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

“I confess to wincing every so often at a poorly chosen word, a mangled sentence, an expression of emotion that seems indulgent or overly practiced. I have the urge to cut the book by fifty pages or so, possessed as I am with a keener appreciation for brevity.”

“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.”

“Let me tell your something. I'm from Chicago. I don't break.”

“I know, I have seen, the desperation and disorder of the powerless: how it twists the lives of children on the streets of Jakarta or Nairobi in much the same way as it does the lives of children on Chicago’s South Side, how narrow the path is for them between humiliation and untrammeled fury, how easily they slip into violence and despair. I know that the response of the powerful to this disorder—alternating as it does between a dull complacency and, when the disorder spills out of its proscribed confines, a steady, unthinking application of force, of longer prison sentences and more sophisticated military hardware—is inadequate to the task. I know that the hardening of lines, the embrace of fundamentalism and tribe, dooms us all. And so what was a more interior, intimate effort on my part, to understand this struggle and to find my place in it, has converged with a broader public debate, a debate in which I am professionally engaged, one that will shape our lives and the lives of our children for many years to come.

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

“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.”

“well as programs like the GI Bill that made a college education available to millions, government”

“Change won’t come from the top, I would say. Change will come from a mobilized grass roots.

“Self-reliance and independence can transform into selfishness and license, ambition into greed and a frantic desire to succeed at any cost. More than once in our history we've seen patriotism slide into jingoism, xenophobia, the stifling of dissent; we've seen faith calcify into self-righteousness, closed-mindedness, and cruelty toward others. Even the impulse toward charity can drift into a stifling paternalism, an unwillingness to acknowledge the ability of others to do for themselves. ....In a country as diverse as ours, there will always be passionate arguments about how we draw the line when it comes to government action. That is how our democracy works. But our democracy might work better if we recognized that all of us posses values worthy of respect: if liberals at least acknowledge that the recreational hunter feels the same way about his gun as they feel about their library books, and if conservatives recognized that most women feel as protective of their right to reproductive freedom as evangelicals do of their right to worship.”

“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.”

“That's just how white folks will do you. It wasn't merely the cruelty involved; I was learning that black people could be mean and then some. It was a particular brand of arrogance, an obtuseness in otherwise sane people that brought forth our bitter laughter. It was as if whites didn't know they were being cruel in the first place. Or at least thought you deserved of their scorn.”

“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.”

“Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America.”b”

“To all those watching tonight from beyond our shores, from parliaments and palaces, to those who are huddled around radios in the forgotten corners of the world, our stories are singular, but our destiny is shared, and a new dawn of American leadership is at hand.”
