The notion of duty stands in immediate relation to a law (even though I abstract from every end which is the matter of the law); as is shown by the formal principle of duty in the categorical imperative: "Act so that the maxims of thy action might become a universal law." But in ethics this is conceived as the law of thy own will, not of will in general, which might be that of others; for in the latter case it would give rise to a judicial duty which does not belong to the domain of ethics. In ethics, maxims are regarded as those subjective laws which merely have the specific character of universal legislation, which is only a negative principle (not to contradict a law in general). How, then, can there be further a law for the maxims of actions?

{INTRODUCTION ^paragraph 60}

It is the notion of an end which is also a duty, a notion peculiar to ethics, that alone is the foundation of a law for the maxims of actions; by making the subjective end (that which every one has) subordinate to the objective end (that which every one ought to make his own). The imperative: "Thou shalt make this or that thy end (e.

g., the happiness of others)" applies to the matter of the elective will (an object). Now since no free action is possible, without the agent having in view in it some end (as matter of his elective will), it follows that, if there is an end which is also a duty, the maxims of actions which are means to ends must contain only the condition of fitness for a possible universal legislation: on the other hand, the end which is also a duty can make it a law that we should have such a maxim, whilst for the maxim itself the possibility of agreeing with a universal legislation is sufficient.

For maxims of actions may be arbitrary, and are only limited by the condition of fitness for a universal legislation, which is the formal principle of actions. But a law abolishes the arbitrary character of actions, and is by this distinguished from recommendation (in which one only desires to know the best means to an end).

VII. Ethical Duties are of indeterminate, Juridical Duties of

strict, Obligation

{INTRODUCTION ^paragraph 65}

This proposition is a consequence of the foregoing; for if the law can only command the maxim of the actions, not the actions themselves, this is a sign that it leaves in the observance of it a lat.i.tude (lat.i.tudo) for the elective will; that is, it cannot definitely a.s.sign how and how much we should do by the action towards the end which is also duty. But by an indeterminate duty is not meant a permission to make exceptions from the maxim of the actions, but only the permission to limit one maxim of duty by another (e. g., the general love of our neighbour by the love of parents); and this in fact enlarges the field for the practice of virtue. The more indeterminate the duty, and the more imperfect accordingly the obligation of the man to the action, and the closer he nevertheless brings this maxim of obedience thereto (in his own mind) to the strict duty (of justice), so much the more perfect is his virtuous action.

Hence it is only imperfect duties that are duties of virtue. The fulfilment of them is merit (meritum) = + a; but their transgression is not necessarily demerit (demeritum) = - a, but only moral unworth = o, unless the agent made it a principle not to conform to those duties. The strength of purpose in the former case is alone properly called virtue [Tugend] (virtus); the weakness in the latter case is not vice (vitium), but rather only lack of virtue [Untugend], a want of moral strength (defectus moralis). (As the word Tugend is derived from taugen [to be good for something], Untugend by its etymology signifies good for nothing.) Every action contrary to duty is called transgression (peccatum). Deliberate transgression which has become a principle is what properly const.i.tutes what is called vice (vitium).

Although the conformity of actions to justice (i.e., to be an upright man) is nothing meritorious, yet the conformity of the maxim of such actions regarded as duties, that is, reverence for justice is meritorious. For by this the man makes the right of humanity or of men his own end, and thereby enlarges his notion of duty beyond that of indebtedness (officium debiti), since although another man by virtue of his rights can demand that my actions shall conform to the law, he cannot demand that the law shall also contain the spring of these actions. The same thing is true of the general ethical command, "Act dutifully from a sense of duty." To fix this disposition firmly in one's mind and to quicken it is, as in the former case, meritorious, because it goes beyond the law of duty in actions and makes the law in itself the spring.

But just for or reason, those duties also must be reckoned as of indeterminate obligation, in respect of which there exists a subjective principle which ethically rewards them; or to bring them as near as possible to the notion of a strict obligation, a principle of susceptibility of this reward according to the law of virtue; namely, a moral pleasure which goes beyond mere satisfaction with oneself (which may be merely negative), and of which it is proudly said that in this consciousness virtue is its own reward.

{INTRODUCTION ^paragraph 70}

When this merit is a merit of the man in respect of other men of promoting their natural ends, which are recognized as such by all men (making their happiness his own), we might call it the sweet merit, the consciousness of which creates a moral enjoyment in which men are by sympathy inclined to revel; whereas the bitter merit of promoting the true welfare of other men, even though they should not recognize it as such (in the case of the unthankful and ungrateful), has commonly no such reaction, but only produces a satisfaction with one's self, although in the latter case this would be even greater.

VIII. Exposition of the Duties of Virtue as Intermediate Duties

(1) OUR OWN PERFECTION as an end which is also a duty

{INTRODUCTION ^paragraph 75}

(a) Physical perfection; that is, cultivation of all our faculties generally for the promotion of the ends set before us by reason.

That this is a duty, and therefore an end in itself, and that the effort to effect this even without regard to the advantage that it secures us, is based, not on a conditional (pragmatic), but an unconditional (moral) imperative, may be seen from the following consideration. The power of proposing to ourselves an end is the characteristic of humanity (as distinguished from the brutes). With the end of humanity in our own person is therefore combined the rational will, and consequently the duty of deserving well of humanity by culture generally, by acquiring or advancing the power to carry out all sorts of possible ends, so far as this power is to be found in man; that is, it is a duty to cultivate the crude capacities of our nature, since it is by that cultivation that the animal is raised to man, therefore it is a duty in itself.

This duty, however, is merely ethical, that is, of indeterminate obligation. No principle of reason prescribes how far one must go in this effort (in enlarging or correcting his faculty of understanding, that is, in acquisition of knowledge or technical capacity); and besides the difference in the circ.u.mstances into which men may come makes the choice of the kind of employment for which he should cultivate his talent very arbitrary. Here, therefore, there is no law of reason for actions, but only for the maxim of actions, viz.: "Cultivate thy faculties of mind and body so as to be effective for all ends that may come in thy way, uncertain which of them may become thy own."

(b) Cultivation of Morality in ourselves. The greatest moral perfection of man is to do his duty, and that from duty (that the law be not only the rule but also the spring of his actions). Now at first sight this seems to be a strict obligation, and as if the principle of duty commanded not merely the legality of every action, but also the morality, i.e., the mental disposition, with the exactness and strictness of a law; but in fact the law commands even here only the maxim of the action, namely, that we should seek the ground of obligation, not in the sensible impulses (advantage or disadvantage), but wholly in the law; so that the action itself is not commanded. For it is not possible to man to see so far into the depth of his own heart that he could ever be thoroughly certain of the purity of his moral purpose and the sincerity of his mind even in one single action, although he has no doubt about the legality of it. Nay, often the weakness which deters a man from the risk of a crime is regarded by him as virtue (which gives the notion of strength). And how many there are who may have led a long blameless life, who are only fortunate in having escaped so many temptations.

How much of the element of pure morality in their mental disposition may have belonged to each deed remains hidden even from themselves.

Accordingly, this duty to estimate the worth of one's actions not merely by their legality, but also by their morality (mental disposition), is only of indeterminate obligation; the law does not command this internal action in the human mind itself, but only the maxim of the action, namely, that we should strive with all our power that for all dutiful actions the thought of duty should be of itself an adequate spring.

(2) HAPPINESS OF OTHERS as an end which is also a duty

{INTRODUCTION ^paragraph 80}

(a) Physical Welfare. Benevolent wishes may be unlimited, for they do not imply doing anything. But the case is more difficult with benevolent action, especially when this is to be done, not from friendly inclination (love) to others, but from duty, at the expense of the sacrifice and mortification of many of our appet.i.tes. That this beneficence is a duty results from this: that since our self-love cannot be separated from the need to be loved by others (to obtain help from them in case of necessity), we therefore make ourselves an end for others; and this maxim can never be obligatory except by having the specific character of a universal law, and consequently by means of a will that we should also make others our ends. Hence the happiness of others is an end that is also a duty.

I am only bound then to sacrifice to others a part of my welfare without hope of recompense: because it is my duty, and it is impossible to a.s.sign definite limits how far that may go. Much depends on what would be the true want of each according to his own feelings, and it must be left to each to determine this for himself.

For that one should sacrifice his own happiness, his true wants, in order to promote that of others, would be a self-contradictory maxim if made a universal law. This duty, therefore, is only indeterminate; it has a certain lat.i.tude within which one may do more or less without our being able to a.s.sign its limits definitely.

The law holds only for the maxims, not for definite actions.

(b) Moral well-being of others (salus moral is) also belongs to the happiness of others, which it is our duty to promote, but only a negative duty. The pain that a man feels from remorse of conscience, although its origin is moral, is yet in its operation physical, like grief, fear, and every other diseased condition. To take care that he should not be deservedly smitten by this inward reproach is not indeed my duty but his business; nevertheless, it is my duty to do nothing which by the nature of man might seduce him to that for which his conscience may hereafter torment him, that is, it is my duty not to give him occasion of stumbling. But there are no definite limits within which this care for the moral satisfaction of others must be kept; therefore it involves only an indeterminate obligation.

IX. What is a Duty of Virtue?

{INTRODUCTION ^paragraph 85}

Virtue is the strength of the man's maxim in his obedience to duty. All strength is known only by the obstacles that it can overcome; and in the case of virtue the obstacles are the natural inclinations which may come into conflict with the moral purpose; and as it is the man who himself puts these obstacles in the way of his maxims, hence virtue is not merely a self-constraint (for that might be an effort of one inclination to constrain another), but is also a constraint according to a principle of inward freedom, and therefore by the mere idea of duty, according to its formal law.

All duties involve a notion of necessitation by the law, and ethical duties involve a necessitation for which only an internal legislation is possible; juridical duties, on the other hand, one for which external legislation also is possible. Both, therefore, include the notion of constraint, either self-constraint or constraint by others. The moral power of the former is virtue, and the action springing from such a disposition (from reverence for the law) may be called a virtuous action (ethical), although the law expresses a juridical duty. For it is the doctrine of virtue that commands us to regard the rights of men as holy.

But it does not follow that everything the doing of which is virtue, is, properly speaking, a duty of virtue. The former may concern merely the form of the maxims; the latter applies to the matter of them, namely, to an end which is also conceived as duty. Now, as the ethical obligation to ends, of which there may be many, is only indeterminate, because it contains only a law for the maxim of actions, and the end is the matter (object) of elective will; hence there are many duties, differing according to the difference of lawful ends, which may be called duties of virtue (officia honestatis), just because they are subject only to free self-constraint, not to the constraint of other men, and determine the end which is also a duty.

Virtue, being a coincidence of the rational will, with every duty firmly settled in the character, is, like everything formal, only one and the same. But, as regards the end of actions, which is also duty, that is, as regards the matter which one ought to make an end, there may be several virtues; and as the obligation to its maxim is called a duty of virtue, it follows that there are also several duties of virtue.

{INTRODUCTION ^paragraph 90}

The supreme principle of ethics (the doctrine of virtue) is: "Act on a maxim, the ends of which are such as it might be a universal law for everyone to have." On this principle a man is an end to himself as well as others, and it is not enough that he is not permitted to use either himself or others merely as means (which would imply that be might be indifferent to them), but it is in itself a duty of every man to make mankind in general his end.

The principle of ethics being a categorical imperative does not admit of proof, but it admits of a justification from principles of pure practical reason. Whatever in relation to mankind, to oneself, and others, can be an end, that is an end for pure practical reason: for this is a faculty of a.s.signing ends in general; and to be indifferent to them, that is, to take no interest in them, is a contradiction; since in that case it would not determine the maxims of actions (which always involve an end), and consequently would cease to be practical reasons. Pure reason, however, cannot command any ends a priori, except so far as it declares the same to be also a duty, which duty is then cared a duty of virtue.
