SOCRATES: Seeing then that there are these two evils, the doing injustice and the suffering injustice—and we affirm that to do injustice is a greater, and to suffer injustice a lesser evil—by what devices can a man succeed in obtaining the two advantages, the one of not doing and the other of not suffering injustice? must he have the power, or only the will to obtain them? I mean to ask whether a man will escape injustice if he has only the will to escape, or must he have provided himself with the power?
CALLICLES: He must have provided himself with the power; that is clear.
SOCRATES: And what do you say of doing injustice? Is the will only sufficient, and will that prevent him from doing injustice, or must he have provided himself with power and art; and if he have not studied and practised, will he be unjust still? Surely you might say, Callicles, whether you think that Polus and I were right in admitting the conclusion that no one does wrong voluntarily, but that all do wrong against their will?
CALLICLES: Granted, Socrates, if you will only have done.
SOCRATES: Then, as would appear, power and art have to be provided in order that we may do no injustice?
CALLICLES: Certainly.
SOCRATES: And what art will protect us from suffering injustice, if not wholly, yet as far as possible? I want to know whether you agree with me; for I think that such an art is the art of one who is either a ruler or even tyrant himself, or the equal and companion of the ruling power.
CALLICLES: Well said, Socrates; and please to observe how ready I am to praise you when you talk sense.
SOCRATES: Think and tell me whether you would approve of another view of mine: To me every man appears to be most the friend of him who is most like to him—like to like, as ancient sages say: Would you not agree to this?
CALLICLES: I should.
