I came across this and it reminded me of this whole discussion regarding agnosticism. Perhaps being agnostic just amounts to being an ironist.
“The artist who deploys irony tests the sophistication of his audience and divides it into two parts, those in the know and those who live in a fool’s paradise. Irony creates a privileged vantage point from which you can frame and stand aloof from a world you are too savvy to take at face value. Irony is the essence of the critical attitude, of the observer’s cool gaze; every reviewer who is not just a bourgeois cheerleader (and no reviewer will admit to being that) is an ironist.”
