The Republic

Book I (continued)

Surely, he said, a man may be expected to love those whom he thinks good, and to hate those whom he thinks evil.

Yes, but do not persons often err about good and evil: many who are not good seem to be so, and conversely?

That is true.

Then to them the good will be enemies and the evil will be their friends? True.

And in that case they will be right in doing good to the evil and evil to the good?

Clearly.

But the good are just and would not do an injustice?

True.

Then according to your argument it is just to injure those who do no wrong?

Nay, Socrates; the doctrine is immoral.

Then I suppose that we ought to do good to the just and harm to the unjust?

I like that better.

But see the consequence:—Many a man who is ignorant of human nature has friends who are bad friends, and in that case he ought to do harm to them; and he has good enemies whom he ought to benefit; but, if so, we shall be saying the very opposite of that which we affirmed to be the meaning of Simonides.

Very true, he said: and I think that we had better correct an error into which we seem to have fallen in the use of the words ‘friend’ and ‘enemy.’

What was the error, Polemarchus? I asked.

We assumed that he is a friend who seems to be or who is thought good.

And how is the error to be corrected?

We should rather say that he is a friend who is, as well as seems, good; and that he who seems only, and is not good, only seems to be and is not a friend; and of an enemy the same may be said.

You would argue that the good are our friends and the bad our enemies?

Yes.

And instead of saying simply as we did at first, that it is just to do good to our friends and harm to our enemies, we should further say: It is just to do good to our friends when they are good and harm to our enemies when they are evil?

Yes, that appears to me to be the truth.

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 generally, 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 just 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.
