Personal information

Hannes Leitgeb is Chair of Logic and Philosophy of Language, founder and co-director of the Munich Center for Mathematical Philosophy (MCMP), and Dean of Research at the Faculty of Philosophy, Philosophy of Science and Religious Studies. He researches and teaches on questions in logic, philosophy of logic and mathematics, epistemology, philosophy of language, general philosophy of science, the history of logical empiricism and philosophy of the cognitive sciences. His current research interests include the logic of inductive reasons, the analysis of neural networks by means of inductive logic, logical inferentialism, logicism in the philosophy of mathematics, the meaning of "merely expressive" linguistic devices, and a metaphilosophical understanding of philosophy as rational reconstruction.
