Logical Dynamics of Social Communication

ABSTRACT: Inspired by the development of Dynamic Epistemic Logics in the last two decades, dynamic changes brought about by acts of commanding, suggesting, promising, asserting, conceding, and so on are studied in logical terms, and various dynamic logics are developed. I will review the development of dynamified deontic logics that deal with acts of commanding and promising in detail, and show how logical methods can be utilized to analyze dynamics of social communication. I will also mention one special feature of dynamified deontic logics: it enables us to accommodate conflicts of obligations that arise in everyday situations without triggering deontic explosion.
