"Young people in the audience today, young people like Laura, were born in a place and a time where there is less conflict, more prosperity and more freedom than any time in human history. But that’s not because man’s darkest impulses have vanished. Even here, in Europe, we’ve seen ethnic cleansing in the Balkans that shocked the conscience. The difficulties of integration and globalization, recently amplified by the worst economic crisis of our lifetimes, strained the European project and stirred the rise of a politics that too often targets immigrants or gays or those who seem somehow different. While technology has opened up vast opportunities for trade and innovation and cultural understanding, it’s also allowed terrorists to kill on a horrifying scale. Around the world, sectarian warfare and ethnic conflicts continue to claim thousands of lives. And once again, we are confronted with the belief among some that bigger nations can bully smaller ones to get their way -- that recycled maxim that might somehow makes right. So I come here today to insist that we must never take for granted the progress that has been won here in Europe and advanced around the world, because the contest of ideas continues for your generation. And that’s what’s at stake in Ukraine today. Russia’s leadership is challenging truths that only a few weeks ago seemed self-evident -- that in the 21st century, the borders of Europe cannot be redrawn with force, that international law matters, that people and nations can make their own decisions about their future."

““In giving freedom to the slave, we assure freedom to the free.” That’s what President Lincoln once wrote. “Honorable alike in what we give, and what we preserve. We shall nobly save, or meanly lose, the last best hope of earth.” Mr. Speaker, leaders and members of both parties, distinguished guests: We gather here to commemorate a century and a half of freedom -- not simply for former slaves, but for all of us. Today, the issue of chattel slavery seems so simple, so obvious -- it is wrong in every sense. Stealing men, women, and children from their homelands. Tearing husband from wife, parent from child; stripped and sold to the highest bidder; shackled in chains and bloodied with the whip. It’s antithetical not only to our conception of human rights and dignity, but to our conception of ourselves -- a people founded on the premise that all are created equal.”

“Ramadan is a celebration of a faith known for great diversity and racial equality.”

“Above all, when your voices are heard in government, it's far more likely that your basic needs will be met. And that’s why reform must reach the daily lives of those who are hungry and those who are ill, and those who live without electricity or water.”

“In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope? I'm not talking about blind optimism here... No, I'm talking about something more substantial. It's the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker's son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too. Hope in the face of difficulty, hope in the face of uncertainty, the audacity of hope: In the end, that is God's greatest gift to us, the bedrock of this nation, a belief in things not seen, a belief that there are better days ahead.”

“Every nation struggles to define citizenship. America has had great debates about these issues, and those debates continue to this day, because we’re a nation of immigrants -- people coming from every different part of the world. But what we’ve learned in the United States is that there are certain principles that are universal, apply to everybody no matter what you look like, no matter where you come from, no matter what religion you practice. The right of people to live without the threat that their families may be harmed or their homes may be burned simply because of who they are or where they come from. Only the people of this country ultimately can define your union, can define what it means to be a citizen of this country. But I have confidence that as you do that you can draw on this diversity as a strength and not a weakness. Your country will be stronger because of many different cultures, but you have to seize that opportunity. You have to recognize that strength.”

“Citizenship demands a sense of common purpose; participation in the hard work of self-government; an obligation to serve to our communities.”
