“We meet to celebrate the birthday of America. The coming of a new life always excites our interest. Although we know in the case of the individual that it has been an infinite repetition reaching back beyond our vision, that only makes it the more wonderful. But how our interest and wonder increase when we behold the miracle of the birth of a new nation. It is to pay our tribute of reverence and respect to those who participated in such a mighty event that we annually observe the fourth day of July. Whatever may have been the impression created by the news which went out from this city on that summer day in 1776, there can be no doubt as to the estimate which is now placed upon it. At the end of 150 years the four corners of the earth unite in coming to Philadelphia as to a holy shrine in grateful acknowledgement of a service so great, which a few inspired men here rendered to humanity, that it is still the preeminent support of free government throughout the world.”

2014, Address to European Youth (March 2014)

Context: In the Holy Book of Islam, Allah says:

"Thou seest not, in the creation of the All-merciful any imperfection, Return thy gaze, seest thou any fissure. Then Return thy gaze, again and again. Thy gaze, Comes back to thee dazzled, aweary."

This in effect is, the faith of all physicists; the deeper we seek, the more is our wonder excited, the more is the dazzlement for our gaze.

2014, Address to European Youth (March 2014)
Context: In the end, the success of our ideals comes down to us -- including the example of our own lives, our own societies. We know that there will always be intolerance. But instead of fearing the immigrant, we can welcome him. We can insist on policies that benefit the many, not just the few; that an age of globalization and dizzying change opens the door of opportunity to the marginalized, and not just a privileged few. Instead of targeting our gay and lesbian brothers and sisters, we can use our laws to protect their rights. Instead of defining ourselves in opposition to others, we can affirm the aspirations that we hold in common. That’s what will make America strong. That’s what will make Europe strong. That’s what makes us who we are. And just as we meet our responsibilities as individuals, we must be prepared to meet them as nations. Because we live in a world in which our ideals are going to be challenged again and again by forces that would drag us back into conflict or corruption. We can’t count on others to rise to meet those tests.

Space and the Spirit of Man (1965)

For the American people can no more meet the demands of today’s world by acting alone than American soldiers could have met the forces of fascism or communism with muskets and militias. No single person can train all the math and science teachers we’ll need to equip our children for the future, or build the roads and networks and research labs that will bring new jobs and businesses to our shores. Now, more than ever, we must do these things together, as one nation and one people.
