Euthydemus

by Plato

But when the teacher dictates to you, does he not dictate letters?

To this also he assented.

Then if you know all letters, he dictates that which you know?

This again was admitted by him.

Then, said the other, you do not learn that which he dictates; but he only who does not know letters learns?

Nay, said Cleinias; but I do learn.

Then, said he, you learn what you know, if you know all the letters?

He admitted that.

Then, he said, you were wrong in your answer.

The word was hardly out of his mouth when Dionysodorus took up the argument, like a ball which he caught, and had another throw at the youth. Cleinias, he said, Euthydemus is deceiving you. For tell me now, is not learning acquiring knowledge of that which one learns?
