This volume presents mathematical game theory as an interface between logic and philosophy. It provides a discussion of various aspects of this interaction, covering new technical results and examining the philosophical insights that these have yielded. Organized in four sections it offers a balanced mix of papers dedicated to the major trends in the field: the dialogical approach to logic, Hintikka-style game-theoretic semantics, game-theoretic models of various domains (including computation and natural language) and logical analyses of game-theoretic situations. This volume will be of interest to any philosopher concerned with logic and language. It is also relevant to the work of argumentation theorists, linguists, economists, computer scientists and all those concerned with the foundational aspects of these disciplines.
