Seeing Picasso, Fixing Cezanne

The works of Pablo Picasso and Paul Czanne are based on particular ways of seeing. To understand these, we begin with ordinary vision. I open my eyes, and light streams through the lenses and forms pictures on my retinas. From these tiny pictures, my brain places before me a life-size, lens-projected, stable, upright, continuous picture of objects in space, the visual world. I recognize this world as the real world even though I know it is an event in my brain, a virtual reality. But how do those tiny pictures come to be the world around me? Part of my answer would be the imagined scaled to the visual world presence I have, in relation to which I see the visual world. I call what is an imagined generalized image of my face my visual ego.
