"...Alan, the first winter we knew him, stood at my desk in the Cathedral library and remarked, "I think you and Hugh live more existentially than most people." I felt we'd made it: we, like Sartre and Camus and Kierkegaard, were existential; we were really with it. It doesn't matter that I'm still not quite sure what living existentially means, though I have a suspicion that it's not far from living ontologically, because it's one of those words that's outside the realm of provable fact and touches on mystery. Nothing important is completely explicable."
