Physicalist Vs. Anti-physicalist Theories Of Consciousness

Physicalist theories: Attempt to account for phenomenal consciousness in physical terms.

Anti-physicalist theories: Claim that the above is impossible.

Is one branch more conducive to valid scientific explanation?

Also consider reductive and non-reductive theories. Reductive theories attempt to account for phenomenal character in non-phenomenal terms - i.e. “complex system is nothing but the sum of its parts” - whereas non-reductive ones don’t.
