this paper advances a novel account of part of what justifies killing in war, grounded in the duties we owe to our loved ones to protect them from the severe harms with which war threatens them. It discusses the foundations of associative duties, then identifies the sorts of relationships, and the specific duties that they ground, which can be relevant to the ethics of war. It explains how those associa- tive duties can justify killing in theory—in particular how they can (...) justify overrid- ing the rights to life of some of those who must be killed to win a war. It then shows how these duties can be operationalised in practice: first, showing how soldiers who fight on behalf of their community can act on reasons that apply to the members of that community; second, showing that the argument from associative duties does not prove too much—in particular, that it does not license the intentional killing of noncombatants in war.

Abstract The article addresses three aspects of the humanitarian intervention doctrine. It argues, first, that the value of sovereignty rests on the justified social processes of the target state ? the horizontal contract. Foreign interventions, even when otherwise justified, must respect the horizontal contract. In contrast, morally objectionable social processes (such as the subjection of women) are not protected by sovereignty (intervention, of course, may be banned for other reasons). In addition, tyrants have no moral protection against interventions directed at (...) them. Second, the article addresses the internal legitimacy of humanitarian intervention. It concludes that the liberal state may only use voluntary soldiers (either the voluntary army or mercenaries) to conduct humanitarian intervention. Conscription for that purpose is not permissible. The article shows that the long-standing criticism of mercenaries stems from a romantic prejudice and is thus unfair. Third, the article makes a distinction between intention (the determination to perform an action) and motive (a further goal that the agent seeks with that action) and shows that only intention is relevant for humanitarian intervention. A justified humanitarian intervention requires the intention to liberate the victims, but not necessarily a good further motive. It shows how mainstream doctrine has impermissibly confused the two concepts. (shrink)

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

Since it appeared in 1971, John Rawls's A Theory of Justice has become a classic. The author has now revised the original edition to clear up a number of difficulties he and others have found in the original book. Rawls aims to express an essential part of the common core of the democratic tradition--justice as fairness--and to provide an alternative to utilitarianism, which had dominated the Anglo-Saxon tradition of political thought since the nineteenth century. Rawls substitutes the ideal of the (...) social contract as a more satisfactory account of the basic rights and liberties of citizens as free and equal persons. "Each person," writes Rawls, "possesses an inviolability founded on justice that even the welfare of society as a whole cannot override." Advancing the ideas of Rousseau, Kant, Emerson, and Lincoln, Rawls's theory is as powerful today as it was when first published. (shrink)

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

The principle of absolute sovereignty may have been consigned to history, but a strong presumption against foreign intervention seems to have been left in its stead. On the dominant view, only massacre and ethnic cleansing justify armed intervention, these harms must be already occurring or imminent, and the prudential constraints on war must be satisfied. Each of these conditions has recently come under pressure. Those looking to defend the dominant view have typically done so by invoking international peace and stability, (...) or the value of communal self-determination. But the internal aspect of legitimacy has been overlooked in all of this. If a government insists on defending the human rights of foreigners, it must also be sure not to violate the rights of its own citizens in the process. I argue that the current presumption against humanitarian intervention cannot be substantially relaxed for internal reasons, or given the obligations that states owe to their own constituents.

Although military personnel are required to follow all legal orders, morally the traditional contract between soldier and state rests on shared assumptions about the purposes for which national militaries will and will not be used.

An “optional war” is a war that a state is permitted but not required to wage. Are there any such wars? This article assesses the two most promising arguments for optional war. (1) Permissible humanitarian wars can be so costly for soldiers and taxpayers that states are not be required them. (2) Wars of national self-defense can be discretionary: states can sometimes choose whether or not to defend themselves. The article refutes both arguments. Pace (1), states should not wage wars (...) when the costs of doing so are overly burdensome. Pace (2), states are required to resist aggression whenever they are morally permitted to do so.

This article reconstructs the political motivation argument against cosmopolitanism, according to which the extension of social justice beyond bounded communities would be motivationally unstable, and thus unjustified. It does so through an analysis of the stability problem, and a reconstruction of the three most prominent anti-cosmopolitan arguments—Rawlsian statism, liberal nationalism, and civic republicanism—as solutions to this problem. It then examines, and rejects, three prominent objections, each denying a different level of the argument. The article concludes that the civic republican version (...) of the argument is the most plausible, and implications for cosmopolitanism are considered. (shrink)

Each of us begins with a set of concerns, desires, and interests of our own, and each of us can recognize that the same is true of others. We can then remove ourselves in thought from our particular position in the world and think simply of all those people, without singling out as I the one we happen to be. From this abstracted impersonal standpoint, the content and character of different individual standpoints remain unchanged. The impersonal standpoint plays an essential (...) role in the evaluation of political institutions. Any political theory that aspires to moral decency must try to devise and justify a form of institutional life, which answers to the real strength of impersonal values while recognizing that they are not all we have to reckon with.

What, if anything, can realism say about the normative conditions of political legitimacy? Must a realist political theory accept that the ability to successfully employ coercive power is equivalent to the right to rule, or can it incorporate normative criteria for legitimacy but without collapsing into a form of moralism? While several critics argue that realism fails to adequately differentiate itself from moralism or that it cannot coherently appeal to normative values so as to distinguish might from right, this article (...) seeks to help develop a realist account of legitimacy by demonstrating how it can successfully and stably occupy this position between moralism and Realpolitik. Through this discussion, however, the article also argues that political rule necessitates the use of coercive power which is (at best) imperfectly legitimated, and that this blurs the distinction between politics and successful domination which lies at the heart of many recent accounts of political realism. In at least this sense, realism retains important and under-acknowledged affinities to Realpolitik. (shrink)

The possibility of using private military and security companies to bolster the capacity to undertake intervention for human rights purposes has been increasingly debated. The focus of such discussions has, however, largely been on practical issues and the contingent problems posed by private force. By contrast, this article considers the principled case for privatising humanitarian intervention. It focuses on two central issues. First, does outsourcing humanitarian intervention to private military and security companies pose some fundamental, deeper problems in this context, (...) such as an abdication of a state's duties? Second, on the other hand, is there a case for preferring these firms to other, state-based agents of humanitarian intervention? For instance, given a state's duties to their own military personnel, should the use of private military and security contractors be preferred to regular soldiers for humanitarian intervention?
