What Can a Constructivist Say About Animal Ethics — Or Any Other Normative Question, for That Matter?

Abstract

In Fellow Creatures, Christine Korsgaard claims that human beings ought to treat all sentient animals as ends in themselves. However, in this article, I argue that Korgaard's method goes beyond what a coherent constructivist conception allows, and I claim that we should therefore adopt a Humean rather than a Kantian version of constructivism. I believe that such a conception permits us to hold substantial ethical positions about non-human animals without having to compromise our ontological commitments.
