PLATO

THEAET. It seems so to me.
SOC. Is Theodorus a painter?
THEAET. Not as far as I know.
SOC. Is he perhaps a geometrician?
THEAET. In every way, I suspect, Socrates.
SOC. And an astronomer and an arithmetician and a musician and everything else that pertains to education?
THEAET. That is my opinion.
SOC. If then he says that we are similar in our bodies, whether praising or blaming in some way, it is not particularly worth paying attention to his opinion.
THEAET. Perhaps not.
B SOC. But what if he should praise the soul of either of us for virtue and wisdom? Would it not be worthy for the one who hears to be eager to examine the one who is praised, and for the one praised to eagerly exhibit himself?
THEAET. Certainly, Socrates.
SOC. It is time, therefore, my dear Theaetetus, for you to exhibit yourself, and for me to examine; for be well aware that Theodorus, although he has praised many foreigners and citizens to me, has never praised anyone as he has you just now.
THEAET. That would be well, Socrates; but see that he was not speaking in jest.
C SOC. That is not the way of Theodorus; but do not withdraw from what has been agreed upon by pretending that he is speaking in jest, lest he be forced to testify; for certainly no one will file a suit for perjury against him. Rather, take heart and stand by your agreement.
THEAET. Well, it must be done, if it seems right to you.
SOC. Tell me then: do you learn some things in geometry from Theodorus?
THEAET. I do.
