Stig Kanger (1924-1988) made important contributions to logic and formal philosophy. Kanger's most original achievements were in the areas of general proof theory, the semantics of modal and deontic logic, and the logical analysis of the concept of rights. But he contributed significantly to action theory, preference logic and the theory of measurement as well. This is the second of two volumes dedicated to the work of Stig Kanger. The first volume is a complete collection of Kanger's philosophical papers. The present volume contains critical essays on the various aspects of Kanger's work as well as some biographical sketches. Lennart Åqvist, Jan Berg, Brian Chellas, Anatoli Degtyarev, Lars Gustafsson, Sören Halldén, Kaj Børge Hansen, Sven Ove Hansson, Risto Hilpinen, Jaakko Hintikka, Ghita Holmström-Hintikka, Lars Lindahl, Sten Lindström, Ingmar Pörn, Dag Prawitz, Wlodek Rabinowicz, Krister Segerberg, Amartya Sen, Sören Stenlund, Göran Sundholm, and Andrei Voronkov have contributed to this volume.
