Animalists accuse the advocates of psychological approaches of identity of having to suffer a Problem of Too Many Thinkers. Eric Olson, for instance, is an animalist who maintains that if the person is spatially coincident but numerically distinct from the animal, then provided that the person can use its brain to think, so too can the physically indistinguishable animal. However, not all defenders of psychological views of identity assume the spatial coincidence of the person and the animal. Jeff McMahan and (...) lately Derek Parfit claim we are roughly brain-size, composed of just those parts of the human animal that directly produce thought. They claim to avoid the Problem of Too Many Thinkers because it is the brain-sized person who truly thinks, while the animal thinks only in a derivative sense in virtue of having a thinking proper part. Waiting in the wings are some dualists who claim that all materialist accounts fail to avoid the Problem of Too Many Thinkers. One such dualist, Dean Zimmerman, insists that wherever there is an ordinary material thing like a brain, there is also a mass with distinct persistence conditions and thus the threat of two material thinkers. Zimmerman contends that only positing an immaterial thinker can avoid the problem. (shrink)

Cet essai va aborder la question d'éthique normative de savoir où doit s'arrêter notre considération morale. On peut en effet se demander si nous n'avons pas des obligations morales en dehors de celles que nous avons à l'égard des représentants de l'espèce humaine que nous côtoyons. Est-il possible d'envisager des obligations à l'égard des animaux ou des générations futures? C'est une question qui fait débat dans la philosophie morale depuis l'antiquité – pour les animaux du moins – mais qui a (...) connu un regain d'intérêt depuis une quarantaine d'années, principalement dans la philosophie anglo-saxonne, et qui a parfois été appelée problème du périmètre. Nous allons nous intéresser plus particulièrement au statut moral des animaux : quelle considération morale leur doit-on? Doivent-ils être inclus dans le périmètre ou rester au-delà? (shrink)

This thesis will utilise the literature on the distinction between doing harm and allowing harm to develop a novel system of moral sequencing that can be applied to general moral problems to decide if, when, and how an agent should intervene to prevent harm from occurring to another agent. Off the back of this discussion, this thesis will offer a way of determining the responsibility of certain agents for their actions within a moral sequence. These motivations will be at the (...) centre of the discussions in this thesis and will be accomplished by ultimately updating the system of moral sequencing so that it makes sense of practical cases of inner-agent change, which itself provides a justification for intervening earlier, and potentially diminishing the responsibility for agents who have experienced an inner-agent change, in a moral sequence.

The rich resources of the Four-Dimensional metaphysics have been brought to bear upon many traditional philosophical problems in recent years. Alas, the implications of Four-Dimensionalism for bioethics have gone largely unexplored. Hud Hudson is the rare exception. Relying upon a Four- Dimensional metaphysics of temporal parts and a belief in unrestricted composition, he argues that there is little reason to identify the perduring human embryonic animal and the perduring human person. He makes the intriguing claim that if abortion is wrong, (...) then it is not because the human animal within its mother’s womb is a person. This he rightly claims “is a very significant result” for “an overwhelming amount of the literature on abortion and infanticide (as well as much of the public debate on these topics) seems to turn on the question of whether or not the human fetus is a person.” [3, p. 153].

Here I develop an account of our persistence that accommodates each of the following compelling intuitions: (i) that we are animals, (ii) that we existed prior to the onset of whatever psychological capacities are necessary for personhood, and we can continue to exist with the loss of those and other psychological capacities, (iii) that with suitable psychological continuity, the person goes with the brain/cerebrum in remnant person and brain/cerebrum transplant cases, and (iv) that it is possible for us to survive (...) gradual large-scale replacement of organic with inorganic parts. With the help of a couple of recent “hybrid” animalist accounts I develop an analysis of our persistence that entails (ii)–(iv) while being consistent with (i). (shrink)

I introduce here a special issue dedicated to the British philosopher Jonathan Glover. Recognized as an important figure in applied ethics in the Anglo-Saxon world, Glover does not yet enjoyed the same reputation in the French-speaking world. In 2017, forty years after the original publication of Causing Death and Saving Lives, I published a French translation of the same book, entitled Questions de vie ou de mort. In this editorial, I begin by recalling the reasons why Glover considered it necessary (...) in the 1960s to give ethics a more "applied" character. Then I present in broad terms the ethics of "making people die" defended by Glover, resolutely pluralist, and not strictly utilitarian as some may have thought. Finally, I introduce the contributions to this special issue, as well as the three interviews I conducted with Jonathan Glover, Peter Singer and Jeff McMahan. (shrink)

We have structured our response according to five questions arising from the commentaries: (i) What is sentience? (ii) Is sentience a necessary or sufficient condition for moral standing? (iii) What methods should guide comparative cognitive research in general, and specifically in studying invertebrates? (iv) How should we balance scientific uncertainty and moral risk? (v) What practical strategies can help reduce biases and morally dismissive attitudes toward invertebrates?

This article reconstructs the theoretical premises of Tom Regan’s animal ethics, the American philosopher recently disappeared who has given a fundamental contribu-tion to this area of practical ethics, by developing a theory of rights based on the extension to all subjects-of-a-life of Kantian notions such as inherent value and respect. Regan’s theory still remains the most rigorous foundation of an animal ethics alternative to the utilitarian approach of Peter Singer, but it is not without unresolved problems or not entirely satisfactory (...) solutions. To remedy some of them, in the final part the author tries to insert into the Reganian theoretical framework elements of gradualism. (shrink)

Most philosophical accounts of human rights accept that all persons have human rights. Typically, ‘personhood’ is understood as unitary and binary. It is unitary because there is generally supposed to be a single threshold property required for personhood. It is binary because it is all-or-nothing: you are either a person or you are not. A difficulty with binary views is that there will typically be subjects, like children and those with dementia, who do not meet the threshold, and so who (...) are not persons with human rights, on these accounts. It is consequently unclear how we ought to treat these subjects. This is the problem of marginal cases. I argue that we cannot resolve the problem of marginal cases if we accept a unitary, binary view of personhood. Instead, I develop a new non-binary personhood account of human rights, and defend two main claims. First, there are many, scalar properties, the having of which are conducive to personhood. Second, different subjects have different human rights depending on which of these properties they have, and what threats apply to them. On my view, and contra most existing accounts, most marginal cases have some degree of personhood and are entitled to some human rights. (shrink)

This thesis focuses on what I call the question of exclusion. This question, I argue, is one that poses serious challenges to social contract approaches to justice and political legitimacy. In an intuitive way, the exclusion of some individuals seems to be a corollary of the social contractualist approach, which ascribes justice or legitimacy to a social arrangement insofar as it can be regarded as the product of the (actual – expressed or tacit – or hypothetical) consent of specified parties. (...) Consequently, this approach excludes those whose consent is not required in order to view an arrangement as legitimate or just. Given the enormous and continuing influence of John Rawls’s social contract theory, I take the Rawlsian view as my primary focus, concentrating on the way in which the question of exclusion raises challenges for Rawlsian contractualism. According to Rawls’s theory, those who participate in the hypothetical contract and to whom political power ought to be justifiable are reasonable and rational. They are reasonable in the sense that they understand and are willing to comply with the requirements of justice and they are rational in that they have the capacity to form, revise, and pursue a conception of the good. This gives rise to two categories of exclusion. In the first part of the thesis, I examine the exclusion of those who will develop the two moral powers sufficiently only if those who are represented in the social contract act (or refrain from acting) in certain ways. This category includes children, foetuses, and unreasonable citizens. Intuitively, justice issues in requirements in at least some of these cases, but it is hard to make sense of this on the Rawlsian approach. In the second part of the thesis, I address the question of exclusion regarding those who will never develop the two moral powers to the requisite degree, such as individuals with severe cognitive disabilities and non-human animals. Again, intuitively, justice issues in requirements here, but their justification is not clear on the contractualist approach. My conclusion is threefold. First, I argue that the problems the question of exclusion poses cannot be addressed by a single solution. Second, I safeguard Rawlsian contractualism by showing how each problem can be resolved. Third, I offer policy-prescriptions on a number of issues, such as education, abortion, and the criminal justice system. (shrink)

Animal welfare is a concept that plays a role within both our moral deliberations and the relevant areas of science. The study of animal welfare has impacts on decisions made by legislators, producers and consumers with regards to housing and treatment of animals. Our ethical deliberations in these domains need to consider our impact on animals, and the study of animal welfare provides the information that allows us to make informed decisions. This thesis focusses on taking a philosophical perspective to (...) answer the question of how we can measure the welfare of animals. Animal welfare science is an applied area of biology, aimed at measuring animal welfare. Although philosophy of animal ethics is common, philosophy focussing on animal welfare science is rare. Despite this lack, there are definitely many ways in which philosophical methods can be used to analyse the methodologies and concepts used in this science. One of the aims of the work in this thesis is to remedy this lack of attention in animal welfare. Animal welfare science is a strong emerging discipline, but there is the need for conceptual and methodological clarity and sophistication in this science if it is to play the relevant informative role for our practical and ethical decision-making. There is thus is a strong role here for philosophical analysis for this purpose. The central aim of this thesis is to provide an account of how we can measure subjective animal welfare, addressing some of the potential problems that may arise in this particular scientific endeavour. The two questions I will be answering are: what is animal welfare, and how do we measure it? Part One of the thesis looks at the subjective concept of animal welfare and its applications. In it, I argue for a subjective welfare view - that animal welfare should be understood as the subjective experience of individuals over their lifetimes - and look at how the subjective welfare concept informs our ethical decision-making in two different cases in applied animal ethics. Part Two of the thesis looks more closely at the scientific role of welfare. Understanding welfare subjectively creates unique measurement problems, due to the necessarily private nature of mental states and here I address a few of these problems, including whether subjective experience is measurable, how we might validate indicators of hidden target variables such as welfare, how we can make welfare comparisons between individual animals and how we might compare or integrate the different types of experience that make up welfare. I end with a discussion of the implications of all these problems and solutions for the practice of welfare science, and indicate useful future directions for research. (shrink)

According to the procreation asymmetry there is no moral reason to create a new and foreseeably happy person just because this person will be happy, but there is however a moral reason against creating a new and foreseeably unhappy person just because this person will be unhappy. A common way to defend this conjunction of claims is by employing a so-called existence-requirement, according to which the happiness of a given person p in a world w depends on it being possible (...) to understand p as an existing person in w. The aim of this paper is to consider whether this existence-requirement strategy is compatible with other intuitions and convictions held in normative moral theory and populations ethics. This aim will be achieved by considering whether the existence-requirement strategy is compatible with three plausible desiderata for a solution to the procreation asymmetry. Although some solutions to some potential incompatibilities are suggested, the thesis that will be argued for is that every instance of the existence-requirement strategy is incompatible with at least one of the relevant desiderata. Where the common denominating incompatibility for all instances of the existence-requirement strategy is to be found in an inability to be sufficiently action-guiding. (shrink)

I present and defend (1) an account of ethical judgments as judgments about our reasons to feel specific motivationally laden attitudes, (2) an account of what an agent should do in terms of what would achieve ends that she has reason to be motivated to pursue, and (3) an account of an agent’s reasons for motivation (and thus action) in terms of the prescriptions of the most fundamental principles that guide her deliberations. Using these accounts, I explain the connection between (...) ethics and reasons for action, how ethical judgments are both descriptive and intrinsically motivating, and how ethical facts arise from facts about agents’ deliberations.

This paper attempts to reconcile two apparently opposed ways of thinking about the imagination and its relationship to literature, one which casts it as essentially concerned with fiction-making and the other with culture-making. The literary imagination’s power to create fictions is what gives it its most obvious claim to “autonomy”, as Kant would have it: its freedom to venture out in often wild and spectacular excess of reality. The argument of this paper is that we can locate the literary imagination’s (...) complementary power of cultural articulation in this fictional activity. The suggestion is that we should conceive of the literary imagination as expressing its interests in culture not mimetically but by producing a certain kind of meaning. This meaning is irreducibly narratological, and understanding it helps us to see the role of narrative in bringing into harmony the literary imagination’s interests in both the imaginary and the real.

What role should sentient animals play in the current debate on enhancement? The question covers several different philosophical fronts that demand urgent global ethical analysis. This touches issues that go from prohibition, permissivity or obligation that should characterize the new biotechnologies oriented to the enhancement of individuals, to the debate surrounding the moral rights of animals. Furthermore, the difficulty arises not only from the controversial moral categories involved, but also from the very extent of the objective proposed. However, this also (...) gives rise to the pertinence of the above-mentioned question posed at the outset: on the one hand, the need for consistency in an eminently biased debate, and on the other the need to justify the proposal in which all sentient individuals are legitimate protagonists without this necessarily leading to implausible scenarios.

In the third edition of ‘Practical Ethics’ (2011), Peter Singer reexamines the so-called “replaceability argument,” according to which merely sentient beings, as opposed to persons (self-conscious and with a robust sense of time), are replaceable—it is in principle permissible to kill them provided that they live pleasant lives that they would not have had otherwise and that they be replaced by equally happy beings. On this view, existence is a benefit and death is not a harm. Singer’s challenge is to (...) avoid (i) the replaceability of persons while preserving the replaceability of merely sentient beings, (ii) the implication that parents are morally required to procreate if they can have happy children, and (iii) to do avoid these implications without having the proposed solution (the “debit view” of preferences) imply negative utilitarianism, or the conclusion that a nonsentient universe is better than any sentient universe. I review Singer’s changing views since 1975 and I argue that his attempt to avoid the replaceability of persons fails: either both non-persons and persons are replaceable or neither are. Singer can only avoid this conclusion by appealing to controversial metaethical claims (attitude-independent moral objectivism) and/or giving up on essential features of utilitarianism. (shrink)

This article examines and rejects the view that nonhuman animals cannot be recipients of justice, and argues that the main reasons in favor of universal human rights and global justice also apply in the case of the international protection of the interests of nonhuman animals. In any plausible theory of wellbeing, sentience matters; mere species membership or the place where an animal is born does not. This does not merely entail that regulations of the use of animals aimed at reducing (...) their suffering should be implemented. It actually supports the end of such use, as well as other positive steps to provide help and to promote what is good not only for domesticated animals, but also for those living in the wild. Another reason to bring the protection of animals' interests into the international arena is that it is at this level that numerous animal exploitation industries enjoy the protection of different agreements and institutions. It does not follow from this that changing international law should be animal advocates' first priority, but it does follow that they should conduct their work internationally and not limit it to their own countries.

The Asymmetry in procreative ethics consists of two claims. The first is that it is morally wrong to bring into existence a child who will have an abjectly miserable life; the second is that it is permissible not to bring into existence a child who will enjoy a very happy life. In this paper, I distinguish between two variations of the Asymmetry. The first is the Abstract Asymmetry, the idealized variation of the Asymmetry that many philosophers have been trying to (...) solve. The second is the Real-World Asymmetry, a non-idealized variation that applies explicitly to cases of ordinary human reproduction. I argue that the Real-World Asymmetry can be defended by properly acknowledging the general wrongness of causing someone else to suffer, the limits of what morality can reasonably demand of us, and the significance of respecting women’s autonomy. I then argue that the Abstract Asymmetry is indefensible. (shrink)

A number of areas of biology raise questions about what is of value in the natural environment and how we ought to behave towards it: conservation biology, environmental science, and ecology, to name a few. Based on my experience teaching students from these and similar majors, I argue that the field of environmental ethics has much to teach these students. They come to me with pent-up questions and a feeling that more is needed to fully engage in their subjects, and (...) I believe some exposure to environmental ethics can help focus their interests and goals. I identify three primary areas in which environmental ethics can con- tribute to their education. The first is an examination of who (or what) should be considered to be part of our moral community (i.e., the community to whom we owe direct duties). Is it humans only? Or does it include all sentient life? Or all life? Or ecosystems considered holistically? Often, readings implicitly assume one or more of these answers; the goal is to make the student more sensitive to these implicit claims and to get them to think about the different reasons that support them. The second area, related to the first, is the application of the different answers concerning the extent of the ethical community to real environmental issues and problems. Students need to be aware of how the different answers concerning the moral community can imply conflicting answers for how we should act in certain cases and to think about ways to move toward conflict resolution. The third area in which environmental ethics can contribute is a more conceptual one, focusing on central concepts such as biodiversity, sustainability, species, and ecosystems. Exploring and evaluating various meanings of these terms will make students more reflective and thoughtful citizens and biologists, sensitive to the implications that different conceptual choices make.

WHEN ONE ASSUMES, as I will, that death marks the irrevocable end to one’s existence, it is difficult to make sense of the idea that a person could be harmed or benefited by events that take place after her death. How could a posthumous event either enhance or diminish the welfare of the deceased, who no longer exists? Yet we find that many people have a prudential (i.e., self-interested) concern for what’s going to happen after their deaths.1 People are, for (...) instance, concerned that their reputations not be slandered, that their achievements not be undermined, and that their contributions not be forgotten, not even after their deaths. Of course, many philosophers would insist that such a concern for what’s going to happen after one’s death must be based on, or a remnant of, a false belief in an afterlife. I, however, will argue that even if death marks the unequivocal and permanent end to one’s existence, people have good reason to be prudentially concerned with what’s going to happen after their deaths, for, as I will show, a person’s welfare can indeed be affected by posthumous events.

Axiological egalitarianism claims that an outcome improves at least in some respect if the value it contains is more evenly distributed. In this paper I defend this form of egalitarianism and identify some of its corollaries. First, I consider and reject the levelling down objection. I then point out that egalitarianism casts doubt on the traditional view of the value of life in terms of maximization. Further, I argue that this theory also questions anthropocentric conceptions of value.

The vast advances in biometrics over the past several decades have brought with them a host of pressing concerns. Philosophical scrutiny has already been devoted to many of the relevant ethical and political issues, especially ones arising from matters of privacy, bias, and security in data collection. But philosophers have devoted surprisingly little attention to the relevant metaphysical issues, in particular, ones concerning matters of personal identity. This paper aims to take some initial steps to correct this oversight. After discussing (...) the philosophical problem of personal identity, the ways in which the notion of biometric identity connects with, or fails to connect with, the philosophical notion of personal identity is explored. Though there may be some good reasons to use biometric identity to track personal identity, it is contended that biometric identity is not the same thing as personal identity and thus that biometrics researchers should stop talking as if it were.

In this paper, I provide an analysis of Marya Schechtman's theory of personal identity defended in her book Staying Alive: Personal Identity, Practical Concerns, and the Unity of a Life.

Mikhalevich & Powell (2020) argue that it is wrong, both scientifically and morally, to dismiss the evidence for sentience in invertebrates. They do not offer any examples, however, of how their welfare should be considered or improved. We draw on animal welfare science to suggest some ways that would not be excessively demanding.

The article focuses on one of the identity-related practical concerns discussed in contemporary debate on personal identity, namely self-concern. The dominant view seems to be that people’s concern for their future selves is preconditioned by their ability to anticipate the experiences of their future selves and that, as a result, a psychological theory of personal identity is required to justify self-concern. I argue that self-concern in its most general form is not preconditioned by the possibility of anticipation. I provide examples (...) showing that people may legitimately be concerned for their future selves even if those selves are unconscious or dead, that is, in states that the people cannot anticipate. I contend that self-concern is not rooted in our desire to have positive experiences, but in our desire to live meaningful lives. Since the value of our lives can be influenced by events that only take place after we cease to exist, I further argue that certain posthumous states of affairs relevant to our lives can also be the legitimate target of an indirect sort of self-concern. Inspired by Marya Schechtman’s theories, I develop a form of the narrative theory of personal identity in the sense of characterization and show that narrative continuity can be both a source of meaning in a person’s life and a ground for the person’s self-concern. It turns out that the sort of identity that justifies non-anticipatory self-concern cannot be numerical identity, because it does not provide the persistence conditions of people. (shrink)

Common sense has that killing someone amounts to causing the death of someone. This makes killing a physical, biological, or, at best, metaphysical issue, and, as a consequence, the ethics of killing can be dealt with independently of the non-ethical issue of who the killer is. However, in this paper, we show that this is not the case. A physical/biological definition of death plus a metaphysical definition of causation does not exhaust the meaning of killing. Rather, the notion of killing (...) per se generally presumes a notion of default, which often involves ethical considerations. (shrink)

For hundreds of years, death had been defined by cardiopulmonary criteria. When heart and respiratory functions were permanently absent, doctors declared their patients dead. Three developments in intensive care medicine called into question these widely-accepted criteria, however: the advent of positive pressure ventilation and the promotion of cardiopulmonary resuscitation, both in the early 1950s, and the first successful heart transplantation in 1967. What had previously been diagnosed as the permanent absence of vital functions, suddenly became reversible. Not only could doctors (...) replace a defective heart with a functioning transplant; patients could also be kept oxygenated in the total absence of spontaneous respiratory function. The traditional boundaries between life and death became blurred. Patients for whom there was not the remotest possibility of regaining consciousness following massive brain damage continued to consume valuable medical resources. Moreover, their organs could not be procured for transplantation. Were those patients still alive or could the ventilators be switched off? A criterion suited to indicate a patient’s death despite the provision of external life support was needed. In 1968 an ad hoc committee of the Harvard Medical School published the first comprehensive definition of what would soon become the new clinical standard: brain death. The brain bears a special relation to other organs; it directs bodily functions without carrying them out. When the brain is destroyed, it was argued, this control mechanism is irreversibly dysfunctional, so that the organism becomes unable to maintain its vital functions, loses its somatic unity and, consequently, ceases to exist. This neurological criterion has been controversial ever since its introduction. Whether brain death is indeed death is what I shall be investigating in this thesis. I will be asking three main questions: What are we? Is brain death the death of an organism? Is brain death the death of a psychological being? The question of personal identity and the question of the appropriate definition of death are intimately related. Only when we have determined what kind of entity we essentially are can we specify what conditions must apply for this entity to persist or to cease to exist. I shall argue that we are essentially psychological beings, which entails that our death is distinct from the death of our organisms. Hence, we need two different criteria – one for the death of each entity. I shall try to establish whether brainstem death and whole-brain death correspond to the irreversible cessation of organismic functioning. I will then determine by which criterion the death of a psychological being can be diagnosed. (shrink)

The Moral Complexities of Eating Meat, Ben Bramble and Bob Fischer eds., Oxford University Press, 2015. (An open-access version of this article is available at the link below.) -/- Vegans who do not eat roadkill are immoral. Consider that the most common rationale for veganism is avoiding unnecessary harm to animals. It is a well-known fact that animals are killed in the cultivation of plant foods such as wheat, corn and soybeans. Mice, rabbits and other field creatures are routinely run (...) over by tractors or cut in two by harvesters. To buy commercial plant food therefore is to sustain the system responsible for these deaths. Road-killed animals, by contrast, are already dead, so the decision to consume them does not perpetuate a lethal process. A diet that consists entirely of plant food therefore will be responsible for a greater number of animal fatalities than a mostly-plant diet that also includes roadkill but no other meat. -/- So goes the argument of Donald Bruckner’s cheeky paper, “Strict Vegetarianism is Immoral,” a standout chapter of The Moral Complexities of Eating Meat. Anyone who follows the animal ethics literature will be familiar with defences of meat eating premised on a rejection of animal rights. Bruckner’s ingenious argument by contrast is premised on animals having rights. This captures something of the collection in general, which offers original moves and thought-provoking conclusions with impressive frequency. (shrink)

Em analogia com outras discriminações, como o racismo ou o sexismo, o especismo é concebido como uma forma de discriminação moral com base na espécie. Em grande medida, a discussão contemporânea sobre a importância moral dos animais surgiu e desenvolveu-se em torno da crítica e da defesa do especismo. Este artigo oferece uma visão da discussão filosófica contemporânea sobre o especismo. Após uma breve introdução, apresenta-se uma definição de especismo e caracterizam-se vários tipos de especismo, sendo o Antropocentrismo o mais (...) relevante. Depois, expõe-se um argumento proeminente contra o Antropocentrismo: o argumento dos casos marginais. Por fim, algumas posições antropocêntricas são criticamente discutidas. (shrink)

Common principles for resource allocation in health care can prioritize the alleviation of small health burdens over lifesaving treatment. I argue that there is some evidence that these principles are at odds with a sizable share of public opinion, which holds that saving a life should take priority over any number of cures for minor ailments. I propose two possible explanations for this opinion, one debunking and one vindicatory. I also outline how well-designed surveys and moral inquiry could help decide (...) between them. Finally, I consider how priority-setting principles could be adjusted if the view that saving a life always trumps alleviating small burdens were vindicated. (shrink)

This paper deals with the conditions of liability to self-defense. When I use the term liability, I mean moral liability. This is different from desert. If I am liable to be killed in self-defense, it does not follow that I deserve to be killed. In short, desert entails liability but liability does not entail desert. My use of the term in this paper may be stated succinctly as follows: if killing a person will neither wrong him nor violate his rights, (...) he is morally liable to be killed. A person poses an unjust threat when he threatens harms that are neither justified nor excused. A person is culpable for an unjust threat if he intends the threat he poses, is a morally responsible agent, and there are no mitigating circumstances, such as duress, that excuse his actions. A person is at fault, but not culpable, for an unjust threat if he is a morally responsible agent, has acted unreflectively, recklessly, though not maliciously, in a way that poses risks to others. Though culpability entails fault, fault does not entail culpability; as I will explain later, a person does not have to be culpable in order to be at fault for an unjust threat. (shrink)
