“Ideas, like men, can become dictators. We Americans have so far escaped regimentation by our rulers, but have we escaped regimentation by our own ideas? I doubt if there exists today a more complete regimentation of the human mind than that accomplished by our self-imposed doctrine of ruthless utilitarianism.”
"The Farmer as a Conservationist" [1939]; Published in The River of the Mother of God and Other Essays by Aldo Leopold, Susan L. Flader and J. Baird Callicott (eds.) 1991, p. 259.

Context: As long as some of us choose to rely on nuclear weapons, we continue to risk that these same weapons will become increasingly attractive to others.
I have no doubt that, if we hope to escape self-destruction, then nuclear weapons should have no place in our collective conscience, and no role in our security.
To that end, we must ensure — absolutely — that no more countries acquire these deadly weapons.
We must see to it that nuclear-weapon states take concrete steps towards nuclear disarmament.
And we must put in place a security system that does not rely on nuclear deterrence.

Letter to George Washington (November 1779)

Address to the Annual Dinner for White House Correspondents' Association, Washington, D.C. (15 March 1941). A similar (but misleading 'quote') is inscribed on the FDR memorial, in Washington D. C., which says "They (who) seek to establish systems of government based on the regimentation of all human beings by a handful of individual rulers... Call this a New Order. It is not new and it is not order".
