This document summarizes several narrative structures and theories: - Todorov's narrative structure outlines an equilibrium, disruption, recognition of disruption, and new equilibrium. - Propp identified 8 character types (hero, villain, etc.) and 31 narrative functions that move stories forward. - Levi-Strauss suggested binary oppositions (good/evil, men/women, etc.) create conflict and drive narratives by being resolved. These binaries are culturally constructed.
