We present evidence, summarize it when we can, and offer the supporting/critiquing sources to our users. Our position is that more information is a good thing, that open-minds are better than closed ones, and that rather than insisting on an exclusive dichotomy of orthodoxy v. mind-body, we bring the two together under the banner of inclusive, evidence-based science.
I looked over your website, but can't say that I agree with your description. What you talk about is similar to Maxwell's Demon. Physicists knew that perpetual motion machines didn't work and that there was no type of machine that could deliver free energy. But then you had Maxwell's thought experiment in 1872. It didn't move physics or science forward. It didn't do anything practical. It provided nothing in terms of theory or explanation. It only existed because until Shannon's information theory in 1948 there was no simple refutation of it. The things on your website are similar. Except for a few on the fringe, consciousness is assumed to be solely a brain phenomenon. This assumption is based on boilerplate common sense such as the fact that rocks and plants exhibit nothing that can be considered reasoning. All reasoning organisms have brains. But your site doesn't seem to deal with this point honestly. Rather than mentioning rocks or plants it asks:
"To what extent are animal minds different from human minds?"
If you are limiting the scope to only things with brains then you've pretty much already made the assumption that dualism is false, regardless of how you dress it up. It would be like if I claimed that a computer program was not related to processors but was actually some separate, mystical function. And then for some strange reason the only examples of a running program that I could mention all involved processors.
I'm aware that cognition does not seem to be explainable in terms of computational theory, but this is where you draw an imaginary line:
"... while others offer cognitive theories of consciousness whereby conscious mental states are reduced to some kind of representational relation between mental states and the world.
Could an appropriately programmed machine be conscious?"
So, you've already made the assumption that either the computing theory of mind is true or dualism is true. However, both can be false. Consciousness can potentially be explained by a theory that is not limited to language theory or dualism. But this is not dealt with honestly:
"The two broad, traditional and competing theories of mind are dualism and materialism (or physicalism). "
These are not competing. All evidence, experience, theory, and testing supports materialism. The only thing dualism has in its corner is that like Maxwell's demon there is yet no published theory that easily refutes it. You have a section on dualism, a rather large section, but no equivalent section for materialism. Why is that? And, your claim that you represent both sides can be falsified with your own sites artificial limitations on balance. You explain every type of dualism you can think of and then:
"Materialists are aware of these dualist replies and sometimes invoke Ockham's razor and the importance of metaphysical simplicity in arguments to the best explanation. (See Churchland, 1988, p. 28). Other materialist responses will not be considered here."
But even for the arguments you allow, you constantly use false equivalence:
"The relationship between consciousness and brain processes leaves the materialist with a causal mystery perhaps as puzzling as that confronting the dualist."
You also include things like this:
"Another argument for dualism claims that dualism is required for free will."
You don't even mention that Dennett disagrees with this argument or that almost everyone does as well. Where is the balance?
