    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

    What Is War—And Can a Lone Individual Wage One?
    International Journal of Applied Philosophy 23 (1): 133-150. 2009.
    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 wa…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

    Moral Ambiguities in the Bombing of Monte Cassino

    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 …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

    The Moral Equality of Modern Combatants and the Myth of Justified War
    Theoretical and Applied Ethics 1 (4): 35-44. 2012.
    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, pri…Read more

    Stephen Kershnar’s main argument in Gratitude toward Veterans is that Americans should not be very grateful towards veterans. More precisely, he not only argues that veterans do not deserve the gratitude that many Americans offer them, but also that it is morally objectionable to be grateful towards them. His argument is applicable to war veterans generally, not only to those in the USA. Yet, it does have specific relevance to the United States given that, as Kershnar demonstrates, public gratit…Read more

    On the Ethics of Torture
    State University of New York Press. 2013.
    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 philoso…Read more

    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 questio…Read more

    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 indiv…Read more

    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) ele…Read more

    Benbaji on killing in war and 'the war convention'
    Philosophical Quarterly 60 (240): 616-623. 2010.
    Yitzhak Benbaji defends the view that soldiers on both the ‘just’ and the ‘unjust’ side in a war have the same liberty right to kill one another, because soldiers have ‘tacitly accepted’ the egalitarian laws of war and thereby waived their moral rights not to be attacked. I argue that soldiers on the ‘just’ side have not accepted the egalitarian laws of war; even if they had, they would not thereby have waived their moral rights not to be attacked. Moreover, the egalitarian laws of war and ‘the …Read more

    Why We Shouldn’t Reject Conflicts: A Critique of Tadros
    Res Publica 20 (3): 315-322. 2014.
    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 lig…Read more

    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 infringe…Read more

    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 agg…Read more
