philosophical zombie

A philosophical zombie is a hypothetical being that behaves exactly like a normal human—talks, reacts, and acts—but lacks conscious experience or inner awareness. In other words, it has no sentience or feelings, only outward behavior. This concept is used in philosophy to explore questions about consciousness: if a zombie can seem identical to a conscious person but has no inner experience, it challenges the idea that behavior alone shows consciousness. It helps examine whether consciousness is a separate, non-physical aspect of our being or just a product of physical processes.
