“If the end does not justify the means - what can?”

“To all accusations of excessive development the administrators can reply, as they will if pressed hard enough, that they are giving the public what it wants, that their primary duty is to serve the public not preserve the wilds. "Parks are for people" is the public relations slogan, which decoded means that the parks are for people-in-automobiles. Behind the slogan is the assumption that the majority of Americans, exactly like the managers of the tourist industry, expect and demand to see their national parks from the comfort, security and convenience of their automobiles.Is this assumption correct? Perhaps. Does that justify the continued and increasing erosion of the parks? It does not.”

“All governments need enemies. How else to justify their existence?”

“Simply because humankind have the power now to meddle or 'manage' or 'exercise stewardship' in every nook and cranny of the world does not mean that we have a right to do so. Even less, the obligation.”

“Man is a gregarious creature, we are told, a social being. Does that mean he is also a herd animal?...Are men no better than sheep or cattle, that they must live always in view of one another in order to feel a sense of safety? I can't believe it!”

“Certainly, I want to capture the reader's attention from the beginning and hold it until the end: that is half the purpose of my art. The other half must be to tell my story in the most honest way that I can.”

“If the life of natural things, millions of years old, does not seem sacred to us, then what can be sacred? Human vanity alone? Contempt for the natural world is contempt for life. The domination of nature leads to the domination of human nature. Anything becomes permissible. We return once more to the nightmare cultures of Hitler, Stalin, King Philip II, Montezuma, Caligula, Heliogabalus, Herod, the Pharaohs; Christ sacrificed himself in vain.”
