If you talk about Zombie movies and ask, "Why would dead people be hungry? Why don't Zombies poop? Why wouldn't all of them rot and fall to pieces?" etc. etc. You would be demanding Real World logic to apply to a very unreal premise.
We can't mix the real with the unreal and make it logical.
Hi Terry,
There is more to zombies than meets the eye. Or is there?

Why do philosophers need zombies?
The concept is kind of a mind trick. Imagine a being that looks and even talks like a human. It goes through all the normal motions of a human and yet has no consciousness. And you would have no idea that it is not like you.
According to philosophers like David Chalmers, p-zombies are an argument against physicalism - the school of thought that everything that makes us human is ultimately derived from our physical characteristics.
Physicalism is based on the success of science in exploring the physical world. According to physicalists, we are essentially intricate arrangements of atoms. Behaviorists, a subset of physicalists, maintain that even all mental processes - thoughts, desires, etc - are just responses to the behaviors of others.
If a p-zombie that is exactly like us, except for the sense of self and consciousness, is logically conceivable, then this possibility could support dualism, an alternative view that sees the world consisting of not just the physical but also the mental.
