Abstract
In the Philebus Socrates presents his division of the kinds of pleasures and pains to an interlocutor who confesses himself incapable of employing the dialectical method of division that this task ideally requires and is committed to defending a hedonist theory of value. These two features of his interlocutor affect the way in which Socrates presents his accounts of pleasure and pain. The philosophical reader needs to rethink the accounts of pleasure and pain to produce an account that is free from these limitations. In this paper I sketch the outlines of such an account, based on material that Socrates provides throughout the dialogue. I argue that there are two fundamental, mutually irreducible types of pain and pleasure: those produced by the disruption and restoration of a natural harmony, and those involving the representation of oneself as in a good or bad state. I then produce an account of pleasure and pain as such, which applies to both of these types: pleasure and pain are the cognition of oneself as in a good or bad state.
