The egalitarian values of equality and priority are standardly given maximal scope in that they are applied to the overall condition of peoples' lives and to temporally complete lifetimes. They are also standardly restricted to interpersonal choices. This paper argues that egalitarian values can also reasonably be applied to particular dimensions of lives, to people at particular times, and to choices made about one person's life. It contends that these special applications of egalitarianism are easier to defend in the case (...) of priority than in the case of equality. (shrink)

Philosophical discussions of prioritarianism, the view that we ought to give priority to those who are worse off, have hitherto been almost exclusively focused on cases involving a fixed population. The aim of this paper is to extend the discussion of prioritarianism to encompass also variable populations. I argue that prioritarianism, in its simplest formulation, is not tenable in this area. However, I also propose several revised formulations that, so I argue, show more promise.

:Both egalitarianism and prioritarianism give value to equality. Prioritarianism has an additively separable value function whereas egalitarianism does not. I show that in some cases prioritarianism and egalitarianism necessarily have different implications: I describe two alternatives G and H such that egalitarianism necessarily implies G is better than H whereas prioritarianism necessarily implies G and H are equally good. I also raise a doubt about the intelligibility of prioritarianism.

This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

The Interpersonal Addition Theorem, due to John Broome, states that, given certain seemingly innocuous assumptions, the overall utility of an uncertain prospect can be represented as the sum of its individual utilities. Given ‘Bernoulli's hypothesis’ according to which individual utility coincides with individual welfare, this result appears to be incompatible with the Priority View. On that view, due to Derek Parfit, the benefits to the worse off should count for more, in the overall evaluation, than the comparable benefits to the (...) better off. Pace Broome, the paper argues that prioritarians should meet this challenge not by denying Bernoulli's hypothesis, but by rejecting one of the basic assumptions behind the addition theorem: that a prospect is better overall if it is better for everyone. This conclusion follows if one interprets the priority weights that are imposed by prioritarians as relevant only to moral, but not to prudential, evaluations of prospects. (shrink)

Over the years, egalitarian philosophers have made some challenging claims about the nature of egalitarianism. They have argued that egalitarian reasoning should make us reject the Pareto principle; that the Rawlsian leximin principle is not an egalitarian idea; that the Pigou–Dalton principle needs modification; that the intersection approach faces deep problems; that the numbers should not count within an egalitarian framework, and that egalitarianism should make us reject the property of transitivity in normative reasoning. In this paper, taking the recent (...) philosophical debate on equality versus priority as the starting point, I review these claims from the point of view of an economist. (shrink)

This paper takes a simple, informal suggestion by Broome and another more explicit suggestion by Kamm for how to deal with asymmetric claims and shows how they can be interpreted to be consistent with two different social welfare functions: Sum-of-square-roots of individual utilities, and product of utilities. These functions are then used to analyze more complicated situations but I show that the first yields more intuitive results, and a better compromise of efficiency and justice, than the other.

Just as there are rational requirements on thought, there are rational requirements on action. This book defends a conception of ethics, and a related conception of human nature, according to which altruism is included among the basic rational requirements on desire and action. Altruism itself depends on the recognition of the reality of other persons, and on the equivalent capacity to regard oneself as merely one individual among many.

A natural formalization of the priority view is presented which results from adding expected utility theory to the main ideas of the priority view. The result is ex post prioritarianism. But ex post prioritarianism entails that in a world containing just one person, it is sometimes better for that person to do what is strictly worse for herself. This claim may appear to be implausible. But the deepest objection to ex post prioritarianism has to do with meaning: ex post prioritarianism (...) is not a genuine alternative to utilitarianism in the first place. By contrast, ex ante prioritarianism is defensible. But its motivation is very different from the usual rationales offered for the priority view. Given their hostility to egalitarianism, most supporters of the priority view have not provided reasons to reject utilitarianism. (shrink)

The priority view has become very popular in moral philosophy, but there is a serious question about how it should be formalized. The most natural formalization leads to ex post prioritarianism, which results from adding expected utility theory to the main ideas of the priority view. But ex post prioritarianism entails a claim which is too implausible for it to be a serious competitor to utilitarianism. In fact, ex post prioritarianism was probably never a genuine alternative to utilitarianism in the (...) first place. By contrast, ex ante prioritarianism is defensible. But its motivation is very different from the usual rationales offered for the priority view. Given the untenability of ex post prioritarianism, it is more natural for most friends of the priority view to revert to utilitarianism. (shrink)

Egalitarians think that equality in the distribution of goods somehow matters. But what exactly is egalitarianism? This article argues for a characterization based on novel principles essentially involving risk. The characterization is then used to resolve disputed questions about egalitarianism. These include: the way egalitarianism is concerned with patterns, in particular its relationship to strong separability; the relationship between egalitarianism and other distributive views, such as concerns with fairness and with giving priority to the worse off; and the relationship between (...) egalitarianism and evaluative measurement. But egalitarianism is subject to a particularly severe form of the levelling-down objection, and is claimed to be false. (shrink)

It is common to define egalitarianism in terms of an inequality ordering, which is supposed to have some weight in overall evaluations of outcomes. Egalitarianism, thus defined, implies that levelling down makes the outcome better in respect of reducing inequality; however, the levelling down objection claims there can be nothing good about levelling down. The priority view, on the other hand, does not have this implication. This paper challenges the common view. The standard definition of egalitarianism implicitly assumes a context. (...) Once this context is made clear, it is easily seen that egalitarianism could be defined alternatively in terms of valuing a benefit to a person inversely to how well off he is relative to others. The levelling down objection does not follow from this definition. Moreover, the common definition does not separate egalitarian orderings from prioritarian ones. It is useful to do this by requiring that on egalitarianism, additively separable orderings should be excluded. But this requirement is stated as a condition on the alternative definition of egalitarianism, from which the levelling down objection does not follow. (shrink)

Hurley here revives a classical idea about rationality in a modern framework, by developing analogies between the structure of personality and the structure of society in the context of contemporary work in philosophy of mind, ethics, decision theory and social choice theory. The book examines the rationality of decisions and actions, and illustrates the continuity of philosophy of mind on the one hand, and ethics and jurisprudence on the other. A major thesis of the book is that arguments drawn from (...) the philosophy of mind may be used to undermine widely-held subjectivist positions in ethics and politico-economic theory. The work is inspired by the philosophies of Wittgenstein and Davidson, but goes on to connect their arguments about interpretation with formal work in decision theory and social choice theory, and with the theory of adjudication.

:This paper questions the distinction between egalitarianism and prioritarianism, arguing that it is important to separate the reasons for particular social preferences from the contents of these preferences, that it is possible to like equality and separability simultaneously, and that some egalitarians and prioritarians may therefore share the same social preferences. The case of risky prospects, for which Broome has proposed an interesting example meant to show that egalitarians and prioritarians cannot share the same preferences, is scrutinized. The levelling down (...) objection is also examined. (shrink)

Derek Parfit presents the third volume of On What Matters, his landmark work of moral philosophy. Parfit develops further his influential treatment of reasons, normativity, the meaning of moral discourse, and the status of morality. He engages with his critics, and shows the way to resolution of their differences.

This study uses techniques from economics to illuminate fundamental questions in ethics, particularly in the foundations of utilitarianism. Topics considered include the nature of teleological ethics, the foundations of decision theory, the value of equality and the moral significance of a person's continuing identity through time.

Based on the 1972 Radcliffe Lectures, this book presents a systematic treatment of the conceptual framework as well as the practical problems of measurement of inequality.

This book provides an introduction to measurement theory for non-specialists and puts measurement in the social and behavioural sciences on a firm mathematical foundation. Results are applied to such topics as measurement of utility, psychophysical scaling and decision-making about pollution, energy, transportation and health. The results and questions presented should be of interest to both students and practising mathematicians since the author sets forth an area of mathematics unfamiliar to most mathematicians, but which has many potentially significant applications.

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

I begin, in section 1, with a presentation of the Interpersonal Addition Theorem. The theorem, due to John Broome (1991), is a re-formulation of the classical result by Harsanyi (1955). It implies that, given some seemingly mild assumptions, the overall utility of an uncertain prospect can be seen as the sum of its individual utilities. In sections 1 and 2, I discuss the theorem's connection with utilitarianism and in particular consider its implications for the Priority View, according to which benefits (...) to the worse off count for more, in terms of overall utility, than comparable benefits to the better off (cf. Parfit 1995 [1991]). Broome (1991) and Klint Jensen (1996) have argued that, in view of the Interpersonal Addition Theorem, the Priority View should be rejected for measurement-theoretical reasons. Therefore, it cannot be seen as a plausible competitor to utilitarianism (cf. section 1). I will suggest, however, that a proponent of the Priority View would be well-advised, on independent grounds, to reject one of the basic assumptions on which the Addition Theorem is based. I have in mind the so-called Principle of Personal Good for uncertain prospects (cf. sections 4 and 5). If the theorem is disarmed in this way, then, as a side benefit, the Priority View will avoid the afore-mentioned problems with measurement. (shrink)

One of the central debates within contemporary Anglo-American political philosophy concerns how to formulate an egalitarian theory of distributive justice which gives coherent expression to egalitarian convictions and withstands the most powerful anti-egalitarian objections. This book brings together many of the key contributions to that debate by some of the world’s leading political philosophers: Richard Arneson, G.A. Cohen, Ronald Dworkin, Thomas Nagel, Derek Parfit, John Rawls, T.M. Scanlon, and Larry Temkin.

This paper takes its departure from the Interpersonal Addition Theorem. The theorem, by John Broome, is a re-formulation of the classical result by Harsanyi. It implies that, given some seemingly mild assumptions, the overall utility of an uncertain prospect can be seen as the sum of its individual utilities. In sections 1 and 2, I discuss the theorem’s connection with utilitarianism and in particular the extent to which this theorem still leaves room for the Priority View. According to the latter, (...) the utilitarian approach needs to be modified: Benefits to the worse off should count for more, overall, than the comparable benefits to the better off.Broome and Jensen have argued that the Priority View cannot be seen as a plausible competitor to utilitarianism: Given the addition theorem, prioritarianism should be rejected for measurement-theoretical reasons. I suggest that this difficulty is spurious: The proponents of the Priority View would be well advised, on independent grounds, to reject one of the basic assumptions on which the addition theorem is based, the so-called Principle of Personal Good for uncertain prospects.According to the Principle of Personal Good, one prospect is better than another if it is better for everyone or at least better for some and worse for none. That the Priority View, as I read it, rejects this welfarist intuition may be surprising. Isn’t welfarism a common ground for prioritarians and utilitarians? Still, as I argue, this welfarist common ground is better captured by a restricted Principle of Personal Good that is valid for *outcomes*, but not necessarily for uncertain prospects. We obtain this surprising result if we take the priority weights imposed by prioritarians to be relevant only to *moral*, but not to *prudential*, evaluations of prospects. This makes it possible for a prospect to be morally better even though it is worse for everyone concerned. The proposed interpretation of the Priority View thus drives a sharp wedge between prudence and morality. (shrink)

Temkin presents a new way of thinking about equality and inequality that challenges the assumptions of philosophers, welfare economists, and others, and has significant implications on both a practical and theoretical level.
