Walter: if you have to assert consciousness is reducible to its material ground, then it isn't really. "Light in meat" is just another way of referring to the miracle that is meat spontaneously generating such a thing as awareness. It really comes down to perspective.
Science is locked within the horizon of its presumed objectivity; neurological activity =/= consciousness, any more than the harmonics of a Beethoven piece is the music proper.
At best science can only offer a formal definition of consciousness, as an emergent property of such-and-such systems in such-and-such organization (which I never disagreed with) but that isn't, fundamentally, what consciousness actually is: the a priori condition of even being able to have such a concept of objectivity, empiricism, reality, etc. in the first place. That is, the very observer doing the observing in the first place. Anything beyond that is just a structural description that in no way could supersede consciousness in its naked actuality.
Also I've been pretty clear that Buddhists, among others, have already debunked naive notions of the self thousands of years ago.
tleilaxu: you're mistaking the empirical ego with non-self/buddha-nature. The goal is not to kill the self but everything we erroneously assume to be the self. The desire for nothingness is an impediment on the path as much as the desire for some kind of celestial existence. The stock "why don't Buddhists just kill themselves?" argument comes from what can only be a superficial reading of Buddhist doctrine.
I urge you to study these traditions closely if you have any interest in them at all. There's really nothing new science is telling us that a intuition, arduous study, and introspection hasn't already revealed.
