Mind/matter duality

[bennyboy]

Nobody yet has explained why a machine that functions exactly like the brain, but without subjective awareness, couldn't perform all the same evolutionary functions.

Are you asserting that a machine like the brain without subjective awareness could perform all the same evolutionary functions as a brain with subjective awareness? Perhaps I missed this, but if this is what you are claiming, I'd like to see your evidence for this claim. Until you provide some reasonable case for believing this is so, nobody has any obligation to prove the negative of it; what can be asserted without evidence can be dismissed without evidence. You can't just make arbitrary claims and suggest there is something wrong because nobody has disproved your claim. That's bullshit.

I'm not asserting anything except that if the brain is a purely physical mechanism, it should be able to perform all its functions without any added bonuses like the magi-wonderful creation of sentience.
