Former Fellow

Elisabeth Theresia Widmer

Postdoctoral Researcher at the London School of Economics

In cooperation with Prof. Dr. Rainer Forst

Duration of stay: April – September 2025

Dr. Elisabeth Theresia Widmer is a postdoctoral researcher, specializing in the theoretical frameworks that have shaped what is colloquially called “social democracy” (though she prefers the term communitarian republicanism). Her primary research interest lies in what she calls the “left-Kantian” tradition of the nineteenth and twentieth centuries. This current is heavily influenced by Kant’s philosophy but replaces his individualist notion of freedom with a communitarian concept of freedom inspired by Marx. Although her work focuses on historical authors, she engages with them in dialogue with contemporary political theorists, particularly neo-Marxists (such as Gerald A. Cohen), neo-Republicans (such as Philip Pettit), and Critical Theorists (such as Rainer Forst).
