“Progress does not compel us to settle centuries-old debates about the role of government for all time — but it does require us to act in our time,”

“Well, amigo … you can talk all you want about saving the world, but this city tends to eat away at such noble sentiments.”

“Let it be told to the future world that in the depth of winter, when nothing but hope and virtue could survive, that the city and the country, alarmed at one common danger, came forth to meet it.” 

“What makes a man is not the ability to have a child but having the courage to raise one.”

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

“On this Memorial Day, as our nation honors its unbroken line of fallen heroes -- and I see many of them in the audience here today -- our sense of patriotism is particularly strong.”

“When people at dinner parties ask me how I can possibly operate in the current political environment, with all the negative campaigning and personal attacks, I may mention Nelson Mandela, Aleksandr Solzhenitsyn, or some guy in a Chinese or Egyptian prison somewhere. In truth, being called names is not such a bad deal.”

“Where there is no experience the wise man is silent.”

“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.”

“Moreover, I believe that part of America's genius has always been its ability to absorb newcomers, to forge a national identity out of the disparate lot that arrived on our shores. In this we've been aided by a Constitution that--despite being marred by the original sin of slavery--has at its very core the ideas of equal citizenship under the laws; and an economic system that, more than any other, has offered opportunity to all comers, regardless of status or title or rank.”

“When I think about how I understand my role as citizen, setting aside being president, and the most important set of understandings that I bring to that position of citizen, the most important stuff I’ve learned I think I’ve learned from novels. It has to do with empathy. It has to do with being comfortable with the notion that the world is complicated and full of grays, but there’s still truth there to be found, and that you have to strive for that and work for that. And the notion that it’s possible to connect with some[one] else even though they’re very different from you.”

“We need to internalize this idea of excellence. Not many folks spend a lot of time trying to be excellent.”

“I thought I could start over, you see. But now I know you can never start over. Not really. You think you have control, but you are like a fly in somebody else’s web. Sometimes I think that’s why I like accounting. All day, you are only dealing with numbers. You add them, multiply them, and if you are careful, you will always have a solution. There’s a sequence there. An order. With numbers, you can have control….”

“I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting."

“in the state capital. But the years had also taken their toll. Some of it was just a function of my getting older, I suppose, for if you are paying attention,”
