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.

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 essay examines several possible rationales for the egalitarian judgment that justice requires better-off individuals to help those who are worse off even in the absence of social interaction. These rationales include equality (everyone should enjoy the same level of benefits), moral meritocracy (each should get benefits according to her responsibility or deservingness), the threshold of sufficiency (each should be assured a minimally decent quality of life), prioritarianism (a function of benefits to individuals should be maximized that gives priority to (...) the worse off), and mixed views. A case is made for adopting either prioritarianism or a mixed view that gives priority both to the worse off and to the more responsible and deserving. (shrink)

Since it appeared in 1971, John Rawls's A Theory of Justice has become a classic. The author has now revised the original edition to clear up a number of difficulties he and others have found in the original book. Rawls aims to express an essential part of the common core of the democratic tradition--justice as fairness--and to provide an alternative to utilitarianism, which had dominated the Anglo-Saxon tradition of political thought since the nineteenth century. Rawls substitutes the ideal of the (...) social contract as a more satisfactory account of the basic rights and liberties of citizens as free and equal persons. "Each person," writes Rawls, "possesses an inviolability founded on justice that even the welfare of society as a whole cannot override." Advancing the ideas of Rousseau, Kant, Emerson, and Lincoln, Rawls's theory is as powerful today as it was when first published. (shrink)

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

This is a paperback edition of a major contribution to the field, first published in hard covers in 1977. The book outlines a general theory of rational behaviour consisting of individual decision theory, ethics, and game theory as its main branches. Decision theory deals with a rational pursuit of individual utility; ethics with a rational pursuit of the common interests of society; and game theory with an interaction of two or more rational individuals, each pursuing his own interests in a (...) rational manner.

Utilitarianism has a curious history. Its most celebrated founders—Jeremy Bentham and John Stuart Mill—were radical progressives, straddling the worlds of academic philosophy, political science, economic theory and practical affairs. They made innumerable recommendations for legal, social, political and economic reform, often (especially in Bentham’s case) described in fine detail. Some of these recommendations were followed, sooner or later, and many of their radical ideas have become close to articles of faith of western liberalism. Furthermore many of these recommendations were made (...) expressly to improve the condition of the deprived, or of oppressed groups. Yet the moral theory which inspired this reforming zeal is, at least officially, utilitarianism, and when we teach this theory to our students we feel it our duty to point out the horrors that could be justified by any theory which assesses the moral quality of actions in terms of the maximization of good consequences over bad. No consequence is so bad that it cannot, in principle, be outweighed by a large aggregation of smaller goods. Hence there are circumstances in which utilitarianism can require slavery, the punishment of the innocent, and redistribution of resources from the poor to the rich, or from the disabled and the sick to the able bodied and healthy. Indeed, in the right circumstances, it can justify pretty much anything you can think of. For all their intelligence and imagination neither Bentham nor Mill seemed to recognise or discuss these catastrophic possibilities. (shrink)

What is a fair distribution of resources and other goods when individuals are partly responsible for their achievements? This book develops a theory of fairness incorporating a concern for personal responsibility, opportunities and freedom. With a critical perspective, it makes accessible the recent developments in economics and philosophy that define social justice in terms of equal opportunities. It also proposes new perspectives and original ideas. The book separates mathematical sections from the rest of the text, so that the main concepts (...) and ideas are easily accessible to non-technical readers. -/- It is often thought that responsibility is a complex notion, but this monograph proposes a simple analytical framework that makes it possible to disentangle the different concepts of fairness that deal with neutralizing inequalities for which the individuals are not held responsible, rewarding their effort, respecting their choices, or staying neutral with respect to their responsibility sphere. It dwells on paradoxes and impossibilities only as a way to highlight important ethical options and always proposes solutions and reasonable compromises among the conflicting values surrounding equality and responsibility. -/- The theory is able to incorporate disincentive problems and is illustrated in the examination of applied policy issues such as: income redistribution when individuals may be held responsible for their choices of labor supply or education; social and private insurance when individuals may be held responsible for their risky lifestyle; second chance policies; the measurement of inequality of opportunities and social mobility.

Cost–benefit analysis (CBA) is much more philosophically interesting than has in general been recognized. Since it is the only well-developed form of applied consequentialism, it is a testing-ground for consequentialism and for the counterfactual analysis that it requires. Ten classes of philosophical problems that affect the practical performance of cost–benefit analysis are investigated: topic selection, dependence on the decision perspective, dangers of super synopticism and undue centralization, prediction problems, the indeterminateness of our control over future decisions, the need to exclude (...) certain consequences for moral reasons, bias in the delimitation of consequences, incommensurability of consequences, difficulties in defending the essential requirement of transferability across contexts, and the normatively questionable but equally essential assumption of interpersonal compensability.

When is it morally acceptable to expose others to risk? Most moral philosophers have had very little to say in answer to that question, but here is a moral philosopher who puts it at the centre of his investigations.

This book addresses a range of relevant theoretical issues, including the possibility of an interpersonally comparable measure of well-being, or “utility” metric; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the possibility of integrating considerations of individual choice and responsibility into the social-welfare-function framework. This book also deals with issues of implementation, and explores how survey data and other sources of evidence might be used to calibrate (...) both a utility metric and a social welfare function, and whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, the book draws from a wide variety of literatures, including philosophical scholarship on equality, responsibility, the nature of well-being, and personal identity over time; the social choice literature within economics; applied economic literatures concerning the measurement of inequality and poverty; legal and policy-analysis scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of “happiness studies”.

The article investigates the resources of contractualist moral theory to make sense of the ethics of risk imposition. In some ways, contractualism seems well placed to explain how it can be reasonable to accept exposure to risk of harms whose direct imposition would not be acceptable. However, there are difficulties getting clear about what directness comes to here, especially given the difficulty of adequately motivating traditional views that assign ethical significance to what the agent intends as opposed to merely foreseeing. (...) The article considers two principles which might help the contractualist: the Redistribution Principle, which, while attractive, is perhaps somewhat too restrictive, and the Aim Consistency Principle, which grants ethical significance to the aims with which our actions are in principle consistent whatever our actual intentions may be. The article also considers the relative significance of ex ante and ex post perspectives from which to evaluate actions and principles. Key Words: contractualism • Doctrine of Double Effect • ethics • intention • justice • risk • T.M. Scanlon • utilitarianism. (shrink)

Should we remain neutral between our interests and those of future generations? Or are we ethically permitted or even required to depart from neutrality and engage in some measure of intergenerational discounting? This Article addresses the problem of intergenerational discounting by drawing on two different intellectual traditions: the social welfare function (“SWF”) tradition in welfare economics, and scholarship on “prioritarianism” in moral philosophy. Unlike utilitarians, prioritarians are sensitive to the distribution of well-being. They give greater weight to well-being changes affecting (...) worse-off individuals. Prioritarianism can be captured, formally, through an SWF which sums a concave transformation of individual utility, rather than simply summing unweighted utilities in utilitarian fashion. The Article considers the appropriate structure of a prioritarian SWF in intergenerational cases. The simplest case involves a fixed and finite intertemporal population. In that case, I argue, policymakers can and should maintain full neutrality between present and future generations. No discount factor should be attached to the utility of future individuals. Neutrality becomes trickier when we depart from this simple case, meaning: (1) “non-identity” problems, where current choices change the identity of future individuals; (2) population-size variation, where current choices affect not merely the identity of future individuals, but the size of the world’s future population (this case raises the specter of what Derek Parfit terms “the repugnant conclusion,” i.e., that dramatic reductions in the average level of individual well-being might be compensated for by increases in population size); or (3) an infinite population. The Article grapples with the difficult question of outfitting a prioritarian SWF to handle non-identity problems, population-size variation, and infinite populations. It tentatively suggests that a measure of neutrality can be maintained even in these cases. (shrink)
