On the fiftieth anniversary of the publication of Louis Hartz's The Liberal Tradition in America, the book remains more controversial than ever. As Philip Abbott has recently catalogued, the book has been attacked from literally every direction possible. Sean Wilentz summarizes the feelings of many when he argues that Hartz should be forgotten, or at best considered “a figure of historical interest.” Hartz has been accused of being loose with the facts, inappropriate in comparing America to continental Europe, and blind to other perspectives such as race or morality. Even those who take him seriously argue his theory is anything but a complete explanation of American political development and thought, but rather one that at best represents a mere slice of America's “multiple traditions.” Finally, of course, there is a very large and influential school of American political development that argues ideas have very little role at all in explaining politics, and for adherents to this way of thinking, Hartz is simply irrelevant. For many members of the American political development scholarly community, there is simply no room left for taking Hartz's thesis seriously any more, if there ever was.
