“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.”

“In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope?”

“Maybe the critics are right. Maybe there's no escaping our great political divide, an endless clash of armies, and any attempts to alter the rules of engagement are futile. Or maybe the trivialization of politics has reached a point of no return, so that most people see it as just one more diversion, a sport, with politicians our paunch-bellied gladiators and those who bother to pay attention just fans on the sidelines: We paint our faces red or blue and cheer our side and boo their side, and if it takes a late hit or cheap shot to beat the other team, so be it, for winning is all that matters. But I don't think so. They are out there, I think to myself, those ordinary citizens who have grown up in the midst of all the political and cultural battles, but who have found a way-in their own lives, at least- to make peace with their neighbors, and themselves. ...I imagine they are waiting for a politics with the maturity to balance idealism and realism, to distinguish between what can and cannot be compromised, to admit the possibility that the other side might sometimes have a point. They don't always understand the arguments between right and left, conservative and liberal, but they recognize the difference between dogma and common sense, responsibility and irresponsibility, between those things that last and those that are fleeting. They are out there, waiting for Republicans and Democrats to catch up with them.”

“If poverty is a disease that infects an entire community in the form of unemployment and violence, failing schools and broken homes, then we can't just treat those symptoms in isolation. We have to heal that entire community. And we have to focus on what actually works”

“No, what's troubling is the gap between the magnitude of our challenges and the smallness of our politics--the ease with which we are distracted by the petty and trivial, our chronic avoidance of tough decisions, our seeming inability to build a working concensus to tackle any big problem.”

“Hope is what led a band of colonists to rise up against an empire; what led the greatest of generations to free a continent and heal a nation; what led young women and young men to sit at lunch counters and brave fire hoses and march through Selma and Montgomery for freedom's cause. Hope is what led me here today -- with a father from Kenya, a mother from Kansas; and a story that could only happen in the United States of America. Hope is the bedrock of this nation; the belief that our destiny will not be written for us, but by us; by all those men and women who are not content to settle for the world as it is; who have courage to remake the world as it should be.

“We are the change we have been waiting for.”

“anger's a requirement for the job. The only reason anybody decides to become and organiser. Well adjusted people find more relaxing work”

“But we do not have to think that human nature is perfect for us to still believe that the human condition can be perfected. We do not have to live in an idealized world to still reach for those ideals that will make it a better place. The non-violence practiced by men like Gandhi and King may not have been practical or possible in every circumstance, but the love that they preached - their faith in human progress - must always be the North Star that guides us on our journey. For if we lose that faith - if we dismiss it as silly or naïve; if we divorce it from the decisions that we make on issues of war and peace - then we lose what is best about humanity. We lose our sense of possibility. We lose our moral compass.”

“We will not apologize for oour way of life, nor will we waver in its defense, and for those who seek to advance their aims by inducing terror and slaughtering innocents, we say to you now that our spirit is stronger and cannot be broken; you cannot outlast us, and we will defeat you.”

“Setiap strategi untuk mengurangi kemiskinan antargenerasi harus dipusatkan pada pekerjaan, bukan pada kesejahteraan--bukan hanya karena pekerjaan itu memberikan kebebasan dan pendapatan, melainkan juga karena pekerjaan itu mendatangkan kedisiplinan, struktur, harga diri, dan kesempatan untuk berkembang dalam kehidupan masyarakat.”

“By dint of vision, and determination, and most of all faith in the redeeming power of love, he endured the humiliation of arrest, the loneliness of a prison cell, the constant threats to his life, until he finally inspired a nation to transform itself, and begin to live up to the meaning of its creed.”

“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.”

“And so the moment we persuade a child, any child, to cross that threshold into a library, we've changed their lives forever, and for the better. This is an enormous force for good.”

“That’s probably what had drawn me to Regina, the way she made me feel like I didn’t have to lie.”
