The doctrine (or principle) of double effect is often invoked to explain the permissibility of an action that causes a serious harm, such as the death of a human being, as a side effect of promoting some good end. According to the principle of double effect, sometimes it is permissible to cause a harm as a side effect (or “double effect”) of bringing about a good result even though it would not be permissible to cause such a harm as a (...) means to bringing about the same good end. Does the principle of double effect play the important explanatory role that has been claimed for it? To consider this question, one must be careful to clarify just what the principle is supposed to explain. Three misinterpretations of the principle’s force or range of application are common. 1. To ensure that Double Effect is not misunderstood as principle issuing a blanket permission on causing any unintended harm that yields a benefit, applications must require that the agent seek to minimize the harm involved. 2. Since it is widely accepted that it is wrong to aim to produce harm to someone as an end, to rule this out is not part of double effect’s distinctive content. 3. Harms that were produced regretfully and only for the sake of producing a good end may be prohibited by double effect because they were brought about as part of the agent’s means to realizing the good end.

Recent empirical studies of philosophers by Eric Schwitzgebel and others have seriously called into question whether professional ethicists have any useful expertise with thought experiments, given that their intuitions appear to be no more reliable than those of lay subjects. Drawing on such results, sceptics like Edouard Machery argue that normative ethics as it is currently practiced is deeply problematic. In this paper, I present two main arguments in defense of the standard methodology of normative ethics. First, there is strong (...) reason to believe that expertise with thought experiments requires considering scenarios in their proper theoretical context and in parallel with other pertinent situations, so that we should not expect philosophers to be better than lay folk at responding to decontextualized cases. Second, skeptical views underestimate the epistemic benefits of the actual practices of post-processing initial verdicts both at individual and social levels. Contrary to a mythical conception of ‘the method of cases’, philosophers are frequently sensitive to the quality of intuitive evidence, reject and revise their verdicts on the basis of independently supported principles or interpersonal criticism, and defer to recognized specialists.

Chapter 1 of this book argued that moral philosophy should be based on seven principles of theory selection adapted from the sciences. Chapter 2 argued that these principles support basing normative moral philosophy on a particular problem of diachronic instrumental rationality: the ‘problem of possible future selves.’ Chapter 3 argued that a new moral principle, the Categorical-Instrumental Imperative, is the rational solution to this problem. Chapter 4 argued that the Categorical-Instrumental Imperative has three equivalent formulations akin to but superior to (...) Kant’s formulations of the Categorical Imperative. Chapter 5 argued that my principle’s three formulations make it rational to adopt a Moral Original Position to derive moral principles. The present chapter derives Four Principles of Fairness from the Moral Original Position--principles of coercion minimization, mutual assistance, fair negotiation, and virtue—and unifies them into a single principle of rightness: Rightness as Fairness. Finally, this chapter argues that Rightness as Fairness entails a novel approach to applied ethics called ‘principled fair negotiation’, illustrating how the theory provides a plausible new framework for addressing applied cases including lying, suicide, trolleys, torture, distribution of scarce resources, poverty, and the ethical treatment of animals.

This chapter suggests a scheme of reconstruction, which explains how scenarios, questions and arguments figure in thought experiments. It then develops a typology of ethical thought experiments according to their function, which can be epistemic, illustrative, rhetorical, heuristic or theory-internal. Epistemic functions of supporting or refuting ethical claims rely on metaethical assumptions, for example, an epistemological background of reflective equilibrium. In this context, thought experiments may involve intuitive as well as explicitly argued judgements; they can be used to generate moral (...) commitments, to explore consequences of moral theories, and to show inconsistencies within or between moral commitments and moral theory; but the results of thought experiments by themselves do not settle what is epistemically justified and may also be rejected. Finally, some prominent challenges are discussed: do unrealistic scenarios undermine epistemic thought experiments? Are ethical thought experiments misleading? Do they rely on weak analogies? Are there specifically moral objections to ethical thought experiments? (shrink)

Ex-ante deontology is an attempt to combine deontological constraints on doing or intending harm with the idea that one should act in everyone’s interest if possible. I argue that ex-ante deontology has serious problems in cases where multiple decisions are to be made over time. I then argue that these problems force us to choose between commonsense deontological morality and a more consequentialist morality. I suggest that we should choose the latter.

This book is a collection of essays on the philosophy of life’s meaning in contemporary society. Topics range from antinatalism, meaning of life, the trolley problem, to painless civilization. I am now writing a comprehensive philosophy book on those topics, but it will take several years to complete; hence, I decided to make a handy book to provide readers with an outline of the philosophical approaches to the meaning of life that I have in mind. -/- Chapter One discusses the (...) definition, history, and category of antinatalism. Antinatalism is the thought that all human beings or all sentient beings should not be born. Although I am not an antinatalist, I believe that antinatalism poses an important question about procreation and the meaning of our lives. This is why I presented an overview of antinatalistic thoughts in the past and the present and also performed an analytical examination of their arguments. -/- In Chapter Two, I take up Philosopher Thaddeus Metz’s argument on meaning in life, especially his fundamentality theory, and claim that “the heart of meaning in life,” which is the concept I propose in this chapter, cannot be compared with anything whatsoever. -/- Chapter Three deals with the concept of “birth affirmation,” which means that I can say “yes” to my having been born. I believe that birth affirmation is one of the most promising ideas that can contribute to contemporary philosophical discussions on meaning in life, and I call this approach “an affirmation-based approach to meaning in life.” The concept of birth affirmation has two dimensions: the psychological dimension and the philosophical dimension. I would like to show in this chapter that it is difficult to clarify what it actually means to say “yes” to my having been born. -/- Chapter Four discusses the relationship between the dropping of the atomic bombs and the trolley problem. I argue that the dropping of atomic bombs was a typical example of the events that contained the logic of the trolley problem in both their decision-making processes and justifications. I further argue that the trolley problem has its own unique problems, which I call “the problem of the trolley problem.” This problem has been overlooked in academic discussions of the trolley problem. I also refer to a religious aspect of this problem. -/- In Chapter Five, I talk about the “philosophy of life” as an academic discipline. We have the philosophy of language, the philosophy of religion, and the philosophy of history, but why don’t we have the philosophy of life in the field of philosophy? Of course, we have Lebensphilosophie, but it does not cover philosophical discourses in ancient worlds, nor current analytical approaches to the concepts of life and death. A new research field is required to advance contemporary philosophy. -/- In Chapter Six, I illustrate an outline of my “painless civilization” theory, a criticism of contemporary civilization that deprives us of a joy of life in exchange for eliminating pain and suffering. I also discuss the concept of “fundamental sense of security,” which is considered indispensable for us to be able to live a life without regret. (shrink)

The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in (...) important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue-ethical view as such.

How compelling is radical normative pluralism, i.e. the view that contrary moral positions (deontological, consequentialist and so on) are all morally acceptable even in one given case? In ‘A Hostage Situation’ (2019), Saul Smilansky presents a thought experiment about moral decisions in life-and-death situations. According to Smilansky, the Hostage Situation (HS) reveals a rather puzzling and radical normative pluralistic picture, according to which even in life-and-death decisions, many moral choices that sometimes contradict each other are more or less equitable or (...) at least morally acceptable simultaneously. He argues that there is a paradigmatic difference between HS and Trolley-Problem-type cases (TP); according to him, the decision in TP is always single-valued, so one cannot be pluralistic in a plausible way—that is, one cannot rationally accept both options at the same time. TP, he claims, has been a misleading paradigmatic example; the radically pluralistic result of HS may be a better paradigm for much of morality. I argue that Smilansky should have gone further, and that a proper understanding of HS and TP reveals that, far from being in conflict, both thought experiments support a radical normative pluralism. Thus, building upon Smilansky’s work but offering a very different position, I present in this paper a radical, novel interpretation of Trolley-Problem-type cases, which, if convincing, should significantly affect the way we think about normative moral theory.

In this paper, I set out a new Kantian approach to resolving conflicts between moral obligations for highly autonomous machine agents. First, I argue that efforts to build explicitly moral autonomous machine agents should focus on what Kant refers to as duties of right, which are duties that everyone could accept, rather than on duties of virtue (or “ethics”), which are subject to dispute in particular cases. “Moral” machines must first be rightful machines, I argue. I then show how this (...) shift in focus from ethics to a standard of public right resolves the conflicts in what is known as the "trolley problem" for autonomous ma-chine agents. Finally, I consider how a deontic logic suitable for capturing duties of right might meet Kant’s requirement that rightfully enforceable obligations be consistent in a system of equal freedom under universal law.

As the trolley problem runs its course, consequentialists tend to adopt one of two strategies: silently take comfort in the fact that deontological rivals face their own enduring difficulties, or appeal to cognitive psychology to discredit the deontological intuitions on which the trolley problem depends. I refer to the first strategy as silent schadenfreude and the second as debunking attack. My aim in this paper is to argue that consequentialists ought to reject both strategies and instead opt for what I (...) call robust advantage. This strategy emphasizes the intricate calculations that consequentialists employ to defend against objections based on friendship and integrity. I argue that these calculations offer consequentialism an explanatory advantage over deontology in the context of the trolley problem. It requires striking a delicate balance between deeply internalized dispositions to avoid causing harm and a context-sensitive ability to prevent disasters; however, empirical data help consequentialism on this front by illustrating that the integration of separate cognitive functions is an ordinary part of human psychology.

Self-driving cars currently face a lot of technological problems that need to be solved before the cars can be widely used. However, they also face ethical problems, among which the question of crash-optimization algorithms is most prominently discussed. Reviewing current debates about whether we should use the ethics of the Trolley Dilemma as a guide towards designing self-driving cars will provide us with insights about what exactly ethical research does. It will result in the view that although we need the (...) ethics of the Trolley Dilemma as important input for self-driving cars, the route towards simply implementing it into automated cars is blocked.

Explaining moral intuitions is one of the hot topics of recent cognitive science. In the present article we focus on a factor that attracted surprisingly little attention so far, namely the temporal order in which moral scenarios are presented. We argue that previous research points to a systematic pattern of order effects that has been overlooked until now: only judgments of actions that are normally regarded as morally acceptable are susceptible to be affected by the order of presentation, and this (...) in turn is only the case if the dilemma is immediately preceded by a dilemma in which the proposed action was considered as not morally acceptable. We conducted an experiment that largely confirmed this pattern and allowed us to analyze by what individual level responses it was generated. We argue that investigating order effects is necessary for approaching a complete descriptive moral theory. Furthermore, we discuss the implications of these findings for moral philosophy. (shrink)

The doctrine of transferred intent (or transferred “malice” in England) generally provides that if A attempts to harm B but, because of bad aim, misses and accidentally causes the same harm to befall C, A’s harmful intent vis-à-vis B is transferred to C, thus rendering A guilty of intentionally harming C. Commentators acknowledge the doctrine to be a legal fiction, but they differ regarding whether the fiction produces just results, some believing it does, others believing that A is guilty at (...) most of attempting to harm B rather than intentionally harming C. Commentators who agree that the fiction produces just results nevertheless differ regarding whether the fiction should be retained or whether A’s intent to harm “a” person, in this case, B, is the only intent that signifies for crimes of intentional harm, regardless of whom A eventually harms. Doug Husak sought to achieve reflective equilibrium between intuition and theory regarding bad-aim cases by proposing in 1996 that A be punished for attempting to harm B (rather than for harming C) but sentenced as if he had harmed B. I once believed that Husak was correct. But I now have doubts, in part because Husak, along with others, cannot explain why the strength of people’s intuitions regarding A’s responsibility in bad-aim cases depends upon (1) C’s being a reasonably foreseeable victim, and (2) C’s being harmed by the same threat of force that A initially unleashed against B. I argue that one cannot achieve reflective equilibrium in bad-aim cases without inquiring into why resulting harm matters in criminal law, and that when one does, one discovers that just as people’s intuitions regarding whether intentional harms are proximate depend upon how resulting harms occur, so, too, people’s intuitions regarding whether an actor is guilty of intentional harm depend upon how resulting harm comes about.

In this paper, I explore how to accommodate non-consequentialist constraints with a broadly value-based conception of reasons for action. It turns out that there are two grades of non-consequentialist constraints. The first grade involves attaching ethical importance to such distinctions as the doing/allowing distinction, and the distinction between intended and unintended consequences that is central to the Doctrine of Double Effect. However, at least within the value-based framework, this first grade is insufficient to explain rights, which ground weighty reasons against (...) infringing those rights that need not be outweighed even when infringing those rights is necessary for preventing a larger number of people from having their rights infringed in the same way. Such rights form a second grade of non-consequentialist constraints: within the value-based framework, this second grade is best explained in terms of the intrinsically relational values and disvalues of interpersonal interactions and relationships.

Judith Jarvis Thomson recently argued that it is impermissible for a bystander to turn a runaway trolley from five onto one. But she also argues that a trolley driver is required to do just that. We believe that her argument is flawed in three important ways. She fails to give proper weight to (a) an agent¹s claims not to be required to act in ways he does not want to, (b) impartiality in the weighing of competing patient-claims, and (c) the (...) role of patient-claims in determining agent-duties. All three of these failures can be understood in terms of what we call the Mechanics of Claims, an approach we develop for identifying and balancing competing claims in determining rights. Using that framework, one can see both why Thomson's most recent argument is mistaken, and how to think more clearly about deontological choices generally. (shrink)

Withholding and withdrawing treatment are widely regarded as ethically equivalent in medical guidelines and ethics literature. Health care personnel, however, widely perceive moral differences between withholding and withdrawing. The proponents of equivalence argue that any perceived difference can be explained in terms of cognitive biases and flawed reasoning. Thus, policymakers should clear away any resistance to accept the equivalence stance by moral education. To embark on such a campaign of changing attitudes, we need to be convinced that the ethical analysis (...) is correct. Is it? In this article, I take a closer look at the moral relation between withholding and withdrawing. My conclusion is that withholding and withdrawing are not in general ethically equivalent. Thus, medical guidelines should be rewritten, and rather than being “educated” away from their sound judgments, medical professionals and patients should have nuanced medico-ethical discussions regarding withholding and withdrawing treatment.

Inspired by the success of generative linguistics and transformational grammar, proponents of the linguistic analogy (LA) in moral psychology hypothesize that careful attention to folk-moral judgments is likely to reveal a small set of implicit rules and structures responsible for the ubiquitous and apparently unbounded capacity for making moral judgments. As a theoretical hypothesis, LA thus requires a rich description of the computational structures that underlie mature moral judgments, an account of the acquisition and development of these structures, and an (...) analysis of those components of the moral system that are uniquely human and uniquely moral. In this paper we present the theoretical motivations for adopting LA in the study of moral cognition: (a) the distinction between competence and performance, (b) poverty of stimulus considerations, and (c) adopting the computational level as the proper level of analysis for the empirical study of moral judgment. With these motivations in hand, we review recent empirical findings that have been inspired by LA and which provide evidence for at least two predictions of LA: (a) the computational processes responsible for folk-moral judgment operate over structured representations of actions and events, as well as coding for features of agency and outcomes; and (b) folk-moral judgments are the output of a dedicated moral faculty and are largely immune to the effects of context. In addition, we highlight the complexity of the interfaces between the moral faculty and other cognitive systems external to it (e.g., number systems). We conclude by reviewing the potential utility of the theoretical and empirical tools of LA for future research in moral psychology. (shrink)

McMahan argues that justification defeats liability to defensive attack (which would undermine the thesis of the "moral equality of combatants"). In response, I argue, first, that McMahan’s attempt to burden the contrary claim with counter-intuitive implications fails; second, that McMahan’s own position implies that the innocent civilians do not have a right of self-defense against justified attackers, which neither coheres with his description of the case (the justified bombers infringe the rights of the civilians) nor with his views about rights (...) forfeiture, is unsupported by independent argument, and, in any case, extremely implausible and counter-intuitive; and third, that his interpretation of the insulin case confuses the normative relations between an agent’s justification and non-liability on the one hand and permissible or impermissible interference with the agent’s act on the other. Similar confusions, fourth, affect his discussion of liability to compensation. (shrink)

Residents with dementia in long-term care facilities (LTCFs) often receive antipsychotic (AP) medications without clear clinical indications. One non-clinical factor influencing the use of APs in LTCFs is low staff levels. Often, using APs is viewed and rationalised by healthcare professionals in LTCFs as a lesser evil option to manage low staff levels. This paper investigates the ethical plausibility of using APs as a lesser of two evils in resource-constrained LTCFs. I examine the practice vis-à-vis the three frequently invoked conditions (...) of lesser evil justifications as specified in the wider philosophical literature. These conditions include (1) the necessity condition, (2) the condition of sensitivity to both deontic (ie, constraint-based) and non-deontic (ie, outcome-based) considerations and (3) the commensurability condition. I argue that there are considerable difficulties in demonstrating that the practice in question satisfies the conditions of lesser evil justifications. In particular, there are major difficulties in satisfying the condition of sensitivity to deontic and outcome-based considerations, and the commensurability condition. I also argue that the current philosophical debate on lesser-evil justifications is not straightforwardly applicable to the practice of using APs for non-clinical purposes in LTCFs. I contend that caregivers are not so-called ‘generic’ agents, and the assumed rarity of lesser evil cases is questionable. I conclude that until further work is done to resolve these issues, the lesser evil reasoning cannot be, at least routinely, used to formulate robust moral justifications for the practice in question.

Intentions have been a central subject of research since contemporary philosophy of action emerged in the middle of the twentieth century. For almost that entire period, the approach has been to treat the study of intentions as separate from the study of morality. This essay offers a brief overview of that history and then suggests some ways forward, as exemplified by the essays collected in this volume.

The rightness and wrongness of actions fits on a continuous scale. This fits the way we evaluate actions chosen among a diverse range of options, even though English speakers don’t use the words “righter” and “wronger”. I outline and defend a version of scalar consequentialism, according to which rightness is a matter of degree, determined by how good the consequences are. Linguistic resources are available to let us truly describe actions simply as right. Some deontological theories face problems in accounting (...) for degrees of rightness, as they don't invoke continuous parameters among the right-making features of action. (shrink)

Is there a reason to prevent deontological wrongdoing—an action that is wrong due to the violation of a decisive deontological constraint? This question is perplexing. On the one hand, the intuitive response seems to be positive, both when the question is considered in the abstract and when it is considered with regard to paradigmatic cases of deontological wrongdoing such as Bridge and Transplant. On the other hand, common theoretical accounts of deontological wrongdoing do not entail this answer, since not preventing (...) wrongdoing does not necessarily amount to doing harm or intending harm, for example. The puzzle is reinforced due to the fact that the intuitive response to other cases seems to be different, namely that there is no reason in favour of preventing deontological wrongdoing. This question is thus interesting in itself. It might also shed light on additional questions such as the “paradox of deontology” and the appropriate response to wrongful actions more generally. Yet, despite its importance, this question is typically overlooked. The paper explores this question. (shrink)

According to an appealing and common view, the moral status of an action – whether it is wrong, for example – is sometimes important in itself in terms of the moral status of other actions – especially those that respond to the original action. This view is especially influential with respect to the criminal law. It is accepted not only by legal moralists but also by adherents of the harm principle, for example. In this paper, I argue against this view. (...) The main arguments emphasize the distinctions between the moral status of actions, consequences, and agents. I argue that what matters, in terms of other actions, is not the moral status of the original action but rather other factors that may be confused with it, such as the moral status of its consequences – whether they are good or bad – and the moral status of the agent – whether she is praiseworthy or blameworthy. The intuitive appeal of the common view is, I argue, at least partly due to a conflation of these factors. Most importantly, once we recall the distinctions between these factors, we can see more clearly that this view lacks a compelling rationale. Or, at least, that it is based on assumptions that, first, are much more controversial than their conclusion, and, second, do not support every aspect of this view – and thus do not offer a unified foundation for this view.

This article addresses a dilemma about autonomous vehicles: how to respond to trade-off scenarios in which all possible responses involve the loss of life but there is a choice about whose life or lives are lost. I consider four options: kill fewer people, protect passengers, equal concern for survival, and recognize everyone’s interests. I solve this dilemma via what I call the new trolley problem, which seeks a rationale for the intuition that it is unethical to kill a smaller number (...) of people to avoid killing a greater number of people based on numbers alone. I argue that killing a smaller number of people to avoid killing a greater number of people based on numbers alone is unethical because it disrespects the humanity of the individuals in the smaller-numbered group. I defend the recognize-everyone’s-interests algorithm, which will probably kill fewer people but will not do so based on numbers alone. (shrink)

Recent empirical work appears to suggest that the moral intuitions of professional philosophers are just as vulnerable to distorting psychological factors as are those of ordinary people. This paper assesses these recent tests of the ‘expertise defense’ of philosophical intuition. I argue that the use of familiar cases and principles constitutes a methodological problem. Since these items are familiar to philosophers, but not ordinary people, the two subject groups do not confront identical cognitive tasks. Reflection on this point shows that (...) these findings do not threaten philosophical expertise—though we can draw lessons for more effective empirical tests. (shrink)

Opioid and sedative use are common ‘active’ practices in the provision of mainstream palliative care services, and are typically distinguished from euthanasia on the basis that they do not shorten survival time. Even supposing that they did, it is often argued that they are justified and distinguished from euthanasia via appeal to Aquinas’ Doctrine of Double Effect. In this essay, I will appraise the empirical evidence regarding opioid/sedative use and survival time, and argue for a position of agnosticism. I will (...) then argue that the Doctrine of Double Effect is a useful ethical tool but is ultimately not a sound ethical principle, and even if it were, it is unclear whether palliative opioid/sedative use satisfy its four criteria. Although this essay does not establish any definitive proofs, it aims to provide reasons to doubt—and therefore weaken—the often-claimed ethical distinction between euthanasia and palliative opioid/sedative use.

Reflective equilibrium —the idea that we have to justify our judgments and principles through a process of mutual adjustment—is taken to be a central method in philosophy. Nonetheless, conceptions of RE often stay sketchy, and there is a striking lack of explicit and traceable applications of it. This paper presents an explicit case study for the application of an elaborate RE conception. RE is used to reconstruct the arguments from Thomson’s paper “Turning the Trolley” for why a bystander must not (...) divert a runaway trolley from five workmen onto one. Analyzing Thomson’s resulting position with the RE-criteria has two main results: Firstly, the adjustment of one of her commitments can be defended. Secondly, no justified position in RE was reached. With respect to RE as a method, the main results from this application are: There is at least one conception of RE that is sufficiently specified to be applicable; the RE criteria put real constraints on the process of justification; and an explicit application of RE has benefits in terms of clarity while at the same time providing guidance for how the justificatory process could be continued.

Some philosophers defend the fact-relative view of moral rights against harm:Whether B infringes A's right not to be harmed by ϕ-ing depends on what will in fact occur if B ϕs. B's knowledge of, or evidence about, the exact consequences of her ϕ-ing are irrelevant to the question of whether her ϕ-ing constitutes an infringement of A's right not to be harmed by B.In this paper I argue that the fact-relative view of moral rights is mistaken, and I argue for (...) an alternative view whereby our rights against harm depend on what we can reasonably demand of others. I illustrate the importance of this conclusion with a discussion of liability to defensive harm. (shrink)

In 2021, Germany passed the first law worldwide that regulates dilemma situations with autonomous cars. Against this background, this article investigates the permissibility of trade-offs between human lives in the context of self-driving cars. It does so by drawing on the debate about the traditional trolley problem. In contrast to most authors in the relevant literature, it argues that the debate about the trolley problem is both directly and indirectly relevant for the ethics of crashes with self-driving cars. Drawing on (...) its direct normative relevance, the article shows that trade-offs are permissible in situations with self-driving cars that are similar to paradigmatic trolley cases. In scenarios that are unlike paradigmatic trolley cases, the debate about the trolley problem can have indirect normative relevance because it provides reasons against the use of moral theories and principles that cannot account for the trolley problem.

This article considers one seemingly compelling justification for immigration restrictions: that they help restrict the brain drain of skilled workers from poor states. For some poor states, brain drain is a severe problem, sapping their ability to provide basic services. Yet this article finds that justifying immigration restrictions on brain drain grounds is far from straightforward. For restrictions to be justified, a series of demanding conditions must be fulfilled. Brain drain does provide a successful argument for some immigration restrictions, but (...) it is an argument that fails to justify restrictions beyond a small minority of cases. (shrink)

Self-driving cars hold out the promise of being safer than manually driven cars. Yet they cannot be a 100 % safe. Collisions are sometimes unavoidable. So self-driving cars need to be programmed for how they should respond to scenarios where collisions are highly likely or unavoidable. The accident-scenarios self-driving cars might face have recently been likened to the key examples and dilemmas associated with the trolley problem. In this article, we critically examine this tempting analogy. We identify three important ways (...) in which the ethics of accident-algorithms for self-driving cars and the philosophy of the trolley problem differ from each other. These concern: the basic decision-making situation faced by those who decide how self-driving cars should be programmed to deal with accidents; moral and legal responsibility; and decision-making in the face of risks and uncertainty. In discussing these three areas of disanalogy, we isolate and identify a number of basic issues and complexities that arise within the ethics of the programming of self-driving cars. (shrink)

In this article I attempt to show conclusively that the apparent intrinsic difference between causing collateral damage and directly attacking innocents is an illusion. I show how eleven morally irrelevant alterations can transform an apparently permissible case of harming as a side-effect into an apparently impermissible case of harming as a means. The alterations are as obviously irrelevant as the victims’ skin colour, and consistently treating them as relevant would have unacceptable implications for choices between more and less harmful ways (...) of securing greater goods. This shows not only how the principles philosophers have proposed for distinguishing between these cases cannot withstand scrutiny, but how we can be sure that there are no relevant differences yet to be discovered. I conclude by considering reasons to think that there are deontological constraints against harming, but that they apply just as forcefully against collateral harms as they do against intended harms.

People often judge it unacceptable to directly harm a person, even when this is necessary to produce an overall positive outcome, such as saving five other lives. We demonstrate that similar judgments arise when people consider damage to owned objects. In two experiments, participants considered dilemmas where saving five inanimate objects required destroying one. Participants judged this unacceptable when it required violating another’s ownership rights, but not otherwise. They also judged that sacrificing another’s object was less acceptable as a means (...) than as a side-effect; judgments did not depend on whether property damage involved personal force. These findings inform theories of moral decision-making. They show that utilitarian judgment can be decreased without physical harm to persons, and without personal force. The findings also show that the distinction between means and side-effects influences the acceptability of damaging objects, and that ownership impacts utilitarian moral judgment. (shrink)

1. The problemLewis identifies the monadic property being F with the set of all actual and possible Fs; the dyadic relation R is identified with the set of actual and possible pairs of things that are related by R; and so on . 1 Egan has argued that the fact that some properties have some of their properties contingently leads to trouble: " Let @ be the actual world, in which being green is [someone's] favourite property, and let w be (...) a world in which being green is [nobody's] favourite property. Since being green is somebody's favourite property in @, it must be a member of … being somebody's favourite property. Since being green is not anybody's favourite property in w, it must not be a member of being somebody's favourite property. Contradiction. " Egan suggests identifying properties with functions from worlds to extensions. However, as Lewis and others have complained, this has the drawback of turning monadic properties into relations . 2 In this article, we shall show that the Lewisian has the resources to block the above argument while simultaneously respecting the adicity of the relevant property and the contingency of the predication without changing his theory of properties. However, our analysis reveals a hidden ambiguity in the Lewisian conception of properties, and on either disambiguation the resulting account of properties seems inadequate.2. On ‘being someone's favourite property’The phrase ‘ being someone's favourite property’ is ambiguous. Given Lewis's ontology of possibilia, where the phrase picks out a monadic property it is not one that is possessed contingently; where it picks out a property that is possessed contingently it is not one that is monadic. But the argument works only if being someone's favourite property is both monadic and possessed contingently.Why should …. (shrink)

In the third volume of On What Matters, Derek Parfit argued that the distinction between imposing a newly created threat on someone and making what threatens some people instead threaten someone else has no genuine moral significance. This article's central thesis is that although there is much to learn from Parfit's arguments, they are ultimately unsuccessful at establishing that the redirected versus newly created threats distinction is morally irrelevant. In particular, I show that my Causal Sequences Principle specifies this distinction (...) in such a way that it is immune to Parfit's objections against the Redirection Principle. It follows that any moral theory that can provide a sound rationale for the Causal Sequences Principle can solve the trolley problem. (shrink)

In The Ends of Harm Victor Tadros develops an alternative to consequentialist, and non-consequentialist retributivist, accounts of the justifiability of punishment: the duty view. Crucial to this view is the claim that wrongdoers incur an enforceable duty to remedy their wrongs. They cannot undo them, but they can do something that is almost as good—namely, by submitting to appropriate punishment, which will deter potential wrongdoers in the future, reduce their victim’s risk of suffering similar wrongs again. Admittedly, this involves harming (...) wrongdoers as a means to an end, but according to Tadros the ‘means principle’ that we should not harm others as a means, properly construed, does not apply to cases where the victim has an enforceable duty to bear the kind of harm that he or she is being made to suffer. In this article, I shall express reservations about Tadros’ defense and interpretation of the means principle. In presenting his position, Tadros also sets out some interesting anti-retributivist considerations casting doubt on the idea that wrongdoers’ suffering is non-instrumentally good. I shall challenge these. Finally, I shall suggest that the duty view may have counterintuitive implications in relation to wrongs where the offender helps to lower the risk that victims will be subjected to similar wrongs in ways other than by being punished.

It is sometimes asserted that enabling harm is morally equivalent to allowing harm. In this article, I criticize this view. Positively, I show that cases involving self-defence and cases involving people acting on the basis of a reasonable belief to the effect that certain obstacles to harm will remain in place, or will be put in place, show that enabling harm is harder to justify than allowing it. Negatively, I argue that certain cases offered in defence of the moral equivalence (...) thesis fail, because either their similarity with the archetypal trolley case limits their relevance to an assessment of this thesis, or they are compromised by their reliance on the elusive notion of a situation being completely stable.

Many assume that the best, and perhaps only, way to address the so-called Problem of Evil is to claim that God does not do evil, but that God merely allows evil. This assumption depends on two claims: the doing-allowing distinction exists and the doing-allowing distinction is morally significant. In this paper I try to undermine both of these claims. Against I argue that some of the most influential analyses of the doing-allowing distinction face grave difficulties and that these difficulties are (...) only exacerbated when applied to God. Against I argue that broadly Kantian considerations give a better explanation of the moral differences in paradigm cases than the doing-allowing distinction and, when applied to God, effectively dissolve the moral significance of the doing-allowing distinction. The upshot of this is that those who claim God does evil are no worse off than those who claim God allows evil regarding the PoE. (shrink)

In recent years, a number of philosophers have conducted empirical studies that survey people's intuitions about various subject matters in philosophy. Some have found that intuitions vary accordingly to seemingly irrelevant facts: facts about who is considering the hypothetical case, the presence or absence of certain kinds of content, or the context in which the hypothetical case is being considered. Our research applies this experimental philosophical methodology to Judith Jarvis Thomson's famous Loop Case, which she used to call into question (...) the validity of the intuitively plausible Doctrine of Double Effect. We found that intuitions about the Loop Case vary according to the context in which the case is considered. We contend that this undermines the supposed evidential status of intuitions about the Loop Case. We conclude by considering the implications of our findings for philosophers who rely on the Loop Case to make philosophical arguments and for philosophers who use intuitions in general. (shrink)

In traditional armchair methodology, philosophers attempt to challenge a thesis of the form ‘F iff G’ or ‘F only if G’ by describing a scenario that elicits the intuition that what has been described is an F that isn’t G. If they succeed, then the judgment that there is, or could be, an F that is not G counts as good prima facie evidence against the target thesis. Moreover, if these intuitions remain compelling after further (good faith) reflection, then traditional (...) armchair methodology takes the judgment to be serious (though not infallible) evidence against the target thesis—call it secunda facie evidence—that should not be discounted as long as those intuitions retain their force. Some philosophers, however, suggest that this methodology is incompatible with epistemological naturalism, the view that philosophical inquiry should be sensitive to empirical observations, and argue that traditional armchair methodology must deemphasize the role of intuitions in philosophical inquiry. In my view, however, this would be a mistake: as I will argue, the most effective way to promote philosophical progress is to treat intuitions as having the (prima and secunda) evidential status I’ve described. But I will also argue that philosophical inquiry can produce a theory that is sensitive to empirical observations and the growth of empirical knowledge, even if it gives intuitions the prima- and secunda-facie evidential status that traditional armchair methodology demands—and thus that traditional armchair methodology, if properly practiced, need not be abandoned by naturalists, or even (except for a few exceptions) be much revised.

Crashes involving self-driving cars at least superficially resemble trolley dilemmas. This article discusses what lessons machine ethicists working on the ethics of self-driving cars can learn from trolleyology. The article proceeds by providing an account of the trolley problem as a paradox and by distinguishing two types of solutions to the trolley problem. According to an optimistic solution, our case intuitions about trolley dilemmas are responding to morally relevant differences. The pessimistic solution denies that this is the case. An optimistic (...) solution would yield first-order moral insights for the ethics of self-driving cars, but such a solution is difficult to come by. More plausible is the pessimistic solution, and it teaches us a methodological lesson. The lesson is that machine ethicists should discount case intuitions and instead rely on intuitions and judgments at a higher level of generality. (shrink)

This paper argues against the view that trolley cases are of little or no relevance to the ethics of automated vehicles. Four arguments for this view are outlined and rejected: the Not Going to Happen Argument, the Moral Difference Argument, the Impossible Deliberation Argument and the Wrong Question Argument. In making clear where these arguments go wrong, a positive account is developed of how trolley cases can inform the ethics of automated vehicles.

:This essay considers complications introduced by the Trolley Problem to the discussion of whether and when harming some for the sake of helping others would be unjustified. It first examines Guido Pincione’s arguments for the conclusion that the permissibility of a bystander turning a runaway trolley from killing five people toward killing one other person instead may undermine one moral argument for political libertarianism and against redistributive taxation, namely that we may not harm some people in order to help others (...) to a greater degree. It then considers both the bearing on Pincione’s argument of recent objections to the permissibility of turning the trolley, as well as the soundness of the objections. Finally, the essay considers the relevance of trolley cases for developing a theory of aggression, insofar as aggression is the unjustified use of force that is either foreseen or intended.

Ethical theory often starts with our intuitions about particular cases and tries to uncover the principles that are implicit in them; work on the ‘trolley problem’ is a paradigmatic example of this approach. But ethicists are no longer the only ones chasing trolleys. In recent years, psychologists and neuroscientists have also turned to study our moral intuitions and what underlies them. The relation between these two inquiries, which investigate similar examples and intuitions, and sometimes produce parallel results, is puzzling. Does (...) it matter to ethics whether its armchair conclusions match the psychologists’ findings? I argue that reflection on this question exposes psychological presuppositions implicit in armchair ethical theorising. When these presuppositions are made explicit, it becomes clear that empirical evidence can (and should) play a positive role in ethical theorising. Unlike recent assaults on the armchair, the argument I develop is not driven by a naturalist agenda, or meant to cast doubt on the reliability of our moral intuitions; on the contrary, it is even compatible with non-naturalism, and takes the reliability of intuition as its premise. The argument is rather that if our moral intuitions are reliable, then psychological evidence should play a surprisingly significant role in the justification of moral principles. (shrink)

Thomson's goal in presenting her famous Trolley problem is to evince an explanatory weakness in the principle that killing is worse than letting die. Along the way, she tries to evince a similar weakness in the Kantian principle forbidding the use of people as mere means (henceforth: the Kantian prohibition). However, Thomson's negative assessment of the Kantian prohibition is unwarranted, and that is what this paper aims to show. The paper is divided into three sections. In the first, I introduce (...) the Kantian prohibition on using persons as mere means. In the second, I explain where the Trolley problem gets onto the wrong track. To do so, I shall engage with Kleingeld's recent and ingenious Kantian contribution to the trolley problem literature. In the third, I sketch some of what is needed for a Kantian solution to the Trolley problem. (shrink)

The doing/allowing distinction plays an important role in our thinking about a number of legal issues, such as the need for criminal process protections, prohibitions on torture, the permissibility of the death penalty and so on. These are areas where, at least initially, there seem to be distinctions between harms that the state inflicts and harms that it merely allows. In this paper I will argue for the importance of the doing/allowing distinction as applied to state action. Sunstein, Holmes, Vermeule (...) and others have presented influential arguments for the claim that where the state is concerned the doing/allowing distinction has no moral significance, even if it does elsewhere. I show that these arguments can be resisted. In doing so, I defend some important distinctions and principles that help us understand the state’s role in protecting people from harm. (shrink)
