If we knew everything about how the brain works, would we knew everything about consciousness?
Imagine super-scientist Mary. She lives in future. She knows everything about colour perception. But unfortunately she grew up in black and white room and she’s never seen colours. Some day she come out of her room and see green grass and blue sky. Would she learn something more about colour perception? Intuitively we’d say “yes”. But if it’s true then some part of consciousness lacks scientific explanation.
Dmitry Ivanov and Alexander Kaplan discussed the issue within a mutual project with Postnauka “Philosophy of mind from A to Z”.
