A non-identity dilemma for person-affecting views

Elliott Thornley (Global Priorities Institute, University of Oxford)

GPI Working Paper No. 6-2024

Person-affecting views state that (in cases where all else is equal) we’re permitted but not required to create people who would enjoy good lives. In this paper, I present an argument against every possible variety of person-affecting view. The argument is a dilemma over trilemmas. Narrow person-affecting views imply a trilemma in a case that I call ‘Expanded Non-Identity.’ Wide person-affecting views imply a trilemma in a case that I call ‘Two-Shot Non-Identity.’ One plausible practical upshot of my argument is as follows: we individuals and our governments should be doing more to reduce the risk of human extinction this century.

This paper highlights the existence of an argument from intuitively plausible axiological principles to the striking conclusion that in comparing different populations, there exists some depth of suffering that cannot be compensated for by any measure of well-being. In addition to a number of structural principles, the argument relies on two key premises. The first is the contrary of the so-called Reverse Repugnant Conclusion…

It’s a philosophy and a social movement that is gaining considerable steam in the philanthropic world. For example,…

How to neglect the long term – Hayden Wilkinson (Global Priorities Institute, University of Oxford)

Consider longtermism: the view that, at least in some of the most important decisions facing agents today, which options are morally best is determined by which are best for the long-term future. Various critics have argued that longtermism is false—indeed, that it is obviously false, and that we can reject it on normative grounds without close consideration of certain descriptive facts. In effect, it is argued, longtermism would be false even if real-world agents had promising means…
