Physicalism posits that everything is physical, or at least supervenes on the physical.

Under this view, mental states including consciousness are the result of physical interaction within the brain.

If true, the exact replications of human physical brain states should yield identical conscious experiences, leaving no room for P-Zombie.

They simply cannot exist because their physical equivalence to human necessitates consciousness.

Mind-body dualism, on the other hand, argues that mental phenomena are non-physical and thus not bound by physical laws.

This perspective allows for the possibility of P-Zombie, as it suggests that physical replication alone might not replicate consciousness.

The mental and physical are distinct, and one can exist without the other.
