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 among logic, situation theory, and situation semantics. Several papers appear here for the first time.
Some of the papers here are great, much better than S&A. The connections between situation semantics and things like cognitive offloading in embodied cognition are apparent. Also addresses the connection between underarticulation and ineffability. Unarticulated non constituents are determinant in the content being what it is, they are sensitive to shifts in the index, but they are not part of the content (even the purely externally determined content). Barwises example: “This needs salt”: request or statement of fact? Anyway, lots to chew on, very well written too
