It is complete virtue, first of all, because it is the exhibition of complete virtue: it is also complete because he that has it is able to exhibit virtue in dealing with his neighbours, and not merely in his private affairs; for there are many who can be virtuous enough at home, but fail in dealing with their neighbours.
This is the reason why people commend the saying of Bias, “Office will show the man:” for he that is in office ipso facto stands in relation to others, 93 and has dealings with them.
This, too, is the reason why justice alone of all the virtues is thought to be another’s good, as implying this relation to others; for it is another’s interest that justice aims at—the interest, namely, of the ruler or of our fellow-citizens.
