Much contemporary egalitarian theorizing is broadly divided between luck egalitarians, such as G. A. Cohen, Richard Arneson, and John Roemer, and relational egalitarians, such as John Rawls, Samuel Scheffler, Josh Cohen, and me. The two camps disagree about how to conceive of equality: as an equal distribution of non-relational goods among individuals, or as a kind of social relation between persons - an equality of authority, status, or standing.This disagreement generates a second, about when unequal distributions of non-relational goods are (...) unjust. Luck egalitarians claim that inequality is unjust when it is accidental: when it is caused by morally arbitrary factors such as circumstances of birth. Relational egalitarians claim that inequality is unjust when it disadvantages people: when it reflects, embodies, or causes inequality of authority, status, or standing. (shrink)

Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collective obligation and (...) ability in the proposed way is that a group can be blameworthy for failing to realize its obligation even when no member of the group is blameworthy for failing to realize her obligation.

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she releases ideal theorists (...) from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

This paper has three aims. First, it argues that the present use of ‘ideal theory’ is unhelpful, and that an earlier and apparently more natural use focusing on perfection would be preferable. Second, it has tried to show that revision of the use of the term would better expose two distinctive normative issues, and illustrated that claim by showing how some contributors to debates about ideal theory have gone wrong partly through not distinguishing them. Third, in exposing those two distinct (...) normative issues, it has revealed a particular way in which ideal theory even under the more specific, revisionary definition will often be central to working out what to do in non-ideal circumstances. By clarifying the terms on which debates over ideal and non-ideal theory should take place, and highlighting the particular problems each deals with, it tries to clear the ground for turning to the actual problem, which is what to do in our non-ideal and often tragic circumstances.

This article sets out some of the key features of a realist critique of liberal moralism, identifying descriptive inadequacy and normative irrelevance as the two fundamental lines of criticism. It then sketches an outline of a political theory of modus vivendi as an alternative, realist approach to political theory. On this account a modus vivendi should be understood as any political settlement that involves the preservation of peace and security and is generally acceptable to those who are party to it. (...) In conclusion, some problems with this conception of modus vivendi and with a realist political theory more generally are discussed. In particular, the question is raised of whether a realist political theory should be understood as an alternative to liberal moralism or only a better way of doing basically the same kind of thing.

At the end of a thoughtful article on the future of nuclear war, Wiesner and York concluded that: "Both sides in the arms race are... confronted by the dilemma of steadily increasing military power and steadily decreasing national security. It is our considered professional judgment that this dilemma has no technical solution. If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.".

To be justifiable, the demands of a conception of human rights and global justice must be such that (a) they focus on the protection of important human interests, and (b) their fulfilment is feasible. I discuss the feasibility condition. I present a general account of the relation between moral desirability, feasibility and obligation within a conception of justice. I analyse feasibility, a complex idea including different types, domains and degrees. It is possible to respond in various ways if the fulfilment (...) of basic socioeconomic human rights against severe poverty seems at first to be infeasible. (shrink)

What should our theorizing about social justice aim at? Many political philosophers think that a crucial goal is to identify a perfectly just society. Amartya Sen disagrees. In The Idea of Justice, he argues that the proper goal of an inquiry about justice is to undertake comparative assessments of feasible social scenarios in order to identify reforms that involve justice-enhancement, or injustice-reduction, even if the results fall short of perfect justice. Sen calls this the “comparative approach” to the theory of (...) justice. He urges its adoption on the basis of a sustained critique of the former approach, which he calls “transcendental.” In this paper I pursue two tasks, one critical and the other constructive. First, I argue that Sen’s account of the contrast between the transcendental and the comparative approaches is not convincing, and second, I suggest what I take to be a broader and more plausible account of comparative assessments of justice. The core claim is that political philosophers should not shy away from the pursuit of ambitious theories of justice (including, for example, ideal theories of perfect justice), although they should engage in careful consideration of issues of political feasibility bearing on their practical implementation.

There is a widespread belief that, conceptually, justice cannot require what we cannot achieve. This belief is sometimes used by defenders of so-called ‘non-ideal theories of justice’ to criticise so-called ‘ideal theories of justice’. I refer to this claim as ‘the feasibility constraint on the concept of justice’ and argue against it. I point to its various implausible implications and contend that a willingness to apply the label ‘unjust’ to some regrettable situations that we cannot fix is going to enhance (...) the action-guiding potential of a conception of justice, by providing an aspirational ideal. This is possible on the condition that, at all times, we cannot specify with certainty the limits of what is feasible for us collectively. The rejection of the feasibility constraint entails that there can be injustice without perpetrators; this is a theoretical price worth paying. (shrink)

This book is vigorous in its arguments, displays an impressive historical sweep, and on several occasions gets in the perfect skewering criticism.

In recent decades, a ‘realist’ alternative to ideal theories of politics has slowly taken shape. Bringing together philosophers, political theorists, and political scientists, this countermovement seeks to reframe inquiry into politics and political norms. Among the hallmarks of this endeavor are a moral psychology that includes the passions and emotions; a robust conception of political possibility and rejection of utopian thinking; the belief that political conflict — of values as well as interests — is both fundamental and ineradicable; a focus (...) on institutions as the arenas within which conflict is mediated and contained; and a conception of politics as a sphere of activity that is distinct, autonomous, and subject to norms that cannot be derived from individual morality. For political realists, a ‘well-ordered society’ is rarely attainable; a modus vivendi without agreement on first principles is often the only practical possibility. Not only will ‘full compliance’ never be achieved, but also it is an assumption that yields misleading accounts of political norms. While realists offer a number of compelling criticisms of ideal theory, there are some lacunae in their stance. It is not yet clear whether realism constitutes a coherent affirmative alternative to idealism. Nor have realists clarified the extent of conflict that is consistent with political order as such. And because both sides accept ‘ought implies can’ as a constraint on the validity of political norms, much of the debate between realists and idealists revolves around deep empirical disagreements that are yet to be clarified.
