Meaning "purgation," catharsis describes the release of the emotions of pity and fear by the audience at the end of a tragedy. In his Poetics, Aristotle discusses the importance of catharsis. The audience faces the misfortunes of the protagonist, which elicit pity and compassion. Simultaneously, the audience also confronts the failure of the protagonist, thus receiving a frightening reminder of human limitations and frailties. Ultimately, however, both these negative emotions are purged, because the tragic protagonist’s suffering is an affirmation of human values rather than a despairing denial of them. See also tragedy.
