But these are bodily processes. If, then, pleasure be the replenishment of the normal state, that in which the replenishment takes place, i.e. the body, must be that which is pleased. But this does not seem to be the case. Pleasure, therefore, is not a replenishment, but while the process of replenishment is going on we may be pleased, and while the process of exhaustion is going on we may be pained. 246

This view of pleasure seems to have been suggested by the pleasures and pains connected with nutrition; for there it is true that we come into a state of want, and, after previous pain, find pleasure in replenishment. But this is not the case with all pleasures; for there is no previous pain involved in the pleasures of the mathematician, nor among the sensuous pleasures in those of smell, nor, again, in many kinds of sights and sounds, nor in memories and hopes. What is there, then, of which these pleasures are the becoming? Here there is nothing lacking that can be replenished.
