None of the discoveries in neuroscience have suggested a novel
mechanism for consciousness. When neuroscientists consider
consciousness at all they consider the so-called neural correlates of
consciousness: processes A, B, C, D in the brain are associated with
experiences E, F, G, H. Processes A, B, C, D never involve anything
more than basic chemistry. Maybe there is stuff that hasn't been
discovered yet, but that is the current state of science.

It's difficult to continue this discussion if I've understood

But software cannot have any effect on hardware. Software is just a
method of organising hardware so that it will behave in a particular
way. A mountain is a mountain because of the movement of tectonic
plates, not because the spirit of mountain-hood forces the rock into a
conical shape.

But does consciousness make the matter in the brain behave in ways
that cannot be predicted by the laws of physics? If so, we should have
discovered this amazing fact by now. If not, then the brain's
behaviour could be predicted without reference to consciousness and
artificial brain components could be made that function the same as
biological components.

Reproducing the pattern of pixels and just the pattern of pixels would
reproduce the movie. The movie would still be what it is even if
no-one were around to understand it, just as three apples would still
be three apples even if there were no-one around to count them.

You reject the idea that consciousness is fundamental to function, but
you are OK about it being fundamental to matter. Why? On the face of
it there are several reasons why attaching it to function seems

1. Matter/energy is a thing, function and consciousness are not things.
2. A dead or frozen brain has the same matter but is not conscious.
The brain needs to function in the appropriate way to be conscious.
3. Consciousness seems to closely mirror function. I lift my arm, and
I have the sensation of lifting my arm. I don't have the sensation of
bones or neurotransmitters or the other things that go to make up my

These points are not proof that consciousness is fundamental to
function (as the fading qualia argument purports to be), but they are
