In Consciousness Explained, Dennet proposed to replace the ubiquitous but bankrupt Cartesian Theater model with the Multiple Drafts Model. Drawing on psychology, cognitive neuroscience, and artificial intelligence, he asserted that human consciousness is essentially the mental software that reorganizes the functional architecture of the brain. In Sweet Dreams, he recasts the Multiple Drafts Model as the "fame in the brain" model, as a background against which to examine the philosophical issues that "continue to bedevil the field."
