Abstract

Introspection is often cited as providing rational warrant for either a libertarian or a compatibilist view of human free will. C. A. Campbell argues for the former position, while Adolf Grünbaum argues for the latter. Others, such as Peter van Inwagen, attempt to show that introspection fails to provide adequate warrent for the belief that humans have free will. The paper seeks to demonstrate how all three views are mistaken, and to show just what introspective evidence rationally justifies. The epistemic status of introspective truth claims is also discussed, as is the possibility of parallels between introspection related issues and the mind body problem.
