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?
