The Many Faces of Closure and Introspection. An Interactive Perspective.

This paper supersedes Interactive Models of Closure and Computation

Published in the Journal of Philosophical Logic. 42(1): 91–124.

Abstract. In this paper I present a more refined analysis of the principles of deductive closure and positive introspection. This analysis uses the expressive resources of logics for different types of group knowledge, and discriminates between aspects of closure and computation that are often conflated. The resulting model also yields a more fine-grained distinction between implicit and explicit knowledge, and places Hintikka’s original argument for positive introspection in a new perspective.
