Conservationists have, I fear, adopted the pedagogical method of the prophets: we mutter darkly about impending doom if people don't mend their ways. The doom is impending, all right; no one can be an ecologist, even an amateur one, without seeing it. But do people mend their ways for fear of calamity? I doubt it. They are more likely to do it out of pure curiosity and interest.

The last word in ignorance is the man who says of an animal or plant, "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering.

Health is the capacity of the land for self-renewal.

This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. On a still night, when the campfire is low and the Pleiades have climbed over rimrocks, sit quietly and listen, and think hard of everything you have seen and tried to understand. Then you may hear it - a vast pulsing harmony - its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.

I love all trees, but I am in love with pines.

It is in midwinter that I sometimes glean from my pines... a curious transfusion of courage.

The modern dogma is comfort at any cost.
