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 a

INTRODUCTION TO THE METAPHYSICAL ELEMENTS OF ETHICS
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, wh

I. Exposition of the Conception of Ethics
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 t

II. Exposition of the Notion of an End which is also a Duty
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. INTRODUCTION ^pa

To virtue = + a is opposed as its logical contradictory (contradictorie oppositum) the negative lack of virtue (moral weakness) = 0; 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 purpose of a man, as a being endowed with freedom, and consequently so far as he is master of

III. Of the Reason for conceiving an End which is also a Duty
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 determines this will to an action by which the object is produced. Accordingly 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 determines an end is a practical principle which commands not the means (therefore not conditionally) b

They are: A. OUR OWN PERFECTION, B. HAPPINESS OF OTHERS. We cannot invert these and make on one side our own happiness, and on the other the perfection of others, ends which should be in themselves duties for the same person. INTRODUCTION ^paragraph 40 For one's own happiness is, no doubt, an end that all men have (by virtue of the impulse of their nature), but this end cannot without contradiction be regarded as a duty.

A. OUR OWN PERFECTION
A. OUR OWN PERFECTION
The word perfection is liable to many misconceptions. It is sometimes understood as a notion belonging to transcendental philosophy; viz., the notion of the totality of the manifold which taken together constitutes a thing; sometimes, again, it is understood as belonging to teleology, so that it signifies the correspondence of the properties of a thing to an end. Perfection in the former sense might be called quantitative (material), in the latter qualitative (formal) perfection. The former can

B. HAPPINESS OF OTHERS
It is inevitable for human nature that man a should wish and seek for happiness, that is, satisfaction with his condition, with certainty of the continuance of this satisfaction. But for this very reason it is not an end that is also a duty. Some writers still make a distinction between moral and physical happiness (the former consisting in satisfaction with one's person and moral behaviour, that is, with what one does; the other in satisfaction with that which nature confers, consequently with

VI. Ethics does not supply Laws for Actions (which is done by Jurisprudence), but only for the Maxims of Action
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.

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 latitude (latitudo) for the elective will; that is, it cannot definitely assign 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 p

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.

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 appetites. 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

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 constra

INTRODUCTION ^paragraph 95 That external constraint, so far as it withstands that which hinders the external freedom that agrees with general laws (as an obstacle of the obstacle thereto), can be consistent with ends generally, is clear on the principle of contradiction, and I need not go beyond the notion of freedom in order to see it, let the end which each may be what he will. Accordingly, the supreme principle of jurisprudence is an analytical principle. On the contrary the principle of ethi

INTRODUCTION ^paragraph 135 These are such moral qualities as, when a man does not possess them, he is not bound to acquire them. They are: the moral feeling, conscience, love of one's neighbour, and respect for ourselves (self-esteem). There is no obligation to have these, since they are subjective conditions of susceptibility for the notion of duty, not objective conditions of morality. They are all sensitive and antecedent, but natural capacities of mind (praedispositio) to be affected by not

A. THE MORAL FEELING
A. THE MORAL FEELING
This is the susceptibility for pleasure or displeasure, merely from the consciousness of the agreement or disagreement of our action with the law of duty. Now, every determination of the elective will proceeds from the idea of the possible action through the feeling of pleasure or displeasure in taking an interest in it or its effect to the deed; and here the sensitive state (the affection of the internal sense) is either a pathological or a moral feeling. The former is the feeling that precedes

B. OF CONSCIENCE
Similarly, conscience is not a thing to be acquired, and it is not a duty to acquire it; but every man, as a moral being, has it originally within him. To be bound to have a conscience would be as much as to say to be under a duty to recognize duties. For conscience is practical reason which, in every case of law, holds before a man his duty for acquittal or condemnation; consequently it does not refer to an object, but only to the subject (affecting the moral feeling by its own act); so that it

D. OF RESPECT
Respect (reverentia) is likewise something merely subjective; a feeling of a peculiar kind not a judgement about an object which it would be a duty to effect or to advance. For if considered as duty it could only be conceived as such by means of the respect which we have for it. To have a duty to this, therefore, would be as much as to say to be bound in duty to have a duty. When, therefore, it is said: "Man has a duty of self-esteem," this is improperly stated, and we ought rather to say: "The

INTRODUCTION ^paragraph 160 First. A duty can have only a single ground of obligation; and if two or more proof of it are adduced, this is a certain mark that either no valid proof has yet been given, or that there are several distinct duties which have been regarded as one. For all moral proofs, being philosophical, can only be drawn by means of rational knowledge from concepts, not like mathematics, through the construction of concepts.

INTRODUCTION ^paragraph 175 Virtue signifies a moral strength of will. But this does not exhaust the notion; for such strength might also belong to a holy (superhuman) being, in whom no opposing impulse counteracts the law of his rational will; who therefore willingly does everything in accordance with the law. Virtue then is the moral strength of a man's will in his obedience to duty; and this is a moral necessitation by his own law giving reason, inasmuch as this constitutes itself a power exe

XV. Of the Principle on which Ethics is separated from Jurisprudence
This separation on which the subdivision of moral philosophy in general rests, is founded on this: that the notion of freedom, which is common to both, makes it necessary to divide duties into those of external and those of internal freedom; the latter of which alone are ethical. Hence this internal freedom which is the condition of all ethical duty must be discussed as a preliminary (discursus praeliminaris), just as above the doctrine of conscience was discussed as the condition of all duty.

Of the Doctrine of Virtue on the Principle Of Internal Freedom.
Habit (habitus) is a facility of action and a subjective perfection of the elective will. But not every such facility is a free habit (habitus libertatis); for if it is custom (assuetudo), that is, a uniformity of action which, by frequent repetition, has become a necessity, then it is not a habit proceeding from freedom, and therefore not a moral habit. Virtue therefore cannot be defined as a habit of free law-abiding actions, unless indeed we add "determining itself in its action by the idea o

Emotions and passions are essentially distinct; the former belong to feeling in so far as this coming before reflection makes it more difficult or even impossible. Hence emotion is called hasty (animus praeceps). And reason declares through the notion of virtue that a man should collect himself; but this weakness in the life of one's understanding, joined with the strength of a mental excitement, is only a lack of virtue (Untugend), and as it were a weak and childish thing, which may very well c

XVII. Virtue necessarily presupposes Apathy (considered as Strength)
This word (apathy) has come into bad repute, just as if it meant want of feeling, and therefore subjective indifference with respect to the objects of the elective will; it is supposed to be a weakness. This misconception may be avoided by giving the name moral apathy to that want of emotion which is to be distinguished from indifference. In the former, the feelings arising from sensible impressions lose their influence on the moral feeling only because the respect for the law is more powerful t

The former follows from the fact that, objectively considered, it is an ideal and unattainable, and yet it is a duty constantly to approximate to it. The second is founded subjectively on the nature of man which is affected by inclinations, under the influence of which virtue, with its maxims adopted once for all, can never settle in a position of rest; but, if it is not rising, inevitably falls;
