Assess students' ability to analyze Bakhtin's concepts of heteroglossia and polyphony as applied to Dostoevsky's Crime and Punishment and The Brothers Karamazov: identify representative passages, explain how dialogic plurality and competing verbal-ideological voices function in each novel, compare their effects on narrative authority, character autonomy, and ethical discourse, and critically evaluate the explanatory strengths and limits of Bakhtin's framework using close textual evidence.
