The hard problem of consciousness asks for an intelligible account that lets us see, in an intuitively satisfying way, how phenomenal, what it's like, consciousness could arise from physical or neural processes in the brain. Current theories cannot supply that link, a gap philosophers following Joseph Levine call the explanatory gap, and it remains genuinely contested whether the gap reflects a permanent limit on physical explanation or merely present theoretical shortcomings.
What would resolve this An account that closes the explanatory gap between physical or neural processes and subjective experience, or a widely accepted argument establishing that no such physical account is possible even in principle.
