Todorov suggests there are 5 stages of narrative: equilibrium, disruption of equilibrium, recognition of disruption, attempt to repair disruption, and new equilibrium. These stages are represented in a diagram with arrows showing the progression. Different genres will show these stages differently. Levi-Strauss believed narratives are based on binary oppositions like good/evil and male/female that create structure and meaning. However, this can lead to problematic hierarchies. Barthes discussed how narratives create enigmas to engage the audience in deriving meanings and making assumptions. Propp identified character functions like heroes, villains, dispatchers, and donors that recur across folktales.
