But it is not possible to know that by looking at the natural world alone. The question of purpose is closely related to the question of whether something like the God of Western monotheistic religions can be known to exist by studying the order, goodness, and grandeur of the universe. Already around 1750 David Hume pointed out that if one is looking at evidence of design, then all of the evidence must be taken into account: not only order and goodness but disorder and evil as well. He seems to think that some sort of creator is possible (in his Dialogues Concerning Natural Religion, published posthumously in 1779, it is not clear which character represents Hume’s own views). But if so, we can know next to nothing about the creator’s qualities: an intelligence, for all we know, as much like ours as our intelligence is like the rotting of a turnip–one deity or a team; alive or dead; a juvenile or superannuated deity. Nothing can be known of any plan for the future perfection of the world or the human condition.
