Jeremy Seligman is a philosopher and logician, applying ideas from mathematics and logic to philosophical problems, with current focus on social reasoning. He also has an active interest in the history of logical thought in China. Dr. Seligman’s research involves the application of ideas from logic and mathematics to philosophically interesting topics. His early career focus was on Situation Theory - the attempt to provide a mathematically precise account of contextual information and reasoning. From that Dr. Seligman progressed to Hybrid Logic, which has since become a mainstream tool for work in applied philosophical logic. More recently, he has been working on the models of reasoning in social situations in a project with the general title “Logic in the Community”, and on applications of modern techniques to modeling the theories of reasoning in ancient China.
