If only Bush and Cheney had an ant farm
Nobel prize winner Lord Edgar Adrian (1932) talked about the great advantage of distance receptors, referring to our receptivity for sight and sound and emphasizing their sensory advantages over other senses like touch and pain, to give us advanced warning and knowledge of the objects around us; of course vision is the supreme receptor system in this regard, not only because light is fast and gives us visual information about objects far away, but also because our remarkable visual system can detect things under extreme conditions of light and dark allowing us to have at least some visual capacity for the environmental light excursions cyclically present on the surface of the earth. But vision has another meaning which we use regularly, when we say someone had enough vision to put these principals into our constitution. The vision we refer to describes our perceptive skills and obviously reflects not just our intrinsic visual skills, but our capacity to reason, plan and execute, a kind of longitudinal vision or a special line of sight. Just as our survival from a predator requires quick and immediate action and depends on our distance receptors, our vision and perception of issues and circumstances are no less important for survival of our culutre, no less predictive of our future as a society, yet it demands from us a more contemplative approach, a different kind of vision. But vision, capturing quanta, here too plays a role, but more as visual memory, an indelible part of our brain architecture that forces on us a construct of the world, one with a visual, identifiable component. Half our brain cells can be activated by light, so our memory is rich in visual context. When we say we are visual animals, in reality we mean that we have more than just the powers of detecting light. We do more than see, we can foresee too.
