In this paper I shall define a thesis I shall call 'determinism', and argue that it is incompatible with the thesis that we are able to act otherwise than we do (i.e., is incompatible with 'free will'). Other theses, some of them very different from what I shall call 'determinism', have at least an equal right to this name, and, therefore, I do not claim to show that every thesis that could be called 'determinism' without historical impropriety is incompatible with free will. I shall, however, assume without argument that what I call 'determinism' is legitimately so called. In Part I, I shall explain what I mean by 'determinism'. In Part II, I shall make some remarks about 'can'. In Part III, I shall argue that free will and determinism are incompatible. In Part IV, I shall examine some possible objections to the argument of Part III. I shall not attempt to establish the truth or falsity of determinism, or the existence or nonexistence of free will.

In this paper, I argue against Peter van Inwagen’s claim (in “Free Will Remains a Mystery”), that agent-causal views of free will could do nothing to solve the problem of free will (specifically, the problem of chanciness). After explaining van Inwagen’s argument, I argue that he does not consider all possible manifestations of the agent-causal position. More importantly, I claim that, in any case, van Inwagen appears to have mischaracterized the problem in some crucial ways. Once we are clear on the true nature of the problem of chanciness, agent-causal views do much to eradicate it.

Peter van Inwagen contends that free will is a mystery. Here I present an argument in the spirit of van Inwagen's. According to the Assimilation Argument, libertarians cannot plausibly distinguish causally undetermined actions, the ones they take to be exercises of free will, from overtly randomized outcomes of the sort nobody would count as exercises of free will. I contend that the Assimilation Argument improves on related arguments in locating the crucial issues between van Inwagen and libertarians who hope to demystify free will, while avoiding objections these arguments have faced.

Peter van Inwagen has offered two versions of an influential argument that has come to be called ‘the Consequence Argument’. The Consequence Argument purports to demonstrate that determinism is incompatible with free will.1 It aims to show that, if we assume determinism, we are committed to the claim that, for all propositions p, no one has or ever had any choice about p. Unfortunately, the original Consequence Argument employed an inference rule (the β-rule) that was shown to be invalid. (McKay and Johnson 1996) In response, van Inwagen revised his argument. I shall argue that the conclusion of the revised Consequence Argument is wholly independent of the premiss of determinism, and hence that the revised Consequence Argument is useless in showing that determinism is incompatible with free will.
