“Those who have no sense of posterity or any concern for future generations are the ones who are really dead. I mean, they are dead right now. Walking zombies.”

“There are some good things to be said about walking. Not many, but some. Walking takes longer, for example, than any other known form of locomotion except crawling. Thus it stretches time and prolongs life. Life is already too short to waste on speed. I have a friend who's always in a hurry; he never gets anywhere. Walking makes the world much bigger and thus more interesting. You have time to observe the details. The utopian technologists foresee a future for us in which distance is annihilated. … To be everywhere at once is to be nowhere forever, if you ask me.”

“Whenever I see a photograph of some sportsman grinning over his kill, I am always impressed by the striking moral and esthetic superiority of the dead animal to the live one.”

“Simply because humankind have the power now to meddle or 'manage' or 'exercise stewardship' in every nook and cranny of the world does not mean that we have a right to do so. Even less, the obligation.”

“But of the seven deadly sins, wrath is the healthiest - next only to lust.”

“I think it is far more important to save one square mile of wilderness, anywhere, by any means, than to produce another book on the subject.”

“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.”
