CRITO: Surely not, Socrates.

SOCRATES: And what of doing evil in return for evil, which is the morality
of the many--is that just or not?

CRITO: Not just.

SOCRATES: For doing evil to another is the same as injuring him?

CRITO: Very true.

SOCRATES: Then we ought not to retaliate or render evil for evil to any
one, whatever evil we may have suffered from him. But I would have you
consider, Crito, whether you really mean what you are saying. For this
opinion has never been held, and never will be held, by any considerable
number of persons; and those who are agreed and those who are not agreed
upon this point have no common ground, and can only despise one another
when they see how widely they differ. Tell me, then, whether you agree
with and assent to my first principle, that neither injury nor retaliation
nor warding off evil by evil is ever right. And shall that be the premiss
of our argument? Or do you decline and dissent from this? For so I have
ever thought, and continue to think; but, if you are of another opinion,
let me hear what you have to say. If, however, you remain of the same mind
as formerly, I will proceed to the next step.

CRITO: You may proceed, for I have not changed my mind.

SOCRATES: Then I will go on to the next point, which may be put in the
form of a question:--Ought a man to do what he admits to be right, or ought
he to betray the right?
