Why evolutionary theory contradicts materialism

Quote:Evolutionary theory not only fails to account for the putative emergence of consciousness from a non-conscious, material substrate, but it also outright contradicts materialism by implying that subjective states have causal powers in and of themselves, argues Dr. Oxenberg. His argument is explicit, conceptually clear, original, compelling, and we could not find a way to refute it. It is an argument not against evolutionary theory, but precisely based on it. Dr. Oxenberg then goes on to conclude that “the truth of evolutionary theory is consistent with a fully informed and rational spiritual faith.”
Quote:...What we would expect, on materialist assumptions, is that there would be no subjective states at all. Of course, we know this not to be the case. In the face of the undeniable fact of subjective states, then, materialism maintains that these states are mere ‘epiphenomena,’ i.e., irrelevant to the causal nexus of the material world. But this is just what natural selection shows is not the case. If subjective states were irrelevant to material causality, they would have no correlation with survival-relevant behavior. We would expect a random distribution of these states, and expect them to have no affect on, or association with, behavior.
But we do not find a random distribution of subjective states; rather, we find that positive (i.e., desirable) states are, by and large, associated with survival-promoting behavior and negative states with survival-threatening behavior. Again, this could only result from natural selection if these states can reach into the physical world and change it. But if they can, then this means the subjective—i.e., the non-material—must have physical efficacy. This altogether contravenes the assumptions of materialism.
The materialist would likely counter that these states are not merely subjective, but have material counterparts in the brain or nervous system. Neurological study leaves little doubt that this is so. On this basis, the materialist would argue that it is not the subjective quality of the state that affects physical behavior but its material, neurological counterpart. This would allow all causality to remain on the material plane. Fair enough. But then how to account for the fact that these subjective states have just these subjective qualities...
'Historically, we may regard materialism as a system of dogma set up to combat orthodox dogma...Accordingly we find that, as ancient orthodoxies disintegrate, materialism more and more gives way to scepticism.'
