American exceptionalism

American exceptionalism is one of three related ideas. The first is that the history of the United States is inherently different from other nations. In this view, American  exceptionalism stems from its emergence from the American Revolution, thereby becoming what political scientist Seymour Martin Lipset called "the first new nation" and developing a uniquely American ideology, "Americanism", based on liberty, egalitarianism, individualism, republicanism, democracy and laissez-faire for business. This ideology itself is often referred to as "American exceptionalism." Second is the idea that America has a unique mission to transform the world. As Abraham Lincoln put it in the Gettysburg address (1863), Americans have a duty to see that "government of the people, by the people, for the people, shall not perish from the earth." Third is the sense that its history and its mission give the United States a superiority over other nations.
