It has been argued that implicit biases are operative in philosophy and lead to significant epistemic costs in the field. Philosophers working on this issue have focussed mainly on implicit gender and race biases. They have overlooked ideological bias, which targets political orientations. Psychologists have found ideological bias in their field and have argued that it has negative epistemic effects on scientific research. I relate this debate to the field of philosophy and argue that if, as some studies suggest, the (...) same bias also exists in philosophy then it will lead to hitherto unrecognised epistemic hazards in the field. Furthermore, the bias is epistemically different from the more familiar biases in respects that are important for epistemology, ethics, and metaphilosophy. (shrink)

Members of the field of philosophy have, just as other people, political convictions or, as psychologists call them, ideologies. How are different ideologies distributed and perceived in the field? Using the familiar distinction between the political left and right, we surveyed an international sample of 794 subjects in philosophy. We found that survey participants clearly leaned left (75%), while right-leaning individuals (14%) and moderates (11%) were underrepresented. Moreover, and strikingly, across the political spectrum, from very left-leaning individuals and moderates to (...) very right-leaning individuals, participants reported experiencing ideological hostility in the field, occasionally even from those from their own side of the political spectrum. Finally, while about half of the subjects believed that discrimination against left- or right-leaning individuals in the field is not justified, a significant minority displayed an explicit willingness to discriminate against colleagues with the opposite ideology. Our findings are both surprising and important, because a commitment to tolerance and equality is widespread in philosophy, and there is reason to think that ideological similarity, hostility, and discrimination undermine reliable belief formation in many areas of the discipline.

When scientists or science reporters communicate research results to the public, this often involves ethical and epistemic risks. One such a risk arises when scientific claims cause cognitive or behavioral changes in the audience that contribute to the self-fulfillment of these claims. Focusing on such effects, I argue that the ethical and epistemic problem that they pose is likely to be much broader than hitherto appreciated. Moreover, it is often due to a psychological phenomenon that has been neglected in the (...) research on science communication, namely that many people tend to conform to descriptive norms, that is, norms capturing (perceptions of) what others commonly do, think, or feel. Because of this tendency, science communication can produce significant social harm. I contend that scientists have a responsibility to assess the risk of this potential harm and consider adopting strategies to mitigate it. I introduce one such a strategy and argue that its implementation is independently well motivated by the fact that it helps improve scientific accuracy. (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)

Confirmation bias is one of the most widely discussed epistemically problematic cognitions, challenging reliable belief formation and the correction of inaccurate views. Given its problematic nature, it remains unclear why the bias evolved and is still with us today. To offer an explanation, several philosophers and scientists have argued that the bias is in fact adaptive. I critically discuss three recent proposals of this kind before developing a novel alternative, what I call the ‘reality-matching account’. According to the account, confirmation (...) bias evolved because it helps us influence people and social structures so that they come to match our beliefs about them. This can result in significant developmental and epistemic benefits for us and other people, ensuring that over time we don’t become epistemically disconnected from social reality but can navigate it more easily. While that might not be the only evolved function of confirmation bias, it is an important one that has so far been neglected in the theorizing on the bias. (shrink)

It has recently been suggested that politically motivated cognition leads progressive individuals to form beliefs that underestimate real differences between social groups and to process information selectively to support these beliefs and an egalitarian outlook. I contend that this tendency, which I shall call ‘egalitarian confirmation bias’, is often ‘Mandevillian’ in nature. That is, while it is epistemically problematic in one’s own cognition, it often has effects that significantly improve other people’s truth tracking, especially that of stigmatized individuals in academia. (...) Due to its Mandevillian character, egalitarian confirmation bias isn’t only epistemically but also ethically beneficial, as it helps decrease social injustice. Moreover, since egalitarian confirmation bias has Mandevillian effects especially in academia, and since progressives are particularly likely to display the bias, there is an epistemic reason for maintaining the often-noted political majority of progressives in academia. That is, while many researchers hold that diversity in academia is epistemically beneficial because it helps reduce bias, I argue that precisely because political diversity would help reduce egalitarian confirmation bias, it would in fact in one important sense be epistemically costly. (shrink)

In the philosophy of science, it is a common proposal that values are illegitimate in science and should be counteracted whenever they drive inquiry to the confirmation of predetermined conclusions. Drawing on recent cognitive scientific research on human reasoning and confirmation bias, I argue that this view should be rejected. Advocates of it have overlooked that values that drive inquiry to the confirmation of predetermined conclusions can contribute to the reliability of scientific inquiry at the group level even when they (...) negatively affect an individual’s cognition. This casts doubt on the proposal that such values should always be illegitimate in science. It also suggests that advocates of that proposal assume a narrow, individualistic account of science that threatens to undermine their own project of ensuring reliable belief formation in science. (shrink)

Victor Tadros thinks the idea that in a conflict both sides may permissibly use force should (typically) be rejected. Thus, he thinks that two shipwrecked persons should not fight for the only available flotsam (which can only carry one person) but instead toss a coin, and that a bomber justifiably attacking an ammunitions factory must not be counterattacked by the innocent bystanders he endangers. I shall argue that Tadros’s claim rests on unwarranted assumptions and is also mistaken in the light (...) of the moral reasoning that he himself offers in support of his ‘means principle’. (shrink)

In the tradition of just war theory two assumptions have been taken pretty much for granted: first, that there are quite a lot of justified wars, and second, that there is a moral inequality of combatants, that is, that combatants participating in a justified war may kill their enemy combatants participating in an unjustified war but not vice versa. I will argue that the first assumption is wrong and that therefore the second assumption is virtually irrelevant for reality. I will (...) also argue, primarily against Jeff McMahan, that his particular thesis about the moral inequality of “just” and “unjust combatants” is an analytical truth which, however, does hardly apply to anything (there are few if any “unjust combatants” as he defines them). If one takes his thesis less literally, namely in the sense of a thesis about combatants participating in a justified war and combatants participating in an unjustified war, it is correct in principle, but still of little practical relevance even if one disregarded the fact that there are virtually no justified wars. One of the reasons for this is that, contrary to McMahan’s claims, justification does not defeat liability. (shrink)

I argue that the criterion of just cause is not independent of proportionality and other valid jus ad bellum criteria. One cannot know whether there is a just cause without knowing whether the other (valid) criteria (apart from ‘right intention’) are satisfied. The advantage of this account is that it is applicable to all wars, even to wars where nobody will be killed or where the enemy has not committed a rights violation but can be justifiably warred against anyway. This (...) account also avoids the inefficiency of having proportionality considerations come up at two different points: in a separate criterion of just cause and in the criterion of proportionality proper. ‘Right intention’, the subjective element of the justification of a war, on the other hand, is not to be subsumed under the criterion of just cause: there can be a just cause without anybody knowing it. Conversely, however, the subjective element requires that those responsible for waging the war do know that the justifying objective conditions are fulfilled. This is in one sense more demanding than traditional just war theory; in another sense, however, it is less demanding: nobody needs to intend to fight for a ‘just aim’. (shrink)

Thomas Pogge claims "that, by shaping and enforcing the social conditions that foreseeably and avoidably cause the monumental suffering of global poverty, we are harming the global poor ... or, to put it more descriptively, we are active participants in the largest, though not the gravest, crime against humanity ever committed." In other words, he claims that by upholding certain international arrangements we are violating our strong negative duties not to harm, and not just some positive duties to help. I (...) shall argue that even if Pogge were correct in claiming that certain rich states or at least the rich states collectively violate certain negative duties towards the poor and harm the poor, he is far too hasty in concluding that "we," the citizens of those states, are thus harming the global poor or violating our negative duties towards them. In fact, his conclusion can be shown to be wrong not least of all in the light of some of his own assumptions about collective responsibility, the enforceability of human rights, and terrorism. In addition, I will also argue that his view that we share responsibility for the acts of our political "representatives," who allegedly act "on our behalf," is unwarranted. (shrink)

This paper is not so much concerned with the question under which circumstances self-defense is justified, but rather with other normative features of self-defense as well as with the source of the self-defense justification. I will argue that the aggressor’s rights-forfeiture alone – and hence the liberty-right of the defender to defend himself – cannot explain the intuitively obvious fact that a prohibition on self-defense would wrong victims of attack. This can only be explained by conceiving of self-defense also as (...) a claim-right. However, I will also argue that a claim-right cannot ground the self-defense justification either. Rather, what grounds the self-defense justification and its particular strength and scope is the fact that self-defense is an act-specific agent-relative prerogative: a defender is allowed to give particularly grave weight to his interest in engaging in self-defense, which distinguishes self-defense from most other acts. This is not the same as saying that he has a right or a liberty to engage in self-defense. Thus, self-defense, understood as a normative concept, is a claim-right, a liberty-right, and an act-specific agent-relative prerogative. (shrink)

Why do we engage in folk psychology, that is, why do we think about and ascribe propositional attitudes such as beliefs, desires, intentions etc. to people? On the standard view, folk psychology is primarily for mindreading, for detecting mental states and explaining and/or predicting people’s behaviour in terms of them. In contrast, McGeer (1996, 2007, 2015), and Zawidzki (2008, 2013) maintain that folk psychology is not primarily for mindreading but for mindshaping, that is, for moulding people’s behavior and minds (e.g., (...) via the imposition of social norms) so that coordination becomes easier. Mindreading is derived from and only as effective as it is because of mindshaping, not vice versa. I critically assess McGeer’s, and Zawidzki’s proposal and contend that three common motivations for the mindshaping view do not provide sufficient support for their particular version of it. I argue furthermore that their proposal underestimates the role that epistemic processing plays for mindshaping. And I provide reasons for favouring an alternative according to which, in social cognition involving ascriptions of propositional attitudes, neither mindshaping nor mindreading is primary but both are complementary in that effective mindshaping depends as much on mindreading as effective mindreading depends on mindshaping. (shrink)

Practically all modern definitions of war rule out that individuals can wage war. They conceive of war as a certain kind of conflict between groups. In fact, many definitions even restrict the term “war” to sustained armed conflicts between states. Instead of taking such definitions as points of departure, the article starts from scratch. I first explain what an explication of the concept of “war” should achieve. I then introduce the fundamental, and frequently overlooked, distinction between war as an historical (...) event and war as an action. It is war as action—which, unlike events, can be right or wrong—that I explicate. Testing our linguistic intuitions with different examples of conflict I isolate several criteria that a war proper has to fulfill and try to demonstrate that not only collectives but individuals, too, can wage war. In conclusion I examine alternative definitions of war and show that in comparison to them mine fares rather well. (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)

In empirically informed research on action explanation, philosophers and developmental psychologists have recently proposed a teleological account of the way in which we make sense of people’s intentional behavior. It holds that we typically don’t explain an agent’s action by appealing to her mental states but by referring to the objective, publically accessible facts of the world that count in favor of performing the action so as to achieve a certain goal. Advocates of the teleological account claim that this strategy (...) is our main way of understanding people’s actions. I argue that common motivations mentioned to support the teleological account are insufficient to sustain its generalization from children to adults. Moreover, social psychological studies, combined with theoretical considerations, suggest that we do not explain actions mainly by invoking publically accessible, reason-giving facts alone but by ascribing mental states to the agent.

David Rodin denies that defensive wars against unjust aggression can be justified if the unjust aggression limits itself, for example, to the annexation of territory, the robbery of resources or the restriction of political freedom, but would endanger the lives, bodily integrity or freedom from slavery of the citizens only if the unjustly attacked state actually resisted the aggression. I will argue that Rodin's position is not correct. First, Rodin's comments on the necessity condition and its relation to an alleged (...) "duty to retreat" misinterpret the law, and a correct interpretation of the law is not only compatible with, but implies a permission to resist the "bloodless invader," and this is also the correct view from the perspective of morality. Second, Rodin's remarks on the proportionality of self-defense against conditional threats focus on physical or material harm but implausibly ignore the severity of the violations of autonomy and of the socio-legal or moral order that such conditional threats involve. Third, I will address Rodin's claim that defensive wars against "political aggression" are disproportionate because they risk the lives of those defended in an attempt to secure lesser interests. I will argue that this take on proportionality misses the point in an important respect, namely by confusing wide and narrow proportionality, and makes unwarranted assumptions about the alleged irrationality or impermissibility of incurring or imposing lethal risks to safeguard less vital interests. Next, I will also show that while Rodin talks of a "myth of national self-defense" and of the necessity of moving beyond traditional just war theory and international law, it is actually his interpretation of just war theory and international law that weaves myths. Finally, I will argue that Rodin's views on national self-defense on the one hand, and "war as law enforcement" on the other, are incoherent. (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)

In this paper, I will provide a conceptual analysis of the term self-defense and argue that in contrast to the widespread “instrumentalist” account of self-defense, self-defense need not be aimed at averting or mitigating an attack, let alone the harm threatened by it. Instead, on the definition offered here, an act token is self-defense if and only if a) it is directed against an ongoing or imminent attack, and b) the actor correctly believes that the act token is an effective (...) form of resistance or the act token belongs to an act type that usually functions as a means to resist an attack. While resistance is effective in making the attack more difficult, it can often be overcome and therefore does not necessarily stop or mitigate the attack. This concept of self-defense, I shall argue, not only matches ordinary language use and plausible accounts of self-defense in the legal literature but also has important practical implications in helping to avoid confusions about necessity and proportionality. In particular, it avoids the notorious problem of the “knowingly helpless rape victim” whose futile struggle against the rapist (futile in terms of averting or mitigating harm) counter-intuitively could not count as justified self-defense on an instrumentalist account.

Teleosemantics explains mental representation in terms of biological function and selection history. One of the main objections to the account is the so-called ‘Swampman argument’ (Davidson 1987), which holds that there could be a creature with mental representation even though it lacks a selection history. A number of teleosemanticists reject the argument by emphasising that it depends on assuming a creature that is fi ctitious and hence irrelevant for teleosemantics because the theory is only concerned with representations in real-world organisms (...) (Millikan 1996, Neander 1996, 2006, Papineau 2001, 2006). I contend that this strategy doesn’t succeed. I off er an argument that captures the spirit of the original Swampman objection but relies only on organisms found in the actual world. Th e argument undermines the just mentioned response to the Swampman objection, and furthermore leads to a particular challenge to strong representationalist theories of consciousness that endorse teleosemantics such as, e.g., Dretske’s (1995) and Tye’s (1995, 2000) accounts. On these theories, the causal effi cacy of consciousness in actual creatures will be undermined. (shrink)

This paper explores the nature of self-knowledge of beliefs by investigating the relationship between self-knowledge of beliefs and one's knowledge of other people's beliefs. It introduces and defends a new account of self-knowledge of beliefs according to which this type of knowledge is developmentally interconnected with and dependent on resources already used for acquiring knowledge of other people's beliefs, which is inferential in nature. But when these resources are applied to oneself, one attains and subsequently frequently uses a method for (...) acquiring knowledge of beliefs that is non-inferential in nature. The paper argues that this account is preferable to some of the most common empirically motivated theories of self-knowledge of beliefs and explains the origin of the widely discussed phenomenon that our own beliefs are often transparent to us in that we can determine whether we believe that p simply by settling whether p is the case. (shrink)

Recently, philosophers have appealed to empirical studies to argue that whenever we think that p, we automatically believe that p (Millikan 2004; Mandelbaum 2014; Levy and Mandelbaum 2014). Levy and Mandelbaum (2014) have gone further and claimed that the automaticity of believing has implications for the ethics of belief in that it creates epistemic obligations for those who know about their automatic belief acquisition. I use theoretical considerations and psychological findings to raise doubts about the empirical case for the view (...) that we automatically believe what we think. Furthermore, I contend that even if we set these doubts aside, Levy and Mandelbaum’s argument to the effect that the automaticity of believing creates epistemic obligations is not fully convincing.

This article considers the proportionality requirement of the self-defense justification. It first lays bare the assumptions and the logic—and often illogic—underlying very strict accounts of the proportionality requirement. It argues that accounts that try to rule out lethal self-defense against threats to property or against threats of minor assault by an appeal to the supreme value of life have counter-intuitive implications and are untenable. Furthermore, it provides arguments demonstrating that there is not necessarily a right not to be killed in (...) defense against theft or minor assaults. While there is a general moral right of self-defense and a general right to life, the scope of these rights depends on certain social facts that—even within a liberal framework—can differ from one society to another. Moreover, the proportionality of self-defense does not depend on the rights of the aggressor alone, but also on a precautionary rule, shaped by the balance of interests of the society in question and aimed at protecting innocent people and other social interests. This rule can protect an aggressor even in cases where he does not have the right to such protection. (shrink)

A standard example of a justified aggressor is the tactical bomber who is about to destroy an ammunitions factory in a proportionate, justified military attack, full well knowing that an innocent civilian bystander will also be killed by his attack (“collateral damage”). Intuitively it seems hard to believe that the innocent bystander threatened by the tactical bomber is morally prohibited from killing him in self-defense. Yet, Stephen R. Shalom indeed endorses such a prohibition. I shall argue that all the examples (...) Shalom offers in support of his view are disanalogous to the case in question, and provide examples that are analogous and strongly suggest that Shalom’s claim leads to counter-intuitive implications. Moreover, I will provide a clear-cut case that demonstrates that Shalom cannot rely on a general principle prohibiting lethal violence against permissible violence. Thus, I conclude that Shalom has failed to provide a convincing argument in support of his case. (shrink)

I shall argue that in some wars both sides are (as a collective) justified, that is, they can both satisfy valid jus ad bellum requirements. Moreover, in some wars – but not in all – the individual soldiers on the unjustified side (that is, on the side without jus ad bellum) may nevertheless kill soldiers (and also civilians as a side-effect) on the justified side, even if the enemy soldiers always abide by jus in bello constraints. Traditional just war theory (...) and self-proclaimed “revisionist” just war theory think otherwise since the former focuses on the law enforcement or public authority justification for inflicting harm and the latter on the self-defense justification. These are both intrinsically asymmetrical justifications: there is no justified self-defense (properly understood) against justified self-defense, nor is there justified law-enforcement against justified law-enforcement. However, there can, as I will show, be justified self-defense against force that is justified by a necessity justification, and there can be force justified by a necessity justification being used against force that is also justified by a necessity justification. The necessity justification is not intrinsically asymmetrical, and it is an indispensable justification in the context of war. Moreover, with regard to some forms of inflicting harm on others one may give special weight to one’s own interests and the interests of those to whom one has special responsibilities when assessing the proportionality of those acts. That is, the proportionality calculation may be agent-relative. This is in particular so in the case of foreseeably preventing innocent and non-threatening people from being saved (for instance, by shooting down a tactical bomber who would have saved them by destroying an ammunitions factory) but less so in the case of the intentional or foreseeable direct harming of innocent and non-threatening people (dropping bombs on people standing near an ammunitions factory). In the light of these considerations, I will then answer the question as to when soldiers may justifiably participate in war (and when not). (shrink)

Helen Frowe has recently offered what she calls a “practical” account of self-defense. Her account is supposed to be practical by being subjectivist about permissibility and objectivist about liability. I shall argue here that Frowe first makes up a problem that does not exist and then fails to solve it. To wit, her claim that objectivist accounts of permissibility cannot be action-guiding is wrong; and her own account of permissibility actually retains an objectivist (in the relevant sense) element. In addition, (...) her attempt to restrict subjectivism primarily to “urgent” situations like self-defense contradicts her own point of departure and is either incoherent or futile. Finally, the only actual whole-heartedly objectivist account she criticizes is an easy target; while those objectivist accounts one finds in certain Western European jurisdictions are immune to her criticisms. Those accounts are also clearly superior to hers in terms of action-guidingness. (shrink)

It is typically assumed that while we know other people’s mental states by observing and interpreting their behavior, we know our own mental states by introspection, i.e., without interpreting ourselves. In his latest book, The opacity of mind: An integrative theory of self-knowledge, Peter Carruthers (2011) argues against this assumption. He holds that findings from across the cognitive sciences strongly suggest that self-knowledge of conscious propositional attitudes such as intentions, judgments, and decisions involves a swift and unconscious process of self-interpretation (...) that utilizes the same sensory channels that we employ when working out other people’s mental states. I provide an overview of Carruthers’ book before discussing a pathological case that challenges his account of self-knowledge and mentioning empirical evidence that undermines his use of a particular kind of data in his case against introspection of conscious attitudes.

The paper briefly summarises and critiques Tomasello’s A Natural History of Human Thinking. After offering an overview of the book, the paper focusses on one particular part of Tomasello’s proposal on the evolution of uniquely human thinking and raises two points of criticism against it. One of them concerns his notion of thinking. The other pertains to empirical findings on egocentric biases in communication.

Demographic diversity might often be present in a group without group members noticing it. What are the epistemic effects if they do? Philosophers and social scientists have recently argued that when individuals detect demographic diversity in their group, this can result in epistemic benefits even if that diversity doesn’t involve cognitive differences. Here I critically discuss research advocating this proposal, introduce a distinction between two types of detection of demographic diversity, and apply this distinction to the theorizing on diversity in (...) science. Focusing on ‘invisible’ diversity (i.e., differences in, e.g., LGBTQ+, religious, or political orientation), I argue that in one common kind of group in science, if group members have full insight into their group’s diversity, this is likely to create epistemic costs. These costs can be avoided and epistemic benefits gained if group members only partly detect their group’s diversity. There is thus an epistemic reason for context-dependent limitations on scientists’ insight into the diversity of their group. (shrink)

Suppose we know our own attitudes, e.g. judgments and decisions, only by unconsciously interpreting ourselves. Would this undermine the assumption that there are conscious attitudes? Carruthers has argued that if the mentioned view of selfknowledge is combined with either of the two most common approaches to consciousness, i.e. the higher-order state account or the global workspace theory , then the conjunction of these theories implies that there are no conscious attitudes. I shall show that Carruthers' argument against the existence of (...) conscious attitudes doesn't succeed, and mention studies on autism and logical reasoning under cognitive load that suggest that there are conscious attitudes.

Many authors writing about global justice seem to take national responsibility more or less for granted. Most of them, however, offer very little argument for their position. One of the few exceptions is David Miller. He offers two models of collective responsibility: the like-minded group model and the cooperative practice model. While some authors have criticized whether these two models are applicable to nations, as Miller intends, my criticism is more radical: I argue that these two models fail as accounts (...) of collective responsibility as such. This result should not surprise us (liberals): there simply is no such thing as collective responsibility (in a strict sense), there is only individual responsibility. Thus individuals are not automatically responsible for the actions of their groups, nations or states, not even if they do not actively dissociate themselves from those actions. (shrink)

Thomas Pogge labels the idea that each person owes each other person equal respect and concern ‘ethical cosmopolitanism’ and correctly states that it is a ‘non-starter’. He offers as an allegedly more convincing cosmopolitan alternative his ‘social justice cosmopolitanism’. I shall argue that this alternative fails for pretty much the same reasons that ‘ethical cosmopolitanism’ fails. In addition, I will show that Pogge's definition of cosmopolitanism is misleading, since it actually applies to ethical cosmopolitanism and not to social justice cosmopolitanism. (...) This means that cosmopolitanism as defined by Pogge is wrong in the light of his own arguments and that Pogge is not even a cosmopolitan in the sense of his own definition. I will further show that he is also not a cosmopolitan if cosmopolitanism is defined as a philosophical position involving the claim that state borders have no fundamental moral significance.

Garrett Cullity concedes that saving a drowning child from a shallow pond at little cost to oneself is not actually analogous to giving money to a poverty relief organization like Oxfam. The question then arises whether this objection is fatal to Peters Singer's argument for a duty of assistance or whether it can be saved anyway. Cullity argues that not saving the drowning child and not giving money to organizations like Oxfam are still morally analogous, that is, not giving money (...) to organizations like Oxfam is morally nearly as bad as letting the child drown. I argue that Cullity's two arguments for this conclusion, an argument from "transitivity" and an argument from collective responsibility, fail. (shrink)

Joanna Mary Firth and Jonathan Quong argue that both an instrumental account of liability to defensive harm, according to which an aggressor can only be liable to defensive harms that are necessary to avert the threat he poses, and a purely noninstrumental account which completely jettisons the necessity condition, lead to very counterintuitive implications. To remedy this situation, they offer a “pluralist” account and base it on a distinction between “agency rights” and a “humanitarian right.” I argue, first, that this (...) distinction is spurious; second, that the conclusions they draw from this distinction do not cohere with its premises; third, that even if one granted the distinction, Firth’s and Quong’s implicit premise that you can forfeit your agency rights but not your “humanitarian right” is unwarranted; fourth, that their attempt to mitigate the counterintuitive implications of their own account in the Rape case relies on mistaken ad-hoc assumptions; fifth, that even if they were successful in somewhat mitigating said counterintuitive implications, they would still not be able to entirely avoid them; and sixth, that even in the unlikely case that none of these previous five critical points are correct, Firth and Quong still fail to establish that aggressors can be liable to unnecessary defensive harm since they fail to establish that unnecessary harm can ever be defensive in the first place.

Christopher J. Finlay claims “that a principle of moral or legitimate authority is necessary in just war theory for evaluating properly the justifiability of violence by non-state entities when they claim to act on behalf of the victims of rights violations and political injustice.” In particular, he argues that states, unlike non-state actors, possess what he calls “Lesser Moral Authority.” This authority allegedly enables states to invoke “the War Convention,” which in turn entitles even individual soldiers on the aggressive side (...) to use military violence against soldiers defending the victim state. Non-state actors, in contrast, have to fulfill more stringent requirements. If they do not, then even their attacks on military personnel can properly be called "terrorist." In the following I will argue that Finlay’s attempt to show the importance of the legitimate authority criterion of just war theory and to demonstrate that non-state violence has to satisfy heavier burdens of justification than state violence fails for a number of reasons: his claim that defenders would wrong victims if they defended them against their will is mistaken, he overlooks the fact that non-state agents need not claim to fight on someone’s behalf, the full moral authority he mentions is redundant, the powers he ascribes to “Lesser Moral Authority” are, depending on interpretation, either morally irrelevant or nonexistent, and his claim that granting states “Lesser Moral Authority” is beneficial from a “moral pragmatic” point of view while granting the same authority to non-state actors is not, is unwarranted.

Is there is a moral obligation to militarily intervene in another state to stop a genocide from happening (if this can be done with proportionate force)? My answer is that under exceptional circumstances a state or even a non-state actor might have a duty to stop a genocide (for example if these actors have promised to do so), but under most circumstances there is no such obligation. To wit, “humanity,” states, collectives, and individuals do not have an obligation to make (...) such promises in the first place or to create institutions that would impose a legal obligation of intervention upon them. Nor do states or persons or humanity “collectively” have – originally, without specifically creating such duties by contracts or promises – any pro tanto or special duties to save strangers at considerable cost to themselves or their own citizens (including their soldiers). That is, these costs do not merely override a duty to intervene, but rather there is no such duty to begin with – as shown by the fact that in such cases of non-intervention agents would not owe those they let die any compensation: if I do not save someone’s life because saving him would have cost me my arm or would have come with a high risk of losing my own life or would have forced me to kill innocent bystanders, I do not owe this person compensation. Thus the point of this chapter is that there is no “natural” or “general” or “original” duty to militarily intervene (or to create a legal obligation) to stop a genocide. I will consider and refute a number of arguments to the contrary, for example by Lango, Tan, and Pattison. (shrink)

What one is ultimately interested in with regard to ‘just cause’ is whether a specific war, actual or potential, is justified. I call this ‘the applied question’. Answering this question requires knowing the empirical facts on the ground. However, an answer to the applied question regarding a specific war requires a prior answer to some more general questions, both descriptive and normative. These questions are: What kind of thing is a ‘just cause’ for war (an aim, an injury or wrong (...) suffered, or something different altogether)? I call this ‘the formal question’. Then there is what I call the ‘the general substantive question’. Depending on the previous answer to the formal question, the general substantive question can be formulated as: ‘Which causes are just?’ or as ‘Under what conditions is there a just cause?’ A final question, which has recently elicited increased interest, is what I call ‘the question of timing’: does the ‘just cause’ criterion only apply to the initiation of a war or also to the continuation of a war, that is, can a war that had a just cause at the beginning lose it at some point in its course (and vice versa)? I argue that a just cause is a state of affairs. Moreover, the criterion of just cause is not independent of proportionality and other valid jus ad bellum criteria. One cannot know whether there is a just cause without knowing whether the other (valid) criteria (apart from ‘right intention’) are satisfied; and this account has certain theoretical and practical advantages. As regards the general substantive question, I argue that all kinds of aims can, in principle, be legitimately pursued by means of war, even aims that might sound dubious at first, like vengeance or the search for glory. Thus, the pursuit of such aims does not make the war disproportionate or deprive it of just cause. As regards the question of timing, I argue that the criteria of jus ad bellum apply throughout the war, not only at the point of its initiation. While starting a war at t1 might be justified, continuing it at time t2 might be unjustified (and vice versa), and this insight does not require an addition to jus ad bellum but is already contained in it.

McMahan’s own example of a symmetrical defense case, namely his tactical bomber example, opens the door wide open for soldiers to defend their fellow-citizens (on grounds of their special obligations towards them) even if as part of this defense they target non-liable soldiers. So the soldiers on both sides would be permitted to kill each other and, given how McMahan defines “justification,” they would also be justified in doing so and hence not be liable. Thus, we arrive, against McMahan’s intentions, (...) at a moral equality of combatants. In addition, his own account of liability cannot deal adequately with symmetrical defense cases in the first place. This undermines his presupposition that justification defeats liability, which is central to his defense of the moral inequality of combatants. I shall argue that McMahan’s attempts to counter these objections fail and that therefore his general claim of the moral inequality of combatants remains unpersuasive. (shrink)

Massimo Renzo has recently offered a theory of legitimacy that attempts to ground the state’s right to rule on the assumption that people in the state of nature pose an unjust threat to each other and can therefore, in self-defense, be forced to enter the state, that is, to become subject to its authority. I argue that depending on how “unjust threat” is interpreted in Renzo’s self-defense argument for the authority of the state, either his premise that “those who pose (...) an unjust threat to others can be justifiably coerced in self-defense, at least when they are morally responsible for posing the threat,” or his premise that “would-be independents pose an unjust threat to those living next to them in the state of nature,” or both of them are wrong. I further argue that his premise that would-be independents pose an unjust threat by refusing to enter the state is also mistaken. Refusing to enter the state, that is, refusing to be subject to the authority of the state, is no threat at all, and hence coercing people into entering the state is no means of self-defense and incapable of enhancing security. Renzo’s deduction of state authority from the right to self-defense fails. (shrink)

P.J. Markie tries to solve the so-called particularity problem of natural duty accounts of political obligation, a problem which seems to make natural duty accounts implausible. I argue that Markie at best “dissolves” the problem: while his own natural duty account of political obligation still does not succeed in ensuring particularity, this is not an implausible but an entirely plausible implication of his account, thanks to the weakness of his concept of political obligation. The price for this, however, is that (...) his approach has little to do with political obligation and the particularity problem as discussed in the literature. (shrink)

In a recent paper, Jonathan Quong tries to offer further support for “the proposition that there are sometimes agent-relative prerogatives to harm nonliable persons.” In this brief paper, I will demonstrate that Quong’s argument implicitly relies on the premise that the violinist in Thomson’s famous example has a right not to be unplugged. Yet, first, Quong provides no argument in support of this premise; and second, the premise is clearly wrong. Moreover, throughout his paper Quong just question-beggingly and without argument (...) assumes that one cannot lose rights in other ways than by one’s own responsible action. I conclude that Quong has failed to provide further support for his thesis. (shrink)

This paper argues that there is a significant moral difference between force applied against (imminent) attackers on the one hand and force applied against “threatening” people who are not (imminent) attackers on the other. Given that there is such a difference, one should not blur the lines by using the term “self-defense” (understood as including other-defense) for both uses of force. Rather, only the former is appropriately called self-defense, while for the latter, following German legal terminology, the term “justifying defensive (...) emergency” will be used here. The two justifications are not governed by the same criteria and thus lead to different results. The paper will proceed by providing first, in section (1), a brief sketch of the contours of the self-defense justification, putting particular emphasis on the necessity criterion. On the account presented here, the necessity criterion of the self-defense justification is particularly harsh on the aggressor (and thus not to be interpreted as literally requiring the employment of “the mildest means”) and its applicability is only triggered by an (imminent) attack, not by other kinds of threats. Section (2) will then further explain the differences between self-defense and justifying defensive emergency. A particularly important difference is that people who are subjected to justified self-defense cannot permissibly defend themselves, while people who are subjected to (extremely harmful or even lethal) justified defensive emergency measures can. Thus, in this latter case we have a “moral equality” (of sorts) of the involved parties: they can permissibly use force against each other. Section (3) will list and defend some conditions that a successful argument against the imminence requirement of the self-defense justification has to satisfy. In the light of these conditions, sections (4) to (7) will discuss a number of objections that have been adduced against the imminence requirement as well as proposals that have been made in support of alternative accounts. It will be argued that all these objections and proposals fail. Section (8) will provide a number of thought experiments in support of the claim that the harsh necessity criterion of the self-defense justification is only triggered by imminence while force against non-imminent threats can be justified with the help of the justifying emergency exemption, as well as for the claim that the justifying emergency exemption puts the person using preventive force against non-imminent threats on a shorter leash and makes him liable to counter-measures. Section (9) will explain the rationale for tying the applicability of the harsh necessity criterion of the self-defense justification to imminent attacks. Section (10) will discuss some special cases and show why they do not undermine the normative validity of this tie. (shrink)

Rights forfeiture or liability are not a path to the permissibility of self-defense (not even barring extraordinary circumstances), and the necessity condition is not intrinsic to justified self-defense. Rather, necessity in the context of justification must be distinguished from necessity in the context of rights forfeiture. While innocent aggressors only forfeit their right against necessary self-defense, culpable aggressors also forfeit, on grounds of a principle of reciprocity, certain rights against unnecessary self-defense. Yet, while culpable aggressors would therefore not be wronged (...) by certain unnecessary defensive means, the use of such means against them would still not be justified. The underlying rationale of this necessity requirement lies not in the rights of the aggressor, but in an agent-relative requirement to take fair precautions against violating the rights of the innocent. This concern is also expressed in the necessity criterion defended and formulated in this paper, which is very harsh on aggressors. To wit, the necessity condition for justified self-defense must not be interpreted as requiring the employment of literally the least harmful means or of means that the defender reasonably believes to be, literally, the least harmful ones. What he must believe about the properties and possible effects of the means he employs is something that is much less demanding. Finally, the necessity condition of justified self-defense is also harsh (on the aggressor) in not implying a “success condition” worth its name. (shrink)

I argue that rights-forfeiture by itself is no path to permissibility at all (even barring special circumstances), neither in the case of self-defense nor in the case of punishment. The limiting conditions of self-defense, for instance – necessity, proportionality (or no gross disproportionality), and the subjective element – are different in the context of forfeiture than in the context of justification (and might even be absent in the former context). In particular, I argue that a culpable aggressor, unlike an innocent (...) aggressor, forfeits rights against proportionate defense, including unnecessary defense (as well as rights against the infliction of proportionate non-defensive harm). Yet, I demonstrate that this stance need not lead to the abandonment of the necessity condition of justified self-defense in the case of a culpable aggressor. Since justification and liability are not the same, there is no reason to assume that the necessity condition of justified self-defense must be explained under an appeal to the aggressor’s rights. Parallel arguments apply to the other limiting conditions of permissible self-defense as well as to the limiting conditions of permissible punishment. Accordingly, I also sketch alternative explanations of the proportionality requirement and the subjective element. All these alternative explanations appeal to a principle of precaution: instead of explaining the unjustifiability of unnecessarily harming a culpable attacker or wrongdoer by an appeal to the rights of the attacker or wrongdoer himself, one can also, and better, explain it by a requirement to take reasonable precautions against violating the rights of innocent people.

In a recent paper, McMahan argues that his ‘Responsibility Account’, according to which ‘the criterion of liability to attack in war is moral responsibility for an objectively unjustified threat of harm’, can meet the challenge of explaining why most combatants on the unjustified side of a war are liable to attack while most civilians (even on the unjustified side) are not. It should be added, however, that in the light of his rejection of the ‘moral equality of combatants’, McMahan would (...) also have to explain why combatants on the justified side of a war are not liable to attack. I will argue here that McMahan does not succeed in meeting these challenges. (shrink)

Anna Stilz claims that citizens of democratic states bear “task responsibility” to repair unjust harms done by their states. I will argue that the only situation in which Stilz’s argument for such “task responsibility” is not redundant, given her own premises, is a situation where the state leaves it up to the citizens whether to indemnify others for the harms done by the state. I will also show that Stilz’s “authorization view” rests on an unwarranted and implausible assumption (which I (...) call “the authorization principle”) about authorization and political obligation, and that this problem cannot be remedied by limiting the account to democratic states. I will then briefly turn to Pasternak’s account of citizen responsibility for state action and argue that it suffers from two deficiencies: first, she equates group membership with collective action, and second, she does not provide any explanation as to why citizens should incur liability for the acts of their state under the four conditions she highlights. I conclude that neither Stilz nor Pasternak succeed in showing that at least citizens of democratic states are liable (barring very special circumstances) for the acts of their states. (shrink)

In a recent article Yvonne Chiu argues that nonuniformed combat is impermissible. However, her argument that by fighting without uniforms nonuniformed guerillas coerce civilians into participating in the armed conflict and thus into surrendering their immunity (their right not to be attacked) fails: there is no coercion, no participation, and no surrendering of immunity. Yet even if this argument of hers were correct, it would still not show that such “coercion” would amount to a rights infringement. Moreover, even if it (...) did, there are examples that show that such an infringement would sometimes be perfectly justified. Finally, if she were right that forcing civilians into a moral position that they have not accepted or chosen is absolutely wrong, then this would affect the moral status of uniformed combatants no less than it would affect the moral status of nonuniformed ones.
