Conciliatory Views and Higher-Order Disagreements, R&Red to a generalist journal
Abstract: Conciliatory views on disagreement say, roughly, that it’s rational for you to become less confident in your well-reasoned opinion in case you find out that an epistemic peer holds the opposite opinion. These views are intuitively appealing, but there are also well-known worries about their behavior in scenarios involving what we might call higher-order disagreements, including disagreements over conciliatory views themselves and disagreement over the peerhood of the person you’re in disagreement with. This paper does two things. First, it explains how the core idea behind conciliatory views can be expressed in a defeasible logic framework. The result is a formal model that’s particularly useful for understanding the behavior of conciliatory views in cases involving higher-order disagreements. And second, the paper uses this model to resolve three paradoxes that are said to arise when conciliationism attempts to deal with disagreements over epistemic peerhood.
Deontic Reasoning on the Basis of Consistency Considerations, with Christian Straßer and Joke Meheus, R&R from a specialist journal
Abstract: Deontic conflicts pose an important challenge to deontic logicians. The standard account, standard deontic logic, is not apt for addressing this challenge since it trivializes conflicts. Two main stratagems for gaining conflict-tolerance have been proposed: to weaken standard deontic logic in various ways, and to contextualize its reign to consistent subsets of the premise set. The latter began with the work of van Fraassen and has been further developed by Horty. In this paper we characterize this second approach in general terms. We also study three basic ways to contextualizes standard deontic logic and supplement each of these with a dynamic proof theory in the framework of adaptive logics.
