“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.”

“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.”

“We cannot help but believe that the old hatreds shall someday pass; that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself...”

“One thing other nations can learn from Hawaii, he says, is the willingness of races to work together toward common development, something he has found whites elsewhere too often unwilling to do.

“Change has come!”

“It was Jefferson, not some liberal judge in the sixties, who called for a wall between church and state—and if we have declined to heed Jefferson’s advice to engage in a revolution every two or three generations, it’s only because the Constitution itself proved a sufficient defense against tyranny.”

“It [is] that courage that Africa most desperately needs.”

“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.

“Otherwise, though, the ambitions they had carried with them to Hawaii had slowly drained away, until regularity -- of schedules and pastimes ad the weather -- became their principal consolation.”

“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.”

“I realized that in some unspoken, still tentative way, she and I were already becoming a family.”

“But it’s just that he is basically a very honest person. That makes him uncompromising sometimes.” 

“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.”

“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.”
