In this book Uwe Steinhoff describes and explains the basic tenets of just war theory and gives a precise, succinct and highly critical account of its present status and of the most important and controversial current debates surrounding it. Rejecting certain in effect medieval assumptions of traditional just war theory and advancing a liberal outlook, Steinhoff argues that every single individual is a legitimate authority and has under certain circumstances the right to declare war on others or the state. He (...) also argues that the just cause cannot be established independently of the other criteria of jus ad bellum (the justification of entering a war), except for right intention, which he interprets more leniently than the tradition does. Turning to jus in bello (which governs the conduct of a war) he criticizes the Doctrine of Double Effect and concludes that insofar as wars kill innocents, and be it as "collateral damage", they cannot be just but at best justified as the lesser evil. Steinhoff gives particular attention to the question why soldiers, allegedly, are legitimate targets and civilians not. Discussing four approaches to the explanation of the difference he argues that the four principles underlying them all need to be taken into account and outlines how their weighing can proceed if applied to concrete cases. The resulting approach does not square the distinction between legitimate and illegitimate targets with the distinction between soldiers and civilians, which has extremely important consequences for the conduct of war. Finally, Steinhoff analyses the concept of terrorism and argues that some forms of "terrorism" are actually not terrorism at all and that even terrorism proper can under certain circumstances be justified.

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.

Demographic diversity might often be present in a group without group members noticing it. What are the epistemic effects if they do? Several 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 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)

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)

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)

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.

This book offers a philosophical analysis of the moral and legal justifications for the use of force. While the book focuses on the ethics self-defense, it also explores its relation to lesser evil justifications, public authority, the justification of punishment, and the ethics of war. Steinhoff’s account of the moral use of force covers a wide range of topics, including the nature of justification in general, the precise elements of different justifications, the logic of claim- and liberty-rights and of rights (...) forfeiture, the value of human life and its limits, and the principles of reciprocity and precaution. While the author’s analysis is primarily philosophical, it is informed by a metaethical stance that also places heavy emphasis on existing law and legal scholarship. In doing so, the book appeals to widely shared moral intuitions, precepts, and concepts grounded in criminal law. Self-Defense, Necessity, and Punishment offers the most comprehensive and systematic account of the ethics of self-defense. It will be of interest to scholars and graduate students working in applied ethics and moral philosophy, philosophy of law, and political philosophy. (shrink)

This book is intended as a comprehensive defense of psycho-physical dualism. It gives answers to the question of what dualism may consist in, and inquires into the broadly cultural motivation behind accepting dualism or its opponent physicalism. Arguments for dualism, among them strengthened versions of the famous classical arguments, are presented and defended against objections. Moreover, the various general objections to dualism are criticized in detail, for example, the allegation that dualism is of an anti-scientific nature. The book issues into (...) developing the outlines of a dualistic theory of consciousness and agency. The theory outlined is not only compatible with science but actually connects with it. It offers a unified perspective on the phenomenon of conscious life and may serve as a basis for a general ethics regarding all conscious living beings. (shrink)

A detailed, clear, and comprehensive overview of the current philosophical debate on. The question of when, and under what circumstances, the practice of torture might be justified has received a great deal of attention in the last decade in both academia and in the popular media. Many of these discussions are, however, one-sided with other perspectives either ignored or quickly dismissed with minimal argument. In On the Ethics of Torture, Uwe Steinhoff provides a complete account of the philosophical debate surrounding (...) this highly contentious subject. Steinhoff’s position is that torture is sometimes, under certain narrowly circumscribed conditions, justified, basing his argument on the right to self-defense. His position differs from that of other authors who, using other philosophical justifications, would permit torture under a wider set of conditions. After having given the reader a thorough account of the main arguments for permitting torture under certain circumstances, Steinhoff explains and addresses the many objections that have been raised to employing torture under any circumstances. This is an indispensible work for anyone interested in one of the most controversial subjects of our times. (shrink)

Preface This book is about semantics and logic. More specifically, it is about the semantics and logic of natural language; and, even more specifically than ...

I argue in this paper that traditional just war theory did allow private, indeed even individual war, and that arguments in support of a legitimate authority criterion, let alone in support of the “priority” of this criterion, fail. I further argue that what motivates the insistence on “legitimate authority” is the assumption that doing away with this criterion will lead to chaos and anarchy. I demonstrate that the reasoning, if any, underlying this assumption is philosophically profoundly confused. The fact of (...) the matter is that wars need not necessarily be authorized by some higher authority (such as a king, president, or parliament) in order to be justified, and this moral fact does not need to chaos and anarchy. Accordingly, the criterion of legitimate authority cannot be relied on to delegitimate individual war, private war, guerrilla war, or even terrorism. Finally, I consider some other defenses of authorization and demonstrate that the “authorization” these accounts defend is either not needed for justification or already provided by other just war criteria or, indeed, entirely fictitious.

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)

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)

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)

In this paper we develop a theory of language meaning that represents scope ambiguities by underspecified structures. The set of possible meanings of a sentence, or text is determined by a set of meta-level constraints that restricts the class of semantic representations appropriately. Thus the way ambiguities are represented does not correspond to any of the usual concepts of formalizing ambiguities by means of disjunctions (of completely specified structures). A sound and complete proof theory is provided that relates these structures (...) directly, without considering cases. (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)

abstract Can torture be morally justified? I shall criticise arguments that have been adduced against torture and demonstrate that torture can be justified more easily than most philosophers dealing with the question are prepared to admit. It can be justified not only in ticking nuclear bomb cases but also in less spectacular ticking bomb cases and even in the so‐called Dirty Harry cases. There is no morally relevant difference between self‐defensive killing of a culpable aggressor and torturing someone who is (...) culpable of a deadly threat that can be averted only by torturing him. Nevertheless, I shall argue that torture should not be institutionalised, for example by torture warrants. (shrink)

I argue that the often-heard claim that all serious present-day political philosophers subscribe to the principle of equal respect and concern or to the doctrine of equal moral status or are in some other fundamental sense egalitarians is wrong. Also wrong is the further claim that the usual methods currently used in political philosophy presuppose basic equality. I further argue that liberal egalitarianism itself is wrong. There is no universal duty “of equal respect and concern” towards every person, for one (...) does not owe one’s nice sister and a serial rapist equal respect and concern. There is also no duty of the state to respect all citizens equally, for a state need not be equally concerned about murderous criminals on the one hand and their innocent victims on the other. The potential maneuver of saving liberal egalitarianism by claiming that people have equal rights is unsuccessful. Human beings clearly do not have equal rights, nor are they born with equal rights; and merely having an equality of some rights, for example of “basic” or human ones, would not suffice for egalitarianism. Appeals to “recognition respect” and related concepts are also to no avail. Trying to go back still a step further and to claim that certain rights inequalities or justified discriminatory rules are themselves “grounded” in equal respect and concern at some deeper, norm-generating level (like, for example, the original position or a discourse-ethical principle of justification) is also futile. Finally, I argue that the “This is not what we mean”-strategy of escaping the above arguments reduces egalitarianism to triviality and empty rhetoric. Liberal egalitarianism should be abandoned.

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.

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)

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)

I focus on the question as to what rationale could possibly underlie the doctrine of double effect or related principles. I first briefly review the correct critiques of the claim that people who intend some evil as a means to a good must be “guided by evil,” and that this is allegedly always wrong. I then argue that Quinn’s claim that violations of the DDE express certain negative attitudes of the agent and that agents violating the DDE must make an (...) additional morally problematic presumption regarding their victims is mistaken. Tadros claims that an agent violating the means principle must force his victims to adopt his goals. I demonstrate that the difference Tadros tries to construe between an agent inflicting intended harm and an agent inflicting merely foreseen harm is non-existent. Sarch’s official rationale for the DDE also fails to distinguish harming as a means from side-effect harming, and reformulations of his rationale that suggest themselves run into severe problems. Walen’s defense of the means principle in terms of the “restricting claims principle” and Øverland’s appeal to “moral obstacles” are susceptible to counter-examples and appear to be question-begging. Recently, Walen has offered a revised formulation of his Restricting Claims Principle, claiming that it overcomes counter-examples and explains the means principle. I will argue that it contradicts the means principle and does not overcome the counter-examples. Thus I conclude that so far we are still left without a reasonable rationale for the DDE or related principles. (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 present-day political and moral philosophy the idea that all persons are in some way moral equals is an almost universal premise, with its defenders often claiming that philosophical positions that reject the principle of equal respect and concern do not deserve to be taken seriously. This has led to relatively few attempts to clarify, or indeed justify, 'basic equality' and the principle of equal respect and concern. Such clarification and justification, however, would be direly needed. After all, the ideas, (...) for instance, that Adolf Hitler and Nelson Mandela have equal moral worth, or that a rape victim owes equal respect and concern to both her rapist and to her own caring brother, seem to be utterly implausible. Thus, if someone insists on the truth of such ideas, he or she owes his or her audience an explanation. The authors in this volume - which breaks new ground by engaging egalitarians and anti-egalitarians in a genuine dialogue - attempt to shed light into the dark. They try to clarify the concepts of "basic equality", "equal moral worth","equal respect and concern", "dignity," etc; and they try to justify-or to refute-the resulting clarified doctrines. The volume thus demonstrates that the claim that all persons have equal moral worth, are owed equal concern and respect, or have the same rights is anything but obvious. This finding has not only significant philosophical but also political implications. (shrink)

The paper provides new perspectives for a dualistic conception of mental causation by putting causation that originates in a nonphysical self into an evolutionary perspective. Nonphysical causation of this type - free agency -, together with nonphysical consciousness, is regarded as being not only compatible with physics, but also as having a natural place in nature. It is described how free agency can work, on the basis of the brain, and how it can be compatible with the result of the (...) Libet-experiment. The necessary condition for the existence of free agency is that the physical macro-world is indeterministic to a degree that is relevant for living beings, that is, for their survival and well-being. From an evolutionary point of view, and on the basis of the facts of consciousness, it is more likely than not that this condition is in fact fulfilled. (shrink)

Answer-set programming (ASP) has emerged as a declarative programming paradigm where problems are encoded as logic programs, such that the so-called answer sets of theses programs represent the solutions of the encoded problem. The efficiency of the latest ASP solvers reached a state that makes them applicable for problems of practical importance. Consequently, problems from many different areas, including diagnosis, data integration, and graph theory, have been successfully tackled via ASP. In this work, we present such ASP-encodings for problems associated (...) to abstract argumentation frameworks (AFs) and generalisations thereof. Our encodings are formulated as fixed queries, such that the input is the only part depending on the actual AF to process. We illustrate the functioning of this approach, which is underlying a new argumentation system called ASPARTIX in detail and show its adequacy in terms of computational complexity. (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.

Language- and music-readiness are demonstrated as related within comparative neuroprimatology by elaborating three hypotheses concerning music-readiness : The rhythm-first hypothesis, the combinatoriality hypothesis, and the socio-affect-cohesion hypothesis. MR-1 states that rhythm precedes evolutionarily melody and tonality. MR-2 states that complex imitation and fractionation within the expanding spiral of the mirror system/complex imitation hypothesis lead to the combinatorial capacities of rhythm necessary for building up a musical lexicon and complex structures; and rhythm, in connection with repetition and variation, scaffolds both musical (...) form and content. MR-3 states that music’s main evolutionary function is to self-induce affective states in individuals to cope with distress; rhythm, in particular isochrony, provides a temporal framework to support movement synchronization, inducing shared affective states in group members, which in turn enhances group cohesion. This document reviews current behavioural and neurocognitive research relevant to the comparative neuroprimatology of music-readiness. It further proposes to extend MS/CIH through the evolution of the relationship of the language- and music-ready brain, by comparing “affective rhythm” and prosody – i.e. by comparatively approaching the language- and music-emotion link in neuroprimatology.

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.

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.

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)
