The Story of Philosophy《哲学的故事》第1章Plato第4节IV. The Ethical Problem第3段第1句：
Socrates is not frightened; he continues to ask rather than answer; and after a minute of parry and thrust he provokes the unwary Thrasymachus to commit himself to a definition:
"Listen, then," says the angry Sophist, "I proclaim that might is right, and just is the interest of the stronger…. The different forms of government make laws, democratic, aristocratic, or autocratic, with a view to their respective interests; and these laws, so made by them to serve their interests, they deliver to their subjects a 'justice', and punish as 'unjust' anyone who transgresses them…. I am speaking of injustice on a large scale; and my meaning will be most clearly seen in autocracy, which by fraud and force takes away the property of others, not retail but wholesale. Now when a man has taken away the money of the citizens and made slaves of them, then, instead of swindler and thief he is called happy and blessed by all. For injustice is censured because those who censure it are afraid of suffering, and not from any scruple they might have of doing injustice themselves"(3338-44).
