ZEI Discussion Paper C 278 / 2023

Europäische Integration aus historischer Erfahrung. Ein Zeitzeugengespräch mit Michael Gehler - Ralf Dahrendorf

This interview takes place within the framework of the contemporary witness interviews "European Integration from Historical Experience", which attempts to record all former commissioners from Germany in interview form. In the case of already deceased commissioners, the conversations were reconstructed retrospectively on the basis of their contemporary interviews, publications, writings and works. In the footnotes to the answers, the year of the statement is given in brackets, so that a historical classification is possible. The answers have been taken over tel quel as they were in the original.

ZEI Discussion Paper C 277 / 2023

Die Päpste, Europas Einigung und ein zerrissener Kontinent. Eine Zwischenbilanz im Lichte der gegenwärtigen Krisen in Kirche und Welt - Ludger Kühnhardt

The relationship of the Popes to the continent of Europe has been and remains ambivalent. It oscillates between the global orientation of the Roman Catholic Church and the defense of the faith, but also between a reserved and skeptical attitude towards Western modernity and an almost naïve hope for ecumenical dialogue with the Russian Orthodox Church. In the midst of the current global political crisis, ZEI Director Ludger Kühnhardt reconstructs the perspectives of seven popes during seven decades of European unity and the ongoing disunity of the European continent.

Das politische Denken der Europäischen Union

Supranational und zukunftsoffen. by Ludger Kühnhardt

The European Union should be based on the idea of European sovereignty, as French President Emmanuel Macron designed the future of the EU in 2017. The concept of European sovereignty connects questions of political thought with the internal order and the global political strategy of the EU. From a historical perspective, modern political thought has evolved around the concept of the state. However, ancient roots of political thought indicate that fundamental questions of political order were already reflected in a context prior to the evolution of the modern state. Important concepts of political philosophy emerged in ancient Greek and Roman history that continue to have an impact today. Against this background, this textbook Ludger Kühnhardt discusses in this innovative text book whether and how political thinking can also generate its own concepts and reflections in a supranational context, and especially in the European Union..
