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.

Egoism can be a descriptive or a normative position. Psychological egoism, the most famous descriptive position, claims that each person has but one ultimate aim: her own welfare. Normative forms of egoism make claims about what one ought to do, rather than describe what one does do. Ethical egoism claims that it is necessary and sufficient for an action to be morally right that it maximize one's self-interest. Rational egoism claims that it is necessary and sufficient for an action to (...) be rational that it maximize one's self-interest. (shrink)

In recent decades, P. F. Strawson’s “Freedom and Resentment” (1962) has had an enormous influence on philosophical views of moral responsibility. Many contemporary views follow Strawson in centering questions of responsibility on the appropriateness of certain attitudes in our interpersonal relations, especially attitudes of blame and anger, rather than on the abstract nature of free will. Strawson’s influence has in many ways been beneficial, but the prevailing Strawsonian views have taken on some of the more dubious tendencies of contemporary moral (...) philosophy. Among them is the tendency to think of our ethical relations narrowly in terms of the sort of respect that we owe friends and strangers alike, while neglecting attitudes of concern and understanding. This tendency distorts our views of our ethical relations and how we should respond to one another’s wrongful conduct. To correct those distortions, I retrieve insights from older traditions of ethical thought—especially Platonic, Stoic, and Christian traditions—which give love and understanding a central place in our ethical relations, along with respect. These traditions, which have profoundly shaped the development of Western ethical thought, are unduly neglected in contemporary moral philosophy. By joining the insights of these traditions with the insights of Strawsonian views of responsibility, I believe we can articulate a more complete and compelling view of ethical life and responsibility.

On person-affecting views in population ethics, the moral import of a person’s welfare depends on that person’s temporal or modal status. These views typically imply that – all else equal – we’re never required to create extra people, or to act in ways that increase the probability of extra people coming into existence. -/- In this paper, I use Parfit-style fission cases to construct a dilemma for person-affecting views: either they forfeit their seeming-advantages and face fission analogues of the problems (...) faced by their rival impersonal views, or else they turn out to be not so person-affecting after all. In light of this dilemma, the attractions of person-affecting views largely evaporate. What remains are the problems unique to them. (shrink)
