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.

I realized that Eastern thought had somewhat more compassion for all living things. Man was a form of life that in another reincarnation might possibly be a horsefly or a bird of paradise or a deer. So a man of such a faith, looking at animals, might be looking at old friends or ancestors. In the East the wilderness has no evil connotation; it is thought of as an expression of the unity and harmony of the universe.

Restriction of free thought and free speech is the most dangerous of all subversions. It is the one un-American act that could most easily defeat us.

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.

One who comes to the Court must come to adore, not to protest. That's the new gloss on the First Amendment.

Thus if the First Amendment means anything in this field, it must allow protests even against the moral code that the standard of the day sets for the community. In other words, literature should not be suppressed merely because it offends the moral code of the censor.

Hiking a ridge, a meadow, a river bottom, is as healthy a form of exercise as one can get.
