Gorgias

[483] For the suffering of injustice is not the part of a man, but of a slave, who indeed had better die than live; since when he is wronged and trampled upon, he is unable to help himself, or any other about whom he cares. The reason, as I conceive, is that the makers of laws are the majority who are weak; and they make laws and distribute praises and censures with a view to themselves and to their own interests; and they terrify the stronger sort of men, and those who are able to get the better of them, in order that they may not get the better of them; and they say, that dishonesty is shameful and unjust; meaning, by the word injustice, the desire of a man to have more than his neighbours; for knowing their own inferiority, I suspect that they are too glad of equality. And therefore the endeavour to have more than the many, is conventionally said to be shameful and unjust, and is called injustice (compare Republic), whereas nature herself intimates that it is just for the better to have more than the worse, the more powerful than the weaker; and in many ways she shows, among men as well as among animals, and indeed among whole cities and races, that justice consists in the superior ruling over and having more than the inferior. For on what principle of justice did Xerxes invade Hellas, or his father the Scythians? (not to speak of numberless other examples).
