But why, some say, the moon? Why choose this as our goal? And they may well ask; why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?

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.

Every inhabitant of this planet must contemplate the day when this planet may no longer be habitable. Every man, woman and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads, capable of being cut at any moment by accident or miscalculation or by madness. The weapons of war must be abolished before they abolish us.

I am reminded of the great French Marshal Lyautey, who once asked his gardener to plant a tree. The gardener objected that the tree was slow-growing and would not reach maturity for a hundred years. The Marshal replied, “In that case, there is no time to lose, plant it this afternoon.”
— John F. Kennedy
Address at the University of California, Berkeley, California (23 March 1962), in Public Papers of the Presidents of the United States: John F. Kennedy (1962), 266.

I once heard a physicist and an editor discussing science news. The editor said, “If you told me that the world was flat, I’d put it in banner headlines.” The physicist replied, “I hope you’d also print a denial.” I cite that story … about the role of science in our society … that science is front-page news.

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.

Malthus argued a century and a half ago that man, by using up all his available resources, would forever press on the limits of subsistence, thus condemning humanity to an indefinite future of misery and poverty. We can now begin to hope and, I believe, know that Malthus was expressing not a law of nature, but merely the limitation then of scientific and social wisdom. The truth or falsity of his prediction will depend now, with the tools we have, on our own actions, now and in the years to come.

Man, in his quest for knowledge and progress, is determined and cannot be deterred. The exploration of space will go ahead, whether we join in or not, and it is one of the great adventures of all time, and no nation which expects to be the leader of other nations can expect to stay behind in this race for space.

Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, “Because it is there.” Well, space is there, and we’re going to climb it, and the moon and the planets are there, and new hopes for knowledge and peace are there. And, therefore, as we set sail we ask God’s blessing on the most hazardous and dangerous and greatest adventure on which man has ever embarked.

Science is no longer what one man says. The likes of Newton, Pascal and Einstein may live again. But the need for intense specialization has combined with the need for huge facilities to make group work imperative. Los Alamos, Brookhaven, and the Institute for Advanced Studies are symbols of the change. The world of science is no longer a world of lonely geniuses. It is a collection of communities.

Scientists alone can establish the objectives of their research, but society, in extending support to science, must take account of its own needs. As a layman, I can suggest only with diffidence what some of the major tasks might be on your scientific agenda, but … First, I would suggest the question of the conservation and development of our natural resources. In a recent speech to the General Assembly of the United Nations, I proposed a world-wide program to protect land and water, forests and wildlife, to combat exhaustion and erosion, to stop the contamination of water and air by industrial as well as nuclear pollution, and to provide for the steady renewal and expansion of the natural bases of life.

The American, by nature, is optimistic. He is experimental, an inventor and a builder who builds best when called upon to build greatly. Arouse his will to believe in himself, give him a great goal to believe in, and he will create the means to reach it.
— John F. Kennedy

The eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.

The future does not belong to those who are content with today, apathetic toward common problems and their fellow man alike, timid and fearful in the face of bold projects and new ideas. Rather, it will belong to those who can blend passion, reason and courage in a personal commitment to the great enterprises and ideals of American society.
— John F. Kennedy

Those who came before us made certain that this country rode the first waves of the industrial revolution, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it—we mean to lead it.

We all came from the sea. And it is an interesting biological fact that all of us have, in our veins the exact same percentage of salt in our blood that exists in the ocean, and, therefore, we have salt in our blood, in our sweat, in our tears.

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.

We will not act prematurely or unnecessarily risk the costs of world­wide nuclear war in which even the fruits of victory would be ashes in our mouth. But neither will we shrink from that risk at any time it must be faced.

Quotes by others about John F. Kennedy (2)

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.
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.

When the president said, “We’re going to send a man to the moon and return him safely,” the safe part sounded pretty good. But they were using hydrogen, and the only thing I knew about hydrogen was that they used it with the Hindenburg, and that didn’t work out too good.
Interview (30 Sep 2004) with Morley Safer at luncheon after official reopening of Rocket Park. As quoted in Corey Kilgannon, 'The Rocket Park Reopens, And Cronkite Reminisces', New York Times (1 Oct 2004), B6.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
