Mere Addition Paradox

A principal aim of the branch of ethics called ‘population theory’ or ‘population ethics’ is to find a plausible welfarist axiology, capable of comparing total outcomes with respect to value. This has proved an exceedingly difficult task. In this paper I shall state and discuss two ‘trilemmas’, or choices between three unappealing alternatives, which the population ethicist must face. The first trilemma is not new. It originates with Derek Parfit's well-known ‘Mere Addition Paradox’, and was first explicitly stated by Yew-Kwang Ng. I shall argue that one horn of this trilemma is less unattractive than Parfit and others have claimed. The second trilemma, which is a kind of mirror image of the first, appears hitherto to have gone unnoticed. Apart from attempting to resolve the two trilemmas, I shall suggest certain features which I believe a plausible welfarist axiology should possess. The details of this projected axiology will, however, be left open.

Better Than

In Inequality, Larry Temkin attacks ‘The Slogan’: ‘One Situation cannot be [morally] worse (or better) than another in any respect if there is no one for whom it is worse (or better) in any respect.’ Temkin notes that the Slogan has great intuitive appeal. It underlies, for example, the conviction that it is irrational to prefer a Pareto-inferior outcome; the transition from egalitarianism to the difference principle; Robert Nozick's Wilt Chamberlain example; defense of appropriation under the Lockean proviso; and Derek Parfit's Mere Addition Paradox. As an egalitarian, Temkin's main concern with the Slogan is the support it gives to the ‘leveling down objection’ to egalitarianism: the egalitarian finds it to be in some respect an improvement that the better-off are leveled down to the position of the worse-off, without any gain to the worse-off. The Slogan condemns this: leveling down cannot be better in any respect, since there is no one for whom it is better in any respect.

Mere Addition Paradox

The main claim of this chapter is that multidimensional consequentialists have reason to reject some of the key premises of Parfit’s Mere Addition Paradox as well as Arrhenius’s sixth impossibility theorem. The latter is the most general and far-reaching impossibility theorem in the literature on population ethics. The chapter shows that multidimensional consequentialists can reasonably maintain that the mere addition of people who have lives worth living is not always entirely right. To add what Parfit calls “extra people” is right with respect to one moral aspect (the size of the population) but wrong with respect to another (the average quality of life).

Mere Addition Paradox

In this paper, I describe three structural issues population ethics raises for any form of consequentialism that embraces what we can call the basic maximizing idea, the idea that it makes things better, in a morally relevant sense, to make things better for people. What we say about those structural issues will in turn determine what we say about some of the most challenging problems of population ethics. I explore a handful of our options here, discarding some and leaving others on the table. My primary focus is on how those options propose to resolve the mere addition paradox, a population problem that is important in its own right and whose resolution is defining for what we will want to say about many other population problems.
