[476e]
Socrates
And he who punishes aright punishes justly?
Polus
Yes.
Socrates
Doing what is just, or not?
Polus
What is just.
Socrates
And he who pays the penalty by being punished suffers what is just?
Polus
Apparently.
Socrates
And what is just, I think we have agreed, is fair?
Polus
Certainly.
Socrates
Then of these two, the one does what is fair and the other, he who is punished, suffers it.
Polus
Yes.
