on cezanne and seeing

Posted: October 8, 2009 in All and Sundry

We know that Cezanne was right. Our vision begins with photons, but this is only the beginning. Whenever we open our eyes, the brain engages in an act of astonishing imagination, as it transforms the residues of light into a world of form and space that we can understand. By probing inside the skull, scientists can see how our sensations are created, how the cells of the visual cortex silently construct sight. Reality is not our there waiting to be witnessed; reality is made by the mind.” — from Proust is a Neuroscientist by Jonah Lehrer, 2007
