2000s, 2001, Freedom and Democracy Are Under Attack (September 2001)

Presidency (1977–1981), The Crisis of Confidence (1979)
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.

...
<p>At the end of the [eighteenth] century Spain had long ceased to be a great power, and France was on the way to following her example. Both were old and exhausted nations, proud but weary, looking towards the past, but lacking the true ambition—which is to be strictly differentiated from jealousy—to continue to play a creative part in the future. [The end of the eighteenth century is the time of the French Revolution, which was all about equal rights.] ... "Equal rights" are contrary to nature, are an indication of the departure from type of ageing societies, are the beginning of their irrevocable decline. It is a piece of intellectual stupidity to want to substitute something else for the social structure that has grown up through the centuries and is fortified by tradition. There is no substituting anything else for Life. After Life there is only Death.
<p>And that, at bottom, is the intention. We do not seek to alter and improve, but to destroy. In every society degenerate elements sink constantly to the bottom: exhausted families, downfallen members of generations of high breed, spiritual and physical failures and inferiors. ...
There is but one end to all the conflict, and that is death—the death of individuals, of peoples, of cultures. Our own death still lies far ahead of us in the murky darkness of the next thousand years. We Germans, situated as we are in this century, bound by our inborn instincts to the destiny of Faustian civilization, have within ourselves rich and untapped resources, but immense obligations as well. ... The true International is imperialism, domination of Faustian civilization, i.e., of the whole earth, by a single formative principle, not by appeasement and compromise but by conquest and annihilation.

1960s, Letter from a Birmingham Jail (1963)
Context: I have no fear about the outcome of our struggle in Birmingham, even if our motives are at present misunderstood. We will reach the goal of freedom in Birmingham and all over the nation, because the goal of America is freedom. Abused and scorned though we may be, our destiny is tied up with America's destiny. Before the pilgrims landed at Plymouth, we were here. Before the pen of Jefferson etched the majestic words of the Declaration of Independence across the pages of history, we were here. For more than two centuries our forebears labored in this country without wages; they made cotton king; they built the homes of their masters while suffering gross injustice and shameful humiliation -and yet out of a bottomless vitality they continued to thrive and develop. If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.
