Another joy of Tallis' book is that the mystery deepens as our knowledge deepens, the two go hand in hand. And the resulting awe mounts up again when he reflects on how we do not have objective knowledge of the world, a view from nowhere, but subjective knowledge of the world, a viewpoint.I hadn't come across 'de-experiencing' before, but I can immediately use it: Wittgenstein was de-experienced in the Edgar Allan Poe department.
That is far more baffling and alarming, since 'aware of being located in a boundless world, we are not sure of our place in that world.' It is what Heidegger called 'de-experiencing': we see as subjects confronted by objects. This means, for example, that 'one can terrify with one's eyes not with one's ear or nose', as Wittgenstein noticed. Sight is always a two-way process: we can peep, point, press with our eyes and that can have a devastating effect on others.
