Patrick J. Deneen in The Hedgehog Review:
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.
While classical liberalism looks back to a liberalism achieved and lost—particularly the founding philosophy of America that stressed natural rights, limited government, and a relatively free and open market, “progressive” liberalism longs for a liberalism not yet achieved, one that strives to transcend the limitations of the past and even envisions a transformed humanity, its consciousness enlarged, practicing what Edward Bellamy called “the religion of solidarity.”1 As Richard Rorty envisioned in his aptly titled 1998 book Achieving Our Country, liberal democracy “is the principled means by which a more evolved form of humanity will come into existence.… Democratic humanity…has ‘more being’ than predemocratic humanity. The citizens of a [liberal] democratic, Whitmanesque society are able to create new, hitherto unimagined roles and goals for themselves.”
