Aristippus did not write an account of his system; and the particulars of his life, which would show how he acted it, are but imperfectly preserved. He was the first theorist to avow and maintain that Pleasure, and the absence of Pain, are the proper, the direct, the immediate, the sole end of living; not of course mere present pleasures and present relief from pain, but present and future taken in one great total. He would surrender present pleasure, and incur present pain, with a view to greater future good; but he did not believe in the necessity of that extreme surrender and renunciation enjoined by the Cynics. He gratified all his appetites and cravings within the limits of safety. He could sail close upon the island of Calypso without surrendering himself to the sorceress. Instead of deadening the sexual appetite he gave it scope, and yet resisted the dangerous consequences of associating with Hetaerae. In his enjoyments he was free from jealousies; thinking it no derogation to his pleasure that others had the same pleasure. Having thus a fair share of natural indulgences, he dispenses with the Cynic pride of superiority and the luxury of contemning other men. Strength of will was required for this course no less than for the Cynic life. Aristippus put forward strongly the impossibility of realizing all the Happiness that might seem within one's reach; such were the attendant and deterring evils, that many pleasures had to be foregone by the wise man. Sometimes even the foolish person attained more pleasure than the wise; such is the lottery of life; but, as a general rule, the fact would be otherwise. The wisest could not escape the natural evils, pain and death; but envy, passionate love, and superstition, being the consequences of vain and mistaken opinion, might be conquered by a knowledge of the real nature of Good and Evil.
