“imagine that in the Far Far Future there's a brilliant neuroscientist named Mary who for some reason is confined to a room in which everything appears in black and white...one day Mary is allowed to leave her room and the very first thing she sees is a plump Red Tomato now here's the question from this experience of the color red will Mary learn anything new”
