Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!

I'm a believer in belief. Faith is something that works - it causes people to do things, it has results. It's an intangible, indefinable, very real thing. And it moves people, sometimes to atrocity. And sometimes to survival.

I can't see that Danish episode as an adventure, or a crisis survived, or a serious quest for anything definable. It was just another happening like today's luncheon, something I got into and got out of.
