Hiking a ridge, a meadow, or a river bottom, is as healthy a form of exercise as one can get. Hiking seems to put all the body cells back into rhythm. Ten to twenty miles on a trail puts one to bed with his cares unraveled.

Discovery is adventure. There is an eagerness, touched at times with tenseness, as man moves ahead into the unknown. Walking the wilderness is indeed like living. The horizon drops away, bringing new sights, sounds, and smells from the earth. When one moves through the forests, his sense of discovery is quickened. Man is back in the environment from which he emerged to build factories, churches, and schools. He is primitive again, matching his wits against the earth and sky. He is free of the restraints of society and free of its safeguards too.

Since when have we Americans been expected to bow submissively to authority and speak with awe and reverence to those who represent us?

The day should come when all of the forms of life... will stand before the court - the pileated woodpecker as well as the coyote and bear, the lemmings as well as the trout in the streams.

The Constitution and the Bill of Rights we designed to get the government off the backs of the people -- all the people. Those great documents guarantee to us all the rights to personal and spiritual self-fulfillment. But that guarantee is not self-executing. As nightfall does not come all at once, neither does oppression. In both instances, there is a twilight when everything remains seemingly unchanged. And it is in such a twilight that we all must be most aware of the change in the air -- however slight -- lest we become unwitting victims of the darkness.

A function of free speech under our system of government is to invite dispute. It may indeed best serve its high purpose when it invites a condition of unrest, creates dissatisfaction with conditions as they are, or even stirs people to anger. Speech is often provocative and challenging. It may strike at prejudices and preconceptions and have profound unsettling effects as it passes for acceptance of an idea.

The Arctic has a call that is compelling. The distant mountains [of the Brooks Range in Alaska] make one want to go on and on over the next ridge and over the one beyond. The call is that of a wilderness known only to a few...This last American wilderness must remain sacrosanct.
