Philosophical zombies, or p-zombies, are hypothetical beings that are physically indistinguishable from humans but lack conscious experience. They behave like normal people, responding to stimuli and engaging in conversation, yet they do not have any subjective awareness or feelings. This concept is often used in discussions about the nature of consciousness and the mind-body problem. The idea of philosophical zombies raises questions about the relationship between physical processes and conscious experience. It challenges the notion that all mental states can be fully explained by physical states, suggesting that there may be aspects of consciousness that are not captured by a purely physicalist view of the mind.
