SOCRATES: There is a reason why I say all this.
PROTARCHUS: What is it?
SOCRATES: I want to attain the plainest possible notion of pleasure and desire, as they exist in the mind only, apart from the body; and the previous analysis helps to show the nature of both.
PROTARCHUS: Then now, Socrates, let us proceed to the next point.
SOCRATES: There are certainly many things to be considered in discussing the generation and whole complexion of pleasure. At the outset we must determine the nature and seat of desire.
PROTARCHUS: Ay; let us enquire into that, for we shall lose nothing.
SOCRATES: Nay, Protarchus, we shall surely lose the puzzle if we find the answer.
PROTARCHUS: A fair retort; but let us proceed.
SOCRATES: Did we not place hunger, thirst, and the like, in the class of desires?
PROTARCHUS: Certainly.
