“In world history we have other examples of frightful destruction. There was Alexander the Great and all of the destruction he caused. Napoleon, too, would have destroyed all of Europe. But unfortunately, the Nazi government, the government of which I unfortunately partook, had no Talleyrand, but we had a Ribbentrop. Through Talleyrand's policy France was saved from a catastrophe that Ribbentrop would have brought about.”

Published as having been made in an (August 1936) interview http://www.greatwar.nl/frames/default-churchill.html with William Griffin, editor of the New York Enquirer http://en.wikipedia.org/wiki/National_Enquirer, who was indicted for sedition http://www.time.com/time/magazine/printout/0,8816,773366,00.html by F.D.R.'s http://www.whitehouse.gov/history/presidents/fr32.html Attorney General Francis Biddle http://www.usdoj.gov/osg/aboutosg/biddlebio.htm in 1942. In a sworn statement before Congress in 1939 Griffin affirmed Churchill had said this; Congressional Record (1939-10-21), vol. 84, p. 686. In 1942, Churchill admitted having had the 1936 interview but disavowed having made the statement (The New York Times, 1942-10-22, p. 13).
In his article "The Hidden Tyranny," Benjamin Freedman attributed this quotation to an article in the isolationist http://www.time.com/time/magazine/article/0,9171,795133,00.html publication Scribner's Commentator in 1936. However, that magazine did not exist until 1939. He may have gotten the date wrong or might have been referring to one of its predecessors, Scribner's Monthly http://cdl.library.cornell.edu/moa/browse.journals/scmo.html or Payson Publishing's The Commentator http://www.time.com/time/magazine/article/0,9171,765655,00.html.

Harvard University address (1978)
Context: Even if we are spared destruction by war, our lives will have to change if we want to save life from self-destruction. We cannot avoid revising the fundamental definitions of human life and human society. Is it true that man is above everything? Is there no Superior Spirit above him? Is it right that man's life and society's activities have to be determined by material expansion in the first place? Is it permissible to promote such expansion to the detriment of our spiritual integrity?
If the world has not come to its end, it has approached a major turn in history, equal in importance to the turn from the Middle Ages to the Renaissance. It will exact from us a spiritual upsurge, we shall have to rise to a new height of vision, to a new level of life where our physical nature will not be cursed as in the Middle Ages, but, even more importantly, our spiritual being will not be trampled upon as in the Modern era.
This ascension will be similar to climbing onto the next anthropologic stage. No one on earth has any other way left but — upward.
