In this paper I intend to raise a problem for so-called Frankfurt examples. I begin by describing the examples and what they are used for. Then I describe the problem.

The Blockage Argument is designed to improve upon Harry Frankfurt’s famous argument against the Principle of Alternative Possibilities by removing the counterfactual intervener altogether. If the argument worked, then it would prove in a way that Frankfurt’s argument does not that moral responsibility does not require any alternative possibilities whatsoever, not even the weakest “flicker of freedom”. Some philosophers have rejected the Blockage Argument solely on the basis of their intuition that the inability to do otherwise is incompatible with moral (...) responsibility. I will argue, however, that it is not merely the inability to do otherwise by itself but rather the inability to do otherwise in combination with the absence of a counterfactual intervener that is incompatible with moral responsibility. If I cannot do otherwise and it is not because of a counterfactual intervener, then it must be the case that I am being forced to choose and therefore act as I do, in which case I cannot be morally responsible for this action. Because the Blockage Argument fails, and because it was really the only way to establish that moral responsibility does not require any alternative possibilities whatsoever, it follows that moral responsibility does indeed require at least one alternative possibility in any given situation. But it turns out that this conclusion does not tip the balance in favor of incompatibilism over compatibilism. It would have if blockage and determinism were equivalent. But they are not. Unlike blockage, determinism is compatible with certain counterfactuals that compatibilists traditionally believed the ability to do otherwise reduces to. So even though moral responsibility is incompatible with blockage, it does not necessarily follow that moral responsibility is incompatible with determinism. (shrink)

The aim of this paper is to present a version of the principle of alternate possibilities which is not susceptible to the Frankfurt-style counter-example. I argue that PAP does not need to be endorsed as a necessary condition for moral responsibility and, in fact, presenting PAP as a sufficient condition maintains its usefulness as a maxim for moral accountability whilst avoiding Frankfurt-style counter-examples. In addition, I provide a further sufficient condition for moral responsibility – the twin world condition – and (...) argue that this provides a means of justifying why the protagonist in Frankfurt-style scenarios is still felt to be morally responsible. I conclude with the claim that neither the amended PAP nor the twin world condition is necessary for the ascription of moral responsibility; rather, what is necessary is simply that one of these conditions is satisfied.

This is a defense of John Stuart Mill’s proof of the principle of utility in the fourth chapter of his Utilitarianism. The proof is notorious as a fallacious attempt by a prominent philosopher, who ought not to have made the elementary mistakes he is supposed to have made. This book shows that he did not. The aim is not to glorify utilitarianism, in a full sweep, as the best normative ethical theory, or even to vindicate, on a more specific level, (...) Mill’s universalistic ethical hedonism as the best form of utilitarianism. The book is concerned only with Mill’s utilitarianism, and primarily with his proof of the principle of utility. The purpose is to show that Mill proceeds intelligibly and systematically in pursuing a well-defined project in the fourth chapter of Utilitarianism, and that he successfully defends what he sets out to establish in his proof of the principle of utility.

Frankfurt style examples (FSEs) have played an important role in the development of metaphysical accounts of moral agency. The legitimacy of this approach often requires that FSEs be metaphysically possible. I argue that, given our current knowledge of the nature of decision-making, we have no grounds to accept the metaphysical possibility of many standard FSEs involving a device that can be triggered to bring about a predetermined decision.

Frankfurt cases are purported counterexamples to the Principle of Alternative Possibilities, which implies that we are not morally responsible for unavoidable actions. A major permutation of the counterexample strategy features buffered alternatives; this permutation is designed to overcome an influential defense of the Principle of Alternative Possibilities. Here we defend the buffering strategy against two recent objections, both of which stress the timing of an agent’s decision. We argue that attributions of moral responsibility aren’t time-sensitive in the way the objectors (...) suppose. We then turn to the crucial question of when an action is relevantly avoidable—when, in the parlance of the literature, an alternative possibility is robust. We call attention to two plausible tests for robustness that merit further consideration, showing that the agents in buffered Frankfurt cases don’t pass these tests, despite being morally responsible for their actions.

The Principle that freedom is necessary for moral responsibility has received a variety of explications, but few philosophers have doubted that in some plausible sense it is true. However, two philosophers have recently challenged it using very different but equally ingenious arguments. J.F.M. Hunter has provided the more obviously direct attack in arguing that considerations of freedom as such are in no way relevant to assessments of moral responsibility. Harry Frankfurt has directed his fire at the version of the freedom (...) principle which says that a person is morally responsible for what he has done only if he could have done otherwise. Both Frankfurt and Hunter point out the significance of their arguments for the determinism/moral responsibility debate: if there is no freedom requirement for moral responsibility, then even if determinism threatens freedom, it does not follow that determinism threatens moral responsibility.

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)

In 1969 harry frankfurt attacked the principle of alternate possibilities, I.E., The principle that one is morally responsible for what one has done only if one could have done otherwise. The first two parts of this paper offer a supplement to and clarification of that principle; the third part defends the supplemented version of it against three frankfurt arguments; and the fourth comments on a recent discussion of it by michael zimmerman.

The standard argument for the incompatibility of determinism and moral responsibility employs the following two premises:A person is morally responsible for what he has done only if he could have done otherwise:A person could have done otherwise only if his action was not causally determined.While premise two has been the focus of an enormous amount of controversy, premise one until recently has remained virtually unchallenged. However, since Harry Frankfurt’s provocative paper in 1969, premise one, which he dubbed the principle of (...) alternate possibilities, has begun to attract its share of the debate. Frankfurt argued that PAP is false and that its falsity undermines the position of those who assert the incompatibility of determinism and moral responsibility. Two previous papers I wrote were devoted in part to showing that Frankfurt’s argument is ineffective; one of those papers also argued that, while PAP is indeed false as it stands, if it is appropriately supplemented, it can continue to serve its traditional role in the determinism-responsibility debate.

One response to the Frankfurtian attack on the Principle of Alternate Possibilities is to advert to the observation that the agent’s actual action (or the particular event resulting from that action) is numerically distinct from the corresponding action (or the resultant event) he would have generated in the relevant counterfactual scenario. Since this response is based on taking actions and events to be fragile, I shall call it the fragilist account of alternative possibilities. This paper addresses an anti-fragilist argument delivered (...) by John Martin Fischer. I contend that, on close examination, Fischer’s counterargument does not undermine the fragilist account.

The traditional debate between compatibilists and incompatibilists was based on the assumption that if determinism deprives us of free will and moral responsibility, it does so by making it true that we can never do other than what we actually do. All parties to the debate took for granted the truth of a claim now widely known as "the principle of alternate possibilities": someone is morally responsible only if he could have done otherwise. In a famous paper, Harry Frankfurt argued (...) that the principle of alternate possibilities is false. I argue that Frankfurt's argument rests on a modal fallacy. (shrink)

From an indeterminist's perspective, I support and defined the following argument for deontic incompatibilism: If determinism is true, then no one ever can do otherwise than he does. If no one ever can do otherwise than he does, then nothing anyone does is ever right, wrong, or obligatory. Therefore, if determinism is true, then nothing anyone does is ever right, wrong, or obligatory. ;They sense of 'can' I use in this argument is what I call "the power-'can' of ordinary language." (...) The power-'can' has two time indexes; one applies to the power itself, the other to the relevant doing. I argue that the power-'can' is a sense of 'can' with which the "ought implies can" principle holds true. ;I review and respond to various accounts of 'can' proposed by compatibilists Bruce Aune, Keith Lehrer, David Lewis, G. E. Moore and others. Elsewhere I discuss writings by Peter van Inwagen and J. L. Austin. ;To support , I utilize, argue for, and show the advantages of the Temporal Physical Possibility Requirements: If an agent, S, can at time T do A at time T$\sp\prime$, then S's doing A at $T\sp\prime$ is jointly possible with the conjunction of the state of the world at T and the laws of nature. When arguing for these requirements, I focus on how most people use the power-'can' and how they would use it in various situations. I present and respond to objections to my arguments. Most of the objections are based on certain strong forms of contextualism. ;I argue for and defend my premises against various objections. One objection is based on a form of utilitarianism advocated by Fred Feldman. Other objections are based on an example by Harry Frankfurt concerning moral responsibility. ;Two arguments against are presented and I respond. They are developed from a suggestion by John Martin Fischer that people would continue making deontic claims if a consortium of scientists were to find strong evidence of determinism. (shrink)

This paper aims to challenge the view that the sign present in many Frankfurt-style scenarios is insufficiently robust to constitute evidence for the possibility of an alternate decision, and therefore inadequate as a means of determining moral responsibility. I have amended Frankfurt’s original scenario, so as to allow Jones, as well as Black, the opportunity to monitor his (Jones’s) own inclination towards a particular decision (the sign). Different outcome possibilities are presented, to the effect that Jones’s awareness of his own (...) inclinations leads to the conclusion that the sign must be either (a) a prior determinate of the decision about to be made, (b) prior and indeterminate (therefore allowing for a contra-inclination decision to be made), or (c) constitutive of a decision that Jones has made but is not yet aware of. In effect, this means that, prior to the intervention of Black, Jones must have decided to do otherwise or could have so decided. Either way, although Frankfurt’s conclusion, that Jones could not have done other than he did, is upheld, the idea that he could not have decided otherwise must be rejected, and with it the view that the sign is nothing more than a flicker of freedom insufficient for assigning morally responsibility.

In this paper, we motivate, propose and defend the following two conditions as individually sufficient and disjunctively necessary for moral responsibility: PODMA —originally proposed by Coren, Acta Analytica, 33, 145–159,, now cast as sufficient rather than necessary—and the TWC*, which amends versions presented by Young, 961–969, 2016; Philosophia, 45, 1365–1380, 2017). We explain why there is a need for new necessary and sufficient conditions, how these build on and improve existing ideas, particularly in relation to Frankfurt-style counterexamples and the continuing (...) discussion on their effectiveness, and why PODMA and the TWC* are good candidates. Finally, we defend the proposal against anticipated objections in order to clarify why we think these individually sufficient and disjunctively necessary conditions are plausible and able to inform the ongoing debate on the role of alternate possibilities in the ascription of moral responsibility.
