Or is not what we used to say most certainly true, whether the world agree or not? And whether we must endure still more grievous sufferings than these, or lighter ones, is not wrongdoing inevitably an evil and a disgrace to the wrongdoer? Do we believe this or not? Crito. We do. Socrates. Then we ought not to do wrong at all. Crito. Why, no. Socrates. And we ought not even to requite wrong with wrong, as the world thinks, since we must not do wrong at all. Crito. Apparently not. Socrates. Well, Crito, ought one to do evil or not? Crito. Certainly not, Socrates. Socrates. Well, then, is it right to requite evil with evil, as the world says it is, or not right? Crito. Not right, certainly. Socrates. For doing evil to people is the same thing as wronging them. Crito. That is true. Socrates.
The quote: Then we ought neither to requite wrong with wrong nor to do evil to anyone, no matter what he may have done to us.
And be careful, Crito, that you do not, in agreeing to this, agree to something you do not believe; for I know that there are few who believe or ever will believe this. Now those who believe this, and those who do not, have no common ground of discussion, but they must necessarily, in view of their opinions, despise one another.
