On parity views of mere addition if someone is added to the world at a range of well-being levels – or ‘neutral range’ – leaving existing people unaffected, addition is on a par with the initial situation. Two distinct parity views – ‘rough equality’ and fittingattitudes views – defend the ‘intuition of neutrality’. The first can be interpreted or adjusted so that it can rebut John Broome’s objection that the neutral range is wide. The two views respond in distinct ways (...) to two of Broome’s other objections. Both views can, nonetheless, be plausibly defended against these objections. (shrink)

The capability approach developed by Nobel Laureate Amartya Sen has become an important new paradigm in thinking about development. However, despite its theoretical and philosophical attractiveness, it has been less easy to measure or to translate into policy. This volume addresses these issues in the context of poverty and justice. Part I offers a set of conceptual essays that debate the strength of the often misunderstood individual focus of the capability approach. Part II investigates the techniques by which we can (...) measure and compare capabilities, and how we can integrate them into poverty comparisons and policy advice. Finally, Part III looks at how we can apply the capability approach to different regions and contexts. Written by a team of international scholars, The Capability Approach is a valuable resource for researchers and graduate students concerned with the debate over the value of the capability approach and its potential applications.

Axiomatic utility theory plays a foundational role in some accounts of normative principles. In this context, it is sometimes argued that transitivity of “better than” is a logical truth. Larry Temkin and Stuart Rachels use various examples to argue that “better than” is non–transitive, and that transitivity is not a logical truth. These examples typically involve some sort of “discontinuity.” In his discussion of one of these examples, John Broome suggests that we should reject the claim which involves “discontinuity.” We (...) can, I suggest, make sense of the examples which Temkin uses while sacrificing neither transitivity nor “discontinuity.” This response to Temkin's examples involves developing and modifying James Griffin's account of “discontinuity.” If the account of “discontinuity” seems implausible, that is because of a failure to allow for vagueness. A similar argument can be made in the context of the well-known “repugnant conclusion.” Footnotes1 This paper emerged from a discussion in one of John Broome's seminars. I am very grateful to John Broome, Erik Carlson, James Griffin, Wlodek Rabinowicz, Stuart Rachels, and Larry Temkin for allowing me to read various forthcoming manuscripts which are mentioned in the paper. I am also extremely grateful to Gustaf Arrhenius, Walter Bossert, Luc Bovens, John Broome, Richard Cookson, Robin Cubitt, James Griffin, Graham Loomes, Ben McQuillin, Shepley Orr, Wlodek Rabinowicz, Stuart Rachels, Bob Sugden, and two anonymous referees for comments on earlier versions.

Derek Parfit’s mere addition paradox has generated a large literature. This paper articulates one response to this paradox - which Parfit hirnself suggested - in terms of a formal account of the relation of parity. I term this response the ‘parity view’. It is consistent with transitivity of ‘at least as good as’, but implies incompleteness of this relation. The parity view is compatible with critical-band utilitarianism if this is adjusted to allow for vagueness. John Broome argues against accounts which (...) involve incompleteness. He thinks they are based on an intuition of ‘neutrality’, which is most naturally understood in terms of equality. There is no rationale, on Broome’s view, for seeing it as ‘incommensurateness’ which leads to incompleteness. Parity provides one. Broome’s worries that ‘incommensurateness’ makes neutrality implausibly ‘greedy’, and that ‘incommensurateness’ and vagueness are incompatible do not constitute a knock-down case against the parity view. Similar worries arise for his preferred vagueness view. (shrink)

In comparing Sen's work with Mill's, Sugden criticizes Sen's capability approach because it may be applied in such a way that society or theorists judge what is best for people and potentially restrict liberty on that basis. Sugden cites Nussbaum's work as evidence in making his case. Sugden's critique of Sen's approach succeeds on a narrow reading of it. On that reading Sen is also critical of it because it does not leave enough room for liberty. On a broad reading, (...) the critique has less force. Nussbaum's approach follows Mill in allowing people freedom to act on whatever desires they have if this does not harm others. This neutralizes the central element of Sugden's critique as it applies to her approach to some degree. Both Sen and Nussbaum nonetheless recognize the danger of illiberal restrictions in application which motivates Sugden's critique. (shrink)

Amartya Sen has recently suggested that certain issues which arise in the application of the capability approach can be seen in terms of social choice. This article explores certain connections and tensions between Kenneth Arrow's celebrated discussion of social choice and the capability approach while focusing on one central link: pluralism. Given the variety of values people hold, substantive issues which arise in the application of the capability approach can be seen as social choice problems. Seeing them in this way (...) helps to explain some of Sen's suggestions about applying the approach in the light of an analogue of Arrow's theorem. However, it also poses a potential problem because of the focus on preferences in social choice theory, given that the capability approach is motivated in part by problems which `adaptive preferences' raise for `utility'-based views. In this article, it is argued that Sen's writings about public reasoning allow him to address this problem to some degree. The reading underlying this argument clarifies issues about the relationship between the individual and society in his approach. It also illuminates the extent of Sen's debt to John Rawls's writings on `public reason', while clarifying some points on which Sen and Rawls diverge. Key Words: social choice • capability • welfare • democracy. (shrink)

While there is much common ground between the writings of Amartya Sen and John Stuart Mill – particularly in their advocacy of freedom and gender equality – one is a critic, while the other is an advocate, of utilitarianism. In spite of this contrast, there are strong echoes of Sen's capability approach in Mill's writings. Inasmuch as Mill sees the capability to be happy as important he holds a form of capability approach. He also thinks of happiness as constituted by (...) the exercise of certain capabilities (including the higher faculties). Furthermore, Mill addresses the possibility that people can adapt to limited opportunity, which is central to Sen's critique of some ‘utility’-based views. By contrasting contentment and happiness Mill suggests one way in which a utilitarian might address cases of adaptation. His discussions of capabilities and of adaptation are consistent with his utilitarianism. (Published Online February 16 2006). (shrink)

James Griffin (1986, 1997, 2000) and Ruth Chang (1997) have argued that alternatives (and values) can be comparable when it is neither true that one is better than the other, nor true that they are exactly equal in value. The relation which holds between them has gone under various names: the alternatives are (Griffin) or (Chang). In this paper, I give a formal analysis of this relation. This analysis allows us to distinguish between two slightly different notions of . It (...) is argued that the distinction between these notions is important for discussions of rationality, as is the distinction between or and incomparability. (shrink)

The concept of well-being is central to the subject matter of moral philosophy as well as economics. According to some moral theorists morality is about the maximization of social well-being. According to others, notably John Rawls we ought to give particular priority to the worst off members in society. Both these and other moral positions, whatever the priority they attach to different members of society in arriving at moral judgements, require an account of well-being or advantage. The concern with well-being (...) is thus of foundational importance in moral philosophy, even if well-being is not thought of as all that matters. Furthermore, those who want to distinguish ‘morality’ from ‘self-interest’ must furnish us with an account of human interests, so that we can distinguish the moral realm from that of self-interest or prudence. The concerns of moral philosophers, here, clearly overlap with those of economists. Economists are much concerned with questions of how well people are doing, with their ‘standard of living’ or ‘quality of life’. However, there are very different ways of thinking about each of these ideas. Indeed, we need to discriminate between different views of the quality of life and to decide which is the most appropriate for the purposes of moral theory and the normative parts of economics.

There are several different forms of comparability involving prudential values. Comparisons of values in the abstract, of realizations of some value, and of options which realize values, are distinct, and related, though not mutually exclusive. Furthermore, if rough equality is thought of as an evaluative relation in terms of which comparisons can be made, it does not imply incomparability. If it involves epistemic vagueness, this does not imply incomparability, since our not knowing which relation holds does not imply that no (...) relation holds. Finally, if it is true to some degree that some relation holds, there may be some fuzzy ordering. Given that we may not be able coherently to talk about degrees of truth, I propose an open-ended comparability condition, which takes account of rough equality, epistemic vagueness and fuzziness.

Frances Howard-Snyder argues that objective consequentialism should be rejected because it violates the principle of ‘ought’ implies ‘can’ in asking us to do what we cannot. In this comment I suggest that Howard-Snyder does not take sufficiently seriously the chief defence of objective consequentialism, which reformulates it so that it applies only to actions we can perform. Nonetheless, I argue that there are arguments relating to ‘ought’ implies ‘can’ which discredit objective consequentialism even if it is thus reformulated. These arguments (...) also cause problems for a reformulated version of subjective consequentialism. (shrink)

Philosophical accounts of human well-being face a number of significant challenges. In this paper, I shall be primarily concerned with one of these. It relates to the possibility, noted by Martha Nussbaum and Amartya Sen amongst others, that people’s desires and attitudes are malleable and can ‘adapt’ in various ways to the straitened circumstances in which they live. If attitudes or desires adapt in this way it can be argued that the relevant desires or attitudes fail to provide a reliable (...) basis for evaluating well-being. This is, what I shall call the ‘adaptation problem’. Nussbaum and Sen have—in different ways used this argument to motivate their versions of the ‘capability approach’. However, questions remain about the implications of adaptation for philosophical accounts of well-being. (shrink)

Amartya Sen's recent works on identity have emerged at the same time as a much wider and growing literature on the topic across the disciplines of politics, philosophy, and economics. This article outlines some of Sen's claims and attempts a partial elucidation of their relationship to some strands in the relevant literatures on identity, community, and justice. It thereby frames Sen's works in such a way as to facilitate comparisons with other views on identity and multiculturalism, community, justice, and recognition (...) which feature in this volume and the relevant literatures. Framing Sen's work in this way also helps to clarify Sen's position in relation to those of Bhikhu Parekh and certain communitarian thinkers. (shrink)

The vagueness view holds that when evaluative comparisons are hard, there is indeterminacy about which comparative relation holds. It is sceptical about whether there are any incommensurate items (in some domain). The sceptical element of John Broome’s version of this view rests on a controversial principle. Robert Sugden advances a similar view which does not depend on this principle. Sugden’s argument fails as a vagueness view because it assumes rather than shows that there are no incommensurate items (in some domain). (...) Nonetheless, I argue that an interpretation of his argument constitutes a defensible vagueness view which is supported by intuition about examples. On this interpretation Sugden’s view can be mapped onto Broome’s application of a supervaluationist view of vagueness. It is also (on this reading) a close relative of James Griffin’s ‘rough equality’ view when this is interpreted in terms of vagueness. On an alternative interpretation Sugden’s view is not sceptical about incommensurateness. On this interpretation he does not defend a vagueness view and is ‘sceptical’ about the contribution of the philosophical literature to our understanding of rational choice. (shrink)

This landmark handbook collects in a single volume the current state of cutting-edge research on the capability approach. It includes a comprehensive introduction to the approach as well as new research from leading scholars in this increasingly influential multi-disciplinary field, including the pioneers of capability research, Martha C. Nussbaum and Amartya Sen. Incorporating both approachable introductory chapters and more in-depth analysis relating to the central philosophical, conceptual and theoretical issues of capability research, this handbook also includes analytical and measurement tools, (...) as well as policy approaches which have emerged in the recent literature. The handbook will be an invaluable resource for students approaching the capability approach for the first time as well as for researchers engaged in advanced research in a wide range of disciplines, including development studies, economics, gender studies, political science and political philosophy.

One response to Derek Parfit's invokes the relation of . Since parity is a form of in John Broome's terms, three doubts which Broome raises about accounts involving incommensurateness in Weighing Lives pose a challenge for this response. I discuss two of these. They emerge from a discussion of various intuitions about . I argue that an account based on parity may be no less consistent with Broome's intuitions than is his own vagueness view.

In criticizing communitarian views of justice, Amartya Sen argues that identity is not merely a matter of discovery but an object of reasoned choice subject to constraints. Distinguishing three notions of identity – self-perception, perceived identity and social affiliation – I claim that the relevant constraints implied by this argument are minimal. Some of Sen's arguments about perceived identity and social context do not establish any further constraints. Sen also argues that a model of multiculturalism and some forms of education (...) can restrict, or fail to promote, reasoned and informed identity choice. This argument is better understood in the light of Sen's work on capability and justice, notably his concern with ways in which underdogs can adapt and his emphasis on public reasoning. It highlights limitations on information and opportunities for reasoning. I suggest that these lead to genuine constraints on identity choice. The paper focuses on Sen's work, though its claims are also relevant to George Akerlof and Rachel Kranton's analysis of identity. (shrink)

Items are incommensurate if it is false that one is better than the other or that they are exactly as or equally good. John Broome claims that there are no incommensurate items (in some domain), but that there is vagueness. Wlodek Rabinowicz casts doubt on this claim because he rejects a principle which Broome adopts in advancing it. I argue that Robert Sugden's discussion can be interpreted as advancing a version of this claim which does not depend on the relevant (...) principle and which can respond to certain objections.

Economists have often attempted precise measurement of phenomena which involve vague predicates. Difficulties emerge in such attempts if vagueness is not explicitly acknowledged at the methodological level. In this paper, various accounts of vague concepts are used to think about the economics of poverty measurement. Approaches to dealing with vagueness in this context tend to involve 'epistemic' and 'fuzzy set theoretic' approaches. Indeed, only the fuzzy set theoretic literature takes on vagueness explicitly. It is argued that both these approaches encounter (...) significant difficulties, and that fuzzy set theoretic measures are hard to interpret intuitively. A 'supervaluationist' approach to the vagueness of poverty is developed. It is argued that this approach has much to recommend it and that some fuzzy measures can be interpreted intuitively as measures of vulnerability on this account. (shrink)

This paper uses a formal analysis of the relation of ‘parity’ to make sense of a well-known solution to Parfit’s ‘mere addition paradox’. This solution is sometimes dismissed as a recourse to ‘incomparability’. In this analysis, however, the solution is consistent with comparability, as well as transitivity of ‘better than’. The analysis is related to Blackorby, Bossert and Donaldson’s ‘incomplete critical-level generalised utilitarianism’ (ICLGU). ICLGU is inspired by Parfit’s work and can be related to the analysis of parity, though the (...) distinctive ‘mark’ of parity suggests that the boundaries of a set of critical levels is not exact. One has to allow for vagueness to make an account based on parity plausible. These accounts are then contrasted with Broome’s view which also involves vagueness. (shrink)
