Remarks at the presentation of NASA's Distinguished Service Medal to Astronaut Alan B. Shepard (8 May 1961) http://www.presidency.ucsb.edu/ws/index.php?pid=8119 — Video of presentation at YouTube http://www.youtube.com/watch?v=M0OurosNBFo
1961
Context: Commander Shepard has pointed out from the time that this flight began and from the time this flight was a success, that this was a common effort in which a good many men were involved. I think it does credit to him that he is associated with such a distinguished group of Americans whom we are all glad to honor today, his companions in the flight into outer space, so I think we want to give them all a hand. … I also want to take cognizance of the fact that this flight was made out in the open with all the possibilities of failure, which would have been damaging to our country's prestige. Because great risks were taken in that regard, it seems to me that we have some right to claim that this open society of ours which risked much, gained much. … This is a civilian award for a great civilian accomplishment, and therefore I want to again express my congratulations to Alan Shepard. We are very proud of him, and I speak on behalf of the Vice President, who is Chairman of our Space Council and who bears great responsibilities in this field, and the Members of the House and Senate Space Committee who are with us today. [accidentally drops the medallion, and picks it up] This decoration which has gone from the ground up — here.

born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage — and unwilling to witness or permit the slow undoing of those human rights to which this Nation has always been committed, and to which we are committed today at home and around the world.

1961, Inaugural Address

where there is no Catholic vote, no anti-Catholic vote, no bloc voting of any kind — and where Catholics, Protestants and Jews, at both the lay and pastoral level, will refrain from those attitudes of disdain and division which have so often marred their works in the past, and promote instead the American ideal of brotherhood.
1960, Speech to the Greater Houston Ministerial Association

1962, Address at Independence Hall
Context: On this fourth day of July, 1962, we who are gathered at this same hall, entrusted with the fate and future of our States and Nation, declare now our vow to do our part to lift the weights from the shoulders of all, to join other men and nations in preserving both peace and freedom, and to regard any threat to the peace or freedom of one as a threat to the peace and freedom of all.

1961, Address to ANPA
Context: Without debate, without criticism, no Administration and no country can succeed — and no republic can survive. That is why the Athenian lawmaker Solon decreed it a crime for any citizen to shrink from controversy. And that is why our press was protected by the First Amendment — the only business in America specifically protected by the Constitution- -not primarily to amuse and entertain, not to emphasize the trivial and the sentimental, not to simply "give the public what it wants" — but to inform, to arouse, to reflect, to state our dangers and our opportunities, to indicate our crises and our choices, to lead, mold, educate and sometimes even anger public opinion.
This means greater coverage and analysis of international news — for it is no longer far away and foreign but close at hand and local. It means greater attention to improved understanding of the news as well as improved transmission. And it means, finally, that government at all levels, must meet its obligation to provide you with the fullest possible information outside the narrowest limits of national security — and we intend to do it.

1963, Third State of the Union Address

1961, The City upon a Hill speech
Context: During the last sixty days, I have been at the task of constructing an administration. It has been a long and deliberate process. Some have counseled greater speed. Others have counseled more expedient tests. But I have been guided by the standard John Winthrop set before his shipmates on the flagship Arbella three hundred and thirty-one years ago, as they, too, faced the task of building a new government on a perilous frontier. "We must always consider," he said, "that we shall be as a city upon a hill — the eyes of all people are upon us." Today the eyes of all people are truly upon us — and our governments, in every branch, at every level, national, state and local, must be as a city upon a hill — constructed and inhabited by men aware of their great trust and their great responsibilities. For we are setting out upon a voyage in 1961 no less hazardous than that undertaken by the Arbella in 1630. We are committing ourselves to tasks of statecraft no less awesome than that of governing the Massachusetts Bay Colony, beset as it was then by terror without and disorder within. History will not judge our endeavors — and a government cannot be selected — merely on the basis of color or creed or even party affiliation. Neither will competence and loyalty and stature, while essential to the utmost, suffice in times such as these.

1961, Inaugural Address
Context: So let us begin anew — remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear. But let us never fear to negotiate.
Let both sides explore what problems unite us instead of belaboring those problems which divide us. [... ] Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
Let both sides unite to heed in all corners of the earth the command of Isaiah — to "undo the heavy burdens … and to let the oppressed go free."

1961, Speech to Special Joint Session of Congress
Context: Finally, if we are to win the battle that is now going on around the world between freedom and tyranny, the dramatic achievements in space which occurred in recent weeks should have made clear to us all, as did the Sputnik in 1957, the impact of this adventure on the minds of men everywhere, who are attempting to make a determination of which road they should take. […] Now it is time to take longer strides — time for a great new American enterprise — time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth. I believe we possess all the resources and talents necessary. But the facts of the matter are that we have never made the national decisions or marshaled the national resources required for such leadership. We have never specified long-range goals on an urgent time schedule, or managed our resources and our time so as to insure theft fulfillment. Recognizing the head start obtained by the Soviets with their large rocket engines, which gives them many months of lead-time, and recognizing the likelihood that they will exploit this lead for some time to come in still more impressive successes, we nevertheless are required to make new efforts on our own. For while we cannot guarantee that we shall one day be first, we can guarantee that any failure to make this effort will make us last. We take an additional risk by making it in full view of the world, but as shown by feat of astronaut Shepard, this very risk enhances our stature when we are successful. But this is not merely a race. Space is open to us now; and our eagerness to share its meaning is not governed by the efforts of others. We go into space because whatever mankind must undertake, free men must fully share.

1961, Address to ANPA
Context: The very word "secrecy" is repugnant in a free and open society; and we are as a people inherently and historically opposed to secret societies, to secret oaths and to secret proceedings. We decided long ago that the dangers of excessive and unwarranted concealment of pertinent facts far outweighed the dangers which are cited to justify it. Even today, there is little value in opposing the threat of a closed society by imitating its arbitrary restrictions. Even today, there is little value in insuring the survival of our nation if our traditions do not survive with it. And there is very grave danger that an announced need for increased security will be seized upon by those anxious to expand its meaning to the very limits of official censorship and concealment. That I do not intend to permit to the extent that it is in my control. And no official of my Administration, whether his rank is high or low, civilian or military, should interpret my words here tonight as an excuse to censor the news, to stifle dissent, to cover up our mistakes or to withhold from the press and the public the facts they deserve to know.

1961, Berlin Crisis speech
Context: We will at all times be ready to talk, if talk will help. But we must also be ready to resist with force, if force is used upon us. Either alone would fail. Together, they can serve the cause of freedom and peace.

1961, Speech to Special Joint Session of Congress
Context: I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations — explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon — if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.

1961, Address to ANPA
Context: Today no war has been declared — and however fierce the struggle may be, it may never be declared in the traditional fashion. Our way of life is under attack. Those who make themselves our enemy are advancing around the globe. The survival of our friends is in danger. And yet no war has been declared, no borders have been crossed by marching troops, no missiles have been fired.
If the press is awaiting a declaration of war before it imposes the self-discipline of combat conditions, then I can only say that no war ever posed a greater threat to our security. If you are awaiting a finding of "clear and present danger," then I can only say that the danger has never been more clear and its presence has never been more imminent.
It requires a change in outlook, a change in tactics, a change in missions — by the government, by the people, by every businessman or labor leader, and by every newspaper. For we are opposed around the world by a monolithic and ruthless conspiracy that relies primarily on covert means for expanding its sphere of influence — on infiltration instead of invasion, on subversion instead of elections, on intimidation instead of free choice, on guerrillas by night instead of armies by day. It is a system which has conscripted vast human and material resources into the building of a tightly knit, highly efficient machine that combines military, diplomatic, intelligence, economic, scientific and political operations. Its preparations are concealed, not published. Its mistakes are buried, not headlined. Its dissenters are silenced not praised. No expenditure is questioned, no rumor is printed, no secret is revealed. It conducts the Cold War, in short, with a war-time discipline no democracy would ever hope or wish to match.
Nevertheless, every democracy recognizes the necessary restraints of national security — and the question remains whether those restraints need to be more strictly observed if we are to oppose this kind of attack as well as outright invasion.

1961, UN speech
Context: We meet in an hour of grief and challenge. Dag Hammarskjold is dead. But the United Nations lives. His tragedy is deep in our hearts, but the task for which he died is at the top of our agenda. A noble servant of peace is gone. But the quest for peace lies before us.
The problem is not the death of one man — the problem is the life of this organization. It will either grow to meet the challenges of our age, or it will be gone with the wind, without influence, without force, without respect. Were we to let it die, to enfeeble its vigor, to cripple its powers, we would condemn our future. For in the development of this organization rests the only true alternative to war — and war appeals no longer as a rational alternative. Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes. It can no longer concern the great powers alone. For a nuclear disaster, spread by wind and water and fear, could well engulf the great and the small, the rich and the poor, the committed and the uncommitted alike. Mankind must put an end to war — or war will put an end to mankind.
So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.

1963, American University speech
Context: Some say that it is useless to speak of world peace or world law or world disarmament — and that it will be useless until the leaders of the Soviet Union adopt a more enlightened attitude. I hope they do. I believe we can help them do it. But I also believe that we must reexamine our own attitude — as individuals and as a Nation — for our attitude is as essential as theirs. And every graduate of this school, every thoughtful citizen who despairs of war and wishes to bring peace, should begin by looking inward — by examining his own attitude toward the possibilities of peace, toward the Soviet Union, toward the course of the cold war and toward freedom and peace here at home.

acting alone, acting in groups, acting in the United Nations, for plague and pestilence, and plunder and pollution, the hazards of nature, and the hunger of children are the foes of every nation. The earth, the sea, and the air are the concern of every nation. And science, technology, and education can be the ally of every nation. Never before has man had such capacity to control his own environment, to end thirst and hunger, to conquer poverty and disease, to banish illiteracy and massive human misery. We have the power to make this the best generation of mankind in the history of the world — or to make it the last.
1963, UN speech

1961, Address at the University of Washington
Context: We increase our arms at a heavy cost, primarily to make certain that we will not have to use them. We must face up to the chance of war, if we are to maintain the peace. We must work with certain countries lacking in freedom in order to strengthen the cause of freedom. We find some who call themselves neutral who are our friends and sympathetic to us, and others who call themselves neutral who are unremittingly hostile to us. And as the most powerful defender of freedom on earth, we find ourselves unable to escape the responsibilities of freedom, and yet unable to exercise it without restraints imposed by the very freedoms we seek to protect. We cannot, as a free nation, compete with our adversaries in tactics of terror, assassination, false promises, counterfeit mobs and crises. We cannot, under the scrutiny of a free press and public, tell different stories to different audiences, foreign and domestic, friendly and hostile. We cannot abandon the slow processes of consulting with our allies to match the swift expediencies of those who merely dictate to their satellites. We can neither abandon nor control the international organization in which we now cast less than 1 percent of the vote in the General Assembly. We possess weapons of tremendous power — but they are least effective in combating the weapons most often used by freedom's foes: subversion, infiltration, guerrilla warfare, civil disorder. We send arms to other peoples — just as we send them the ideals of democracy in which we believe — but we cannot send them the will to use those arms or to abide by those ideals. And while we believe not only in the force of arms but in the force of right and reason, we have learned that reason does not always appeal to unreasonable men — that it is not always true that "a soft answer turneth away wrath" — and that right does not always make might. In short, we must face problems which do not lend themselves to easy or quick or permanent solutions. And we must face the fact that the United States is neither omnipotent or omniscient — that we are only 6 percent of the world's population — that we cannot impose our will upon the other 94 percent of mankind — that we cannot right every wrong or reverse each adversity — and that therefore there cannot be an American solution to every world problem.

1963, Speech at Amherst College
Context: If art is to nourish the roots of our culture, society must set the artist free to follow his vision wherever it takes him. We must never forget that art is not a form of propaganda; it is a form of truth. And as Mr. MacLeish once remarked of poets, there is nothing worse for our trade than to be in style. In free society art is not a weapon and it does not belong to the spheres of polemic and ideology. Artists are not engineers of the soul. It may be different elsewhere. But democratic society — in it, the highest duty of the writer, the composer, the artist is to remain true to himself and to let the chips fall where they may. In serving his vision of the truth, the artist best serves his nation. And the nation which disdains the mission of art invites the fate of Robert Frost's hired man, the fate of having "nothing to look backward to with pride, and nothing to look forward to with hope."

Commencement address, Yale University, New Haven, Connecticut (11 June 1962) http://millercenter.org/scripps/archive/speeches/detail/3370
1962
Context: The great enemy of the truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

1960, The New Frontier
Context: But I think the American people expect more from us than cries of indignation and attack. The times are too grave, the challenge too urgent, and the stakes too high — to permit the customary passions of political debate. We are not here to curse the darkness, but to light the candle that can guide us through that darkness to a safe and sane future. As Winston Churchill said on taking office some twenty years ago: if we open a quarrel between the present and the past, we shall be in danger of losing the future. Today our concern must be with that future. For the world is changing. The old era is ending. The old ways will not do. [... ] It is a time, in short, for a new generation of leadership — new men to cope with new problems and new opportunities.

1960, Speech to the Greater Houston Ministerial Association
Context: That is the kind of America in which I believe. And it represents the kind of Presidency in which I believe — a great office that must neither be humbled by making it the instrument of any one religious group nor tarnished by arbitrarily withholding its occupancy from the members of any one religious group. I believe in a President whose religious views are his own private affair, neither imposed by him upon the nation or imposed by the nation upon him as a condition to holding that office.

Address by the President at a Luncheon Given in His Honor by President Lopez Matcos (29 June 1962) http://www.presidency.ucsb.edu/ws/index.php?pid=8741&st=&st1=<!-- Online by Gerhard Peters and John T. Woolley, The American Presidency Project -->
1962
Context: While geography has made us neighbors, tradition has made us friends. Economics has made us partners. And necessity has made us allies — in a vast Alianza para el Progreso. Those whom nature has so joined together, let no man put asunder.

1963, Ich bin ein Berliner
Context: What is true of this city is true of Germany — real, lasting peace in Europe can never be assured as long as one German out of four is denied the elementary right of free men, and that is to make a free choice. In 18 years of peace and good faith, this generation of Germans has earned the right to be free, including the right to unite their families and their nation in lasting peace, with good will to all people. You live in a defended island of freedom, but your life is part of the main. So let me ask you as I close, to lift your eyes beyond the dangers of today, to the hopes of tomorrow, beyond the freedom merely of this city of Berlin, or your country of Germany, to the advance of freedom everywhere, beyond the wall to the day of peace with justice, beyond yourselves and ourselves to all mankind.

which may well be with us for decades to come — compels us to invest in our nation's future, to consider and meet our obligations to our children and the numberless generations that will follow.
"Special message to the Congress on Conservation (69)" (1 March 1962) http://www.jfklibrary.org/Research/Research-Aids/Ready-Reference/JFK-Quotations.aspx
1962

1962, Address at Independence Hall
Context: The necessity for comity between the National Government and the several States is an indelible lesson of our long history. Because our system is designed to encourage both differences and dissent, because its checks and balances are designed to preserve the rights of the individual and the locality against preeminent central authority, you and I, Governors, recognize how dependent we both are, one upon the other, for the successful operation of our unique and happy form of government. Our system and our freedom permit the legislative to be pitted against the executive, the State against the Federal Government, the city against the countryside, party against party, interest against interest, all in competition or in contention one with another. Our task — your task in the State House and my task in the White House — is to weave from all these tangled threads a fabric of law and progress. We are not permitted the luxury of irresolution. Others may confine themselves to debate, discussion, and that ultimate luxury — free advice. Our responsibility is one of decision — for to govern is to choose.

Special Message to the Congress on Education (20 February 1961) http://www.jfklink.com/speeches/jfk/publicpapers/1961/jfk46_61.html
1961
Context: Our progress as a nation can be no swifter than our progress in education. Our requirements for world leadership, our hopes for economic growth, and the demands of citizenship itself in an era such as this all require the maximum development of every young American's capacity. The human mind is our fundamental resource.

1960, The New Frontier
Context: For the harsh facts of the matter are that we stand on this frontier at a turning-point in history. We must prove all over again whether this nation — or any nation so conceived — can long endure — whether our society — with its freedom of choice, its breadth of opportunity, its range of alternatives — can compete with the single-minded advance of the Communist system. Can a nation organized and governed such as ours endure? That is the real question. Have we the nerve and the will? Can we carry through in an age where we will witness not only new breakthroughs in weapons of destruction — but also a race for mastery of the sky and the rain, the ocean and the tides, the far side of space and the inside of men's minds? Are we up to the task — are we equal to the challenge? Are we willing to match the Russian sacrifice of the present for the future — or must we sacrifice our future in order to enjoy the present? That is the question of the New Frontier. That is the choice our nation must make — a choice that lies not merely between two men or two parties, but between the public interest and private comfort — between national greatness and national decline — between the fresh air of progress and the stale, dank atmosphere of "normalcy" — between determined dedication and creeping mediocrity. All mankind waits upon our decision. A whole world looks to see what we will do. We cannot fail their trust, we cannot fail to try.

1960, The New Frontier
Context: But I tell you the New Frontier is here, whether we seek it or not. Beyond that frontier are the uncharted areas of science and space, unsolved problems of peace and war, unconquered pockets of ignorance and prejudice, unanswered questions of poverty and surplus. It would be easier to shrink back from that frontier, to look to the safe mediocrity of the past, to be lulled by good intentions and high rhetoric — and those who prefer that course should not cast their votes for me, regardless of party. But I believe the times demand new invention, innovation, imagination, decision. I am asking each of you to be pioneers on that New Frontier. My call is to the young in heart, regardless of age — to all who respond to the Scriptural call: "Be strong and of a good courage; be not afraid, neither be thou dismayed." For courage — not complacency — is our need today — leadership — not salesmanship. And the only valid test of leadership is the ability to lead, and lead vigorously.

1961, Speech to Special Joint Session of Congress
Context: Military and economic assistance has been a heavy burden on our citizens for a long time, and I recognize the strong pressures against it; but this battle is far from over, it is reaching a crucial stage, and I believe we should participate in it. We cannot merely state our opposition to totalitarian advance without paying the price of helping those now under the greatest pressure. We cannot merely state our opposition to totalitarian advance without paying the price of helping those now under the greatest pressure.

1962, Rice University speech
Context: There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again.

1963, Third State of the Union Address
Context: These are not domestic concerns alone. For upon our achievement of greater vitality and strength here at home hang our fate and future in the world: our ability to sustain and supply the security of free men and nations, our ability to command their respect for our leadership, our ability to expand our trade without threat to our balance of payments, and our ability to adjust to the changing demands of cold war competition and challenge. We shall be judged more by what we do at home than by what we preach abroad. Nothing we could do to help the developing countries would help them half as much as a booming U. S. economy. And nothing our opponents could do to encourage their own ambitions would encourage them half as much as a chronic lagging U. S. economy. These domestic tasks do not divert energy from our security — they provide the very foundation for freedom's survival and success.

First State of the Union Address (30 January 1961)
1961
Context: I have pledged myself and my colleagues in the cabinet to a continuous encouragement of initiative, responsibility and energy in serving the public interest. Let every public servant know, whether his post is high or low, that a man's rank and reputation in this Administration will be determined by the size of the job he does, and not by the size of his staff, his office or his budget. Let it be clear that this Administration recognizes the value of dissent and daring — that we greet healthy controversy as the hallmark of healthy change. Let the public service be a proud and lively career. And let every man and woman who works in any area of our national government, in any branch, at any level, be able to say with pride and with honor in future years: "I served the United States government in that hour of our nation's need." For only with complete dedication by us all to the national interest can we bring our country through the troubled years that lie ahead. Our problems are critical. The tide is unfavorable. The news will be worse before it is better. And while hoping and working for the best, we should prepare ourselves now for the worst.

1961, UN speech
Context: I come here today to look across this world of threats to a world of peace. In that search we cannot expect any final triumph — for new problems will always arise. We cannot expect that all nations will adopt like systems — for conformity is the jailor of freedom, and the enemy of growth. Nor can we expect to reach our goal by contrivance, by fiat or even by the wishes of all.
But however close we sometimes seem to that dark and final abyss, let no man of peace and freedom despair. For he does not stand alone. If we all can persevere, if we can in every land and office look beyond our own shores and ambitions, then surely the age will dawn in which the strong are just and the weak secure and the peace preserved.

1961, UN speech
Context: I do not ignore the remaining problems of traditional colonialism which still confront this body. Those problems will be solved, with patience, good will, and determination. Within the limits of our responsibility in such matters, my Country intends to be a participant and not merely an observer, in the peaceful, expeditious movement of nations from the status of colonies to the partnership of equals. That continuing tide of self-determination, which runs so strong, has our sympathy and our support. But colonialism in its harshest forms is not only the exploitation of new nations by old, of dark skins by light, or the subjugation of the poor by the rich. My Nation was once a colony, and we know what colonialism means; the exploitation and subjugation of the weak by the powerful, of the many by the few, of the governed who have given no consent to be governed, whatever their continent, their class, their color.

1963, Remarks Prepared for Delivery at the Trade Mart in Dallas
Context: It is fitting that these two symbols of Dallas progress are united in the sponsorship of this meeting, for they represent the best qualities, I am told, of leadership and learning in this city — and leadership and learning are indispensable to each other. The advancement of learning depends on community leadership for financial and political support and the products of that learning, in turn, are essential to the leadership's hopes for continued progress and prosperity. It is not a coincidence that those communities possessing the best in research and graduate facilities — from MIT to Cal Tech — tend to attract the new and growing industries. […] This link between leadership and learning is not only essential at the community level, it is even more indispensable in world affairs. Ignorance and misinformation can handicap the progress of a city or a company, but they can, if allowed to prevail in foreign policy, handicap this country's security. In a world of complex and continuing problems, in a world full of frustrations and irritations, America's leadership must be guided by the lights of learning and reason, or else those who confuse rhetoric with reality and the plausible with the possible will gain the popular ascendancy with their seemingly swift and simple solutions to every world problem.

1961, Inaugural Address
Variant: If a free society cannot help the many who are poor, it cannot save the few who are rich.
Context: To those people in the huts and villages of half the globe struggling to break the bonds of mass misery, we pledge our best efforts to help them help themselves, for whatever period is required — not because the communists may be doing it, not because we seek their votes, but because it is right. If a free society cannot help the many who are poor, it cannot save the few who are rich.

Variant: A man may die, nations may rise and fall, but an idea lives on. Ideas have endurance without death.

1963, Address at Vanderbilt University
Context: The essence of Vanderbilt is still learning, the essence of its outlook is still liberty, and liberty and learning will be and must be the touchstones of Vanderbilt University and of any free university in this country or the world. I say two touchstones, yet they are almost inseparable, inseparable if not indistinguishable, for liberty without learning is always in peril, and learning without liberty is always in vain.

Variant: Change is the law of life. And those who look only to the past or present are certain to miss the future.

1961, UN speech
Context: Mankind must put an end to war — or war will put an end to mankind.
So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.
Context: We meet in an hour of grief and challenge. Dag Hammarskjold is dead. But the United Nations lives. His tragedy is deep in our hearts, but the task for which he died is at the top of our agenda. A noble servant of peace is gone. But the quest for peace lies before us.
The problem is not the death of one man — the problem is the life of this organization. It will either grow to meet the challenges of our age, or it will be gone with the wind, without influence, without force, without respect. Were we to let it die, to enfeeble its vigor, to cripple its powers, we would condemn our future. For in the development of this organization rests the only true alternative to war — and war appeals no longer as a rational alternative. Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes. It can no longer concern the great powers alone. For a nuclear disaster, spread by wind and water and fear, could well engulf the great and the small, the rich and the poor, the committed and the uncommitted alike. Mankind must put an end to war — or war will put an end to mankind.
So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.

1961, Address to ANPA
Context: Without debate, without criticism, no Administration and no country can succeed — and no republic can survive. That is why the Athenian lawmaker Solon decreed it a crime for any citizen to shrink from controversy. And that is why our press was protected by the First Amendment — the only business in America specifically protected by the Constitution- -not primarily to amuse and entertain, not to emphasize the trivial and the sentimental, not to simply "give the public what it wants" — but to inform, to arouse, to reflect, to state our dangers and our opportunities, to indicate our crises and our choices, to lead, mold, educate and sometimes even anger public opinion.
This means greater coverage and analysis of international news — for it is no longer far away and foreign but close at hand and local. It means greater attention to improved understanding of the news as well as improved transmission. And it means, finally, that government at all levels, must meet its obligation to provide you with the fullest possible information outside the narrowest limits of national security — and we intend to do it.
