Extract
What has belief to do with perception? Some contemporary philosophers have suggested that one's perceiving an object entails one's having a particular perceptual belief, not just some belief or other, about that object. N. R. Hanson, for instance, has illustrated the present view, with respect to visual perception, as follows:
What is it to see boxes, staircases, birds, antelopes, bears, goblets, X-ray tubes? It is (at least) to have knowledge of certain sorts. … It is to see that, were certain things done to objects before our eyes, other things would result. … To see an X-ray tube is at least to see that, were it dropped on stone, it would smash. … Seeing a bird in the sky involves seeing that it will not suddenly do vertical snap rolls; and this is more than marks the retina. (Hanson 1958, pp. 20–21)
