According to some scholars, while sets of greenhouse gases emissions generate harms deriving from climate change, which can be mitigated through collective actions, individual emissions and mitigation activities seem to be causally insufficient to cause harms. If so, single individuals are neither responsible for climate harms, nor they have mitigation duties. If this view were true, there would be collective responsibility for climate harms without individual responsibility and collective mitigation duties without individual duties: this is puzzling. This paper explores a (...) way to solve this puzzle. First, it will be argued that individual emissions, though not proper and full-fledged causes, causally contribute to raise the probability of climate harms. As a consequence, individuals are in fact responsible for their expected contributions to climate harms – this is contributive responsibility for likely outcomes. Second, it will be argued that people have responsibility also for the possible impacts of their individual emissions on climate harms. People can plausibly be regarded as individually responsible for the possible outcomes of their actions in close possible alternative worlds – this is robust responsibility. Non-causal individual responsibility for climate harms is plausible, and the puzzle may be solved. (shrink)

This paper tries to explain why racial profiling involves a serious injustice and to do so in a way that avoids the problems of existing philosophical accounts. An initially plausible view maintains that racial profiling is pro tanto wrong in and of itself by violating a constraint on fair treatment that is generally violated by acts of statistical discrimination based on ascribed characteristics. However, consideration of other cases involving statistical discrimination suggests that violating a constraint of this kind may not (...) be an especially serious wrong in and of itself. To fully capture the significant wrong that occurs when racial profiling is targeted at black Americans or other similarly situated groups, it is argued that we should appeal to the idea that this basic injustice is exacerbated when it forms part of a larger pattern of similar actions that collectively realize a state of cumulative injustice.

Do consumers’ ordinary actions of purchasing certain goods make them complicit in global labour injustice? To establish that they do, two things much be shown. First, it must be established that they are not more than complicit, for example that they are not the principal perpetrators. Second, it must be established that they meet the conditions for complicity on a plausible account. I argue that Kutz’s account faces an objection that makes Lepora and Goodin’s better suited, and defend the idea (...) that consumers are complicit in at least two of the ways distinguished by the latter. In the final section of the paper, I consider whether consumers’ responsibility for complicity in global labour injustice is likely to be as strong as responsibility from another source, namely benefiting from that injustice.

Our thesis is that there is no moral requirement to refrain from emitting reasonable amounts of greenhouse gases solely in order to enjoy oneself. Joyriding in a gas guzzler provides our paradigm example. We first distinguish this claim that there is no moral requirement to refrain from joyguzzling from other more radical claims. We then review several different proposed objections to our view. These include: the claim that joyguzzling exemplifies a vice, causes or contributes to harm, has negative expected value, (...) exceeds our fair share of global emissions, and undermines political duties. We show why none of these objections succeeds and conclude that no good reason has yet been proposed that shows why joyguzzling violates a moral requirement. (shrink)

Many people argue that we should practice conscientious consumption. Faced with goods from gravely flawed production processes, such as wood from clear-cut rainforests or electronics containing conflict minerals, they argue that we should enact personal policies to routinely shun tainted goods and select pure goods. However, consumers typically should be relatively uncertain about which flaws in global supply chains are grave and the connection of purchases to those grave flaws. The threat of significant uncertainty makes conscientious consumption appear to be (...) no better, or even worse, than an overlooked option. This overlooked option is consumption with relinquishment: disregarding each product’s possible connections with upstream grave flaws and using the time, money, and energy saved in this way to address grave flaws directly.

Some of the most pressing contemporary social problems result from the amalgamation of a mass of actions that are not intentionally coordinated. Although these essentially aggregative harms are foreseeable, it is unclear what moral duties individuals have with regards to them. This paper offers a new analysis of these problems and uses a nonideal contractualist approach to argue in favour of two kinds of duties for individuals. Collectivization duties that require individuals to act responsively with a view to ensuring that (...) there are effective governance agents that reliably, fairly, and efficiently prevent these outcomes in the long-term and duties of restraint that require individuals to avoid action of a kind that is likely to come together with other actions to cause serious EAH in the immediate future when restraint with regards to actions of this kind could help prevent the outcome from occurring.

Many morally significant outcomes can be brought about only if several individuals contribute to them. However, individual contributions to collective outcomes often fail to have morally significant effects on their own. Some have concluded from this that it is permissible to do nothing. What I call ‘the problem of insignificant hands’ is the challenge of determining whether and when people are obligated to contribute. For this to be the case, I argue, the prospect of helping to bring about the outcome (...) has to be good enough. Furthermore, the individual must be in a position to increase the probability of its being brought about to an appropriate extent. Finally, I argue that when too few are willing to contribute, people may have a duty to increase their number. Thus, someone can be obligated to contribute or to get others to contribute. This prospect account is consistent with Kantianism, contractualism and rule consequentialism but inconsistent with act consequentialism. (shrink)

When consumers choose to abstain from purchasing meat, they face some uncertainty about whether their decisions will have an impact on the number of animals raised and killed. Consequentialists have argued that this uncertainty should not dissuade consumers from a vegetarian diet because the “expected” impact, or average impact, will be predictable. Recently, however, critics have argued that the expected marginal impact of a consumer change is likely to be much smaller or more radically unpredictable than previously thought. This objection (...) to the consequentialist case for vegetarianism is known as the “causal inefficacy” (or “causal impotence”) objection. In this paper, we argue that the inefficacy objection fails. First, we summarize the contours of the objection and the standard “expected impact” response to it. Second, we examine and rebut two contemporary attempts (by Mark Budolfson and Ted Warfield) to defeat the expected impact reply through alleged demonstrations of the inefficacy of abstaining from meat consumption. Third, we argue that there are good reasons to believe that single individual consumers—not just consumers in aggregate—really do make a positive difference when they choose to abstain from meat consumption. Our case rests on three economic observations: (i) animal producers operate in a highly competitive environment, (ii) complex supply chains efficiently communicate some information about product demand, and (iii) consumers of plant-based meat alternatives have positive consumption spillover effects on other consumers.

Do I cause global warming, climate change and their related harms when I go for a leisure drive with my gas-guzzling car? The current verdict seems to be that I do not; the emissions produced by my drive are much too insignificant to make a difference for the occurrence of global warming and its related harms. I argue that our verdict on this issue depends on what we mean by ‘causation’. If we for instance assume a simple counterfactual analysis of (...) causation according to which ‘C causes E’ means ‘if C had not occurred, E would not have occurred’, we must conclude that a single drive does not cause global warming. However, this analysis of causation is well-known for giving counterintuitive results in some important cases. If we instead adopt Lewis’s analysis of causation, it turns out that it is indeterminate whether I cause global warming when I go for a single drive. Still, in contexts where we seek to control or understand global warming, there is a pressure to adopt a more fragile view of this event. When we adopt such a view, it turns out that a single drive does cause global warming. This means that we cannot like Sinnott-Armstrong and Kingston and Sinnott-Armstrong reject the idea that I should refrain from going for a leisure drive simply because such a drive does not cause global warming.

The mismatch problem for consequentialism arises whenever the theory delivers mismatched verdicts between a group act and the individual acts that compose it. A natural thought is that moving to expected utility versions of consequentialism will solve this problem. I explain why the move to expected utility is not successful.

Moral problems such as climate change and global poverty result from widespread human action, and hence, are unaffected by changes in any individual's behavior—for instance, the harms of climate change will obtain whether I drive my car or not. This problem of causal impotence seems potentially devastating for consequentialists, but more easily addressed by deontologists. The deontologist can argue that (e.g.) even if our acts will have no effect on climate change, our using fossil fuels makes us complicit in, and (...) hence, blameworthy for, these wrongs. We argue that, despite initial appearances, appeals to complicity do not extricate deontologists from this problem. When our actions do not make a difference, we cannot be held responsible for being complicit in wrongs such as climate change and global poverty. As a result, we conclude that the problem of causal impotence is as vexing for deontologists as it is for consequentialists. (shrink)

In some cases, a group of people can bring about a morally bad outcome despite each person’s individual act making no difference with respect to bringing that outcome about. Since each person’s act makes no difference, it seems the effects of the act cannot provide a reason not to perform it. This is problematic, because if each person acts in accordance with their reasons, each will presumably perform the act—and thus, the bad outcome will be brought about. Recently, Julia Nefsky (...) has argued that this problem is solved by rejecting the assumption that if an act makes no difference with respect to an outcome, then the act cannot do anything non-superfluous toward bringing that outcome about. Nefsky suggests that, even if an act makes no difference, the act may nevertheless help: it may make a non-superfluous causal contribution. If this is right, it means that the potential effects of an act may give us a reason to perform the act, even if the act wouldn’t make a difference. In this paper, I offer some reasons to be wary of Nefsky’s approach. I first argue that her account generates problematic results in a certain range of cases, and thus that we may have no reason to help in any case. I then argue that, even if we do sometimes have a reason to act when it seems we cannot make a difference, this reason cannot be the one that Nefsky identifies. (shrink)

This paper argues that individuals in many high-income countries typically have moral reasons to limit their beef consumption and consume plant-based protein instead, given the negative effects of beef production and consumption. Beef production is a significant source of agricultural greenhouse gas emissions and other environmental impacts, high levels of beef consumption are associated with health risks, and some cattle production systems raise animal welfare concerns. These negative effects matter, from a variety of moral perspectives, and give us collective moral (...) reasons to reduce beef production and consumption. But, as some ethicists have argued, we cannot draw a straight line from the ethics of production to the ethics of consumption: even if a production system is morally impermissible, this does not mean that any given individual has moral reasons to stop consuming the products of that system, given how miniscule one individual’s contributions are. This paper considers how to connect those dots. We consider three distinct lines of argument in support of the conclusion that individuals have moral reasons to limit their beef consumption and shift to plant-based protein, and we consider objections to each argument. This argument applies to individuals in high beef-consuming and high greenhouse gas-emitting high-income countries, though we make this argument with a specific focus on the United States. (shrink)

It is sometimes—but not always—permissible to let others do wrong. This paper is about why that is so.

Global warming is a very complex collective harm. While various models have been proposed to assign moral responsibility in such cases, global warming presents an additional problem. The complexity of the climate system gives rise to ineliminable indeterminacy, which makes it impossible to determine the extent to which any particular emissions contribute to this collective harm. This indeterminacy poses an obstacle to assigning moral responsibility to individuals. To overcome this obstacle, I propose adopting a supervaluationist approach. This approach has several (...) benefits. Among other things, it supplies a framework for assigning moral responsibility that handles indeterminacy that commonly arises when dealing with complex, global collective-harm scenarios. (shrink)

I argue that agents can have duties to cooperate with one another if this increases their combined efficiency and/or efficacy in addressing ongoing collective moral problems. I call these duties cooperative duties of efficiency and efficacy. I focus particularly on collective agents and how agents ought to reason and act in the face of global moral problems. After setting out my account, I argue that a subset of cooperative duties of efficiency and efficacy of collective agents are duties of justice (...) in virtue of the roles these agents have taken up.

In this paper, I offer a prolegomenon to the philosophy of harm reduction. I begin with an overview of the philosophical literature on both harm and harm reduction, and a brief summary of harm reduction scholarship outside of philosophy in order to make the case that philosophers have something to contribute to understanding harm reduction, and moreover that engagement with harm reduction would improve philosophical scholarship. I then proceed to survey and assess the nascent and still modest philosophy of harm (...) reduction literature that has begun to emerge. I pay particular attention to two Canadian philosophers who have called for the expansion of harm reduction beyond the realm of so-called “vice”. Finally, I sketch some of the most interesting and important philosophical issues that I think the philosophy of harm reduction must grapple with going forward. (shrink)

Several philosophers deny that an individual person’s emissions of greenhouse gas do any harm; I call these “individual denialists.” I argue that each individual’s emissions may do harm, and that they certainly do expected harm. I respond to the denialists’ arguments.

Many philosophers argue that individuals have duties to do their fair shares of the demands of achieving important common ends. But what happens when some individuals fail to do their fair shares?...

Both individuals and governments around the world have willingly sacrificed a great deal to meet the collective action problem posed by Covid-19. This has provided some commentators with newfound hope about the possibility that we will be able to solve what is arguably the greatest collective action problem of all time: global climate change. In this paper we argue that this is overly optimistic. We defend two main claims. First, these two collective action problems are so different that the actions (...) that individuals have taken to try to solve the problem posed by Covid-19 unfortunately provide little indication that we will be able to solve the problem posed by climate change. Second, the actions that states have taken in response to Covid-19 might—if anything—even be evidence that they will continue to fail to cooperate towards a solution to the climate crisis. (shrink)

Obgleich die Ausdrücke ‚moralische Pflicht’ und ‚moralische Verantwortung’ auf den ersten Blick nahezu austauschbar scheinen, ist in einigen Debatten dennoch fast ausschließlich von moralischer Verantwortung die Rede. Dies gilt insbesondere für die moralische Beurteilung von individuellen Handlungen in kollektiven Kontexten. Hier scheint die Rede von einer ‚kollektiven Verantwortung‘ besonders attraktiv zu sein. In diesem Aufsatz setze ich mich diesem Trend entgegen und argumentiere dafür, dem Pflichtbegriff in kollektiven Kontexten gegenüber dem Begriff der Verantwortung den Vorrang zu geben. Mein Fokus liegt (...) hierbei auf einer bestimmten Art von Handlungen in kollektiven Kontexten, nämlich auf Handlungen in sogenannten Aggregatkollektiven. Von Aggregatkollektiven verursachte Schäden sind häufig kumulative Schäden, bei denen die Handlungen der Mitglieder eines Aggregatkollektivs einzeln betrachtet keinen merklichen Unterschied für das Auftreten des Schadens machen. Die Rede von Verantwortung legt ein Haftbarkeitsmodell moralischer Verantwortung nahe, welches sich in Bezug auf Handlungen in Aggregatkollektiven als problematisch erweist. Ich zeige, dass Kants Konzeption unvollkommener Pflichten eine vielversprechende Alternative zu dem kausal gefärbten Begriff der moralischen Verantwortung darstellt. Durch den Spielraum, den unvollkommene Pflichten Akteuren lassen, bieten sie eine ähnliche Offenheit wie der Begriff der moralischen Verantwortung. Anders als die Zuschreibung von Verantwortung vermeidet die Rede von unvollkommenen Pflichten jedoch die in kollektiven Kontexten oft inadäquate und kontraproduktive Assoziation von Haftung und Schuld.

There are cases such as climate change where the cumulative effects of the actions of several agents lead to grave harm but where no individual agent can make a perceptible difference for the better or worse. According to Derek Parfit, dealing with such imperceptible difference cases requires substantial changes to the way we think about morality. InOn What Matters, Parfit builds on Kantian Ethics to address the problem of imperceptible differences, but the transformation that Kant's theory undergoes in his hands (...) is radical. I argue that Parfit's changes to Kant's theory are not only unnecessary but also detrimental to making sense of the ethical dimensions of action in collective contexts. Building on the notion of imperfect duties, I offer an alternative solution to the problem of imperceptible difference cases that remains closer to Kant's original theory and avoids the difficulties of Parfit's approach.

Though there have been productive interactions between moral philosophers and deontic logicians, there has also been a tradition of neglecting the insights that the fields can offer one another. The most sustained interactions between moral philosophers and deontic logicians have notbeen systematic but instead have been scattered across a number of distinct and often unrelated topics. This chapter primarily focuses on three topics. First, we discuss the “actualism/possibilism” debate which, very roughly, concerns the relevance of what one will do at (...) some future time to what one ought to do at present (§2). This topic is also used to introduce various modal deontic logics. Second we discuss the particularism debate which, very roughly, concerns whether there can be any systematic general theory of what we ought to do (§3). This topic is also used to introduce various non-modal deontic logics. Third, we discuss collective action problems which concern the connection between the obligations of individuals and the behavior and obligations of groups of individuals (§4).This topic is also used to discuss formal systems that allow us to study the relationship between individuals and groups. The chapter also contains a general discussion of the relation between ethical theory and deontic logic (§1) and a brief consideration of other miscellaneous topics (§5). (shrink)

From the 1992 Rio Earth Summit to the 2009 Copenhagen Climate Conference there was a concerted international effort to stop climate change. This book is about what climate change is, why we failed to stop it, and why it still matters what we do.

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)
