'seeing comes before words. the child looks and recognizes before it can speak. but there is also another sense in which seeing comes before words. it is seeing which establishes our place in the surrounding world; we explain that world with words, but words can never undo the fact that we are surrounded by it. the relation between what we see and what we know is never settled. the surrealist painter magritte commented on this always-present gap between words and seeing in a painting called the key of dreams.'
