In Science and Consciousness, a review of Jeffrey Gray’s Consciousness: Creeping up on the Hard Problem.
“Gray’s book is well worth the read. His coverage of models that address the hard problem of consciousness is reasonably complete. Gray is highly skilled at thoroughly critiquing each model (always finding both strengths and weaknesses). He gives the same constructive criticism to each model, in exactly the same measure he gives his own. His style is entirely fair-minded and refreshing.
I, for one, agree with most aspects of Gray’s comparator model wherein consciousness serves in late error detection, especially the next time a stimulus is presented. One potential point missed by Gray (but perhaps alluded to) is that consciousness may, in some instances, provide a representation of the stimulus-response. As Gray astutely argues in matters of brain, everything is a representation.”
