The gap
Even a complete functional account of a brain state can seem to leave open why it feels like anything at all.
What would count as explaining a feeling rather than only the behaviour that goes with it?
Philosophical questions about consciousness
Explaining how a brain discriminates, remembers and reports is difficult but recognisably scientific. Explaining why any of that is accompanied by felt experience is a different kind of problem, and it is the one that makes questions about minds, selves and machines resist confident answers.

Even a complete functional account of a brain state can seem to leave open why it feels like anything at all.
What would count as explaining a feeling rather than only the behaviour that goes with it?
The felt character of an experience appears hard to convey to anyone who has not had it, which either reveals something about consciousness or something about description.
Describe a sensation so that someone who has never had it would recognise it. Where does the attempt fail?
Experience is accessible in one's own case but inferred in every other case, and the inference cannot be checked directly.
What evidence actually persuades you that another person has an inner life?
A system can produce fluent reports of inner states without that settling whether any state is felt, so behaviour may underdetermine the answer.
What would a machine have to do—not say—before you took its experience seriously?
Psychological continuity, bodily continuity and narrative self-understanding can diverge, and each supports a different answer about persistence.
Which continuity would you have to lose before you stopped being the same person?
The self may be a persisting subject of experience or a construction that experience produces and then attributes to itself.
Is the self something that has your thoughts, or something your thoughts assemble?
