The designers designed and built a machine and that machine acted in the world and did what it did. Of course if it won, it beat Kasparov. The designers didn't play in the game, face the particular plays Kasparov made. The machine did and did what it did by brute data crunching as I recall, rather than by thinking about the game the way humans do. But so what? Whatever it did it still played against Kasparov and a more sophisticated machine MIGHT have accomplished the same end in a more human like way.

That you think magic must be invoked is interesting. He certainly isn't ascribing any of it to magic. Why do you think that is needed? If consciousness is a feature (or features) of a certain type of system there is nothing magical at work at all. However, there would be if we wanted to say it's an irreducible property in the world. In that case where does it come from and how does it manage to coexist with other classes of properties and even to interact with them? > He should give us a logical argument or another thought experiment -- > something with teeth -- to counter Searle's CRA. > He did (albeit not a formal argument as in a syllogism).

But I have already made it several times and I see it is having no impact. One more time perhaps? 1) If consciousness is irreducible to anything unlike itself (what isn't conscious) then if it isn't present in the CR among any of the CR's constituent processes then, obviously, nothing in the CR can bring it about. 2) But if consciousness IS reducible to something unlike itself (what isn't conscious) then there is no reason why the constituent processes of the CR should not be capable of bringing consciousness about in a more robust configuration. If the first is the case then the CR demonstrates that computational processes running on computers cannot cause consciousness BUT THAT IS ONLY BECAUSE OF A DUALIST PRESUMPTION of irreducibility. If the second is the case, then the CR does not demonstrate that computational processes running on computers cannot cause consciousness (whether they can or cannot based on empirical evidence). Why does Dennett call Searle a dualist? Is it just because he disagrees with Searle as you put it? No, because, if you look at the two statements above the first reflects the CRA, Searle's argument, and it is grounded in a dualist presumption (that consciousness is irreducible to anything unlike itself). So there is an argument here and, in fact, a fairly rigorous one. Here is how I put it earlier in these discussions to Joe: 1) If you think consciousness is irreducible to anything that isn't like itself (conscious), then you hold a dualist presumption regarding what consciousness is. 2) The only reason the CR might suggest a conclusion that what the constituents of the CR cannot do there they cannot do in any other configuration, is if you think that consciousness is irreducible as described in #1 above. 3) Searle thinks that the CR demonstrates that what the constituents of the CR cannot do in the CR they cannot do in any other configuration (see his CRA). 4) Therefore Searle holds a dualist presumption (whether he acknowledges it explicitly or not). This isn't name calling. It's to show something about the implications of his claims. Personally I have nothing against dualists and don't even consider dualism a pejorative term, contra some. I just think we ought to call a spade a spade and recognize what underlies claims like Searle's. SWM ========================================= Need Something?
