A compelling requirement on normative theories is that they should be satisfiable, that is, in every possible choice situation with a finite number of alternatives, there should be at least one performable act such that, if one were to perform that act, one would comply with the theory. In this paper, I argue that, given some standard assumptions about free will and counterfactuals, Objective Act Consequentialism violates this requirement.

In this chapter we explain what the no-difference challenge is, focusing in particular on act consequentialism. We talk about how different theories of causation affect the no-difference challenge; how the challenge shows up in real-world cases including voting, global labour injustice, global poverty, and climate change; and we work through a number of the solutions to the challenge that have been offered, arguing that many fail to actually meet it. We defend and extend one solution that does, and present a (...) further solution of our own. (shrink)

Act‐consequentialism is best construed as a criterion of rightness, not a decision procedure. Act‐consequentialism recommends that our procedure for making moral decisions employs rules very like the ones endorsed by rule‐consequentialism. However, the chapter highlights the remaining significant differences between act‐consequentialism and rule‐consequentialism over prohibitions, and discusses the extreme demandingness of act‐consequentialist duties to aid.

Dual-ranking act-consequentialism (DRAC) is a rather peculiar version of act-consequentialism. Unlike more traditional forms of act-consequentialism, DRAC doesn’t take the deontic status of an action to be a function of some evaluative ranking of outcomes. Rather, it takes the deontic status of an action to be a function of some non-evaluative ranking that is in turn a function of two auxiliary rankings that are evaluative. I argue that DRAC is promising in that it can accommodate certain features of commonsense morality (...) that no single-ranking version of act-consequentialism can: supererogation, agent-centered options, and the self-other asymmetry. I also defend DRAC against three objections: (1) that its dual-ranking structure is ad hoc, (2) that it denies (putatively implausibly) that it is always permissible to make self-sacrifices that don’t make things worse for others, and (3) that it violates certain axioms of expected utility theory, viz., transitivity and independence.

According to Act Consequentialism, an act is right if and only if its outcome is not worse than the outcome of any alternative to that act. This view, however, leads to deontic paradoxes if the alternatives to an act are all other acts that can be done in the situation. A typical response is to only apply this rightness criterion to maximally specific acts and to take the alternatives to a maximally specific act to be the other maximally specific acts (...) that can be done in the situation. (This view can then be supplanted by a separate account for the rightness of acts that are not maximally specific.) This paper defends a rival view, Binary Act Consequentialism, where, for any voluntary act, that act is right if and only if its outcome is not worse than the outcome of not doing that act. Binary Act Consequentialism, which dates back to Jeremy Bentham, has few supporters. A number of seemingly powerful objections have been considered fatal. In this paper, I rebut these objections and put forward a positive argument for the view. (shrink)

A theory is agent neutral if it gives every agent the same set of aims and agent relative otherwise. Most philosophers take act-consequentialism to be agent-neutral, but I argue that at the heart of consequentialism is the idea that all acts are morally permissible in virtue of their propensity to promote value and that, given this, it is possible to have a theory that is both agent-relative and act-consequentialist. Furthermore, I demonstrate that agent-relative act-consequentialism can avoid the counterintuitive implications associated (...) with utilitarianism while maintaining the compelling idea that it is never wrong to bring about the best outcome. (shrink)

Consequentialist theories determine rightness solely based on real or expected consequences. Although such theories are popular, they often have difficulty with generalizing intuitions, which demand concern for questions like “What if everybody did that?” Rule consequentialism attempts to incorporate these intuitions by shifting the locus of evaluation from the consequences of acts to those of rules. However, detailed rule-consequentialist theories seem ad hoc or arbitrary compared to act consequentialist ones. We claim that generalizing can be better incorporated into consequentialism by (...) keeping the locus of evaluation on acts but adjusting the decision theory behind act selection. Specifically, we should adjust which types of dependencies the theory takes to be decision-relevant. Using this strategy, we formulate a new theory, generalized act consequentialism, which we argue is more compelling than rule consequentialism both in modeling the actual reasoning of generalizers and in delivering correct verdicts.

In the first two volumes of On What Matters, Derek Parfit argues that three major normative theories – Kantianism, Contractualism and Rule Consequentialism – are, in their most defensible forms, compatible, and can be reconciled in what he calls ‘Triple Theory’. This has led many to assume that Parfit does not believe that Act Consequentialism is a defensible form of Consequentialism. We draw on correspondence with Parfit to show that this assumption is incorrect. We then consider Parfit's efforts, in the (...) third volume of On What Matters, to narrow the differences between Act Consequentialism and the triple theory, in part by treating impartial rationality as an external rival to morality, in much the same way that egoism is an external rival to morality. We argue that Parfit's attempts to bridge the gap between Act Consequentialism and Triple Theory meet with only limited success. (shrink)

I present the mismatch problem for Act Consequentialism, and I critically evaluate some popular solutions before offering my own solution to a specific version of the problem. The mismatch problem arises for Act Consequentialism when a group could have done better, but no individual in the group had an alternative with a better outcome. In such cases, the theory delivers mismatched verdicts: it condemns what the group does, but it cannot condemn any of the individual acts. In the first chapter (...) of the dissertation, I explain exactly how this problem works. In the next four chapters, I identify a variety of cases that give rise to the mismatch problem, and I explain why the most popular strategies for modifying Act Consequentialism do not get around it. In the final chapter, I introduce a novel taxonomy of problem cases, and I introduce a 'cautious' version of Act Consequentialism that doesn't encounter the mismatch problem for a certain class of case.

This is Chapter 5 of my Commonsense Consequentialism: Wherein Morality Meets Rationality. In this chapter, I argue that those who wish to accommodate typical instances of supererogation and agent-centered options must deny that moral reasons are morally overriding and accept both that the reason that agents have to promote their own self-interest is a non-moral reason and that this reason can, and sometimes does, prevent the moral reason that they have to sacrifice their self-interest so as to do more to (...) promote the interests of others from generating a moral requirement. Furthermore, I argue that given that an act’s deontic status of both moral and non-moral reasons, the consequentialist must adopt dual-ranking act-consequentialism. I then defend dual-ranking act-consequentialism against a number of objections. (shrink)

Maximizing act consequentialism holds that actions are morally permissible if and only if they maximize the value of consequences—if and only if, that is, no alternative action in the given choice situation has more valuable consequences.[i] It is subject to two main objections. One is that it fails to recognize that morality imposes certain constraints on how we may promote value. Maximizing act consequentialism fails to recognize, I shall argue, that the ends do not always justify the means. Actions with (...) maximally valuable consequences are not always permissible. The second main objection to maximizing act consequentialism is that it mistakenly holds that morality requires us to maximize value. Morality, I shall argue, only requires that we satisfice (promote sufficiently) value, and thus leaves us a greater range of options than maximizing act consequentialism recognizes. (shrink)

Act consequentialism states that an act is right if and only if the expected value of its outcome is at least as great as the expected value of any other act’s outcome. Two objections to this view are as follows. The first is that act consequentialism cannot account for our normative ambivalence in cases where agents perform the right act out of bad motives. The second is that act consequentialism is silent on questions of character: questions like ‘What are the (...) right motives to have?’ and ‘What kind of person ought I be?’. These objections have been taken to motivate a move to global consequentialism, on which acts are not the only subjects of normative assessment. Motives and decision-procedures are also judged right or wrong by direct reference to their consequences. In this paper, I argue that these objections fail to motivate the move from act to global consequentialism. (shrink)

A book chapter (about 9,000 words, plus references) presenting an act-consequentialist approach to the ethics of climate change. It begins with an overview of act consequentialism, including a description of the view’s principle of rightness (an act is right if and only if it maximizes the good) and a conception of the good focusing on the well-being of sentient creatures and rejecting temporal discounting. Objections to act consequentialism, and replies, are also considered. Next, the chapter briefly suggests that act consequentialism (...) could reasonably be regarded as the default moral theory of climate change, in the sense that a broadly act-consequentialist framework often seems implicit in both scholarly and casual discussions of the ethics of climate change. The remainder of the chapter explores three possible responses to the threat of climate change: having fewer children to reduce the number of people emitting greenhouse gases; taxing greenhouse-gas (GHG) emissions (commonly called a “carbon tax”) to discourage GHG-emitting behavior; and reducing poverty to lessen personal, familial, and community vulnerability to the harms of climate change.

A variety of eating and purchasing practices, in particular vegetarianism, are often motivated via an appeal to their expected good consequences. Lurking in the background, however, is the question: can I really hope to make a difference via my purchases in a social world as complex and wasteful as our own? I review the evidence as it stands and conclude that there are good reasons to suspect that one probably does not make a difference directly via one's purchases. That said, (...) there may be some related, though less direct, reasons to be vegetarian. (shrink)

Kant considers eudaimonism as his main opponent and he assumes that his ethics is the only viable alternative to eudaimonism. He does not explicitly address theories differing from both eudaimonism and from his own. I argue that whilst Kant and Act-Consequentialists advocate different normative principles, their positions share the important abstract feature that they establish what is to be done from a rational principle and not based on what is in the self-interest of the respective agent, as Kant thinks eudaimonism (...) does. Act-Consequentialism is thus closer to Kant’s ethics than is often assumed. I will demonstrate and vindicate this point with a new interpretation of the Fact of Reason. This reading also establishes that the notion of a Fact of Reason is less contentious than many of Kant’s critics believe. We should not expect that the Fact establishes Kantianism. Instead, the Fact is only supposed to count against a specific competing view of morality, namely, eudaimonism. Act-Consequentialists can accept the Fact as well. (shrink)

Coordination games show that all individuals can do what is right according to act‐consequentialism, even if they do not bring about the best outcome as a group. This creates two problems for act‐consequentialism. First, it cannot accommodate the intuition that there is some moral failure in these cases. Second, its formulation as a criterion of rightness conflicts with the underlying act‐consequentialist concern that the best outcome is brought about. The collectivist view solves these problems by holding that any (...) group of two or more individual agents, and only individual agents, is a collective agent who itself can act rightly or wrongly. When such a collective agent does what is wrong, there is a moral failure. When all collective agents do what is right, the best outcome is brought about. In this paper, I defend the collectivist view against the No Act Objection, according to which the doings of many so called disunified collectives are not acts. (shrink)

A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, even when it would be impersonally better for others to bear these costs.

The standard form of act-consequentialism requires us to perform the action with the best consequences; it allows choice between moral options only on those rare occasions when several actions produce equally good results. This paper argues for moral options and thus against act-consequentialism. The argument turns on the insight that some valuable things cannot exist unless our moral system allows options. One such thing is the opportunity for individuals to enact plans for their life from among alternatives. Because planning one’s (...) life has value, and because it requires moral options, a world governed by a moral system that admits of options is better than one governed by act-consequentialism. The paper argues that these facts entail that morality admits of a significant number of moral options; act-consequentialism is false. (shrink)

In the 1960’s, Lars Bergström and Hector-Neri Castañeda noticed a problem with alternative acts and consequentialism. The source of the problem is that some performable acts are versions of other performable acts and the versions need not have the same consequences as the originals. Therefore, if all performable acts are among the agent’s alternatives, act consequentialism yields deontic paradoxes. A standard response is to restrict the application of act consequentialism to certain relevant alternative sets. Many proposals are based on some (...) variation of maximalism, that is, the view that act consequentialism should only be applied to maximally specific acts. In this paper, I argue that maximalism cannot yield the right prescriptions in some cases where one can either (i) form at once the intention to do an immediate act and form at a later time the intention to do a succeeding act or (ii) form at once the intention to do both acts and where the consequences of (i) and (ii) differ in value. Maximalism also violates normative invariance, that is, the condition that if an act is performable in a situation, then the normative status of the act does not depend on what acts are performed in the situation. Instead of maximalism, I propose that the relevant alternatives should be the exhaustive combinations of acts the agent can jointly perform without performing any other act in the situation. In this way, one avoids the problem of act versions without violating normative invariance. Another advantage is that one can adequately differentiate between possibilities like (i) and (ii).

Maximizing act consequentialism holds that actions are morally permissible if and only if they maximize the value of consequences—if and only if, that is, no alternative action in the given choice situation has more valuable consequences.1 It is subject to two main objections. One is that it fails to recognize that morality imposes certain constraints on how we may promote value. Maximizing act consequentialism fails to recognize, I shall argue, that the ends do not always justify the means. Actions with (...) maximally valuable consequences are not always permissible. The second main objection to maximizing act consequentialism is that it mistakenly holds that morality requires us to maximize value. Morality, I shall argue, only requires that we satisfice (promote sufficiently) value, and thus leaves us a greater range of options than maximizing act consequentialism recognizes. The issues discussed are, of course, highly complex, and space limitations prevent me from addressing them fully. Thus, the argument presented should be understood merely as the outline of an argument. (shrink)

As an indirect ethical theory, rule consequentialism first evaluates moral codes in terms of how good the consequences of their general adoption are and then individual actions in terms of whether or not the optimific code authorises them. There are three well-known and powerful objections to rule consequentialism’s indirect structure: the ideal world objection, the rule worship objection, and the incoherence objection. These objections are all based on cases in which following the optimific code has suboptimal consequences in the real (...) world. After outlining the traditional objections and the cases used to support them, this paper first constructs a new hybrid version of consequentialism that combines elements of both act and rule consequentialism. It then argues that this novel view has sufficient resources for responding to the previous traditional objections to pure rule consequentialism. (shrink)

This paper examines recent attempts to defend Rule-Consequentialism against a traditional objection. That objection takes the form of a dilemma, that either Rule-Consequentialism collapses into Act-Consequentialism or it is incoherent. Attempts to avoid this dilemma based on the idea that using RC has better results than using AC are rejected on the grounds that they conflate the ideas of a criterion of rightness and a decision procedure. Other strategies, Brad Hooker's prominent amongst them, involving the thought that RC need contain (...) no overarching concern to maximize the good are acknowledged to avoid the original dilemma, but lead to further problems of motivating and justifying RC in the absence of such a concern. The paper argues that Hooker's attempt to deal with these problems by using a 'Reflective Equilibrium plus method is unsuccessful. (shrink)

Consequentialist theories that directly assess multiple focal points face an important objection: that one right option may conflict with another. Robert Adams raises an instance of this objection regarding the possibility that the right act conflicts with the right motives. Whereas only partial responses have previously been given, assuming particular views of the relation between motives and acts, an exhaustive treatment is in order. Either motives psychologically determine acts, or they do not – and I defend direct consequentialism on each (...) assumption. Crucially, if motives determine acts, this may be compatible with the ability to act otherwise, but there remains a defense for consequentialism even on these assumptions. What clears consequentialism of conflict is not necessarily that the apparently right act is unavailable, but rather that its outcome is suboptimal once we account for necessary motives. Even if the agent remains free to perform the act, the act costs too much. (shrink)

Its relentless pursuit of the good provides act-consequentialism with one sort of intuitive ethical rationale. But more indirect forms of consequentialism promise more intuitive normative implications, for instance the evil of even beneficent murders. I favor a middle way which combines the intuitive rationale of act-consequentialism and the intuitive normative implications of the best indirect forms. Multiple-Act Consequentialism or ‘MAC’ requires direct consequentialist evaluation of the options of group agents. It holds that one should only defect from a group act (...) with good consequences if one can achieve better consequences by the defecting act alone than the entire group act achieves, and that when different beneficent group acts of which one is part specify roles which conflict, one should follow the role in the group act with better consequences. This paper develops MAC as a solution to the Trolley Problem. Section 1 concerns the relative advantages of direct and indirect consequentialisms. Section 2 develops MAC by a focus on competing conceptions of group agency. Section 3 applies MAC to the Trolley Problem. (shrink)

Most arguments in support of act utilitarianism are elaborations of one of two basic strategies. One is the consequentialist strategy. This strategy relies on the consequentialist premise that an act is right if and only if it produces the best possible consequences and the welfarist premise that the value of a state of affairs is entirely determined by its overall amount of well-being. The other strategy is based on the idea of treating individuals respectfully and resolving conflicts among individuals in (...) whatever way best conforms to that idea. Although both of these strategies can be used to argue for the principle of act utilitarianism, they are significantly different from each other, and these differences cause them to have different strengths and weaknesses. It emerges that which argumentative strategy is chosen by a proponent of act utilitarianism has a large impact on which virtues her view has and which objections it is vulnerable to. (shrink)

This paper explores what a Rule Consequentialist of Brad Hooker's sort can and should say about normative rea- sons for action. I claim that they can provide a theory of reasons, but that doing so requires distinguishing dif- ferent roles of rules in the ideal code. Some rules in the ideal code specify reasons, while others perform differ- ent functions. The paper also discusses a choice that Rule Consequentialists face about how exactly to specify rea- sons. It ends by comparing (...) the theory of reasons offered by Rule Consequentialism with the theory offered by Act Consequentialism, noting that Rule Consequentialism seems better able to explain moral constraints. (shrink)

Act-consequentialism (C) is self-effacing for an agent iff that agent’s not accepting C would produce the best outcome. The question of whether C is self-effacing is important for evaluating C. Some hold that if C is self-effacing that would be a mark against it (Williams 1973: 134); however, the claim that C is self-effacing is also used to defend C against certain objections (Parfit 1984: Ch. 1, Railton 1984). -/- In this paper I will show that one argument suggested by (...) Parfit and Railton fails to establish that C is self-effacing for individuals. However, a slightly different argument may show that C is self-effacing for groups. This raises the intriguing possibility that it might be right for an individual, but not for a group of which they are a member, to accept a moral theory. This possibility, odd though it seems, might be helpful to consequentialists. (shrink)

Consequentialist theories often neglect reasons for action. They offer theories of the rightness or the goodness of actions, or of virtue, but they typically do not include theories of reasons. However, consequentialists can give plausible accounts of reasons. This chapter examines some different ways in which such accounts might be developed, focusing on Act Consequentialism and Rule Consequentialism and on the relationship between reasons and rightness. It notes that adding claims about reasons to consequentialist theories may introduce a welcome kind (...) of complexity, and in doing so may help to make consequentialist approaches to ethics more appealing. For example, it may help consequentialists to explain the ideas of moral constraints and moral options. (shrink)

An influential objection to act-consequentialism holds that the theory is unduly demanding. This paper is an attempt to approach this critique of act-consequentialism – the Overdemandingness Objection – from a different, so far undiscussed, angle. First, the paper argues that the most convincing form of the Objection claims that consequentialism is overdemanding because it requires us, with decisive force, to do things that, intuitively, we do not have decisive reason to perform. Second, in order to investigate the existence of the (...) intuition, the paper reports empirical evidence of how people see the normative significance of consequentialist requirements.. In a scenario study that recruited a sample which is representative of the German population in key characteristics, it finds that there is no widely shared intuition as to the excessive demandingness of consequentialist requirements, although people do find higher demands less reasonable. This is true irrespective of people’s level of formal education despite the fact that lower levels of formal education are associated with an increased likelihood of having intuitions that are consistent with the Objection. Apart from contributing in this way to the debate concerning the Overdemandingness Objection, the paper also more directly speaks to the basic discussion concerning the status and role of intuitions in moral philosophy. It discusses methodological questions relevant to the role of intuitions and ends with proposing an improved methodology to investigate intuitions that connects them to emotions in a particular way and also proposes a role for virtue.

What are appropriate criteria for assessing a theory of morality? In Ideal Code, Real World, Brad Hooker begins by answering this question, and then argues for a rule-consequentialist theory. According to rule-consequentialism, acts should be assessed morally in terms of impartially justified rules, and rules are impartially justified if and only if the expected overall value of their general internalization is at least as great as for any alternative rules. In the course of developing his rule-consequentialism, Hooker discusses impartiality, well-being, (...) fairness, equality, the question of how the 'general internalization' of rules is to be interpreted by rule-consequentialism, and the main objections to rule-consequentialism. He also discusses the social contract theory of morality, act-consequentialism, and the question of which moral prohibitions and which duties to help others rule-consequentialism endorses. The last part of the book considers the implications of rule-consequentialism for some current controversies in practical ethics. (shrink)

Many contemporary act consequentialists define facts about what we should do in terms of facts about what we should prefer. They claim that we should perform an action if and only if we should prefer its outcome to the outcome of any available alternative. Some of these theorists claim they can accommodate deontic constraints, such as a constraint against killing the innocent. I argue that they can’t. If there’s a constraint against killing, then when we can prevent five killings only (...) by killing one, we shouldn’t kill—but we should prefer the outcome where we do. (shrink)

I explore the debate about whether consequentialist theories can adequately accommodate the moral force of promissory obligation. I outline a straightforward act consequentialist account grounded in the value of satisfying expectations, and raise and assess three objections to this account: that it counterintuitively predicts that certain promises should be broken when commonsense morality insists that they should be kept, that the account is circular, and Michael Cholbi’s argument that this account problematically implies that promise-making is frequently obligatory. I then discuss (...) alternative act consequentialist accounts, including Philip Pettit’s suggestion that promise-keeping is an intrinsic good and Michael Smith’s agent-relative account. I outline Brad Hooker’s rule consequentialist account of promissory obligation and raise a challenge for it. I conclude that appeals to intuitions about cases will not settle the dispute, and that consequentialists and their critics must instead engage in substantive debate about the nature and stringency of promissory obligation.

Act-consequentialism is usually taken to be the view that we ought to perform the act that will have the best consequences. But this definition ignores the possibility of various non-maximizing forms of act-consequentialism, e.g. satisficing theories that tell us to perform the act whose consequences will be good enough. What seems crucial to act-consequentialism is not that we ought to maximize value but that the normative status of alternative actions depends solely on the values of their outcomes. The purpose of (...) this paper is to spell out this dependency claim and argue that it should be seen as the denning feature of act-consequentialism. In particular, I will defend the definition against certain objections that purport to show that the definition is too wide and too narrow. (shrink)

It is often said that there are three great traditions of normative ethics: consequentialism, deontology and virtue ethics. Each is based around a compelling intuition about the nature of ethics: that what is ultimately important is that we produce the best possible outcome, that ethics is a system of rules which govern our behaviour, and that ethics is about living a life that instantiates the virtues, such as honesty, compassion and loyalty. This essay is about how best to interpret consequentialism. (...) I show that if we take consequentialism beyond the assessment of acts, using a consequentialist criterion to assess decision making, motivation, and character, then the resulting theory can also capture many of the intuitions about systems of moral rules and excellences of character that lead people to deontology and virtue ethics. I begin by considering the argument that consequentialism is self-defeating because its adoption would produce bad outcomes. I take up the response offered by the classical utilitarians: when properly construed, consequentialism does not require us to make our decisions by a form of naïve calculation, or to be motivated purely by universal benevolence. Instead it requires us to use the decision procedure that will produce the best outcome and to have the motives that lead to the best outcome. I take this idea as my starting point, and spend the thesis developing it and considering its implications. I demonstrate that neither act-consequentialism nor rule-consequentialism has the resources to adequately assess decision making and motivation. I therefore turn to the idea of global consequentialism, which assesses everything in terms of its consequences. I then spend the greater part of the essay exploring how best to set up such a theory and how best to apply it to decision making and motivation. I overcome some important objections to the approach, and conclude by showing how the resulting approach to consequentialism helps to bridge the divide between the three traditions. (shrink)

This paper argues that objective consequentialism is incompatible with the rationales of ‘ “ought” implies “can” ’ – with the considerations, that is, that explain or justify this principle. Objective consequentialism is the moral doctrine that an act is right if and only if there is no alternative with a better outcome, and wrong otherwise. An act is obligatory if and only if it is wrong not to perform it. According to ‘ “ought” implies “can” ’, a person is morally (...) obligated to φ only if the person can φ. The rationales of ‘ “ought” implies “can” ’ include considerations related to intuitive plausibility, action-guidance, blameworthiness and fairness, and the nature of practical reasons. (shrink)

The thesis of this paper is that consequentialism does not work as a comprehensive theory of right action. This paper does not offer a typical refutation, in that I do not claim that consequentialism is self-contradictory. One can with perfect consistency claim that the good is prior to the right and that the right consists in maximizing the good. What I claim, however, is that it is senseless to make such a claim. In particular, I attempt to show that the (...) notion of what course of action maximizes the good has no content within a consequentialist framework. Since the problem that I identify rests with maximization, this refutation does not cut across the act/rule distinction. If rule consequentialism holds that there are occasions on which one should follow a rule rather than violate the rule in an optimific way, then it is not maximizing and my arguments do not apply; if not, then it collapses into act consequentialism. I have nothing to say about nonmaximizing forms of consequentialism.1 This refutation does, however, cut across the direct/indirect distinction.2 It makes no difference whether we take consequentialism as offering a principle of decision, or a standard of right. Presumably the former would be parasitic upon the latter for its legitimacy. (shrink)

Does the decision to relax by taking a drive rather than by taking a walk cause harm? In particular, do the additional carbon emissions caused by such a decision make anyone worse off? Recently several philosophers have argued that the answer is no, and on this basis have gone on to claim that act-consequentialism cannot provide a moral reason for individuals to voluntarily reduce their emissions. The reasoning typically consists of two steps. First, the effect of individual emissions on the (...) weather is miniscule: the planet’s meteorological system is so large, and the size of individual emissions so tiny, that whatever impact an individual emission has on the weather must be vanishingly small. Second, vanishingly small impacts aren’t morally relevant because no one could possibly tell the difference between such an impact occurring and it not occurring. In this paper, we show why both steps are mistaken, and hence why act-consequentialism implies that each of us has an individual obligation to do what we can to stop damaging the climate, including by refraining from, or perhaps by purchasing offsets against, our own individual luxury carbon emissions.

This paper offers some refinements to a particular objection to act consequentialism, the “causal impotence” objection. According to proponents of the objection, when we find circumstances in which severe, unnecessary harms result entirely from voluntary acts, it seems as if we should be able to indict at least one act among those acts, but act consequentialism appears to lack the resources to offer this indictment. Our aim is to show is that the most promising response on behalf of act consequentialism, (...) the threshold argument, cannot offer a fully general prescription about what to do in cases of collective action. (shrink)

Rule consequentialism (RC) is the view that it is right for A to do F in C if and only if A's doing F in C is in accordance with the the set of rules which, if accepted by all, would have consequences which are better than any alternative set of rules (i.e., the ideal code). I defend RC from two related objections. The first objection claims that RC requires obedience to the ideal code even if doing so has disastrous (...) results. Though some rule consequentialists embrace a disaster-clause which permits agents to disregard some of the rules in the ideal code as a necessary means of avoiding disasters, they have not adequately explained how this clause works. I offer such an explanation and show how it fits naturally with the rest of RC. The second disaster objection asserts that even if RC can legitimately invoke a disaster-clause, it lacks principled grounds from distinguishing disasters from non-disasters. In response, I explore Hooker's suggestion that “disaster” is vague. I contend that every plausible ethical theory must invoke something similar to a disaster clause. So if “disaster” is vague, then every plausible ethical theory faces a difficulty with it. As a result, this vagueness is not a reason to prefer other theories to RC. However, I argue, contra Hooker, that the sense of “disaster” relevant to RC is not vague, and RC does indeed have principled grounds to distinguish disasters from nondisasters. (shrink)

Many consequentialists argue that you ought to do your part in collective action problems like climate change mitigation and ending factory farming because (i) all such problems are triggering cases, in which there is a threshold number of people such that the outcome will be worse if at least that many people act in a given way than if fewer do, and (ii) doing your part in a triggering case maximises expected value. I show that both (i) and (ii) are (...) false: Some triggering cases cannot be solved by appeal to expected value, since they involve infinities, and some collective action problems are not triggering cases, since they involve parity. However, I argue that consequentialism can still generally prohibit failure to do your part in those collective action problems where we believe that so acting would be impermissible. (shrink)

Moral wrongness comes in degrees. On a consequentialist view of ethics, the wrongness of an act should depend, I argue, in part on how much worse the act's consequences are compared with those of its alternatives and in part on how difficult it is to perform the alternatives with better consequences. I extend act consequentialism to take this into account, and I defend three conditions on consequentialist theories. The first is consequentialist dominance, which says that, if an act has better (...) consequences than some alternative act, then it is not more wrong than the alternative act. The second is consequentialist supervenience, which says that, if two acts have equally good consequences in a situation, then they have the same deontic status in the situation. And the third is consequentialist continuity, which says that, for every act and for any difference in wrongness δ greater than zero, there is an arbitrarily small improvement of the consequences of the act which would, other things being equal, not change the wrongness of that act or any alternative by more than δ. I defend a proposal that satisfies these conditions. (shrink)

Arguments for moral consequentialism often appeal to an alleged structural similarity between consequentialist reasoning in ethics and rational decision-making in everyday life. Ordinary rational decision-making is seen as a paradigmatic case of goal-oriented, teleological decision-making, since it allegedly aims at maximizing the goal of preference satisfaction. This chapter describes and discusses a neglected type of preference change, “predictable preference accommodation.” This phenomenon leads to a number of critical cases in which the rationality of a particular choice does not depend on (...) features of the outcome of the chosen act. On the basis of these cases, it is argued that consequentialists cannot point to everyday decision-making as an uncontroversial example of consequentialist reasoning. On the contrary, it is suggested that an adequate account of rationality in prudential choice may need a Kantian notion of respect. (shrink)
