At first glance your thread will likely get laughed at and people will shrug you off, but I simply do not know how anyone can adopt a naturalist perspective and not agree that humans are just machines ("chemical scum"). You cannot cherry pick if you are a naturalist and yet I manage to see people repeatedly attempt to inject their own belief system into what they call "naturalism". Things they throw around but do not fit within the tenets of their professed belief:
Free will (define it -- soft determinism doesn't count)
Mental causation (is it not inert if the physiological is all that matters?)
Consciousness (as something non-illusory, a byproduct)
Qualia (measure this in scientific terms or else it doesn't exist)
Responsibility for actions (in a cause and effect deterministic system, I don't know how you could *ever* say this exists or at least the individual has any "personal" responsibility)
I am a dualist and I respect the naturalist's right to an opinion, but I question whether they fully appreciate the view they advocate or whether it is adopted for some other reason(s).
Causality and the existence of consciousness are two separate issues. You can have consciousness (as defined by the existence of qualia) in a fully determinate universe. Science doesn't necessarily preclude qualia either: It's not possible to give a physical account of economic laws even though they we can empirically verify they exist. To deny qualia is to deny the value of empirical experience, which in fact seems contrary to the premise of science.
Contrasting social sciences (so-called "economic laws") with something that almost every sane person on earth asserts the existence of (not
too many people dispute the existence of consciousness) is not the greatest choice of approach IMO.
Anyways:
Science can know your own mind better than you can. At least, that is the truth according to Dennett, friends and fans. If that is true, and if you cannot measure qualia -- indeed if there are no laws* or functions*, nor is there any way to explain the 'indexicality' that you experience -- then what really makes you believe it exists at all? What makes you think consciousness exists as something non-illusory?
Is "empirically verifying they exist by
experience" not an appeal to intuition? Is that not a rather weak argument, if not outright circular reasoning itself ("qualia exist because my experiencing of quale says so...")
Is that 'scientific'?

To borrow from Kripke: Is a stimulated c-fiber the same as thing as 'pain'? Can the stimulated c-fiber exist
without 'pain'?

Are you aware of David Chalmer's theory of "non-reductive materialism" with regard to consciousness? I would suggest reading his book The Conscious Mind.

Coincidentally enough the day you posted that I had been re-reading sections of my copy. I do not agree with the positions he advocates although he makes the case for them very convincingly.
(* When I say no laws or functions of qualia, I mean the experience of 'what it is like', not the corresponding physiological happenings.)
