“Our values call upon us to care about people we'll never meet.”

“Here's the truth: the Soviet Union had thousands of nuclear weapons, and Iran doesn't have a single one. But when the world was on the brink of nuclear holocaust, Kennedy talked to Khrushchev and he got those missiles out of Cuba. Why shouldn't we have the same courage and the confidence to talk to our enemies? That's what strong countries do, that's what strong presidents do, that's what I'll do when I'm president of the United States of America.”

“America, this is our moment. This is our time. Our time to turn the page on the policies of the past. Our time to bring new energy and new ideas to the challenges we face. Our time to offer a new direction for the country we love.”

“In the Catholic school, when it came time to pray, I would pretend to close my eyes, then peek around the room. Nothing happened. No angels descended.”

“But that’s part of what makes America wonderful, is we always had this nagging dissatisfaction that spurs us on. That’s how we ended up going west, that’s how we--“I’m tired of all these people back east; if I go west, there’s going to be my own land and I’m not going to have to put up with this nonsense, and I’m going to start my own thing, and I’ve got my homestead.” ...It is true, though, that that restlessness and that dissatisfaction which has helped us go to the moon and create the Internet and build the Transcontinental Railroad and build our land-grant colleges, that those things, born of dissatisfaction, we can very rapidly then take for granted and not tend to and not defend, and not understand how precious these things are.”

“We cannot help but believe that the old hatreds shall someday pass; that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself...”

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

“Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, for if we are truly created equal, then surely the love we commit to one another must be equal, as well.”

“Each path to knowledge involves different rules and these rules are not interchangeable.”

“We will restore science to its rightful place and wield technology's wonders to raise health care's quality and lower its cost.”

“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.”

“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.”

“To those leaders around the globe who seek to sow conflict, or blame their society’s ills on the West – know that your people will judge you on what you can build, not what you destroy.”

“We're up against the conventional thinking that says your ability to lead as president comes from longevity in Washington or proximity to the White House. But we know that real leadership is about candor and judgment and the ability to rally Americans from all walks of life around a common purpose, a higher purpose.”

“Aku tersandung pada salah satu rahasia yang tersimpan dengan baik tentang orang-orang kulit hitam: kebanyakan orang kulit hitam tidak tertarik dengan revolusi; kebanyakan kami merasa lelah dengan masalah ras.”
