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.
As a proper appendage to such a system, Aristippus sketched a Psychology of Pleasure and Pain, which was important as a beginning, and is believed to have brought the subject into prominence.

The soul comes under three conditions,--a gentle, smooth, equable motion, corresponding to Pleasure; a rough, violent motion, which is Pain; and a calm, quiescent state, indifference or Unconsciousness.
