How could you possibly be an affective agent without knowledge? And how could anything ever use knowledge without perceiving it? Whenever anyone talks about philosophical zombies, I say “show me one, then” — until then I’m sticking with (what I see as) the scientific consensus, which is that we’re material like literally everything else is in the Actual, perceivable world.
The concept of p-zombies requires a soul, or other mystic forces. It just hides it. Materialists should reject the notion as inherently incoherent. Two things cannot be physically the same, where one is conscious and the other not. To think so, is to invalidate physics.
What would it be like to not be like anything?
