Poets & literary arty people don't want to hear about rational arguments for God & all that. "they'll figure it out at the Sorbonne someday". All that "irritable searching after fact & reason", or however it goes (Keats). Art feeds the appetite for love & beauty, the palpable textures of experience n' all that. I suppose where artists reside on Yeats's gyres of personal character puts them forever at odds with formal discursive argumentation & reasoning. Since soon after the Romantics, even the vague notion of the "universal Spirit" gradually dimmed beyond the ken of the intellect of the day. Now everyone feels (rightly) oppressed & bothered by aggressive fundamentalist hobgoblins.
Which, from my perspective, makes a rational evaluation of the possible existence & nature of God, paradoxically, important again for general culture (it's always been important for individuals).
