2015, Remarks to the People of Africa (July 2015)
Context: Every one of us is equal. Every one of us has worth. Every one of us matters. And when we respect the freedom of others -- no matter the color of their skin, or how they pray or who they are or who they love -- we are all more free. Your dignity depends on my dignity, and my dignity depends on yours. Imagine if everyone had that spirit in their hearts. Imagine if governments operated that way. Just imagine what the world could look like -- the future that we could bequeath these young people.

2011, Remarks by the President to Parliament in London, United Kingdom (May 2011)

2013, Cape Town University Address (June 2013)
Context: We always have the opportunity to choose our better history. We can always understand that most important decision -- the decision we make when we find our common humanity in one another. That’s always available to us, that choice. [... ] it can be heard in the confident voices of young people like you. It is that spirit, that innate longing for justice and equality, for freedom and solidarity -- that’s the spirit that can light the way forward. It's in you.

2016, State of the Union address (January 2016)
Context: But democracy does require basic bonds of trust between its citizens. It doesn't – it doesn't work if we think the people who disagree with us are all motivated by malice, it doesn't work if we think that our political opponents are unpatriotic or trying to weaken America. Democracy grinds to a halt without a willingness to compromise or when even basic facts are contested or when we listen only to those who agree with us. Our public life withers when only the most extreme voices get all the attention. And most of all, democracy breaks down when the average person feels their voice doesn't matter; that the system is rigged in favor of the rich or the powerful or some special interest. [... ] So, my fellow Americans, whatever you may believe, whether you prefer one party or no party, whether you supported my agenda or fought as hard as you could against it, our collective futures depends on your willingness to uphold your duties as a citizen, to vote, to speak out, to stand up for others, especially the weak, especially the vulnerable, knowing that each of us is only here because somebody somewhere stood up for us. We need every American to stay active in our public life and not just during election time so that our public life reflects the goodness and the decency that I see in the American people every single day.

2016, Remarks to the People of Cuba (March 2016)
Context: The ideals that are the starting point for every revolution -- America’s revolution, Cuba’s revolution, the liberation movements around the world -- those ideals find their truest expression, I believe, in democracy. Not because American democracy is perfect, but precisely because we’re not. And we -- like every country -- need the space that democracy gives us to change. It gives individuals the capacity to be catalysts to think in new ways, and to reimagine how our society should be, and to make them better.

2016, Memorial Service for Fallen Dallas Police Officers (July 2016)
Context: [S]o much of the tensions between police departments and minority communities that they serve is because we ask the police to do too much and we ask too little of ourselves. As a society, we choose to underinvest in decent schools. We allow poverty to fester so that entire neighborhoods offer no prospect for gainful employment. We refuse to fund drug treatment and mental health programs. We flood communities with so many guns that it is easier for a teenager to buy a Glock than get his hands on a computer or even a book and then we tell the police “you’re a social worker, you’re the parent, you’re the teacher, you’re the drug counselor.” We tell them to keep those neighborhoods in check at all costs, and do so without causing any political blowback or inconvenience. Don’t make a mistake that might disturb our own peace of mind. And then we feign surprise when, periodically, the tensions boil over. We know these things to be true. They’ve been true for a long time. [... ] And if we cannot even talk about these things -- if we cannot talk honestly and openly not just in the comfort of our own circles, but with those who look different than us or bring a different perspective, then we will never break this dangerous cycle.

2016, DNC Address (July 2016)
Context: America has changed over the years. But these values that my grandparents taught me — they haven’t gone anywhere. They’re as strong as ever, still cherished by people of every party, every race, every faith. They live on in each of us. What makes us American, what makes us patriots is what’s in here. That’s what matters. … And that’s why we can take the food and music and holidays and styles of other countries, and blend it into something uniquely our own. That’s why we can attract strivers and entrepreneurs from around the globe to build new factories and create new industries here. That’s why our military can look the way it does — every shade of humanity, forged into common service. That’s why anyone who threatens our values, whether fascists or communists or jihadists or homegrown demagogues, will always fail in the end.
That is America. That is America. Those bonds of affection; that common creed. We don’t fear the future; we shape it. We embrace it, as one people, stronger together than we are on our own.

2015, Eulogy for the Honorable Reverend Clementa Pinckney (June 2015)
Context: As a nation, out of this terrible tragedy, God has visited grace upon us, for he has allowed us to see where we’ve been blind. He has given us the chance, where we’ve been lost, to find our best selves. We may not have earned it, this grace, with our rancor and complacency, and short-sightedness and fear of each other -- but we got it all the same. He gave it to us anyway. He’s once more given us grace. But it is up to us now to make the most of it, to receive it with gratitude, and to prove ourselves worthy of this gift.

2016, Memorial Service for Fallen Dallas Police Officers (July 2016)
Context: I've seen how a spirit of unity, born of tragedy, can gradually dissipate, overtaken by the return to business as usual, by inertia and old habits and expediency. I see how easily we slip back into our old notions, because they’re comfortable, we’re used to them. I’ve seen how inadequate words can be in bringing about lasting change. I’ve seen how inadequate my own words have been. And so I’m reminded of a passage in *John’s Gospel [First John]: Let us love not with words or speech, but with actions and in truth. If we’re to sustain the unity we need to get through these difficult times, if we are to honor these five outstanding officers who we’ve lost, then we will need to act on the truths that we know. And that’s not easy. It makes us uncomfortable. But we’re going to have to be honest with each other and ourselves.

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.

2014, Review of Signals Intelligence Speech (June 2014)
Context: There was a recognition by all who participated in these reviews that the challenges to our privacy do not come from government alone. Corporations of all shapes and sizes track what you buy, store and analyze our data, and use it for commercial purposes; that’s how those targeted ads pop up on your computer and your smartphone periodically. But all of us understand that the standards for government surveillance must be higher. Given the unique power of the state, it is not enough for leaders to say: Trust us, we won’t abuse the data we collect. For history has too many examples when that trust has been breached. Our system of government is built on the premise that our liberty cannot depend on the good intentions of those in power; it depends on the law to constrain those in power.

2013, Second Inaugural Address (January 2013)
Context: The patriots of 1776 did not fight to replace the tyranny of a king with the privileges of a few or the rule of a mob.  They gave to us a republic, a government of, and by, and for the people, entrusting each generation to keep safe our founding creed. And for more than two hundred years, we have. Through blood drawn by lash and blood drawn by sword, we learned that no union founded on the principles of liberty and equality could survive half-slave and half-free. We made ourselves anew, and vowed to move forward together.
