Euthydemus

Certainly, of the knowledge which I have.

That makes no difference; – and must you not, if you are knowing, know all things?

Certainly not, I said, for there are many other things which I do not know.

And if you do not know, you are not knowing.

Yes, friend, of that which I do not know.

Still you are not knowing, and you said just now that you were knowing; and therefore you are and are not at the same time, and in reference to the same things.

A pretty clatter, as men say, Euthydemus, this of yours! and will you explain how I possess that knowledge for which we were seeking? Do you mean to say that the same thing cannot be and also not be; and therefore, since I know one thing, that I know all, for I cannot be knowing and not knowing at the same time, and if I know all things, then I must have the knowledge for which we are seeking – May I assume this to be your ingenious notion?

Out of your own mouth, Socrates, you are convicted, he said.

Well, but, Euthydemus, I said, has that never happened to you? for if I am only in the same case with you and our beloved Dionysodorus, I cannot complain. Tell me, then, you two, do you not know some things, and not know others?

Certainly not, Socrates, said Dionysodorus.

What do you mean, I said; do you know nothing?

Nay, he replied, we do know something.

Then, I said, you know all things, if you know anything?

Yes, all things, he said; and that is as true of you as of us.

O, indeed, I said, what a wonderful thing, and what a great blessing! And do all other men know all things or nothing?

Certainly, he replied; they cannot know some things, and not know others, and be at the same time knowing and not knowing.

Then what is the inference? I said.

They all know all things, he replied, if they know one thing.

O heavens, Dionysodorus, I said, I see now that you are in earnest; hardly have I got you to that point. And do you really and truly know all things, including carpentering and leather-cutting?

Certainly, he said.

And do you know stitching?

Yes, by the gods, we do, and cobbling, too.

And do you know things such as the numbers of the stars and of the sand?

Certainly; did you think we should say No to that?

By Zeus, said Ctesippus, interrupting, I only wish that you would give me some proof which would enable me to know whether you speak truly.

What proof shall I give you? he said.

Will you tell me how many teeth Euthydemus has? and Euthydemus shall tell how many teeth you have.

Will you not take our word that we know all things?

Certainly not, said Ctesippus: you must further tell us this one thing, and then we shall know that you are speak the truth; if you tell us the number, and we count them, and you are found to be right, we will believe the rest. They fancied that Ctesippus was making game of them, and they refused, and they would only say in answer to each of his questions, that they knew all things. For at last Ctesippus began to throw off all restraint; no question in fact was too bad for him; he would ask them if they knew the foulest things, and they, like wild boars, came rushing on his blows, and fearlessly replied that they did. At last, Crito, I too was carried away by my incredulity, and asked Euthydemus whether Dionysodorus could dance.

Certainly, he replied.

And can he vault among swords, and turn upon a wheel, at his age? has he got to such a height of skill as that?

He can do anything, he said.

And did you always know this?

Always, he said.

When you were children, and at your birth?

They both said that they did.

This we could not believe. And Euthydemus said: You are incredulous, Socrates.

Yes, I said, and I might well be incredulous, if I did not know you to be wise men.

But if you will answer, he said, I will make you confess to similar marvels.

Well, I said, there is nothing that I should like better than to be self-convicted of this, for if I am really a wise man, which I never knew before, and you will prove to me that I know and have always known all things, nothing in life would be a greater gain to me.

Answer then, he said.

Ask, I said, and I will answer.

Do you know something, Socrates, or nothing?

Something, I said.

And do you know with what you know, or with something else?

With what I know; and I suppose that you mean with my soul?

Are you not ashamed, Socrates, of asking a question when you are asked one?

Well, I said; but then what am I to do? for I will do whatever you bid; when I do not know what you are asking, you tell me to answer nevertheless, and not to ask again.

Why, you surely have some notion of my meaning, he said.

Yes, I replied.
