Almost thirty years ago, in an attempt to undermine what he termed "the principle of alternate possibilities" (the thesis that people are morally responsible for what they have done only if they could have done otherwise), Harry Frankfurt offered an ingenious thought-experiment that has played a major role in subsequent work on moral responsibility and free will. Several philosophers, including David Widerker and Robert Kane, argued recently that this thought-experiment and others like it are fundamentally flawed. This paper develops a (...) new Frankfurt-style example that is immune to their objections. [Reprinted in Laura Waddell Ekstrom, ed., Agency and Responsibility: Essays on the Metaphysics of Freedom (Westview Press, 2001), pp. 241-54; and in John Martin Fischer, ed., Free Will, Vol. III (Routledge, 2005), pp. 330-42.].

The principle of alternate possibilities (PAP), making the ability to do otherwise a necessary condition for moral responsibility, is supposed by Harry Frankfurt, John Fischer, and others to succumb to a peculiar kind of counterexample. The paper reviews the main problems with the counterexample that have surfaced over the years, and shows how most can be addressed within the terms of the current debate. But one problem seems ineliminable: because Frankfurt''s example relies on a counterfactual intervener to preclude alternatives to (...) the person''s action, it is not possible for it to preclude all alternatives (intervention that is contingent upon a trigger cannot bring it about that the trigger never occurred). This makes it possible for the determined PAPist to maintain that some pre-intervention deviation is always available to ground moral responsibility. In reply, the critic of PAP can examine all the candidate deviations and argue their irrelevance to moral responsibility (a daunting prospect); or the critic can dispense with counterfactual intervention altogether. The paper pursues the second of these strategies, developing three examples of noncounterfactual intervention in which (i) the agent has no alternatives (and a fortiori no morally relevant alternatives), yet (ii) there is just as much reason to think that the agent is morally responsible as there was in Frankfurt''s original example. The new counterexamples do suffer from one liability, but this is insufficient in the end to repair PAP''s conceptual connection between moral responsibility and alternate possibilities. (shrink)

David Widerker has forcefully argued that a libertarian is on firm ground in believing that the principle of alternative possibilities (PAP) is true. Eleonore Stump has argued that not all libertarians need accept PAP, and that its acceptance is not required for a rejection of compatibilism.This paper is a defense of Widerker against Stump. I argue that it is not at all clear that Stump’s view of freedom is libertarian in nature, and that she has not provided a good reason (...) for thinking that a libertarian can abandon PAP. (shrink)
