The origins of the phrase “American exceptionalism” are not especially obscure. The French sociologist Alexis de Tocqueville, observing this country in the 1830s, said that Americans seemed exceptional in valuing practical attainments almost to the exclusion of the arts and sciences. The Soviet dictator Joseph Stalin, on hearing a report by the American Communist Party that workers in the United States in 1929 were not ready for revolution, denounced “the heresy of American exceptionalism.”
In 1996, the political scientist Seymour Martin Lipset took those hints from Tocqueville and Stalin and added some of his own to produce his book American Exceptionalism: A Double-Edged Sword. The virtues of American society, for Lipset -- our individualism, hostility to state action, and propensity for ad hoc problem-solving -- themselves stood in the way of a lasting and prudent consensus in the conduct of American politics.
