Epicurus, like Aristotle and the other philosophers of his day, placed the highest good in happiness, or a happy life. More closely he makes pleasure to be the principal constituent of happiness, and even calls it the highest good. But Epicurus goes on to give a more accurate determination of pleasure, and in this he differs essentially from his predecessors, the Cyrenians. (_cf._ § XIII. 3.) 1. While with Aristippus the pleasure of the moment is made the end of human efforts, Epicurus directs men to strive after a system of pleasures which should insure an abiding course of happiness for the whole life. _True_ pleasure is thus the object to be considered and weighed. Many a pleasure should be despised because it will result in pain, and many a pain should be rejoiced in because it would lead to a greater pleasure. 2. Since the sage will seek after the highest good, not simply for the present but for his whole life, he will hold the pleasures and pains of the soul, which like memory and hope stretch over the past and the future, in greater esteem than those of the body, which relate only to the present moment. The pleasure of the soul consists in the untroubled tranquillity of the sage, who rests secure in the feeling of his inner worth and his exaltation above the strokes of destiny. Thus Epicurus, would say that it is better to be miserable but rational than to be happy and irrational, and that the wise man might be happy though in torture. He would even affirm, like a true follower of Aristotle, that pleasure and happiness were most closely connected with virtue, that virtue is in fact inseparable from true pleasure, and that there can be no agreeable life without virtue, and no virtue without an agreeable life.
