“For the African-American community, that path means embracing the burdens of our past without becoming victims of our past. It means continuing to insist on a full measure of justice in every aspect of American life. But it also means binding our particular grievances - for better health care, and better schools, and better jobs - to the larger aspirations of all Americans: the white woman struggling to break the glass ceiling, the white man who's been laid off, the immigrant trying to feed his family. And it means also taking full responsibility for our own lives - by demanding more from our fathers, and spending more time with our children, and reading to them, and teaching them that while they may face challenges and discrimination in their own lives, they must never succumb to despair or cynicism. They must always believe that they can write their own destiny.”

Context: Our identity as a nation – unlike many other nations – is not determined by geography or ethnicity, by soil or blood. Being an American involves the embrace of high ideals and civic responsibility. We become the heirs of Thomas Jefferson by accepting the ideal of human dignity found in the Declaration of Independence. We become the heirs of James Madison by understanding the genius and values of the U. S. Constitution. We become the heirs of Martin Luther King Jr. by recognizing one another not by the color of their skin but by the content of their character. This means people of every race, ethnicity and religion can be fully and equally American. It means that bigotry or white supremacy in any form is blasphemy against the American creed. It means the very identity of our nation depends on the passing of civic ideals to the next generation.

1910s, Address to the Knights of Columbus (1915)
Context: The one absolutely certain way of bringing this nation to ruin, of preventing all possibility of its continuing to be a nation at all, would be to permit it to become a tangle of squabbling nationalities, an intricate knot of German-Americans, Irish-Americans, English-Americans, French-Americans, Scandinavian-Americans or Italian-Americans, each preserving its separate nationality, each at heart feeling more sympathy with Europeans of that nationality, than with the other citizens of the American Republic. The men who do not become Americans and nothing else are hyphenated Americans; and there ought to be no room for them in this country. The man who calls himself an American citizen and who yet shows by his actions that he is primarily the citizen of a foreign land, plays a thoroughly mischievous part in the life of our body politic. He has no place here; and the sooner he returns to the land to which he feels his real heart allegiance, the better it will be for every good American. There is no such thing as a hyphenated American who is a good American. The only man who is a good American is the man who is an American and nothing else.

Context: We know the strength of America. We are strong. We can regain our unity. We can regain our confidence. We are the heirs of generations who survived threats much more powerful and awesome than those that challenge us now. Our fathers and mothers were strong men and women who shaped a new society during the Great Depression, who fought world wars, and who carved out a new charter of peace for the world.
We ourselves are the same Americans who just 10 years ago put a man on the Moon. We are the generation that dedicated our society to the pursuit of human rights and equality. And we are the generation that will win the war on the energy problem and in that process rebuild the unity and confidence of America.
We are at a turning point in our history. There are two paths to choose. One is a path I've warned about tonight, the path that leads to fragmentation and self- interest. Down that road lies a mistaken idea of freedom, the right to grasp for ourselves some advantage over others. That path would be one of constant conflict between narrow interests ending in chaos and immobility. It is a certain route to failure.
All the traditions of our past, all the lessons of our heritage, all the promises of our future point to another path, the path of common purpose and the restoration of American values. That path leads to true freedom for our Nation and ourselves. We can take the first steps down that path as we begin to solve our energy problem.
Energy will be the immediate test of our ability to unite this Nation, and it can also be the standard around which we rally. On the battlefield of energy we can win for our Nation a new confidence, and we can seize control again of our common destiny.
