In his Tanner Lecture of 1979 called ‘Equality of What?’ Amartya Sen asked what metric egalitarians should use to establish the extent to which their ideal is realized in a given society. What aspect of a person’s condition should count in a fundamental way for egalitarians, and not merely as cause of or evidence of or proxy for what they regard as fundamental?

This book addresses issues of defining and measuring the quality of life. Leading philosophers and economists examine recent developments in the philosophical definition of well-being and link them to practical issues such as the delivery of health care and the assessment of women's quality of life. The volume reflects the growing need for interdisciplinary work as economists become more aware of fundamental philosophical questions and philosophers of the importance of linking theoretical enquiries to an understanding of complex practical problems.

Natural Justice is a bold attempt to lay the foundations for a genuine science of morals using the theory of games. Since human morality is no less a product of evolution than any other human characteristic, the book takes the view that we need to explore its origins in the food-sharing social contracts of our prehuman ancestors. It is argued that the deep structure of our current fairness norms continues to reflect the logic of these primeval social contracts, but the (...) particular fairness norm a society operates is largely a product of cultural evolution. In pursuing this point, the book proposes a naturalistic reinterpretation of John Rawls' original position that reconciles his egalitarian theory of justice with John Harsanyi's utilitarian theory by identifying the environment appropriate to each.

I compare Mill's and Sen's accounts of the value of opportunity, focusing on a tension between two ideas they both uphold: that individual freedom is an important component of well-being, and that, because desires can be adaptive, actual desire is not always a good indicator of what will give well-being. The two writers' responses to this tension reflect different understandings of the relationship between freedom and desire. Sen links an individual's well-being to her freedom to choose what she has reason (...) to desire, and looks to a democratic political process for a collective judgement about what it is rational to desire. Mill links the individual's well-being to her freedom to act on her own desires, whatever they may be, within the constraints imposed by a fair initial distribution of resources. He sees no need for collective judgement about what is ultimately valuable in human life. I side with Mill. (Published Online February 16 2006). (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)

I am embarrassed at being placed in the dizzying company of one of the truly great thinkers in the world. The similarities between Mill's ideas and mine partly reflect, of course, his influence on my thinking. But I also discuss some difficulties in taking Mill's whole theory without modification, since there are internal tensions within it. In a paper I published in 1967, I tried to discuss how Mill's willingness to hold on to some contrary positions depended on the nature (...) of his empirical reading of the world. I draw on that diagnosis in commenting on some of the articles here. There are some serious issues of misinterpretation in one of the articles, which I try to clarify. I also comment on Arrow's interpretation of what is involved in the idea of autonomy and on his own way of assessing freedom, and acknowledge the seriousness of the questions he raises about the value of freedom in normative political philosophy.

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)

Sabina Alkire shows how Nobel Prize-winning economist Amartya Sen's capability approach can be coherently---and practically---put to work in poverty reduction activities so that the voices and values of the poor matter. This provides economists, philosophers, theologians, and development practitioners with a way forward that addresses both theoretical and practical challenges.

Philosophers perennially debate the nature of the good for humans. Is it subjective or objective? That is to say, do the things that are intrinsically good for an agent, good for their own sakes and apart from further consequences, acquire this status only in virtue of how she happens to regard them? Or are there things that are good in themselves for an individual independently of her desires and attitudes toward them? The issue sounds recondite, but has been thought to (...) be pregnant with implications for politics as it ought to be. Plato vigorously insists that knowledge of the good is precious and the person who has it is uniquely fit to rule: "In the world of knowledge, the last thing to be perceived and only with great difficulty is the essential Form of Goodness. Once it is perceived, the conclusion must follow that, for all things, this is the cause of whatever is right and good; in the visible world it gives birth to the light and to the lord of light, while it is itself sovereign in the intelligible world and the parent of wisdom and truth. Without having had a vision of this Form no one can act with wisdom, either in his own life or in matters of state.". (shrink)

If some external enforcement agency compels us to honor deals reached in the original position, then Harsanyi has shown that the outcome will be utilitarian. Under the same hypotheses, Rawls claims that the outcome will be egalitarian. This chapter confirms that Harsanyi is correct. It goes on to use the concept of an empathy equilibrium to predict the standard of interpersonal comparison needed to operate a utilitarian norm that will evolve in the medium run.
