Aristotle, Nicomachean Ethics
H. Rackham, Ed.

We may then set aside that Justice which is coextensive with virtue in general, being the practice of virtue in general towards someone else, and that Injustice which is the practice of vice in general towards someone else. It is also clear how we should define what is just and unjust in the corresponding senses. For the actions that spring from virtue in general are in the main identical with the actions that are according to law, since the law enjoins conduct displaying the various particular virtues and forbids conduct displaying the various particular vices. Also the regulations laid down for the education that fits a man for social life are the rules productive of virtue in general.
