This is the style in which they praise justice.

But about the wicked there is another strain; they bury them in a slough in Hades, and make them carry water in a sieve; also while they are yet living they bring them to infamy, and inflict upon them the punishments which Glaucon described as the portion of the just who are reputed to be unjust; nothing else does their invention supply.

Such is their manner of praising the one and censuring the other.
Once more, Socrates, I will ask you to consider another way of speaking about justice and injustice, which is not confined to the poets, but is found in prose writers.

The universal voice of mankind is always declaring that justice and virtue are honourable, but grievous and toilsome; and that the pleasures of vice and injustice are easy of attainment, and are only censured by law and opinion.

They say also that honesty is for the most part less profitable than dishonesty; and they are quite ready to call wicked men happy, and to honour them both in public and private when they are rich or in any other way influential, while they despise and overlook those who may be weak and poor, even though acknowledging them to be better than the others.
