The history of consciousness and its origins fascinate me. It seems that either all life (and perhaps the universe itself) is “conscious” or, if false, then there existed an “Adam” who was the first human born with consciousness. These books propose other theories on this idea; they all deal with the brain and consciousness. I have not yet read them, as I am still in the process of reading Godel, Escher, Bach and the Tree of Knowledge.
