SOCRATES: Then, now let us proceed to contemplate this difference.
PROTARCHUS: Lead, and I will follow.
SOCRATES: Well, then, my view is—
PROTARCHUS: What is it?
SOCRATES: We agree—do we not?—that there is such a thing as false, and also such a thing as true opinion?
PROTARCHUS: Yes.
SOCRATES: And pleasure and pain, as I was just now saying, are often consequent upon these—upon true and false opinion, I mean.
PROTARCHUS: Very true.
SOCRATES: And do not opinion and the endeavour to form an opinion always spring from memory and perception?
PROTARCHUS: Certainly.
