John F. Kennedy Quotes

In the 1950s, the average person saw science as something that solved problems. With the advent of nuclear weapons and pollution, the idealistic aura around scientific research has been replaced by cynicism.

Science has made us gods even before we are worthy of being men.

Just as the lunar landings inspired many young people to consider careers in space and related fields, the solution of the challenging instrumentation problems presented in space science can inspire young people to push beyond the current state of the art.

Science has radically changed the conditions of human life on earth. It has expanded our knowledge and our power, but not our capacity to use them with wisdom.

The end of the Cold War removed the immediate causes of whole destruction but not the threat contained in our knowledge. We must tame this knowledge with the ideals of justice, caring, and compassion summoned from our common human spiritual and moral heritage, if we are to live in peace and serenity in the twenty-first century.

It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy's edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create one world. Instead of one world, we have star wars, and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet's dead.

Atoms for peace. Man is still the greatest miracle and the greatest problem on earth.

I think war and armed conflict is always the last of all the options you have on the table. I think you try to avoid that at all costs. Sometimes it's unavoidable. That's the lesson of World War II. I think the other lesson of the last 50 or 60 years, however, is that, the stronger the U.S. military, the stronger our defense capabilities, the stronger the chances for peace are.

The president can't tell you what we got. I'll tell you what the world got. The world has a burgeoning nuclear power that didn't, as the Soviets, say "we might defend ourselves in a war."

The world has always been a dangerous place. Now it is dangerous in a different way, because the world order that we've known since the end of the Cold War has been radically transformed. All of the institutions that preserved peace and promoted global trade will be weaker - NATO, the EU, NAFTA - and US relationships with other countries will change, too.

, I'm going to reserve judgment on [Rex] Tillerson. But I'll ask him the same question I've asked the others: do you understand the historic lesson that the Iraq war was a failure, a strategic mistake, that's what Donald Trump says.

Gradually, ... the aspect of science as knowledge is being thrust into the background by the aspect of science as the power of manipulating nature. It is because science gives us the power of manipulating nature that it has more social importance than art. Science as the pursuit of truth is the equal, but not the superior, of art. Science as a technique, though it may have little intrinsic value, has a practical importance to which art cannot aspire.

It is clear that the American people are weary of war. However, Assad gassing his own people is an issue of our national security, regional stability and global security.

At every stage of understanding the universe better, the benefits to civilisation have been immeasurable. None of those big leaps were made with us knowing what was going to happen.

The trend lines in research and innovation look good for places such as India and China and less good for America as we go forward. So even if you're not enchanted by the prospect of cosmic discovery, the prospect of dying poor may be what it takes to understand the role of this adventure in the future of the natural world in which we live.

We cannot allow the defense of American lives to be held hostage by the United Nations -- which has already given Saddam Hussein a final warning, and now wants to give him another final warning. And, if he doesn't heed that, they will threaten him with yet another warning.

For some twenty years the window that opened at the end of the Cold War has been allowed to hang flapping in the wind. It is high time that the five nuclear-weapon states take seriously their commitment to negotiate toward nuclear disarmament.

We have important things to talk to the Russians about, despite their meddling in our elections. I hope they're talking about a way to eventually end this horrific humanitarian crisis in Syria, end that war. The Russians have more leverage than we do. I hope they're talking about the fact that, if Kim Jong-un's long-range missiles can reach Alaska one day, they can also reach Vladivostok.

The human race has reached a turning point. Man has opened the secrets of nature and mastered new powers. If he uses them wisely, he can reach new heights of civilization. If he uses them foolishly, they may destroy him. Man must create the moral and legal framework for the world which will insure that his new powers are used for good and not for evil.

The war in Iraq, specifically America's role of leadership in this war, is a painful invitation to ask ourselves what, if anything, we've learned from previous wars. I am revolted by the brutal killing of hundreds of thousands of innocent people during any war. And I'm saddened by the apparent inability of human beings to find less violent solutions to conflict and terrorism.

The H-bomb rather favors small nations that doesn't as yet possess it; they feel slightly more free to jostle other nations, having discovered that a country can stick its tongue out quite far these days without provoking war, so horrible are war's consequences.

As an observer, you can clearly see that Western countries are war-weary and don't want to be pulled into new conflicts. They always proclaim their will to fight for Israel in an emergency. That's good but what if that's not at all true when the time comes?

Going to war is an easy decision.

Machines taking over jobs - it's the history of civilization. Replacing farm animals, old forms of manual labor, now taking over small, menial aspects of cognition. But there's still plenty of room for creativity, for curiosity - many things that are related to passion, like art. But also, things about human communication and challenges, massive challenges that we left behind because we didn't want to take so much risk, such as space exploration, deep ocean exploration.

Any fool can start a war, and once he's done so, even the wisest of men are helpless to stop it - especially if it's a nuclear war.
