To whistle in the dark is more than just to try to convince yourself that dark is not all there is. It is also to remind yourself that dark is not all there is, or the end of all that is, because even in the dark there is hope. Even in the dark you have the power to whistle. And something that seems more than just your own power because it’s powerful enough to hold back the dark just a little. The tunes you whistle in the dark are the images you make of that hope, that power. They are the books you write. And in the same way, faith could be called a kind of whistling in the dark.
