"Our celebration of initiative and enterprise, our insistence on hard work and personal responsibility, these are constants in our character. But we have always understood that when times change, so must we; that fidelity to our founding principles requires new responses to new challenges; that preserving our individual freedoms ultimately requires collective action. 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."

““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.”

“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.”

“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.”

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