"Socrates discusses courage or manliness with Euthydemos. In this case too, it appears, just as in the cases of piety and justice, that virtue is knowledge: courage is knowledge of the terrible or dangerous things. There is however one crucial difference between courage and those two virtues: courage has no relation to law."
