The Importance of Divine Simplicity

Bishop arn: God can have no contingent knowledge or action, for everything about him is essential to him. Since god is absolutely simple across possible worlds, ever knowing or doing anything differently, motal distinctions collapse. Bishop arn tries to avert this unwelcome consequence by appealing to the tomistic doctrine that, while creatures are really related to god, god is not really related to creatures. The problem with this doctrine is that it makes the exist of creatures inexplicable. They come too late in the order of explanation to account for why they exist or not. It follows that on tombism, there is no explanation of the existence of creatures or the differences between possible worlds which seems absurd.
