ABSTRACT

In his Reasons and Persons (1984) Derek Parfit famously canvassed what he called ‘The Repugnant Conclusion’: ‘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’ (p. 388).
