Then, I said, I do not know this.

You are ruining the argument, said Euthydemus to Dionysodorus; he will be proved not to know, and then after all he will be knowing and not knowing at the same time.

Dionysodorus blushed.

I turned to the other, and said, What do you think, Euthydemus? Does not your omniscient brother appear to you to have made a mistake?

What, replied Dionysodorus in a moment; am I the brother of Euthydemus?

Thereupon I said, Please not to interrupt, my good friend, or prevent Euthydemus from proving to me that I know the good to be unjust; such a lesson you might at least allow me to learn.

You are running away, Socrates, said Dionysodorus, and refusing to answer.

No wonder, I said, for I am not a match for one of you, and a fortiori I must run away from two. I am no Heracles; and even Heracles could not fight against the Hydra, who was a she-Sophist, and had the wit to shoot up many new heads when one of them was cut off; especially when he saw a second monster of a sea-crab, who was also a Sophist, and appeared to have newly arrived from a sea-voyage, bearing down upon him from the left, opening his mouth and biting. When the monster was growing troublesome he called Iolaus, his nephew, to his help, who ably succoured him; but if my Iolaus, who is my brother Patrocles (the statuary), were to come, he would only make a bad business worse.

And now that you have delivered yourself of this strain, said Dionysodorus, will you inform me whether Iolaus was the nephew of Heracles any more than he is yours?

I suppose that I had best answer you, Dionysodorus, I said, for you will insist on asking—that I pretty well know—out of envy, in order to prevent me from learning the wisdom of Euthydemus.
