    Saba Bazargan proposes a novel “hybrid” justification for the killing of minimally responsible threats (MRTs). His account allegedly combines two elements, namely “the complex account of liability” and “the lesser-evil discounting view.” I argue that Bazargan’s conclusion that minimally responsible threats can sometimes be killed as well as certain other conclusions that Bazargan regards as a particular advantage of his hybrid account are single-handedly generated by one element of the “hybrid a…Read more

    Truth vs. Rorty
    Philosophical Quarterly 47 (188): 358-361. 1997.
    In his article ‘Is Truth a Goal of Enquiry?’ Rorty claims that the difference between truth and justification makes no difference to practice. His argument for this is that assessment of truth and assessment of justification are the same activity. This argument is insufficient, for the difference to practice can be found elsewhere. I shall demonstrate that, and also show in which way this difference manifests itself in utility/risk calculations in which the risk is that a certain justified belie…Read more

    When May Soldiers Participate in War?
    International Theory 8 (2): 262-296. 2016.
    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” j…Read more

    Proportionality in Self-Defense
    The Journal of Ethics 21 (3): 263-289. 2017.
    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 …Read more

    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 ter…Read more

    In Defence of Guerrillas
    Diametros 23 84-103. 2010.
    This article examines the moral issues of guerrilla, and counter-guerrilla, warfare. Just war theorists who have studied the phenomenon tend to claim that the guerrilla tactic of wearing civilian clothes and hiding among the civilian population is rather difficult, if at all, to reconcile with the ius in bello principle of discrimination (the principle according to which combatants have to distinguish between combatants and non-combatants and may only target the former “directly”). I argue that …Read more

    Just Cause and the Continuous Application of Jus ad Bellum
    In and Eric Joseph Ritter Shannon Elizabeth Fyfe Larry May May, Shannon Elizabeth Fyfe & Eric Joseph Ritter (eds.), The Cambridge Handbook on Just War Theory, Cambridge University Press. forthcoming.
    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, o…Read more

    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. Afte…Read more

    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 f…Read more

    The Liability of Justified Attackers
    Ethical Theory and Moral Practice 19 (4): 1016-1030. 2016.
    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 ri…Read more

    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…Read more

    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 “t…Read more

    On the ethics of war and terrorism
    Oxford University Press. 2007.
    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…Read more

    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…Read more

    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 organizatio…Read more

    Über die unüberwundenen Begründungsdefizite der „Kritischen Theorie“ – Von Habermas zu Forst
    Zeitschrift für Kritische Sozialtheorie Und Philosophie 2 (1). 2015.
    In the first part of this paper I argue that there is hardly one correct step within the chains of arguments by which Habermas tries to substantiate his theory of communicative action, discourse ethics, and his theory of social order. In the second part of the paper I address Rainer Forst’s “principle of justification,” on which a “right to justification” is supposed to be based. I argue that Forst himself does not really justify his views but instead offers merely unwarranted stipulations. More…Read more

    Many philosophers have criticized John Rawls’s Law of Peoples. However, often these criticisms take it for granted that the moral conclusions drawn in A Theory of Justice are superior to those in the former book. In my view, however, Rawls comes to many of his 'conclusions' without too many actual inferences. More precisely, my argument here is that if one takes Rawls’s premises and the assumptions made about the original position(s) seriously and does in fact think them through to their logical…Read more

    Torture and Moral Integrity: A Philosophical Enquiry by Matthew H. Kramer
    Kennedy Institute of Ethics Journal 25 (4): 1-6. 2015.
    The blurb of Matthew Kramer’s book, Torture and Moral Integrity: A Philosophical Enquiry, states that the book “seeks to explain why interrogational and other types of torture are always and everywhere morally wrong.” This might give the prospective reader the impression that the book takes an absolutist stance against torture, but this impression would be misleading. The explanation of the discrepancy between the book’s self-presentation and what it is actually saying lies in the idiosyncratic …Read more

    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…Read more

    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 th…Read more

    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 right…Read more

    Just Cause and 'Right Intention'
    Journal of Military Ethics 13 (1): 32-48. 2014.
    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 th…Read more

    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 …Read more
