Constructing Moral Equality

Moral equality—the idea that ‘we’ all have equal moral worth, our interests ought to count for the same, and we possess the same bundle of basic rights—is one of the most central principles of liberal thought, being regularly drawn on as a presupposition of moral and political inquiry. Perhaps because it is so often relied on as a presupposition, however, moral equality is more often assumed than argued for. When moral equality is argued for, the most common tactic is to appeal to some inherent property. As is well established, however, such property-based defenses of moral equality face two significant challenges: the problem of exclusion and the problem of inequality. In light of these challenges, in this article I put forward a new, revisionist account of moral equality. Taking inspiration from recent work in the social metaphysics of human kinds, I argue that moral equality ought to be seen as a component of a status that we confer on one another, rather than (grounded in) a property inherent in certain individuals. Conceiving of moral equality this way, I argue, side-steps both the problem of exclusion and the problem of natural equality.
