Perception is individual, it is not art's usual shared image/object. Instead almost non-transactable. Possibly what Majoli means when saying "If our survival is tied to the capacity to perceive stability, vulnerability is made apparent at the root of--caused by our sense of sight." Because the optical instead flights. The realm of the biological, the immanent instead of the transcendent. Eye test patterns instead of television.
