In the Hour of the Wolf
Which is to say the hour of acute insomnia, all of the contingent facts about me are sinister.
My left thumb is double-jointed. I had a tonsillectomy at age six. I once flew upside down in a Yak-52.
Any contingent fact about me is like the contents of a black trash bag that lies in a landfill. The mountain of trash bags is nearly, but not quite yet, complete. A cherry at the top of this sundae will be most sinister, for what it portends, which is a completed life.
Compare and contrast facts that are necessary, logical, mathematical, geometrical. (The analytic philosophers were obsessed with the distinction.) Without the contingency, I can take comfort in them.
So I broke the spell of the Hour of the Wolf not by counting sheep (as the wolf himself might), but by repeating to myself that C = piD. The circumference of a circle will always be equal to its diameter times 22/7. If I grasp hold of this and never let go, I thought, it may carry me off to a forever future, one free of contingency.
