But ought the just to injure any one at all? Undoubtedly he ought to injure those who are both wicked and his enemies. When horses are injured, are they improved or deteriorated? The latter. Deteriorated, that is to say, in the good qualities of horses, not of dogs? Yes, of horses. And dogs are deteriorated in the good qualities of dogs, and not of horses? Of course. And will not men who are injured be deteriorated in that which is the proper virtue of man? Certainly. And that human virtue is justice? To be sure. Then men who are injured are of necessity made unjust? That is the result. But can the musician by his art make men unmusical? Certainly not. Or the horseman by his art make them bad horsemen? Impossible. And can the just by justice make men unjust, or speaking general can the good by virtue make them bad? Assuredly not. Any more than heat can produce cold? It cannot. Or drought moisture? Clearly not. Nor can the good harm any one? Impossible. And the just is the good? Certainly. Then to injure a friend or any one else is not the act of a just man, but of the opposite, who is the unjust? I think that what you say is quite true, Socrates. Then if a man says that justice consists in the repayment of debts, and that good is the debt which a man owes to his friends, and evil the debt which he owes to his enemies,--to say this is not wise; for it is not true, if, as has been clearly shown, the injuring of another can be in no case just. I agree with you, said Polemarchus. Then you and I are prepared to take up arms against any one who attributes such a saying to Simonides or Bias or Pittacus, or any other wise man or seer? I am quite ready to do battle at your side, he said. Shall I tell you whose I believe the saying to be? Whose? I believe that Periander or Perdiccas or Xerxes or Ismenias the Theban, or some other rich and mighty man, who had a great opinion of his own power, was the first to say that justice is 'doing good to your friends and harm to your enemies.' Most true, he said. Yes, I said; but if this definition of justice also breaks down, what other can be offered? Several times in the course of the discussion Thrasymachus had made an attempt to get the argument into his own hands, and had been put down by the rest of the company, who wanted to hear the end. But when Polemarchus and I had done speaking and there was a pause, he could no longer hold his peace; and, gathering himself up, he came at us like a wild beast, seeking to devour us. We were quite panic-stricken at the sight of him. SOCRATES - POLEMARCHUS - THRASYMACHUS
