Mind you, I am not saying this is a substitute for careful analytic refutation of Chalmers’s thesis. System 1 is not a substitute for System 2, though it can help point the way. You still have to track down where the problems are specifically.
Chalmers wrote a big book, not all of which is available through free Google preview. I haven’t duplicated the long chains of argument where Chalmers lays out the arguments against himself in calm detail. I’ve just tried to tack on a final refutation of Chalmers’s last presented defense, which Chalmers has not yet countered to my knowledge. Hit the ball back into his court, as it were.
But, yes, on a core level, the sane thing to do when you see the conclusion of the zombie argument, is to say “That can’t possibly be right” and start looking for a flaw.
