further
consider is, whether this power which is possessed by the superior
state can exist or be exercised without justice.

If you are right in you view, and justice is wisdom, then only with
justice; but if I am right, then without justice.

I am delighted, Thrasymachus, to see you not only nodding assent and
dissent, but making answers which are quite excellent.

That is out of civility to you, he replied.

You are very kind, I said; and would you have the goodness also to
inform me, whether you think that a state, or an army, or a band of
robbers and thieves, or any other gang of evil-doers could act at all
if they injured one another?

No indeed, he said, they could not.

But if they abstained from injuring one another, then they might act
together better?

Yes.

And this is because injustice creates divisions and hatreds and
fighting, and justice imparts harmony and friendship; is not that true,
Thrasymachus?

I agree, he said, because I do not wish to quarrel with you.

How good of you, I said; but I should like to know also whether
injustice, having this tendency to arouse hatred, wherever existing,
among slaves or among freemen, will not make them hate one another and
set them at variance and render them incapable of common action?

Certainly.

And even if injustice be found in two only, will they not quarrel and
fight, and become enemies to one another and to the just.

They will.

And suppose injustice abiding in a single person, would your wisdom say
that she loses or that she retains her natural power?

Let us assume that she retains her power.

Yet is not the power which injustice exercises of such a nature that
wherever she takes up her abode, whether in a city, in an army, in a
family, or in any other body, that body is, to begin with, rendered
incapable of united action by reason of sedition and distraction; and
does it not become its own enemy and at variance with all that opposes
it, and with the just? Is not this the case?

Yes, certainly.

And is not injustice equally fatal when existing in a single person; in
the first place rendering him incapable of action because he is not at
unity with himself, and in the second place making him an enemy to
himself and the just? Is not that true, Thrasymachus?

Yes.

And O my friend, I said, surely the gods are just?

Granted that they are.

But if so, the unjust will be the enemy of the gods, and the just will
be their friend?
