Just a note to express my agreement. Re Searle: I heard him speak
"recently" (probably Dec. 1997, at ARNMD annual meeting) and was very
attentive, alert to hear his definition of "consciousness" if (for
once) he offered one. Indeed, early in his talk he alluded to the
problem of defining the term, but so far as I could tell did not
actually attempt it at any time in the rest of his talk. I asked a
colleague afterwards if he had heard a definition, and he said he had
not heard one.
It is mind-boggling that one can have such an exalted reputation and
be so much in demand as a speaker on this topic and yet shirk the
"Philosophy 101" basic task of defining one's terms before discussing
their supposed referents and pontificating on them.
His IMPLICIT definition does indeed seem to be something along the
lines you suggest it is: something carbon-based life-forms with DNA can
have and others can not. Armed with this implicit assumption he can
then go through the motions of demonstrating that a computer cannot be
conscious; unnecessary work (the conclusion predetermined) but
