id: 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
