is practical), and give it a right to concepts, the possibility even of which it could not otherwise ven- ture to affirm.
These postulates are those of immortality, freedom positively con- sidered (as the causality of a being so far as he belongs to the intel- ligible world), and the existence of God. The first results from the practically necessary condition of a duration adequate to the com- plete fulfilment of the moral law; the second from the necessary supposition of independence of the sensible world, and of the fac- ulty of determining one's will according to the law of an intelligible world, that is, of freedom; the third from the necessary condition of the existence of the summum bonum in such an intelligible world, by the supposition of the supreme independent good, that is, the existence of God.
Thus the fact that respect for the moral law necessarily makes the summum bonum an object of our endeavours, and the supposition thence resulting of its objective reality, lead through the postulates of practical reason to conceptions which speculative reason might indeed present as problems, but could never solve. Thus it leads: 1. To that one in the solution of which the latter could do nothing but commit paralogisms (namely, that of immortality), because it could not lay hold of the character of permanence, by which to complete the psychological conception of an ultimate subject necessarily as- cribed to the soul in self-consciousness, so as to make it the real conception of a substance, a character which practical reason fur-
134
nishes by the postulate of a duration required for accordance with the moral law in the summum bonum, which is the whole end of practical reason. 2. It leads to that of which speculative reason con- tained nothing but antinomy, the solution of which it could only found on a notion Problematically conceivable indeed, but whose objective reality it could not prove or determine, namely, the cos- mological idea of an intelligible world and the consciousness of our existence in it, by means of the postulate of freedom (the reality of which it lays down by virtue of the moral law), and with it likewise the law of an intelligible world, to which speculative reason could only point, but could not define its conception. 3. What specula- tive reason was able to think, but was obliged to leave undetermined as a mere transcendental ideal, viz. , the theological conception of the first Being, to this it gives significance (in a practical view, that is, as a condition of the possibility of the object of a will determined by that law), namely, as the supreme principle of the summum bonum in an intelligible world, by means of moral legislation in it invested with sovereign power.
Is our knowledge, however, actually extended in this way by pure practical reason, and is that immanent in practical reason which for the speculative was only transcendent? Certainly, but only in a prac- tical point of view. For we do not thereby take knowledge of the nature of our souls, nor of the intelligible world, nor of the Su- preme Being, with respect to what they are in themselves, but we have merely combined the conceptions of them in the practical con- cept of the summum bonum as the object of our will, and this alto- gether a priori, but only by means of the moral law, and merely in reference to it, in respect of the object which it commands. But how freedom is possible, and how we are to conceive this kind of causal- ity theoretically and positively, is not thereby discovered; but only that there is such a causality is postulated by the moral law and in its behoof. It is the same with the remaining ideas, the possibility of which no human intelligence will ever fathom, but the truth of which, on the other hand, no sophistry will ever wrest from the conviction even of the commonest man.

VII. How is it possible to conceive an Extension of Pure Reason in a Practical point of view, without its Knowledge as Speculative being enlarged at the same time?
IN ORDER NOT to be too abstract, we will answer this question at once in its application to the present case. In order to extend a pure cognition practically, there must be an a priori purpose given, that is, an end as object (of the will), which independently of all theo- logical principle is presented as practically necessary by an impera- tive which determines the will directly (a categorical imperative), and in this case that is the summum bonum. This, however, is not possible without presupposing three theoretical conceptions (for which, because they are mere conceptions of pure reason, no corre- sponding intuition can be found, nor consequently by the path of theory any objective reality); namely, freedom, immortality, and God. Thus by the practical law which commands the existence of the highest good possible in a world, the possibility of those objects of pure speculative reason is postulated, and the objective reality which the latter could not assure them. By this the theoretical knowledge of pure reason does indeed obtain an accession; but it consists only in this, that those concepts which otherwise it had to look upon as problematical (merely thinkable) concepts, are now shown assertorially to be such as actually have objects; because practical reason indispensably requires their existence for the possibility of its object, the summum bonum, which practically is absolutely neces- sary, and this justifies theoretical reason in assuming them. But this extension of theoretical reason is no extension of speculative, that is, we cannot make any positive use of it in a theoretical point of view. For as nothing is accomplished in this by practical reason, further than that these concepts are real and actually have their (pos- sible) objects, and nothing in the way of intuition of them is given thereby (which indeed could not be demanded), hence the admis- sion of this reality does not render any synthetical proposition pos- sible. Consequently, this discovery does not in the least help us to
136
extend this knowledge of ours in a speculative point of view, al- though it does in respect of the practical employment of pure rea- son. The above three ideas of speculative reason are still in them- selves not cognitions; they are however (transcendent) thoughts, in which there is nothing impossible. Now, by help of an apodeictic practical law, being necessary conditions of that which it commands to be made an object, they acquire objective reality; that is, we learn from it that they have objects, without being able to point out how the conception of them is related to an object, and this, too, is still not a cognition of these objects; for we cannot thereby form any synthetical judgement about them, nor determine their application theoretically; consequently, we can make no theoretical rational use of them at all, in which use all speculative knowledge of reason consists. Nevertheless, the theoretical knowledge, not indeed of these objects, but of reason generally, is so far enlarged by this, that by the practical postulates objects were given to those ideas, a merely prob- lematical thought having by this means first acquired objective real- ity. There is therefore no extension of the knowledge of given supersensible objects, but an extension of theoretical reason and of its knowledge in respect of the supersensible generally; inasmuch as it is compelled to admit that there are such objects, although it is not able to define them more closely, so as itself to extend this knowl- edge of the objects (which have now been given it on practical grounds, and only for practical use). For this accession, then, pure theoretical reason, for which all those ideas are transcendent and without object, has simply to thank its practical faculty. In this they become immanent and constitutive, being the source of the possi- bility of realizing the necessary object of pure practical reason (the summum bonum); whereas apart from this they are transcendent, and merely regulative principles of speculative reason, which do not require it to assume a new object beyond experience, but only to bring its use in experience nearer to completeness. But when once reason is in possession of this accession, it will go to work with these ideas as speculative reason (properly only to assure the certainty of its practical use) in a negative manner: that is, not extending but clearing up its knowledge so as on one side to keep off anthropo- morphism, as the source of superstition, or seeming extension of
Immanuel Kant
137
The Critique of Practical Reason
these conceptions by supposed experience; and on the other side fanaticism, which promises the same by means of supersensible in- tuition or feelings of the like kind. All these are hindrances to the practical use of pure reason, so that the removal of them may cer- tainly be considered an extension of our knowledge in a practical point of view, without contradicting the admission that for specula- tive purposes reason has not in the least gained by this.
Every employment of reason in respect of an object requires pure concepts of the understanding (categories), without which no object can be conceived. These can be applied to the theoretical employ- ment of reason, i. e. , to that kind of knowledge, only in case an intu- ition (which is always sensible) is taken as a basis, and therefore merely in order to conceive by means of- them an object of possible experi- ence. Now here what have to be thought by means of the categories in order to be known are ideas of reason, which cannot be given in any experience. Only we are not here concerned with the theoretical knowledge of the objects of these ideas, but only with this, whether they have objects at all. This reality is supplied by pure practical rea- son, and theoretical reason has nothing further to do in this but to think those objects by means of categories. This, as we have elsewhere clearly shown, can be done well enough without needing any intu- ition (either sensible or supersensible) because the categories have their seat and origin in the pure understanding, simply as the faculty of thought, before and independently of any intuition, and they always only signify an object in general, no matter in what way it may be given to us. Now when the categories are to be applied to these ideas, it is not possible to give them any object in intuition; but that such an object actually exists, and consequently that the category as a mere form of thought is here not empty but has significance, this is suffi- ciently assured them by an object which practical reason presents be- yond doubt in the concept of the summum bonum, the reality of the conceptions which are required for the possibility of the summum bonum; without, however, effecting by this accession the least exten- sion of our knowledge on theoretical principles.
When these ideas of God, of an intelligible world (the kingdom of God), and of immortality are further determined by predicates taken from our own nature, we must not regard this determination as a
138
sensualizing of those pure rational ideas (anthropomorphism), nor as a transcendent knowledge of supersensible objects; for these predi- cates are no others than understanding and will, considered too in the relation to each other in which they must be conceived in the moral law, and therefore, only so far as a pure practical use is made of them. As to all the rest that belongs to these conceptions psychologically, that is, so far as we observe these faculties of ours empirically in their exercise (e. g. , that the understanding of man is discursive, and its notions therefore not intuitions but thoughts, that these follow one another in time, that his will has its satisfaction always dependent on the existence of its object, etc. , which cannot be the case in the Su- preme Being), from all this we abstract in that case, and then there remains of the notions by which we conceive a pure intelligence noth- ing more than just what is required for the possibility of conceiving a moral law. There is then a knowledge of God indeed, but only for practical purposes, and, if we attempt to extend it to a theoretical knowledge, we find an understanding that has intuitions, not thoughts, a will that is directed to objects on the existence of which its satisfac- tion does not in the least depend (not to mention the transcendental predicates, as, for example, a magnitude of existence, that is duration, which, however, is not in time, the only possible means we have of conceiving existence as magnitude). Now these are all attributes of which we can form no conception that would help to the knowledge of the object, and we learn from this that they can never be used for a theory of supersensible beings, so that on this side they are quite inca- pable of being the foundation of a speculative knowledge, and their use is limited simply to the practice of the moral law.
This last is so obvious, and can be proved so clearly by fact, that we may confidently challenge all pretended natural theologians (a singular name)* to specify (over and above the merely ontological
* Learning is properly only the whole content of the historical sciences. Consequently it is only the teacher of revealed theology that can be called a learned theologian. If, however, we choose to call a man learned who is in possession of the rational sciences (mathematics and philosophy), although even this would be contrary to the significa- tion of the word (which always counts as learning only that which one must be "learned" and which, therefore, he cannot discover of himself by reason), even in that case the philosopher would make too poor a figure with his knowledge of God as a positive science to let himself be called on that account a learned man.

predicates) one single attribute, whether of the understanding or of the will, determining this object of theirs, of which we could not show incontrovertibly that, if we abstract from it everything an- thropomorphic, nothing would remain to us but the mere word, without our being able to connect with it the smallest notion by which we could hope for an extension of theoretical knowledge. But as to the practical, there still remains to us of the attributes of understanding and will the conception of a relation to which objec- tive reality is given by the practical law (which determines a priori precisely this relation of the understanding to the will). When once this is done, then reality is given to the conception of the object of a will morally determined (the conception of the summum bonum), and with it to the conditions of its possibility, the ideas of God, freedom, and immortality, but always only relatively to the practice of the moral law (and not for any speculative purpose).
According to these remarks it is now easy to find the answer to the weighty question whether the notion of God is one belonging to physics (and therefore also to metaphysics, which contains the pure a priori principles of the former in their universal import) or to morals. If we have recourse to God as the Author of all things, in order to explain the arrangements of nature or its changes, this is at least not a physical explanation, and is a complete confession that our philosophy has come to an end, since we are obliged to assume something of which in itself we have otherwise no conception, in order to be able to frame a conception of the possibility of what we see before our eyes. Metaphysics, however, cannot enable us to at- tain by certain inference from the knowledge of this world to the conception of God and to the proof of His existence, for this rea- son, that in order to say that this world could be produced only by a God (according to the conception implied by this word) we should know this world as the most perfect whole possible; and for this purpose should also know all possible worlds (in order to be able to compare them with this); in other words, we should be omniscient. It is absolutely impossible, however, to know the existence of this Being from mere concepts, because every existential proposition, that is, every proposition that affirms the existence of a being of which I frame a concept, is a synthetic proposition, that is, one by
140
which I go beyond that conception and affirm of it more than was thought in the conception itself; namely, that this concept in the understanding has an object corresponding to it outside the under- standing, and this it is obviously impossible to elicit by any reason- ing. There remains, therefore, only one single process possible for reason to attain this knowledge, namely, to start from the supreme principle of its pure practical use (which in every case is directed simply to the existence of something as a consequence of reason) and thus determine its object. Then its inevitable problem, namely, the necessary direction of the will to the summum bonum, discov- ers to us not only the necessity of assuming such a First Being in reference to the possibility of this good in the world, but, what is most remarkable, something which reason in its progress on the path of physical nature altogether failed to find, namely, an accu- rately defined conception of this First Being. As we can know only a small part of this world, and can still less compare it with all pos- sible worlds, we may indeed from its order, design, and greatness, infer a wise, good, powerful, etc. , Author of it, but not that He is all-wise, all-good, all-powerful, etc. It may indeed very well be granted that we should be justified in supplying this inevitable defect by a legitimate and reasonable hypothesis; namely, that when wisdom, goodness, etc, are displayed in all the parts that offer themselves to our nearer knowledge, it is just the same in all the rest, and that it would therefore be reasonable to ascribe all possible perfections to the Author of the world, but these are not strict logical inferences in which we can pride ourselves on our insight, but only permitted conclusions in which we may be indulged and which require fur- ther recommendation before we can make use of them. On the path of empirical inquiry then (physics), the conception of God remains always a conception of the perfection of the First Being not accu- rately enough determined to be held adequate to the conception of Deity. (With metaphysic in its transcendental part nothing what- ever can be accomplished. )
When I now try to test this conception by reference to the object of practical reason, I find that the moral principle admits as possible only the conception of an Author of the world possessed of the highest perfection. He must be omniscient, in order to know my

The Critique of Practical Reason
conduct up to the inmost root of my mental state in all possible cases and into all future time; omnipotent, in order to allot to it its fitting consequences; similarly He must be omnipresent, eternal, etc. Thus the moral law, by means of the conception of the sum- mum bonum as the object of a pure practical reason, determines the concept of the First Being as the Supreme Being; a thing which the physical (and in its higher development the metaphysical), in other words, the whole speculative course of reason, was unable to effect. The conception of God, then, is one that belongs originally not to physics, i. e. , to speculative reason, but to morals. The same may be said of the other conceptions of reason of which we have treated above as postulates of it in its practical use.
In the history of Grecian philosophy we find no distinct traces of a pure rational theology earlier than Anaxagoras; but this is not because the older philosophers had not intelligence or penetration enough to raise themselves to it by the path of speculation, at least with the aid of a thoroughly reasonable hypothesis. What could have been easier, what more natural, than the thought which of itself occurs to every- one, to assume instead of several causes of the world, instead of an indeterminate degree of perfection, a single rational cause having all perfection? But the evils in the world seemed to them to be much too serious objections to allow them to feel themselves justified in such a hypothesis. They showed intelligence and penetration then in this very point, that they did not allow themselves to adopt it, but on the contrary looked about amongst natural causes to see if they could not find in them the qualities and power required for a First Being. But when this acute people had advanced so far in their investigations of nature as to treat even moral questions philosophically, on which other nations had never done anything but talk, then first they found a new and practical want, which did not fail to give definiteness to their conception of the First Being: and in this the speculative reason played the part of spectator, or at best had the merit of embellishing a con- ception that had not grown on its own ground, and of applying a series of confirmations from the study of nature now brought for- ward for the first time, not indeed to strengthen the authority of this conception (which was already established), but rather to make a show with a supposed discovery of theoretical reason.
142
From these remarks, the reader of the Critique of Pure Specula- tive Reason will be thoroughly convinced how highly necessary that laborious deduction of the categories was, and how fruitful for the- ology and morals. For if, on the one hand, we place them in pure understanding, it is by this deduction alone that we can be pre- vented from regarding them, with Plato, as innate, and founding on them extravagant pretensions to theories of the supersensible, to which we can see no end, and by which we should make theology a magic lantern of chimeras; on the other hand, if we regard them as acquired, this deduction saves us from restricting, with Epicurus, all and every use of them, even for practical purposes, to the objects and motives of the senses. But now that the Critique has shown by that deduction, first, that they are not of empirical origin, but have their seat and source a priori in the pure understanding; secondly, that as they refer to objects in general independently of the intu- ition of them, hence, although they cannot effect theoretical knowl- edge, except in application to empirical objects, yet when applied to an object given by pure practical reason they enable us to conceive the supersensible definitely, only so far, however, as it is defined by such predicates as are necessarily connected with the pure practical purpose given a priori and with its possibility. The speculative re- striction of pure reason and its practical extension bring it into that relation of equality in which reason in general can be employed suitably to its end, and this example proves better than any other that the path to wisdom, if it is to be made sure and not to be impassable or misleading, must with us men inevitably pass through science; but it is not till this is complete that we can be convinced that it leads to this goal.

VIII. Of Belief from a Requirement of Pure Reason.
A WANT OR REQUIREMENT of pure reason in its speculative use leads only to a hypothesis; that of pure practical reason to a postulate; for in the former case I ascend from the result as high as I please in the series of causes, not in order to give objective reality to the result (e. g. , the causal connection of things and changes in the world), but in order thoroughly to satisfy my inquiring reason in respect of it. Thus I see before me order and design in nature, and need not resort to specula- tion to assure myself of their reality, but to explain them I have to presuppose a Deity as their cause; and then since the inference from an effect to a definite cause is always uncertain and doubtful, espe- cially to a cause so precise and so perfectly defined as we have to conceive in God, hence the highest degree of certainty to which this pre-supposition can be brought is that it is the most rational opinion for us men. * On the other hand, a requirement of pure practical rea- son is based on a duty, that of making something (the summum bonum) the object of my will so as to promote it with all my powers; in which case I must suppose its possibility and, consequently, also the conditions necessary thereto, namely, God, freedom, and immor- tality; since I cannot prove these by my speculative reason, although neither can I refute them. This duty is founded on something that is indeed quite independent of these suppositions and is of itself apodeictically certain, namely, the moral law; and so far it needs no
* But even here we should not be able to allege a requirement of reason, if we had not before our eyes a problematical, but yet inevitable, conception of reason, namely, that of an absolutely necessary being. This conception now seeks to be defined, and this, in addition to the tendency to extend itself, is the objective ground of a requirement of speculative reason, namely, to have a more precise definition of the conception of a necessary being which is to serve as the first cause of other beings, so as to make these latter knowable by some means. Without such antecedent necessary prob- lems there are no requirements- at least not of pure reason- the rest are requirements of inclination.

? further support by theoretical views as to the inner constitution of things, the secret final aim of the order of the world, or a presiding ruler thereof, in order to bind me in the most perfect manner to act in unconditional conformity to the law. But the subjective effect of this law, namely, the mental disposition conformed to it and made neces- sary by it, to promote the practically possible summum bonum, this pre-supposes at least that the latter is possible, for it would be practi- cally impossible to strive after the object of a conception which at bottom was empty and had no object. Now the above-mentioned postulates concern only the physical or metaphysical conditions of the possibility of the summum bonum; in a word, those which lie in the nature of things; not, however, for the sake of an arbitrary specu- lative purpose, but of a practically necessary end of a pure rational will, which in this case does not choose, but obeys an inexorable com- mand of reason, the foundation of which is objective, in the constitu- tion of things as they must be universally judged by pure reason, and is not based on inclination; for we are in nowise justified in assuming, on account of what we wish on merely subjective grounds, that the means thereto are possible or that its object is real. This, then, is an absolutely necessary requirement, and what it pre-supposes is not merely justified as an allowable hypothesis, but as a postulate in a practical point of view; and admitting that the pure moral law inexo- rably binds every man as a command (not as a rule of prudence), the righteous man may say: "I will that there be a God, that my existence in this world be also an existence outside the chain of physical causes and in a pure world of the understanding, and lastly, that my dura- tion be endless; I firmly abide by this, and will not let this faith be taken from me; for in this instance alone my interest, because I must not relax anything of it, inevitably determines my judgement, with- out regarding sophistries, however unable I may be to answer them or to oppose them with others more plausible. *
* In the Deutsches Museum, February, 1787, there is a dissertation by a very subtle and clear-headed man, the late Wizenmann, whose early death is to be lamented, in which he disputes the right to argue from a want to the objective reality of its object, and illustrates the point by the example of a man in love, who having fooled himself into an idea of beauty, which is merely a chimera of his own brain, would fain conclude that such an object really exists somewhere.

The Critique of Practical Reason
In order to prevent misconception in the use of a notion as yet so unusual as that of a faith of pure practical reason, let me be permit- ted to add one more remark. It might almost seem as if this rational faith were here announced as itself a command, namely, that we should assume the summum bonum as possible. But a faith that is commanded is nonsense. Let the preceding analysis, however, be remembered of what is required to be supposed in the conception of the summum bonum, and it will be seen that it cannot be com- manded to assume this possibility, and no practical disposition of mind is required to admit it; but that speculative reason must con- cede it without being asked, for no one can affirm that it is impos- sible in itself that rational beings in the world should at the same time be worthy of happiness in conformity with the moral law and also possess this happiness proportionately. Now in respect of the first element of the summum bonum, namely, that which concerns morality, the moral law gives merely a command, and to doubt the possibility of that element would be the same as to call in question the moral law itself. But as regards the second element of that ob- ject, namely, happiness perfectly proportioned to that worthiness, it is true that there is no need of a command to admit its possibility in general, for theoretical reason has nothing to say against it; but the manner in which we have to conceive this harmony of the laws of nature with those of freedom has in it something in respect of which we have a choice, because theoretical reason decides nothing with apodeictic certainty about it, and in respect of this there may be a moral interest which turns the scale.
quite agree with him in this, in all cases where the want is founded on inclina- tion, which cannot necessarily postulate the existence of its object even for the man that is affected by it, much less can it contain a demand valid for everyone, and therefore it is merely a subjective ground of the wish. But in the present case we have a want of reason springing from an objective determining principle of the will, namely, the moral law, which necessarily binds every rational being, and therefore justifies him in assuming a priori in nature the conditions proper for it, and makes the latter inseparable from the complete practical use of reason. It is a duty to realize the summum bonum to the utmost of our power, therefore it must be possible, consequently it is unavoidable for every rational being in the world to assume what is necessary for its objective possibility. The assumption is as necessary as the moral law, in connection with which alone it is valid.
146
? I had said above that in a mere course of nature in the world an accurate correspondence between happiness and moral worth is not to be expected and must be regarded as impossible, and that there- fore the possibility of the summum bonum cannot be admitted from this side except on the supposition of a moral Author of the world. I purposely reserved the restriction of this judgement to the subjec- tive conditions of our reason, in order not to make use of it until the manner of this belief should be defined more precisely. The fact is that the impossibility referred to is merely subjective, that is, our reason finds it impossible for it to render conceivable in the way of a mere course of nature a connection so exactly proportioned and so thoroughly adapted to an end, between two sets of events hap- pening according to such distinct laws; although, as with every- thing else in nature that is adapted to an end, it cannot prove, that is, show by sufficient objective reason, that it is not possible by uni- versal laws of nature.
Now, however, a deciding principle of a different kind comes into play to turn the scale in this uncertainty of speculative reason. The command to promote the summum bonum is established on an objective basis (in practical reason); the possibility of the same in general is likewise established on an objective basis (in theoretical reason, which has nothing to say against it). But reason cannot de- cide objectively in what way we are to conceive this possibility; whether by universal laws of nature without a wise Author presid- ing over nature, or only on supposition of such an Author. Now here there comes in a subjective condition of reason, the only way theoretically possible for it, of conceiving the exact harmony of the kingdom of nature with the kingdom of morals, which is the condi- tion of the possibility of the summum bonum; and at the same time the only one conducive to morality (which depends on an objective law of reason). Now since the promotion of this summum bonum, and therefore the supposition of its possibility, are objectively nec- essary (though only as a result of practical reason), while at the same time the manner in which we would conceive it rests with our own choice, and in this choice a free interest of pure practical reason decides for the assumption of a wise Author of the world; it is clear that the principle that herein determines our judgement, though as
Immanuel Kant
147
The Critique of Practical Reason
a want it is subjective, yet at the same time being the means of promoting what is objectively (practically) necessary, is the founda- tion of a maxim of belief in a moral point of view, that is, a faith of pure practical reason. This, then, is not commanded, but being a voluntary determination of our judgement, conducive to the moral (commanded) purpose, and moreover harmonizing with the theo- retical requirement of reason, to assume that existence and to make it the foundation of our further employment of reason, it has itself sprung from the moral disposition of mind; it may therefore at times waver even in the well-disposed, but can never be reduced to unbe- lief.
IX. Of the Wise Adaptation of Man's Cognitive Faculties to his Practical Destination.
IF HUMAN NATURE is destined to endeavour after the summum bonum, we must suppose also that the measure of its cognitive fac- ulties, and particularly their relation to one another, is suitable to this end. Now the Critique of Pure Speculative Reason proves that this is incapable of solving satisfactorily the most weighty problems that are proposed to it, although it does not ignore the natural and important hints received from the same reason, nor the great steps that it can make to approach to this great goal that is set before it, which, however, it can never reach of itself, even with the help of the greatest knowledge of nature. Nature then seems here to have provided us only in a stepmotherly fashion with the faculty required for our end.
Suppose, now, that in this matter nature had conformed to our wish and had given us that capacity of discernment or that enlight- enment which we would gladly possess, or which some imagine they actually possess, what would in all probability be the conse- quence? Unless our whole nature were at the same time changed, our inclinations, which always have the first word, would first of all demand their own satisfaction, and, joined with rational reflection,
148
the greatest possible and most lasting satisfaction, under the name of happiness; the moral law would afterwards speak, in order to keep them within their proper bounds, and even to subject them all to a higher end, which has no regard to inclination. But instead of the conflict that the moral disposition has now to carry on with the inclinations, in which, though after some defeats, moral strength of mind may be gradually acquired, God and eternity with their awful majesty would stand unceasingly before our eyes (for what we can prove perfectly is to us as certain as that of which we are assured by the sight of our eyes). Transgression of the law, would, no doubt, be avoided; what is commanded would be done; but the mental dispo- sition, from which actions ought to proceed, cannot be infused by any command, and in this case the spur of action is ever active and external, so that reason has no need to exert itself in order to gather strength to resist the inclinations by a lively representation of the dignity of the law: hence most of the actions that conformed to the law would be done from fear, a few only from hope, and none at all from duty, and the moral worth of actions, on which alone in the eyes of supreme wisdom the worth of the person and even that of the world depends, would cease to exist. As long as the nature of man remains what it is, his conduct would thus be changed into mere mechanism, in which, as in a puppet-show, everything would gesticulate well, but there would be no life in the figures. Now, when it is quite otherwise with us, when with all the effort of our reason we have only a very obscure and doubtful view into the future, when the Governor of the world allows us only to conjecture his existence and his majesty, not to behold them or prove them clearly; and on the other hand, the moral law within us, without promising or threat- ening anything with certainty, demands of us disinterested respect; and only when this respect has become active and dominant, does it allow us by means of it a prospect into the world of the supersensible, and then only with weak glances: all this being so, there is room for true moral disposition, immediately devoted to the law, and a ratio- nal creature can become worthy of sharing in the summum bonum that corresponds to the worth of his person and not merely to his actions. Thus what the study of nature and of man teaches us suffi- ciently elsewhere may well be true here also; that the unsearchable

wisdom by which we exist is not less worthy of admiration in what it has denied than in what it has granted.

SECOND PART Methodology of Pure Practical Reason.
BY THE METHODOLOGY of pure practical reason we are not to under- stand the mode of proceeding with pure practical principles (whether in study or in exposition), with a view to a scientific knowledge of them, which alone is what is properly called method elsewhere in theoretical philosophy (for popular knowledge requires a manner, sci- ence a method, i. e. , a process according to principles of reason by which alone the manifold of any branch of knowledge can become a system). On the contrary, by this methodology is understood the mode in which we can give the laws of pure practical reason access to the human mind and influence on its maxims, that is, by which we can make the objectively practical reason subjectively practical also.
Now it is clear enough that those determining principles of the will which alone make maxims properly moral and give them a moral worth, namely, the direct conception of the law and the objective necessity of obeying it as our duty, must be regarded as the proper springs of actions, since otherwise legality of actions might be pro- duced, but not morality of character. But it is not so clear; on the contrary, it must at first sight seem to every one very improbable that even subjectively that exhibition of pure virtue can have more power over the human mind, and supply a far stronger spring even for effecting that legality of actions, and can produce more power- ful resolutions to prefer the law, from pure respect for it, to every other consideration, than all the deceptive allurements of pleasure or of all that may be reckoned as happiness, or even than all threatenings of pain and misfortune. Nevertheless, this is actually
Immanuel Kant
151
The Critique of Practical Reason
the case, and if human nature were not so constituted, no mode of presenting the law by roundabout ways and indirect recommenda- tions would ever produce morality of character. All would be simple hypocrisy; the law would be hated, or at least despised, while it was followed for the sake of one's own advantage. The letter of the law (legality) would be found in our actions, but not the spirit of it in our minds (morality); and as with all our efforts we could not quite free ourselves from reason in our judgement, we must inevitably appear in our own eyes worthless, depraved men, even though we should seek to compensate ourselves for this mortification before the inner tribunal, by enjoying the pleasure that a supposed natural or divine law might be imagined to have connected with it a sort of police machinery, regulating its operations by what was done with- out troubling itself about the motives for doing it.
It cannot indeed be denied that in order to bring an uncultivated or degraded mind into the track of moral goodness some prepara- tory guidance is necessary, to attract it by a view of its own advan- tage, or to alarm it by fear of loss; but as soon as this mechanical work, these leading-strings have produced some effect, then we must bring before the mind the pure moral motive, which, not only be- cause it is the only one that can be the foundation of a character (a practically consistent habit of mind with unchangeable maxims), but also because it teaches a man to feel his own dignity, gives the mind a power unexpected even by himself, to tear himself from all sensible attachments so far as they would fain have the rule, and to find a rich compensation for the sacrifice he offers, in the indepen- dence of his rational nature and the greatness of soul to which he sees that he is destined. We will therefore show, by such observa- tions as every one can make, that this property of our minds, this receptivity for a pure moral interest, and consequently the moving force of the pure conception of virtue, when it is properly applied to the human heart, is the most powerful spring and, when a contin- ued and punctual observance of moral maxims is in question, the only spring of good conduct. It must, however, be remembered that if these observations only prove the reality of such a feeling, but do not show any moral improvement brought about by it, this is no argument against the only method that exists of making the objec-
152
tively practical laws of pure reason subjectively practical, through the mere force of the conception of duty; nor does it prove that this method is a vain delusion. For as it has never yet come into vogue, experience can say nothing of its results; one can only ask for proofs of the receptivity for such springs, and these I will now briefly present, and then sketch the method of founding and cultivating genuine moral dispositions.
When we attend to the course of conversation in mixed compa- nies, consisting not merely of learned persons and subtle reasoners, but also of men of business or of women, we observe that, besides story-telling and jesting, another kind of entertainment finds a place in them, namely, argument; for stories, if they are to have novelty and interest, are soon exhausted, and jesting is likely to become insipid. Now of all argument there is none in which persons are more ready to join who find any other subtle discussion tedious, none that brings more liveliness into the company, than that which concerns the moral worth of this or that action by which the char- acter of some person is to be made out. Persons, to whom in other cases anything subtle and speculative in theoretical questions is dry and irksome, presently join in when the question is to make out the moral import of a good or bad action that has been related, and they display an exactness, a refinement, a subtlety, in excogitating everything that can lessen the purity of purpose, and consequently the degree of virtue in it, which we do not expect from them in any other kind of speculation. In these criticisms, persons who are pass- ing judgement on others often reveal their own character: some, in exercising their judicial office, especially upon the dead, seem in- clined chiefly to defend the goodness that is related of this or that deed against all injurious charges of insincerity, and ultimately to defend the whole moral worth of the person against the reproach of dissimulation and secret wickedness; others, on the contrary, turn their thoughts more upon attacking this worth by accusation and fault finding. We cannot always, however, attribute to these latter the intention of arguing away virtue altogether out of all human examples in order to make it an empty name; often, on the con- trary, it is only well-meant strictness in determining the true moral import of actions according to an uncompromising law.

son with such a law, instead of with examples, lowers self-conceit in moral matters very much, and not merely teaches humility, but makes every one feel it when he examines himself closely. Nevertheless, we can for the most part observe, in those who defend the purity of purpose in giving examples that where there is the presumption of uprightness they are anxious to remove even the least spot, lest, if all examples had their truthfulness disputed, and if the purity of all human virtue were denied, it might in the end be regarded as a mere phantom, and so all effort to attain it be made light of as vain affectation and delusive conceit.
I do not know why the educators of youth have not long since made use of this propensity of reason to enter with pleasure upon the most subtle examination of the practical questions that are thrown up; and why they have not, after first laying the foundation of a purely moral catechism, searched through the biographies of an- cient and modern times with the view of having at hand instances of the duties laid down, in which, especially by comparison of simi- lar actions under different circumstances, they might exercise the critical judgement of their scholars in remarking their greater or less moral significance. This is a thing in which they would find that even early youth, which is still unripe for speculation of other kinds, would soon Become very acute and not a little interested, because it feels the progress of its faculty of judgement; and, what is most important, they could hope with confidence that the frequent prac- tice of knowing and approving good conduct in all its purity, and on the other hand of remarking with regret or contempt the least deviation from it, although it may be pursued only as a sport in which children may compete with one another, yet will leave a last- ing impression of esteem on the one hand and disgust on the other; and so, by the mere habit of looking on such actions as deserving approval or blame, a good foundation would be laid for uprightness in the future course of life. Only I wish they would spare them the example of so-called noble (supermeritorious) actions, in which our sentimental books so much abound, and would refer all to duty merely, and to the worth that a man can and must give himself in his own eyes by the consciousness of not having transgressed it, since whatever runs up into empty wishes and longings after inac-
154
cessible perfection produces mere heroes of romance, who, while they pique themselves on their feeling for transcendent greatness, release themselves in return from the observance of common and every-day obligations, which then seem to them petty and insignifi- cant. *
But if it is asked: "What, then, is really pure morality, by which as a touchstone we must test the moral significance of every action," then I must admit that it is only philosophers that can make the decision of this question doubtful, for to common sense it has been decided long ago, not indeed by abstract general formulae, but by habitual use, like the distinction between the right and left hand. We will then point out the criterion of pure virtue in an example first, and, imagining that it is set before a boy, of say ten years old, for his judgement, we will see whether he would necessarily judge so of himself without being guided by his teacher. Tell him the his- tory of an honest man whom men want to persuade to join the calumniators of an innocent and powerless person (say Anne Boleyn, accused by Henry VIII of England). He is offered advantages, great gifts, or high rank; he rejects them. This will excite mere approba- tion and applause in the mind of the hearer. Now begins the threat- ening of loss. Amongst these traducers are his best friends, who now renounce his friendship; near kinsfolk, who threaten to disinherit him (he being without fortune); powerful persons, who can perse- cute and harass him in all places and circumstances; a prince, who threatens him with loss of freedom, yea, loss of life. Then to fill the measure of suffering, and that he may feel the pain that only the morally good heart can feel very deeply, let us conceive his family threatened with extreme distress and want, entreating him to yield;
* It is quite proper to extol actions that display a great, unselfish, sympathizing mind or humanity. But, in this case, we must fix attention not so much on the elevation of soul, which is very fleeting and transitory, as on the subjection of the heart to duty, from which a more enduring impression may be expected, because this implies principle (whereas the former only implies ebullitions). One need only reflect a little and he will always find a debt that he has by some means incurred towards the human race (even if it were only this, by the inequality of men in the civil constitution, enjoys advantages on account of which others must be the more in want), which will prevent the thought of duty from being re- pressed by the self-complacent imagination of merit.
Immanuel Kant

The Critique of Practical Reason
conceive himself, though upright, yet with feelings not hard or in- sensible either to compassion or to his own distress; conceive him, I say, at the moment when he wishes that he had never lived to see the day that exposed him to such unutterable anguish, yet remain- ing true to his uprightness of purpose, without wavering or even doubting; then will my youthful hearer be raised gradually from mere approval to admiration, from that to amazement, and finally to the greatest veneration, and a lively wish that be himself could be such a man (though certainly not in such circumstances). Yet virtue is here worth so much only because it costs so much, not because it brings any profit. All the admiration, and even the endeavour to resemble this character, rest wholly on the purity of the moral prin- ciple, which can only be strikingly shown by removing from the springs of action everything that men may regard as part of happi- ness. Morality, then, must have the more power over the human heart the more purely it is exhibited. Whence it follows that, if the law of morality and the image of holiness and virtue are to exercise any influence at all on our souls, they can do so only so far as they are laid to heart in their purity as motives, unmixed with any view to prosperity, for it is in suffering that they display themselves most nobly. Now that whose removal strengthens the effect of a moving force must have been a hindrance, consequently every admixture of motives taken from our own happiness is a hindrance to the influ- ence of the moral law on the heart. I affirm further that even in that admired action, if the motive from which it was done was a high regard for duty, then it is just this respect for the law that has the greatest influence on the mind of the spectator, not any pretension to a supposed inward greatness of mind or noble meritorious senti- ments; consequently duty, not merit, must have not only the most definite, but, when it is represented in the true light of its inviolabil- ity, the most penetrating, influence on the mind.
It is more necessary than ever to direct attention to this method in our times, when men hope to produce more effect on the mind with soft, tender feelings, or high-flown, puffing-up pretensions, which rather wither the heart than strengthen it, than by a plain and earnest representation of duty, which is more suited to human imperfection and to progress in goodness. To set before children, as
156
a pattern, actions that are called noble, magnanimous, meritorious, with the notion of captivating them by infusing enthusiasm for such actions, is to defeat our end. For as they are still so backward in the observance of the commonest duty, and even in the correct estima- tion of it, this means simply to make them fantastical romancers betimes. But, even with the instructed and experienced part of man- kind, this supposed spring has, if not an injurious, at least no genu- ine, moral effect on the heart, which, however, is what it was de- sired to produce.
All feelings, especially those that are to produce unwonted exer- tions, must accomplish their effect at the moment they are at their height and before the calm down; otherwise they effect nothing; for as there was nothing to strengthen the heart, but only to excite it, it naturally returns to its normal moderate tone and, thus, falls back into its previous languor. Principles must be built on conceptions; on any other basis there can only be paroxysms, which can give the person no moral worth, nay, not even confidence in himself, with- out which the highest good in man, consciousness of the morality of his mind and character, cannot exist. Now if these conceptions are to become subjectively practical, we must not rest satisfied with admiring the objective law of morality, and esteeming it highly in reference to humanity, but we must consider the conception of it in relation to man as an individual, and then this law appears in a form indeed that is highly deserving of respect, but not so pleasant as if it belonged to the element to which he is naturally accustomed; but on the contrary as often compelling him to quit this element, not without self-denial, and to betake himself to a higher, in which he can only maintain himself with trouble and with unceasing appre- hension of a relapse. In a word, the moral law demands obedience, from duty not from predilection, which cannot and ought not to be presupposed at all.
Let us now see, in an example, whether the conception of an ac- tion, as a noble and magnanimous one, has more subjective moving power than if the action is conceived merely as duty in relation to the solemn law of morality. The action by which a man endeavours at the greatest peril of life to rescue people from shipwreck, at last losing his life in the attempt, is reckoned on one side as duty, but on
Immanuel Kant
157
The Critique of Practical Reason
the other and for the most part as a meritorious action, but our esteem for it is much weakened by the notion of duty to himself which seems in this case to be somewhat infringed. More decisive is the magnanimous sacrifice of life for the safety of one's country; and yet there still remains some scruple whether it is a perfect duty to devote one's self to this purpose spontaneously and unbidden, and the action has not in itself the full force of a pattern and im- pulse to imitation. But if an indispensable duty be in question, the transgression of which violates the moral law itself, and without regard to the welfare of mankind, and as it were tramples on its holiness (such as are usually called duties to God, because in Him we conceive the ideal of holiness in substance), then we give our most perfect esteem to the pursuit of it at the sacrifice of all that can have any value for the dearest inclinations, and we find our soul strengthened and elevated by such an example, when we convince ourselves by contemplation of it that human nature is capable of so great an elevation above every motive that nature can oppose to it. Juvenal describes such an example in a climax which makes the reader feel vividly the force of the spring that is contained in the pure law of duty, as duty:
Esto bonus miles, tutor bonus, arbiter idem Integer; ambiguae si quando citabere testis Incertaeque rei, Phalaris licet imperet ut sis Falsus, et admoto dictet periuria tauro, Summum crede nefas animam praeferre pudori, Et propter vitam vivendi perdere causas. *
When we can bring any flattering thought of merit into our ac- tion, then the motive is already somewhat alloyed with self-love and has therefore some assistance from the side of the sensibility. But to postpone everything to the holiness of duty alone, and to be con-
* [Juvenal, Satirae, "Be you a good soldier, a faithful tutor, an uncorrupted um- pire also; if you are summoned as a witness in a doubtful and uncertain thing, though Phalaris should command that you should be false, and should dictate perjuries with the bull brought to you, believe it the highest impiety to prefer life to reputation, and for the sake of life, to lose the causes of living. "]
158
? scious that we can because our own reason recognises this as its command and says that we ought to do it, this is, as it were, to raise ourselves altogether above the world of sense, and there is insepara- bly involved in the same a consciousness of the law, as a spring of a faculty that controls the sensibility; and although this is not always attended with effect, yet frequent engagement with this spring, and the at first minor attempts at using it, give hope that this effect may be wrought, and that by degrees the greatest, and that a purely moral interest in it may be produced in us.
The method then takes the following course. At first we are only concerned to make the judging of actions by moral laws a natural employment accompanying all our own free actions, as well as the observation of those of others, and to make it as it were a habit, and to sharpen this judgement, asking first whether the action conforms objectively to the moral law, and to what law; and we distinguish the law that merely furnishes a principle of obligation from that which is really obligatory (leges obligandi a legibus obligantibus); as, for instance, the law of what men's wants require from me, as contrasted with that which their rights demand, the latter of which prescribes essential, the former only non-essential duties; and thus we teach how to distinguish different kinds of duties which meet in the same action. The other point to which attention must be di- rected is the question whether the action was also (subjectively) done for the sake of the moral law, so that it not only is morally correct as a deed, but also, by the maxim from which it is done, has moral worth as a disposition. Now there is no doubt that this practice, and the resulting culture of our reason in judging merely of the practi- cal, must gradually produce a certain interest even in the law of reason, and consequently in morally good actions. For we ultimately take a liking for a thing, the contemplation of which makes us feel that the use of our cognitive faculties is extended; and this exten- sion is especially furthered by that in which we find moral correct- ness, since it is only in such an order of things that reason, with its faculty of determining a priori on principle what ought to be done, can find satisfaction. An observer of nature takes liking at last to objects that at first offended his senses, when he discovers in them the great adaptation of their organization to design, so that his rea-

son finds food in its contemplation. So Leibnitz spared an insect that he had carefully examined with the microscope, and replaced it on its leaf, because he had found himself instructed by the view of it and had, as it were, received a benefit from it.
But this employment of the faculty of judgement, which makes us feel our own cognitive powers, is not yet the interest in actions and in their morality itself. It merely causes us to take pleasure in engaging in such criticism, and it gives to virtue or the disposition that conforms to moral laws a form of beauty, which is admired, but not on that account sought after (laudatur et alget); as every- thing the contemplation of which produces a consciousness of the harmony of our powers of conception, and in which we feel the whole of our faculty of knowledge (understanding and imagina- tion) strengthened, produces a satisfaction, which may also be com- municated to others, while nevertheless the existence of the object remains indifferent to us, being only regarded as the occasion of our becoming aware of the capacities in us which are elevated above mere animal nature. Now, however, the second exercise comes in, the living exhibition of morality of character by examples, in which attention is directed to purity of will, first only as a negative perfec- tion, in so far as in an action done from duty no motives of inclina- tion have any influence in determining it. By this the pupil's atten- tion is fixed upon the consciousness of his freedom, and although this renunciation at first excites a feeling of pain, nevertheless, by its withdrawing the pupil from the constraint of even real wants, there is proclaimed to him at the same time a deliverance from the mani- fold dissatisfaction in which all these wants entangle him, and the mind is made capable of receiving the sensation of satisfaction from other sources. The heart is freed and lightened of a burden that always secretly presses on it, when instances of pure moral resolu- tions reveal to the man an inner faculty of which otherwise he has no right knowledge, the inward freedom to release himself from the boisterous importunity of inclinations, to such a degree that none of them, not even the dearest, shall have any influence on a resolu- tion, for which we are now to employ our reason. Suppose a case where I alone know that the wrong is on my side, and although a free confession of it and the offer of satisfaction are so strongly op-
160
posed by vanity, selfishness, and even an otherwise not illegitimate antipathy to the man whose rights are impaired by me, I am never- theless able to discard all these considerations; in this there is im- plied a consciousness of independence on inclinations and circum- stances, and of the possibility of being sufficient for myself, which is salutary to me in general for other purposes also. And now the law of duty, in consequence of the positive worth which obedience to it makes us feel, finds easier access through the respect for our- selves in the consciousness of our freedom. When this is well estab- lished, when a man dreads nothing more than to find himself, on self-examination, worthless and contemptible in his own eyes, then every good moral disposition can be grafted on it, because this is the best, nay, the only guard that can keep off from the mind the pres- sure of ignoble and corrupting motives.
I have only intended to point out the most general maxims of the methodology of moral cultivation and exercise. As the manifold variety of duties requires special rules for each kind, and this would be a prolix affair, I shall be readily excused if in a work like this, which is only preliminary, I content myself with these outlines.

TWO THINGS FILL the mind with ever new and increasing admiration and awe, the oftener and the more steadily we reflect on them: the starry heavens above and the moral law within. I have not to search for them and conjecture them as though they were veiled in dark- ness or were in the transcendent region beyond my horizon; I see them before me and connect them directly with the consciousness of my existence. The former begins from the place I occupy in the external world of sense, and enlarges my connection therein to an unbounded extent with worlds upon worlds and systems of sys- tems, and moreover into limitless times of their periodic motion, its beginning and continuance. The second begins from my invisible self, my personality, and exhibits me in a world which has true in- finity, but which is traceable only by the understanding, and with which I discern that I am not in a merely contingent but in a uni- versal and necessary connection, as I am also thereby with all those visible worlds. The former view of a countless multitude of worlds annihilates as it were my importance as an animal creature, which after it has been for a short time provided with vital power, one knows not how, must again give back the matter of which it was formed to the planet it inhabits (a mere speck in the universe). The second, on the contrary, infinitely elevates my worth as an intelli- gence by my personality, in which the moral law reveals to me a life independent of animality and even of the whole sensible world, at least so far as may be inferred from the destination assigned to my existence by this law, a destination not restricted to conditions and limits of this life, but reaching into the infinite.
But though admiration and respect may excite to inquiry, they 162
cannot supply the want of it. What, then, is to be done in order to enter on this in a useful manner and one adapted to the loftiness of the subject? Examples may serve in this as a warning and also for imitation. The contemplation of the world began from the noblest spectacle that the human senses present to us, and that our under- standing can bear to follow in their vast reach; and it ended- in astrology. Morality began with the noblest attribute of human na- ture, the development and cultivation of which give a prospect of infinite utility; and ended- in fanaticism or superstition. So it is with all crude attempts where the principal part of the business de- pends on the use of reason, a use which does not come of itself, like the use of the feet, by frequent exercise, especially when attributes are in question which cannot be directly exhibited in common ex- perience. But after the maxim had come into vogue, though late, to examine carefully beforehand all the steps that reason purposes to take, and not to let it proceed otherwise than in the track of a previ- ously well considered method, then the study of the structure of the universe took quite a different direction, and thereby attained an incomparably happier result. The fall of a stone, the motion of a sling, resolved into their elements and the forces that are manifested in them, and treated mathematically, produced at last that clear and henceforward unchangeable insight into the system of the world which, as observation is continued, may hope always to extend it- self, but need never fear to be compelled to retreat.
This example may suggest to us to enter on the same path in treating of the moral capacities of our nature, and may give us hope of a like good result. We have at hand the instances of the moral judgement of reason. By analysing these into their elementary con- ceptions, and in default of mathematics adopting a process similar to that of chemistry, the separation of the empirical from the ratio- nal elements that may be found in them, by repeated experiments on common sense, we may exhibit both pure, and learn with cer- tainty what each part can accomplish of itself, so as to prevent on the one hand the errors of a still crude untrained judgement, and on the other hand (what is far more necessary) the extravagances of genius, by which, as by the adepts of the philosopher's stone, with- out any methodical study or knowledge of nature, visionary trea-

sures are promised and the true are thrown away. In one word, sci- ence (critically undertaken and methodically directed) is the nar- row gate that leads to the true doctrine of practical wisdom, if we understand by this not merely what one ought to do, but what ought to serve teachers as a guide to construct well and clearly the road to wisdom which everyone should travel, and to secure others from going astray. Philosophy must always continue to be the guardian of this science; and although the public does not take any interest in its subtle investigations, it must take an interest in the resulting doctrines, which such an examination first puts in a clear light.

PREFACE
IF THERE EXISTS on any subject a philosophy (that is, a system of rational knowledge based on concepts), then there must also be for this philosophy a system of pure rational concepts, independent of any condition of intuition, in other words, a metaphysic. It may be asked whether metaphysical elements are required also for every practical philosophy, which is the doctrine of duties, and therefore also for Ethics, in order to be able to present it as a true science
Immanuel Kant

The Metaphysical Elements of Ethics
(systematically), not merely as an aggregate of separate doctrines (fragmentarily). As regards pure jurisprudence, no one will ques- tion this requirement; for it concerns only what is formal in the elective will, which has to be limited in its external relations accord- ing to laws of freedom; without regarding any end which is the matter of this will. Here, therefore, deontology is a mere scientific doctrine (doctrina scientiae). *
Now in this philosophy (of ethics) it seems contrary to the idea of it that we should go back to metaphysical elements in order to make the notion of duty purified from everything empirical (from every feeling) a motive of action. For what sort of notion can we form of the mighty power and herculean strength which would be sufficient to overcome the vice-breeding inclinations, if Virtue is to borrow her "arms from the armoury of metaphysics," which is a matter of speculation that only few men can handle? Hence all ethical teach- ing in lecture rooms, pulpits, and popular books, when it is decked out with fragments of metaphysics, becomes ridiculous. But it is not, therefore, useless, much less ridiculous, to trace in metaphysics the first principles of ethics; for it is only as a philosopher that any- one can reach the first principles of this conception of duty, other- wise we could not look for either certainty or purity in the ethical teaching. To rely for this reason on a certain feeling which, on ac- count of the effect expected from it, is called moral, may, perhaps,
*One who is acquainted with practical philosophy is not, therefore, a prac- tical philosopher. The latter is he who makes the rational end the prin- ciple of his actions, while at the same time he joins with this the necessary knowledge which, as it aims at action, must not be spun out into the most subtile threads of metaphysic, unless a legal duty is in question; in which case meum and tuum must be accurately determined in the balance of jus- tice, on the principle of equality of action and action, which requires some- thing like mathematical proportion, but not in the case of a mere ethical duty. For in this case the question is not only to know what it is a duty to do (a thing which on account of the ends that all men naturally have can be easily decided), but the chief point is the inner principle of the will namely that the consciousness of this duty be also the spring of action, in order that we may be able to say of the man who joins to his knowledge this principle of wisdom that he is a practical philosopher.
166
? even satisfy the popular teacher, provided he desires as the criterion of a moral duty to consider the problem: "If everyone in every case made your maxim the universal law, how could this law be consis- tent with itself? " But if it were merely feeling that made it our duty to take this principle as a criterion, then this would not be dictated by reason, but only adopted instinctively and therefore blindly.
But in fact, whatever men imagine, no moral principle is based on any feeling, but such a principle is really nothing else than an ob- scurely conceived metaphysic which inheres in every man's reason- ing faculty; as the teacher will easily find who tries to catechize his pupils in the Socratic method about the imperative of duty and its application to the moral judgement of his actions. The mode of stating it need not be always metaphysical, and the language need not necessarily be scholastic, unless the pupil is to be trained to be a philosopher. But the thought must go back to the elements of meta- physics, without which we cannot expect any certainty or purity, or even motive power in ethics.
If we deviate from this principle and begin from pathological, or purely sensitive, or even moral feeling (from what is subjectively practical instead of what is objective), that is, from the matter of the will, the end, not from its form that is the law, in order from thence to determine duties; then, certainly, there are no metaphysical ele- ments of ethics, for feeling by whatever it may be excited is always physical. But then ethical teaching, whether in schools, or lecture- rooms, etc. , is corrupted in its source. For it is not a matter of indif- ference by what motives or means one is led to a good purpose (the obedience to duty). However disgusting, then, metaphysics may appear to those pretended philosophers who dogmatize oracularly, or even brilliantly, about the doctrine of duty, it is, nevertheless, an indispensable duty for those who oppose it to go back to its prin- ciples even in ethics, and to begin by going to school on its benches.
We may fairly wonder how, after all previous explanations of the prin- ciples of duty, so far as it is derived from pure reason, it was still possible to reduce it again to a doctrine of happiness; in such a way, however, that a certain moral happiness not resting on empirical causes was ultimately arrived at, a self-contradictory nonentity. In fact, when
Immanuel Kant

The Metaphysical Elements of Ethics
the thinking man has conquered the temptations to vice, and is con- scious of having done his (often hard) duty, he finds himself in a state of peace and satisfaction which may well be called happiness, in which virtue is her own reward. Now, says the eudaemonist, this delight, this happiness, is the real motive of his acting virtuously. The notion of duty, says be, does not immediately determine his will; it is only by means of the happiness in prospect that he is moved to his duty. Now, on the other hand, since he can promise himself this reward of virtue only from the consciousness of having done his duty, it is clear that the latter must have preceded: that is, be must feel himself bound to do his duty before he thinks, and without thinking, that happiness will be the consequence of obedience to duty. He is thus involved in a circle in his assignment of cause and effect. He can only hope to be happy if he is conscious of his obedience to duty: and he can only be moved to obedience to duty if be foresees that he will thereby become happy. But in this reasoning there is also a contradiction. For, on the one side, he must obey his duty, without asking what effect this will have on his happiness, consequently, from a moral principle; on the other side, he can only recognize something as his duty when he can reckon on happiness which will accrue to him thereby, and conse- quently on a pathological principle, which is the direct opposite of the former.
I have in another place (the Berlin Monatsschrift), reduced, as I believe, to the simplest expressions the distinction between patho- logical and moral pleasure. The pleasure, namely, which must pre- cede the obedience to the law in order that one may act according to the law is pathological, and the process follows the physical order of nature; that which must be preceded by the law in order that it may be felt is in the moral order. If this distinction is not observed; if eudaemonism (the principle of happiness) is adopted as the prin- ciple instead of eleutheronomy (the principle of freedom of the in- ner legislation), the consequence is the euthanasia (quiet death) of all morality.
The cause of these mistakes is no other than the following: Those who are accustomed only to physiological explanations will not ad- mit into their heads the categorical imperative from which these
168
laws dictatorially proceed, notwithstanding that they feel themselves irresistibly forced by it. Dissatisfied at not being able to explain what lies wholly beyond that sphere, namely, freedom of the elective will, elevating as is this privilege, that man has of being capable of such an idea. They are stirred up by the proud claims of speculative rea- son, which feels its power so strongly in the fields, just as if they were allies leagued in defence of the omnipotence of theoretical rea- son and roused by a general call to arms to resist that idea; and thus they are at present, and perhaps for a long time to come, though ultimately in vain, to attack the moral concept of freedom and if possible render it doubtful.

INTRODUCTION
INTRODUCTION TO THE METAPHYSICAL ELE- MENTS OF ETHICS
ETHICS in ancient times signified moral philosophy (philosophia moral is) generally, which was also called the doctrine of duties. Subsequently it was found advisable to confine this name to a part of moral philosophy, namely, to the doctrine of duties which are not subject to external laws (for which in German the name Tugendlehre was found suitable). Thus the system of general deon- tology is divided into that of jurisprudence (jurisprudentia), which is capable of external laws, and of ethics, which is not thus capable, and we may let this division stand.
I. Exposition of the Conception of Ethics
The notion of duty is in itself already the notion of a constraint of the free elective will by the law; whether this constraint be an exter- nal one or be self-constraint. The moral imperative, by its categori- cal (the unconditional ought) announces this constraint, which there- fore does not apply to all rational beings (for there may also be holy beings), but applies to men as rational physical beings who are un- holy enough to be seduced by pleasure to the transgression of the moral law, although they themselves recognize its authority; and when they do obey it, to obey it unwillingly (with resistance of their inclination); and it is in this that the constraint properly consists. *
*Man, however, as at the same time a moral being, when he considers himself objectively, which he is qualified to do by his pure practical rea- son, (i. e. , according to humanity in his own person). finds himself holy
170
? Now, as man is a free (moral) being, the notion of duty can contain only self-constraint (by the idea of the law itself ), when we look to the internal determination of the will (the spring), for thus only is it possible to combine that constraint (even if it were external) with the freedom of the elective will. The notion of duty then must be an ethical one.
The impulses of nature, then, contain hindrances to the fulfilment of duty in the mind of man, and resisting forces, some of them powerful; and he must judge himself able to combat these and to conquer them by means of reason, not in the future, but in the present, simultaneously with the thought; he must judge that he can do what the law unconditionally commands that be ought.
Now the power and resolved purpose to resist a strong but unjust opponent is called fortitude (fortitudo), and when concerned with the opponent of the moral character within us, it is virtue (virtus, fortitudo moralis). Accordingly, general deontology, in that part which brings not external, but internal, freedom under laws is the doctrine of virtue.
Jurisprudence had to do only with the formal condition of exter- nal freedom (the condition of consistency with itself, if its maxim became a universal law), that is, with law. Ethics, on the contrary, supplies us with a matter (an object of the free elective will), an end of pure reason which is at the same time conceived as an ob- jectively necessary end, i. e. , as duty for all men. For, as the sen- sible inclinations mislead us to ends (which are the matter of the elective will) that may contradict duty, the legislating reason can-
enough to transgress the law only unwillingly; for there is no man so depraved who in this transgression would not feel a resistance and an abhorrence of himself, so that he must put a force on himself. It is impos- sible to explain the phenomenon that at this parting of the ways (where the beautiful fable places Hercules between virtue and sensuality) man shows more propensity to obey inclination than the law. For, we can only explain what happens by tracing it to a cause according to physical laws; but then we should not be able to conceive the elective will as free. Now this mutually opposed self-constraint and the inevitability of it makes us recognize the incomprehensible property of freedom.
Immanuel Kant

The Metaphysical Elements of Ethics
not otherwise guard against their influence than by an opposite moral end, which therefore must be given a priori independently on inclination.
An end is an object of the elective will (of a rational being) by the idea of which this will is determined to an action for the production of this object. Now I may be forced by others to actions which are directed to an end as means, but I cannot be forced to have an end; I can only make something an end to myself. If, however, I am also bound to make something which lies in the notions of practical reason an end to myself, and there- fore besides the formal determining principle of the elective will (as contained in law) to have also a material principle, an end which can be opposed to the end derived from sensible impulses; then this gives the notion of an end which is in itself a duty. The doctrine of this cannot belong to jurisprudence, but to ethics, since this alone includes in its conception self-constraint accord- ing to moral laws.
For this reason, ethics may also be defined as the system of the ends of the pure practical reason. The two parts of moral philoso- phy are distinguished as treating respectively of ends and of duties of constraint. That ethics contains duties to the observance of which one cannot be (physically) forced by others, is merely the conse- quence of this, that it is a doctrine of ends, since to be forced to have ends or to set them before one's self is a contradiction.
Now that ethics is a doctrine of virtue (doctrina officiorum virtutis) follows from the definition of virtue given above com- pared with the obligation, the peculiarity of which has just been shown. There is in fact no other determination of the elective will, except that to an end, which in the very notion of it implies that I cannot even physically be forced to it by the elective will of oth- ers. Another may indeed force me to do something which is not my end (but only means to the end of another), but he cannot force me to make it my own end, and yet I can have no end except of my own making. The latter supposition would be a contradic- tion- an act of freedom which yet at the same time would not be free. But there is no contradiction in setting before one's self an end which is also a duty: for in this case I constrain myself, and
172
this is quite consistent with freedom. * But how is such an end possible? That is now the question. For the possibility of the no- tion of the thing (viz. , that it is not self-contradictory) is not enough to prove the possibility of the thing itself (the objective reality of the notion).
II. Exposition of the Notion of an End which is also a Duty
We can conceive the relation of end to duty in two ways; either starting from the end to find the maxim of the dutiful actions; or conversely, setting out from this to find the end which is also duty. jurisprudence proceeds in the former way. It is left to everyone's free elective will what end he will choose for his action. But its maxim is determined a priori; namely, that the freedom of the agent must be consistent with the free- dom of every other according to a universal law.
Ethics, however, proceeds in the opposite way. It cannot start from the ends which the man may propose to himself, and hence give directions as to the maxims he should adopt, that is, as to his duty; for that would be to take empirical principles of maxims, and these could not give any notion of duty; since this, the categorical ought, has its root in pure reason alone. Indeed, if the maxims were to be adopted in accordance with those ends (which are all selfish), we could not properly speak of the notion of duty at all. Hence in ethics the notion of duty must lead to ends, and must on moral principles give the foundation of maxims with respect to the ends which we ought to propose to ourselves.
*The less a man can be physically forced, and the more he can be morally forced (by the mere idea of duty), so much the freer he is. The man, for example, who is of sufficiently firm resolution and strong mind not to give up an enjoyment which he has resolved on, however much loss is shown as resulting therefrom, and who yet desists from his purpose unhesitatingly, though very reluctantly, when he finds that it would cause him to neglect an official duty or a sick father; this man proves his free- dom in the highest degree by this very thing, that he cannot resist the voice of duty.
Immanuel Kant

The Metaphysical Elements of Ethics
Setting aside the question what sort of end that is which is in itself a duty, and how such an end is possible, it is here only necessary to show that a duty of this kind is called a duty of virtue, and why it is so called.
To every duty corresponds a right of action (facultas moral is generatim), but all duties do not imply a corresponding right (facultas juridica) of another to compel any one, but only the duties called legal duties. Similarly to all ethical obligation corresponds the no- tion of virtue, but it does not follow that all ethical duties are duties of virtue. Those, in fact, are not so which do not concern so much a certain end (matter, object of the elective will), but merely that which is formal in the moral determination of the will (e. g. , that the duti- ful action must also be done from duty). It is only an end which is also duty that can be called a duty of virtue. Hence there are several of the latter kind (and thus there are distinct virtues); on the con- trary, there is only one duty of the former kind, but it is one which is valid for all actions (only one virtuous disposition).
The duty of virtue is essentially distinguished from the duty of justice in this respect; that it is morally possible to be externally compelled to the latter, whereas the former rests on free self-con- straint only. For finite holy beings (which cannot even be tempted to the violation of duty) there is no doctrine of virtue, but only moral philosophy, the latter being an autonomy of practical reason, whereas the former is also an autocracy of it. That is, it includes a consciousness- not indeed immediately perceived, but rightly con- cluded, from the moral categorical imperative- of the power to be- come master of one's inclinations which resist the law; so that hu- man morality in its highest stage can yet be nothing more than virtue; even if it were quite pure (perfectly free from the influence of a spring foreign to duty), a state which is poetically personified un- der the name of the wise man (as an ideal to which one should continually approximate).
Virtue, however, is not to be defined and esteemed merely as habit, and (as it is expressed in the prize essay of Cochius) as a long cus- tom acquired by practice of morally good actions. For, if this is not an effect of well-resolved and firm principles ever more and more purified, then, like any other mechanical arrangement brought about
174
by technical practical reason, it is neither armed for all circumstances nor adequately secured against the change that may be wrought by new allurements.
REMARK
To virtue = + a is opposed as its logical contradictory (contradictorie oppositum) the negative lack of virtue (moral weakness) = o; but vice = a is its contrary (contrarie s. realiter oppositum); and it is not merely a needless question but an offensive one to ask whether great crimes do not perhaps demand more strength of mind than great virtues. For by strength of mind we understand the strength of pur- pose of a man, as a being endowed with freedom, and consequently so far as he is master of himself (in his senses) and therefore in a healthy condition of mind. But great crimes are paroxysms, the very sight of which makes the man of healthy mind shudder. The ques- tion would therefore be something like this: whether a man in a fit of madness can have more physical strength than if he is in his senses; and we may admit this without on that account ascribing to him more strength of mind, if by mind we understand the vital principle of man in the free use of his powers. For since those crimes have their ground merely in the power of the inclinations that weaken reason, which does not prove strength of mind, this question would be nearly the same as the question whether a man in a fit of illness can show more strength than in a healthy condition; and this may be directly denied, since the want of health, which consists in the proper balance of all the bodily forces of the man, is a weakness in the system of these forces, by which system alone we can estimate absolute health.
Immanuel Kant

III. Of the Reason for conceiving an End which is also a Duty
An end is an object of the free elective will, the idea of which deter- mines this will to an action by which the object is produced. Ac- cordingly every action has its end, and as no one can have an end without himself making the object of his elective will his end, hence to have some end of actions is an act of the freedom of the agent, not an affect of physical nature. Now, since this act which deter- mines an end is a practical principle which commands not the means (therefore not conditionally) but the end itself (therefore uncondi- tionally), hence it is a categorical imperative of pure practical reason and one, therefore, which combines a concept of duty with that of an end in general.
Now there must be such an end and a categorical imperative cor- responding to it. For since there are free actions, there must also be ends to which as an object those actions are directed. Amongst these ends there must also be some which are at the same time (that is, by their very notion) duties. For if there were none such, then since no actions can be without an end, all ends which practical reason might have would be valid only as means to other ends, and a categorical imperative would be impossible; a supposition which destroys all moral philosophy.
Here, therefore, we treat not of ends which man actually makes to himself in accordance with the sensible impulses of his nature, but of objects of the free elective will under its own laws- objects which he ought to make his end. We may call the former technical (sub- jective), properly pragmatical, including the rules of prudence in the choice of its ends; but the latter we must call the moral (objec- tive) doctrine of ends. This distinction is, however, superfluous here, since moral philosophy already by its very notion is clearly sepa- rated from the doctrine of physical nature (in the present instance, anthropology). The latter resting on empirical principles, whereas the moral doctrine of ends which treats of duties rests on principles given a priori in pure practical reason.
