Why is debate over the free will problem so intractable? In this broad and stimulating look at the philosophical enterprise, Richard Double uses the free will controversy to build on the subjectivist conclusion he developed in The Non-Reality of Free Will (OUP 1991). Double argues that various views about free will–e.g., compatibilism, incompatibilism, and even subjectivism–are compelling if, and only if, we adopt supporting metaphilosophical views. Because metaphilosophical considerations are not provable, we cannot show any free will theory to be most reasonable. Metaphilosophy and Free Will deconstructs the free will problem and, by example, challenges philosophers in other areas to show how their philosophical argumentation can succeed.
