Epistemic logic is the study of the principles of inference and the formal semantics of knowledge, belief, and other epistemic notions. This entry discusses the literature in a number of areas therein, including the traditions of treating knowledge and belief with familiar alethic modal logic and possible-world semantics, and of treating these notions in a more dynamic setting that finds its historical roots in belief revision theory (i.e., the formalization of the principles for rational belief updating). This article will also cover special topics, such as the semantics of epistemic modals (that is, epistemic uses of “must,” “might,” “possibly,” etc.) and the semantics of epistemic conditionals (arguably, all indicative “ifs”). We conclude with an overview of important formal (and semiformal) epistemic paradoxes—the most familiar and fundamental epistemic puzzles that demand a formal (or semiformal) treatment.
