In this introduction to the volume, Jager argues that secularism has remained an obscure topic within romantic studies. Noting that 'a genealogy of romantic secularism has yet to be written,' Jager sketches some aspects of such a genealogy by noting the persistence of romantic thinking—about the symbol, for example—in secular thinking. Cosmopolitanism, he notes, has been more widely considered alongside romanticism, but here again the relationship of secularism to 'romantic cosmopolitanism' has tended to remain invisible. Is cosmopolitanism part of a secular project? Or do the conditions of postmodernity in fact make possible a religious cosmopolitanism of a kind anticipated by some romantic texts? This essay appears in _Secularism, Cosmopolitanism, and Romanticism_, a volume of _Romantic Circles Praxis Series_, prepared exclusively for Romantic Circles (http://www.rc.umd.edu/), University of Maryland.
