I argue against Judith Jarvis Thomson’s solution for solving paradoxes surrounding trolley cases. I then offer my own competing, novel solution. Thomson famously proposed that what matters in trolley-type cases is whether an agent does something to a threat itself so as to minimize harm or whether the agent initiates a new threat against a person so as to minimize harm. According to her, we intuitively assume that minimizing harm is permissible in the former case (doing (...) something to a threat) but not the latter (initiating a new threat to a person). I demonstrate that this distinction does not accommodate our intuitions in all trolley-type cases. I then propose a new distinction – that of being “in the realm” and “out of the realm” - that does accommodate our intuitions across the range of trolley type cases. Bringing someone from “out” of the realm “into” the realm thus constitutes a new deontological constraint against minimizing harm. (shrink)

At the height of the Covid-19 pandemic, frontline medical professionals at intensive care units around the world faced gruesome decisions about how to ration life-saving medical resources. These events provided a unique lens through which to understand how the public reasons about real-world dilemmas involving trade-offs between human lives. In three studies (total N = 2298), we examined people’s moral attitudes toward triage of acute coronavirus patients, and found elevated support for utilitarian triage policies. These utilitarian tendencies did not stem (...) from period change in moral attitudes relative to pre-pandemic levels--but rather, from the heightened realism of triage dilemmas. Participants favored utilitarian resolutions of critical care dilemmas when compared to structurally analogous, non-medical dilemmas—and such support was rooted in prosocial dispositions, including empathy and impartial beneficence. Finally, despite abundant evidence of political polarization surrounding Covid-19, moral views about critical care triage differed modestly, if at all, between liberals and conservatives. Taken together, our findings highlight people’s robust support for utilitarian measures in the face of a global public health threat, and illustrate how hypothetical scenarios in moral psychology (e.g. trolley cases) should strive for more experiential and psychological realism, otherwise their results might not generalize to real-world moral dilemmas.

This paper deals with the core version of the Trolley Problem. In one case many people favor an act which will bring about the death of one person but save five other persons. In another case most people would refuse to “sacrifice” one person in order to save five other lives. Since the two cases seem similar in all relevant respects, we have to explain and justify the diverging verdicts. Since I don’t find current proposals of a solution (...) convincing, I propose an alternative one according to which —but not —violates two forms of equality. I also test the underlying egalitarian principle against other cases. I argue that it offers a good explanation and also a normative justification of our intuitive verdicts about the cases. (shrink)

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.

This chapter proposes a solution to the Trolley Problem in terms of the Kantian prohibition on using a person ‘merely as a means.’ A solution of this type seems impossible due to the difficulties it is widely thought to encounter in the scenario known as the Loop case. The chapter offers a conception of ‘using merely as a means’ that explains the morally relevant difference between the classic Bystander and Footbridge cases. It then shows, contrary to the standard (...) view, that a bystander who diverts the trolley in the Loop case need not be using someone ‘merely as a means’ in doing so. This makes it possible to show why the Loop scenario does not undermine the explanation of the salient moral difference between the Bystander and Footbridge cases. (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.

This article examines the implications of utilitarianism for social justice, considering different cases of the trolley problems. Utilitarianism comprises a cluster of ethical theses, which have political and legal implications. In general, utilitarianism is assumed to augment the common good, such as pleasure, happiness, satisfaction, and utility, or to reduce pain, suffering, dissatisfaction, and disutility. The article investigates a key problem whether utilitarianism brings about social justice as a moral theory. In recent literature, many moral philosophers have developed (...) several thought experiments, known as trolley problems, that help understand the utilitarian applications to social justice. Philippa Foot and others formulated several thought experiments to help explain the utilitarian difference between the maximum good and the minimum loss. Considering different cases of the trolley problem, I argue that utilitarianism does not do egalitarian justice to all people because it does not eliminate unjust inequalities in society. I hold that utilitarianism is an ethical theory without an egalitarian morality. John Rawls posited a landmark theory of social justice in contrast to the utilitarian notion of social justice. Utilitarianism does not provide social justice to the few, the minority, or the weak in the social world. So, utilitarianism is an inadequate moral theory for acquiring social justice. In qualitative research methodology, I adopt a method of an empirically informed philosophical analysis to examine documentary resources, including journal papers, academic books, and conferences and congresses.

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.

In this book chapter I argue that contrary to what is said by Paul Guyer in Kant (Routledge, 2006) Kant's moral philosophy prohibits the bystander from throwing the switch to divert the runaway trolley to a side track with an innocent person on it in order to save more people who are in the path of the trolley in the "Trolley Problem" case made famous by Judith Jarvis Thomson (1976; 1985). Furthermore, Thomson herself (2008) came to agree (...) that it would be wrong to throw the switch, just as it is wrong to push the person off the bridge to stop the trolley (1976; 1985). In changing her mind about this case, Thomson came to agree with Kant as well as with Philippa Foot (1967) who argued in her original paper that a negative duty not to harm one healthy patient outweighed a positive duty to give aid to five other patients by transplanting the healthy person's organs.

In this paper, we argue that solutions to normative challenges associated with autonomous driving, such as real-world trolley cases or distributions of risk in mundane driving situations, face the problem of reasonable pluralism: Reasonable pluralism refers to the fact that there exists a plurality of reasonable yet incompatible comprehensive moral doctrines within liberal democracies. The corresponding problem is that a politically acceptable solution cannot refer to only one of these comprehensive doctrines. Yet a politically adequate solution to the (...) normative challenges of autonomous driving need not come at the expense of an ethical solution, if it is based on moral beliefs that are (1) shared in an overlapping consensus and (2) systematized through public reason. Therefore, we argue that a Rawlsian justificatory framework is able to adequately address the normative challenges of autonomous driving and elaborate on how such a framework might be employed for this purpose.

This book argues that moral philosophy should be based on seven scientific principles of theory selection. It then argues that a new moral theory—Rightness as Fairness—satisfies those principles more successfully than existing theories. Chapter 1 explicates the seven principles of theory-selection, arguing that moral philosophy must conform to them to be truth-apt. Chapter 2 argues those principles jointly support founding moral philosophy in known facts of empirical moral psychology: specifically, our capacities for mental time-travel and modal imagination. Chapter 2 then (...) shows that these capacities present human decisionmakers with a problem of diachronic rationality that includes but generalizes beyond, L.A. Paul’s problem of transformative experience: a problem that I call “the problem of possible future selves.” Chapter 3 then argues that a new principle of rationality—the Categorical-Instrumental Imperative—is the only rational solution to this problem, as it requires our present and future selves to forge and uphold a recursive, bi-directional contract with each another given mutual recognition of the problem. Chapter 4 then shows that the Categorical-Instrumental Imperative has three identical formulations analogous but superior to Immanuel Kant’s various formulations of his ‘categorical imperative.’ Chapter 5 shows that these unified formulas jointly entail a particular test of moral principles: a Moral Original Position similar to John Rawls’ famous ‘original position’, but which avoids a variety of problems with Rawls' model. Chapter 6 then shows that the Moral Original Position generates Four Principles of Fairness, which can then be combined into a single principle of moral rightness: Rightness as Fairness. This new conception of rightness is shown to reconcile four dominant moral frameworks (deontology, consequentialism, virtue ethics, and contractualism), as well as entail a new method of moral decisionmaking for applied ethics: a method of “principled fair negotiation” according to which applied ethical issues cannot be wholly resolved through principled debate, but must instead be resolved by actual negotiation and compromise. This method is then argued to generate novel, nuanced analyses of a variety of applied moral issues, including trolley cases, torture, and the ethical treatment of nonhuman animals. Chapter 7 then shows that Rightness as Fairness reconciles three leading political frameworks—libertarianism, egalitarianism, and communitarianism—showing how all three embody legitimate moral ideals that can, and should, be fairly negotiated against each other to settle the scope, and nature, of domestic, international, and global justice on an ongoing, iterated basis. Finally, Chapter 8 argues that Rightness as Fairness satisfies all seven of the principles of theory-selected defended in Chapter 1 more successfully than rival theories. (shrink)

The essential idea of Leibniz’s Theodicy was little understood in his time but has become one of the organizing themes of modern mathematics. There are many phenomena that are possible locally but for purely mathematical reasons impossible globally. For example, it is possible to build a spiral staircase that is rising at any given point, but it is impossible to build one that is rising at all points and comes back to where it started. The necessity is mathematically provable, so (...) not subject to exception by divine power. Leibniz’s Theodicy argues that God could improve the universe locally in many ways, but not globally. This paper defends Leibniz, giving positive reasons for believing that there are so many necessary interconnections between goods and evils that God is faced with a choice like the classic Trolley case, where all of the scenarios that could be chosen upfront contain evils, but some more than others. Local changes for the better seem easy to imagine, but a proper understanding of global constraints undermines the initial impression that they can be done without global cost. The paper concludes by explaining how the context of the Leibnizian argument makes it reasonable to pursue the issue of whether there are no worlds better than this one. (shrink)

Experimental ethicists investigate traditional ethical questions with non-traditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be (...) classified according to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda. (shrink)

Since its inception, the trolley problem has sparked a rich debate both within and beyond moral philosophy. Often used as a primer for students to begin thinking about moral intuitions as well as how to distinguish between different forms of moral reasoning, the trolley problem is not without its uses in very practical, applied field like engineering. Often thought of as unrealistic by technically-oriented engineers, trolley cases in fact, help us to think about moral responsibility in (...) a high tech world. This chapter explores the usefulness of trolley-like thinking within the realm of responsible innovation and discusses how despite the inherent issues with trolley scenarios, they remain nonetheless an indispensable tool for helping us to explore ways to maximize our moral responsibility in innovation.

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.

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.

Consider three cases: -/- Turn: A trolley is about to kill five innocent strangers. You can turn the trolley onto me, saving the five and killing me. -/- Hurl: A trolley is about to kill five innocent strangers. You can hurl me at the trolley, saving the five and paralyzing me. -/- TurnHurl: A trolley is about to kill five innocent strangers. You can turn the trolley onto me, saving the five and killing (...) me. You can instead hurl me at the trolley, saving the five and paralyzing me. -/- Most find the following four claims intuitively plausible: -/- (1) It is permissible to turn the trolley onto me in Turn. (2) It is impermissible to hurl me at the trolley in Hurl. (3) It is impermissible to turn the trolley onto me in TurnHurl. (4) It is permissible to hurl me at the trolley in TurnHurl. -/- But how does turning go from permissible to impermissible, and hurling from impermissible to permissible, when both alternatives are available? I argue that such “secondary permissibility” claims are explained by contrastive consent. Even if I do not consent to being harmed, it is likely I’ll consent to being hurled at the trolley rather than being turned onto. (shrink)

In the case of AI, automated systems are making increasingly complex decisions with significant ethical implications, raising questions about who is responsible for decisions made by AI and how to ensure that these decisions align with society's ethical and moral values, both in India and the West. Jonathan Haidt has conducted research on moral and ethical decision-making. Today, solving problems like decision-making in autonomous vehicles can draw on the literature of the trolley dilemma in that it illustrates the complexity (...) of ethical decisions faced in emergency situations, as well as the moral implications of the decisions made. However, a series of moral principles must be understood and cited to avoid insufficient mechanistic explanations. Here we present a compilation of ethical positions both in India and the West.

Sacrificial dilemmas such as the trolley problem play an important role in experimental philosophy (x-phi). But it is increasingly argued that, since we are not likely to encounter runaway trolleys in our daily life, the usefulness of such thought experiments for understanding moral judgments in more ecologically valid contexts may be limited. However, similar sacrificial dilemmas are experienced in real life by animal research decision makers. As part of their job, they must make decisions about the suffering, and often (...) the death, of many non-human animals. For this reason, a context-specific investigation of so-called “3R dilemmas” (i.e., dilemmas where there is a conflict between the principles of replacement, reduction, and refinement of the use of animals in research) is essential to improve the situation of both non-human animals and human stakeholders. An approach well suited for such investigation is experimental philosophical bioethics (“bioxphi”), which draws on methods similar to x-phi to probe more realistic, practical scenarios with an eye to informing normative debates and ethical policy. In this article, we argue for a need to investigate 3R dilemmas among professional decision-makers using the tools of bioxphi. In a first step, we define 3R dilemmas and discuss previous investigations of professionals’ attitudes in such cases. In a second step, we show how bioxphi is a promising method to investigate the whys and hows of professional decision-making in 3R dilemmas. In a last step, we provide a bioxphi template for 3R dilemmas, give recommendations on its use, explore the normative relevance of data collected by such means, and discuss important limitations.

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 Bomber and Strategic Bomber which dominates this debate is underdetermined in three crucial respects: (1) the non-psychological worlds of Terror Bomber and Strategic Bomber; (2) the psychologies of Terror Bomber and Strategic Bomber; and (3) the structure of the thought-experiment, especially in relation to its similarity with the Trolley Problem. (1) If the (...) two worlds are not identical, then it may be these differences between the two worlds and not the Doctrine of Double Effect to explain the moral difference; (2a) 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; (2b) 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. Finally, (3) the Strategic Bomber scenario could also be constructed so as to be structurally equivalent to the Fat Man scenario in the Trolley Problem: but then the Doctrine of Double Effect would give different answers to two symmetrical cases.

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)

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.

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)

We aim to generate a dilemma for virtual reality-based research that we motivate through an extended case study of Judith Thomson’s (1985) Bridge variant of the trolley problem. Though the problem we generate applies more broadly than the Bridge problem, we believe it makes a good exemplar of the kind of case we believe is problematic. First, we argue that simulations of these thought experiments run into a practicality horn that makes it practically impossible to produce them. These problems (...) revolve around concepts that we call “perspectival fidelity”and “context realism.” Moral dilemmas that include features present in the Bridge variant will, as a result, be practically impossible to simulate. We also argue that, should we be wrong about the practical impossibility of creating a VR simulation of Bridge, such a simulation must face an ethical horn which renders these simulations ethically impermissible to develop or use. For these reasons, we argue that it is virtually impossible to simulate the bridge problem (and other thought experiments with similar features) both practically and ethically in VR. (shrink)

This dissertation compares the notions of homo rationalis in Philosophy and homo oeconomicus in Economics. Particularly, in Part I, we claim that both notions are close methodological substitutes. Accordingly, we show that the constraints involved in the notion of economic rationality apply to the philosophical notion of rationality. On these premises, we explore the links between the notions of Kantian and Humean rationality in Philosophy and the constructivist and ecological approaches to rationality in economics, respectively. Particularly, we show that the (...) constraints involved in both approaches to rationality in economics apply to the notions of Kantian and Humean rationality. That is why we introduce the notion of minimal global rationality. In a nutshell, the latter links one’s rationality to one’s ability to make good use of their cognitive apparatus to process contextual variables. On this basis, in Part II, we present two empirical tests showing that minimal global rationality is at work in philosophical experiments because systematic manipulations of contextual variables predictably affect philosophical judgment in the Trolley Problem and in some Knobe-like vignettes. In the first case, the manipulation of the information provided to subjects predictably causes inconsistent judgments. More precisely, subjects’ response to information shocks predictably causes them to issue inconsistent judgments. Instead, in the second case, our experimental results reveal that the Knobe Effect activates only if the perpetrator of an action is likely to be perceived as evil and unfriendly. Besides, when the Knobe-like vignettes include probabilistic outcomes, the Knobe Effect does not activate or is reduced in magnitude. For these reasons, we maintain that the availability heuristic bias arguably affects one’s judgment in Knobe-like experiment settings. Eventually, in Part III, we survey the general implications of the findings presented in Part II. First and foremost, we show that when manned social media algorithms produce wide-ranging availability cascades, agents predictably respond to those cascades by herding around biased claims. Interestingly, we find that the exposure to similarly redundant online content makes new social groups emerge unhindered. That is why populists and conspiracy theorists obtain such a large follow-up online. Secondly, we find that manned social media algorithms can exploit the flaws of minimal global rationality at a faster pace than humans. Yet, given that latter algorithms cannot do so on their own, we argue that the Turing Test is still an open game. Specifically, we argue so because state-of-the-art technology can request a service to be supplied (e.g., Google Duplex) but cannot operate direct sales. This constraint of state-of-the-art technology is linked to its inability to exploit the flaws of global minimal rationality as well as humans can. Importantly, we show that if algorithms were able to do so, the involved sociopolitical risk would be high. Therefore, we argue that only some form of regulation over state-of-the-art technology can prevent and reduce such sociopolitical risks. -/- In case you want a copy of this dissertation, please email me.

While autonomous vehicles (AVs) are not designed to harm people, harming people is an inevitable by-product of their operation. How are AVs to deal ethically with situations where harming people is inevitable? Rather than focus on the much-discussed question of what choices AVs should make, we can also ask the much less discussed question of who gets to decide what AVs should do in such cases. Here there are two key options: AVs with a personal ethics setting (PES) or (...) an “ethical knob” that end users can control or AVs with a mandatory ethics setting (MES) that end users cannot control. Which option, a PES or an MES, is best and why? This chapter argues, by drawing on the choice architecture literature, in favor of a hybrid view that requires mandated default choice settings while allowing for limited end user control. (shrink)

The central challenge of “machine ethics” is to build autonomous machine agents that act morally rightly. But how can we build autonomous machine agents that act morally rightly, given reasonable disputes over what is right and wrong in particular cases? In this chapter, I argue that Immanuel Kant’s political philosophy can provide an important part of the answer.

In this article Judith Jarvis Thomson's Good Samaritan Argument in defense of abortion in the case of rape is defended from two objections: the Kill vs. Let Die Objection, and the Intend to Kill vs. Merely Foresee Death Objection. The article concludes that these defenses do not defend Thomson from further objections from Peter Singer and David Oderberg.

Discussion of moral responsibility has traditionally centred around actions and the possibility of alternative actions. In this short paper I take a different approach and focus on choices rather than actions. I argue that a person is morally responsible directly for their choices and only indirectly for resulting actions. This subtle shift helps to clarify many issues such as moral luck, thwarted choice and coercion.

Many philosophers have thought that aggregates of small, broadly dispersed evils don’t pose the same sort of challenge to theism that horrendous evils like the Nazi Holocaust do. But there are interesting arguments that purport to show that large enough aggregates of small evils are morally and axiologically equivalent to horrendous evils. Herein lies an intriguing and overlooked strategy for defending theism. In short: small evils, or aggregates of such evils, don’t provide decisive evidence against theism; there’s no relevant difference (...) between horrendous evils and aggregates of small evils; hence horrendous evils must not provide decisive evidence against theism, either.

The word ‘extremist’ is often used pejoratively, but it’s not clear what, if anything, is wrong with extremism. My project is to give an account of moral extremism as a vice. It consists roughly in having moral convictions so intense that they cause a sort of moral tunnel vision, pushing salient competing considerations out of mind. We should be interested in moral extremism for several reasons: it’s consequential, it’s insidious – we don’t expect immorality to arise from excessive devotion to (...) morality – and it’s yet to attract much philosophical attention. I give several examples of moral extremism from history and explore their social-political implications. I also consider how we should evaluate people who miss the mark, being either too extreme in the service of a good cause or inconsistent with their righteous convictions. I compare John Brown and John Quincy Adams, who fell on either side of this spectrum, as examples. (shrink)

I analyse the relationship between the Doctrine of Double Effect and the Trolley Problem: the former offers a solution for the latter only on the premise that killing the one in Bystander at the Switch is permissible. Here I offer both empirical and theoretical arguments against the permissibility of killing the one: firstly, I present data from my own empirical studies according to which the intuition that killing the one is permissible is neither widespread nor stable; secondly, I defend (...) a normative principle according to which killing the one in Bystander at the Switch is not permissible. In conclusion, there just is no trolley problem. (shrink)

In this paper, the ethical and spiritual aspects of the trolley problem are discussed in connection with the dropping of atomic bombs on Hiroshima and Nagasaki. First, I show that the dropping of atomic bombs was a typical example of the events that contained the logic of the trolley problems in their decision-making processes and justifications. Second, I discuss five aspects of “the problem of the trolley problem;” that is to say, “Rarity,” “Inevitability,” “Safety Zone,” “Possibility of (...) Becoming a Victim,” and “Lack of Perspective of the Dead Victims Who Were Deprived of Freedom of Choice,” in detail. Third, I argue that those who talk about the trolley problem are automatically placed in the sphere of the expectation of response on the spiritual level. I hope that my contribution will shed light on the trolley problem from a very different angle, which has not been made by our fellow philosophers. (shrink)

The trolley problem is one of the liveliest research frameworks in experimental ethics. In the last decade, social neuroscience and experimental moral psychology have gone beyond the studies with mere text-based hypothetical moral dilemmas. In this article, I present the rationale behind testing the actual behaviour in more realistic scenarios through Virtual Reality and summarize the body of evidence raised by the experiments with virtual trolley scenarios. Then, I approach the argument of Ramirez and LaBarge (2020), who claim (...) that the virtual simulation of the Footbridge version of the trolley dilemma is an unethical research practice, and I raise some objections to it. Finally, I provide some reflections about the means and ends of trolley-like scenarios and other sacrificial dilemmas in experimental ethics. (shrink)

Trolley problems have been used in the development of moral theory and the psychological study of moral judgments and behavior. Most of this research has focused on people from the West, with implicit assumptions that moral intuitions should generalize and that moral psychology is universal. However, cultural differences may be associated with differences in moral judgments and behavior. We operationalized a trolley problem in the laboratory, with economic incentives and real-life consequences, and compared British and Chinese samples on (...) moral behavior and judgment. We found that Chinese participants were less willing to sacrifice one person to save five others, and less likely to consider such an action to be right. In a second study using three scenarios, including the standard scenario where lives are threatened by an on-coming train, fewer Chinese than British participants were willing to take action and sacrifice one to save five, and this cultural difference was more pronounced when the consequences were less severe than death.

There is a long-standing debate in philosophy about whether it is morally permissible to harm one person in order to prevent a greater harm to others and, if not, what is the moral principle underlying the prohibition. Hypothetical moral dilemmas are used in order to probe moral intuitions. Philosophers use them to achieve a reflective equilibrium between intuitions and principles, psychologists to investigate moral decision-making processes. In the dilemmas, the harms that are traded off are almost always deaths. However, the (...) moral principles and psychological processes are supposed to be broader than this, encompassing harms other than death. Further, if the standard pattern of intuitions is preserved in the domain of economic harm, then that would open up the possibility of studying behavior in trolley problems using the tools of experimental economics. We report the results of two studies designed to test whether the standard patterns of intuitions are preserved when the domain and severity of harm are varied. Our findings show that the difference in moral intuitions between bystander and footbridge scenarios is replicated across different domains and levels of physical and non-physical harm, including economic harms.

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)

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 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.

One challenge for moderate invariantists is to explain why we tend to deny knowledge to subjects in high stakes when the target propositions seem to be inappropriate premises for practical reasoning. According to an account suggested by Williamson, our intuitive judgments are erroneous due to an alleged failure to acknowledge the distinction between first-order and higher-order knowledge: the high-stakes subject lacks the latter but possesses the former. In this paper, I provide three objections to Williamson’s account: i) his account delivers (...) counterintuitive verdicts about what it is appropriate for a high-stakes subject to do; ii) the high-stakes subject doesn’t need iterated knowledge in order to be regarded as appropriately relying on the relevant proposition in practical reasoning; iii) Williamson’s account doesn’t provide a good explanation of why the high-stakes subject would be blameworthy if she were relying on the relevant proposition in her practical reasoning.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some decades later, (...) Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

In 1947, the U.S. Secretary of State, George C. Marshall announced that the USA would provide development aid to help the recovery and reconstruction of the economies of Europe, which was widely known as the ‘Marshall Plan’. In Italy, this plan generated a resurgence of modern industrialization and remodeled Italian Industry based on American models of production. As the result of these transnational transfers, the systemic approach known as Fordism largely succeeded and allowed some Italian firms such as Fiat to (...) flourish. During this period, Detroit and Turin, homes to the most powerful automobile corporations of the twentieth century, became intertwined in a web of common features such as industrial concentration, mass flows of immigrations, uneven urban sprawl, radical iconography and inner-city decay, which characterized Fordism in both cities. In the crucial decades of the postwar expansion of the automobile industries, both cities were hubs of labor battles and social movements. However, after the radical decline in their industries as previous auto cities, they experienced the radical shift toward post-Fordist urbanization and production of political urbanism. This research responds to the recent interest for a comparative (re)turn in urban studies by suggesting the conceptual theoretical baseline for the proposed comparative framework in post-Fordist cities. In better words, it develops a “theory” on the challenges of comparative urbanism in post-Fordist cities. (shrink)

In recent years, the significance of industrial heritage has seemed to become a growing trend in international heritage studies. Concerning their attributed values and the crucial needs for urban development, this branch of cultural heritage has been considered the important grid of cities. This has caused a great acceptance of adaptive reuse practices especially among developing countries which is a smart response to an ongoing debate to reach sustainable development. The flexibility of these buildings and sites seems an important criterion, (...) which can be improved through adaptive reuse practice. Therefore, this research aims to introduce the concept of flexibility in industrial heritage sites, evaluate its criteria among adaptive reuse practices, and make a comprehensive flexibility model for it. Indeed, the final goal is to determine the condition that based on the flexibility model, the adaptive reuse practice would be a proper way of encountering these sites. A historical-interpretation research method, analytical-description techniques, and questionnaire-based interviews are applied in this research. Results indicate that flexibility has genuinely been considered in this practice. Analysing flexibility techniques, this paper suggests a valuable framework to achieve the flexibility of industrial heritage as the presupposition of successful adaptive reuse in these sites.

Sostengo en este artículo que no somos utilitaristas consecuentes en todo momento, ni deontologistas dogmáticos irracionales, más bien, una mezcla de utilitarismo y deontologismo que depende de una serie de factores no descubiertos o explicados convincentemente tanto epigenéticos, evolutivos, como educacionales, axiológicos, psicológicos aprendidos, conscientes e inconscientes en la toma de decisiones. También argumento que no es lo mismo toma de decisión, que construcción del juicio moral. El juicio moral no siempre conduce a la toma de decisión. Se puede tener (...) un juicio, pero no necesariamente actuar en consecuencia. / I argue in this article that we are not consistent utilitarians at all times, nor irrational dogmatic deontologists, rather, a mixture of utilitarianism and deontologism that depends on a series of factors undiscovered or convincingly explained both epigenetic, evolutionary, as educational, axiological, psychological learned, conscious and unconscious in decision making. I also argue that decision making is not the same as constructing moral judgment. The second does not always lead to the first. I can have a trial, but not necessarily act accordingly. (shrink)

There is now a burgeoning literature on evolutionary debunking arguments (EDAs) against moral beliefs, but perhaps surprisingly, a relatively small literature on EDAs against religious beliefs. There is an even smaller literature comparing the two. This essay aims to further the investigation of how the two sorts of arguments compare with each other. To begin with, I shall offer some remarks on how to best formulate these arguments, focusing on four different formulations that one can discern in the literature and (...) that can be applied to both sorts of beliefs. I shall then go on to make a series of comparisons regarding the relative vulnerabilities of moral beliefs and theistic religious beliefs to these four arguments, suggesting that there are a number of respects in which theistic religious beliefs are somewhat less liable than moral beliefs to be undercut by EDAs.

Frankfurt cases are purported counterexamples to the Principle of Alternative Possibilities, which implies that we are not morally responsible for unavoidable actions. A major permutation of the counterexample strategy features buffered alternatives; this permutation is designed to overcome an influential defense of the Principle of Alternative Possibilities. Here we defend the buffering strategy against two recent objections, both of which stress the timing of an agent’s decision. We argue that attributions of moral responsibility aren’t time-sensitive in the way the (...) objectors suppose. We then turn to the crucial question of when an action is relevantly avoidable—when, in the parlance of the literature, an alternative possibility is robust. We call attention to two plausible tests for robustness that merit further consideration, showing that the agents in buffered Frankfurt cases don’t pass these tests, despite being morally responsible for their actions.

There is an ongoing methodological debate in philosophy of science concerning the use of case studies as evidence for and/or against theories about science. In this paper, I aim to make a contribution to this debate by taking an empirical approach. I present the results of a systematic survey of the PhilSci-Archive, which suggest that a sizeable proportion of papers in philosophy of science contain appeals to case studies, as indicated by the occurrence of the indicator words “case study” and/or (...) “case studies.” These results are confirmed by data mined from the JSTOR database on research articles published in leading journals in the field: Philosophy of Science, the British Journal for the Philosophy of Science (BJPS), and the Journal for General Philosophy of Science (JGPS), as well as the Proceedings of the Biennial Meeting of the Philosophy of Science Association (PSA). The data also show upward trends in appeals to case studies in articles published in Philosophy of Science, the BJPS, and the JGPS. The empirical work I have done for this paper provides philosophers of science who are wary of the use of case studies as evidence for and/or against theories about science with a way to do philosophy of science that is informed by data rather than case studies.

Steven Hales and Jennifer Johnson—building off their (2014) work as well as Hales (2015, 2016)—have recently conducted two studies in Philosophical Psychology (2018) that show that there is a relationship between optimism and folk assessments of luck. Hales and Johnson use these results to argue that there is no such thing as luck. Instead, they claim that the concept is highly subjective and a cognitive illusion and that what we are in need of is an error theory. After reviewing Hales (...) and Johnson’s position, I levy four objections against their view. First, they ignore the fact that luck involves a chanciness condition. Second, their standards for what it means to be a useful philosophical theory are too high. Third, their view ignores the fact that there are various accounts of value in the literature and assumes a kind of relativism that few people would be willing to accept. Lastly, their error theory is not supported by the empirical evidence. Because of these problems, Hales and Johnson’s argument is not a serious threat to extant accounts of luck. (shrink)
