Abstract

This paper discusses a challenge to normative ethics motivated by experimental philosophy. Experimental philosophers object to the perceived “armchair” or a priori nature of philosophy, claiming it should rather be empirical or naturalistic. The paper investigates the application of this claim to normative ethics. Dubbing the application of the experimental philosophers’ contention to normative ethics “the Armchair Claim,” I distinguish descriptive and normative versions of this challenge, and consider their merits as comments on the method of normative ethics (descriptive versions), and as comments on how normative ethics should be done (normative versions). Characterizing normative ethics as essentially involving the use of the method of reflective equilibrium, I show how the versions of the Armchair Claim that I distinguish either misconstrue normative ethics, or are committed to metaethical views that are controversial. To bring home the latter point, I contrast two meta-ethical positions, and show how, on one such view, naturalism, the descriptive version could be correct, whereas on another, intuitionism, it would be false. The normative version, in turn, is consistent with naturalism, but begs the question against the intuitionist since she argues that normative ethics cannot be empirical. The upshot is that a conclusive assessment of the Armchair Claim will have to await the resolution of disputed issues in meta-ethics. However, normative ethicists can get on with their work since reflective equilibrium is unaffected by such debates.
