David Chalmers introduced the notion of a philosophical zombie. This is an entity that is physically identical to a human person, but lacks consciousness. His goal was to refute materialism, by showing that physical information alone isn't enough to explain consciousness.
In this formulation, a zombie looks and acts identical to a regular conscious human: if you talk to it, it replies as a person would. If you poke at it, it will *say* that it feels pain, even though in reality it experiences no pain (because it lacks internal experiences at all). It will look at a painting and exclaim about its beauty while actually having no consciousness or experience of beauty at all.
Others, such as Daniel Dennett, have challenged this notion, claiming it is internally inconsistent and assumes its conclusion. They argue that anything *physically* the same as a person would necessarily have the same consciousness as a person. Dennett claims that the fact that a zombie reacts *in all situations* exactly as a conscious person would is enough to say that zombie is, in fact, conscious.

What do you think? Are philosophical zombies a coherent concept? Are they a good argument for dualism?
