"The Logic of Epistemic Reasons. An Axiomatic Account "

Résumé : The talk will argue for a system of axioms that is meant to capture the logic of normative reasons for belief. The system concerns two kinds of reason-for relations, an identity criterion for reasons, an aggregation function for reasons, and a function for the revision of belief by reasons. The resulting theory avoids problems that have been ascribed to the additive aggregation of reasons, it entails that reasons conform to a vector structure, it builds a bridge between the philosophical theory of reasons and Bayesian formal epistemology, and it might have some applications in explainable AI.
