Plato: The Republic

True.

Then when the person who asks me is not in his right mind I am by no means to make the return?

Certainly not.

When Simonides said that the repayment of a debt was justice, he did not mean to include that case?

Certainly not; for he thinks that a friend ought always to do good to a friend and never evil.

You mean that the return of a deposit of gold which is to the injury of the receiver, if the two parties are friends, is not the repayment of a debt,--that is what you would imagine him to say?

And are enemies also to receive what we owe to them?

To be sure, he said, they are to receive what we owe them, and an enemy, as I take it, owes to an enemy that which is due or proper to him-- that is to say, evil.

Simonides, then, after the manner of poets, would seem to have spoken darkly of the nature of justice; for he really meant to say that justice is the giving to each man what is proper to him, and this he termed a debt.

And what due or proper thing is given by cookery, and to what?

Seasoning to food.

And what is that which justice gives, and to whom?
