Subjective Rationality and the Reasoning Argument

My main aim in this paper is to show that Kolodny’s intriguing argument against wide-scopism – ‘the Reasoning Argument’ – fails. A proper evaluation of the Reasoning Argument requires drawing two significant distinctions, one between thin and thick rational transitions and the other between bare-bones wide-scopism (and narrow-scopism) and embellished wide-scopism (and narrow-scopism). The Reasoning Argument is intended by Kolodny both as an argument against bare-bones wide-scopism and as an argument against embellished wide-scopism. I argue that despite its formidable virtue of demonstrating the need for an account of thick subjective rationality, the Reasoning Argument works neither against bare-bones wide-scopism nor against embellished wide-scopism.
