This paper sketches a theory of the reason-giving force of well-being that allows us to reconcile our intuitions about two of the most recalcitrant problem cases in population ethics: Jan Narveson’s Procreation Asymmetry and Derek Parfit’s Non-Identity Problem. I show that what has prevented philosophers from developing a theory that gives a satisfactory account of both these problems is their tacit commitment to a teleological conception of well-being, as something to be ‘promoted’. Replacing this picture with one according to which our reasons to confer well-being on people are conditional on their existence allows me to do better. It also enables us to understand some of the deep structural parallels between seemingly disparate normative phenomena such as procreating and promising. The resulting theory charts a middle way between the familiar dichotomy of narrow personaffecting theories and totalist or wide-person affecting theories in population ethics. 1. The Procreation Asymmetry Many of us hold pre-theoretical views about the morality of procreation that are, in an important sense, asymmetrical. Suppose you can foresee that a child you could create would live a life so full of uncompensated suffering as to be not worth living.1 Most would agree that – exceptional circumstances aside – it would constitute a serious moral wrong to bring this child into existence. That is, given a choice between Nobody: Create no new life and Misery: Create person A, with a life that is not worth living we believe that there is strong moral reason to choose Nobody over Misery. 1 More precisely, imagine that such a child would have a life that is, in Derek Parfit’s phrase, “worth not living”, since its life would be worse than a life spent in a permanent coma (which would also be not worth living). For stylistic reasons, I will continue to use the former locution.
