How Common is Peer Disagreement? On Self‐Trust and Rational Symmetry

Abstract

In this paper I offer an argument for a view about the epistemology of peer disagreement, which I call the “Rational Symmetry View”. I argue that this view follows from a natural (if controversial) conception of the epistemology of testimony, together with a basic entitlement to trust our own faculties for belief formation. I then discuss some objections to this view, focusing on its relationship to other well‐known views in the literature. The upshot of this discussion is that, if the Rational Symmetry View is correct, much of the action in the epistemology of disagreement relates—not to how one should treat those one regards as an “epistemic peer” in the sense popular in that literature—but rather to who one should treat as such.
