Our remnants of wilderness will yield bigger values to the nation's character and health than they will to its pocketbook, and to destroy them will be to admit that the latter are the only values that interest us.

Teach the student to see the land, understand what he sees, and enjoy what he understands.

Recreational development is a job not of building roads into lovely country, but of building receptivity into the still unlovely human mind.

Patriotism requires less and less of making the eagle scream, but more and more of making him think.

Mechanized recreation already has seized nine-tenths of the woods and mountains; a decent respect for minorities should dedicate the other tenth to wilderness.

One of the penalties of an ecological education is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen.
