Dennett's argument, developed through Consciousness Explained (1991) and subsequent work, is that no such theater exists: there is no neural location where "the movie plays," no moment when experiences become conscious. Instead, multiple parallel processes in the brain compete, cooperate, and produce narrative threads that we post-hoc report as "what it was like." The Cartesian-Theater fallacy, Dennett holds, is the single most persistent error in everyday thinking about mind.

Discussions about whether a language model is conscious frequently presuppose the Cartesian-Theater picture: either there is or is not a unified experiential display inside the model. Dennett's position is that the question presupposes the wrong ontology. The correct question is
