“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.”

“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.”

“For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. So let us mark this day with remebrance, of who we are and how far we have traveled.”

“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.”

“I had nothing to escape from except my own inner doubt.”

“In my daughters I see her every day, her joy, her capacity for wonder. I won’t try to describe how deeply I mourn her passing still. I know that she was the kindest, most generous spirit I have ever known, and that what is best in me I owe to her.”

“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.”

“Each path to knowledge involves different rules and these rules are not interchangeable.”

“We may come from different places and have different stories, but we share common hopes, and one very American dream.”

“At a time when our discourse has become so sharply polarized, at a time when we are far too eager to lay the blame for all that ails the world at the feet of those who think differently than we do, it’s important for us to pause for a moment and make sure that we are talking with each other in a way that heals, not a way that wounds.”

“I think perhaps education doesn’t do us much good unless it is mixed with sweat.”

“You might be locked in a world not of your own making, her eyes said, but you still have a claim on how it is shaped. You still have responsibilities.”

“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.”

“We hang on to our values, even if they seem at times tarnished and worn; even if, as a nation and in our own lives, we have betrayed them more often that we care to remember. What else is there to guide us? Those values are our inheritance, what makes us who we are as a people. And although we recognize that they are subject to challenge, can be poked and prodded and debunked and turned inside out bu intellectuals and cultural critics, they have proven to be both surprisingly durable and surprisingly constant across classes, and races, and faiths, and generations. We can make claims on their behalf, so long as we understand that our values must be tested against fact and experience, so long as we recall that they demand deeds and not just words.”

“If Latinos sit out the election instead of saying, ‘We’re gonna punish our enemies and we’re gonna reward our friends who stand with us on issues that are important to us,’ if they don’t see that kind of upsurge in voting in this election, then I think it’s gonna be harder and that’s why I think it’s so important that people focus on voting on November 2.”
