The Metaphysical Elements of Ethics
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 (systematically), not merely as an aggregate of separate doctrines (fragmentarily). As regards pure jurisprudence, no one will question this requirement; for it concerns only what is formal in the elective will, which has to be limited in its external relations according 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).1
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 teaching 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 anyone can reach the first principles of this conception of duty, otherwise we could not look for either certainty or purity in the ethical teaching. To rely for this reason on a certain feeling which, on account of the effect expected from it, is called moral, may, perhaps, 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 consistent 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.
{PREFACE ^paragraph 5}
But in fact, whatever men imagine, no moral principle is based on any feeling, but such a principle is really nothing else than an obscurely conceived metaphysic which inheres in every man's reasoning 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 metaphysics, 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 elements 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 indifference 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 principles even in ethics, and to begin by going to school on its benches.
We may fairly wonder how, after all previous explanations of the principles 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 the thinking man has conquered the temptations to vice, and is conscious 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, he 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 consequently 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 pathological and moral pleasure. The pleasure, namely, which must precede 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 principle instead of eleutheronomy (the principle of freedom of the inner legislation), the consequence is the euthanasia (quiet death) of all morality.
{PREFACE ^paragraph 10}
The cause of these mistakes is no other than the following: Those who are accustomed only to physiological explanations will not admit into their heads the categorical imperative from which these 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 reason, which feels its power so strongly in the fields, just as if they were allies leagued in defence of the omnipotence of theoretical reason 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 ELEMENTS OF ETHICS
Ethics in ancient times signified moral philosophy (philosophia moralis) 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 deontology 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 external one or be self-constraint. The moral imperative, by its categorical (the unconditional ought) announces this constraint, which therefore does not apply to all rational beings (for there may also be holy beings), but applies to men as rational physical beings who are unholy 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.2 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.
{INTRODUCTION ^paragraph 5}
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 he 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.
{INTRODUCTION ^paragraph 10}
Jurisprudence had to do only with the formal condition of external 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 objectively necessary end, i.e., as duty for all men. For, as the sensible inclinations mislead us to ends (which are the matter of the elective will) that may contradict duty, the legislating reason cannot 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 therefore 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 according 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 philosophy 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 consequence 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 compared 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 others. 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 contradiction- 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 this is quite consistent with freedom.3 But how is such an end possible? That is now the question. For the possibility of the notion 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 freedom of every other according to a universal law.
