If some sort of standing wave was associated with human or animal consciousness, say, and you had an artificial system that simulated every aspect of consciousness including the standing wave, though it lacked a real standing wave, the system might appear to be conscious in all respects. It may be that you could never "prove" it conscious, but I see no way in principle you could prove it was not conscious either. My response to this is to grant the benefit of the doubt. For example, a carefully constructed robot cat might seem to be a cat externally, and would have a carefully simulated cat brain internally. (Note that this would place it far beyond the mechanical ducks of the 18th century and like devices, which certainly had no onboard computer or other such interactive mechanism and were not at all simulating neural processes in the manner I am suggesting.) A creature like this, then, would appear to enjoy being petted and have other feline attributes, so I would naturally think of it as having real feeling, not just an imitation. Again, I see no way, in principle, of ever establishing scientifically whether you should think of such a creature as "really" conscious or just a good, but stone dead, imitation. This, of course, assumes no future scientific or conceptual breakthrough or other happening that would radically change our thinking. Qualia, then, *would* arise from information processing as such. You can't prove it, but then, you can't prove that anything besides perceptions exists. To me, it seems exciting and wonderful that information processing should suffice for feeling, plus, I think, offering greater prospects for future survival and enjoyment, when technology is more advanced. I accept the principle as a working hypothesis for now, and leave it at that. Mike Perry Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21338
