He is not impressed by theories based on quantum theory. Alwyn Scott's Homepage Physics of Consciousness, by Stapp leads to the first part of a seven-part paper which is a valuable personal review of the topic. Physics of Consciousness by Henry Stapp, Lawrence Berkley Lab. A fascinating subject for me, which seems to be unusual among physical scientists, is the nature of subjective experience. It is such an essential component of life.
Science is objective.
Art is subjective. There is currently a huge resurgence of interest in the nature of consciousness, and the subject is attracting some of the big names in science. I'm not sure, but clearly some cutting edge scientists are eager to find out. It is the sort of quest where large cross-disciplinary teams are more likely to make progress than the individual genius as it calls for expert knowledge in so many fields in physical and medical sciences as well as other disciplines more commonly associated with the study of consciousness. For some, interest in consciousness extends to the exploration of altered states.
