Rainer Forst

Rainer Forst is Professor of Political Theory and Philosophy at Goethe University Frankfurt, where he holds positions in both the Institute of Political Science and the Institute of Philosophy. He serves as Director of the Research Center for Normative Orders, Co-speaker of the cluster initiative "ConTrust – Trust in Conflict," Spokesperson of the Leibniz Prize Research Group "Transnational Justice," and Deputy Spokesperson of the Coordinating Institute Frankfurt at the Research Institute for Social Cohesion. Additionally, he is a Permanent Fellow at the Research College for Human Sciences Bad Homburg, Director of the Justitia Center for Advanced Studies, and Head of the Master's program in Political Theory. Since 2017, he has also been a Research Professor of Political Theory at the Social Science Research Center (WZB) in Berlin.

Forst received his education studying philosophy, political science, and American studies in Frankfurt/Main, New York, and at Harvard University. His academic journey includes:

• Ph.D. under Jürgen Habermas with thesis "Contexts of Justice: Political Philosophy Beyond Liberalism and Communitarianism" (1993)
• Habilitation in 2003 with "Tolerance in Conflict: History, Content, and Present of a Controversial Concept"

Professor Forst's research focuses on foundational questions of political philosophy and critical theory. His work centers on justice theory, democracy, toleration, normative orders, and social cohesion. He has developed a distinctive approach he terms "critical constructivism," which builds on Kantian philosophy while engaging with the Frankfurt School tradition of critical theory. His research examines how justification processes form the basis of legitimate political orders and how concepts like solidarity and tolerance function within democratic societies. Forst's work is notable for its systematic integration of historical analysis with normative theory, creating frameworks for understanding contemporary political challenges through the lens of philosophical tradition.

His recent publications reveal a growing focus on democratic regression, trust in conflictual societies, and the philosophical foundations of social cohesion. Forst has increasingly addressed the dual crises of democracy - both the political-normative justification crisis and the global structural crisis. His work connects Kantian philosophy with contemporary democratic theory, exploring concepts like the "noumenal republic" as frameworks for understanding justice and legitimacy in complex societies. A consistent thread throughout his scholarship is the examination of how power relations intersect with normative claims in political justification processes.

Professor Forst has received significant recognition for his contributions to political philosophy:

• Gottfried Wilhelm Leibniz Prize (2012), Germany's highest research honor
• Member of the Berlin-Brandenburg Academy of Sciences and Humanities
• Corresponding Fellow of the British Academy
• Permanent Fellow at the Research College for Human Sciences Bad Homburg

As an educator and mentor, Forst has directed numerous research initiatives and supervised many doctoral students who have gone on to prominent academic positions. He leads the international MA program in Political Theory funded by the German Academic Exchange Service and has established several significant research centers including the Research Center for Normative Orders, the Leibniz Prize Research Group "Transnational Justice," and the Center for Advanced Studies "Justitia Amplificata." His editorial work includes serving as Associate Editor of Ethics and member of editorial boards for numerous prestigious journals including Political Theory and Constellations.

Forst's research infrastructure includes the Research Center for Normative Orders, which he directs, and the cluster initiative "ConTrust – Trust in Conflict," which examines political coexistence under conditions of uncertainty. His Leibniz Prize Research Group "Transnational Justice" investigates justice beyond national borders, while the Justitia Center for Advanced Studies serves as a hub for interdisciplinary research on justice-related topics. These institutions form an integrated network supporting collaborative research across philosophy, political science, and law.
