Abstract

This paper discusses responses to Disagreement, Deference, and Rational Commitment from Bogardus and Burton, Thurow, and Kvanvig. Each of these responses objects to the rationalist account of “partisan justification” defended in the book. After explaining partisan justification and its significance, I first take up Bogardus and Burton’s argument for a more restrictive account of partisan justification which says that partisan justification requires certainty. I argue that this account yields implausible discontinuities in the verdicts given to nearly identical cases. Next, I consider Thurow’s suggestion that perceptual evidence can provide partisan justification without supporting rational insight. I explain why insight plays a crucial role in cases where perceptual beliefs enjoy partisan justification. Finally, I address Kvanvig’s objection that my account of partisan justification applies only to highly reflective agents. I argue that a subject’s actual reflectiveness does not bear on the sense of justification principally at issue in the disagreement literature.
