‘What do you believe?’ For most of us the question is embarrassing. Even the minority who subscribe to a particular faith, or denomination within one, find it difficult to distinguish between what they ought to believe and what, at root, they actually believe.
For the non-believer, perhaps, the question deserves to be more embarrassing than it usually appears to be. For conversational purposes he can usually get away with declaring himself only … a non-believer. Yet in truth very few believe nothing. Nothing is a very difficult thing to believe in. Even those who deny the possibility of meaning, in the epistemological sense, to any metaphysical proposition tend in practice to have half-thought, half-felt notions about ultimate reality. There are indeed many kinds and levels of non-belief just as there are of belief.
