Situation theory and situation semantics are recent approaches to language and information, approaches first formulated by Jon Barwise and John Perry in Situations and Attitudes (1983). The present volume collects some of Barwise's papers written since then, those directly concerned with relations between logic, situation theory, and situation semantics. Several appears appear here for the first time.

Jon Barwise (1942–2000) was director of the Symbolic Systems
Program and professor of philosophy at Stanford University and a
researcher at CSLI.
