The Nicomachean ethics of Aristotle · Aristotle
Chapter II.
However, Justice in this sense is not a part of Virtue but is co-extensive with Virtue; nor is the Injustice which answers to it a part of Vice but co-extensive with Vice. Now wherein Justice in this sense differs from Virtue appears from what has been said: it is the same really, but the point of view is not the same: in so far as it has respect to one’s neighbour it is Justice, in so far as it is such and such a moral state it is simply Virtue.
