Mild Contraction: Evaluating Loss of Information Due to Loss of Belief

Isaac Levi


This book is a continuation of Isaac Levi’s work on formal epistemology, focusing on the problem of contraction. It argues that the problem of how to contract is essential both to an account of justified or legitimate belief change, and to modal judgment conditional on a supposition. It presents a formal characterization of mild contraction, which is similar to what Pagnucco and Rott called “severe withdrawal”. This difference in terminology reflects a difference in philosophical perspective that is explained by the author.

Keywords: belief, mild contraction, epistemology, belief change, judgment
