Yes, he would.
And what of the unjust – does he claim to have more than the just man and to do more than is just?
Of course, he said, for he claims to have more than all men.
And the unjust man will strive and struggle to obtain more than the unjust man or action, in order that he may have more than all?
True.
We may put the matter thus, I said – the just does not desire more than his like but more than his unlike, whereas the unjust desires more than both his like and his unlike?
Nothing, he said, can be better than that statement.
And the unjust is good and wise, and the just is neither?
Good again, he said.
And is not the unjust like the wise and good and the just unlike them?
Of course, he said, he who is of a certain nature, is like those who are of a certain nature; he who is not, not.
Each of them, I said, is such as his like is?
Certainly, he replied.
Very good, Thrasymachus, I said; and now to take the case of the arts: you would admit that one man is a musician and another not a musician?
Yes.
And which is wise and which is foolish?
Clearly the musician is wise, and he who is not a musician is foolish.
And he is good in as far as he is wise, and bad in as far as he is foolish?
Yes.
And you would say the same sort of thing of the physician?
Yes.
And do you think, my excellent friend, that a musician when he adjusts the lyre would desire or claim to exceed or go beyond a musician in the tightening and loosening the strings?
I do not think that he would.
But he would claim to exceed the non-musician?
Of course.
And what would you say of the physician? In prescribing meats and drinks would he wish to go beyond another physician or beyond the practice of medicine?
He would not.
But he would wish to go beyond the non-physician?
Yes.
And about knowledge and ignorance in general; see whether you think that any man who has knowledge ever would wish to have the choice of saying or doing more than another man who has knowledge. Would he not rather say or do the same as his like in the same case?
That, I suppose, can hardly be denied.
And what of the ignorant? would he not desire to have more than either the knowing or the ignorant?
I dare say.
And the knowing is wise?
Yes.
And the wise is good?
True.
Then the wise and good will not desire to gain more than his like, but more than his unlike and opposite?
I suppose so.
Whereas the bad and ignorant will desire to gain more than both?
Yes.
But did we not say, Thrasymachus, that the unjust goes beyond both his like and unlike? Were not these your words?
They were.
And you also said that the just will not go beyond his like but his unlike?
Yes.
Then the just is like the wise and good, and the unjust like the evil and ignorant?
That is the inference.
And each of them is such as his like is?
That was admitted.
Then the just has turned out to be wise and good and the unjust evil and ignorant.
