John Milbank has written here of the link between atheism, the Left, and nihilism. Regardless of Milbank’s greater point, underlying his theme is the reality that the secular, politics in general, and the Left and Right are all imagined and theory-laden metaphysical narrative frame-works that deal with life in community.
There are no neutral or theory-less ways of asserting how one should live in community. And yet, for most these theories generally go unexamined and are asserted as “just so.” The greatest thing that could happen in the West would be for the fundamentalists of both the secular and religious Left and Right to have that moment which comes to every person old enough and wise enough–that being the moment when one learns that something he just believed was true, something taken in simply as the air one breathes (everyone knows that! It’s common knowledge!) was false.
