If you think the United States has stood still, who built the largest shopping center in the world?

The point in history at which we stand is full of promise and danger. The world will either move forward toward unity and widely shared prosperity – or it will move apart.

I think technology really increased human ability. But technology cannot produce compassion.

The purposes of the United States should not be doubted. The Security Council resolutions will be enforced – the just demands of peace and security will be met – or action will be unavoidable. And a regime that has lost its legitimacy will also lose its power.

March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life’s path.

I believe in innovation and that the way you get innovation is you fund research and you learn the basic facts.

I feel that there are a few things in the world without cultural barriers.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die; a sustainable world. It could be great.

This young century will be liberty’s century.

The good opinion of mankind, like the lever of Archimedes, with the given fulcrum, moves the world.

Many badly needed goals, like fusion and cancer cure, would be achieved much sooner if we invested more.

Innovation can only occur where you can breathe free.

It is justice and respect that I want the world to dust off and put – without delay, and with tenderness – back on the head of the Palestinian child. It will be imperfect justice and respect because the injustice and disrespect have been so severe. But I believe we are right to try.

There are some loony people in this world!

I do not look upon these United States as a finished product. We are still in the making.

Of all the enemies of public liberty, war is perhaps the most to be dreaded, because it comprises and develops the germ of every other.

Every strike brings me closer to the next home run.

If children grew up according to early indications, we should have nothing but geniuses.

Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.

While some doubted that connecting the world was actually important, we were building. While others doubted that this would be sustainable, you were forming lasting connections. We just cared more about connecting the world than anyone else. And we still do today.

I consider myself to be as informed on American foreign policy as anyone in America.

America and Islam are not exclusive and need not be in competition. Instead, they overlap, and share common principles of justice and progress, tolerance and the dignity of all human beings.

War contains so much folly, as well as wickedness, that much is to be hoped from the progress of reason.

If time is not real, then the dividing line between this world and eternity, between suffering and bliss, between good and evil, is also an illusion.

It does not matter how slowly you go as long as you do not stop.

World belongs to humanity, not this leader, that leader or that king or prince or religious leader. World belongs to humanity.

After climbing a great hill, one only finds that there are many more hills to climb.

The most important question in the world is, ‚Why is the child crying?‘

Those 62 million girls who are not being educated around the world impact my life in Washington, D.C., in the United States of America. Because if we aren’t empowering and providing the skills and the resources to half of our population, then we’re not realizing our full potential as a society, as mankind.

If we choose, we can live in a world of comforting illusion.

While the rest of the world has been improving technology, Ghana has been improving the quality of man’s humanity to man.

There is not a liberal America and a conservative America – there is the United States of America. There is not a black America and a white America and latino America and asian America – there’s the United States of America.

The United States is not, and never will be, at war with Islam.

‚Tis love that makes the world go round, my baby.

Healthy discontent is the prelude to progress.

I’m going to try to unite all Americans.

Unlike Europe, China can’t be intimidated. Europe backs down if the United States looks at it the wrong way. But China, they’ve been there for 3,000 years and are paying no attention to the barbarians and don’t see any need to.

The United States was seriously defeated in Iraq by Iraqi nationalism – mostly by nonviolent resistance. The United States could kill the insurgents, but they couldn’t deal with half a million people demonstrating in the streets.

It’s not going to do any good to land on Mars if we’re stupid.

In order to carry a positive action we must develop here a positive vision.

We welcome the scrutiny of the world – because what you see in America is a country that has steadily worked to address our problems and make our union more perfect.

In every country except – industrial country except the United States, the government uses its massive purchasing power to negotiate drug prices. That’s one of the reasons prices are so much higher in the United States than in other countries.

Surely the wake left behind by mankind’s forward march reveals its movement just as clearly as the spray thrown up elsewhere by the prow.

The more you practice, the better you get, the more freedom you have to create.

I’ve actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don’t mean hybrid, I mean fully electric.

In America today, we are nearer a final triumph over poverty than is any other land.

For the world to be interesting, you have to be manipulating it all the time.

Like any well designed software product, Windows is designed, developed and tested as an integrated whole.

And while the law of competition may be sometimes hard for the individual, it is best for the race, because it ensures the survival of the fittest in every department.

In the United States, we can do almost anything we want. It’s not like Egypt, where you’re going to get murdered by the security forces.

Let’s not burn the universities yet. After all, the damage they do might be worse.

The most obvious characteristic of science is its application: the fact that, as a consequence of science, one has a power to do things. And the effect this power has had need hardly be mentioned. The whole industrial revolution would almost have been impossible without the development of science.

As scientists, we step on the shoulders of science, building on the work that has come before us – aiming to inspire a new generation of young scientists to continue once we are gone.

The important work of moving the world forward does not wait to be done by perfect men.

Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

The Global Fund is a central player in the progress being achieved on HIV, TB and malaria. It channels resources to help countries fight these diseases. I believe in its impact because I have seen it firsthand.

The community stagnates without the impulse of the individual. The impulse dies away without the sympathy of the community.

Conservatism discards Prescription, shrinks from Principle, disavows Progress; having rejected all respect for antiquity, it offers no redress for the present, and makes no preparation for the future.

The court generally moves in small steps rather than in one giant step.

When I’m doing a book tour in the States, I’ll wake up in the room sometimes in an anonymous chain hotel, and I don’t know where I am right away. I’ll go to the window, and it doesn’t help there either, especially if you’re in an anonymous strip and it’s the usual Victoria’s Secret, Gap, Chili’s, Applebee’s.

Leadership is absolutely vital if there are comparable countries which can affect the security of the world you live in. Between Lincoln and Roosevelt’s time, America was protected by huge oceans and, in practice, by the British navy. Today, it’s different, and the obsession of the Obama administration has been for retrenchment.
