X-Message-Number: 14727 From: Date: Wed, 18 Oct 2000 13:08:43 EDT Subject: more explanations John Clark (#14716) repeats a couple of ancient questions, so I'll repeat the answers for the benefit of newcomers. First he asks how my suggestion about standing waves and the self circuit answers any questions, in particular about duplicates as self. I have never said the self circuit addresses all the philosophical problems such as identity of duplicates. It is simply a possible mechanism (very vague and general at this point) to explain subjectivity, i.e. feelings or qualia or experiences. Several philosophical problems remain open. John also asks, yet again, ignoring my previous answers, how evolution could have produced the self circuit if it "doesn't affect behavior"--and again mixes up and drags in behaviorism and the Turing Test. First, the Turing test is baloney in its own right and on its own terms. It is neither necessary nor sufficient to prove sentience. A non-sentient system might easily fool an observer, and a sentient system might easily fail the test. The self circuit DOES affect behavior and improve chances of survival--even though primitive "living" organisms may lack it or lack some aspects of it. It could provide rough-and-ready or quick-and-dirty solutions to problems of living, bypassing complicated calculations. "Smell good--eat." "Smell bad--me outa here." Could an unfeeling automaton develop behavior similar to that of a sentient organism? Certainly. We already have examples of computer programs that no one claims to be sentient, yet which (in limited areas) can fool those interacting with them. The automaton might also substitute speed of processing for the efficiency of the self circuit. Much more likely, however, the living (feeling) being will act differently--more efficiently in some ways, less efficiently or even pathologically in other ways. Next question (also from Henri Kluytmans)--exactly what is my suggested standing wave, or set of standing waves? It's presumably three dimensional, and may involve electric currents, magnetic fields, and chemical fields. But that's not my department--I don't have the brains or the time to figure it out. I'm just a big-picture guy. Henri Kluytmans also asks: >What was the scientific motivation for introducing such a model of standing waves? The universally recognized "hard problem" in neuroscience or cognitive science is accounting for subjective experience in objective terms. Nobody has done it, or come close. I think this opens a path. On another topic, Mr. Kluytmans pushes the "information-processing-is-everything" point of view. But I think he sometimes confuses what is necessary and what is sufficient, what is substantive and what is merely descriptive. Everything important that the brain does (everything that happens anywhere, in the view of some) can be regarded as information processing. But it does not follow that any old isomorphism is "just as good" or "the same" as the original. No matter how high the fidelity, in general the map is not the territory, except for restricted purposes.
