Democracy in America was published in two volumes, the first in 1835 and the other in 1840. It was immediately popular in both Europe and the United States, while also having a profound impact on the French population. By the twentieth century, it had become a classic work of political science, social science, and history. It is a commonly assigned reading for undergraduates of American universities majoring in the political or social sciences, and part of the introductory political theory syllabus at Cambridge, Oxford, Princeton and other institutions. In the introduction to his translation of the book, Harvard Professor Harvey C. Mansfield calls it "at once the best book ever written on democracy and the best book ever written on America."
Tocqueville's work is often acclaimed for making a number of astute predictions. He anticipates the potential acrimony over the abolition of slavery that would tear apart the United States and lead to the American Civil War as well as the eventual superpower rivalry between the United States and Russia, which exploded after World War II and spawned the Cold War.
Noting the rise of the industrial sector in the American economy, Tocqueville, some scholars have argued, also correctly predicted that an industrial aristocracy would rise from the ownership of labor. He warned that '...friends of democracy must keep an anxious eye peeled in this direction at all times', observing that the route of industry was the gate by which a newfound wealthy class might potentially dominate, although he himself believed that an industrial aristocracy would differ from the formal aristocracy of the past.
On the other hand, Tocqueville proved shortsighted in noting that a democracy's equality of conditions stifles literary development. In spending several chapters lamenting the state of the arts in America, he fails to envision the literary Renaissance that would shortly arrive in the form of such major writers as Edgar Allan Poe, Henry David Thoreau, Ralph Waldo Emerson, Herman Melville, Nathaniel Hawthorne and Walt Whitman. Equally, in dismissing the country's interest in science as limited to pedestrian applications for streamlining the production of material goods, he failed to imagine America's burgeoning appetite for pure scientific research and discovery.
According to Tocqueville, democracy had some unfavorable consequences: the tyranny of the majority over thought, a preoccupation with material goods, and isolated individuals.
