'Whether the just or the unjust is the happier.' He begins by dividing
goods into three classes:--first, goods desirable in themselves; secondly,
goods desirable in themselves and for their results; thirdly, goods
desirable for their results only. He then asks Socrates in which of the
three classes he would place justice. In the second class, replies
Socrates, among goods desirable for themselves and also for their results.
'Then the world in general are of another mind, for they say that justice

which he rejects. Glaucon thinks that Thrasymachus was too ready to listen
to the voice of the charmer, and proposes to consider the nature of justice

of the nature and origin of justice; secondly, of the manner in which men
view justice as a necessity and not a good; and thirdly, he will prove the

evil is discovered by experience to be greater than the good, the
sufferers, who cannot also be doers, make a compact that they will have

impossibility of doing injustice. No one would observe such a compact if
he were not obliged. Let us suppose that the just and unjust have two

do evil if he can. And he who abstains will be regarded by the world as a
fool for his pains. Men may praise him in public out of fear for
themselves, but they will laugh at him in their hearts (Cp. Gorgias.)

'And now let us frame an ideal of the just and unjust. Imagine the unjust
