“It is vital that we avoid any hint of moral superiority in our dealings with one another in the environmental movement; if it developed into factionalism it would destroy us, as factionalism has destroyed so many other progressive movements in America.”

“If you hope for any sort of dialogue and unity with all factions on the vaguely leftist or radical side of politics, you must cease from silly verbal abuse. If you don't want it, then we go on as we are, fractious and impotent.”

“Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives as water and good bread. A civilization which destroys what little remains of the wild, the spare, the original, is cutting itself off from its origins and betraying the principle of civilization itself.”

“Devoted though we must be to the conservation cause, I do not believe that any of us should give it all of our time or effort or heart. Give what you can, but do not burn yourselves out -- or break your hearts. Let us save at least half of our lives for the enjoyment of this wonderful world which still exists. Leave your dens, abandon your cars and walk out into the great mountains, the deserts, the forests, the seashores. Those treasures still belong to all of us. Enjoy them to the full, stretch your legs, expand your lungs, enliven your hearts -- and we will outlive the greedy swine who want to destroy it all in the name of what they call GROWTH.God bless America -- let's save some of it.Long live the weeds and the wilderness yet!”

“There is a certain animal vitality in most of us which carries us through any trouble but the absolutely overwhelming. Only a fool has no sorrow, only an idiot has no grief - but then only a fool and an idiot will let grief and sorrow ride him down into the grave.”

“I doubt that my sense of personal freedom is any stronger than anybody else's. I'm happy to respect authority when it's genuine authority, based on moral or intellectual or even technical superiority. I'm eager to follow a hero if we can find one. But I tend to resist or evade any kind of authority based merely on the power to coerce. Government, for example. The Army tried to train us to salute the uniform, not the man. Failed. I will salute the man, maybe, if I think he's worthy of it, but I don't salute uniforms anymore.”

“The ugliest thing in America is greed, the lust for power and domination, the lunatic ideology of perpetual Growth - with a capital G. 'Progress' in our nation has for too long been confused with 'Growth'; I see the two as different, almost incompatible, since progress means, or should mean, change for the better - toward social justice, a livable and open world, equal opportunity and affirmative action for all forms of life. And I mean all forms, not merely the human. The grizzly, the wolf, the rattlesnake, the condor, the coyote, the crocodile, whatever, each and every species has as much right to be here as we do.”
