Describing rationality

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.
