A critique of inferences from “is” to “ought” plays a central role in Elqayam & Evans' (E&E's) defense of descriptivism. However, the reflective equilibrium strategy described by Goodman and embraced by Rawls, Cohen, and many others poses an important challenge to that critique. Dual-system theories may help respond to that challenge.
