Document Summary
Qualia: the ways things seem to us; the raw feels; phenomenal, subjective or experiential properties: the way something, like a lemon looks, tastes, or smells. The knowledge argument fred: fred has better color vision than anyone on record, he sees two colors where we see one. He sees red1 and red2 what he says are two entirely distinct colors: fred can see at least one more color than we can. What is the new color / colors like? . No amount of physical information about fred"s brain and optical system tells us it follows that physicalism leaves something out . The knowledge argument mary: mary has lived her whole life in a black-an-white room. It seems just obvious that she will learn something about the world and our visual experience of it. But then it is inescapable that her previous knowledge was incomplete. Ergo there is more t have than that, and physicalism is false .
