Survey of the philosophy of consciousness covering the main theories and the explanatory gap.
Why it matters here
Pulls together the conceptual frameworks behind every empirical claim about consciousness.
Linked claims
Behaviour is not evidence of inner experience. We have no detector for consciousness in any system we did not already believe to be conscious.
The brain as transducer, not source — proposed by James, Bergson, Huxley. Compatible with neural correlates but harder to falsify.
The view that the universe as a whole is conscious — sometimes called cosmopsychism. Distinct from panpsychism (which puts mind in atomic matter) and from idealism (which says reality is mental).
The materialist / physicalist view: lesions, drugs, anesthesia, and imaging all show tight brain–mind coupling, and physical mechanism explains an enormous range of phenomena. Why neural activity feels like anything at all remains the open exception.
If consciousness is basic, the 'hard problem' dissolves. The cost is a major break with the standard physicalist picture.
From Berkeley to Kastrup: matter is appearance within a more fundamental mind. Coherent, ancient, contested.
Descartes' view that mind and body are two distinct substances that somehow interact. The most intuitive position; also the one neuroscience has worked hardest to discredit.
If basic matter has a hint of experience, complex brains can build complex minds. The 'combination problem' is the catch.
