X-Message-Number: 30155 From: Date: Mon, 17 Dec 2007 10:53:26 EST Subject: feeling & consciousness Flavonoid asks where to find my discussion of putative potential computer consciousness. Mainly this is in my book Youniverse, which is available from the Immortalist Society (proceeds donated to IS research). Email _ (mailto:) . In extreme brevity, first of all, there is no agreed definition of consciousness and no current understanding of the physics and biology underlying it or characterizing it, hence no current way for an observer to decide whether an observed system is conscious. Secondly, I suggest that the essence of consciousness is feeling--the capacity for subjective experience--and again the physiology of feeling is not yet known, so we don't know whether an inorganic "brain" could support it. The pattern people or "upmorphists" assume as a matter of faith or as a postulate that thinking is computing and computing is thinking, and feeling is subsumed in thinking, but the evidence suggests otherwise. An algorithmic computer could match or beat humans in every intellectual activity, including predicting every thought and action of a human and thus making a robot behave outwardly exactly like a human, and still lack feeling, which means it would lack life as we know it. Your essence lies in your qualia, or subjective experiences. Personhood is defined by the existence of qualia, not by intelligence. A dog or cat or parrot is a "person" in this sense, while the most advanced computer is not, and perhaps no algorithmic computer can ever be. My (admittedly vague) suggestion is that a quale is a kind of standing wave in the brain, with extension in space and time. This also allows a reasonable basis for identifying with our past and future selves, since there is physical overlap between the current self and your predecessors and continuers. (This view also solves the homunculus problem, since a quale is not a representation of anything, but a thing in itself. You do not "have" qualia--you basically ARE your qualia.)
