SOCRATES: Thereupon, Crito, seeing that I was on the point of shipwreck, I
lifted up my voice, and earnestly entreated and called upon the strangers
to save me and the youth from the whirlpool of the argument; they were our
Castor and Pollux, I said, and they should be serious, and show us in sober
earnest what that knowledge was which would enable us to pass the rest of
our lives in happiness.

CRITO: And did Euthydemus show you this knowledge?

SOCRATES: Yes, indeed; he proceeded in a lofty strain to the following
effect: Would you rather, Socrates, said he, that I should show you this
knowledge about which you have been doubting, or shall I prove that you
already have it?

What, I said, are you blessed with such a power as this?

Indeed I am.

Then I would much rather that you should prove me to have such a knowledge;
at my time of life that will be more agreeable than having to learn.

Then tell me, he said, do you know anything?

Yes, I said, I know many things, but not anything of much importance.

That will do, he said: And would you admit that anything is what it is,
and at the same time is not what it is?

Certainly not.
