““our visuallydominated world sight is almost synonymous with understanding. We acknowledge light dawning by saying: ‘I see!’ The metaphor of vision suffuses our attempts to convey comprehension: we bring issues into focus, we clarify our views, we sight our objectives, we look into things. We accept the evidence of our own eyes. The conjurer turns the veracity of sight head over heels: now you see it—now you don’t. We find his tricks disturbing because we are so wedded to the truth of sight.””
