Atheists typically claim that science is on their side. Religion, we are told, has been at war with science from the beginning. While scholars have rejected the warfare metaphor, the history of science raises a bigger problem. Several key ideas that arose during the scientific revolution had a theological basis: laws of nature, the uniformity and rationality of nature, and more. Atheists can continue to use such ideas, just as some continue to invoke moral norms while denying any object basis for ethics. But can an atheist rationally believe that our best scientific theories are literally true rather than, say, merely useful? Contrary to the conventional wisdom, the most natural home for a robust view of science is theism.
