Steadfast Views of Disagreement are Incoherent

Abstract

Abstract In this paper, I argue that Steadfast Views of peer disagreement - a family of views according to which standing firm in the face of peer disagreement can be rationally permissible are incoherent. First, I articulate two constraints that any Steadfast Views of disagreement should endorse: (i) Steadfastness's Core (ii) The Deference Principle. I show that (i) and (ii) are inconsistent: they cannot both be true. My argument, briefly put, is that one cannot rationally treat one's peer's opinion as unconditionally relevant to a hypothesis, H, but conditional on the supposition of a disagreement, irrelevant to H. Because Steadfast Views endorse a set of mutually inconsistent propositions, I conclude that Steadfast Views are incoherent
