How to resolve doxastic disagreement

  • Peter Brössel

How should an agent revise her epistemic state in the light of doxastic disagreement? The problems associated with answering this question arise under the assumption that an agent’s epistemic state is best represented by her degree of belief function alone. We argue that for modeling cases of doxastic disagreement an agent’s epistemic state is best represented by her confirmation commitments and the evidence available to her. Finally, we argue that given this position it is possible to provide an adequate answer to the question of how to rationally revise one’s epistemic state in the light of disagreement.

Early versions of this paper have been presented at conferences, respectively workshops, in Bochum (Recent Debates in Epistemology), Lund (CPH LU Workshop on Social Epistemology), and Salzburg (SOPhia 2013) and at the Tilburg Center for Philosophy of Science. We thank the audience for their insightful comments on various versions of the paper. We are also grateful to the MCMP (Munich Center for Mathematical Philosophy) reading-group on social epistemology for fruitful discussion on Jehle and Fitelson’s paper. Special thanks go to Lorenzo Casini, Stephan Hartmann, Albert Newen, Carlo Proietti, Gerhard Schurz, Jan Sprenger, and Frank Zenker. We would also like to thank two anonymous referees for very helpful commentaries on an earlier version of this paper. Anna-Maria A. Eder’s research on this paper was partly funded by a fellowship (Stipendium nach dem Landesgraduiertenförderungsgesetz) sponsored by the State of Baden-Württemberg (Germany). Peter Brössel’s research was supported by a Visiting Fellowship by the Tilburg Center for Philosophy of Science.
