Sometimes a man can become possessed by a vision.  Perhaps it makes
no sense to anyone else; perhaps it is a revelation to everyone.  Yes,
this man will say to himself, this is the way the world is supposed to be.
This is how I am supposed to fit into it.  He will know, like a man trying
on shoes, that he has finally found a pair that will serve him for a very
long walk indeed.  So he begins, one step at a time.
