This is the second part of a two-volume anthology which concentrates on philosophical questions related to actions performed by single individuals or groups. The focus of this volume is the philosophy and logic of actions performed by several individuals or groups of individuals. The two volumes can be read independently of each other. The books should be of interest to researchers and students in philosophy and artificial intelligence and also to theoretically-minded researchers in psychology, and, where Volume Two is concerned, many social sciences including social psychology, organization research and economics as well as in jurisprudence. They should also be suitable for graduate seminars in philosophy and theoretical artificial intelligence.
