SOCRATES: And therefore he acts justly?
POLUS: Justly.
SOCRATES: Then he who is punished and suffers retribution, suffers justly?
POLUS: That is evident.
SOCRATES: And that which is just has been admitted to be honourable?
POLUS: Certainly.
SOCRATES: Then the punisher does what is honourable, and the punished suffers what is honourable?
POLUS: True.
SOCRATES: And if what is honourable, then what is good, for the honourable is either pleasant or useful?
POLUS: Certainly.
