“I’m not sure that I care for the idea of strangers examining my daily habits and folkways, studying my language, inspecting my costume, questioning me about my religion, classifying my artifacts, investigating my sexual rites and evaluating my chances for cultural survival. So I lived alone.”

“My loyalties will not be bound by national borders, or confined in time by one nation's history, or limited in the spiritual dimension by one language and culture. I pledge my allegiance to the damned human race, and my everlasting love to the green hills of Earth, and my intimations of glory to the singing stars, to the very end of space and time.”

“most of my wandering in the desert i've done alone. not so much from choice as from necessity - i generally prefer to go into places where no one else wants to go. i find that in contemplating the natural world my pleasure is greater if there are not too many others contemplating it with me, at the same time.”

“it will be objected that a constantly increasing population makes resistance and conservation a hopeless battle. this is true. unless a way is found to stabilize the nation's population, the parks can not be saved. or anything else worth a damn. wilderness preservation, like a hundred other good causes, will be forgotten under the overwhelming pressure of a struggle for mere survival and sanity in a completely urbanized, completely industrialized, ever more crowded environment. for my own part i would rather take my chances in a thermonuclear war than live in such a world.”

“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.”

“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.”

“What I am really writing about, what I have always written about, is the idea of human freedom, human community, the real world which makes both possible, and the new technocratic industrial state which threatens the existence of all three. Life and death, that's my subject, and always has been - if the reader will look beyond the assumptions of lazy critics and actually read what I have written. Which also means, quite often, reading between the lines: I am a comic writer and the generation of laughter is my aim.”
