I argue that prioritarianism cannot be assessed in abstraction from an account of the measure of utility. Rather, the soundness of this view crucially depends on what counts as a greater, lesser, or equal increase in a person’s utility. In particular, prioritarianism cannot accommodate a normatively compelling measure of utility that is captured by the axioms of John von Neumann and Oskar Morgenstern’s expected utility theory. Nor can it accommodate a plausible and elegant generalization of this theory that has been offered in response to challenges to von Neumann and Morgenstern. This is, I think, a theoretically interesting and unexpected source of difficulty for prioritarianism, which I explore in this article.

Book review of McMahan J. "Killing in War." Oxford: Oxford University Press; 2009. --- Jeff McMahan’s "Killing in War" is, among many other things, a brief against the traditional just war doctrine of the moral equality of combatants – i.e. the doctrine that all combatants ‘have the same moral status, hence the same moral rights, immunities, and liabilities’, including ‘an equal right to kill’, irrespective of whether the war they fight is just or unjust.1 This book is a powerfully argued, nuanced, comprehensive, relentless and impassioned brief against this doctrine. It wages total war against it, eclipsing all past skirmishes. Yet, at the same time that he rejects the moral equality of combatants, McMahan affirms the ‘legal equality of combatants’, according to which ‘legal rights, liabilities, and immunities of combatants are unaffected by’ the justice or injustice of the war they fight. Not only does McMahan affirm that the legal equality of combatants holds as a matter of fact. He also affirms that such legal equality is morally justified at present. In this article, I shall expose and explore tensions that arise as the result of this uneasy combination of McMahan’s affirmation of the legal equality of combatants and his thoroughgoing rejection of their moral equality.

This chapter provides a defense of a type of occupational pension, known as “collective defined contribution”, which is based on the idea that it is possible to limit the employer’s liability to nothing more than a set contribution while retaining many of the benefits of the collectivization of risks of a traditional defined benefit pension. CDC can be defended against a freedom-based objection from the right via an appeal to the following Hobbesian voluntarist justification: CDC constitutes a “Leviathan of Leviathans” into which it is rational for workers to choose to associate in order to tame longevity and investment risks. CDC pensions that arise from and mirror existing income inequalities can also be defended against an egalitarian objection from the left, by demonstration that they can be grounded in Rawlsian principles of reciprocity and property-owning democracy

I assess G. A. Cohen's claim, which is central to his luck egalitarian account of distributive justice, that forcing others to pay for people's expensive indulgence is inegalitarian because it amounts to their exploitation. I argue that the forced subsidy of such indulgence may well be unfair, but any such unfairness fails to ground an egalitarian complaint. I conclude that Cohen's account of distributive justice has a non-egalitarian as well as an egalitarian aspect. Each impulse arises from an underlying commitment to fairness. Cohen's account of distributive justice is therefore one of justice as fairness

An argument against Parfit's view (in his chapter of Reasons and Persons on five mistakes in moral mathematics) that, rather than maximizing the difference one makes as an individual, one should join that group whose members together make the most positive difference in cases involving imperceptible benefits. It is shown how Parfit's defence of this view has the problematic implication either (1) that each outcome is less beneficial than itself or (2) that "less beneficial than" is not transitive.

Should egalitarian justice be qualified by an agent-relative prerogative to act on a preference for—and thereby in a manner that gives rise to or preserves a greater than equal share of the goods of life for—oneself, one's family, loved ones, or friends as compared with strangers? Although many would reply that the answer to this question must be ‘yes’, I shall argue here that the case for such a prerogative to depart from equality is much less far-reaching than one might think. I have in mind a prerogative to depart from a specific form of equality: namely, equality of opportunity for such advantages as resources or welfare. I mean to refer to the strong form of equal opportunity elaborated and defended by Richard Arneson and G. A. Cohen whereby, roughly speaking, two people have equal opportunity for advantage if they face the same choices and will end up at the same level of advantage if they make the same choices.

Michael Otsuka sets out to vindicate left-libertarianism, a political philosophy which combines stringent rights of control over one's own mind, body, and life with egalitarian rights of ownership of the world. Otsuka reclaims the ideas of John Locke from the libertarian Right, and shows how his Second Treatise of Government provides the theoretical foundations for a left-libertarianism which is both more libertarian and more egalitarian than the Kantian liberal theories of John Rawls and Thomas Nagel. Otsuka's libertarianism is founded on a right of self-ownership. Here he is at one with 'right-wing' libertarians, such as Robert Nozick, in endorsing the highly anti-paternalistic and anti-moralistic implications of this right. But he parts company with these libertarians in so far as he argues that such a right is compatible with a fully egalitarian principle of equal opportunity for welfare. In embracing this principle, his own version of left-libertarianism is more strongly egalitarian than others which are currently well known. Otsuka argues that an account of legitimate political authority based upon the free consent of each is strengthened by the adoption of such an egalitarian principle. He defends a pluralistic, decentralized ideal of political society as a confederation of voluntary associations. Part I of Libertarianism without Inequality concerns the natural rights of property in oneself and the world. Part II considers the natural rights of punishment and self-defence that form the basis for the government's authority to legislate and punish. Part III explores the nature and limits of the powers of governments which are created by the consensual transfer of the natural rights of the governed. Libertarianism without Inequality is a book which everyone interested in political theory should read

I defend an incompatibilist 'Principle of Avoidable Blame' according to which one is blameworthy for performing an act of a given type only if one could instead have behaved in a manner for which one would have been blameless. First, I demonstrate that this principle is resistant to Harry Frankfurt-type counterexample. Second, I present a positive argument for this principle that appeals to the relation of blame to the 'reactive attitude' of indignation. Finally, I argue against the possibility of blamelessly stumbling into a 'moral blind alley' where one would be blameworthy for whatever one is capable of doing.

G. A. Cohen was one of the most gifted, influential, and progressive voices in contemporary political philosophy. At the time of his death in 2009, he had plans to bring together a number of his most significant papers. This is the first of three volumes to realize those plans. Drawing on three decades of work, it contains previously uncollected articles that have shaped many of the central debates in political philosophy, as well as papers published here for the first time. In these pieces, Cohen asks what egalitarians have most reason to equalize, he considers the relationship between freedom and property, and he reflects upon ideal theory and political practice.Included here are classic essays such as "Equality of What?" and "Capitalism, Freedom, and the Proletariat," along with more recent contributions such as "Fairness and Legitimacy in Justice," "Freedom and Money," and the previously unpublished "How to Do Political Philosophy." On ample display throughout are the clarity, rigor, conviction, and wit for which Cohen was renowned. Together, these essays demonstrate how his work provides a powerful account of liberty and equality to the left of Ronald Dworkin, John Rawls, Amartya Sen, and Isaiah Berlin.

I presented an earlier version of this paper to the Law and Philosophy Discussion Group in Los Angeles, whose members I would like to thank for their comments. In addition, I would also like to thank the following people for reading and providing written or verbal commentary on earlier drafts: Robert Mams, Rogers Albritton, G. A. Cohen, David Copp, Matthew Hanser, Craig Ihara, Brian Lee, Marc Lange, Derk Pereboom, Carol Voeller, and the Editors of Philosophy & Public Affairs. I owe special thanks to Timothy Hall and Seana Shiffnn for their insightful and helpful comments

Cohen endorses the coercive taxation of the talented at a progressive rate for the sake of realizing equality. By contrast, he denies that it is legitimate for the state to engage in the 'Stalinist forcing' of people into one or another line of work in order to bring about a more egalitarian society. He rejects such occupational conscription on grounds of the invasiveness of the gathering and acting upon information regarding people's preferences for different types of work that would be required to implement such a policy. More precisely, Cohen maintains that the presence versus the absence of such intrusion explains why such Stalinist forcing of the talented is unacceptable whereas the progressive taxation of their income is legitimate. I argue that Cohen's appeal to invasiveness does not adequately capture the moral repugnance of the state's conscripting people into work at a given occupation. I propose that a right to self-ownership, and that which explains such a right, provides a better explanation than Cohen's of why Stalinist forcing is objectionable, whereas progressive taxation is not. 1

In The Right to Threaten and the Right to Punish, Warren Quinn justifies punishment on the ground that it can be derived from the rights of persons to protect themselves against crime. Quinn, however, denies that a right of self-protection justifies the punishment of an aggressor solely on the ground that such punishment deters others from harming the victim of that aggression or others. He believes that punishment so justified would constitute a morally objectionable instance of using the punished individual as a means. Contrary to Quinn, I argue that (1) an individual can, on the very ground of a right to self-protection that Quinn ultimately relies upon to justify punishment, justify the punishment of an individual as a means of deterring others from committing crimes; and that (2) an individual or individuals (including state officials) can, on the ground of vindicating the right of protection that others possess, justify the punishment of an individual as a means of deterring others from committing crimes.

'Moral luck' refers to the phenomenon whereby one's degree of blameworthiness for what one has done varies on account of factors beyond one's control. Applying concepts of Dworkin's from the domain of distributive justice, I draw a distinction between 'option moral luck,' which is that to which one has exposed oneself as the result of one's voluntary choices, and 'brute moral luck,' which is that which is unchosen and unavoidable. I argue that option moral luck is not ruled out on grounds of unfairness. I also offer a non-fairness-based rejection of brute moral luck and defense of option moral luck.
