Abstract

Over the past half century, I have been developing and defending a libertarian view of free will that is incompatible with determinism. In the past decade, I have made changes to this view in response to the large critical literature that has developed around it since the publication of my book The Significance of Free Will (Oxford University Press, 1996). This paper describes and defends some of the more significant of these new aspects of my view. Section 1 describes the problem of free will as conceived traditionally and in modern times, as well as the various competing positions on it (compatibilist, libertarian, skeptical, and so forth). In section 2 I concede to compatibilists that there are many meanings of freedom, and that many of them could exist in a thoroughly determined world. But there is one kind of traditional freedom, I argue, that could not exist in a thoroughly determined world—freedom of will. Sections 3 and 4 explain what this freedom of will requires and why it is important. Sections 5–11 then discuss and answer many arguments that have been made against the possibility of such a free will requiring indeterminism.
