My topic lies on conceptual terrain that is quite familiar to philosophers. For others, a bit of background may be in order. In light of what has filtered down from quantum mechanics, few philosophers today believe that the universe is causally deterministic. That is, to use Peter van Inwagen's succinct definition of “determinism,” few philosophers believe that “there is at any instant exactly one physically possible future.” Even so, partly for obvious historical reasons, philosophers continue to argue about whether free (...) will and moral responsibility are compatible with determinism. Compatibilists argue for compatibility, and incompatibilists argue against it. Some incompatibilists maintain that free will and moral responsibility are illusions. But most are libertarians, libertarianism being the conjunction of incompatibilism and the thesis that at least some human beings are possessed of free will and moral responsibility. (shrink)

Consider the following principle: (LP) If an action is undetermined at a time t, then its happening rather than not happening at t would be a matter of chance or luck, and so it could not be a free and responsible action. This principle (which we may call the luck principle, or simply LP) is false, as I shall explain shortly. Yet it seems true.

This essay challenges the widely accepted principle that a person is morally responsible for what he has done only if he could have done otherwise. The author considers situations in which there are sufficient conditions for a certain choice or action to be performed by someone, So that it is impossible for the person to choose or to do otherwise, But in which these conditions do not in any way bring it about that the person chooses or acts as he (...) does. In such situations the person may well be morally responsible for what he chooses or does despite his inability to choose or to do otherwise. Finally the author considers certain suggestions for revising the principle he rejects or for replacing it with a principle of an altogether different kind. (shrink)

Typical incompatibilists about moral responsibility and determinism contend that being basically morally responsible for a decision one makes requires that, if that decision has proximal causes, it is not deterministically caused by them. This article develops a problem for this contention that resembles what is sometimes called the problem of present (or cross-world) luck. However, the problem makes no reference to luck nor to contrastive explanation. This article also develops a solution.

Key elements of Randolph Clarke's libertarian account of freedom that requires both agent-causation and non-deterministic event-causation in the production of free action is assessed with an eye toward determining whether agent-causal accounts can accommodate the truth of judgments of moral obligation.

Event-causal libertarians maintain that an agent’s freely bringing about a choice is reducible to states and events involving him bringing about the choice. Agent-causal libertarians demur, arguing that free will requires that the agent be irreducibly causally involved. Derk Pereboom and Meghan Griffith have defended agent-causal libertarianism on this score, arguing that since on event-causal libertarianism an agent’s contribution to his choice is exhausted by the causal role of states and events involving him, and since these states and events leave (...) it open which decision he will make, he does not settle which decision occurs, and thus “disappears.” My aim is to explain why this argument fails. In particular, I demonstrate that event-causal libertarians can dismantle the argument by enriching the reductive base in their analysis of free will to include a state that plays the functional role of the self-determining agent and with which the agent is identified.

A crucial question for libertarians about free will and moral responsibility concerns how their accounts secure more control than compatibilism. This problem is particularly exasperating for event-causal libertarianism, as it seems that the only difference between these accounts and compatibilism is that the former require indeterminism. But how can indeterminism, a mere negative condition, enhance control? This worry has led many to conclude that the only viable form of libertarianism is agent-causal libertarianism. In this paper I show that this conclusion (...) is premature. I explain how event-causal libertarianism secures more control than compatibilism by offering a novel argument for incompatibilism. Part of the reason my solution has gone unnoticed is that it is often mistakenly assumed that an agent's control is wholly exhausted by the agent's powers and abilities. I argue, however, that control is constituted not just by what we have the ability to do, but also by what we have the opportunity to do. And it is by furnishing agents with new opportunities that event-causal libertarianism secures enhanced control. In order to defend this claim, I provide an analysis of opportunities and construct a novel incompatibilist argument to show that the opportunity to do otherwise is incompatible with determinism.

This paper responds to three critical essays on my book, The Significance of Free Will(Oxford, 1996) by Randolph Clarke, Istiyaque Haji and Alfred Mele (which essays appear in this issue and an earlier issue of this journal). This response first explains crucial features of the theory of free will of the book, including the notion of ultimate responsibility.The paper then answers objections of Haji and Mele that the occurrence of undetermined choices would be matters of luck or chance, and so (...) could not be responsible actions. It then responds to concerns of Clarke that indeterminism provides no greater degree of control for defenders of incompatibilist free will and to concerns Clarke has about the notions of "effort" and "willing" in the book. Finally, the paper addresses objections of Haji concerning Frankfurt type-examples and the relation of moral responsibility to the power to act otherwise, and it addresses a concern of Mele's about why we should want a free will that is incompatible with determinism.

In previous work, I have claimed that the Frankfurt-style counterexamples to the Principle of Alternative Possibilities work even in a world in which the actual sequence proceeds in a manner congenial to the libertarian. In “Libertarian Freedom and the Avoidability of Decisions,” Widerker criticizes this claim. Here I cast some doubt upon the criticism. Widerker’s critique depends on the falsity of a view held by Molina (and others) about the possibility of non-deterministic grounds for “would-conditionals.” Apart from this point, there (...) are plausible versions of libertarianism which avoid the thrust of Widerker’s criticism.

Event-causal libertarianism concerning free will faces two challenging problems of control. Indeterminism so diminishes control that it is incompatible with an indeterministically caused act's being free. Since event-causal libertarianism's metaphysical or agency commitments are no richer than those of its best compatibilist rivals, how does event-causal libertarianism secure for libertarian free agents more control than these rivals? I argue that the two problems are inextricably associated in that whether event-causal libertarianism can deliver enhanced control depends upon a solution to problem (...) , but there are formidable hurdles in the way of reaching this solution.

In a recent article, Meghan Griffith (American Philosophical Quarterly 47:43–56, 2010) argues that agent-causal libertarian theories are immune to the problem of luck but that event-causal theories succumb to this problem. In making her case against the event-causal theories, she focuses on Robert Kane’s event-causal theory. I provide a brief account of the central elements of Kane’s theory and I explain Griffith’s critique of it. I argue that Griffith’s criticisms fail. In doing so, I note some important respects in which (...) Kane’s view is unclear and I suggest a plausible way of reading Kane that makes his theory immune to Griffith’s objections. (shrink)
