Glass Insanity

He was insane. And when you look directly at an insane man all you see is a reflection of your own knowledge that he’s insane, which is not to see him at all. To see him you must see what he saw and when you are trying to see the vision of an insane man, an oblique route is the only way to come at it. Otherwise your own opinions block the way. There is only one access to him that I can see as passable and we still have a way to go.
