Let others praise justice and censure injustice, magnifying the rewards and honours of the one and abusing the other; that is a manner of arguing which, coming from them, I am ready to tolerate, but from you who have spent your whole life in the consideration of this question, unless I hear the contrary from your own lips, I expect something better.

And therefore, I say, not only prove to us that justice is better than injustice, but show what they either of them do to the possessor of them, which makes the one to be a good and the other an evil, whether seen or unseen by gods and men.
I had always admired the genius of Glaucon and Adeimantus, but on hearing these words I was quite delighted, and said: Sons of an illustrious father, that was not a bad beginning of the Elegiac verses which the admirer of Glaucon made in honour of you after you had distinguished yourselves at the battle of Megara:-- 'Sons of Ariston,' he sang, 'divine offspring of an illustrious hero.' The epithet is very appropriate, for there is something truly divine in being able to argue as you have done for the superiority of injustice, and remaining unconvinced by your own arguments.

And I do believe that you are not convinced--this I infer from your general character, for had I judged only from your speeches I should have mistrusted you.

But now, the greater my confidence in you, the greater is my difficulty in knowing what to say.

For I am in a strait between two; on the one hand I feel that I am unequal to the task; and my inability is brought home to me by the fact that you were not satisfied with the answer which I made to Thrasymachus, proving, as I thought, the superiority which justice has over injustice.
