Religion: science, lawfulness, a (the?) god The Godless assumption ---------------------------------------------------------------------- Date: Thu 18 Aug 88 10:15:08-PDT From: George Cole Subject: Sensory/Abstract Reasoning and Parallel Thinking Two points I'd like to respond on: Sensory/Abstract Reasoning and Parallel Thinking. Driving a car (or martial arts) at an advanced level clearly involves "compiled" kinesthetic behavior coupled with sensory processing (in plain terms, eye-muscle coordination), plus advanced symbolic reasoning coupled with the same sensory processing (predicted paths of other vehicles from both physics and "rules of the road" and estimated intent. In commuter driving the abstract reasoning can reach quite high levels where the entire traffic pattern is perceived -- how many experienced commuters can spot the tourist who is "interfering" with the norm? The point I want to emphasize is that the symbolic reasoning is at a very high level, going beyond "stop at red light" rules to "the intent of the red car is to reach the exit requiring the blue truck to slow requiring that lane to slow with a high probability of some jackass swerving one lane over requiring that lane to react -- so I'm moving over to the fast lane to ease the potential congestion". This is one type of parallel cogitation -- but it can be argued that it actually is a learned and advanced compilation of processing into multi-level coordinated behavior, i.e. there really is only one reasoning process that simply has manifold layers capable of distinct, need-specific interpretation. True parallel cogitation either is unconscious or reflective: when you are aware of your reasoning as it progresses, isn't that parallel cogitation? And how many times have people solved problems in the background as they coped with their daily rush of events? My two-cents suggestion is that people engage in a great deal of parallel processing, using their innate "multiprocessor" capacity. Since it is harder to devise integrated algorithms than serial ones, most of the parallel processing will be of different "types" of reasoning (logical and emotional, physical and logical, visual and auditory, imitative vocal and creative mathematical, etc.). When integrated parallel processing has had a positive survival value (i.e. sensory-muscular coordination) we should find that behavior demonstrated. George S. Cole, Esq.

I don't think much of the argument, and suspect that the answer depends on what you mean by "thinking". For example, while reading your message and planning my reply, I was extemporising on a soprano recorder (not at all well, I hasten to add). Were both of those activities "thinking"? We can attend to 2..4 musical parts at once without switching between them, keeping straight which sounds belong to what part and what patterns are being formed. But does that count as "thinking"? And does "different" mean "unrelated" (perhaps processing information from different senses) or "conflicting" (perhaps trying to generate speech for two different topics). ------------------------------ Date: Thu, 18 Aug 88 12:57 O From: Subject: science, lawfulness, a (the?) god Distribution-File: AILIST@AI.AI.MIT.EDU In AIList Digest V8 #54, T. Michael O'Leary presents the following quotation (without mentioning who originally wrote it): > >Science, though not scientists (unfortunately), rejects the > >validity of religion: it requires that reality is in some sense > >utterly lawful, and that the unlawful, i.e. god, has no place. I would say that a God needs not be unlawful. A counterexample of some kind could be a line by Einstein: I think he said that the regularity of the structure of the universe reflects an intellect. (I cannot remember the exact form of the quotation, but I think the idea was this.) --- Andy ------------------------------ Date: Thu Aug 18 10:32:01 EDT 1988 From: sas@BBN.COM Subject: The Godless assumption FYI, for those who had trouble with Mike Dante's comment: I don't see that as any excuse for being a Luddite in either field. a Luddite is one who smashes machines.
