Consequentialism in Applied Ethics

It has recently been argued that a person’s moral judgments (about both their own and others’ actions) are constrained by the nature and extent of their relevant ignorance and, thus, that such judgments are determined in the first instance by the person’s epistemic circumstances. It has been argued, in other words, that the epistemic is logically prior to other normative (e.g., ethical, prudential, pecuniary) considerations in human decision-making, that these other normative considerations figure in decision-making only after (logically and temporally) (...) relevant ignorance has constrained the decision-maker’s menu of options. If this is right, then a person’s moral judgments in some set of circumstances should vary with their knowledge and ignorance of these circumstances. In this study, we test the hypothesis of the logical priority of the epistemic. We describe two experiments in which subjects’ knowledge and ignorance of relevant consequences were manipulated. In the second experiment, we also compared the effect of ignorance on moral judgments with that of personal force, a factor previously shown to influence moral judgments. We found broad empirical support for the armchair arguments that epistemic considerations are logically prior to normative considerations. (shrink)

Rights-based approaches and consequentialist approaches to ethics are often seen as being diametrically opposed to one another. In one sense, they are. In another sense, however, they can be reconciled: a ‘global’ form of consequentialism might supply consequentialist foundations for a derivative morality that is non-consequentialist, and perhaps rights-based, in content. By way of case study to illustrate how this might work, I survey what a global consequentialist should think about a recent dispute between Jeff McMahan and Henry Shue on (...) the morality and laws of war.

In the context of a global pandemic, there is good health-based reason for governments to impose various social distancing measures. However, such measures also cause economic and other harms to people at low risk from the virus. In this paper, I examine how to make such trade-offs in a way that is respectfully justifiable to their losers. I argue that existing proposals like using standard QALY (quality-adjusted life-year) valuations or WELLBYs (wellbeing-adjusted life-years) as the currency for trade-offs do not allow (...) such justification, because they give weight to utilities that are irrelevant in a life-and-death context. Drawing on work on restricted aggregation in ethics, I articulate an alternative framework for balancing claims arising from prospects of different kinds of harm and benefit, and show how it can be applied to reasoning about trade-offs in a pandemic context.

Suppose that, for reasons of animal welfare, it would be better if everyone stopped eating chicken. Does it follow that you should stop eating chicken? Proponents of the “inefficacy objection” argue that, due to the scale and complexity of markets, the expected effects of your chicken purchases are negligible. So the expected effects of eating chicken do not make it wrong. -/- We argue that this objection does not succeed, in two steps. First, empirical data about chicken production tells us (...) that the expected effects of consuming *many* chickens are not negligible. Second, this implies that the expected effect of consuming one chicken is ordinarily not negligible. *Parity* between your purchase and other counterfactual purchases and *uncertainty* about others’ consumption behavior each tend to pull the expected effect of a single purchase toward the average large scale effect. While some purchases do have negligible expected effects, many do not. (shrink)

Sam Harris (2010) argues that, given our neurology, we can experience well-being, and that seeking to maximize this state lets us distinguish the good from the bad. He takes our ability to compare degrees of well-being as his starting point, but I think that the analysis can be pushed further, since there is a (non-religious) reason why well-being is desirable, namely the finite life of an individual organism. It is because death is a constant possibility that things can be assessed (...) as “for” or “against” one (Champagne 2011a; Smith 2000). Such an account lets us objectively adjudicate moral questions, as Harris desires. However, by anchoring itself in the mortal body as a whole and not just the brain, such an account dampens the claim that neuroscience would have all the answers. Moreover, it pivots on an affirmation of one’s life that can seem mysterious by regular scientific standards. This chapter thus explains why the trade-off is worthwhile. (shrink)

Should we make significant sacrifices to ever-so-slightly lower the chance of extremely bad outcomes, or to ever-so-slightly raise the chance of extremely good outcomes? *Fanaticism* says yes: for every bad outcome, there is a tiny chance of extreme disaster that is even worse, and for every good outcome, there is a tiny chance of an enormous good that is even better. I consider two related recent arguments for Fanaticism: Beckstead and Thomas's argument from *strange dependence on space and time*, and (...) Wilkinson's *Indology* argument. While both arguments are instructive, neither is persuasive. In fact, the general principles that underwrite the arguments (a *separability* principle in the first case, and a *reflection* principle in the second) are *inconsistent* with Fanaticism. In both cases, though, it is possible to rehabilitate arguments for Fanaticism based on restricted versions of those principles. The situation is unstable: plausible general principles tell *against* Fanaticism, but restrictions of those same principles (with strengthened auxiliary assumptions) *support* Fanaticism. All of the consistent views that emerge are very strange. (shrink)

This article demonstrates a priori cosmopolitan values of restraint and harm limitation exist to establish a cosmopolitan “no-harm” duty in warfare, predating utilitarianism and permeating modern international humanitarian law. In doing so, the author exposes the atemporal and ahistorical nature of utilitarianism which introduces chaos and brutality into the international legal system. Part 2 conceptualises the duty as derived from the “no-harm” principle under international environmental law. Part 3 frames the discussion within legal pluralism and cosmopolitan ethics, arguing that divergent (...) legal jurisdictions without an international authority necessitates a “public international sphere” to mediate differences leading to strong value-commitment norm-creation. One such norm is the “no-harm” duty in warfare. Part 4 traces the duty to the Stoics, Christianity, Islam, Judaism, African traditional culture, Hinduism, and Confucianism. Parts 5 and 6 explain how the duty manifests in principles of distinction and proportionality under international humanitarian law. (shrink)

Effective Altruism is a rapidly growing and influential contemporary philosophical movement committed to updating utilitarianism in both theory and practice. The movement focuses on identifying urgent but neglected causes and inspiring supererogatory giving to meet the need. It also tries to build a broader coalition by adopting a more ecumenical approach to ethics which recognizes a wide range of values and moral constraints. These interesting developments distinguish Effective Altruism from the utilitarianism of the past in ways that invite cooperation and (...) warrant a fresh look from Thomists. Nonetheless Effective Altruism’s fundamentally consequentialist and aggregative model for ethics precludes more foundational agreement with Thomistic ethics in ways that limit the extent of practical cooperation.

This chapter introduces several distinctions relevant to what is called the “discounting problem”, since the issue is how (future) costs and benefits are discounted to make them comparable in present terms. The author defends the claim that there are good reasons to adopt Ramsey-style discounting in the context of climate change: the Ramsey rule is robust, flexible, and well-understood. An important distinction involved in discounting—“descriptivism” and “prescriptivism”—is discussed. It is argued that, even if we adopt prescriptivism, and accept that this (...) means there is need for moral experts in parameter assignments, there is a significant issue. The type of moral expertise required for the discounting problem will not involve knowledge of moral theory—thus making moral philosophy unhelpful in terms of making particular parameter assignments, despite these being substantive moral judgments.

In this paper, I argue that Consequentialism represents a kind of ethical theory that is the most plausible to serve as a basis for a machine ethic. First, I outline the concept of an artificial moral agent and the essential properties of Consequentialism. Then, I present a scenario involving autonomous vehicles to illustrate how the features of Consequentialism inform agent action. Thirdly, an alternative Deontological approach will be evaluated and the problem of moral conflict discussed. Finally, two bottom-up approaches to (...) the development of machine ethics are presented and briefly challenged. (shrink)

Consequentialism is thought to be in significant conflict with animal rights theory because it does not regard activities such as confinement, killing, and exploitation as in principle morally wrong. Proponents of the “Logic of the Larder” argue that consequentialism results in an implausibly pro-exploitation stance, permitting us to eat farmed animals with positive well- being to ensure future such animals exist. Proponents of the “Logic of the Logger” argue that consequentialism results in an implausibly anti-conservationist stance, permitting us to exterminate (...) wild animals with negative well-being to ensure future such animals do not exist. We argue that this conflict is overstated. Once we have properly accounted for indirect effects, such as the role that our policies play in shaping moral attitudes and behavior and the importance of accepting policies that are robust against deviation, we can see that consequentialism may converge with animal rights theory significantly, even if not entirely.

Proponents of the utilitarian animal welfare argument (AWA) for veganism maintain that it is reasonable to expect that adopting a vegan diet will decrease animal suffering. In this paper I argue otherwise. I maintain that (i) there are plausible scenarios in which refraining from meat-consumption will not decrease animal suffering; (ii) the utilitarian AWA rests on a false dilemma; and (iii) there are no reasonable grounds for the expectation that adopting a vegan diet will decrease animal suffering. The paper is (...) divided into four sections. In the first, I set out the utilitarian AWA in its original form. I give some background and I distinguish it from other, related arguments. In the second, I discuss the causal impotence objection, a popular objection to the utilitarian AWA. I explain how the objection works by means of a conceptual distinction between consumers and producers. In the third, I explain how proponents of the utilitarian AWA respond to this objection. In particular, I set out in some detail what I call the expected utility response. In the fourth and final section, I use the three objections noted above to explain why I do not find this response convincing. (shrink)

Utility discounting in intertemporal economic modelling has been viewed as problematic, both for descriptive and normative reasons. However, positive utility discount rates can be defended normatively; in particular, it is rational for future utility to be discounted to take into account model-independent outcomes when decision-making under risk. The resultant values will tend to be smaller than descriptive rates under most probability assignments. This also allows us to address some objections that intertemporal considerations will be overdemanding. A principle for utility discount (...) rates is suggested which is rooted in probability discounting. Utility discounting is defended against objections from Parfit (1984) and Broome (2005); Broome (2012). A sample utility discount rate is estimated. [Open access]. (shrink)

The assumption that procuring more organs will save more lives has inspired increasingly forceful calls to increase organ procurement. This project, in contrast, directly questions the premise that more organ transplantation means more lives saved. Its argument begins with the fact that resources are limited and medical procedures have opportunity costs. Because many other lifesaving interventions are more cost‐effective than transplantation and compete with transplantation for a limited budget, spending on organ transplantation consumes resources that could have been used to (...) save a greater number of other lives. This argument has not yet been advanced in debates over expanded procurement and could buttress existing concerns about expanded procurement. To support this argument, I review existing empirical data on the cost‐effectiveness of transplantation and compare them to data on interventions for other illnesses. These data should motivate utilitarians and others whose primary goal is maximizing population‐wide health benefits to doubt the merits of expanding organ procurement. I then consider two major objections: one makes the case that transplant candidates have a special claim to medical resources, and the other challenges the use of cost‐effectiveness to set priorities. I argue that there is no reason to conclude that transplant candidates’ medical interests should receive special priority, and that giving some consideration to cost‐effectiveness in priority setting requires neither sweeping changes to overall health priorities nor the adoption of any specific, controversial metric for assessing cost‐effectiveness. Before searching for more organs, we should first ensure the provision of cost‐effective care. (shrink)

Health policy is only one part of social policy. Although spending administered by the health sector constitutes a sizeable fraction of total state spending in most countries, other sectors such as education and transportation also represent major portions of national budgets. Additionally, though health is one important aspect of economic and social activity, people pursue many other goals in their social and economic lives. Similarly, direct benefits—those that are immediate results of health policy choices—are only a small portion of the (...) overall impact of health policy. This chapter considers what weight health policy should give to its “spill-over effects,” namely non-health and indirect benefits. (shrink)

Effective altruists either believe they ought to be, or strive to be, doing the most good they can. Since they’re human, however, effective altruists are invariably fallible. In numerous situations, even the most committed EAs would fail to live up to the ideal they set for themselves. This fact raises a central question about how to understand effective altruism. How should one’s future prospective failures at doing the most good possible affect the current choices one makes as an effective altruist? (...) This question is important to answer not only because every effective altruist will face this question due to typical human akrasia, but also because how the question is answered will determine just how demanding effective altruism can be. I argue that no matter how effective altruists answer this question, they will have to take on some commitments seemingly antithetical to their movement. More precisely, I argue that effective altruism is subject to a dilemma. Effective altruists’, at times, implicit actualist assumptions (i) commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (ii) undermine effective altruists’ arguments against moral offsetting and giving to charities close to the heart. Yet, effective altruists’, at times, implicit possibilist assumptions (iii) also commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (iv) undermine typical responses to demandingness worries for the normative conception of effective altruism. I argue that the best way out of the dilemma is to accept hybridism, though even hybridism won’t preserve every commitment of effective altruism. (shrink)

Many philosophers, psychologists, and medical practitioners believe that killing is no worse than letting die on the basis of James Rachels's Bare-Difference Argument. I show that his argument is unsound. In particular, a premise of the argument is that his examples are as similar as is consistent with one being a case of killing and the other being a case of letting die. However, the subject who lets die has both the ability to kill and the ability to let die (...) while the subject who kills lacks the ability to let die. Modifying the latter example so that the killer has both abilities yields a pair of cases with morally different acts. The hypothesis that killing is worse than letting die is the best explanation of this difference. (shrink)

Utilitarianism has an apparent pedigree when it comes to animal welfare. It supports the view that animal welfare matters just as much as human welfare. And many utilitarians support and oppose various practices in line with more mainstream concern over animal welfare, such as that we should not kill animals for food or other uses, and that we ought not to torture animals for fun. This relationship has come under tension from many directions. The aim of this article is to (...) add further considerations in support of that tension. I suggest three ways in which utilitarianism comes significantly apart from mainstream concerns with animal welfare. First, utilitarianism opposes animal cruelty only when it offers an inefficient ratio of pleasure to pain; while this may be true of eating animal products, it is not obviously true of other abuses. Second, utilitarianism faces a familiar problem of the inefficacy of individual decisions; I consider a common response to this worry, and offer further concerns. Finally, the common utilitarian argument against animal cruelty ignores various pleasures that humans may get from the superior status that a structure supporting exploitation confers. (shrink)

Prof. Cohen and I answer six questions: (1) Why do we lock people up? (2) How can involuntary civil commitment be reconciled with people's constitutional right to liberty? (3) Why don't we treat homicide as a public health threat? (4) What is the difference between legal and medical approaches to mental illness? (5) Why is mental illness required for involuntary commitment? (6) Where are we in our efforts to understand the causes of mental illness?

This is the introduction to the Journal of Global Ethics symposium on Peter Singer's The Most Good You Can Do: How Effective Altruism is Changing Ideas About Living Ethically. It summarizes the main features of effective altruism in the context of Singer's work on the moral demands of global poverty and some recent criticisms of effective altruism. The symposium contains contributions by Anthony Skelton, Violetta Igneski, Tracy Isaacs and Peter Singer.

Why does American law allow the recreational use of some drugs, such as alcohol, tobacco, and caffeine, but not others, such as marijuana, cocaine, and heroin? The answer lies not simply in the harm the use of these drugs might cause, but in the perceived morality—or lack thereof—of their recreational use. Despite strong rhetoric from moral critics of recreational drug use, however, it is surprisingly difficult to discern the reasons they have for deeming the recreational use of (some) drugs morally (...) wrong. In this book, Rob Lovering lays out and dissects various arguments for the immorality of using marijuana, cocaine, heroin, and other drugs recreationally. He contends that, by and large, these arguments do not succeed. Lovering's book represents one of the first works to systematically present, analyze, and critique arguments for the moral wrongness of recreational drug use. Given this, as well as the popularity of the morality-based defense of the United States' drug laws, this book is an important and timely contribution to the debate on the recreational use of drugs.

Critics of carbon mitigation often appeal to what Jonathan Glover has called ‘the argument from no difference’: that is, ‘If I don’t do it, someone else will’. Yet even if this justifies continued high emissions by the industrialised countries, it cannot excuse business as usual. The North’s emissions might not harm the victims of climate change in the sense of making them worse off than they would otherwise be. Nevertheless, it receives benefits produced at the latter’s expense, with the result (...) that it has more than it deserves, and that victims will have less. This enrichment is unjust; unjustly enriched agents ought to make compensation. The best form of compensation is vigorous action against climate change. (shrink)

In this essay, I critically examine the ways in which the characters of Alias attempt to balance their impartial moral obligations (e.g. duties toward humanity) and their personal obligations (e.g. duties toward one's children). I specifically examine three areas of conflict: (1) choices between saving loved ones and maximizing consequences, (2) choices to maintain or sever relationships with characters who are vicious or immoral, and (3) choices to seek or not seek revenge on the behalf of loved ones. I conclude (...) that Sydney's and Jack's moral choices show that one can and should privilege loved ones to some extent, but that this privilege has limits. (shrink)

Narrowly understood, veganism is the practice of excluding all animal products from one’s diet, with the exception of human milk. More broadly, veganism is not only a food ethics, but it encompasses all other areas of life. As defined by the Vegan Society when it became an established charity in the UK in 1979, veganism is best understood as “a philosophy and way of living which seeks to exclude – as far as is possible and practicable – all forms of (...) exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment”. There are two main moral justifications for veganism, both of which rely on a common assumption: that sentience, i.e., the capacity to feel pleasure and pain, is the necessary and sufficient trait to be morally considerable. In what follows, I present these two justifications and a third one which, although less popular, captures some core intuitions among vegans. I then present a challenge faced by veganism and two arguments that reject it as discriminatory, and briefly conclude. (shrink)

As a moral foundation for vegetarianism and other consumer choices, act consequentialism can be appealing. When we justify our consumer and dietary choices this way, however, we face the problem that our individual actions rarely actually precipitate more just agricultural and economic practices. This threshold or individual impotence problem engaged by consequentialist vegetarians and their critics extends to morally motivated consumer decision-making more generally, anywhere a lag persists between individual moral actions taken and systemic moral progress made. Regan and others (...) press just this point against Singer's utilitarian basis for vegetarianism; recently Chartier criticizes act-consequentialist vegetarianism by identifying many factors weakening the connection between individual meat purchases and changes in animal production. While such factors are relevant to act-consequentialist moral reasoning, I argue, they need not defeat the act-consequentialist case for vegetarianism and consumer ethics. This is shown by offering a probabilistic account of the threshold issue and discussing the positive and negative role-modelling effects of our morally motivated dietary and consumer choices.

In this paper I argue that applied ethics is a phenomenon spontaneously emerged between the Sixties and the Seventies and resulting from interbreeding of theoretical discussion in ethics and public discourse of liberal-democratic societies. I contend that the phenomenon’s novelty is in a peculiar relationship it has helped in establishing between ethical theories and real-world issues, and besides that the true nature of applied ethics is that of deliberation, whose tool is the faculty of judgment, or casuistry, understood the Kantian (...) way.

In the past decade, three philosophers in particular have recently explored the relation between desert and intrinsic value. Fred Feldman argues that consequentialism need not give much weight – or indeed any weight at all – to the happiness of persons who undeservedly experience pleasure. He defends the claim that the intrinsic value of a state of affairs is determined by the “fit” between the amount of well-being that a person receives and the amount of well-being that the person deserves. (...) Shelly Kagan uses a similar claim to motivate the view that equality is not intrinsically valuable. Thomas Hurka argues that desert is a third-order value, which is a function of the relation between the second-order value of having a virtuous or vicious character and the first-order value of experiencing pleasure or pain. In this paper, we sketch a theory of desert as fittingness and defend a general account of the relation between desert, well-being, and intrinsic value. We then discuss various applications of our “geometry of desert,” including a solution to the problem of the Repugnant Conclusion. In so doing, we explain, revise, and extend many of these authors’ central ideas. (shrink)

An option range is a set of alternative actions available to an agent at a given time. I ask how a moral theory’s account of option ranges relates to its recommendations about deliberative procedure (DP) and criterion of rightness (CR). I apply this question to Act Consequentialism (AC), which tells us, at any time, to perform the action with the best consequences in our option range then. If anyone can employ this command as a DP, or assess (direct or indirect) (...) compliance with it as a CR, someone must be able to tell which actions fit this description. Since the denseness of possibilia entails that any option range is indefinitely large, no one can do this. So no one can know that any option has ever emerged from any range as the best option in that range. However we come to know that a given option is right, we never come to know it in AC’s way. It is often observed that AC cannot give us a DP. AC cannot give us a CR either, unless we are omniscient. So Act Consequentialism is useless. (shrink)
