“I wonder, sometimes, whether men and women in fact are capable of learning from history--whether we progress from one stage to the next in an upward course or whether we just ride the cycles of boom and bust, war and peace, ascent and decline.”

“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.”

“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. ”

“Change has come!”

“Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America — they will be met.”

“At the moment that we persuade a child, any child, to cross that threshold, that magic threshold into a library, we change their lives forever, for the better”

“Otherwise, though, the ambitions they had carried with them to Hawaii had slowly drained away, until regularity -- of schedules and pastimes ad the weather -- became their principal consolation.”

“You see, when a tragedy like this strikes, it is part of our nature to demand explanations - to try to impose some order on the chaos, and make sense out of that which seems senseless.”

“At the moment that we persuade a child, any child, to cross that threshold, that magic threshold into a library, we change their lives forever, for the better”

“It was usually an effective tactic, another one of those tricks I had learned: (White) People were satisfied so long as you were courteous and smiled and made no sudden moves. They were more than satisfied, they were relieved — such a pleasant surprise to find a well-mannered young black man who didn’t seem angry all the time.”

“We did not come here to fear the future. We came here to shape it.”

“The people back home, they didn’t even know anyone else who had ridden in an airplane before. So they expected everything from him. ‘Ah, Barack, you are a big shot now. You should give me something. You should help me.’ Always these pressures from family. And he couldn’t say no, he was so generous. You”

“It is harder to end a war, than begin one.”

“The question we ask today is not whether our government is too big or too small, but whether it works”

“And so the moment we persuade a child, any child, to cross that threshold into a library, we've changed their lives forever, and for the better. This is an enormous force for good.”
