Socrates: Whether the many agree or not, and whether we must additionally suffer harsher things than these or gentler, nevertheless acting unjustly is evil and shameful in every way for the person who does it. Do we say this or not?
Crito: We do.
So: And so one must never act unjustly.
Cr: By no means.
So: And so one should not repay an injustice with an injustice, as the many think, since one should never act unjustly.
Cr: It appears not.
So: What next? Should one cause harm, Crito, or not?
Cr: Presumably not, Socrates.
So: And then? Is returning a harm for a harm just, as the many say, or not just?
Cr: Not at all.
So: Because harming a man in any way is no different from doing an injustice.
Cr: That’s true.
So: One must neither repay an injustice nor cause harm to any man, no matter what one suffers because of him. And see to it, Crito, that in agreeing with this you are not agreeing contrary to what you believe, because I know that few people believe it and would continue to believe it. And there is no common ground between those who hold this and those who don’t, but when they see each other’s positions they are bound to despise one other. So think carefully about whether you yourself agree and believe it and let us begin thinking from here, that it is never right to act unjustly or to return an injustice or to retaliate when one has suffered some harm by repaying the harm. Do you reject or accept this starting principle?
