He is not my father, I said.
But can a father be other than a father? or are you the same as a stone?
I certainly do not think that I am a stone, I said, though I am afraid that you may prove me to be one.
Are you not other than a stone?
I am.
And being other than a stone, you are not a stone; and being other than gold, you are not gold?
Very true.
And so Chaeredemus, he said, being other than a father, is not a father?
I suppose that he is not a father, I replied.
For if, said Euthydemus, taking up the argument, Chaeredemus is a father, then Sophroniscus, being other than a father, is not a father; and you, Socrates, are without a father.
Ctesippus, here taking up the argument, said: And is not your father in the same case, for he is other than my father?
Assuredly not, said Euthydemus.
Then he is the same?
He is the same.
I cannot say that I like the connection; but is he only my father, Euthydemus, or is he the father of all other men?
Of all other men, he replied. Do you suppose the same person to be a father and not a father?
Certainly, I did so imagine, said Ctesippus.
And do you suppose that gold is not gold, or that a man is not a man?
They are not 'in pari materia,' Euthydemus, said Ctesippus, and you had better take care, for it is monstrous to suppose that your father is the father of all.
But he is, he replied.
What, of men only, said Ctesippus, or of horses and of all other animals?
Of all, he said.
And your mother, too, is the mother of all?
Yes, our mother too.
Yes; and your mother has a progeny of sea-urchins then?
Yes; and yours, he said.
And gudgeons and puppies and pigs are your brothers?
And yours too.
And your papa is a dog?
And so is yours, he said.
If you will answer my questions, said Dionysodorus, I will soon extract the same admissions from you, Ctesippus. You say that you have a dog.
Yes, a villain of a one, said Ctesippus.
And he has puppies?
Yes, and they are very like himself.
And the dog is the father of them?
Yes, he said, I certainly saw him and the mother of the puppies come together.
And is he not yours?
To be sure he is.
Then he is a father, and he is yours; ergo, he is your father, and the puppies are your brothers.
Let me ask you one little question more, said Dionysodorus, quickly interposing, in order that Ctesippus might not get in his word: You beat this dog?
Ctesippus said, laughing, Indeed I do; and I only wish that I could beat you instead of him.
Then you beat your father, he said.
I should have far more reason to beat yours, said Ctesippus; what could he have been thinking of when he begat such wise sons? much good has this father of you and your brethren the puppies got out of this wisdom of yours.
But neither he nor you, Ctesippus, have any need of much good.
And have you no need, Euthydemus? he said.
Neither I nor any other man; for tell me now, Ctesippus, if you think it good or evil for a man who is sick to drink medicine when he wants it; or to go to war armed rather than unarmed.
Good, I say. And yet I know that I am going to be caught in one of your charming puzzles.
That, he replied, you will discover, if you answer; since you admit medicine to be good for a man to drink, when wanted, must it not be good for him to drink as much as possible; when he takes his medicine, a cartload of hellebore will not be too much for him?
Ctesippus said: Quite so, Euthydemus, that is to say, if he who drinks is as big as the statue of Delphi.
And seeing that in war to have arms is a good thing, he ought to have as many spears and shields as possible?
