The Argument from Reason to God

by Paul Gould

Naturalism is the view that there are no supernatural beings. The natural world is causally closed: there is nothing outside the box, nothing transcendent, nothing that impinges on the world from beyond. Thus, the basic level of analysis is physics: all reality, at rock bottom is captured by tiny bits of matter (quarks? strings?) that are properly understood by the discipline of physics. On this picture, a deep puzzle—conflict even—arises: how is it that our world is intelligible, if man is just a product of chance and necessity? Whence reason?

As C. S. Lewis put it in his book Miracles:

Thus a strict materialism refutes itself for the reason given long ago by Professor Haldane: “If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true . .  . and hence I have no reason for supposing my brain to be composed of atoms.” (Possible Worlds, p. 209) . . . [Naturalism] discredits our processes of reasoning or at least reduces their credit to such a humble level that it can no longer support Naturalism itself.[1]

Lewis is noting a deep conflict between naturalism and the reality of reason. On the other hand, on theism, reason and intelligence are a natural fit: A rational God exists and part of what it means to be created in the image of this rational God is to possess intelligence.
