Abstract

Prioritarianism is a distinctive moral view. Outcomes are ranked according to the sum of concavely transformed well-being numbers—by contrast with utilitarianism, which simply adds up well-being. Thus, unlike utilitarians, prioritarians give extra moral weight to the well-being of the worse off. Unlike egalitarians, prioritarians endorse an axiom of person-separability: the ranking of outcomes is independent of the well-being levels of unaffected individuals. Unlike sufficientists, who give no priority to the worse-off if their well-being exceeds a “sufficiency” threshold, prioritarians always favor the worse-off in conflicts with those at higher well-being levels. Derek Parfit is prioritarianism’s most famous proponent. We have also defended prioritarianism. Not everyone is persuaded. Prioritarianism has been vigorously criticized, from a variety of perspectives, most visibly by John Broome, Campbell Brown, Lara Buchak, Roger Crisp, Hilary Greaves, David McCarthy, Michael Otsuka, Ingmar Persson, Shlomi Segall, Larry Temkin, and Alex Voorhoeve. In this Article, we answer the critics.

Keywords: prioritarianism, utilitarianism, egalitarianism, sufficientism, Parfit
