“The distrust of wit is the beginning of tyranny.”

“Freedom begins between the ears.”

“The automobile, which began as a transportation convenience, has become a bloody tyrant (50,000 lives a year), and it is the responsibility of the park service, as well as that of everyone else concerned with preserving both wilderness and civilization, to begin a campaign of resistance.”

“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.”

“The moral duty of the free writer is to begin his work at home: to be a critic of his own community, his own country, his own government, his own culture. The more freedom the writer possesses, the greater the moral obligation to play the role of critic.”

“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.”

“my god! i'm thinking, what incredible shit we've put up with most of our lives - the domestic routine (same old jobs, insufferable arrogance of elected officials, the crafty cheating and the slimy advertising of the businessman, the tedious wars in which we kill our buddies instead of our real enemies back home in the capital, the foul diseased and hideous cities and towns we live in, the constant petty tyranny of automatic washers and automobiles and tv machines and telephones -! ah christ!, i'm thinking, at the same time that i'm waving goodby to that hollering idiot on shore, what intolerable garbage and what utterly useless crap we bury ourselves in day by day, while patiently enduring at the same time the creeping strangulation of the clean white collar and the rich but modest four-in-hand garrote)”
