In "Futurc Generations: Further Problems,"‘ and Part Four of Reasons and Persons} Derek Pariit raises many perplexing questions. Although some think his ingenious arguments little more than delightful puzzles, I believe they challenge some of our deepest beliefs. In this article, I examine some of Pariit’s arguments, focusing mainly on "The Mere Addition Paradox." If my analysis is correct, Parfit’s arguments have extremely interesting and important implications that not even Pariit rcalized. In Part I, I present ParHt’s argument for the (...) Merc Addition Paradox, and show that given Pa.rHt’s assumptions, a radical conclusion seems t0 follow; the notion of "bctter th2m"—indced, even the notion of "aH things.. (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)

Temkin presents a new way of thinking about equality and inequality that challenges the assumptions of philosophers, welfare economists, and others, and has significant implications on both a practical and theoretical level.

Utilitarianism tells us that actions are morally right and good if and to the extent that they add to human happiness or diminish human unhappiness. And—or, perhaps, therefore—it also tells us that the best action a person can perform is that which of all the possible actions open to him is the one which makes the greatest positive difference to human happiness. Moreover, as everyone will also remember, utilitarianism further tries to tell us, perhaps intending it as a corollary of (...) that first, main claim, that the motive for an action has nothing to do with its moral rightness or goodness. But even if, as utilitarians, we accepted the dubious corollary, it would not follow, as many have thought, that utilitarians have no moral interest in motives. For unless, absurdly, a utilitarian believed either that there was never more than a fortuitous connection between on the one hand what we intended to do and on the other what we did and the consequences of what we did, or that, if there were such connections, we could not know of them, he must believe, as a moralist, that the best motive a person can have for performing an action is likely to be the desire to produce the happiest result. Indeed, utilitarians ought to be morally committed, it would seem, to trying to find out as much as they can about the consequences of our actions, e.g. what connections exist, if any, between how we raise children and what sort of adults they grow up to be.

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)
