Aristotle's Poetics establishes tragedy as the imitation of a serious, complete action of magnitude that produces catharsis through arousing pity and fear, grounded in unity of plot (mythos), causal completeness, hamartia (tragic error by an essentially good but fallible protagonist), peripeteia (reversal), and anagnorisis (recognition)—reframing mimesis, against Plato, as a cognitively and ethically valuable activity rather than deceptive imitation. This foundational theory of tragedy, within literary criticism and theory (aesthetics/poetics), was subsequently reinterpreted across a lineage of thinkers—Hegel (tragedy as collision of equally valid ethical positions resolved through dialectical synthesis in audience consciousness), Nietzsche (tragedy as fusion of Apollonian and Dionysian forces without resolution), Bakhtin (tragedy's unity contrasted with the novel's dialogic multivocality), realist critics (Richardson, Auerbach, Eliot, Hardy) who relocated tragedy into ordinary/domestic life, and materialist and postcolonial theorists (Williams, Eagleton, Steiner, Soyinka, Reese, Quayson) who reframed tragedy as politically, spiritually, and historically situated rather than a fixed formal category.
