“Philosophy without action is the ruin of the soul. One brave deed is worth a hundred books, a thousand theories, a million words. Now as always we need heroes. And heroines! Down with the passive and the limp.”

“What we need now are heroes and heroines, about a million of them, one brave deed is worth a thousand books. Sentiment without action is the ruin of the soul.”

“I would not sacrifice a single living mesquite tree for any book ever written. One square mile of living desert is worth a hundred 'great books' - and one brave deed is worth a thousand.”

“Sentiment without action is the ruin of the soul.”

“Yes, there are plenty of heroes and heroines everywhere you look. They are not famous people. They are generally obscure and modest people doing useful work, keeping their families together and taking an active part in the health of their communities, opposing what is evil (in one way or another) and defending what is good. Heroes do not want power over others.”

“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.”

“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.”
