RELATED TERMS: Diégèse and Diegesis
Plato and Aristotle define literary and dramatic genres in terms of the form of enunciation. They distinguish between diegesis, reported speech which articulates the writer’s authorial voice, and mimesis, in which the writer speaks, as if directly, through the characters.
This sense of diegesis differs from that developed by Etienne Souriau and Gerard Genette, who gradually rework its meaning entirely so that it comes to refer to the world of the story in its entirety.
