These papers on-line from the Journal of Consciousness Studies are all ten years old, but full of good ideas. Linked by a cross-hit on Brian Josephson, whose contribution here is a review of Roger Penrose “Shadows of the Mind”, and include references to Chalmers, GEB and qualia, amongst other things. Some good reading.
(Also linked Lindsay Beyerstein’s Majikthise in my blogroll thanks to the same cross-hit.)
