宜修: American exceptionalism is the theory that the United States is especially unique or special compared to other nations, to a degree that merits particular attention.[2] In this view, America's exceptionalism stems from its emergence from a revolution, becoming what political scientist Seymour Martin Lipset called "the first new nation"[3] and developing a uniquely American ideology, "Americanism", based on liberty, egalitarianism, individualism, republicanism, populism and laissez-faire.[4] This ideology itself is often referred to as "American exceptionalism."[4] (9-13 10:46)
