Had this been the universal strain, had you sought to persuade us of this from our youth upwards, we should not have been on the watch to keep one another from doing wrong, but every one would have been his own watchman, because afraid, if he did wrong, of harbouring in himself the greatest of evils.

I dare say that Thrasymachus and others would seriously hold the language which I have been merely repeating, and words even stronger than these about justice and injustice, grossly, as I conceive, perverting their true nature.

But I speak in this vehement manner, as I must frankly confess to you, because I want to hear from you the opposite side; and I would ask you to show not only the superiority which justice has over injustice, but what effect they have on the possessor of them which makes the one to be a good and the other an evil to him.

And please, as Glaucon requested of you, to exclude reputations; for unless you take away from each of them his true reputation and add on the false, we shall say that you do not praise justice, but the appearance of it; we shall think that you are only exhorting us to keep injustice dark, and that you really agree with Thrasymachus in thinking that justice is another's good and the interest of the stronger, and that injustice is a man's own profit and interest, though injurious to the weaker.

Now as you have admitted that justice is one of that highest class of goods which are desired indeed for their results, but in a far greater degree for their own sakes--like sight or hearing or knowledge or health, or any other real and natural and not merely conventional good--I would ask you in your praise of justice to regard one point only: I mean the essential good and evil which justice and injustice work in the possessors of them.
