“This democracy we have is a precious thing. For all the arguments and all the doubts and all the cynicism that’s out there today, we should never forget that as Americans, we enjoy more freedoms and opportunities than citizens in any other nation on Earth. (Applause.) We are free to speak our mind and worship as we please. We are free to choose our leaders, and criticize them if they let us down. We have the chance to get an education, and work hard, and give our children a better life.None of this came easy. None of this was preordained. The men and women who sat in your chairs 10 years ago and 50 years ago and 100 years ago –- they made America possible through their toil and their endurance and their imagination and their faith. Their success, and America’s success, was never a given. And there is no guarantee that the graduates who will sit in these same seats 10 years from now, or 50 years from now, or 100 years from now, will enjoy the same freedoms and opportunities that you do. You, too, will have to strive. You, too, will have to push the boundaries of what seems possible. For the truth is, our nation’s destiny has never been certain.What is certain -– what has always been certain -– is the ability to shape that destiny. That is what makes us different. That is what sets us apart. That is what makes us Americans -– our ability at the end of the day to look past all of our differences and all of our disagreements and still forge a common future. That task is now in your hands, as is the answer to the question posed at this university half a century ago about whether a free society can still compete.”

“And to all those who have wondered if Americas beacon still burns as bright - tonight we proved once more that the true strength of our nation comes not from our the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity, and unyielding hope.For that is the true genius of America - that America can change. Our union can be perfected. And what we have already achieved gives us hope for what we can and must achieve tomorrow.”

“What makes us exceptional, what makes us America is our allegiance to an idea articulated in a declaration made more than two centuries ago. We hold these truths to be self-evident, that all men are created equal.”

“This country of ours has more wealth than any nation, but that's not what makes us rich. We have the most powerful military on Earth, but that's not what makes us strong. Our universities and our culture are the envy of the world, but that's not what keeps the world coming to our shores. It is that American spirit - that American promise - that pushes us forward even when the path is uncertain; that binds us together in spite of our differences; that makes us fix our eye not on what is seen, but what is unseen, that better place around the bend”

“The problem is that this kind of vilification and over-the-top rhetoric closes the door to the possibility of compromise. It undermines democratic deliberation. It prevents learning –- since, after all, why should we listen to a “fascist,” or a “socialist,” or a “right-wing nut,” or a left-wing nut”? It makes it nearly impossible for people who have legitimate but bridgeable differences to sit down at the same table and hash things out. It robs us of a rational and serious debate, the one we need to have about the very real and very big challenges facing this nation. It coarsens our culture, and at its worst, it can send signals to the most extreme elements of our society that perhaps violence is a justifiable response. So what do we do? As I found out after a year in the White House, changing this type of politics is not easy. And part of what civility requires is that we recall the simple lesson most of us learned from our parents: Treat others as you would like to be treated, with courtesy and respect. (Applause.) But civility in this age also requires something more than just asking if we can’t just all get along.”

“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.”

“All men are created equal. It is what you do from there that makes the difference. We are all free agents in life. We make our own decisions. We control our own destiny.”
