These are theological questions without theological answers, and, if the atheist is not supposed to entertain them, then, for slightly different reasons, neither is the religious believer. Religion assumes that they are not valid questions because it has already answered them; atheism assumes that they are not valid questions because it cannot answer them. But as one gets older, and parents and peers begin to die, and the obituaries in the newspaper are no longer missives from a faraway place but local letters, and one’s own projects seem ever more pointless and ephemeral, such moments of terror and incomprehension seem more frequent and more piercing, and, I find, as likely to arise in the middle of the day as the night.
