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)

Derek Parfit's Reasons and Persons is a long, difficult and fascinating book, inside which three shorter, clearer and better books are struggling to get out. The third of these shorter but better books deals with the problem of Future Generations, and that is the book I want to discuss. In it Parfit tries, but fails, to find a theory—Theory X, he calls it—which will deal with various problems and issues which he develops, and in particular the issue which I will (...) call the Parfit Population Problem, the problem of how many people there ought to be. In this paper I offer not so much a theory as a suggestion as to what the solution might be. (shrink)

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.
