Abstract

Are free will and determinism compatible? Philosophical focus on this deceptively simple `compatibility question' has historically been so pervasive that the entire free will debate is now standardly framed in its terms - that is, as a dispute between compatibilists, who answer the question affirmatively, and incompatibilists, who respond in the negative. This dissertation, in contrast, adopts a position that I call `descriptive variantism,' according to which prevailing notions of free will exhibit significant aspects of both compatibilism and incompatibilism. My formulation and defense of this position provides a framework for considering several important issues that cannot be adequately addressed on the traditional conception of the free will debate. The theoretical advantages of descriptive variantism become apparent, I argue, only after adopting needed refinements to the compatibility question itself. As it stands, this question conflates at least two distinct issues: whether free will, as ordinarily understood, does in fact conflict with determinism, and whether free will should be taken to involve such a conflict. The vast majority of work in this area, I maintain, implies that (a) the shared notion of free will exemplified in everyday usage conforms exclusively to either compatibilism or incompatibilism, and (b) the (singular) position suggested by this shared notion constitutes the most adequate response to the compatibility question. This is a mistake: it ignores several other possibilities, among them the prospect that multiple `shared notions' are implicated in the complex network of judgments, attitudes, and social practices related to free will. Having reformulated various aspects of the free will debate in ways that address these issues, I go on to argue that no single account of free will can underwrite the broad range of phenomena associated with this notion. Most importantly, I maintain that contextual features, especially those related to abstraction and concreteness, engender significantly different notions of free will: abstract contexts tend to elicit judgments and other behaviors conducive to incompatibilism, while concreteness often promotes tendencies best captured by compatibilist theories. I support these empirical claims primarily by drawing out the conceptual implications of recent experimental work on these topics in a variety of disciplines, including philosophy, psychology, and neuroscience, and defend my interpretation against alternative accounts that purport to `explain away' the contextual differences exhibited in the experimental data. If these claims are correct, then the fundamental conflicts inherent in prevailing notions of free will have the potential to manifest themselves in some highly problematic ways. For example, criminal laws enacted in abstract contexts may presuppose constraints on free agency deeply at odds with those implicitly adopted by jurors evaluating concrete violations of these laws. I attempt to make some preliminary progress on these vexing, but vital, issues by suggesting that revision towards compatibilism represents an initially appealing method of resolving some of these practical difficulties. Importantly, though, this suggestion is tentative, particularly insofar as the extent to which such revision is ultimately desirable, feasible, or even psychologically possible remains unclear. Further consideration of these issues thus constitutes an important avenue for future research
