Obviously in any system that does perception there will have to be different classes of knowledge. Talking about the different mechanics of acquiring such knowledge seems like an odd way to attempt to disprove something called "physicality". The question seems to be a mere quibble about the meaning of the word "knowledge". It presumes that there is something special about one of the ways people learn things. Does a recording video camera gain "knowledge" about the colour red when it records a scene with a red object in it? What, if anything, does the camera learn about the shape of a cube it sees? It can learn colour but it can't learn shapes. Should we conclude from this that shape is some sort of special knowledge outside of mere physicality?
