For mankind censure injustice, fearing that they may be the victims of it and not because they shrink from committing it.

And thus, as I have shown, Socrates, injustice, when on a sufficient scale, has more strength and freedom and mastery than justice; and, as I said at first, justice is the interest of the stronger, whereas injustice is a man's own profit and interest.
Thrasymachus, when he had thus spoken, having, like a bathman, deluged our ears with his words, had a mind to go away.

But the company would not let him; they insisted that he should remain and defend his position; and I myself added my own humble request that he would not leave us.

Thrasymachus, I said to him, excellent man, how suggestive are your remarks! And are you going to run away before you have fairly taught or learned whether they are true or not?
Is the attempt to determine the way of man's life so small a matter in your eyes--to determine how life may be passed by each one of us to the greatest advantage?
And do I differ from you, he said, as to the importance of the enquiry?
You appear rather, I replied, to have no care or thought about us, Thrasymachus--whether we live better or worse from not knowing what you say you know, is to you a matter of indifference.

Prithee, friend, do not keep your knowledge to yourself; we are a large party; and any benefit which you confer upon us will be amply rewarded.
