THREE:It was not, however, in any of these concessions that the Stoics found from first to last their most efficient solution for the difficulties of practical experience, but in the countenance they extended to an act which, more than any other, might have seemed fatally inconsistent both in spirit and in letter with their whole system, whether we choose to call it a defiance of divine law, a reversal of natural instinct, a selfish abandonment of duty, or a cowardly shrinking from pain. We allude, of course, to their habitual recommendation of suicide. If you are not satisfied with life, they said,31 you have only got to rise and depart; the door is always open. Various circumstances were specified in which the sage would exercise the privilege of taking himself off, as they euphemistically expressed it. Severe pain, mutilation, incurable disease, advanced old age, the hopelessness of escaping from tyranny, and in general any hindrance to leading a natural life, were held to be a sufficient justification for such a step.71 The first founders of the school set an example afterwards frequently followed. Zeno is said to have hanged himself for no better reason than that he fell and broke his finger through the weakness of old age; and Cleanthes, having been ordered to abstain temporarily from food, resolved, as he expressed it, not to turn back after going half-way to death.72 This side of the Stoic doctrine found particular favour in Rome, and the voluntary death of Cato was always spoken of as his chief title to fame. Many noble spirits were sustained in their defiance of the imperial despotism by the thought that there was one last liberty of which not even Caesar could deprive them. Objections were silenced by the argument that, life not being an absolute good, its loss might fairly be preferred to some relatively greater inconvenience.73 But why the sage should renounce an existence where perfect happiness depends entirely on his own will, neither was, nor could it be, explained.Plato knew perfectly well that although rhetoricians and men of the world might be silenced, they could not be converted nor even convinced by such arguments as these. So far from thinking it possible to reason men into virtue, he has observed of those who are slaves to their senses that you must improve them before you can teach them the truth.L And he234 felt that if the complete assimilation of the individual and the community was to become more than a mere logical formula, it must be effected by a radical reform in the training of the one and in the institutions of the other. Accordingly, he set himself to elaborate a scheme for the purpose, our knowledge of which is chiefly derived from his greatest work, the Republic. We have already made large use of the negative criticism scattered through that Dialogue; we have now to examine the positive teaching by which it was supplemented.
