In a recent article, David Hunt has proposed a theological counterexample to the principle of alternative possibilities involving divine foreknowledge (G-scenario). Hunt claims that this example is immune to my criticism of regular Frankfurt-type counterexamples to that principle, as God’s foreknowing an agent’s act does not causally determine that act. Furthermore, he claims that the considerations which support the claim that the agent is morally responsible for his act in a Frankfurt-type scenario also hold in a G-scenario. In reply, Icontest Hunt’s symmetry claim and also raise a worry whether, given theological fatalism, the agent’s act in a G-scenario can be deemed a free act in the libertarian sense. Finally, I offer an independent argument why in a G-scenario the agent should not regarded morally blameworthy for his act.

This paper evaluates three recent attacks on what Harry Frankfurt has called the principle of alternate possibilities (PAP), i.e., the principle that if a person could not have done otherwise he is not morally responsible for what he has done. One critic of PAP argues that, if a person was drawn irresistibly to a drug yet was “altogether delighted with his condition”, he might well be morally responsible even though he could not have done otherwise. A second critic describes circumstances in which, if the agent had failed to perform a certain action, physical forces would have taken effect and caused him to perform that action. Such a person, he argues, may be morally responsible for what he has done even though he could not have done otherwise. I argue that both of the preceding counterexamples fail. The third argument against PAP shows, I maintain, that PAP is not acceptable as it stands; appropriately supplemented, however, it will continue to serve its traditional role in the compatibilist-incompatibilist debate.

In ‘Alternate Possibilities and Moral Responsibility,’ Harry Frankfurt introduces a scenario aimed at showing that the having of alternative possibilities is not required for moral responsibility. According to the Principle of Alternative Possibilities (PAP), an agent is morally responsible for her action only if she could have done otherwise; Frankfurt thinks his scenario shows that PAP is, in fact, false. Frankfurt thinks that the denial of PAP gives credence to compatibilism, the thesis that an agent could both be causally determined in all her actions and yet be morally responsible.1 Since its introduction, Frankfurt’s original ex-.

Frankfurt-style cases are widely taken to show that agents do not need alternative possibilities to be morally responsible for their actions. Many philosophers take these cases to constitute a powerful argument for compatibilism: if we do not need alternative possibilities for moral responsibility, it is hard to see what the attraction of indeterminism might be. I defend the claim that even though Frankfurt-style cases establish that agents can be responsible for their actions despite lacking alternatives, agents can only be responsible if they possess certain powers, and possession of these powers is - arguably - incompatible with determinism. Because this is the case, Frankfurt-style cases fail to advance the debate between compatibilism and incompatibilism.

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.

Discussions of the principle of alternative possibilities have largely ignored the limits of what Frankfurt-style counter-examples can show. Rather than challenging the coherence of the cases, I argue that even if they are taken to demonstrate the falsity of the principle, they cannot advance the compatibilist cause. For a forceful incompatibilist argument can be constructed from the Frankfurtian premise that agents in Frankfurtian circumstances would have done what they did even if they could have done something else. This 'counterfactual stability' meets the same fate under determinism as does the ability to do otherwise. Thus the cases are irrelevant to the compatibility debate.

Frankfurt-style examples aim to undermine the principle that moral responsibility requires the ability to do otherwise, which in turn requires the availability of alternate possibilities.1 They are thus considered a reason for refuting incompatibilism. One lesson drawn from Frankfurt-style examples is exemplified by the compatibilist account of Fischer and Ravizza.2 They accept the impact of Frankfurt-style cases and hold that the incompatibilist requirement of regulative control, which involves the agent’s ability to perform the action and her ability to perform the contrary action, must be dropped. In its stead, they propose the weaker requirement of guidance control, which only demands the agent’s causal control over the action for which she is to be held responsible.

In his classic paper, "The Principle of Alternate Possibilities," Harry Frankfurt presented counterexamples to the principle named in his title: A person is morally responsible for what he has done only if he could have done otherwise. He went on to argue that the falsity of the Principle of Alternate Possibilities (PAP) implied that the debate between the "compatibilists" and the "incompatibilists" (as regards determinism and the ability to do otherwise) did not have the significance that both parties had attributed to it - since moral responsibility could exist even if no one was able to do otherwise. I have argued that even if PAP is false, there are other principles that imply that moral responsibility entails the ability to do otherwise, and that these principles are immune to "Frankfurt-style" counterexamples. Frankfurt has attempted to show that my arguments for this conclusion fail. This paper is a rejoinder to that reply; I argue that he has failed to show this.

Harry Frankfurt has famously criticized the principle of alternate possibilities—the principle that an agent is morally responsible for performing some action only if able to have done otherwise than to perform it—on the grounds that it is possible for an agent to be morally responsible for performing an action that is inevitable for the agent when the reasons for which the agent lacks alternate possibilities are not the reasons for which the agent has acted. I argue that an incompatibilist about determinism and moral responsibility can safely ignore so-called “Frakfurt-style cases” and continue to argue for incompatibilism on the grounds that determinism rules out the ability to do otherwise. My argument relies on a simple—indeed, simplistic—weakening of the principle of alternate possibilities that is explicitly designed to be immune to Frankfurt-style criticism. This alternative to the principle of alternate possibilities is so simplistic that it will no doubt strike many readers as philosophically fallow. I argue that it is not. I argue that the addition of one highly plausible premise allows for the modified principle to be employed in an argument for incompatibilism that begins with the observation that determinism rules out the ability to do otherwise. On the merits of this argument I conclude that deterministic moral responsibility is impossible and that Frankfurt’s criticism of the principle of alternate possibilities—even if successful to that end—may be safely ignored.
