In the last few decades, the relevance of quantum mechanics to the free-will debate has been discussed at length, especially in relation to the prospects of libertarianism. Basing his interpretation on Anscombe’s seminal work, Putnam argued in 1979 that, given that quantum mechanical indeterminacy is holistic at the macrolevel—i.e., it is not traceable to atomistic events such as quantum jumps of single atoms—it can provide libertarians with the kind of freedom they seek. As shown in this article, however, Putnam ultimately (...) reached the conclusion—together with the other author of this article—that his argument was wrong due to problems with the way it appealed to the Uncertainty Principle.**.

A version of the principle of alternate possibilities claims that one is only blameworthy for actions which one was able to avoid. Much of the discussion about PAP concerns Frankfurt’s counterexamples to it. After fifty years of refined debates, progress might seem hopeless. Yet, we can make headway by asking: “what’s our reason for believing PAP?” The best answer is this: lacking eligible alternatives—alternatives whose cost is not too high to reasonably opt for—is a good excuse. Yet, this principle is (...) subject to straightforward counterexamples, unless it is given an epistemicised reading. And in this latter case, it does not support PAP. So, PAP is unsupported, at least for now. (shrink)

Some defenders of the principle of alternative possibilities (PAP) have responded to the challenge of Frankfurt-style counterexamples (FSCs) to PAP by arguing that there remains a flicker of freedom -- that is, an alternative possibility for action -- left to the agent in FSCs. I argue that the flicker of freedom strategy is unsuccessful. The strategy requires the supposition that doing an act-on-one''s-own is itself an action of sorts. I argue that either this supposition is confused and leads to counter-intuitive (...) results; or, if the supposition is acceptable, then it is possible to use it to construct a FSC in which there is no flicker of freedom at all. Either way, the flicker of freedom strategy is ineffective against FSCs. Since the flicker of freedom strategy is arguably the best defense of PAP, I conclude that FSCs are successful in showing that PAP is false. An agent can act with moral responsibility without having alternative possibilities available to her. (shrink)

The Direct Argument for the incompatibility of moral responsibility and determinism is designed to side-step complaints given by compatibilist critiques of the so-called Transfer Argument. I argue that while it represents an improvement over the Transfer Argument, it loses some of its plausibility when we reflect on some metalogical issues about normal modal modeling and the semantics of natural language. More specifically, the crucial principle on which the Direct Argument depends appears doubtful where context plays a role in evaluation of (...) normative claims. (shrink)

John Martin Fischer and Mark Ravizza (1998) advance an innovative form of compatibilism between free will and determinism. They characterize the relevant freedom as the control condition necessary...

In _The Philosophical Quarterly, 47 (1997), pp. 373-381, van Inwagen argues in a critical notice of my book _The Metaphysics of Free Will that the impression that Frankfurt-type examples show that moral responsibility need not require alternative possibilities results from insufficient analytical precision. He suggests various precise principles which imply that moral responsibility requires alternative possibilities. In reply, I seek to defend the conclusion I have drawn from Frankfurt-type examples: moral responsibility need not require alternative possibilities. I contend that van (...) Inwagen's principle the principle of possible prevention and the no-matter-what principle are invalid, and I suggest that their plausibility comes from thinking about a proper subset of the relevant cases.
