Certainly.
And are suits decided on any other ground but that a man may neither take what is another’s, nor be deprived of what is his own?
Yes; that is their principle.
Which is a just principle?
Yes.
Then on this view also justice will be admitted to be the having and doing what is a man’s own, and belongs to him?
Very true.
Think, now, and say whether you agree with me or not. Suppose a carpenter to be doing the business of a cobbler, or a cobbler of a carpenter; and suppose them to exchange their implements or their duties, or the same person to be doing the work of both, or whatever be the change; do you think that any great harm would result to the State?
Not much.
But when the cobbler or any other man whom nature designed to be a trader, having his heart lifted up by wealth or strength or the number of his followers, or any like advantage, attempts to force his way into the class of warriors, or a warrior into that of legislators and guardians, for which he is unfitted, and either to take the implements or the duties of the other; or when one man is trader, legislator, and warrior all in one, then I think you will agree with me in saying that this interchange and this meddling of one with another is the ruin of the State.
Most true.
Seeing then, I said, that there are three distinct classes, any meddling of one with another, or the change of one into another, is the greatest harm to the State, and may be most justly termed evildoing?
Precisely.
And the greatest degree of evildoing to one’s own city would be termed by you injustice?
Certainly.
This then is injustice; and on the other hand when the trader, the auxiliary, and the guardian each do their own business, that is justice, and will make the city just.
I agree with you.
We will not, I said, be over-positive as yet; but if, on trial, this conception of justice be verified in the individual as well as in the State, there will be no longer any room for doubt; if it be not verified, we must have a fresh enquiry. First let us complete the old investigation, which we began, as you remember, under the impression that, if we could previously examine justice on the larger scale, there would be less difficulty in discerning her in the individual. That larger example appeared to be the State, and accordingly we constructed as good a one as we could, knowing well that in the good State justice would be found. Let the discovery which we made be now applied to the individual—if they agree, we shall be satisfied; or, if there be a difference in the individual, we will come back to the State and have another trial of the theory. The friction of the two when rubbed together may possibly strike a light in which justice will shine forth, and the vision which is then revealed we will fix in our souls.
That will be in regular course; let us do as you say.
I proceeded to ask: When two things, a greater and less, are called by the same name, are they like or unlike in so far as they are called the same?
Like, he replied.
The just man then, if we regard the idea of justice only, will be like the just State?
He will.
And a State was thought by us to be just when the three classes in the State severally did their own business; and also thought to be temperate and valiant and wise by reason of certain other affections and qualities of these same classes?
True, he said.
