“Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends - honesty and hard work, courage and fair play, tolerance and curiosity, loyalty and patriotism - these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility - a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task.”

“It’s been a long time coming, but tonight, because of what we did on this day, in this election, at this defining moment, change has come to America.”

“We must act, knowing that our work will be imperfect.”

this was the moment when the rise of the oceans began to slow and our planet began to heal ..."~~Barack Obama upon winning the Democratic nomination for presidency conveys his thinking of what that means ....for the world, Tuesday, JUNE 03, 2008” 

“The people back home, they didn’t even know anyone else who had ridden in an airplane before. So they expected everything from him. ‘Ah, Barack, you are a big shot now. You should give me something. You should help me.’ Always these pressures from family. And he couldn’t say no, he was so generous. You”

“education available to millions, government has helped”

“I only know what I have seen. What I have not seen doesn't make my heart heavy.”

“Indeed, it's not a stretch to say that most voters no longer choose their representatives; instead, representatives choose their voters.”

“Let it be told to the future world that in the depth of winter, when nothing but hope and virtue could survive, that the city and the country, alarmed at one common danger, came forth to meet it.” 

“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.”

“You see, when a tragedy like this strikes, it is part of our nature to demand explanations - to try to impose some order on the chaos, and make sense out of that which seems senseless.”

“Progress does not compel us to settle centuries-old debates about the role of government for all time — but it does require us to act in our time,”

“When I think about how I understand my role as citizen, setting aside being president, and the most important set of understandings that I bring to that position of citizen, the most important stuff I’ve learned I think I’ve learned from novels. It has to do with empathy. It has to do with being comfortable with the notion that the world is complicated and full of grays, but there’s still truth there to be found, and that you have to strive for that and work for that. And the notion that it’s possible to connect with some[one] else even though they’re very different from you.”

“So, let us summon a new spirit of patriotism, of responsibility, where each of us resolves to pitch in and work harder and look over not only ourselves, but each other.”

“Change has come!”
