I'm pretty sure that in later versions he is more explicit yet about the error that he thinks AI makes in trying to build real properties like intentionality out of the abstractions of functionalism or syntax, but I should keep them handy anyway, I'll get them ASAP. Josh From draft version of Minds, Brains, and Programs (1980) that you can find online, only the old copies seem to all redirect now to Cambridge Journals: I see no reason in principle why we couldn't give a machine the capacity to understand English or Chinese, since in an important sense our bodies with our brains are precisely such machines. ... "Yes, but could an artifact, a man-made machine think?" Assuming it is possible to produce artificially a machine with a nervous system, neurons with axons and dendrites, and all the rest of it, sufficiently like ours, again the answer to the question seems to be obviously, yes. ... "Could a machine think?" The answer is, obviously, yes. We are precisely such machines. ========================================= Need Something? Check here: http://ludwig.squarespace.com/wittrslinks/
