“A nation that can't control its energy sources can't control its future.”

“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”

“The Kennedys decided we’re going to do an airlift. We’re going to go out to Africa and we’re going to start bringing young Africans over to this country and give them scholarships to study so that they can learn what a wonderful country America is. And this young man named Barack Obama got one of those tickets and came over to this country."

“We now live in a world where the most valuable skill you can sell is knowledge.”

“Change we need”

“Here's the truth: the Soviet Union had thousands of nuclear weapons, and Iran doesn't have a single one. But when the world was on the brink of nuclear holocaust, Kennedy talked to Khrushchev and he got those missiles out of Cuba. Why shouldn't we have the same courage and the confidence to talk to our enemies? That's what strong countries do, that's what strong presidents do, that's what I'll do when I'm president of the United States of America.”

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

“Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.”

“When people at dinner parties ask me how I can possibly operate in the current political environment, with all the negative campaigning and personal attacks, I may mention Nelson Mandela, Aleksandr Solzhenitsyn, or some guy in a Chinese or Egyptian prison somewhere. In truth, being called names is not such a bad deal.”

“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 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.”

“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.”

“It is the kindness to take in a stranger when the levees break; the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter's courage to storm a stairway filled with smoke, but also a parent's willingness to nurture a child, that finally decides our fate.”

“Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America — they will be met.”

“Rather than subsidize the past, we should invest in the future.”
