Humean compatibilism is the combination of a Humean position on laws of nature and the thesis that free will is compatible with determinism. This article's aim is to situate Humean compatibilism in the current debate among libertarians, traditional compatibilists, and semicompatibilists about free will. We argue that a Humean about laws can hold that there is a sense in which the laws of nature are 'up to us' and hence that the leading style of argument for incompatibilism?the consequence argument?has a false premiss. We also display some striking similarities between Humean compatibilism and libertarianism, an incompatibilist view. For example, standard libertarians face a problem about luck, and we show that Humean compatibilists face a very similar problem.

Libertarianism Today, by Jacob Huebert (Santa Barbara, CA: Praeger, 2010), is an excellent introduction to libertarianism. In contrast to many other recent books about libertarianism, a consistent non-compromising libertarianism is defended throughout this book.

The Consequence Argument is a staple in the defense of libertarianism, the view that free will is incompatible with determinism and that humans have free will. It is often thought that libertarianism is consistent with a certain naturalistic view of the world — that is, that libertarian free will can be had without metaphysical commitments beyond those pro- vided by our best (indeterministic) physics. In this paper, I argue that libertarians who endorse the Consequence Argument are forced to reject this naturalistic worldview, since the Consequence Argument has a sis- ter argument — I call it the Supervenience Argument — which cannot be rejected without threatening either the Consequence Argument or the naturalistic worldview in question.

Compatibilism is the doctrine that the doctrine of determinism is logically consistent with the doctrine of libertarianism. Determinism is the doctrine that every being and event is brought about by causes other than itself. Libertarianism is the doctrine that some human actions are free. Was Descartes a compatibilist? There is no doubt that he was a libertarian: his works are full of professions of freedom, human as well as divine. And though he held that God has no cause other than himself, Descartes thought that everything apart from God is externally caused: he was a determinist with respect to the created universe. So it appears, assuming him consistent with himself, that Descartes must have been a compatibilist. And indeed, there are passages in his writings in which he appears explicitly to affirm that he is. Since both Descartes’s libertarianism and his determinism are complex doctrines, however, his view of the relation between them is complex as well.

In this paper I criticize libertarianism and skepticism about free will. The criticism of libertarianism takes some steps towards filling in an argument that is often mentioned but seldom developed in any detail, the argument that libertarianism is a scientifically implausible view. I say "take some steps" because I think the considerations I muster (at most) favor a less ambitious relative of that argument. The less ambitious claim I hope to motivate is that there is little reason to believe that extant libertarian accounts satisfy a standard of naturalistic plausibility, even if they do satisfy a standard of naturalistic compatibility. The argument against skepticism about free will tries to show (1) perhaps the most prominent form of skeptical argument against the existence of free will does not work, and (2) there is a good general argument against skepticism about free will.
