Reductionism in Art and Brain Science, Erick Kandel page 179, Zettel 139

Abstract art dares our visual system to interpret an image that is fundamentally different from the kind of images our brain has evolved to reconstruct. - Reductionism in Art and Brain Science, Erick Kandel page 179, Zettel 139
