SOCRATES: Memory and perception meet, and they and their attendant feelings seem to almost to write down words in the soul, and when the inscribing feeling writes truly, then true opinion and true propositions which are the expressions of opinion come into our souls—but when the scribe within us writes falsely, the result is false.

PROTARCHUS: I quite assent and agree to your statement.

SOCRATES: I must bespeak your favour also for another artist, who is busy at the same time in the chambers of the soul.

PROTARCHUS: Who is he?

SOCRATES: The painter, who, after the scribe has done his work, draws images in the soul of the things which he has described.

PROTARCHUS: But when and how does he do this?

SOCRATES: When a man, besides receiving from sight or some other sense certain opinions or statements, sees in his mind the images of the subjects of them;—is not this a very common mental phenomenon?

PROTARCHUS: Certainly.

SOCRATES: And the images answering to true opinions and words are true, and to false opinions and words false; are they not?

PROTARCHUS: They are.
