Document Summary
She"s known about color vision although she"s always seen everything in black and white. She knows the theory behind color perception without actually experiencing it. So she learns the experience of seeing color when she sees color for the first time. Conclusion: there are things that we cannot explain through words, it must be first hand experience to understand it. P1: it is not possible to com o know what it is like to see red on the basis of physical facts. P2: but there is a fact about what it is like to see red. C1 (intermediate conclusion): so some facts cannot be known on the basis of knowledge of the physical facts. P3: if a fact is reducible to physics, then it"s possible to know it on the basis of knowledge of the physical facts. Conclusion: not all facts are reducible to physics. The conclusion is what we"re trying to establish, but we start with the premises.
