Plotinus is careful to make us understand that his morality has neither an ascetic nor a suicidal tendency. Pleasures are to be tolerated under the form of a necessary relief and relaxation; pains are to be removed, but if incurable, they are to be patiently borne; anger is, if possible, to be suppressed, and, at any rate, not allowed to exceed the limits of an involuntary movement; fear will not be felt except as a salutary warning. The bodily appetites will be restricted to natural wants, and will not be felt by the soul, except, perhaps, as a transient excitement of the imagination.[496] Whatever abstinences our philosopher may have practised on his own account, we find no trace of a tendency towards self-mortification in his writings, nothing that is not consistent with the healthiest traditions of Greek spiritualism as originally constituted by the great Athenian school. While not absolutely condemning suicide, Plotinus restricts the right of leaving this world within much narrower limits than were assigned to it by the Stoics. In violently separating herself from the body, the soul, he tells us, is acting under the influence of some evil passion, and he intimates that the mischievous effects of this passion will prolong themselves into the new life on which she is destined to enter.[497] Translated into more abstract language, his meaning probably is that the feelings which ordinarily prompt to suicide, are such as would not exist in a well-regulated mind. It is remarkable that Schopenhauer, whose views of life were, on other points, the very reverse of those held by Plotinus, should have used very much the same argument against self-destruction. According to his theory, the will to life, which it should be our principal business to conquer, asserts itself strongly in the wish to escape from suffering, and only delays the final moment of peaceful extinction by rushing from one phase of existence to another. And in order to prove the possibility of such a revival, Schopenhauer was obliged to graft on his philosophy a theory of metempsychosis, which, but for this necessity, would certainly never have found a place in it at all. In this, as in many other instances, an ethical doctrine is apparently deduced from a metaphysical doctrine which has, in reality, been manufactured for its support. All systems do but present under different formulas a common fund of social sentiment. A constantly growing body of public opinion teaches us that we do not belong to ourselves, but to those about us, and that, in ordinary circumstances, it is no less weak and selfish to run away from life than to run away from death.
