those incomparably greater mental sufferings, which, reaching forwards and backwards, draw upon the future and the past; and nature, by way of compensation, has granted to man alone the privilege of being able to end his life at his own pleasure, before she herself sets a term to it; thus, while animals necessarily live so long as they can, man need only live so long as he will.
Whether he ought on ethical grounds to forego this privilege is a difficult question, which in any case cannot be decided by the usual superficial reasoning. The arguments against suicide which Kant does not deem unworthy of adducing (p. 53, R., p. 48 and p. 67, R., p. 57), I cannot conscientiously describe as other than pitiable, and quite undeserving of an answer. It is laughable indeed to suppose that reflections of such a kind could have wrested the dagger from the hands of Cato, of Cleopatra, of Cocceius Nerva (Tac. Ann., vi. 26) or of Arria the wife of Paetus (Plin., Ep., iii. 16). If real moral motives for not committing suicide actually exist, it is certain that they lie very deep, and cannot be reached by the plummet of ordinary Ethics. They belong to a higher view of things than is adaptable even to the standpoint of the present treatise.[1]
That which generally comes next on the rubric of duties towards ourselves may be divided partly into rules of worldly wisdom, partly into hygienic prescriptions; but neither class belongs to Morals in the proper sense. Last on the catalogue comes the prohibition of unnatural lust—onanism, paederastia, and bestiality. Of these onanism is mainly a vice of childhood, and must be fought against much more with the weapon of dietetics than with that of ethics; hence we find that the authors of books directed against it are physicians (e.g., Tissot and others) rather than moralists. After dietetics and hygiene have done their work, and struck it down by irrefutable reasoning, if Ethics desires to take up the matter, she finds little left for her to do. Bestiality, again, is of very rare occurrence; it is thoroughly abnormal and exceptional, and, moreover, so loathsome and foreign to human nature, that itself, better than all arguments of reason, passes judgment on itself, and deters by sheer disgust. For the rest, as being a degradation of human nature, it is in reality an offence against the species as such, and in the abstract; not against human units. Of the three sexual perversions of which we are speaking it is consequently only with paederastia that Ethics has to do, and in treating of Justice this vice finds its proper place. For Justice is infringed by it, in face of which fact, the dictum volenti non fit injuria is unavailing. The injustice consists in the seduction of the younger and inexperienced person, who is thereby ruined physically and morally.

CHAPTER IV.
ON THE BASIS OF THE KANTIAN ETHICS.
With the imperative Form of Ethics, which in Chapter II. we proved to be a petitio principii, is directly connected a favourite idea of Kant's, that may be excused, but cannot be adopted. Sometimes we see a physician, after having employed a certain remedy with conspicuous success, henceforth prescribing it for almost all diseases; to such a one Kant may be likened. By separating the a priori from the a posteriori in human knowledge he made the most brilliant and pregnant discovery that Metaphysics can boast of. What wonder then that thereafter he should try to apply this method, this sundering of the two forms, everywhere, and should consequently make Ethics also consist of two parts, a pure, i.e. an a priori knowable part, and an empirical? The latter of these he rejects as unreliable for the purpose of founding Ethics. To trace out the former and; exhibit it by itself is his purpose in the Grundlegung der Metaphysik der Sitten, which he accordingly represents as a science purely a priori, exactly in the same way as he sets forth the Metaphysische Anfangsgründe der Naturwissenschaft. He asserts in fact that the Moral Law, which without warrant, without deduction, or proof of any sort, he postulates as existing, is furthermore a Law knowable a priori and independent of all internal or external experience; it "rests" (he says) "solely on conceptions of pure Reason; and is to be taken as a synthetic proposition a priori" (Kritik der Praktischen Vernunft: p. 56 of fourth Edition; R., p. 142). But from this definition the implication immediately follows that such a Law can only be formal, like everything else known a priori, and consequently has only to do with the Form of actions, not with their Essence. Let it be thought what this means! He emphatically adds (p. vi of the preface to the Grundlegung; R., p. 5) that it is "useless to look for it either subjectively in man's nature, or objectively in the accidents of the external world," and (preface of the same, page vii; R., p. 6) that "nothing whatever connected with it can be borrowed from knowledge relating to man, i.e., from anthropology." On page 59 (R., p. 52) he repeats, "That one ought on no account to fall into the mistake of trying to derive one's principle of morality from the special constitution of human nature"; and again, on page 60 (R., p. 52), he says that, "Everything derived from any natural disposition peculiar to man, or from certain feelings and propensities, or indeed from any special trend attaching solely to human nature, and not necessarily to be taken as the Will of every rational being," is incapable of affording a foundation for the moral law. This shows beyond all possibility of contradiction that Kant does not represent the alleged moral law as a fact of consciousness, capable of empirical proof—which is how the later would-be philosophers, both individually and collectively, wish to pass it off. In discarding every empirical basis for Morals, he rejects all internal, and still more decidedly all external, experience., Accordingly he founds—and I call special attention to this—his moral principle not on any provable fact of consciousness, such as an inner natural disposition, nor yet upon any objective relation of things in the external world. No! That would be an empirical foundation. Instead of this, pure conceptions a priori, i.e., conceptions, which so far contain nothing derived from internal or external experience, and thus are simply shells without kernels—these are to be made the basis of Morals. Let us consider the full meaning of such a position. Human consciousness as well as the whole external world, together with all the experience and all the facts they comprise, are swept from under our feet. We have nothing to stand upon. And what have we to hold to? Nothing but a few entirely abstract, entirely unsubstantial conceptions, floating in the air equally with ourselves. It is from these, or, more correctly, from the mere form of their connection with judgments made, that a Law is declared to proceed, which by so-called absolute necessity is supposed to be valid, and to be strong enough to lay bit and bridle on the surging throng of human desires, on the storm of passion, on the giant might of egoism. We shall see if such be the case.
With this preconceived notion that the basis of Morals must be necessarily and strictly a priori, and entirely free from everything empirical, another of Kant's favourite ideas is closely connected. The moral principle that he seeks to establish is, he says, a synthetic proposition a priori, of merely formal contents, and hence exclusively a matter of Pure Reason; and accordingly, as such, to be regarded as valid not only for men, but for all possible rational beings; indeed he declares it to hold good for man "on this account alone," i.e., because per accidens man comes under the category of rational beings. Here lies the cause of his basing the Moral principle not on any feeling, but on pure Reason (which knows nothing but itself and the statement of its antithesis). So that this pure Reason is taken, not as it really and exclusively is—an intellectual faculty of man—but as a self-existent hypostatic essence, yet without the smallest authority; the pernicious effects of such example and precedent being sufficiently shown in the pitiful philosophy of the present day. Indeed, this view of Morals as existing not for men, as men, but for all rational beings, as such, is with Kant a principle so firmly established, an idea so favourite, that he is never tired of repeating it at every opportunity.
