I consider the integrity of the material to be of greater value than any message I might want to get across.

There is a sense in which we are all each other's consequences

Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed ... so that never again can we have the chance to see ourselves single, separate, vertical and individual in the world, part of the environment of trees and rocks and soil, part of the natural world and competent to belong in it.

If the national park is, as Lord Bryce suggested, the best idea America has ever had, wilderness preservation is the highest refinement of that idea.

How much wilderness do the wilderness-lovers want? ask those who would mine and dig and cut and dam in such sanctuary spots as these. The answer is easy: Enough so that there will be in the years ahead a little relief, a little quiet, a little relaxation, for any of our increasing millions who need and want it.

... I was reminded of a remark of Willa Cather's, that you can't paint sunlight, you can only paint what it does with shadows on a wall. If you examine a life, as Socrates has been so tediously advising us to do for so many centuries, do you really examine a life, or do you examine the shadows it casts on other lives? Entity or relationships? Objective reality or the vanishing point of a multiple perspective exercise? Prism or the rainbows it refracts? And what if you're the wall? What if you never cast a shadow or rainbow of your own, but have only caught those cast by others?

If you're going to get old, you might as well get as old as you can get.
