Neil Levy mounts two arguments against Robert Kane’s influential libertarian theory. According to the first, because Kanean self-forming actions are undetermined, there can be no contrastive explanation for why agents choose as they do rather than otherwise, in which case how they choose appears to be a matter of luck. According to the second, if one grants Kane the claim that agents are responsible for their undetermined choices in virtue of the fact that they made efforts of will to choose (...) them, the fact that agents engage in dual efforts of will leads to an implausible doubling of the agent’s responsibility. We defend Kane from both objections. We argue against the first by clarifying the nature of contrastive explanation in the context of Kane’s theory and we argue against the second by showing that the kind of doubling of responsibility implied by an agent’s dual efforts of will is, in fact, innocuous.

The purpose of this essay is to respond to critiques of my recent book (Free Will as an Open Scientific Problem) put forward by Michael McKenna, Derk Pereboom, and Bob Kane in an Author-Meets-Critics session at the 2011 Pacific Division meeting of the APA.

The Luck Objection is an influential family of challenges to libertarianism. In recent years, discussions of the Luck Objection have reached an impasse of sorts. On one hand, existing responses to the objection have failed to satisfy libertarianism’s many critics. On the other hand, a growing number of libertarians seem unimpressed by existing formulations of the objection. To break the impasse, I present a two-stage version of the objection. The first stage has the limited objective of showing that supposed exercises (...) of free will resemble certain nonactions in being truly random outcomes. The second stage seeks to show that we aren’t morally responsible for supposed exercises of free will if they are truly random outcomes. The leading idea is that such actions, qua truly random outcomes of our prior mental states, don’t meet a plausible guidance requirement for morally responsible agency. (shrink)

Libertarian free will is, roughly, the view that agents cause actions to occur or not occur: Maddy’s decision to get a beer causes her to get up off her comfortable couch to get a beer, though she almost chose not to get up. Libertarian free will notoriously faces the luck objection, according to which agential states do not determine whether an action occurs or not, so it is beyond the control of the agent, hence lucky, whether an action occurs or (...) not: Maddy’s reasons for getting beer in equipoise with her reasons to remain in her comfortable seat do not determine that she will get up or stay seated, so it seems beyond her control, hence lucky, that she gets up. In this paper I consider a sub-set of the luck objection called the Physical Indeterminism Luck Objection, according to which indeterministic physical processes cause actions to occur or not, and agent’s lack control over these indeterministic physical processes, so agent’s lack control over, hence it is lucky, whether action occurs or not. After motivating the physical indeterminism luck objection, I consider responses from three recent event-causal libertarian models, and conclude that they fail to overcome the problem, though one promising avenue is opened up.

I recently argued that reductive physicalist versions of libertarian free will face a physical indeterminism luck objection. John Lemos claims that one potential advocate of reductive physicalist libertarianism, Robert Kane, avoids this physical indeterminism luck objection. I here show how the problem remains.

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes. Though libertarian free will and nonreductive physicalism have overlapping subject matter, and while libertarian free will is currently trending at the same time as nonreductive physicalism is a dominant metaphysical posture, there are few sustained expositions of a nonreductive physicalist model of libertarian (...) free will – indeed some tell against such an admixture. This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (shrink)

Dwayne Moore (2021) argues that libertarians about free will who are reductive physicalists cannot make proper sense of free will. In doing so, he presents what he calls “the physical indeterminism luck objection” to libertarian free will. He goes on to consider three different contemporary naturalistic approaches to libertarian free will (LFW) – those of Christopher Franklin, Mark Balaguer, and Robert Kane – and argues that if understood as reductive physicalist views they all fall prey to this objection. While it’s (...) not entirely clear that Kane is a reductive physicalist, it is clear that he would reject any kind of eliminative materialism or eliminative physicalism (Kane 1996, 147). Regardless, in this essay I argue that even if Kane’s view is a kind of reductive physicalist view, it is immune to the arguments made in Moore’s essay. (shrink)
