 Harman (1990) offers the transparency argument: We normally “see right through” perceptual states to external objects and do not even notice that we are in perceptual states; the properties we are aware of in perception are attributed to the objects perceived. “Look at a tree and try to turn your attention to intrinsic features of your visual experience. I predict you will find that the only features there to turn your attention to will be features of the presented tree, including relational features of the tree ‘from here’” (p. 39). Tye (1995) and Crane (2003) extend this argument to bodily sensations such as pain.
