I really don't know why people have so much trouble now writing about religious faith. It is true that clichés can override more interesting impulses. But the desire to find meaning, to be generous, to live well in an ethical and spiritual sense, is so widespread that it should not seem alien to people when it is expressed in the terms of traditional religion.

I have spent my life watching, not to see beyond the world, merely to see, great mystery, what is plainly before my eyes. I think the concept of transcendence is based on a misreading of creation. With all respect to heaven, the scene of the miracle is here, among us. The eternal as an idea is much less preposterous than time, and this very fact should seize our attention.

Any human face is a claim on you, because you can't help but understand the singularity of it, the courage and loneliness of it. But this is truest of the face of an infant. I consider that to be one kind of vision, as mystical as any.

Many times when I stop working on a problem consciously, my mind continues to work on it below the surface. Often solutions come on me quite by surprise. I've learned over time to allow that to happen, rather than to feel that I can simply solve the problem by continuous, grueling effort.

I read things like theology, and I read about science, Scientific American and publications like that, because they stimulate again and again my sense of the almost arbitrary given-ness of experience, the fact that nothing can be taken for granted.

When the Reformation became established, one of the things that was a question between Catholicism and the Reformation traditions was whether there was a hierarchy of being. If you look at Thomas Aquinas, for example, you have hierarchies of angels and all the rest of it, and hierarchies even of saints and then subsaints - people who aren't quite there, that sort of thing. The Reformation rejected all of that and created a new metaphysics, in effect, that is not hierarchical.

It is an amazing thing to watch people laugh, the way it sort of takes them over. Sometimes they really do struggle with it . . . so I wonder what it is and where it comes from, and I wonder what it expends out of your system, so that you have to do it till you're done, like crying in a way, I suppose, except that laughter is much more easily spent.
