Full Idea
Aristotle notoriously has difficulty in finding the specific emotion that is displayed in just and unjust actions, and equal difficulty in distinguishing the two errors of deficiency and excess required by the doctrine of the mean.
Gist of Idea
What emotion is displayed in justice, and what are its deficiency and excess?

A Reaction
Not a criticism of Aristotle, but it opens up the complexity of his view. It seems to make justice a super-virtue, a combination of lesser sets of combined mean and right feeling. Maybe.
