Unconscious peripheral perception transforms retinal images into spatial and bodily experiences. Peripheral vision integrates us with space, while focused vision pushes us out of the space and makes us mere observers.
[T]here are -- as I shall show -- images of matter, images that stem directly from matter. The eye assigns them names, but only the hand truly knows them. A dynamic joy touches, moulds, and refines them. When forms, mere perishable forms and vain images -- perpetual change of surfaces -- are put aside, these images of matter are dreamt substantially and intimately. They have weight; they constitute a heart.
