Poetry demands a man with a special gift for it, or else one with a touch of madness in him.
AristotleThe soul is characterized by these capacities; self-nutrition, sensation, thinking, and movement.
AristotleSince the branch of philosophy on which we are at present engaged differs from the others in not being a subject of merely intellectual interest — I mean we are not concerned to know what goodness essentially is, but how we are to become good men, for this alone gives the study its practical value — we must apply our minds to the solution of the problems of conduct.
Aristotle
