X-Message-Number: 21349 From: Date: Wed, 5 Mar 2003 11:09:56 EST Subject: Rosetta etc --part1_f3.29446323.2b977b54_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit 1. Thomas Donaldson seemed to think that I deny the possibility of feeling in an inorganic system. Actually, I don't even deny the possibility that isomorphism is everything--I only say that it is unproven and highly dubious. Certainly there is a possibility that some anatomical/physiological feature analogous to the self circuit (or whatever it is that allows feeling in organic creatures) might allow feeling in an inorganic system. But this remains to be seen, and the obvious first requirement is that we understand what is happening in ourselves. 2. Thomas also seems to say that mere computation can never constitute feeling, because we need semantics as well as syntax, and computer-generated numbers require interpretation. I have stressed this too, and recently--but in the past have also noted the (remote?) possibility that sufficiently large and consistent systems might be unambiguous, capable of only one interpretation. The example I used was that of an artificial language for conversing by radio with intelligent aliens. In general, no one can learn or decipher a language without help--a Rosetta stone or some other hints, even with human languages. But various people have shown how one could build up an artificial language in such a way that eventually any intelligent being could interpret it unambiguously, although at each stage there would be limitations on the range of expression.
