It seems to me you could extend this argument to anything outside yourself. You "attribute such properties" as awareness to anything besides yourself because it "may behave like a creature [yourself] that is aware." Does this mean it "cannot be aware"? No? So where do you draw the line? I see no reason in principle why a "symbol" processing device could not, in appropriate circumstances, have intrinsic awareness rather than only seeming to have it. (Here it may be helpful to think of robots with onboard computers rather than just isolated computers.) It's true you may not understand the "meaning" inherent in the symbol processing until you are told what it is, but the meaning is there whether you understand it or not. Another point I will make once again is that the "symbols" computers really manipulate, bits, come in just two varieties. You could think of them as 0 and 1, red and green, on and off, or any two things that are different. Taken individually, they really have *no* meaning that amounts to anything, nothing that is "assigned" and that you have to "know" to make sense of processes that work with them--no meaning, that is, other than simply being different and distinguishable. And that is because, as I noted before, it is not the bits per se that are important but the patterns they form into in the course of the processing. There are further comments on this topic in my posting #21362. >And given tools like fMRI, it's quite illegitimate to restrict >our examination of a computer program versus a human being solely >to external behavior.

I don't think I'd be strongly inclined to argue the point, if the findings seemed reliable and complete, that is, I'd probably accept that the two did correspond. >...Nor is this an argument against the possibility that we might >build creatures that are aware.

All such machines, though, and natural people too, can be thought of as systems of particles that interact at the quantum level, which itself can be turned into an argument favoring computers. Again see my posting (and for a much more thorough discussion, Deutsch's *Fabric of Reality*). Mike Perry Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21474
