“What is, however, expected of intellect is that it should show a most proper way to achieve its end, be it the hunting of a beast, inventing of an instrument, laying down the foundations of a new system of economy, setting up a new form or government, kindling a war, or making peace. All these activities of man depend upon his intellectual ability. Emotions creeping in will only spoil them.”

Address to the Senate (22 January 1917)
1910s
Context: The question upon which the whole future peace and policy of the world depends is this: Is the present war a struggle for a just and secure peace, or only for a new balance of power? If it be only a struggle for a new balance of power, who will guarantee, who can guarantee, the stable equilibrium of the new arrangement? Only a tranquil Europe can be a stable Europe. There must be, not a balance of power, but a community of power; not organized rivalries, but an organized common peace.

Context: The plain fact is that men's minds are built, as has been often said, in water-tight compartments. Religious after a fashion, they yet have many other things in them beside their religion, and unholy entanglements and associations inevitably obtain. The basenesses so commonly charged to religion's account are thus, almost all of them, not chargeable at all to religion proper, but rather to religion's wicked practical partner, the spirit of corporate dominion. And the bigotries are most of them in their turn chargeable to religion's wicked intellectual partner, the spirit of dogmatic dominion, the passion for laying down the law in the form of an absolutely closed-in theoretic system. The ecclesiastical spirit in general is the sum of these two spirits of dominion.

1962, Rice University speech
Context: We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.
