Euthydemus

by Plato

Yes, I do.

Then do you see our garments?

Yes.

Then our garments have the quality of vision.

They can see to any extent, said Ctesippus.

What can they see?

Nothing; but you, my sweet man, may perhaps imagine that they do not see; and certainly, Euthydemus, you do seem to me to have been caught napping when you were not asleep, and that if it be possible to speak and say nothing—you are doing so.

And may there not be a silence of the speaker? said Dionysodorus.

Impossible, said Ctesippus.

Or a speaking of the silent?
