A study of how federal district court judges think about the sentencing of white-collar criminals, based on extensive interviews. Findings reveal a discrepancy between agreed-upon principles and actual outcomes. 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 papers appear here for the first time.
