That way, you would get an "intelligent" machine at reasonably low effort. :-) Back to seriousness: I don't see that the frequently occurring argument that Searles has no concept of thinking, understanding, intelligence does lead very far. The problem is that nobody has such a concept. There are some properties and results of it which can be described, some of them, like memorizing, recalling from memory, comparing, counting and computing can be isolated and simulated by several machines, such as books, meters, calculators, and, most general, computers. Some time ago, one might have believed to be close to definitely solving the problem of building a thinking machine when getting one giving reasonable answers when asked for the cubic root of an arbitrary number. Nowadays, since that's performed by pocket calculators much faster and more reliable than every human being could ever do it, the goal seem farther away then ever estimated. Remember the ability of distinguishing an italic 'a' from a pica one, a problem which seemed even not to be one, then. Something heretic: I bet that it will be possible earlier to reproduce a living (even human) being from the (then) deciphered DNS than building a machine even passing some kind of Turing test (though I doubt that would be the breakthru point). > Greg, lee@uhccux.uhcc.hawaii.edu regards, es
