This document discusses the concept of catharsis. It begins by noting there is controversy around the exact meaning of catharsis. It then examines Aristotle's view that tragedy accomplishes a purification of emotions through pity and fear. It also discusses alternative interpretations that catharsis means purgation, moderation of passions, or a release of emotions. The document questions how accurate Aristotle's view of catharsis is and explores what led Aristotle to adopt this theory, noting it was partly a response to Plato's criticisms of poetry.
