The aim of education is to make the pupil like and dislike what he ought....The little human animal will not at first have the right responses. It must be trained to feel pleasure, liking, disgust, and hatred at those things which really are pleasant, likable, disgusting, and hateful.
The angry man wishes the object of his anger to suffer in return; hatred wishes its object not to exist.
Aristotle said: "Evil brings men together."
