“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.”

“We have no authoritative figure, no Walter Cronkite or Edward R. Murrow whom we all listen to and trust to sort out contradictory claims. Instead, the media is splintered into a thousand fragments, each with its own version of reality, each claiming the loyalty of a splintered nation.”

“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.”

“in a climate of constant technological change.”

“Where once I’d felt the need to live up to his expectations, I now felt as if I had to make up for all his mistakes.”

“Focusing your life solely on making a buck shows a poverty of ambition. It asks too little of yourself. And it will leave you unfulfilled.”

“In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted, for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things -- some celebrated, but more often men and women obscure in their labor -- who have carried us up the long, rugged path towards prosperity and freedom.”

“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.”

“A healthy, dose of guilt never hurt anybody. It’s what civilization was built on, guilt. A highly underrated emotion.”

“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.”

“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”

“Words do inspire. ”

“Let us keep that promise – that American promise – and in the words of Scripture -- hold firmly, without wavering, to the hope that we confess.”

“Change has come!”

“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.”
