The ethics of Democritus, in so far as we may judge from scanty evidence, were merely descriptive or satirical. He was an aristocratic observer, a scorner of fools. Nature was laughing at us all; the wise man considered his fate and, by knowing it, raised himself in a measure above it. All living things pursued the greatest happiness they could see their way to; but they were marvellously short-sighted; and the business of the philosopher was to foresee and pursue the greatest happiness that was really possible. This, in so rough a world, was to be found chiefly in abstention and retrenchment. If you asked for little, it was more probable that the event would not disappoint you. It was important not to be a fool, but it was very hard. The system of Democritus was adopted by Epicurus, but not because Epicurus had any keenness of scientific vision. On the contrary, Epicurus, the Herbert Spencer of antiquity, was in his natural philosophy an encyclopaedia of second-hand knowledge. Prolix and minute, vague and inconsistent, he gathered his scientific miscellany with an eye fixed not on nature, but on the exigencies of an inward faith,--a faith accepted on moral grounds, deemed necessary to salvation, and defended at all costs, with any available weapon. It is instructive that materialism should have been adopted at that juncture on the same irrelevant moral grounds on which it has usually been rejected. Epicurus, strange as it may sound to those who have heard, with horror or envy, of wallowing in his sty, Epicurus was a saint. The ways of the world filled him with dismay. The Athens of his time, which some of us would give our eyes to see, retained all its splendour amid its political decay; but nothing there interested or pleased Epicurus. Theatres, porches, gymnasiums, and above all the agora, reeked, to his sense, with vanity and folly. Retired in his private garden, with a few friends and disciples, he sought the ways of peace; he lived abstemiously; he spoke gently; he gave alms to the poor; he preached against wealth, against ambition, against passion. He defended free-will because he wished to exercise it in withdrawing from the world, and in not swimming with the current. He denied the supernatural, since belief in it would have a disquieting influence on the mind, and render too many things compulsory and momentous. There was no future life: the art of living wisely must not be distorted by such wild imaginings.
