The Argument from Reason: Its Scope and Limits (One More Time)

Again, I go back to Lewis on this. Lewis accepted the AFR against naturalism, and then accepted Absolute Idealism, which was extremely popular in his time. Then he found fault with Idealism and became a theist, and then finally a Christian. His argument against naturalism was a step on the way to theism, eliminating one of the major options. But he didn't take step into theism until later.




I am primarily concerned with what I would call the "great divide" between world-views for whom the mental is a basic cause, and world-views in which the mental is not a basic cause. If the AFR shows problems for the latter type of position, then I think the epistemic likelihood of theism becomes enhanced, as do all other "mentalistic" options.



I understand "naturalism" to encompass those world-views that are, at bottom, anti-mentalistic.



So we can distinguish two propositions:



A) The basic causes of the universe are mental in nature. They are inheretly perspectival, having a subject. They are inherently normative. Something being good or bad, or thought good or bad, has something to do with what goes on. They are intentional. What something is about makes a basic difference as to what happens in the world. They are also purposive. Purposes in human thought and action are not "skyhooks" that have to be analyzed out in favor of cranes. They are ground-level reasons why things happen.



b) What is fundamentally real is not inherently perspectival, is not inherently intentional, is not inherently normative, and is not inherently purposive. The appearance that these mental realities are operative in our world is a byproduct of biological evolution, and at the end of the day the skyhooks have to be replaced by cranes.



I have never said that you get theism automatically if the AFR is an effective argument for preferring A to B. When people point out non-theistic alternatives that are compatible with A, as if that were an answer to me, I have to say, with C. S. Lewis, "How many times does a man have to say something before he is safe from the accusation of having said exactly the opposite?"
