A philosophical zombie or p-zombie is a hypothetical being that is indistinguishable from a normal human being except that it lacks conscious experience, qualia, or sentience. When a zombie is poked with a sharp object, for example, it does not feel any pain. While it behaves exactly as if it does feel pain (it may say "ouch" and recoil from the stimulus, or tell us that it is in intense pain), it does not actually have the experience of pain as a putative "normal" person does.
Idea actualizes questions of mind-body dualism (or monism) and is put forward by David Chalmers. His argument is that it seems very plausible that such a being could exist because all that is needed is that all and only the things that the physical sciences describe about a zombie must be true of it. Since none of the concepts involved in these sciences make reference to consciousness or other mental phenomena, and any physical entity can be by definition described scientifically via physics, the move from conceivability to possibility is not such a large one.
"I had this idea—which was a stupid idea—of doing a remake of a film called I Walked With A Zombie by Jacques Tourneur, I decided to make something around my memory of that film; a film that has zombies, volcanoes, ghosts, crazy women, dogs, various strange nights, a lot of confusion and mystery. You will see that it's not at all like I Walked With A Zombie; it's something else." (Pedro Costa about "Casa de lava")
