“This world is like a big classroom, and USA is the teacher, while other countries are the students, as one student tries to mess with the teacher, or does something really bad. The teacher shall teach him a nice lesson. Use your brain before you try to mess with the odds.”

“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.”

“Democracy demands that the religiously motivated translate their concerns in to universal, rather than religion-specific, values... it requires that their proposals be subject to argument and amenable to reason. Now I may be opposed to abortion for religious reasons, to take one example, but if I seek to pass a law banning the practice, I cannot simply point to the teachings of my church or evoke God's will. I have to explain why abortion violates some principle that is accessible to people of all faiths, including those with no faith at all.”

“That’s probably what had drawn me to Regina, the way she made me feel like I didn’t have to lie.”

“We cannot know for certain how long we have here. We cannot foresee the trials or misfortunes that will test us along the way. We cannot know God's plan for us. What we can do is to live out our lives as best we can with purpose, and love, and joy. We can use each day to show those who are closest to us how much we care about them, and treat others with the kindness and respect that we wish for ourselves. We can learn from our mistakes and grow from our failures. And we can strive at all costs to make a better world, so that someday, if we are blessed with the chance to look back on our time here, we can know that we spent it well; that we made a difference; that our fleeting presence had a lasting impact on the lives of other human beings. ”

“We talk to these folks because they potentially have the best answers, so I know whose ass to kick.”

“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.”

“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...”

“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.”

“We now live in a world where the most valuable skill you can sell is knowledge.”

“There are a whole lot of religious people in America, including the majority of Democrats. When we abandon the field of religious discourse—when we ignore the debate about what it means to be a good Christian or Muslim or Jew; when we discuss religion only in the negative sense of where or how it should not be practiced, rather than in the positive sense of what it tells us about our obligations toward one another; when we shy away from religious venues and religious broadcasts because we assume that we will be unwelcome—others will fill the vacuum. And those who do are likely to be those with the most insular views of faith, or who cynically use religion to justify partisan ends.”

“Don't let your failures define you.”

“They spend half they lives worrying about what white folks think.”

“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.”

“This is the moment we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.”
