Jonathan Seim

DIID-Team, Philosophy

Jonathan Seim is a research associate at DIID, responsible for the coordination of the institute. He is also a research associate in the Digital Ethics project at the Center for Advanced Internet Studies (CAIS). His position is financed by project funds from Stiftung Mercator. Previously, he studied political science and philosophy at HHU-Düsseldorf and at the University of the West of Scotland. His research focuses on moral philosophy and political philosophy, especially the theory of democracy. His dissertation in philosophy deals with democratic participation rights in citizen participation processes. Even though a correct distribution of participation rights is of fundamental importance for the legitimacy of the procedures, this question is neither sufficiently addressed in politics nor in science. The aim of the dissertation project is to develop criteria for the allocation of participation rights in consultative citizen participation procedures and practical recommendations for action.

In the context of DIID, his interest is focused on the legitimacy conditions of online participation.
