Exploring the metaphysics of deep disagreements, Ranalli identifies several essential features shared by all such disputes. These very features constitute a set of adequacy conditions that any satisfactory theory of deep disagreements must meet. The paper explains how Coliva’s Wittgensteinian hinge theory can satisfy Ranalli’s persistence desideratum. According to this condition, any appropriate theory must explain why deep disagreements tend to be persistent and thus unresolved without presupposing that they are rationally irresolvable. First, the work critically discusses how Coliva utilizes (...) her proposed view to account for this desideratum. Second, the paper points out that Coliva’s response is partly problematic because of Ranalli’s definition of deep disagreements for Wittgensteinian hinge theories, which over-generates instances of genuine deep disagreements. Third, the work argues that Coliva’s theory can satisfy Ranalli’s persistence desideratum by resolving a deep disagreement between an anti-vaccination advocate and a proponent of vaccination using an expanded version of Pritchard’s side-on approach. Finally, the paper critically engages with Coliva on the solvability of deep disagreements. (shrink)
