Theres lots more on this subject over at The Corner. See especially Mark Steyn, Goldberg channeling Buckley, and Goldberg channeling Voegelin. (Von Heyking can tell us whether JGs emailer got Voegelin right.)
Id add this: a proselytizing atheist who exudes contempt for religious believers and wishes to debunk religion at every turn thereby gives evidence of a belief that society can prosper either in the light of reason or in the light of self-consciously understood myth. I dont think that either stance is conservative.
On the other hand, a non-believer who professes respect for religion, either out of an acknowledgement of his own fallibility and finitude or out of a recognition that widespread enlightenment is impossible, is, for all practical purposes, a conservative.
