# Consciousness
Consciousness is subjective experience—the "what it is like" quality of mental states ([[Thomas Nagel]]). It encompasses awareness, perception, thought, and the felt quality of experience ([[Qualia]]). [[David Chalmers]] distinguished the "easy problems" (explaining cognitive functions) from the "hard problem" (why there is subjective experience at all). This remains one of the deepest puzzles in [[Philosophy of Mind]].
Major positions include: [[Dualism]] (mind and body are separate), physicalism (consciousness is physical), [[Functionalism]] (mental states defined by function), and panpsychism (consciousness is fundamental). [[Daniel Dennett]] argues consciousness is an illusion created by brain processes; [[Thomas Nagel]] and Chalmers argue it's irreducible. [[Patricia Churchland]] advocates for neuroscientific explanation.
