Professor Susanne Bobzien
Professor of Philosophy, Em., University of Oxford
MA, DPhil, FBA
Quondam Fellow since 2023
My present research projects include a monograph on the history of hypothetical syllogistic, a study on the logic of vagueness and higher-order vagueness, as well as further explorations of Stoic logic and of its relations to Frege and 19th‒20th century logic. I also retain an interest in determinism, freedom, and responsibility and in MAP.
