Julian Jaynes was an American psychologist, best known for his book The Origin of Consciousness in the Breakdown of the Bicameral Mind (1976), in which he argued that ancient peoples were not conscious.Jaynes defines "consciousness" more narrowly than some philosophers. Jaynes' definition of consciousness is synonymous with what philosophers now call "meta-consciousness" or "meta-awareness" i.e. awareness of awareness, thoughts about thinking, desires about desires, beliefs about beliefs. This form of reflection is also distinct from the kinds of "deliberations" seen in other higher animals such as crows insofar as Jaynesian consciousness is dependent on linguistic cognition.
