Is it fair to leave the next generation a public debt? Is it defensible to impose legal rules on them through constitutional constraints? From combating climate change to ensuring proper funding for future pensions, concerns about ethics between generations are everywhere. In this volume sixteen philosophers explore intergenerational justice. Part One examines the ways in which various theories of justice look at the matter. These include libertarian, Rawlsian, sufficientarian, contractarian, communitarian, Marxian and reciprocity-based approaches. In Part Two, the authors look (...) more specifically at issues relevant to each of these theories, such as motivation to act fairly towards future generations, the population dimension, the formation of preferences through education and how they impact on our intergenerational obligations, and whether it is fair to rely on constitutional devices.

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.

Theories of intergenerational obligations usually take the shape of theories of distributive (social) justice. The complexities involved in intergenerational obligations force theorists to simplify. In this article I unpack two popular simplifications: the inevitability of future generations, and the Hardinesque assumption that future individuals are a burden on society but a benefit to parents. The first assumption obscures the fact that future generations consist of individuals whose existence can be a matter of voluntary choice, implying that there are individuals who (...) are responsible and accountable for that choice and for its consequences. The second assumption ignores the fact that the benefits and burdens of future individuals are complex, and different for different “beneficiaries” or “victims.” Introducing individual responsibility for procreation as a (crucially) relevant variable, and allowing a more sophisticated understanding of the impact of new individuals, generates grounds to prioritize the individual’s interest in responsibility for (creating and equipping) future individuals over any collective intergenerational obligation. I illustrate this by introducing a series of moral duties that take precedence over, and perhaps even void, possible collective redistributive duties. (shrink)

Faced with at least two major challenges, namely, worldwide poverty and inequalities, and ecological changes, our world is confronted with the issue of balancing the concern for the social needs of the present generation, as an expression of intragenerational responsibilities, with the care for the environment for future generations, as fulfilling intergenerational responsibilities. After demonstrating how the philosophical debate indeed validates the notion of intergenerational responsibilities, this article seeks to investigate the relationship between inter- and intragenerational responsibilities. Whereas this relationship (...) is often considered as a troubled and conflicting one, I aim to show that there are reasons to link the problems of global justice and ecological degradation. It will be argued that both global inequality and the ecological crisis are moral problems caused by a particular kind of development philosophy and lifestyle. Consequently, people have a responsibility to take these social and ecological issues into account in their daily lives. In the last section, some theological reflections are provided with regard to the idea of intergenerational responsibilities, their relationship to intragenerational responsibilities, and the contribution of theology as an inspirational source for change.

I shall argue here that the reason supererogatory acts are not obligatory is that they require too much personal sacrifice, and that in order for an act to be supererogatory, it must have a kind of result that you would have an obligation to bring about if you could do so with no personal sacrifice. I further argue that traditional utilitarianism should be modified so as not to treat supererogatory acts as obligatory.

In Morals by Agreement David Gauthier proposes four criteria for classifying a society's advancement toward ‘higher stages of human development.' Significantly, these criteria — material well-being, breadth of opportunity, average life-span, and density of population — do not include as an equally valuable achievement the society's capacity to sustain its standard of living. Nonetheless Gauthier presents three arguments intended to show that a community founded on his distributive theory will view depletionary resource policies as unreasonable and unacceptable. I shall contend (...) that these arguments do not succeed in motivating sustainable rates of resource exploitation. Furthermore, I argue that if truly just and rational resource use policies can be arrived at, such policies could only succeed by employing a conception of property rights substantially different from Gauthier's.

There is a special problem with respect to our obligations to future generations which is that we can benefit or harm them but that they cannot benefit or harm us. Goodin summarizes the point well:No analysis of intergenerational justice that is cast even vaguely in terms of reciprocity can hope to succeed. The reason is the one which Addison… puts into the mouth of an Old Fellow of College, who when he was pressed by the Society to come into something (...) that might rebound to the good of their Successors, grew very peevish. ‘We are always doing’ says he, ‘something for Posterity, but I would fain see Posterity do something for us’.

While in the realm of scholarly debate on intergenerational justice the mechanism of a transgenerational intertwinement has been often adopted as a chief conceptual device in view of overcoming ethical short-termism and legitimizing duties towards future generations, this paper aims at showing that there are good reasons for considering the opposite outcome. Drawing on three paradigmatic examples taken from three mainstream approaches in the debate—Rawls’s contractualism, Gauthier’s contractarianism, and indirect reciprocity—I will show how the grammar of presentism is still largely (...) operative under the surface of theories explicitly recurring to such a device and thereby advocating a chain of duties capable to reach the remote future. A short closing section will be devoted to endorsing a radical reorientation in ethics, such that a direct link to future invocations will be considered as a promising strategy for genuinely justifying intergenerational obligations.

Do non-persons have moral rights? I will suppose this question can best be answered by inquiring whether some animals and/or environmental objects have moral rights, for if any non-persons are possessors of rights, animals and/or environmental objects are the most plausible candidates. As so interpreted, this question has received an extraordinary amount of recent attention from philosophers. Arguments have been offered and defended; rebuttals have appeared in print. Yet, so far as I am aware, no one has presented a clear (...) and accurate statement of what turns on the issue of whether non-persons have moral rights. In the absence of such a statement, philosophers are likely to be at sea in determining on which side of the controversy their initial sympathies lie. In this paper it is my central concern to help clarify what turns on the issue of whether non-persons are possessors of moral rights, rather than to argue decisively for one position or the other.

I defend the 'Repugnant' Conclusion that for any possible population of happy people, a population containing a sufficient number of people with lives barely worth living would be better. Four lines of argument converge on this conclusion, and the conclusion has a simple, natural theoretical explanation. The opposition to the Repugnant Conclusion rests on a bare appeal to intuition. This intuition is open to charges of being influenced by multiple distorting factors. Several theories of population ethics have been devised to (...) avoid the Repugnant Conclusion, but each generates even more counterintuitive consequences. The intuition opposing the Repugnant Conclusion is thus among the best candidates for an intuition that should be revised. (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)

Some key political challenges today, e.g. climate change, are future oriented. The intergenerational setting differs in some notable ways from the intragenerational one, creating obstacles to theorizing about intergenerational justice. One concern is that as the circumstances of justice do not pertain intergenerationally, intergenerational justice is not meaningful. In this paper, I scrutinize this worry by analysing the presentations of the doctrine of the circumstances of justice by David Hume and John Rawls. I argue that we should accept the upshot (...) of their idea, that justice is context sensitive, even if this at first sight seems to invalidate intergenerational justice. On the basis of moral constructivism, I subsequently provide a fresh reading of the doctrine according to which it conveys the idea that justice is the solution to a practical problem. However, as the problem background is evolving, we need to properly characterize the relevant practical problem in order to make ethical theorizing relevant. Contrary to what has been claimed, the circumstances of justice do not then clash with intergenerational justice, but are the necessary presuppositions for its advancement. (shrink)

This article argues that it is possible to act paternalistically towards future people, as long as the following requirements are met: the act/choice is not such that it will prevent the future person from coming into existence; the action/choice is such that it can be taken by the future person herself without significant disadvantage to her; and the act/choice is not such that there is significant uncertainty at the time of choice about the preferences of the future person. I argue (...) that the possibility of acting paternalistically towards future people is of practical as well as theoretical importance. This is true since some of the policies we might choose to pursue on behalf of future people are paternalistic, in particular constitutional policies implemented because we do not trust future people to choose wisely. I end the paper by pointing out why it is valuable to approach intergenerational issues through both the paternalistic prism and the prism of theories of justice. (shrink)

Ultimately this book provides a theory of intergenerational justice that is both intellectually robust and practical with wide applicability to law and policy.

In Derek Parfit's original formulation the Repugnant Conclusion is characterized as follows: “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” (Parfit 1984). The Repugnant Conclusion highlights a problem in an area of ethics which has become known as population ethics . The (...) last three decades have witnessed an increasing philosophical interest in questions such as “Is it possible to make the world a better place by creating additional happy creatures?” and “Is there a moral obligation to have children?” The main problem has been to find an adequate theory about the moral value of states of affairs where the number of people, the quality of their lives, and their identities may vary. Since, arguably, any reasonable moral theory has to take these aspects of possible states of affairs into account when determining the normative status of actions, the study of population ethics is of general import for moral theory. As the name indicates, Parfit finds the Repugnant Conclusion unacceptable and many philosophers agree. However, it has been surprisingly difficult to find a theory that avoids the Repugnant Conclusion without implying other equally counterintuitive conclusions. Thus, the question as to how the Repugnant Conclusion should be dealt with and, more generally, what it shows about the nature of ethics has turned the conclusion into one of the cardinal challenges of modern ethics.
