"In this tree of humanity, with all of our branches and diversity, we all go back to the same root.  We’re all one family -- we're all one tribe. And yet so much of the suffering in our world stems from our failure to remember that -- to not recognize ourselves in each other. We think because somebody’s skin is slightly different, or their hair is slightly different, or their religious faith is differently expressed, or they speak a different language that it justifies somehow us treating them with less dignity. And that becomes the source of so many of our problems. And we think somehow that we make ourselves better by putting other people down. And that becomes the source of so many of our problems. When we begin to see other as somehow less than ourselves -- when we succumb to these artificial divisions of faith or sect or tribe or ethnicity -- then even the most awful abuses are justified in the minds of those who are thinking in those ways. And in the end, abusers lose their own humanity, as well."

““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.”
