"despite how hard sometimes the world seems to be, and all you see on television is war and conflict and poverty and violence, the truth is that if you had to choose when to be born, not knowing where or who you would be, in all of human history, now would be the time. Because the world is less violent, it is healthier, it is wealthier, it is more tolerant and it offers more opportunity than any time in human history for more people than any time in human history. Now, that doesn’t mean that there aren’t still terrible things happening around the world or in this region. We still have things like human trafficking. And we still have terrible abuse of children. And there are conflicts. And so these are things that we’re going to have to tackle and deal with. But you should know that with each successive generation things have improved just a little bit. And over time, that little bit adds to a lot. And it’s now up to you, the next generation, to make sure that 20 years from now, or 30 years from now, people look back and say, wow, things are a lot better now than they were back then. And there will still be problems 20 or 30 years from now also. But they will be different problems, because you will have solved many of the problems that exist today."

““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.”

“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.”

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

“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.”
