The virtue of the good man is necessarily the same as the virtue of the citizen of the perfect state.
AristotleThe wise man knows of all things, as far as possible, although he has no knowledge of each of them in detail
AristotleAnd inasmuch as the great-souled man deserves most, he must be the best of men; for the better a man is the more he deserves, and he that is best deserves most. Therefore the truly great-souled man must be a good man. Indeed greatness in each of the virtues would seem to go with greatness of soul.
Aristotle
