Plato: The Republic

1. BOOK I (continued)

That I learn of others, I replied, is quite true; but that I am ungrateful I wholly deny. Money I have none, and therefore I pay in praise, which is all I have: and how ready I am to praise any one who appears to me to speak well you will very soon find out when you answer; for I expect that you will answer well.

Listen, then, he said; I proclaim that justice is nothing else than the interest of the stronger. And now why do you not me? But of course you won't.

Let me first understand you, I replied. justice, as you say, is the interest of the stronger. What, Thrasymachus, is the meaning of this? You cannot mean to say that because Polydamas, the pancratiast, is stronger than we are, and finds the eating of beef conducive to his bodily strength, that to eat beef is therefore equally for our good who are weaker than he is, and right and just for us?

That's abominable of you, Socrates; you take the words in the sense which is most damaging to the argument.

Not at all, my good sir, I said; I am trying to understand them; and I wish that you would be a little clearer.

Well, he said, have you never heard that forms of government differ; there are tyrannies, and there are democracies, and there are aristocracies?

Yes, I know.

And the government is the ruling power in each state?

Certainly.

And the different forms of government make laws democratical, aristocratical, tyrannical, with a view to their several interests; and these laws, which are made by them for their own interests, are the justice which they deliver to their subjects, and him who transgresses them they punish as a breaker of the law, and unjust. And that is what I mean when I say that in all states there is the same principle of justice, which is the interest of the government; and as the government must be supposed to have power, the only reasonable conclusion is, that everywhere there is one principle of justice, which is the interest of the stronger.
