I alternate between thinking of the planet as home - dear and familiar stone hearth and garden - and as a hard land of exile in which we are all sojourners.

What have we been doing all these centuries but trying to call God back to the mountain, or, failing that, raise a peep out of anything that isn't us? What is the difference between a cathedral and a physics lab? Are not they both saying: Hello? We spy on whales and on interstellar radio objects; we starve ourselves and pray till we're blue.

Push it. examine all things intensely and relentlessly.

People who take photographs during their whole vacation won't remember their vacation. They'll only remember what photographs they took.

Out of a human population on earth of four and a half billion, perhaps twenty people can write a book in a year. Some people lift cars, too. Some people enter week-long sled-dog races, go over Niagara Falls in a barrel, fly planes through the Arc de Triomphe. Some people feel no pain in childbirth. Some people eat cars. There is no call to take human extremes as norms.

We wake, if we ever wake at all, to mystery, rumors of death, beauty, violence.

Our life is a faint tracing on the surface of mystery, like the idle curved tunnels of leaf miners on the face of a leaf. We must somehow take a wider view, look at the whole landscape, really see it, and describe what's going on here. Then we can at least wail the right question into the swaddling band of darkness, or, if it comes to that, choir the proper praise.
