Defeasible Commitment and Prima Facie Obligation

  • Fred Feldman
Part of the Philosophical Studies Series in Philosophy book series (PSSP, volume 35)

Abstract

The iffy oughts of ordinary language are a logically heterogeneous group. As we have seen, a given sentence with ‘if’ and ‘ought’ may express any of several different sorts of proposition. As I see it, this fact is responsible for one of the most serious defects in the literature concerning iffy oughts. We frequently find cases in which one writer, focussing on one sort of iffy ought, proposes an analysis. He claims to have given an account of “conditional obligation”. A critic, appealing to examples of another sort of iffy ought, claims thereby to have shown the analysis defective. Obviously, however, the criticism misfires, since the two writers are talking about different classes of sentences.
