“all the education and good intentions in the world couldn’t help plug up the holes in the universe or give you the power to change its blind, mindless course.”

ilainya meragukan namun tidak mau menggunakan uang itu untuk melindungi pabrik-pabrik kimia yang sangat rapuh di pusat-pusat urban yang utama, menjadi semakin sulit bagi kita untuk meminta negara-negara lain menjaga pabrik-pabrik tenaga nuklir mereka.”

“And that, I suppose, is what I'd been trying to tell my mother that day: that her faith in justice and rationality was misplaced, that we couldn't overcome after all, that all the education and good intentions in the world couldn't help you plug up the holes in the universe or give you the power to change its blind, mindless course.”

“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.”

“Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America.”b”

“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”

“These others, they have treated you badly. They are just too lazy to work for themselves.’ And you know what he would say to me? He would say, ‘How do you know that man does not need this small thing more than me?”

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

“It is harder to end a war, than begin one.”

“This election is about the past vs. the future. It's about whether we settle for the same divisions and distractions and drama that passes for politics today or whether we reach for a politics of common sense and innovation, a politics of shared sacrifice and shared prosperity. There are those who will continue to tell us that we can't do this, that we can't have what we're looking for, that we can't have what we want, that we're peddling false hopes. But here is what I know. I know that when people say we can't overcome all the big money and influence in Washington, I think of that elderly woman who sent me a contribution the other day, an envelope that had a money order for $3.01 along with a verse of scripture tucked inside the envelope. So don't tell us change isn't possible. That woman knows change is possible. When I hear the cynical talk that blacks and whites and Latinos can't join together and work together, I'm reminded of the Latino brothers and sisters I organized with and stood with and fought with side by side for jobs and justice on the streets of Chicago. So don't tell us change can't happen. When I hear that we'll never overcome the racial divide in our politics, I think about that Republican woman who used to work for Strom Thurmond, who is now devoted to educating inner city-children and who went out into the streets of South Carolina and knocked on doors for this campaign. Don't tell me we can't change. Yes, we can. Yes, we can change. Yes, we can. Yes, we can heal this nation. Yes, we can seize our future. And as we leave this great state with a new wind at our backs and we take this journey across this great country, a country we love, with the message we carry from the plains of Iowa to the hills of New Hampshire, from the Nevada desert to the South Carolina coast, the same message we had when we were up and when we were down, that out of many, we are one; that while we breathe, we will hope. And where we are met with cynicism and doubt and fear and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of the American people in three simple words -- yes, we can.”

“I've never been more hopeful about our future. I have never been more hopeful about America. And I ask you to sustain that hope. I'm not talking about blind optimism, the kind of hope that just ignores the enormity of the tasks ahead or the roadblocks that stand in our path. I'm not talking about the wishful idealism that allows us to just sit on the sidelines or shirk from a fight. I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.”

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

“I believe in keeping guns out of our inner cities, and that our leaders must say so in the face of the gun manfuacturer’s lobby.”
