“We must talk and reach for common understandings, precisely because all of us are imperfect and can never act with the certainty that God is on our side; and yet at times we must act nonetheless, as if we are certain, protected from error only by providence.”

“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.”

“Where once I’d felt the need to live up to his expectations, I now felt as if I had to make up for all his mistakes.”

“Hope -- Hope in the face of difficulty. Hope in the face of uncertainty. The audacity of hope! In the end, that is God’s greatest gift to us...A belief in things not seen. A belief that there are better days ahead.”

“What Washington Needs is Adult Supervision.”

“Rather than subsidize the past, we should invest in the future.”

“Tonight, I say to the American people, to Democrats and Republicans and Independents across this great land: enough! This moment, this election is our chance to keep, in the 21st century, the American promise alive. Because next week, in Minnesota, the same party that brought you two terms of George Bush and Dick Cheney will ask this country for a third. And we are here because we love this country too much to let the next four years look like the last eight. On Nov. 4, we must stand up and say: "Eight is enough.”

“Eventually my rejection of authority spilled into self-indulgence and self-destructiveness, and by the time I enrolled in college, I'd begun to see how any challenge to convention harbored within it the possibility of its own excesses and its own orthodoxy. I started to reexamine my assumptions, and recalled the values my mother and grandparents had taught me. In this slow, fitful process of sorting out what I believed, I began silently registering the point in dorm-room conversations when my college friends and I stopped thinking and slipped into can't: the point at which the denunciations of capitalism or American imperialism came too easily, and the freedom from the constraints of monogamy or religion was proclaimed without fully understanding the value of such constraints, and the role of victim was too readily embraced as a means of shedding responsibility, or asserting entitlement, or claiming moral superiority over those not so victimized.”

“As president, I believe that robotics can inspire young people to pursue science and engineering. And I also want to keep an eye on those robots in case they try anything.”

“it doesn't matter who you are or where you come from or what you look like or where you love. It doesn't matter whether you're black or white or Hispanic or Asian or Native American or young or old or rich or poor, able, disabled, gay or straight!”

“Change won't come from the top, Change will come from mobilized grassroots.”

“There's a wonderful, perhaps apocryphal story that people tell about Daniel Patrick Moynihan, the brilliant, prickly, and iconoclastic late senator from New York. Apparently, Moynihan was in a heated argument with one of his colleagues over an issue, and the other senator, sensing he was on the losing side of the argument, blurted out: 'Well, you may disagree with me, Pat, I'm entitled to my own opinion." To which Moynihan frostily replied, "You are entitled to you own opinion, but you are not entitled to you own facts.”

“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.”

“the big house and the nice suits and the other things that our money culture says you should buy ... betrays a poverty of ambition.”

“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.”
