“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.”

“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.”

“There is no excuse for not trying.”

“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.

“If you have something, then everyone will want a piece of it. So you have to draw the line somewhere. If everyone is family, no one is family. Your father, he never understood this, I think.”

“And that brings me to one last point. I've got a simple message for all the dedicated and patriotic federal workers who have either worked without pay, or who have been forced off the job without pay for these last few weeks. Including most of my own staff. Thank you. Thanks for your service. Welcome back. What you do is important. It matters. You defend our country overseas, you deliver benefits to our troops who earned them when they come home, you guard our borders, you protect our civil rights, you help businesses grow and gain footholds in overseas markets. You protect the air we breathe, and the water our children drink, and you push the boundaries of science and space, and you guide hundreds of thousands of people each day through the glories of this country. Thank you. What you do is important, and don't let anybody else tell you different.”

“That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.”

“If there is anyone out there who still doubts that America is a place where all things are possible; who still wonders if the dream of our founders is alive in our time; who still questions the power of our Democracy; Tonight is your answer.”

“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."

“I believe in evolution, scientific inquiry, and global warming; I believe in free speech, whether politically correct or politically incorrect, and I am suspicious of using government to impose anybody's religious beliefs -including my own- on nonbelievers.”

“The emotions between the races could never be pure; even love was tarnished by the desire to find in the other some element that was missing in ourselves. Whether we sought out our demons or salvation, the other race would always remain just that: menacing, alien, and apart.”

“They, they, they. That was the problem with people like Joyce. They talked about the richness of their multicultural heritage and it sounded real good, until you noticed that they avoided black people. It wasn't a matter of conscious choice, necessarily, just a matter of gravitational pull, the way integration always worked, a one-way street. The minority assimilated into the dominant culture, not the other way around. Only white culture could be neutral and objective. Only white culture could be nonracial, willing to adopt the occasional exotic into its ranks. Only white culture had individuals. And we, the half-breeds and the college-degreed, take a survey of the situation and think to ourselves, Why should we get lumped in with the losers if we don't want to? We become only so grateful to lose ourselves in the crowd, America's happy, faceless marketplace; and we're never so outraged as when a cabbie drives past us or the woman in the elevator clutches her purse, not so much because we're bothered by the fact that such indignities are what less fortunate coloreds have to put up with every single day of their lives-- although that's what we tell ourselves-- but because we're wearing a Brooks Brothers suit and speak impeccable English and yet have somehow been mistaken for an ordinary nigger. Don't know who I am? I'm an individual!”

“My little girls can break my heart. They can make me cry just looking at them eating their string beans.”

“It was the call of workers who organized; women who reached for the ballot; a President who chose the moon as our new frontier; and a King who took us to the mountain top and pointed the way to the Promised Land. Yes we can!”

“Over the last fifteen months we've traveled to every corner of the United States. I've now been to fifty-seven states. I think, one left to go.”
