“There is a far higher degree of probability of success through non-warlike means than through the Communist strategy of civil war.”

Citizenship Papers (2003), The Failure of War
Context: National defense through war always involves some degree of national defeat. This paradox has been with us from the very beginning of our republic. Militarization in defense of freedom reduces the freedom of the defenders. There is a fundamental inconsistency between war and freedom.

Dieu se manifeste à nous au premier degré à travers la vie de l’univers, et au deuxième degré à travers la pensée de l’homme. La deuxième manifestation n’est pas moins sacrée que la première. La première s’appelle la Nature, la deuxième s’appelle l’Art.

My Day (1935–1962)
Context: In times past, the question usually asked by women was "How can we best help to defend our nation?" I cannot remember a time when the question on so many people's lips was "How can we prevent war?"
There is a widespread understanding among the people of this nation, and probably among the people of the world, that there is no safety except through the prevention of war. For many years war has been looked upon as almost inevitable in the solution of any question that has arisen between nations, and the nation that was strong enough to do so went about building up its defenses and its power to attack. It felt that it could count on these two things for safety. (20 December 1961)

Property (1935)
Context: If adequate motivations could be assured, a far higher degree of efficiency could be maintained in socialized industries than in industries operated for private gain.
