In this essay I argue that even though egalitarianism and prioritarianism are different theories of social welfare, they can use the same social welfare measures. I present six different arguments for this thesis. The first argument is that conceptual connections between egalitarianism and prioritarianism ensure that any measure that works for either theory works for both. The second argument is that conditions necessary and sufficient to identify egalitarian and prioritarian measures, respectively, are equivalent. The third argument is that both egalitarianism (...) and prioritarianism can use two standard measures, typically proposed for only one theory. The fourth to sixth arguments contend that four properties that have been proposed as distinctive of either egalitarian or prioritarian measures cannot distinguish between them. I conclude that any egalitarian measure is also a prioritarian measure, and vice versa. (shrink)

Principles of sufficiency are widely discussed in debates about distributive ethics. However, critics have argued that sufficiency principles are vulnerable to important objections. This paper seeks to clarify the main claims of sufficiency principles and to examine whether they have something distinctive and plausible to offer. The paper argues that sufficiency principles must claim that we have weighty reasons to secure enough and that once enough is secured the nature of our reasons to secure further benefits shifts. Having characterized sufficientarianism (...) in this way, the paper shows that the main objections to the view can be avoided; that we can examine the plausibility of sufficiency principles by appealing to certain reasons that support a shift; and that we should be optimistic about the prospects for sufficientarianism because many of our strongest reasons seem to be of this sort. This shift, I claim, is the overlooked grain of truth in sufficientarianism. (shrink)

In a recent article, Michael Otsuka and Alex Voorhoeve argue that prioritarianism fails to account for the shift in moral significance in gains to individuals in interpersonal as compared to intrapersonal cases. In this article, I show that the priority view escapes this objection but in a way that deprives it of (some of) its anti-egalitarian stance. Despite Otsuka and Voorhoeve, prioritarianism, rightly understood, provides consistent and attractive recommendations in both single- and multi-person cases. Yet prioritarians, the article goes on (...) to show, cannot do so while availing themselves of the leveling down objection (LDO) to egalitarianism. They may not do so because similarly to egalitarianism, prioritarianism also must reject the principle of personal good. That is, egalitarians and prioritarians may sometime recommend certain actions and outcomes even when these are better for no one. Prioritarians may survive the Otsuka–Voorhoeve critique, but to do so they must abandon their anti-egalitarian stance (or at the very least, the LDO). (shrink)
