“Has joy any survival value in the operations of evolution? I suspect that it does; I suspect that the morose and fearful are doomed to quick extinction. Where there is no joy there can be no courage; and without courage all other virtues are useless.”

“We can have wilderness without freedom; we can have wilderness without human life at all, but we cannot have freedom without wilderness, we cannot have freedom without leagues of open space beyond the cities, where boys and girls, men and women, can live at least part of their lives under no control but their own desires and abilities, free from any and all direct administration by their fellow men.”

“In fact, I suspect that our only hope is disaster. Cruel tho' it is to say it, there has got to be a vast die-off in the human population -- likely including us and our families -- before the survivors find themselves in a world where a new and humble and 'religious' adaptation with nature is possible.Disaster is not necessary; the better world could be achieved through reason and common sense and a sense of fellowship -- but most of the present human world is dead set against us. Thus I was forced to the disagreeable resolutions (not solutions) which I attempted to sketch out in the novel 'Good News.' The title is of course deliberately ambiguous.”

“A giant thirst is a great joy when quenched in time.”

“There's another disadvantage to the use of the flashlight: like many other mechanical gadgets it tends to separate a man from the world around him. If I switch it on my eyes adapt to it and I can see only the small pool of light it makes in front of me; I am isolated. Leaving the flashlight in my pocket where it belongs, I remain a part of the environment I walk through and my vision though limited has no sharp or definite boundary.”

“the wilderness should be preserved for political reasons. We may need it someday not only as a refuge from excessive industrialism but also as a refuge from authoritarian government, from political oppression. Grand Canyon, Big Bend, Yellowstone, and the High Sierras may be required to function as bases for guerrilla warfare against tyranny...The value of wilderness, on the other hand, as a base for resistance to centralized domination is demonstrated by recent history. In Budapest and Santo Domingo, for example, popular revolts were easily and quickly crushed because an urbanized environment gives the advantage to the power with technological equipment. But in Cuba, Algeria, and Vietnam the revolutionaries, operating in mountain, desert, and jungle hinterlands with the active or tacit support of a thinly dispersed population, have been able to overcome or at least fight to a draw official establishment forces equipped with all of the terrible weapons of twentieth century militarism.”

“The fear of death follows from the fear of life. A man who lives fully is prepared to die at any time.”
