“What do we know? What do we really know? He licks his dried cracked lips. We know this apodictic rock beneath our feet. That dogmatic sun above our heads. The world of dreams, the agony of love and the foreknowledge of death. That is all we know. And all we need to know? Challenge that statement. I challenge that statement. With what? I don't know.”

“We know so very little about this strange planet we live on, this haunted world where all answers lead only to more mystery.”

“The love of wilderness is more than a hunger for what is always beyond reach; it is also an expression of loyalty to the earth, the earth which bore us and sustains us, the only paradise we shall ever know, the only paradise we ever need, if only we had the eyes to see.”

“Why can't we simply borrow what is useful to us from Buddhism, Hinduism, Taoism, especially Zen, as we borrow from Christianity, science, American Indian traditions and world literature in general, including philosophy, and let the rest go hang? Borrow what we need but rely principally upon our own senses, common sense and daily living experience.”

“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!”

“A man could be a lover and defender of the wilderness without ever in his lifetime leaving the boundaries of asphalt, powerlines, and right-angled surfaces. We need wilderness whether or not we ever set foot in it. We need a refuge even though we may never need to set foot in it. We need the possibility of escape as surely as we need hope; without it the life of the cities would drive all men into crime or drugs or psychoanalysis.”

“Our institutions are too big; they represent not the best but the worst characteristics of human beings. By submitting to huge hierarchies of power, we gain freedom from personal responsibility for what we do and are forced to do - the seduction of it - but we lose the dignity of being real men and women. Power corrupts; attracts the worst and corrupts the best. ... Refuse to participate in evil; insist on taking part in what is healthy, generous, and responsible. Stand up, speak out, and when necessary fight back. Get down off the fence and lend a hand, grab a-hold, be a citizen - not a subject.”
