The world exists, not for what it means but for what it is. The purpose of mushrooms is to be mushrooms, wine is in order to be wine: things are precious before they are contributory. It is a false piety that walks through creation looking only for lessons which can be applied somewhere else. To be sure, God remains the greatest good; but, for all that, the world is still good in itself. Indeed, since He does not need it, its whole reason for being must lie in its own natural goodness; He has no use for it, only delight.
