“A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a member of the natural community, a wanderer who visits but does not remain and whose travels leave only trails.”

As quoted in Reader's Digest (July 1972)

1910s, Nobel lecture (1910)
Context: In new and wild communities where there is violence, an honest man must protect himself; and until other means of securing his safety are devised, it is both foolish and wicked to persuade him to surrender his arms while the men who are dangerous to the community retain theirs. He should not renounce the right to protect himself by his own efforts until the community is so organized that it can effectively relieve the individual of the duty of putting down violence. So it is with nations. Each nation must keep well prepared to defend itself until the establishment of some form of international police power, competent and willing to prevent violence as between nations. As things are now, such power to command peace throughout the world could best be assured by some combination between those great nations which sincerely desire peace and have no thought themselves of committing aggressions. The combination might at first be only to secure peace within certain definite limits and on certain definite conditions; but the ruler or statesman who should bring about such a combination would have earned his place in history for all time and his title to the gratitude of all mankind.

The Ethics of Belief (1877), The Weight Of Authority
Context: It is hardly in human nature that a man should quite accurately gauge the limits of his own insight; but it is the duty of those who profit by his work to consider carefully where he may have been carried beyond it. If we must needs embalm his possible errors along with his solid achievements, and use his authority as an excuse for believing what he cannot have known, we make of his goodness an occasion to sin.

1960s, Inaugural address (1965)
Context: Liberty was the second article of our covenant. It was self-government. It was our Bill of Rights. But it was more. America would be a place where each man could be proud to be himself: stretching his talents, rejoicing in his work, important in the life of his neighbors and his nation. This has become more difficult in a world where change and growth seem to tower beyond the control and even the judgment of men. We must work to provide the knowledge and the surroundings which can enlarge the possibilities of every citizen. The American covenant called on us to help show the way for the liberation of man. And that is today our goal. Thus, if as a nation there is much outside our control, as a people no stranger is outside our hope.
