This collection of essays, written by noted scholars and theorists, covers everything from the practical to the theoretical, and investigates the obligations we have to future persons, ranging from our own future offspring to distant future generations.

Melinda A. Roberts and David T. Wasserman 1 Purpose of this Collection What are our obligations with respect to persons who have not yet, and may not ever, come into existence? Few of us believe that we can wrong those whom we leave out of existence altogetherthat is, merely possible persons. We may think as well that the directive to be fruitful, and multiply, and replenish the earth 1 does not hold up to close scrutiny. How can it be wrong to decline to bring ever more people into existence? At the same time, we think we are clearly ob- gated to treat future personspersons who don't yet but will existin accordance with certain stringent standards. Bringing a person into an existence that is truly awfulnot worth havingcan be wrong, and so can bringing a person into an existence that is worth having when we had the alternative of bringing that same person into an existence that is substantially better. We may think as well that our obligations with respect to future persons are triggered well before the point at which those persons commence their existence. We think it would be wrong, for example, to choose today to turn the Earth of the future into a miserable place even if the victims of that choice do not yet exist.

Examines what we owe future persons from both moral and legal perspectives Deeply probes particular concerns in areas ranging from the new reproductive technologies to the structure of morality Ranges from the practical (is it wrong to bring an impaired child into existence?) to the theoretical (can bad acts be bad for no one?) Is written by the most noted scholars and theorists amongst those working today on matters relating to future persons Extends and applies the powerful work Derek Parfit commenced in his brilliant and influential book Reasons and Persons

Klappentext

This collection of essays investigates the obligations we have in respect of future persons, from our own future offspring to distant future generations. Can we harm them? Can we wrong them? Can the fact that our choice brings a worse off person into existence in place of a better off but "nonidentical" person make that choice wrong?

We intuitively think we are obligated to treat future persons in accordance with certain stringent standardsroughly those we think apply to our treatment of existing persons. We think we ought to create better lives for at least some future persons when we can do so without making things worse for too many existing or other future persons. We think it would be wrong to engage in risky behaviors today that will have clearly adverse effects for the children we intend one day to conceive. And we think it would be wrong to act today in a way that would turn the Earth of the future into a miserable place.

Each of these intuitive points is, however, challenged by the nonidentity problem. That problem arises from the observation that future persons often owe their very existence to choices that appear to make things worse for those same persons. New reproductive technologies, for example, can be both risky and essential to one person's coming into existence in place of a "nonidentical" other or no one at all. But so can a myriad of other choices, whether made just prior to conception or centuries beforechoices that seem to have nothing to do with procreation but in fact help to determine the timing and manner of conception of any particular future person and thus the identity of that person. Where the person's life is worth living, it is difficult to see how he or she has been harmed, or made worse off, or wronged, by such an identity-determining choice. We then face the full power of the nonidentity problem: if the choice is not bad for the future person it seems most adversely to affect, then onwhat basis do we say that choice is wrong?

The nonidentity problem has implications for moral theory, population policy, procreative choice, children's rights, bioethics, environmental ethics, the law and reparations for historical injustices. The contributors to this collection offer new understandings of the nonidentity problem and evaluate an array of proposed solutions to it. Aimed at philosophers, legal scholars, bioethicists and students in all these disciplines, this collection is a thorough exploration of one of the most fascinating and important moral issues of our time.
