If one accepts materialism the conscious mind is essentially in denial of the reality that it is, ie mind. In other words it would be an unreality confirming reality, which is essentially self-refuting.
I'm always disappointed how often I see materialism so misunderstood by people who uphold a priori consciousness or other forms of Platonic thinking. To me, the statement above so blatantly begs the question about a priori consciousness that it ends up saying nothing at all of value.
I know quite a few materialists like myself. Contrary to the above statment's claim, we definitely are not
"in denial of the reality that it [the conscious mind] is, i.e., mind" (although I question what value such a simplistic tautology has). We just deny that it has
a priori existence prior to matter/energy. To us, the conscious mind is an emergent phenomenon of material complexity. Given an understanding of complexity theory, and the available physical evidence presented to us by the universe, it is a more reasonable philosophical position than positing a priori consciousness.
This seems to mean that if one accepts materialism, the conscious mind is completely deterministic and therefore a our consciousness is an illusion?
The participants to this discussion seriously need to read a primer on complexity theory which hopefully will suggest how
mind per se, emergent from material reality,
cannot be deterministic, even in principle. I recommend "The Cosmic Blueprint" by Paul Davies for its brevity and ease of reading.
