Why is someone enduringly prized as a philosopher? To answer this question, this historical case study examines the intersecting careers of John Rawls and R. M. Hare. It looks at their writings, a complex chain of disagreements, the argumentative dimension. The essay moreover explores the clash of differing temperaments. Finally, themes in addition to ratiocination and personality are factored in: the leanings of the institutions that control access to intellectual endeavor; the public square—politics widely conceived—into which the two men were (...) thrown; and the cultural rivalry between England and America after World War Two.
