X-Message-Number: 14745 From: Date: Fri, 20 Oct 2000 12:40:28 EDT Subject: Clark's questions Again, this is mostly for newcomers who may not yet be sick of this go-round. John Clark (#14739) writes: >it would be nice if it [the "self circuit"] shed a little light on something, anything. It offers, as I have explained, a possible new notion of how subjective experiences arise. It could be wrong, of course, but it is not vacuous. If feeling stems from modulated standing waves of some sort in the brain, then we are no longer restricted to an apparent choice between "homunculi" and "emergence." Clark goes on: > Explain why a standing wave creates subjectivity. Maybe I'm a little thick but it's >not obvious what one has to do with the other. The physical basis of feeling has to be something which is not just a symbol or a representation of something else; it has to be the thing-in-itself or ding-an-sich. Experiment will decide whether my idea is correct, if we find the standing waves (or something similar) and correlate them with reported feelings. >And to repeat, a standing wave of what? To repeat, electrical or/and magnetic or/and chemical waves. Then: > The Turing Test doesn't proved anything, it's just the best thing we have, in fact it's the only thing we have to study consciousness other than our own. For the umpteenth time--obviously not true. Study of consciousness is not restricted to (a) external observation of gross behavior or (b) introspection. Studies of internal brain functions, and their correlation with reported subjective states, is proceeding apace. Next: > And if the self circuit does things other than generate a feeling of self as you say >then it makes as much sense to call it a self circuit as it does to call the RF >generator in my radio a Beethoven circuit. The radio receiver converts radio signals back into sound. The radio doesn't know or care whether the sound is Beethoven's music or somebody's fart. The self circuit, on the other hand (and it must exist, whether a standing wave or something else), besides interacting with other aspects of the brain, CONSTITUTES feeling. Since it does (or is) something unique and uniquely important, it certainly deserves a name. Then: >so it would be easier to make a conscious computer than a non conscious one. [Because it "could provide rough-and-ready or quick-and-dirty solutions"] Non sequitur. Elegant solutions are not necessarily the first developed, either by nature or by people. And: > I seem to remember Marvin Minsky saying that we already have sentient >computers but we don't have intelligent ones. I don't know it that's true or >not but I certainly can't prove him wrong. Minsky, Dennett, and a few others claim to have made inroads on the problem of sentience, but I (and most others) do not agree. In effect, they merely restate the "emergence" notion of sentience--that when an information processing system becomes complicated enough, somehow sentience is just there. That doesn't cut the mustard. Robert Ettinger Cryonics Institute Immortalist Society http://www.cryonics.org Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=14745
