“Don't let your failures define you.”

“We think of faith as a source of comfort and understanding but find our expressions of faith sowing division; we believe ourselves to be a tolerant people even as racial, religious, and cultural tensions roil the landscape. And instead of resolving these tensions or mediating these conflicts, our politics fans them, exploits them,and drives us further apart.”

“There's no magic to the phrase radical Islam. It's a political talking point. It's not a strategy. And the reason I am careful about how I describe this threat has nothing to do with political correctness and everything to do with actually defeating extremism. Groups like ISIL and al-Qaeda want to make this war a war between Islam and America or between Islam and the west. They want to claim that they are the true leaders of over a billion Muslims around the world who reject their crazy notions. They want us to validate them by implying that they speak for those billion plus people. That they speak for Islam. That's their propaganda. That's how they recruit. And if we fall into the trap of painting all Muslims with a broad brush and imply that we are at war with an entire religion, then we are doing the terrorist's work for them.”

“The worst thing that colonialism did was to cloud our view of our past.”

“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.”

“Like a tourist, I watched the range of human possibility on display, trying to trace out my future in the lives of the people I saw, looking for some opening through which I could reenter.”

“I don’t like politics much,” she said. “Why’s that?” “I don’t know. People always end up disappointed.”

“A lot of shelter dogs are mutts like me.”

“In the Catholic school, when it came time to pray, I would pretend to close my eyes, then peek around the room. Nothing happened. No angels descended.”

“But whenever I tried to pin down this idea of self-esteem, the specific qualities we hoped to inculcate, the specific means by which we might feel good about ourselves, the conversation always seemed to follow a path of infinite regress. Did you dislike yourself because of your color or because you couldn’t read and couldn’t get a job? Or perhaps it was because you were unloved as a child—only, were you unloved because you were too dark? Or too light? Or because your mother shot heroin into her veins … and why did she do that anyway? Was the sense of emptiness you felt a consequence of kinky hair or the fact that your apartment had no heat and no decent furniture? Or was it because deep down you imagined a godless universe? Maybe one couldn’t avoid such questions on the road to personal salvation. What I doubted was that all the talk about self-esteem could serve as the centerpiece of an effective black politics. It demanded too much honest self-reckoning from people; without such honesty, it easily degenerated into vague exhortation. Perhaps with more self-esteem fewer blacks would be poor, I thought to myself, but I had no doubt that poverty did nothing for our self-esteem. Better to concentrate on the things we might all agree on. Give that black man some tangible skills and a job. Teach that black child reading and arithmetic in a safe, well-funded school. With the basics taken care of, each of us could search for our own sense of self-worth.”

“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.”

“If you're walking down the right path and you're willing to keep walking, eventually you'll make progress.”

“It was like - It was like Special Olympics or something.”

“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.”
