“We will restore science to its rightful place and wield technology's wonders to raise health care's quality and lower its cost.”

“This world is like a big classroom, and USA is the teacher, while other countries are the students, as one student tries to mess with the teacher, or does something really bad. The teacher shall teach him a nice lesson. Use your brain before you try to mess with the odds.”

“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.”

“In fact, you couldn't even be sure that everything you had assumed to be an expression of your black, unfettered self-- the humor, the song, the behind-the-back pass-- had been freely chosen by you. At best, these things were a refuge; at worst, a trap. Following this maddening logic, the only thing you could choose as your own was withdrawal into a smaller and smaller coil of rage, until being black meant only the knowledge of your own powerlessness, of your own defeat. And the final irony: Should you refuse this defeat and lash out at your captors, they would have a name for that, too, a name that could cage you just as good. Paranoid. Militant. Violent. Nigger.”

“Religious freedom doesn't mean you can force others to live by your own beliefs.”

“A woman named Helen Keller fought her way through long, silent darkness. Though she could not see or hear; she taught us to look at and listen to each other. Never waiting for life to get easier, she gave others courage to face their challenges.”

“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.”

“My heart is filled with love for this country.”

“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.”

“Power. The word fixed in my mother’s mind like a curse. In America, it had generally remained hidden from view until you dug beneath the surface of things; until you visited an Indian reservation or spoke to a black person whose trust you had earned. But here power was undisguised, indiscriminate, naked, always fresh in the memory.”

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

“Moreover, I believe that part of America's genius has always been its ability to absorb newcomers, to forge a national identity out of the disparate lot that arrived on our shores. In this we've been aided by a Constitution that--despite being marred by the original sin of slavery--has at its very core the ideas of equal citizenship under the laws; and an economic system that, more than any other, has offered opportunity to all comers, regardless of status or title or rank.”

“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.”

“What makes a man is not the ability to have a child but having the courage to raise one.”

“We may not be able to stop evil in the world, but how we treat one another is entirely up to us.”
