2. The next point is to determine what is pleasure and what pain. Both are positive, i. e. pleasure is not the gratification of a want, nor does the absence of pleasure equal pain. The absence of either is a mere negative inactive state, and both pleasure and pain are motions of the soul (ἐν κινήσει). Pain was defined to be a violent, pleasure a moderate motion,--the first being compared to the sea in a storm, the second to the sea under a light breeze, the intermediate state of no-pleasure and no-pain to a calm--a simile not quite apposite, since a calm is not the middle state between a storm and a gentle breeze. In this denial of pleasure as a state of rest, we find Aristippus again opposed to Epicurus.
