Abstract

Obligation describing language is hooked up with preference, a relation of what-is-better-than-what. But ordinary situations underdetermine such relations of what-is-better-than-what. Even so, there are plainly true sentences describing our obligations in those situations. This mismatch is trouble-making and getting out of the trouble requires either giving up the easy link between “ought” and preference or re-thinking the kind of things preferences can be.
