John F. Kennedy
(29 May 1917 - 22 Nov 1963)

American president who was 35th President of the U.S. (1961-63). During his term, he had to deal with the situation of Russian offensive nuclear weapons in Cuba, discovered in Oct 1962. By 1963, a test ban treaty was established to slow the arms race. He was assassinated later that year.

Science Quotes by John F. Kennedy (14 quotes)

A Canadian newspaperman said yesterday that this is the President's 'Easter egghead roll on the White House lawn.' I want to deny that!

Don't ever take a fence down until you know the reason why it was put up.
— John F. Kennedy
In a personal notebook (1945-46). Discussed in Hugh Rawson and Margaret Miner, The Oxford Dictionary of American Quotations (2005), 201, as possibly being a very brief paraphrase of a verse by Robert Frost from 'The Wall' (1914) (See Robert Frost quotations page on this site). Elsewhere, it has been suggested to be a summary paraphrase of a much longer passage in G.K. Chesterton, The Thing (1929). (See G.K. Chesterton quotations on this site.) Meanwhile, many collections of quotations incorrectly attribute the short quote as worded above directly to either Robert Frost or G.K. Chesterton.

In the years since man unlocked the power stored up within the atom, the world has made progress, halting, but effective, toward bringing that power under human control. The challenge may be our salvation. As we begin to master the destructive potentialities of modern science, we move toward a new era in which science can fulfill its creative promise and help bring into existence the happiest society the world has ever known.

Science And Society

The language of science is universal, and perhaps scientists have been the most international of all professions in their outlook... Every time you scientists make a major invention, we politicians have to invent a new institution to cope with it—and almost invariably, these days, it must be an international institution.
— John F. Kennedy

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 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 preeminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war.

Quotes by others about John F. Kennedy (1)

Scientists constantly get clobbered with the idea that we spent 27 billion dollars on the Apollo programs, and are asked “What more do you want?” We didn't spend it; it was done for political reasons. ... Apollo was a response to the Bay of Pigs fiasco and to the successful orbital flight of Yuri Gagarin. President Kennedy's objective was not to find out the origin of the moon by the end of the decade; rather it was to put a man on the moon and bring him back, and we did that.
— Carl Sagan
Quoted by Dennis Meredith, in 'Carl Sagan's Cosmic Connection and Extraterrestrial Life-Wish', Science Digest (Jun 1979), 85, 38 & 89. Reproduced in Carl Sagan and Tom Head, Conversations With Sagan (2006), 55-56.

Carl Sagan Thumbnail At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. -- Carl Sagan
