Retiring the Argument from Reason
Another Reply to Reppert
In C. S. Lewis’s Christian Apologetics: Pro and Con, I took the con in a debate with Victor Reppert about the soundness of Lewis’s famous “argument from reason.” Reppert then extended his argument in an article for Philosophia Christi; this article is my reply. I show that Reppert’s argument fails for three reasons. (1) It “loads the die” by falsely assuming that naturalism, by definition, can't include mental causation "on the basic level." (I provide multiple examples of naturalist theories of mind that do exactly that). (2) Physical processes can reliably produce true beliefs. And (3) reasoning isn’t necessarily mental.
