Almost by definition, secularism cannot be a future: it’s a present-tense culture that over time disconnects a society from cross-generational purpose. Which is why there are no examples of sustained atheist civilizations. "Atheistic humanism" became inhumanism in the hands of the Fascists and Communists and, in its less malign form in today's European Union, a kind of dehumamism in which a present-tense culture amuses itself to extinction. Post-Christian European culture is already post-cultural and, with its surging Muslim populations, will soon be post-European.
Historicism runs counter to the specific capacity of the literary work to escape the limits of historical time, to allow for the cross-generational flourishing of tradition, and open the present to a multidimensional temporality.
