America is a nation in deep agreement and common belief. The proof lies, somewhat paradoxically, in the often tempestuous and increasingly acrimonious debate between the two main US political parties. The widening divide represented by this debate has, for many of us, defined the scope of our political views and the resultant differences for at least the past one hundred years. But even as we do tense and bruising battle, a deeper form of philosophical agreement reigns. As described by Louis Hartz in his 1955 book The Liberal Tradition in America, the nature of our debates themselves is defined within the framework of liberalism. That framework has seemingly expanded, but it is nonetheless bounded, in as much as the political debates of our time have pitted one variant of liberalism against another, which were given the labels “conservatism” and “liberalism” but which are better categorized as “classical liberalism” and “progressive liberalism.” While we have focused our attention on the growing differences between “classical” and “progressive,” we have been largely inattentive to the unifying nature of their shared liberalism.
