We are often faced with choices that involve the weighing of people's lives against each other, or the weighing of lives against other good things. These are choices both for individuals and for societies. A person who is terminally ill may have to choose between palliative care and more aggressive treatment, which will give her a longer life but at some cost in suffering. We have to choose between the convenience to ourselves of road and air travel, and the lives (...) of the future people who will be killed by the global warming we cause, through violent weather, tropical disease, and heat waves. We also make choices that affect how many lives there will be in the future: as individuals we choose how many children to have, and societies choose tax policies that influence people's choices about having children. These are all problems of weighing lives. How should we weigh lives? Weighing Lives develops a theoretical basis for answering this practical question. It extends the work and methods of Broome's earlier book Weighing Goods to cover the questions of life and death. Difficult problems come up in the process. In particular, Weighing Lives tackles the well-recognized, awkward problems of the ethics of population. It carefully examines the common intuition that adding people to the population is ethically neutral - neither a good nor a bad thing - but eventually concludes this intuition cannot be fitted into a coherent theory of value. In the course of its argument, Weighing Lives examines many of the issues of contemporary moral theory: the nature of consequentialism and teleology; the transitivity, continuity, and vagueness of betterness; the quantitative conception of wellbeing; the notion of a life worth living; the badness of death; and others. This is a work of philosophy, but one of its distinctive features is that it adopts some of the precise methods of economic theory (without introducing complex mathematics). Not only philosophers, but also economists and political theorists concerned with the practical question of valuing life, should find the book's conclusions highly significant to their work.

This essay deals with the question of the morality of abortion and infanticide. The fundamental ethical objection traditionally advanced against these practices rests on the contention that human fetuses and infants have a right to life, and it is this claim that is the primary focus of attention here. Consequently, the basic question to be discussed is what properties a thing must possess in order to have a serious right to life. The approach involves defending, then, a basic principle specifying (...) a condition living things must satisfy to have a serious right to life, and the answer given makes it unlikely that this condition is satisfied by human fetuses and infants, though this tentative conclusion could be altered by future scientific studies of the development of the human brain. As things stand at the moment, however, it seems unlikely that developing humans acquire the physical basis of the psychological capacities on which the right to continued existence rests, and therefore unless there are other substantial objections to abortion and infanticide that undercut the above line of thought, the conclusion is that such practices are not intrinsically wrong.

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.

A volume of philosophical studies, centred on problems of personal identity and extending to related topics in the philosophy of mind and moral philosophy.

The topic of personal identity has prompted some of the liveliest and most interesting debates in recent philosophy. In a fascinating new contribution to the discussion, Peter Unger presents a psychologically aimed, but physically based, account of our identity over time. While supporting the account, he explains why many influential contemporary philosophers have underrated the importance of physical continuity to our survival, casting a new light on the work of Lewis, Nagel, Nozick, Parfit, Perry, Shoemaker, and others. Deriving from his (...) discussion of our identity itself, Unger produces a novel but commonsensical theory of the relations between identity and some of our deepest concerns. In a conservative but flexible spirit, he explores the implications of his theory for questions of value and of the good life. (shrink)

Advances in technology have made it possible for us to take actions that affect the numbers and identities of humans and other animals that will live in the future. Effective and inexpensive birth control, child allowances, genetic screening, safe abortion, in vitro fertilization, the education of young women, sterilization programs, environmental degradation and war all have these effects. Although it is true that a good deal of effort has been devoted to the practical side of population policy, moral theory has (...) not dealt adequately with the new possibilities. The dilemma faced by moral theory is that traditional theories cannot answer moral questions involving the creation of people. Two related problems arise. The first concerns numbers: how many people should there be? The second asks what sort of people should live and what their levels of well-being should be. Conventional social-contract theories, including the work of Rawls (1971), are restricted to situations with a fixed number of individuals. Sumner (1978) attempts to extend a Rawlsian veil-of-ignorance approach to possible people but is aware of the difficulties involved. The main problem is that possible people must be thought to benefit when they move from non-existence to existence, a view that we reject (see Section 1, Heyd, 1992, Chapter 1; McMahan, 1996a; Parfit, 1984, Appendix G). Rights-based and duty-based theories suffer from a similar problem; there must be a person who has the right or a person to whom the duty is owed (see McMahan, 1981). (shrink)

How many people should there be? Can there be overpopulation: too many people living? I shall present a puzzling argument about these questions, show how this argument can be strengthened, then sketch a possible reply.

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)

Few subjects have generated so many newspaper headlines and such heated controversy as the treatment, or non-treatment, of handicapped newborns. In 1982, the case of Baby Doe, a child born with Down's syndrome, stirred up a national debate in the United States, while in Britain a year earlier, Dr. Leonard Arthur stood trial for his decision to allow a baby with Down's syndrome to die. Government intervention and these recent legal battles accentuate the need for a reassessment of the complex (...) issues involved. This volume--by two authorities on medical ethics--presents a philosophical analysis of the subject based on particular case studies. Addressing the doctrine of the absolute sanctity of life, Singer and Kuhse examine some actual cases where decisions have been reached; consider the criteria for making these decisions; investigate the differences between killing and letting die; compare Western attitudes and practices with those of other cultures; and conclude by proposing a decision-making framework that offers a rational alternative to the polemics and confusion generated by this highly controversial topic.

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.

Warren Quinn was widely regarded as a moral philosopher of remarkable talent. This collection of his most important contributions to moral philosophy and the philosophy of action has been edited for publication by Philippa Foot. Quinn laid out the foundations for an anti-utilitarian moral philosophy that was critical of much contemporary work in ethics, such as the anti-realism of Gilbert Harman and the neo-subjectivism of Bernard Williams. Quinn's own distinctive moral theory is developed in the discussion of substantial, practical moral (...) issues. For example, there are important pieces here on the permissibility of abortion, the justification of punishing criminals when no particular good seems likely to result, and on the distinction between killing and allowing to die, a distinction crucial to the subject of euthanasia and other topics in medical ethics. The volume would be ideally suited to upper-level undergraduate courses and graduate seminars on the foundations of ethics. (shrink)

For thirty years, Peter Singer's Practical Ethics has been the classic introduction to applied ethics. For this third edition, the author has revised and updated all the chapters and added a new chapter addressing climate change, one of the most important ethical challenges of our generation. Some of the questions discussed in this book concern our daily lives. Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? Am (...) I doing something wrong if my carbon footprint is above the global average? Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research and euthanasia; political violence and terrorism; and the preservation of our planet's environment. This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think about how she or he ought to live. (shrink)

We all have beliefs, even strong convictions, about what is just and fair in our social arrangements. How should these beliefs and the theories of justice that incorporate them guide our thinking about practical matters of justice? This wide-ranging collection of essays by one of the foremost medical ethicists in the USA explores the claim that justification in ethics, whether of matters of theory or practice, involves achieving coherence between our moral and non-moral beliefs. Amongst the practical issues addressed in (...) the volume are the design of health-care institutions, the distribution of goods between the old and the young, and fairness in hiring and firing. In combining ethical theory and practical ethics this volume will prove especially valuable to philosophers concerned with ethics and applied ethics, political theorists, bioethicists, and others involved in the study of public policy.

This is the earliest critical discussion in the context of modern/contemporary philosophy in the analytical tradition arguing that somebody with a reasonably stable character and the company of the right people would be able to enjoy eternity.

A comprehensive study of the ethics of killing in cases in which the metaphysical or moral status of the individual killed is uncertain or controversial. Among those beings whose status is questionable or marginal in this way are human embryos and fetuses, newborn infants, animals, anencephalic infants, human beings with severe congenital and cognitive impairments, and human beings who have become severely demented or irreversibly comatose. In an effort to understand the moral status of these beings, this book develops and (...) defends distinctive accounts of the nature of personal identity, the evaluation of death, and the wrongness of killing. The central metaphysical claim of the book is that we are neither nonmaterial souls nor human organisms but are instead embodied minds. In ethical theory, one of the central claims is that the morality of killing is not unitary; rather, the principles that determine the morality of killing in marginal cases are different from those that govern the killing of persons who are self‐conscious and rational. Another important theme is that killing in marginal cases should be evaluated in terms of the impact it would have on the victim at the time rather than on the value of the victim's life as a whole. What primarily matters is how killing would affect that which would be rational for the victim to care about at the time of death. By appealing to various foundational claims about identity, death, and the morality of killing, this book yields novel conclusions about such issues as abortion, prenatal injury, infanticide, the killing of animals, the significance of brain death, the termination of life support in cases of persistent vegetative state, the use of anencephalic infants as sources of organs for transplantation, euthanasia, assisted suicide, and advance directives in cases of dementia. In particular, the book defends the moral permissibility of abortion, infanticide, and euthanasia in certain cases and argues that brain death is not the appropriate criterion of death either for a person or a human organism.

What is death? Do people survive death? What do we mean when we say that someone is "dying"? Presenting a clear and engaging discussion of the classic philosophical questions surrounding death, this book studies the great metaphysical and moral problems of death. In the first part, Feldman shows that a definition of life is necessary before death can be defined. After exploring several of the most plausible accounts of the nature of life and demonstrating their failure, he goes on to (...) propose his own conceptual scheme for death and related concepts. In the second part, Feldman turns to ethical and value-theoretical questions about death. Addressing the ancient Epicurean ethical problem about the evil of death, he argues that death can be a great evil for those who die, even if they do not exist after death, because it may deprive them of the goods they would have enjoyed if they had continued to live. Confrontations with the Reaper concludes with a novel consequentialist theory about the morality of killing, applying it to such thorny practical issues as abortion, suicide, and euthanasia.

According to impersonal moralities, welfare is good, period. Therefore, it is good that welfare is realised, whether by the benefiting of individuals who already exist or by the bringing of new...

In our lives, we aim to achieve welfare for ourselves, that is, to live good lives. But we also have another, more impartial perspective, where we aim to balance our concern for our own welfare against a concern for the welfare of others. This is a perspective of justice. Nils Holtug examines these two perspectives and the relations between them.

By a potential person I shall mean an entity which is not now a person but which is capable of developing into a person, given certain biologically and/or technologically possible conditions. This is admittedly a narrower sense than some would attach to the term ‘potential'. After all, people of the twenty-fifth century, if such there will be, are in some sense potential people now, even though the specific biological entities from which they will develop, i.e. the particular gametes or concepti, (...) do not yet exist. For there do exist, in the reproductive capacities of people now living and in the earth's resources, conditions adequate to produce these future people eventually, provided of course that various possible catastrophes are avoided. Indeed, in some sense of ‘potential’ there have been countless billions of potential people from the beginning of time. But I am concerned not with such remote potentialities but with currently existing entities that are capable of developing into people. (shrink)

Just because an angel is better than a stone, it does not follow that two angels are better than one angel and one stone. So said Aquinas (Summa contra Gentiles III, 71), and the sentiment was echoed by Leibniz. In section 118 of the Theodicy he wrote: "No substance is either absolutely precious or absolutely contemptible in the sight of God. It is certain that God attaches more importance to a man than to a lion, but I do not know (...) that we can bc sure that he prefers one man to an entire species of lions." Even Kant was bitten by this bug. In one of his pre-Critical works he was moved to say, à propos of lice, that even though they “may in our eyes be as worthless as you like, nevertheless it is of more consequence to Nature to conserve this species as a whole than to conserve a small number of members of a superior species." In these passages Aquinas, Leibniz, and Kant gave expression to a distinctive and interesting view about the value of animal species and animal populations. At its simplest, this is the view that there is a special value in the existence of animal species or in the existence of a wide variety of different animal species. But the view also goes deeper than this. An animal species, after all, is nothing over and above the individual animals which make it up, and the value which it contributes to the world must therefore be some function of the values contributed by those individual animals. At the deepest level, what the view expressed by Aquinas, Leibniz, and Kant holds is that the value which an individual animal contributes to thc world is not constant but varies with the number..
