Aristotle

“Tragedy, then, is an imitation of an action that is serious, complete, and of a certain magnitude...through pity and fear effecting the proper purgation of these emotions.”

“Logic... not a single division, turning on one special point, but being rather an instrument for every art brought to a high degree of accuracy.”

“A city is a natural production, and man is naturally a political animal, and whosoever is naturally and not accidentally unfit for society, must be either inferior or superior to man.”

“It is a working of the soul in the way of excellence or virtue of a certain kind.”

“The good man is to his friend as to himself, friend being but a name for a second Self.”

“Virtue then is in a sense a mean state, since it certainly has an aptitude for aiming at the mean.”
