I have argued elsewhere, as my colleague Trent Dougherty also has and earlier, that when we understand simplicity rightly, theism makes for a simpler theory than naturalism. However, suppose I am wrong, and naturalism is the simpler theory. Is that a reason to think naturalism true? I suspect not. For it is theism that explains how simplicity can be a guide to truth (say, because of God's beauty and God's desire to produce an elegant universe), while on naturalism we should not think of simplicity as a guide to truth, but at most as a pragmatic benefit of a theory. Thus to accept naturalism for the sake of simplicity is to cut the branch one is sitting on.
