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.

The Assimilation Argument purports to show that libertarians cannot plausibly distinguish supposed exercises of free will from random outcomes that nobody would count as exercises of free will. If this argument is sound, libertarians should either abandon their position or else concede that free will is a mystery. Drawing on a parallel with the Manipulation Argument against compatibilism, Christopher Franklin has recently contended that the Assimilation Argument is unsound. Here I defend the Assimilation Argument and the Rollback Argument, a second (...) challenge to libertarianism that Franklin rejects. My aim in doing so is to underscore the force of these challenges, and thereby to resist what appears to be an emerging trend in the literature. By not coming to grips with the kind of power that libertarians must secure, many writers have recently downplayed or dismissed the pressing worry for libertarianism. (shrink)

Famed so-called 'Frankfurt-type examples' have been invoked to cast doubt on the principle that a person is morally responsible for what she has done only if she could have done otherwise. Many who disagree that the examples are successful in this respect argue that these examples succumb to a deadly dilemma. I uncover and assess libertarian assumptions upon which the 'dilemma objection' is based. On exposing these assumptions, it becomes clear that various sorts of libertarian are no longer entitled to (...) one or the other horns of the dilemma. (shrink)

In this paper I seek to defend libertarianism about free will and moral responsibility against two well-known arguments: the luck argument and the Mind argument. Both of these arguments purport to show that indeterminism is incompatible with the degree of control necessary for free will and moral responsibility. I begin the discussion by elaborating these arguments, clarifying important features of my preferred version of libertarianism—features that will be central to an adequate response to the arguments—and showing why a strategy of (...) reconciliation (often referred to as “deliberative libertarianism”) will not work. I then consider four formulations of the luck argument and find them all wanting. This discussion will place us in a favorable position to understand why the Mind argument also fails. (shrink)

The Luck Argument is among the most influential objections to the main brand of libertarianism about metaphysical freedom and moral responsibility. In his work, Alfred Mele [2006. Free will and luck . Oxford: Oxford University Press] develops - and then attempts to defeat - the literature's most promising version of the Luck Argument. After explaining Mele's version of the Luck Argument, I present two objections to his novel reply to the argument. I argue for the following two claims: (1) Mele's (...) reply is either otiose or undermined by his own defense of the Luck Argument from a different objection and (2) Mele's reply turns out to lack the form required to engage the step of the Luck Argument it targets. Having shown that the failure of Mele's novel attack is overdetermined, I close by defending a different (and, I believe, decisive) objection to the Luck Argument - which, as it happens, lurks right under Mele's nose.

In his (2004), Randolph Clarke assesses an important version of an influential argument against libertarianism about metaphysical freedom. Clarke calls the anti-libertarian argument he evaluates the Contrast Argument. It targets the following claim: there could be an undetermined free act done by S such that S would have freely done something else had S not done the act in question. This modal claim will be endorsed not only by proponents of main brands of libertarianism, but also by action theorists of (...) other stripes – including many compatibilists. Clarke aims to defend the Contrast Argument from a prominent objection by developing a novel case for the premise under attack. I show that Clarke's attempted defense of the Contrast Argument fails, thereby protecting the relevant libertarian and compatibilist positions. In brief, Clarke's argument depends on an ambiguous principle, each available reading of which leaves some or other premise of his argument unjustified. (shrink)

This work develops a philosophically credible and psychologically realisable account of control that is necessary for moral responsibility. We live, think, and act in an environment of subjective uncertainty and limited information. As a result, our decisions and actions are influenced by factors beyond our control. Our ability to act freely is restricted by uncertainty, ignorance, and luck. Through three articles, I develop a naturalistic theory of control for action as a process of error minimisation that extends over time. Thus (...) conceived, control can serve to minimise the influence of luck on action and enable freedom in uncertainty. -/- In Article 1, Thor Grünbaum and I argue for a psychologically plausible account of the kind of control that is necessary for moral responsibility. We begin by establishing the relationship between agentive contribution and responsibility-level control. One way to determine whether one the right kind and degree of control to be morally responsible is to track one’s degree of contribution to an action. However, a psychologically plausible account of control in terms of agentive contribution may seem to contradict the types of functional-mechanistic explanations used in cognitive science. In cognitive psychology and cognitive neuroscience, personal-level capacities are explained by a set of sub-personal mechanisms. Often, such explanations leave no room for a contribution by the agent. By integrating insights from theories of cognitive control and incorporating them into a philosophical account of intentions, we propose a way of thinking about the distribution of cognitive control resources as something the agent does. -/- Article 2 argues that a classic argument concerning luck, originally aimed at libertarianism, generalises beyond any specific theory of free will, and regardless of whether determinism or indeterminism is true. I call this mental luck. Because we all make decisions under conditions of relative uncertainty and limited information, it is possible for an agent to make decisions that are contrary to their own motivation. In such situations, it may be a matter of luck whether the agent makes the right decision. Mentally lucky decisions are not rationally governed by attitudes within the agent's perspective, and thus, may be indistinguishable from unlucky ones. From the perspective of the agent, such decisions may resemble the outcome of a lottery. Therefore, mental luck poses a challenge to most prominent theories of free action and moral responsibility. -/- Finally, article 3 engages with the issue of resultant luck, namely luck in how things turn out. Resultant luck raises a challenge for theories of moral responsibility because its existence suggests that one may be responsible for factors beyond one’s control. Prominent responses to resultant luck led to a choice between internalism and scepticism. I argue that familiar cases of resultant luck are based on the assumption that actions are events. Instead, I propose an alternative ontology of action as an ongoing goal-directed process with a many-shots structure. Described this way, cases of resultant luck are not representative of ordinary action. The proposal of action as a many-shots process is consistent with predictive coding, a cognitive architecture which centres around error minimisation. Under this framework, cases of resultant more luck are no longer failures of action, but rather anticipated errors to be settled within the ordinary process of action. (shrink)
