Abstract

Logic appears to be normative for rational belief. The thesis of the normativity of logic holds that indeed logic has such a normative status. Gilbert Harman has questioned it, thereby giving rise to what has been called “Harman's skeptical challenge”. MacFarlane has clarified that in order to answer this challenge and support the normativity of logic, one needs a “bridge principle” that appropriately connects logical entailments and norms for belief, as well as relevant desiderata for the evaluation of candidate bridge principles. Steinberger has identified a list of desiderata, on the basis of which he has proposed his own bridge principle and shown the inadequacy of previous proposals. This paper argues that Steinberger's list is in need of revision and his principle is unsatisfactory, and then puts forward a revised list of desiderata and a new bridge principle in support of the normativity of logic.
