Logic and Agency
Logic started as the exact study of reasoning by human actors, and over time also, by computing machines. Increasingly, the tools developed in this study are starting to cover a much wider range of informational actions, including observation and communication, and interactive patterns of rational agency depending on these. This project is devoted to developing the logic of information-driven social agency, bridging the gap from individual to social information behavior, and studying the role of constantly emerging structured social entities such as groups and networks. The resulting questions lie at the intersection of logic, philosophy, computer science, and the social sciences.
