“We are the change we have been waiting for.”

“This pleased Onyango, for to him knowledge was the source of all the white man's power, and he wanted to make sure that his son was as educated as any white man.”

“Every single one of you has something you're good at. Every single one of you has something to offer. And you have a responsibility to yourself to discover what that is. That's the opportunity an education can provide.”

“I couldn’t rid myself of the sense that Roy was in danger somehow, that old demons were driving him toward an abyss, and that if only I was a better brother, my intervention would prevent his fall.”

“Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.”

“I wish the country had fewer lawyers and more engineers.”

“All of us - we should do everything we can to make sure this country lives up to our children's expectations.”

“Our Founding Fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience’s sake.”

“We are a people of improbable hope.”

“This election is about the past vs. the future. It's about whether we settle for the same divisions and distractions and drama that passes for politics today or whether we reach for a politics of common sense and innovation, a politics of shared sacrifice and shared prosperity. There are those who will continue to tell us that we can't do this, that we can't have what we're looking for, that we can't have what we want, that we're peddling false hopes. But here is what I know. I know that when people say we can't overcome all the big money and influence in Washington, I think of that elderly woman who sent me a contribution the other day, an envelope that had a money order for $3.01 along with a verse of scripture tucked inside the envelope. So don't tell us change isn't possible. That woman knows change is possible. When I hear the cynical talk that blacks and whites and Latinos can't join together and work together, I'm reminded of the Latino brothers and sisters I organized with and stood with and fought with side by side for jobs and justice on the streets of Chicago. So don't tell us change can't happen. When I hear that we'll never overcome the racial divide in our politics, I think about that Republican woman who used to work for Strom Thurmond, who is now devoted to educating inner city-children and who went out into the streets of South Carolina and knocked on doors for this campaign. Don't tell me we can't change. Yes, we can. Yes, we can change. Yes, we can. Yes, we can heal this nation. Yes, we can seize our future. And as we leave this great state with a new wind at our backs and we take this journey across this great country, a country we love, with the message we carry from the plains of Iowa to the hills of New Hampshire, from the Nevada desert to the South Carolina coast, the same message we had when we were up and when we were down, that out of many, we are one; that while we breathe, we will hope. And where we are met with cynicism and doubt and fear and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of the American people in three simple words -- yes, we can.”

“But we do not have to think that human nature is perfect for us to still believe that the human condition can be perfected. We do not have to live in an idealized world to still reach for those ideals that will make it a better place. The non-violence practiced by men like Gandhi and King may not have been practical or possible in every circumstance, but the love that they preached - their faith in human progress - must always be the North Star that guides us on our journey. For if we lose that faith - if we dismiss it as silly or naïve; if we divorce it from the decisions that we make on issues of war and peace - then we lose what is best about humanity. We lose our sense of possibility. We lose our moral compass.”

“Scientists and engineers ought to stand side by side with athletes and entertainers as role models.”

“To the furniture worker's child in North Carolina who wants to become a doctor or a scientist, an engineer or an entrepreneur, a diplomat or even a president -- that's the future we hope for. That's the vision we share. That's where we need to go -- forward”

“There's no magic to the phrase radical Islam. It's a political talking point. It's not a strategy. And the reason I am careful about how I describe this threat has nothing to do with political correctness and everything to do with actually defeating extremism. Groups like ISIL and al-Qaeda want to make this war a war between Islam and America or between Islam and the west. They want to claim that they are the true leaders of over a billion Muslims around the world who reject their crazy notions. They want us to validate them by implying that they speak for those billion plus people. That they speak for Islam. That's their propaganda. That's how they recruit. And if we fall into the trap of painting all Muslims with a broad brush and imply that we are at war with an entire religion, then we are doing the terrorist's work for them.”

“If the people cannot trust their government to do the job for which it exists – to protect them and to promote their common welfare – all else is lost.”
