Act Utilitarianisms divide into Total and Average versions. Total versions seem to imply Parfit’s “Repugnant Conclusion”. Average versions are proposed in part to avoid the Repugnant Conclusion, but these are subject to “Mere Addition” arguments as detailed by Hudson in “The Diminishing Marginal Value of Happy People”. Thus, various intermediate versions of utilitarianism, such as the one investigated by Hurka in “Value and Population Size”, take on interest. But Hudson argues that such compromise theories are subject to the mere addition (...) arguments, and are therefore no improvement over Average Utilitarianism. I disagree: some such compromise solutions escape Hudson’s Mere Addition arguments. (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)

First published in 1903, this volume revolutionized philosophy and forever altered the direction of ethical studies. A philosopher’s philosopher, G. E. Moore was the idol of the Bloomsbury group, and Lytton Strachey declared that Principia Ethica marked the rebirth of the Age of Reason. This work clarifies some of moral philosophy’s most common confusions and redefines the science’s terminology. Six chapters explore: the subject matter of ethics, naturalistic ethics, hedonism, metaphysical ethics, ethics in relation to conduct, and the ideal. Moore's (...) simplicity of style and precise use of everyday language exercised an enormous influence on the development of analytic philosophy, and they contribute to the continuing resonance of his compelling arguments.

"Well-being," "welfare," "utility," and "quality of life," all closely related concepts, are at the center of morality, politics, law, and economics. Griffin's book, while primarily a volume of moral philosophy, is relevant to all of these subjects. Griffin offers answers to three central questions about well-being: what is the best way to understand it, can it be measured, and where should it fit in moral and political thought. With its breadth of investigation and depth of insight, this work holds significance (...) for philosophers as well as for those interested in political and economic theory and jurisprudence.

Thomas Hurka has recently proposed a utilitarian theory which would effect a compromise between Average and Total utilitarianism, the better to deal with issues in population ethics. This Compromise theory would incorporate the principle that the value which an extra happy person contributes to a possible world is a decreasing function of the total population of that world: that happy people are of diminishing marginal value. In spite of its initial plausibility I argue against this principle. I show that the (...) Compromise theory is actually no improvement over the two original versions of utilitarianism; in particular, it is subject to almost all the objections which are fatal to Average utilitarianism, and more besides. And I attempt to dispell the appearance that intuition supports the Compromise theory as against Total utilitarianism, by arguing that the latter's Repugnant Conclusion, when properly understood, is not intuitively unacceptable. Total utilitarianism remains a plausible ethical theory, while both the Average and the Compromise theories should be definitely rejected. (shrink)

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)

A search is under way for a theory that can accommodate our intuitions in population axiology. The object of this search has proved elusive. This is not surprising since, as we shall see, any welfarist axiology that satisfies three reasonable conditions implies at least one of three counter-intuitive conclusions. I shall start by pointing out the failures in three recent attempts to construct an acceptable population axiology. I shall then present an impossibility theorem and conclude with a short discussion of (...) how it might be extended to pluralist axiologies, that is, axiologies that take more values than welfare into account.

Just because an angel is better than a stone, it does not follow that two angels are better than one angel and one stone. So said Aquinas (Summa contra Gentiles III, 71), and the sentiment was echoed by Leibniz. In section 118 of the Theodicy he wrote: "No substance is either absolutely precious or absolutely contemptible in the sight of God. It is certain that God attaches more importance to a man than to a lion, but I do not know (...) that we can bc sure that he prefers one man to an entire species of lions." Even Kant was bitten by this bug. In one of his pre-Critical works he was moved to say, à propos of lice, that even though they “may in our eyes be as worthless as you like, nevertheless it is of more consequence to Nature to conserve this species as a whole than to conserve a small number of members of a superior species." In these passages Aquinas, Leibniz, and Kant gave expression to a distinctive and interesting view about the value of animal species and animal populations. At its simplest, this is the view that there is a special value in the existence of animal species or in the existence of a wide variety of different animal species. But the view also goes deeper than this. An animal species, after all, is nothing over and above the individual animals which make it up, and the value which it contributes to the world must therefore be some function of the values contributed by those individual animals. At the deepest level, what the view expressed by Aquinas, Leibniz, and Kant holds is that the value which an individual animal contributes to thc world is not constant but varies with the number..

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

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)

Franz Brentano developed an original theory of intrinsic value which he attempted to base on his philosophical psychology. Roderick Chisholm presents here a critical exposition of this theory and its place in Brentano's general philosophical system. He gives a detailed account of Brentano's ontology, showing how Brentano tried to secure objectivity for ethics not through a theory of practical reason, but through his theory of the intentional objects of emotions and desires. Professor Chisholm goes on to develop certain suggestions about (...) intrinsic value made by Brentano and his students, and discusses their relevance to theodicy and the problem of evil. Brentano, as the teacher of Husserl, Meinong, Twardowski, and others, stands at the origin of the phenomenological tradition and of the Polish school of philosophy that developed after World War I. He has also had considerable influence on Anglo-American philosophy. This book will interest those concerned with the origins of phenomenological value theory and more generally with the connections between ethics and philosophical psychology. (shrink)

In a series of articles on population theory, culminating in his 1984 b00k Reasons and Persons, Dcrck Pariit presented dilemmas for utilitarian and conscqucntialist moral theories.] ParHt’s work has led to rcncwcd interest in thc theory of optimal population. More generally, Pariit is searching for a general theory of bcncHcencc—"Theory X"——that also will covcr population comparisons. Theory X corresponds to Kenneth Arrow’s notion of a social welfare function—both attempt t0 provide 21 generic formula or algorithm for ranking social outcomes on (...) the basis of their characteristics.
