Suppose we discover how we could live for a thousand years, but in a way that made us unable to have children. Everyone chooses to live these long lives. After we all die, human history ends, since there would be no future people. Would that be bad? Would we have acted wrongly? Some pessimists would answer No. These people are saddened by the suffering in most people’s lives, and they believe it would be wrong to inflict such suffering on others (...) by having children. In earlier centuries, this bleak view was fairly plausible. But our successors would be able to prevent most human suffering. Some optimists would also answer No . . . These [views] are, I believe, deeply mistaken. Given what our successors could achieve in the next million or billion years, here and elsewhere in our galaxy, it would be likely to be very much worse if there were no future people. (shrink)

Many are committed to the idea that the present generation has obligations to future generations, for example, obligations to preserve the environment and certain natural resources for those generations. However, some philosophers want to explain why we have these obligations in terms of correlative rights that future persons have against persons in the present. Attributing such rights to future persons is controversial, for there seem to be compelling arguments against the position. According to the “nonexistence” argument, future persons cannot have (...) rights (and so should not be attributed rights) because they do not exist. According to the “no-satisfaction” argument, future persons cannot have a right to resources that do not exist at the time of their existence because such a right could not, in principle, be satisfied. In this paper, I will argue that an eternalist ontology of time provides the resources for satisfactorily responding to both the nonexistence and the no-satisfaction arguments. (shrink)

Many people believe that we have responsibility towards the distant future, but exactly how far this responsibility reaches and how we can find a reasonable ethical foundation for it has not been answered in any definitive manner. Future people have no power over us, they form no part of our moral community and it is unclear how we can represent them in a possible original position. All these problems can be circumvented when you take an impersonal decision criterion like maximizing (...) total or average utility. Such a sum-ranking criterion is neutral with respect to distance in time or space: my utility, my neighbour's and that of our descendants all carry the same weight. This makes future people an integral part of present decisions. Time-neutrality was defended by, among others, Sidgwick, Pigou and Ramsey. (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.

Several philosophers argue that individuals have an interest-protecting right to parent; specifically, the interest is in rearing children whom one can parent adequately. If such a right exists it can provide a solution to scepticism about duties of justice concerning distant future generations and bypass the challenge provided by the non-identity problem. Current children - whose identity is independent from environment-affecting decisions of current adults - will have, in due course, a right to parent. Adequate parenting requires resources. We owe (...) duties of justice to current children, including the satisfaction of their interest-protecting rights; therefore we owe them the conditions for rearing children adequately in the future. But to engage in permissible parenting they, too, will need sufficient resources to ensure their own children's future ability to bring up children under adequate conditions. Because this reasoning goes on ad infinitum it entails that each generation of adults owes its contemporary generation of children at least those resources that are necessary for sustaining human life indefinitely at an adequate level of wellbeing.

This paper analyses the main challenges to the idea that we should and can represent future generations in our present policymaking. It argues that these challenges can and should be approached from the perspective of human rights. To this end it introduces and sketches the main features of a human rights framework derived from the moral theory of Alan Gewirth. It indicates how this framework can be grounded philosophically, sketches the main features and open questions of the framework and its (...) grounding, and shows how it can be used to deal with the challenges to the idea that future generations have rights that can be represented in our policymaking.

In a familiar interpretation, the Non-Identity Problem claims that persons whose existence depends on a seemingly harmful action cannot in fact be harmed through such an action. It is often objected that the persons in question can nevertheless be wronged through a violation of their rights. However, this objection seems to fail because these persons would readily waive any violated right in order to come into existence. The present article will analyze this Waiver Counter Argument in detail and show why (...) it does not succeed. First, it is necessary to distinguish between a prospective and a retrospective waiver scenario. In the prospective scenario an imagined person must consider whether she wants to waive a right in order to come into existence. In the retrospective scenario a person is asked whether she would prefer a wronged existence to never having been born. In both scenarios the conditions of a legitimate waiver of rights are not met, but for different reasons. On this basis, an argument against NIP can be developed. (shrink)

This book, written by four internationally renowned bioethicists and first published in 2000, was the first systematic treatment of the fundamental ethical issues underlying the application of genetic technologies to human beings. Probing the implications of the remarkable advances in genetics, the authors ask how should these affect our understanding of distributive justice, equality of opportunity, the rights and obligations as parents, the meaning of disability, and the role of the concept of human nature in ethical theory and practice. The (...) book offers a historical context to contemporary debate over the use of these technologies by examining the eugenics movement of the late nineteenth and early twentieth centuries. The questions raised in this book will be of interest to any reflective reader concerned about science and society and the rapid development of biotechnology, as well as to professionals in such areas as philosophy, bioethics, medical ethics, health management, law, and political science.

Unprecedented advances in medicine, genetic engineering, and demographic forecasting raise new questions that strain the categories and assumptions of traditional ethical theories. Heyd's approach resolves many paradoxes in intergenerational justice, while offering a major test case for the profound problems of the limits of ethics and the nature of value.

G. A. Cohen was one of the most gifted, influential, and progressive voices in contemporary political philosophy. At the time of his death in 2009, he had plans to bring together a number of his most significant papers. This is the first of three volumes to realize those plans. Drawing on three decades of work, it contains previously uncollected articles that have shaped many of the central debates in political philosophy, as well as papers published here for the first time. (...) In these pieces, Cohen asks what egalitarians have most reason to equalize, he considers the relationship between freedom and property, and he reflects upon ideal theory and political practice. Included here are classic essays such as "Equality of What?" and "Capitalism, Freedom, and the Proletariat," along with more recent contributions such as "Fairness and Legitimacy in Justice," "Freedom and Money," and the previously unpublished "How to Do Political Philosophy." On ample display throughout are the clarity, rigor, conviction, and wit for which Cohen was renowned. Together, these essays demonstrate how his work provides a powerful account of liberty and equality to the left of Ronald Dworkin, John Rawls, Amartya Sen, and Isaiah Berlin. (shrink)

Principles of sufficiency are widely discussed in debates about distributive ethics. However, critics have argued that sufficiency principles are vulnerable to important objections. This paper seeks to clarify the main claims of sufficiency principles and to examine whether they have something distinctive and plausible to offer. The paper argues that sufficiency principles must claim that we have weighty reasons to secure enough and that once enough is secured the nature of our reasons to secure further benefits shifts. Having characterized sufficientarianism (...) in this way, the paper shows that the main objections to the view can be avoided; that we can examine the plausibility of sufficiency principles by appealing to certain reasons that support a shift; and that we should be optimistic about the prospects for sufficientarianism because many of our strongest reasons seem to be of this sort. This shift, I claim, is the overlooked grain of truth in sufficientarianism. (shrink)

Non-Identity arguments have a pervasive but sometimes counter-intuitive grip on certain key areas in ethics. As a result, there has been limited success in supporting the alternative view that our choices concerning future generations can be considered harmful on any sort of person-affecting principle. However, as the Non-Identity Problem relies overtly on certain metaphysical assumptions, plausible alternatives to these foundations can substantially undermine the Non-Identity argument itself. In this paper, I show how the pervasive force and nature of Non-Identity arguments (...) rely upon a specific adoption of a theory of modality and identity and how adopting an alternative account of modality can be used to reject many conclusions formed through Non-Identity type arguments. By using Lewis’s counterpart-theoretic account to understand ways we might have been, I outline the basis of a modal account of harm that incorporates a person-affecting aspect. This, in turn, has significant implications for ethical decision-making in areas such as reproductive choice and the welfare of future generations. (shrink)

A natural way of viewing compensation is to see it as the restoration of a good or level of well-being which someone would have enjoyed if he had not been adversely affected by the act of another. This view underlies Nozick’s assertion that “something fully compensates … person X for Y’s action A if X is no worse off receiving it, Y having done A, than X would have been without receiving it if Y had not done A”; and it (...) has been held by many others as well. Because the notion that compensation is the restoration of a good which a person would have had but for the act of another is so pervasive, I shall refer to it as the official view of compensation. One noteworthy feature of the official view is the ease with which it allows compensation to be justified in particular cases. If compensation is just the restoration of a good which one would have had if the ordinary course of things had not been disrupted, then to provide a prima facie justification of it, one need only argue that the natural course of things should not have been disrupted in the first place.

Act Utilitarianisms divide into Total and Average versions. Total versions seem to imply Parfit’s “Repugnant Conclusion”. Average versions are proposed in part to avoid the Repugnant Conclusion, but these are subject to “Mere Addition” arguments as detailed by Hudson in “The Diminishing Marginal Value of Happy People”. Thus, various intermediate versions of utilitarianism, such as the one investigated by Hurka in “Value and Population Size”, take on interest. But Hudson argues that such compromise theories are subject to the mere addition (...) arguments, and are therefore no improvement over Average Utilitarianism. I disagree: some such compromise solutions escape Hudson’s Mere Addition arguments. (shrink)

Should the current members of a community compensate the victims of their ancestor’s emissions of greenhouse gases? I argue that the previous generation of polluters may not have been morally responsible for the harms they caused.I also accept the view that the polluters’ descendants cannot be morally responsible for their ancestor’s harmful emissions. However, I show that, while granting this, a suitably defined notion of moral free-riding may still account for the moral obligation of the polluters’ descendants to compensate the (...) current victims of their ancestors’ actions. A concept of transgenerational free-riding is defined. Objections to the idea of using free-riding as part of a theory of justice are rejected. Two different views of moral free-riding are contrasted, with consequences for the amount of compensation to be exigible from the polluters’ descendants. Some final considerations are devoted to the possible relevance of this free-riding-based view for other issues of historical injustice. (shrink)

Derek Parfit has famously pointed out that ‘total’ utilitarian views, such as classical hedonistic utilitarianism, lead to the conclusion that, to each population of quite happy persons there corresponds a more extensive population with people living lives just worth living, which is better. In particular, for any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better, (...) even though its members have lives that are barely worth living. This world is better if the sum total of well-being is great enough, and it is great enough if only enough sentient beings inhabit it. This conclusion has been considered by Parfit and others to be ‘repugnant’. (shrink)

Parfit's requirements for an ideal Theory X cannot be fully met since the Mere Addition Principle and Non-Antiegalitarianism imply the Repugnant Conclusion: Theory X does not exist. However, since the Repugnant Conclusion is really compelling, the Impersonal Total Principle should be adopted for impartial comparisons concerning future generations. Nevertheless, where our own interests are affected, we may yet choose to be partial, trading off our concern for future goodness with our self-interests. Theory X' meets all Parfit's requirements except the Mere (...) Addition Principle in less compelling cases. (shrink)

It has been argued by some that the present non-existence of future persons entails that whatever obligations we have towards them are not based on rights which they have or might come to have. This view is refuted. It is argued that the present non-existence of future persons is no impediment to the attribution of rights to them. It is also argued that, even if the present non-existence of future persons were an impediment to the attribution of rights to them, (...) the rights they will have when they come into existence constitute a constraint on present actions. Both arguments build on a suggestion of Joel Feinberg's. Next, three arguments are considered which, while they do not highlight the non-existence issue, are related to it. The view that the causal dependence, of (some) future people on present policies, erodes or weakens the claim that rights considerations should constrain our present actions concerning them, is considered and rejected. The view that future people can only have rights to what is available at the time at which these people come into existence is considered and rejected. So too is the view that the attribution of rights to future people involves, in virtue of resource scarcity, an unacceptable arbitrariness. (shrink)

The question I address in this paper is whether and under what conditions it is morally right to bring a person into existence. I defend the commonsensical thesis that, other things being equal, it is morally wrong to create a person who will be below some threshold of quality of life, even if the life of this potential person, once created, will nevertheless be worth living. However commonsensical this view might seem, it has shown to be problematic because of the (...) so-called 'Non-Identity Problem'. Both utilitarian and rights-based approaches have been unable to provide a solution to this problem. I rest my thesis on two premises: that causing a disability or impairment in a future person is prima facie wrong, so long as we can avoid causing such a disability to that very person; and that reproduction, under normal conditions, is prima facie morally indifferent. From these two premises, I conclude that it is prima facie wrong to bring into existence a person with a non-trivial disability or impairment (which might be, nonetheless, compatible with a worthwhile life), even if the only available alternative is to remain childless.

Exploring the peculiar nature of future generations and concluding that types of future people is the most promising object on which to project our concern for future generations the article poses two main questions: “Can future people have rights?” and, if so, “Do they in fact have any rights?” The article first explains why the non-existence of future people raises doubts whether future generations can have rights. Within the philosophical literature, the leading approach explaining how future people can, nevertheless, have (...) rights argues that they have rights as tokens of types of people. After presenting this account of the rights of future people and couching it in a jurisprudential context, this Article points out a possible deficiency in the approach’s metaphysical underpinnings. Assuming that future people can have rights the article goes on to explain that there is reason to doubt whether any such rights actually exist, which derive from the doubt whether future people will be harmed by most actions and choices in their prenatal past. According to what has come to be known as the “nonidentity argument,” actions and choices that are necessary parts of the causal chain leading up to the existence of a person cannot harm that person - had the act or choice not occurred that person would have never existed, and one is better off existing than not. Under the two prevalent theories of rights, the Will Theory and the Interest Theory, the nonidentity argument seemingly entails that future people have no rights. After exploring how this is the case, the conception of harm underlying the nonidentity argument is analyzed. Two types of interests future people may have in prenatal identity-determinative events (constitutive interests and threshold interests) are explored as possible sources of certain rights future people may have - the nonidentity argument notwithstanding. The article then elaborates and assesses the merits of these approaches. (shrink)

The paper considers the morality of nuclear energy development as it concerns future people, especially the creation of highly toxic nuclear wastes requiring long?term storage. On the basis of an example with many parallel moral features it is argued that the imposition of such costs and risks on the future is morally unacceptable. The paper goes on to examine in detail possible ways of escaping this conclusion, especially the escape route of denying that moral obligations of the appropriate type apply (...) to future people. The bulk of the paper comprises discussion of this philosophical issue, including many arguments against assigning obligations to the future drawn both from analyses of obligation and from features of the future such as uncertainty and indeterminacy. A further escape through appeal to moral conflict is also considered, and in particular two conflict arguments, the Poverty and Lights?going?out arguments are briefly discussed. Both these escape routes are rejected and it is concluded that if the same standards of behaviour are applied to the future as to the present, nuclear energy development is morally unacceptable.

The practice of conservation assumes that current persons have some obligations to future generations, but these obligations are complicated by a number of philosophical problems, chief among which is what Derek Parfit calls the Non-Identity Problem. Because our actions now will affect the identities of persons to be born in the distant future, we cannot say that those actions either benefit or harm those persons. Thus, a causal link between our acts and their consequences for particular persons is severed, and (...) the justification for conservation duties toward future generations undermined. I argue for an alternative justification for conservation in the capacity of foresight, which requires us to act not only upon duties that we have now, but also upon those that we will predictably have in the future. In this way, the future generations problem, at least as applied to conservation issues, is overcome. (shrink)

This article proposes an analysis of the doctrine of sufficiency. According to my reading, the doctrine's basic positive claim is ‘prioritarian’: benefiting x is of special moral importance where (and only where) x is badly off. Its negative claim is anti-egalitarian: most comparative facts expressed by statements of the type ‘x is worse off than y’ have no moral significance at all. This contradicts the ‘classical’ priority view according to which, although equality per se does not matter, whenever x is (...) worse off than y, at least some priority should be assigned to helping x. Section I elaborates and defends this reconstruction of the doctrine of sufficiency, and section II shows that the privileged utility level presumed within the sufficiency framework exists. (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..

In recent years there has been a good deal of discussion of equality’s place in the best account of distribution or distributive justice. One central question has been whether egalitarianism should give way to a principle requiring us to give priority to the worse off. In this article, I shall begin by arguing that the grounding of equality is indeed insecure and that the priority principle appears to have certain advantages over egalitarianism. But I shall then claim that the priority (...) principle itself is ungrounded and that the priority principle should itself give way to a sufficiency principle based — indirectly, via the notion of an impartial spectator — on compassion for those who are badly off.

The Human Genome Project will produce information permitting increasing opportunities to prevent genetically transmitted harms, most of which will be compatible with a life worth living, through avoiding conception or terminating a pregnancy. Failure to prevent these harms when it is possible for parents to do so without substantial burdens or costs to themselves or others are what J call “wrongful handicaps”. Derek Parfit has developed a systematic difficulty for any such cases being wrongs — when the harm could be (...) prevented only by preventing the existence of the individual who would have a worthwhile life even with the handicap, then bringing him into existence with the handicap does not make him worse off and so does not wrong him. I argue that a non “person‐affecting” principle requiring the avoidance of suffering and limited opportunity correctly accounts for cases of wrongful handicaps without requiring that the individuals with the handicap have been made worse off and therefore wronged. It is an advantage, not a difficulty, of this account that it does not imply that the person with the handicap has been wronged or is a victim with a special moral complaint. (shrink)
