Moral theorists like Singer and Greene argue that we should discount intuitions about ‘up-close-and-personal’ moral dilemmas because they are more likely than intuitions about ‘impersonal’ dilemmas to be artifacts of evolution. But by that reasoning, it seems we should ignore the evolved, ‘up-close-and-personal’ intuition to save a drowning child in light of the too-new-to-be-evolved, ‘impersonal’ intuition that we need not donate to international famine relief. This conclusion seems mistaken and horrifying, yet it cannot be the case both that ‘up-close-and-personal’ intuitions (...) are more reliable than ‘impersonal’ intuitions, and vice versa. Thus, Singer’s evolutionary debunking argument proves too much, and should not be taken seriously. However, Singer’s debunking argument is typical of an entire class of arguments that seeks to debunk normative principles by reference to evolution. This entire class of argument, I argue, therefore also proves too much to be taken seriously. (shrink)

Trolley cases are widely considered central to the ethics of autonomous vehicles. We caution against this by identifying four problems. Trolley cases, given technical limitations, rest on assumptions that are in tension with one another. Furthermore, trolley cases illuminate only a limited range of ethical issues insofar as they cohere with a certain design framework. Furthermore, trolley cases seem to demand a moral answer when a political answer is called for. Finally, trolley cases might be epistemically problematic in several ways. (...) To put forward a positive proposal, we illustrate how ethical challenges arise from mundane driving situations. We argue that mundane situations are relevant because of the specificity they require and the scale they exhibit. We then illustrate some of the ethical challenges arising from optimizing for safety, balancing safety with other values such as mobility, and adjusting to incentives of legal frameworks. (shrink)

I argue that the separation of the conjoined Attard twins of Manchester was not morally justified as it involved intentionally internally affecting (“invading”) the body of the weaker twin without permission and without any advantage to her.

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)

In the last decade, philosophers have offered a number of proposals concerning the logical form of hypothetical cases, or thought experiments, as these are used for purposes of testing philosophical claims. In this paper, I discuss what the desiderata for a formal proposal are. Employing a comparison with general philosophy of science, I suggest that one important desideratum is to highlight recurrent patterns of disagreement surrounding cases. I advocate a proposal in propositional modal logic which, I argue, better meets this (...) desideratum than competing proposals. I also sketch how this proposal may be extended into more fine grained analyses, employing counterfactual conditionals yet avoiding certain problems due to so-called "deviant realizations". (shrink)

Moral judgment has typically been characterized as a conflict between emotion and reason. In recent years, a central concern has been determining which process is the chief contributor to moral behavior. While classic moral theorists claimed that moral evaluations stem from consciously controlled cognitive processes, recent research indicates that affective processes may be driving moral behavior. Here, we propose a new way of thinking about emotion within the context of moral judgment, one in which affect is generated and transformed by (...) both automatic and controlled processes, and moral evaluations are shifted accordingly. We begin with a review of how existing theories in psychology and neuroscience address the interaction between emotion and cognition, and how these theories may inform the study of moral judgment. We then describe how brain regions involved in both affective processing and moral judgment overlap and may make distinct contributions to the moral evaluation process. Finally, we discuss how this way of thinking about emotion can be reconciled with current theories in moral psychology before mapping out future directions in the study of moral behavior. (shrink)

The prospective introduction of autonomous cars into public traffic raises the question of how such systems should behave when an accident is inevitable. Due to concerns with self-interest and liberal legitimacy that have become paramount in the emerging debate, a contractarian framework seems to provide a particularly attractive means of approaching this problem. We examine one such attempt, which derives a harm minimisation rule from the assumptions of rational self-interest and ignorance of one’s position in a future accident. We contend, (...) however, that both contractarian approaches and harm minimisation standards are flawed, due to a failure to account for the fundamental difference between those ‘involved’ and ‘uninvolved’ in an impending crash. Drawing from classical works on the trolley problem, we show how this notion can be substantiated by reference to either the distinction between negative and positive rights, or to differences in people’s claims. By supplementing harm minimisation with corresponding constraints, we can develop crash algorithms for autonomous cars which are both ethically adequate and promise to overcome certain significant practical barriers to implementation.

Can someone be reasonable or justified in accepting a specific moral judgment not based on the prior acceptance of a general exceptioness moral principle, where acceptance of a general principle might be tacit or implicit and might not be expressible in language? This issue is an instance of a wider issue about direct or transductive inference. Developments in statistical learning theory show that such an inference can be more effective than alternative methods using inductive generalization and so can be reasonable. (...) This result carries over to moral transduction, although it is a difficult empirical issue whether people actually engage in any sort of transduction, including moral transduction. (shrink)

INTRODUCTION In my view, justice is entirely conventional; indeed, all of morality consists in conventions that are the result of continual tacit bargaining and adjustment. This is not to say social arrangements are just whenever they are in accordance with the principles of justice accepted in that society. We can use our own principles of justice in judging the institutions of another society, and we can appeal to some principles we accept in order to criticize other principles we accept. To (...) use David Hume's model of the relevant sort of convention, two people rowing a boat each continually adjusts his or her rate of rowing to the other so that they come to row at the same rate, a rate that is normally somewhere between the rate at which each would prefer to row. In the same way the basic principles of justice accepted by people of different powers and resources are the result of a continually changing compromise affecting such things as the relative importance attached to helping others as compared with the importance attached to not harming others. Hume's rowers provide an example of a “convention” that is normally completely tacit. There are other models in which the bargaining can be more explicit, for example when a seller comes to set prices that are acceptable to customers, when employers reach understandings with employees concerning wages, or when political groups influence legislation. I want eventually to consider the implications for moral reasoning and argument of the thesis that principles of justice are entirely the result of implicit bargaining and convention of this sort.

Ethical decision-making research has centered on Rest’s framework that represents a rational, nonaffective model for ethical decision making. However, research in human cognition suggesting a “dual-processing” framework, composed of both rational and affective components, has been relatively ignored in the ethical decision-making literature. Examining dual-processing literature, it seems affect might be an important factor in decision making when a person’s mood is congruent with the task or situational context frame. Given that ethical decisions are serious and complex tasks, it is (...) proposed here that inducing a negative affective state might produce mood congruence, reinforce the salience of emotion for ethical decision makers, and lead to differences in decision processing. Evidence is presented documenting differences in the decisions made by ethical decision makers in a negative affective state as compared to those in either a positive or neutral affective state.

Descriptions of Gettier cases can be interpreted in ways that are incompatible with the standard judgment that they are cases of justified true belief without knowledge. Timothy Williamson claims that this problem cannot be avoided by adding further stipulations to the case descriptions. To the contrary, we argue that there is a fairly simple way to amend the Ford case, a standard description of a Gettier case, in such a manner that all deviant interpretations are ruled out. This removes one (...) major objection to interpreting our judgments about Gettier cases as strict conditionals. (shrink)

Contemporary moral psychology has been enormously enriched by recent theoretical developments and empirical findings in evolutionary biology, cognitive psychology and neuroscience, and social psychology and psychopathology. Yet despite the fact that some theorists have developed specifically “social heuristic” (Gigerenzer, 2008) and “social intuitionist” (Haidt, 2007) theories of moral judgment and behavior, and despite regular appeals to the findings of experimental social psychology, contemporary moral psychology has largely neglected the social dimensions of moral judgment and behavior. I provide a brief sketch (...) of these dimensions, and consider the implications for contemporary theory and research in moral psychology. (shrink)

No one has done more over the past four decades to draw attention to the importance of, and attempt to solve, a particularly vexing problem in ethics—the Trolley Problem—than Judith Jarvis Thomson. Though the problem is originally due to Philippa Foot, Thomson showed how Foot’s simple solution would not do and offered some solutions of her own. No solution is uncontroversial and the problem remains a thorn in the side of non-consequentialist moral theory. Recently, however, Thomson has changed her mind (...) about the problem. She no longer thinks she was right to reject Foot’s solution to it. I argue that, though illuminating, Thomson’s current take on the Trolley Problem is mistaken. I end with a solution to the problem that I find promising. (shrink)

This paper examines the ethical pitfalls and challenges that non-ethicists, such as researchers and programmers in the fields of computer science, artificial intelligence and robotics, face when building moral machines. Whether ethics is “computable” depends on how programmers understand ethics in the first place and on the adequacy of their understanding of the ethical problems and methodological challenges in these fields. Researchers and programmers face at least two types of problems due to their general lack of ethical knowledge or expertise. (...) The first type is so-called rookie mistakes, which could be addressed by providing these people with the necessary ethical knowledge. The second, more difficult methodological issue concerns areas of peer disagreement in ethics, where no easy solutions are currently available. This paper examines several existing approaches to highlight the ethical pitfalls and challenges involved. Familiarity with these and similar problems can help programmers to avoid pitfalls and build better moral machines. The paper concludes that ethical decisions regarding moral robots should be based on avoiding what is immoral in combination with a pluralistic ethical method of solving moral problems, rather than relying on a particular ethical approach, so as to avoid a normative bias.

Hypothetical trolley problems are widely used to elicit moral intuitions, which are employed in the development of moral theory and the psychological study of moral judgments. The scenarios used are outlandish, and some philosophers and psychologists have questioned whether the judgments made in such unrealistic and unfamiliar scenarios are a reliable basis for theory-building. We present two experiments that investigate whether differences in moral judgment due to the role of the agent, previously found in a standard trolley scenario, persist when (...) the structure of the problem is transplanted to a more familiar context. Our first experiment compares judgments in hypothetical scenarios; our second experiment operationalizes some of those scenarios in the laboratory, allowing us to observe judgments about decisions that are really being made. In the hypothetical experiment, we found that the role effect reversed in our more familiar context, both in judgments about what the actor ought to do and in judgments about the moral rightness of the action. However, in our laboratory experiment, the effects reversed back or disappeared. Among judgments of what the actor ought to do, we found the same role effect as in the standard hypothetical trolley scenario, but the effect of role on moral judgments disappeared. (shrink)

According to Selim Berker the prevalence of consequentialism in contemporary epistemology rivals its prevalence in contemporary ethics. Similarly, and more to the point, Berker finds epistemic consequentialism, epitomized by process reliabilism, to be as misguided and problematic as ethical consequentialism. This paper shows how Berker misconstrues process reliabilism and fails to pinpoint any new or substantial defects in it.

Normative theories can be useful in developing descriptive theories, as when normative subjective expected utility theory is used to develop descriptive rational choice theory and behavioral game theory. questions are also the essence of theories of moral reasoning, a domain of higher mental processing that could not survive without normative considerations.

The recent progress in the development of autonomous cars has seen ethical questions come to the forefront. In particular, life and death decisions regarding the behavior of self-driving cars in trolley dilemma situations are attracting widespread interest in the recent debate. In this essay we want to ask whether we should implement a mandatory ethics setting for the whole of society or, whether every driver should have the choice to select his own personal ethics setting. While the consensus view seems (...) to be that people would not be willing to use an automated car that might sacrifice themselves in a dilemma situation, we will defend the somewhat contra-intuitive claim that this would be nevertheless in their best interest. The reason is, simply put, that a PES regime would most likely result in a prisoner’s dilemma. (shrink)

Is ethics a computable function? Can machines learn ethics like humans do? If teaching consists in no more than programming, training, indoctrinating… and if ethics is merely following a code of conduct, then yes, we can teach ethics to algorithmic machines. But if ethics is not merely about following a code of conduct or about imitating the behavior of others, then an approach based on computing outcomes, and on the reduction of ethics to the compilation and application of a set (...) of rules, either a priori or learned, misses the point. Our intention is not to solve the technical problem of machine ethics, but to learn something about human ethics, and its rationality, by reflecting on the ethics that can and should be implemented in machines. Any machine ethics implementation will have to face a number of fundamental or conceptual problems, which in the end refer to philosophical questions, such as: what is a human being (or more generally, what is a worthy being); what is human intentional acting; and how are intentional actions and their consequences morally evaluated. We are convinced that a proper understanding of ethical issues in AI can teach us something valuable about ourselves, and what it means to lead a free and responsible ethical life, that is, being good people beyond merely “following a moral code”. In the end we believe that rationality must be seen to involve more than just computing, and that value rationality is beyond numbers. Such an understanding is a required step to recovering a renewed rationality of ethics, one that is urgently needed in our highly technified society. (shrink)

In light of the magnitude of interpersonal harm and the risk of greater harm in the future, Ingmar Persson and Julian Savulescu have argued for pharmacological enhancement of moral behaviour. I discuss moral bioenhancement as a set of collective action problems. Psychotropic drugs or other forms of neuromodulation designed to enhance moral sensitivity would have to produce the same or similar effects in the brains of a majority of people. Also, a significant number of healthy subjects would have to participate (...) in clinical trials testing the safety and efficacy of these drugs, which may expose them to unreasonable risk. Even if the drugs were safe and effective, a majority of people would have to co-operate in a moral enhancement programme for such a project to succeed. This goal would be thwarted if enough people opted out and decided not to enhance. To avoid this scenario, Persson and Savulescu argue that moral enhancement should be compulsory rather than voluntary. But the collective interest in harm reduction through compulsory enhancement would come at the cost of a loss of individual freedom. In general, there are many theoretical and practical reasons for scepticism about the concept and goal of moral enhancement. (shrink)

When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by (...) a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms. (shrink)

It might be that intuitions are central to philosophy, and it might be that this is true because when philosophers give case‐based arguments for philosophical claims (in published philosophy), the case verdict is typically (a) an intuited proposition and (b) either left undefended or defended on the grounds that it is an intuited proposition. This paper remains neutral on these global issues, however, and instead focuses on whether there is a nontrivial (or many‐membered) class of case‐based arguments in philosophy in (...) which the case verdict is defended by appeal to background beliefs and not on the grounds that it is an intuited proposition. The paper argues that the answer is affirmative by examining seven such arguments that are referred to as “paradigm cases” of case‐based arguments in which the verdict is justified via an appeal to intuition.

When two actors have the same mental state but one happens to harm another person (unlucky actor) and the other one does not (lucky actor), the latter elicits a milder moral judgement. To understand how this outcome effect would affect post-harm interactions between victims and perpetrators, we examined how the social role from which transgressions are perceived moderates the outcome effect, and how outcome effects on moral judgements transfer to agentic and communal interpersonal goals. Three vignette experiments (N = 950) (...) revealed similar outcome effects on moral judgement across social roles. In contrast, outcome effects on agentic and communal goals varied by social role: victims exhibited the strongest outcome effects and perpetrators the weakest, with bystanders falling in between. Moral judgement did not mediate the effects of outcome severity on interpersonal goals. We discuss the possibility that outcome severity raises normative expectations regarding post-harm interactions that are unrelated to moral considerations. (shrink)

Imagine that an anthropologist returns from her study of a group of people and reports the following:They refuse to kill one person even to avert the death of all involved—including that one person;They won’t directly push someone to his death to save the lives of five others, but they will push a lever to kill him to save five others;They punish transgressors because it feels right, even when they expect the punishment to cause far more harm than good—and even when (...) the harm done by the punishment exceeds the harm done by the transgression being punished.The anthropologist’s report might lead us to conclude that these people are at least confused, and perhaps even dangerous.Here’s some bad news. Those people are us. Or so suggests recent research in experimental psychology and the neurosciences. This research indicates that our moral intuitions have a vaguely deontological character and they prompt us to make any number of judgments that appear arbitrary or otherwise unjustified, such ... -/- I contend that Greene partly misunderstands the practical implications of his own principles. If our ordinary moral judgments are to do the strategic work Greene wants them to do, he needs to endorse fullfledged Sidgwickian self-effacement for at least some areas of micro-level decision making. By the lights of some of Greene’s own arguments, people must accept the correctness—and not simply the usefulness—of the relevant intuitions in their personal conduct to satisfy utilitarian standards. I argue that removing utilitarian reasoning from micro-level decision making is consistent with Greene’s preferred strategy of using utilitarianism as a Bcommon currency^ for resolving moral conflict at the institutional level. To clarify upfront: the aim of this paper is to offer an internal criticism rather than to defend (e.g.,) the relevant empirical research, utilitarianism, self-effacement, and so on. I’m making an argument about where Greene’s own psychological and philosophical commitments should take him. (shrink)

Recent advances in virtual technologies have allowed the investigation of simulated moral actions in aversive moral dilemmas. Previous studies have employed diverse populations in order to explore these actions, with little research considering the significance of occupation on moral decision-making. For the first time, in this study we have investigated simulated moral actions in Virtual Reality made by professionally trained paramedics and fire service incident commanders who are frequently faced with and must respond to moral dilemmas. We found that specially (...) trained individuals showed distinct empathic and related personality trait scores and that these declined with years of experience working in the profession. Supporting the theory that these professionals develop resilience in moral conflict, reduced emotional arousal was observed during virtual simulations of a distressing dilemma. Furthermore, trained professionals demonstrated less regret following the execution of a moral action in virtual reality when compared to untrained control populations. We showed that, contrary to previous research, trained individuals made the same moral judgments and moral actions as untrained individuals, though showing less arousal and regret. In the face of increasing concerns regarding empathy decline in healthcare professionals, we suggest that the nature of this decline is complex and likely reflects the development of a necessary emotional resilience to distressing events.

In order to assess and understand human behavior, traditional approaches to experimental design incorporate testing tools that are often artificial and devoid of corporeal features. Whilst these offer experimental control in situations in which, methodologically, real behaviors cannot be examined, there is increasing evidence that responses given in these contextually deprived experiments fail to trigger genuine responses. This may result from a lack of consideration regarding the material makeup and associations connected with the fabric of experimental tools. In a two-year (...) collaboration, we began to experiment with the physicality of testing tools using the domain of moral psychology as a case study. This collaboration involved thinkering and prototyping methods that included direct contact and consideration of the materials involved in experimentation. Having explored the embodied nature of morality, we combined approaches from experimental psychology, moral philosophy, design thinking, and computer science to create a new testing tool for simulated moral behavior. Although the testing tool itself generated fruitful results, this paper considers the collaborative methodology through which it was produced as a route to highlight material questions within psychological research.

Antitheodicy objects to all attempts to solve the problem of evil. Its objections are almost all on moral grounds—it argues that the whole project of theodicy is morally offensive. Trying to excuse God’s permission of evil is said to deny the reality of evil, to exhibit gross insensitivity to suffering, and to insult the victims of grave evils. Since antitheodicists urge the avoidance of theodicies for moral reasons, it is desirable to evaluate the moral reasons against theodicies in abstraction from (...) the intellectual reasons for and against them. It is argued that the best known theodicies such as those based on soul-making and free will are guilty of moral faults as alleged. But Leibniz’s best of all possible worlds theory, often thought to be the most morally offensive ‘Panglossian’ theodicy, is morally blameless because it excuses God by the absolute impossibility of his choosing any world better than the present one. Theodicy should not be conceived of as a search for greater goods which may excuse God’s permitting evils. From the divine point of view, creation is an upfront choice between scenarios—in modern parlance, a Trolley problem rather than a Transplant problem. In cases of forced choice among scenarios, it is morally improper to criticize one who chooses the best. (shrink)

The famous ‘trolley problem’ began as a simple variation on an example given in passing by Philippa Foot , involving a runaway trolley that cannot be stopped but can be steered to a path of lesser harm. By switching from the perspective of the driver to that of a bystander, Judith Jarvis Thomson showed how the case raises difficulties for the normative theory Foot meant to be defending, and Thomson compounded the challenge with further variations that created still more puzzles (...) of broader interest. In recent years, her thought experiments have even been co-opted by psychologists engaged in the empirical study of moral judgment . Yet more than thirty years after launching the trolley problem, Thomson has now strikingly reversed course, retracting the very claim she had originally used to raise puzzles for Foot. I shall argue that this reversal is a mistake, leading to a needlessly counterintuitive, contrarian position about damage-control cases. Instead of overturning her earlier position, her new variations merely uncover a surprising insight about the conditions under which one may permissibly sacrifice another for a good end.1. The central case at issue is what Thomson now calls Bystander's Two Options: you are a bystander who sees a runaway trolley headed toward five innocent people who cannot move off the track; you cannot stop the trolley, but you have access to a switch that will divert it onto a side track where one innocent person is trapped. Is it permissible to throw the switch and divert the trolley toward lesser harm? The common answer, and Thomson's earlier one, is that it is: in cases like this, where there is a public threat and we can act on it so …. (shrink)

In this paper, I propose a solution to a challenge formulated by Judith Jarvis Thomson: We have to explain why the moral asymmetry between doing and allowing harm is a deep feature of our moral thinking. In a nutshell, my solution is this: It could not be otherwise. Accepting the asymmetry is indispensable for the construction and maintenance of stable moral communities. -/- My argument centrally involves mental resource management. Moral communities depend on their members’ commitment to moral norms. And, (...) I argue, community members can only be committed to these norms in the required ways without overextending their mental resources if morality contains the doing/allowing asymmetry. -/- This has two noteworthy implications. Firstly, we can and should stop discussing the asymmetry in normative ethics and, instead, regard it as “moral axiom” we cannot but accept. Secondly, even consequentialists have to accept the asymmetry but, by doing so, their view loses part of its intuitive appeal. Lastly, I turn to an objection. One might think that my indispensability argument confuses issues in moral psychology with issues in normative ethics. I reject the objection on broadly pragmatist grounds. (shrink)

Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in utilitarian ways, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past few years, especially due to the necessity of implementing moral decisions in autonomous driving vehicles. We conducted a set of experiments in which participants experienced modified trolley dilemmas as drivers in virtual reality environments. Participants had to make decisions between (...) driving in one of two lanes where different obstacles came into view. Eventually, the participants had to decide which of the objects they would crash into. Obstacles included a variety of human-like avatars of different ages and group sizes. Furthermore, the influence of sidewalks as potential safe harbors and a condition implicating self-sacrifice were tested. Results showed that participants, in general, decided in a utilitarian manner, sparing the highest number of avatars possible with a limited influence by the other variables. Derived from these findings, which are in line with the utilitarian approach in moral decision making, it will be argued for an obligatory ethics setting implemented in ADVs. (shrink)

This paper defends the use of imaginary cases in normative theorizing. Imaginary cases are used as a part of an argument and should be assessed in terms of the role they play within arguments. The paper identifies five ways in which they are used and then uses some of the best examples to bring out how they contribute to debates. While not directly akin to empirical experiments, criticisms of imaginary cases can be represented in terms of the well‐known distinction between (...) internal and external validity in social science experiments. While imaginary cases can suffer from internal and external validity problems, these do not constitute a decisive critique of their use as a method of analysis. Criticisms of imaginary cases should detail the precise form in which they are used, and why any particular use is invalid, internally or externally, in the context of the argument for which the case is presented.

Judith Jarvis Thomson has recently proposed a new argument for the thesis that killing the one in the Trolley Problem is not permissible. Her argument relies on the introduction of a new scenario, in which the bystander may also sacrifice herself to save the five. Thomson argues that those not willing to sacrifice themselves if they could may not kill the one to save the five. Bryce Huebner and Marc Hauser have recently put Thomson's argument to empirical test by asking (...) people what they should do in the new trilemma case, in which they may also sacrifice themselves. They found that the majority judge that they should either kill the one or sacrifice themselves; Huebner and Hauser argue that those numbers speak against Thomson's argument. But Thomson's argument was about the dialectical effect of the new trilemma on the traditional dilemma, rather than about the trilemma itself. Here I present the results of a study in which I asked subjects first what they should do in the trilemma and then what they should do in the traditional Trolley Problem. I found that, if asked first about the trilemma, subjects then have the intuition that killing the one in the traditional Bystander at the Switch is not permissible?exactly what Thomson's argument had predicted.

I argue against the Doctrine of Double Effect’s explanation of the moral difference between terror bombing and strategic bombing. I show that the standard thought-experiment of terror bombing and strategic bombing which dominates this debate is underdetermined with regards to the agents’ psychologies: (a) if Terror Bomber and Strategic Bomber have the same causal beliefs, then why does Terror Bomber set out to kill the children? It may then be this unwarranted and immoral choice and not the Doctrine of Double (...) Effect that explains the moral difference; (b) if the two have different causal beliefs, then we can’t rule out the counterfactual that, had Strategic Bomber had the same beliefs as Terror Bomber, she would have also acted as Terror Bomber did.

There are some interesting similarities between Aristotle’s ‘mixed actions’ in Book III of the Nicomachean Ethics and the actions often thought to be justifiable with the Doctrine of Double Effect. Here I analyse these similarities by comparing Aristotle’s examples of mixed actions with standard cases from the literature on double effect such as, amongst others, strategic bombing, the trolley problem, and craniotomy. I find that, despite some common features such as the dilemmatic structure and the inevitability of a bad effect, (...) Aristotle’s mixed actions do not count as cases justifiable through application of the Doctrine of Double Effect because they fail to meet the crucial necessary condition of the Doctrine according to which the bad effect can only be a merely foreseen side-effect and not an intended means.

Automated vehicles (AVs) are expected to operate on public roads, together with non-automated vehicles and other road users such as pedestrians or bicycles. Recent ethical reports and guidelines raise worries that AVs will introduce injustice or reinforce existing social inequalities in road traffic. One major injustice concern in today’s traffic is that different types of road users are exposed differently to risks of corporal harm. In the first part of the paper, we discuss the responsibility of AV developers to address (...) existing injustice concerns regarding risk exposure as well as approaches on how to fulfill the responsibility for a fairer distribution of risk. In contrast to popular approaches on the ethics of risk distribution in unavoidable accident cases, we focus on low and moderate risk situations, referred to as routine driving. For routine driving, the obligation to distribute risks fairly must be discussed in the context of risk-taking and risk-acceptance, balancing safety objectives of occupants and other road users with driving utility. In the second part of the paper, we present a typical architecture for decentralized automated driving which contains a dedicated module for real-time risk estimation and management. We examine how risk estimation modules can be adjusted and parameterized to redress some inequalities. (shrink)

Most people believe that suffering is intrinsically bad. In conjunction with facts about our world and plausible moral principles, this yields a pro tanto obligation to reduce suffering. This is the intuitive starting point for the moral argument in favor of interventions to prevent wild animal suffering. If we accept the moral principle that we ought, pro tanto, to reduce the suffering of all sentient creatures, and we recognize the prevalence of suffering in the wild, then we seem committed to (...) the existence of such a pro tanto obligation. Of course, competing values such as the aesthetic, scientific or moral values of species, biodiversity, naturalness or wildness, might be relevant to the all-things-considered case for or against intervention. Still, many argue that, even if we were to give some weight to such values, no plausible theory could resist the conclusion that WAS is overridingly important. This article is concerned with large-scale interventions to prevent WAS and their tractability and the deep epistemic problem they raise. We concede that suffering gives us a reason to prevent it where it occurs, but we argue that the nature of ecosystems leaves us with no reason to predict that interventions would reduce, rather than exacerbate, suffering. We consider two interventions, based on gene editing technology, proposed as holding promise to prevent WAS; raise epistemic concerns about them; discuss their potential moral costs; and conclude by proposing a way forward: to justify interventions to prevent WAS, we need to develop models that predict the effects of interventions on biodiversity, ecosystem functioning, and animals’ well-being.

Most people think it is wrong to take organs from the dead if the potential donors had previously expressed a wish not to donate. Yet people respond differently to a thought experiment that seems analogous in terms of moral relevance to taking organs without consent. We argue that our reaction to the thought experiment is most representative of our deepest moral convictions. We realize not everyone will be convinced by the conclusions we draw from our thought experiment. Therefore, we point (...) out that the state ignores consent in performing mandatory autopsies in some cases. If readers are willing to give up the permissibility of mandatory autopsies, we then offer some metaphysical arguments against posthumous harm. Drawing upon claims about bodies ceasing to exist at death and Epicurean-inspired arguments against posthumous interests, we make a case for an organ conscription policy which respects fundamental liberal principles of autonomy, bodily integrity, and property.

The phenomenon of “dirty hands” is typically framed as an issue for normative or applied ethical consideration—for example, in debates between consequentialism and nonconsequentialism, or in discussions of the morality of torture or political expediency. By contrast, this paper explores the metaethical dimensions of dirty-hands situations. First, empirically-informed arguments based on scenarios of moral dilemmas involving metaethical aspects of dirty hands are marshaled against the view that “ought implies can.” Second, a version of moral realism is conjoined with a version (...) of value-pluralism that charitably accommodates and explains the central features of the phenomenology related to dirty hands. It is not simply that agents are or are not justified in getting their hands dirty (les mains sales); rather, in certain situations, it is the nature of the moral domain itself to be intractably messy (le sale monde), such that dirty hands are unavoidable. The paper concludes by considering some important normative and psychological implications of this view. (shrink)

Responding to several leading ideas from a paper by Allen Buchanan, the present essay explores the implications of genetic enhancement for moral status. Contrary to doubts expressed by Buchanan, I argue that genetic enhancement could lead to the existence of beings so superior to contemporary human beings that we might aptly describe them as post-persons. If such post-persons emerged, how should we understand their moral status in relation to ours? The answer depends in part on which of two general models (...) of moral status—one based on respect and one based on interests—is more adequate. Buchanan tentatively argues that a respect-based model is preferable. I challenge Buchanan's view, along these lines: If we embrace a respect-based model of moral status featuring a threshold that divides persons, who are thought to have full and equal moral status, from sentient nonpersons, thought to have less moral status, then we should acknowledge a second threshold and a level of moral status higher than ours. A better option, I tentatively suggest, is to drop the idea of levels of moral status, accept that all sentient beings have moral status, and allow that some differences in interests and capacities justify some significant differences in how we should treat beings of different kinds.

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)

Historically, cognitivists considered moral choices to be determined by analytic processes. Recent theories, however, have emphasized the role of intuitive processes in determining moral choices. We propose that the engagement of analytic and intuitive processes is contingent on the type of tradeoff being considered. Specifically, when a tradeoff necessarily violates a moral principle no matter what choice is made, as in tragic tradeoffs, its resolution should result in greater moral conflict and less confidence in choice than when the tradeoff offers (...) a moral escape route, as in taboo tradeoffs. We manipulated tradeoff type in between subjects design and confirmed the prediction that tragic tradeoffs prompt more conflict and less confidence than taboo tradeoffs. The findings further revealed that moral conflict mediated the effect of tradeoff type on confidence. The study sheds light on the manner in which human minds resolve moral problems involving social agents. (shrink)
