I hold no preference among flowers, so long as they are wild, free, spontaneous.

I've never yet read a review of one of my own books that I couldn't have written much better myself.

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.

I know my own nation best. That's why I despise it the most. And know and love my own people, too, the swine. I'm a patriot. A dangerous man.

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.

We are befouling and destroying our own home, we are committing a slow but accelerating race suicide and life murder - planetary biocide. Now there is a mighty theme for a mighty book but a challenge to which no modern novelist or poet has yet responded. Where is our Melville, our Milton, our Thomas Mann when we need him most?

Congress is always willing to appropriate money for more and bigger paved roads, anywhere -- particularly if they form loops.
