This paper discusses Greek tragedy and Aristotle. Aristotle argues that the function of Greek tragedy is to evoke pity and fear in the audience, and to achieve a "catharsis" or purgation of emotion. In simpler words, its purpose is to illuminate moral truths for the public. Aristotle believed that tragedy was the imitation of reality, intended to purify by arousing "pity and terror" in its spectators. He based his analysis on a few plays by Sophocles, most notably "King Oedipus", when he said that the central character of a tragedy should be a noble person who is brought down because of some flaw in his or her own nature.
