Describing rationality

Abstract

This critical study of John Broome’s Rationality Through Reasoning (i) raises some questions about the various requirements of rationality Broome formulates, pointing out some apparent gaps and counterexamples; (ii) proposes a general description of rationality that is broadly consistent with Broome’s requirements while providing them with a unifying justification, filling the gaps, and removing the counterexamples; and (iii) presents two objections to the book’s broader argument concerning the nature and importance of reasoning.
