This document discusses ancient literary critics Plato and Aristotle. It summarizes Plato's view that literature is merely an imitation of reality and lacks truth, leading him to banish poets from his Republic. It then discusses Aristotle's Poetics, noting he emphasized literary form over subject matter. Aristotle defined tragedy as imitating noble actions, featuring a tragic hero with a flaw. He saw tragedy and comedy as different types of imitation that provide catharsis. Both critics had significant influence on the development of literary theory.
