SOCRATES: Would you say of drink, or of replenishment with drink?
PROTARCHUS: I should say, of replenishment with drink.
SOCRATES: Then he who is empty desires, as would appear, the opposite of what he experiences; for he is empty and desires to be full?
PROTARCHUS: Clearly so.
SOCRATES: But how can a man who is empty for the first time, attain either by perception or memory to any apprehension of replenishment, of which he has no present or past experience?
PROTARCHUS: Impossible.
SOCRATES: And yet he who desires, surely desires something?
PROTARCHUS: Of course.
SOCRATES: He does not desire that which he experiences, for he experiences thirst, and thirst is emptiness; but he desires replenishment?
PROTARCHUS: True.
