This paper argues that certain central tenets of the traditional theory of the just war cannot be correct. It then advances an alternative account grounded in the same considerations of justice that govern self-defense at the individual level. The implications of this account are unorthodox. It implies that, with few exceptions, combatants who fight for an unjust cause act impermissibly when they attack enemy combatants, and that combatants who fight in a just war may, in certain circumstances, legitimately target noncombatants (...) who bear a significant degree of moral responsibility for a wrong, when the prevention or rectification of that wrong constitutes a just cause for war.

Arguments from human dignity feature prominently in the Lethal Autonomous Weapons moral feasibility debate, even though their exists considerable controversy over their role and soundness and the notion of dignity remains under-defined. Drawing on the work of Dieter Birnbacher, I fix the sub-discourse as referring to the essential value of human persons in general, and to postulated moral rights of combatants not covered within the existing paradigm of the International Humanitarian Law in particular. I then review and critique dignity-based arguments (...) against LAWS: argument from faulty targeting process, argument from objectification, argument from underappreciation of the value of human life and the argument from the absence of mercy. I conclude that the argument from the absence of mercy is the only dignity-based argument that is both valid and irreducible to another class of arguments within the debate, and that it offers insufficient justification for a global ban on LAWS.

The ethical Principle of Proportionality requires combatants not to cause collateral harm excessive in comparison to the anticipated military advantage of an attack. This principle is considered a major (and perhaps insurmountable) obstacle to ethical use of autonomous weapon systems (AWS). This article reviews three possible solutions to the problem of achieving Proportionality compliance in AWS. In doing so, I describe and discuss the three components Proportionality judgments, namely collateral damage estimation, assessment of anticipated military advantage, and judgment of “excessiveness”. (...) Some possible approaches to Proportionality compliance are then presented, such as restricting AWS operations to environments lacking civilian presence, using AWS in targeted strikes in which proportionality judgments are pre-made by human commanders, and a ‘price tag’ approach of pre-assigning acceptable collateral damage values to military hardware in conventional attritional warfare. The article argues that application of these three compliance methods would result in AWS’ achieving acceptable Proportionality compliance levels in many combat environments and scenarios, allowing AWS to perform most key tasks in conventional warfare.

This paper offers a non-reductivist account of the requirement of legitimate authority in warfare. I first advance a distinction between private and public wars. A war is private where individuals defend their private rights with their private means. A war is public where it either aims to defend public rights or relies on public means. I argue that RLA applies to public war but not private war. A public war waged by a belligerent without legitimate authority involves a form of (...) illegitimate domination of the people. Contra the conventional wisdom that RLA is only an ad bellum principle, I show that RLA is also a vital in bello principle. Relying on the Kantian non-voluntarist account of political authority, I argue that only legitimate states have the right to wage public wars. However, I also contend that RLA is not an absolute requirement, even regarding the justice of public war. Under extremely unfavorable conditions, this requirement may be overridden by weighty considerations in favor of resorting to public war without legitimate authority. In sum, my account of RLA protects ordinary people from illegitimate coercion involved in guerrilla warfare in general yet generates proper permission for responsible, aspiring state founders to secure social justice by coercive means under extraordinary situations.

This article examines, through a theoretical lens, two issues concerning equality under international law thrown up by the ongoing Russo-Ukrainian War: the equal treatment of belligerents on different sides under international humanitarian law (IHL), which is being contested by revisionist just war theorists, and the unequal treatment of Ukrainians with different genders assigned at birth who are trying to flee Ukraine, which is being contested under international human rights law (IHRL). By examining different conceptions of equality through the lens of (...) social ontology, this article distinguishes between the regulatory focus of IHL on individual agency and the regulatory focus of IHRL on social structures, which directly influence how ‘difference’ and ‘sameness’ are recognized and determined for the purpose of conceptualizing equality. Because of IHL’s focus on individuals, whose agency is limited in war, only highly agential conduct (e.g. targeting civilians) makes a ‘difference’ under IHL. Meanwhile, outside IHL’s regulatory focus, the different causes of states’ participation in war are evened out as the ‘same’ structured positions occupied by different individuals, warranting their same treatment according to belligerent equality. On the other hand, because of IHRL’s focus on social structures, which heavily condition the individuals, structural arrangements make a ‘difference’ under IHRL. Outside IHRL’s regulatory focus, individuals’ different innate characteristics such as sexual characteristics are evened out as the ‘same’ agential quality of being human, warranting their same treatment according to sex equality. The article argues that the contestations about these equality principles find deeper roots in their divergent social ontological visions, the revelation of which can open up new spaces for dialogue on and inquiry into a common social world that grounds the legal conceptions of equality.

The principle of proportionality demands that a war (or action in war) achieve more goods than bads. In the philosophical literature there has been a wealth of work examining precisely which goods and bads may count toward this evaluation. However, in all of these discussions there is no mention of one of the most certain bads of war, namely the psychological harm(s) likely to be suffered by the combatants who ultimately must fight and kill for the purposes of winning in (...) conflict. This paper argues that harms to one’s own soldiers must be included in proportionality judgments, and goes on to argue that one of the most significant harms one’s soldiers face are the psychological stresses and traumas associated with combat. The arguments draw on a growing wealth of psychological literature exploring the connections between combatancy and psychological trauma, and highlight, in particular, the uniquely negative impact which killing has on a combatant’s mental well-being. The paper concludes that these factors place an almost certain and rather weighty negative weight in any proportionality calculations concerning wars with ground combatants who must fight “up close and personal”, and that for more remote warfighters, there is also evidence to show that they may suffer deep psychological harm as a result of their combat roles as well. The argument, however, does not attempt to demonstrate that these factors render war impermissible. Rather, it merely shows that these harms, or bads, which can be quite significant, must be factored into our considerations of proportionality. The arguments themselves are rather uncontroversial, but they bring to light an element in the moral calculus which is sadly overlooked in most discussions of the ethics of war. (shrink)

New scientific advances have created previously unheard of possibilities for enhancing combatants' performance. Future war fighters may be smarter, stronger, and braver than ever before. If these technologies are safe, is there any reason to reject their use? In this article, I argue that the use of enhancements is constrained by the importance of maintaining the moral responsibility of military personnel. This is crucial for two reasons: the military's ethical commitments require military personnel to be morally responsible agents, and moral (...) responsibility is necessary for integrity and the moral emotions of guilt and remorse, both of which are important for moral growth and psychological well-being. Enhancements that undermined combatants' moral responsibility would therefore undermine the military's moral standing and would harm combatants' well-being. A genuine commitment to maintaining the military's ethical standards and the well-being of combatants therefore requires a careful analysis of performance-enhancing technologies before they are implemented.

John Locke says that a victim is permitted to kill a Conditional Threat in self-defense. Yet, David Rodin argues that killing is disproportionate to the harm averted and is therefore impermissible. But Rodin mischaracterizes the situation faced by a Conditional Threat victim as analyzed by Locke. In this article, I aim to provide a more satisfactory reading of Locke on self-defense against Conditional Threats, particularly of the thesis that killing involves a proportionate response to the harm averted. In addition to (...) this, I also aim to further elaborate and defend Locke's view. First, I show that a Conditional Threat deprives his victim of her freedom to act as she thinks fit, without having to depend on the Conditional Threat's arbitrary will. Second, I argue that an interest in not being deprived of one's freedom to act as one thinks fit, without having to depend on another person's arbitrary will, by a conditional threat of deadly harm, is of sufficient value to make killing a proportionate act, especially if the person is highly morally culpable. If killing also meets the necessity condition of justified self-defense (admittedly, a big “if”), it follows that Locke, not Rodin, holds the correct view. (shrink)

A survey of just war theory literature reveals the existence of quite different lists of principles. This apparent arbitrariness raises a number of questions: What is the relation between ad bellum and in bello principles? Why are there so many of the former and so few of the latter? What order is there among the various principles? To answer these questions, I first draw on some recent work by Jeff McMahan to show that ad bellum and in bello principles are (...) not, as often portrayed, independent—the justice of conduct in war largely presupposes the justice of the recourse to war. Undermining this independence claim is one important step toward revealing the unified logical structure of just war theory. I then argue that we can see the dependence of the jus in bello upon the jus ad bellum , not just in the content of certain principles, but also in the structure of the two sets of principles: I construct a one-to-one mapping between ad bellum and in bello principles. In doing so, I argue also that the shared structure successfully finds place for the questions central to the evaluation of the morality of war: what is a sufficient provocation to use force, what objectives may be sought by force, why or for what ends, who has authority to decide to use force, and when or in what circumstances? Despite variations in expression, the theory allows for a coherent and comprehensive evaluation of morality in warfare. (shrink)

Currently, the central questions in the philosophical debate surrounding the ethics of automated warfare are (1) Is the development and use of autonomous lethal robotic systems for military purposes consistent with (existing) international laws of war and received just war theory?; and (2) does the creation and use of such machines improve the moral caliber of modern warfare? However, both of these approaches have significant problems, and thus we need to start exploring alternative approaches. In this paper, I ask whether (...) autonomous robots ought to be programmed to be pacifists. The answer arrived at is “Yes”, if we decide to create autonomous robots, they ought to be pacifists. This is to say that robots ought not to be programmed to willingly and intentionally kill human beings, or, by extension, participate in or promote warfare, as something that predictably involves the killing of humans. Insofar as we are the ones that will be determining the content of the robot’s value system, then we ought to program robots to be pacifists, rather than ‘warists’. This is (in part) because we ought to be pacifists, and creating and programming machines to be “autonomous lethal robotic systems” directly violates this normative demand on us. There are no mitigating reasons to program lethal autonomous machines to contribute to or participate in warfare. Even if the use of autonomous lethal robotic systems could be consistent with received just war theory and the international laws of war, and even if their involvement could make warfare less inhumane in certain ways, these reasons do not compensate for the ubiquitous harms characteristic of modern warfare. In this paper, I provide four main reasons why autonomous robots ought to be pacifists, most of which do not depend on the truth of pacifism. The strong claim being argued for here is that automated warfare ought not to be pursued. The weaker claim being argued for here is that automated warfare ought not to be pursued, unless it is the most pacifist option available at the time, and other alternatives have been reasonably explored, and we are simultaneously promoting a (long term) pacifist agenda in (many) other ways. Thus, the more ambitious goal of this paper is to convince readers that automated warfare is something that we ought not to promote or pursue, while the more modest—and I suspect, more palatable—goal is to spark sustained critical discussion about the assumptions underlying the drive towards automated warfare, and to generate legitimate consideration of its pacifist alternatives,in theory, policy, and practice.

The emerging discipline of Machine Ethics is concerned with creating autonomous artificial moral agents that perform ethically significant actions out in the world. Recently, Wallach and Allen (Moral machines: teaching robots right from wrong, Oxford University Press, Oxford, 2009) and others have argued that a virtue-based moral framework is a promising tool for meeting this end. However, even if we could program autonomous machines to follow a virtue-based moral framework, there are certain pressing ethical issues that need to be taken (...) into account, prior to the implementation and development stages. Here I examine whether the creation of virtuous autonomous machines is morally permitted by the central tenets of virtue ethics. It is argued that the creation of such machines violates certain tenets of virtue ethics, and hence that the creation and use of those machines is impermissible. One upshot of this is that, although virtue ethics may have a role to play in certain near-term Machine Ethics projects (e.g. designing systems that are sensitive to ethical considerations), machine ethicists need to look elsewhere for a moral framework to implement into their autonomous artificial moral agents, Wallach and Allen’s claims notwithstanding.

This article analyses proportionality as a potential element of a theory of morally justified surveillance, and sets out a teleological account. It draws on conceptions in criminal justice ethics and just war theory, defines teleological proportionality in the context of surveillance, and sketches some of the central values likely to go into the consideration. It then explores some of the ways in which deontologists might want to modify the account and illustrates the difficulties of doing so. Having set out the (...) account, however, it considers whether the proportionality condition is necessary to a theory of morally justified surveillance. The article concludes that we need and should apply only a necessity condition, but notes that proportionality considerations may retain some use in in practice, as a form of coarse‐grained filter applied before assessing necessity when deliberating the permissibility of potential forms of surveillance.

This essay argues that culpability and responsibility are independent notions, even though some of the same facts make us both responsible and culpable. Responsibility for one’s conduct is grounded in the strength of the agential connection between oneself and one’s conduct. Culpability for one’s conduct is the vices that give rise to that conduct. It then argues that responsibility and culpability for causing a threat are each grounds of liability to defensive harm independent of the other.

This article argues that the reduction of the morality of killing in war to the morality of killing in self-defense by ‘reductive-individualist’ revisionist just war theories is inconsistent, because when those theories apply the moral notion of self-defense to the morality of killing in war, they do not preserve the two conceptions of the “individual” inherent in this notion. The article demonstrates this inconsistency in two steps: First, it disentangles the two conceptions of the individual inherent to the notion of (...) self-defense, namely (1) that the individual is an “entity” potentially bearing a right to self-defense (unlike, e.g., groups) and (2) that the individual is a “particular,” where “particular” signifies that every human is different from every other human. The conception of the individual as a “particular” is tied to the idea that a justification grounded in a rule of self-defense is necessarily “concrete,” in the sense of referring to individually given and specific perceptions or cases, as opposed to “abstract,” in the sense of being detached from specific perceptions or cases. The article then demonstrates that reductive individualism reflects the first notion of the individual, but not the second. Due to the “loss” of the individual as a “particular”, the reductive-individualist reduction of the morality of killing in war to the morality of killing in self-defense is inconsistent, and hence its justification of killing in war grounded in self-defense is not concrete. Since such a justification must be concrete, reductive individualism cannot offer a justification for belligerent killing. (shrink)

This article presents an analytic critique of the predominant revisionist theoretical paradigm of just war (henceforth: revisionism). This is accomplished by means of a precise description and explanation of the practicability problem that confronts it, namely that soldiers that revisionism would deem “unjust” are bound to fail to fulfil the duties that revisionism imposes on them, because these duties are overdemanding. The article locates the origin of the practicability problem in revisionism’s overidealized conception of a soldier as an individual rational (...) agent analogous to the aggressor or defender in a case of lethal self-defense, who is capable of reflecting on the morality of his status in war and of the killing he performs and thus of recognizing his revisionist duties. Revisionism, however, ignores the following fact: Killing in war is not a natural human behavior. This is why training soldiers to kill is—and arguably always has been—a necessity for the existence of war and the killing that occurs in it. Moreover, this training involves a certain level of moral desensitization to violence whose goal is to prevent soldiers from thoroughly reflecting on the morality of the killing they engage in. Hence, war and killing can only exist if soldiers are trained in such a way that they do not reflect on whether they could be addressees of revisionist duties in the first place. This means that military training is a “constitutive condition” of soldiers and war, which is why it cannot excuse their noncompliance with revisionist duties, thus making these duties categorically overdemanding. The argument here draws on the paradigmatic example of modern US military killing conditioning (MC), but embeds it into a broader military-historical perspective that describes how soldiers have always needed to be mentally and morally influenced in order to enable war and killing. The article’s explanation of revisionism’s practicability problem has a constructive consequence for future theory-building in the ethics of war: It implies that a potentially revised ethical theory of war must necessarily analyze the institutions that allocate belligerent resources, if it aims to morally assess battlefield behavior in a practicable manner.

ABSTRACTThe aim of this paper is to draw attention to an issue which has been largely overlooked in contemporary just war theory – namely the impact that the conditions under which an army is assembled are liable to have on the judgments that are made with respect to traditional principles of jus ad bellum and jus in bello. I argue that the way in which an army is assembled can significantly alter judgments regarding the justice of a war. In doing (...) so, I present and defend a principle of ‘just assembly’ and argue that satisfying this principle is an essential part of any deliberation regarding the justice of a particular conflict.

There are different formulations of the doctrine of double effect, and sometimes philosophers propose “revisions” or alternatives, like the means principle, for instance. To demonstrate that such principles are needed in the first place, one would have to compare cases in which all else is equal and show that the difference in intuitions, if any, can only be explained by the one remaining difference and thus by the principle in question. This is not the methodology defenders of the DDE and (...) of related principles use, however. I will discuss how they actually proceed, focusing on their preferred four pairs of examples. While these examples might have rhetorical force, they are nevertheless philosophically and methodologically useless. As a corrective, I shall offer examples that do keep all else equal. These examples undermine the DDE and related principles. I then argue that while the Loop case and the “closeness” problem in the context of Jonathan Bennett’s Sophisticated Bomber example might once have been an embarrassment of sorts for defenders of the DDE, meanwhile their discussion serves as a convenient distraction from the many clear examples disproving the DDE and related principles. I conclude that the methodological mistakes found in defenses of the DDE – the biased framing, the rigged examples, the empirically unwarranted claims about how widely shared certain intuitions are, and the avoidance of the strongest counter-examples – can only be explained by systematic bias. There is simply no sufficient intuitive support for the DDE or related principles. Thus, instead of looking for their “rationales,” they should be abandoned. (shrink)

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

According to the dominant position in the just war tradition from Augustine to Anscombe and beyond, there is no "moral equality of combatants." That is, on the traditional view the combatants participating in a justified war may kill their enemy combatants participating in an unjustified war - but not vice versa (barring certain qualifications). I shall argue here, however, that in the large number of wars (and in practically all modern wars) where the combatants on the justified side violate the (...) rights of innocent people ("collateral damage"), these combatants are in fact liable to attack by the combatants on the unjustified side. I will support this view with a rights-based account of liability to attack and then defend it against a number of objections raised in particular by Jeff McMahan. The result is that the thesis of the moral equality of combatants holds good for a large range of armed conflicts while the opposing thesis is of very limited practical relevance. (shrink)

Even among those who find lethal defense against non-responsible threats, innocent aggressors, or justified aggressors justified even in one to one cases, there is a debate as to what the best explanation of this permissibility is. The contenders in this debate are the liability account, which holds that the non-responsible or justified human targets of the defensive measures are liable to attack, and the justified infringement account, which claims that the targets retain their right not to be attacked but may (...) be attacked anyway, even in one to one situations. Given that we normally think that rights are trumps, this latter claim is counter-intuitive and rather surprising, and therefore in need of justification and explanation. So far only Jonathan Quong has actually tried to provide an explanation; however, I will argue that his explanation fails and that Quong’s own account of liability is misguided. I then address Helen Frowe’s critique of the liability account. She makes the important concession that the tactical bomber has to compensate his victims, but she tries to block the conclusion that he must therefore be liable. I will demonstrate that her attempt to explain away liability fails once that concession is made. (shrink)

Jeff McMahan has recently proposed what he calls a “combined liability-lesser-evil justification.” Its core idea is that the fact that someone has no right against the infliction of a certain lesser harm makes it easier for the necessity or lesser evil justification to justify inflicting a greater harm on him. This idea has been taken up by authors like Saba Bazargan or Helen Frowe. I will argue that McMahan’s basic idea is implausible to begin with, leads to counter-intuitive results, and (...) seems to stem from a confusion between discounting the rights of wrongdoers and “subtracting” one right from the other. I then argue that Bazargan’s conclusion that minimally responsible threats can sometimes be killed as well as certain other conclusions that Bazargan regards as a particular advantage of his “hybrid account” are single-handedly generated by one element of that account, namely by the lesser-evil discounting view. Thus, the hybrid view is redundant. Moreover, both the hybrid view and the lesser evil discounting view of killing MRTs have strongly counter-intuitive implications. Finally, I show that Frowe’s application of the combined justification to non-responsible threats is entirely arbitrary and therefore useless. “Combined liability-lesser-evil justifications” should be rejected.

In this article, I argue for a distinct and novel right-based account of risks and I call it the Sophisticated High-risk Thesis. I argue that there is a distinction between rights-infringing risk impositions and no-rights-infringing risk impositions. An action imposing a high risk of harm infringes rights, whereas an act imposing a low risk of harm does not. I also suggest three principles that govern the permissibility of highly risky actions. If a highly risky action meets the conditions specified by (...) any of these three principles, it can be justified. These principles are the consent principle*, the prevent disaster principle* and the reciprocity principle**. I show that the Sophisticated High-risk Thesis is, in general, better than the alternative Risk Thesis defended by McCarthy. (shrink)

Alon Harel defines extreme cases as those in which the only way to avert a destructive threat is to harm innocent people. He rejects traditional consequentialist and non-consequentialist approaches because of the type of reasoning they both employ. I interpret Harel as making two central objections to this form of reasoning. First, traditional approaches require comparisons to be made about the value of human life. Second, decisions in extreme cases, even if permissible, should not be made under the guidance of (...) rules. I argue that these objections, though prima facie plausible, are on reflection relatively weak, and I offer instead a more moderate argument that vindicates Harel’s general thesis that deliberation is morally relevant. More specifically, I argue that whether one acts on certain conditions affects both the moral permissibility of one’s actions and the duties owed by others. (shrink)

This essay analyzes the use of military robots in terms of the jus in bello concepts of discrimination and proportionality. It argues that while robots may make mistakes, they do not suffer from most of the impairments that interfere with human judgment on the battlefield. Although robots are imperfect weapons, they can exercise as much restraint as human soldiers, if not more. Robots can be used in a way that is consistent with just war theory when they are programmed to (...) avoid using force against all but the most clearly hostile targets. However, the essay also cautions against using robots for counterinsurgency because they may alienate people in the contested area and lead to an escalation of hostilities. (shrink)

The focus of this paper is an influential family of views in the ethics of self-defense and war: views that ground the agent’s liability to be attacked in self-defense in the agent’s moral responsibility for the threat posed. I critically examine the concept of responsibility employed by such views, by looking at potential connections with the contemporary literature on moral responsibility. I start by uncovering some of the key assumptions that Responsibility Views make about the relevant concept of responsibility, and (...) by scrutinizing those assumptions under the lens of more general theorizing about responsibility. I identify an important conflict that arises at that point. The problem is that the concept presupposed by Responsibility Views is in tension with the standard way of understanding the connection between the neutral and non-neutral forms of moral responsibility. I draw attention to a particular strategy that could be used to address this challenge, but I also identify some important obstacles that stand in the way. (shrink)

Jonathan Quong Ethics, 119, 507–537 has recently argued that the permissibility of killing innocent threats turns on a distinction between eliminative and opportunistic agency. When we kill bystanders we view them under the guise of opportunism by using them as mere survival tools, but when we kill threats we simply eliminate them. According to Quong, the distinction between opportunistic and eliminative agency reveals that there are two different ways of killing someone as a means to save your own life. Call (...) this the Means Distinction. In this note, I argue that although the Means Distinction seems prima facie plausible it is not a sufficient explanation for the permissibility of killing threats. My argument against the Means Distinction is two-fold. Most non-consequentialists accept that the Means Distinction carries some moral significance, but I argue that this is a mistake: we do not have any reason to believe that opportunistic killings are, in general, worse than eliminative killings. Following this, I argue that even if we accept the Means Distinction, there are threat-type scenarios in which there is no intuitive difference between killing a threat opportunistically and killing a threat eliminatively.

In this article, I develop a general explanatory model of the liability and lesser evil justifications of harm. Despite their respective provenance in consequentialist and deontological ethics, both justifications are, at root, rich forms of the proportionality relationship between a shared set of underlying normative variables. The nature of the proportionality relationship, and the conditions under which it operates, differ between the two forms of justification. The article explores these differences in detail and the implications they have for the justification (...) of self-defense and war. (shrink)

Philosophers working on the morality of harm have paid surprisingly little attention to the problem of manipulation. The aim of this paper is to remedy this lacuna by exploring how liability to defensive harm is affected by the fact that someone posing an unjust threat has been manipulated into doing so. In addressing this problem, the challenge is to answer the following question: Why should it be the case that being misled into posing an unjust threat by manipulation makes a (...) difference to one’s liability, as compared to being misled into doing so by natural events or by someone’s honest attempt to persuade us? To answer this question, I first outline an account of manipulation and then use it to defend what I shall call the “Pre-emption Principle.”. (shrink)

Agent-based virtue ethical theories must deal with the problem of right action: if an action is right just in case it expresses a virtuous motive, then how can an agent perform the right action but for the wrong reason, or from a vicious motive? Some recent agent-based accounts purport to answer this challenge and two other related problems. Here I assess these accounts and show them to be inadequate answers to the problem of right action. Overall, it is shown that (...) the most recent and promising attempts at squaring agent-based virtue ethics with commonsense morality are flawed, and so, the case for agent-basing in general that much dimmer.

Despite a common agenda of normative analysis of the international order, philosophical work on international political morality and international law and legal scholarship have, until recently, worked at a distance from one another.The mutual suspicion can be traced to different aims and methodologies, including a divide between work on matters of deep structure, on the one hand, and practical institutional analysis and prescription, on the other. Yet international law is a key part of the normative practices ofstates, has a direct (...) effect on state behavior, and, as a meth-odological matter, can contribute to good theorizing onmatters of international ethics. Recently, philosophical workhas demonstrated a greater engagement with the moral aspects of international law. One strand of scholarship has treated the rules of international law as a proper subject for philosophical inquiry. Another has used international legal rules to support moral arguments about aspects of the international order. Future dialogue and cooperation would benefit both fields, in particular on the challenges to global cooperation from nationalism and on strategies for allocating responsibilities among global actors for rectifying global harms.

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

This paper discusses Jessica Flanigan’s book, _Pharmaceutical Freedom_. The paper advances two main claims. First, the paper argues that, despite what Flanigan claims, there is a coherent way to endorse the Doctrine of Informed Consent while resisting the view that there is a right to self-medicate. Second, the paper argues that Flanigan is committed to a more radical conclusion than she acknowledges in the book; namely, that under some conditions it is morally permissible for people to take medications from drug (...) manufacturers or pharmacies without paying the full price for those medications. The paper concludes by suggesting that this thesis about permissible theft, when combined with some further premises regarding the morality of defensive force, implies some even more radical conclusions regarding the use of force to obtain these medications.

We propose that the prevalent moral aversion to AWS is supported by a pair of compelling objections. First, we argue that even a sophisticated robot is not the kind of thing that is capable of replicating human moral judgment. This conclusion follows if human moral judgment is not codifiable, i.e., it cannot be captured by a list of rules. Moral judgment requires either the ability to engage in wide reflective equilibrium, the ability to perceive certain facts as moral considerations, moral (...) imagination, or the ability to have moral experiences with a particular phenomenological character. Robots cannot in principle possess these abilities, so robots cannot in principle replicate human moral judgment. If robots cannot in principle replicate human moral judgment then it is morally problematic to deploy AWS with that aim in mind. Second, we then argue that even if it is possible for a sufficiently sophisticated robot to make ‘moral decisions’ that are extensionally indistinguishable from (or better than) human moral decisions, these ‘decisions’ could not be made for the right reasons. This means that the ‘moral decisions’ made by AWS are bound to be morally deficient in at least one respect even if they are extensionally indistinguishable from human ones. Our objections to AWS support the prevalent aversion to the employment of AWS in war. They also enjoy several significant advantages over the most common objections to AWS in the literature.

Can the global poor wage a just redistributive war against the global rich? The moral norms governing the use of force are usually considered to be very strict. Nonetheless, some philosophers have recently argued that violating duties of global justicecanbe a just cause for war. This paper discusses redistributive wars. It shows that the strength of these arguments is contingent on the underlying account of global distributive justice. The paper focuses on the “doing harm argument,” under the assumption that the (...) alternative “allowing harm argument” is a more difficult route to justify redistributive wars. After highlighting several preliminary problems, the paper breaks down and assesses in depth the “doing harm argument”: the empirical premise, the rights violation that constitutes the wrong, liability and degrees of responsibility, and the conditions for justified self-defense. By drawing on principles reflected in criminal law, this paper argues that a general “doing harm argument” for redistributive wars is unconvincing, while a reinterpretation of that argument could theoretically give rise to a just cause for war.

The war in just war theory Just war theory has an ancient pedigree. While the substantive norms and application of those norms have always been debated, the debate today is entirely polarized. So polarized, that there seems to be a ‘war’ raging in just war theory. On one side are representatives of Walzer’s conventional position and on the other side so-called revisionists as McMahan, Fabre, Rodin, and Frowe. This paper offers a critical analysis of that dichotomy. While most of the (...) debate is focused on the substantive level (the norms itself), I focus here on the conceptual level (terminology and character of the positions) and meta-level (the underlying theoretical premises). My aim is threefold: to assist readers in understanding contemporary contributions to just war theory; to facilitate a truce between both camps by highlighting respective strengths and weaknesses and by exposing a certain division of labor; and to suggest improvements for both positions.

Recent work in the ethics of war has done much to challenge the collectivism of the convention-based, Walzerian just war theory. In doing so, it raises the question of when it is permissible for soldiers to resort to force. This article considers this issue and, in doing so, argues that the rejection of collectivism in just war should go further still. More specifically, it defends the ‘Individual-Centric Approach’ to the deep morality of war, which asserts that the justifiability of an (...) individual’s contribution to the war, rather than the justifiability of the war more generally, determines the moral acceptability of their participation. It then goes on to present five implications of the Individual-Centric Approach, including for individual liability to attack in war. (shrink)

In this contribution, I defend the standard list of jus ad bellum principles. In The Ethics of War and the Force of Law: A Modern Just War Theory, Uwe Steinhoff endorses only three principles of jus ad bellum (right intention, just cause, and proportionality) and claims that the others are redundant. I argue that, although fundamentally all jus ad bellum principles can be reduced to proportionality, in practice it is vital to retain the main jus ad bellum criteria as separate (...) principles.

Gregory Reichberg’s argument against my reading of the classical just war theorists falsely assumes that if just cause is unilateral, then there is no moral equality of combatants. This assumption is plausible if we assume an individualist framework. However, the classical theorists accepted quasi-Aristotelian, communitarian social ontologies and theories of justice. For them, the political community is ontologically and morally prior to the private individual. The classical just war theorists build their theories within this framework. They argue that just war (...) is only waged by supra-individual political communities for irreducibly social ends. War by private individuals for private ends is always unjust. The ends sought in just war presuppose the justice of a hierarchy of authority over war such that the soldier is obligated to serve in war upon the command of his legitimate authority. In this way, the classical theorists accept a unilateral theory of just cause and a division of authority over war that entails the possibility of the moral equality of combatants. (shrink)

Conventional modern just war theory is fundamentally incoherent. On the one hand, the theory contains a theory of public war wherein ethical responsibility for the justice of war belongs uniquely to political sovereigns while subjects, including soldiers, are obligated to serve in war upon the sovereign’s command. On the other hand, the theory contains a theory of discrimination which presupposes that participants in war, including soldiers, are responsible for the justice of the wars they fight. Moreover, these two components are (...) derived from two inconsistent visions of political justice. The theory of public war, it turns out, is derived from a theory of justice that places the value of political society conceived of as a supra-individual communal entity above the value of the private individual. The theory of discrimination, however, is derived from a theory of justice that places the value of the private individual above that of political society. This inconsistency is revealed by analyzing the theories of Vitoria, Grotius, and Walzer. Appreciating this problem also helps situate the recent revisionist critiques of conventional just war theory. (shrink)

Those of us who are not pacifists face an obvious challenge. Common-sense morality contains a stringent constraint on intentional killing, yet war involves homicide on a grand scale. If wars are to be morally justified, it needs be shown how this conflict can be reconciled. A major fault line running throughout the contemporary just war literature divides two approaches to attempting this reconciliation. On a ‘reductivist’ view, defended most prominently by Jeff McMahan, the conflict is largely illusory, since such killing (...) can be justified by aggregating individuals’ ordinary permissions to use force in self- and other-defence. In opposition, a rival ‘nonreductivist’ approach holds that these considerations are insufficient for the task. One prominent version of non-reductivism grounds the permission to kill in combatants’ membership in certain kinds of group or association. The key claim is that participation in certain morally important relationships can provide an independent source of permission for killing in war. This paper argues that non-reductivism should be rejected. It does so by pushing a dilemma onto non-reductivists: if they are successful in showing that the relevant relationships can generate permissions to kill in war, they must also jettison the most intuitive restrictions on conduct in war—the constraint on intentionally killing morally innocent non-combatants most saliently. Since this conclusion is unacceptable, non-reductivism should be rejected. (shrink)

Since its earliest incarnations, just war theory has included the requirement that war must be initiated and waged by a legitimate authority. However, while recent years have witnessed a remarkable resurgence in interest in just war theory, the authority criterion is largely absent from contemporary discussions. In this paper I aim to show that this is an oversight worth rectifying, by arguing that the authority criterion plays a much more important role within just war theorising than is commonly supposed. As (...) standardly understood, the authority criterion provides a necessary condition for the justification of the resort to war, but has no bearing on the question of permissible conduct in war. In opposition, I argue for an alternative interpretation of the criterion, which attributes to it a fundamental role in assessing this latter question. With this revised interpretation in place, I then demonstrate its advantages by applying it to the practical issue of armed conflicts that are initiated and fought by non-traditional belligerents. While several theorists have recognised that this common feature of modern armed conflict poses a challenge to mainstream just war theory in general—and to the authority criterion in particular—I argue that existing discussions frequently misconstrue the nature of the challenge, since they assume the standard interpretation of the authority requirement and its role within the theory. I then show that the revised interpretation provides a clearer account of both the challenge posed by non-traditional belligerency and the kind of response that it requires. (shrink)
