'Well, even you must know that cities are governed either as tyrannies, democracies, or aristocracies. Of course, I said. And that the government in each has the power... Well, each government frames laws for its own advantage, a democracy for democrats, a tyranny for tyrants, and so on. In so legislating, the rulers represent this - their own advantage - as justice for their subjects, and anyone who breaks their laws is punished as a lawbreaker and a criminal. Therefore I contend that justice is the same thing in every state: the advantage of the established ruling class. And since that presumably is the stronger class, anyone with a brain can calculate that justice is the same thing everywhere - the advantage of the stronger.' (The Republic, Book 1)
