Prof. Dr. Darrel Moellendorf

The cluster professorship is located at the interface of political science and philosophy and examines in particular phenomena that transcend national borders.

Central topics of the professorship are: The idea and meaning of human dignity in political justifications; the moral value and proper targeting of sustainable development; the rationale and role of socio-economic rights for human development; the identification of appropriate goals for the post-2015 sustainable development agenda; the requirements for equitable international trade and financial regimes; the causes of poverty and global inequality; the equitable distribution of obligations to mitigate climate change and the burden of climate adaptation; the identification of appropriate international climate change regimes; the relevance of geoengineering for climate policy; the justification and practicalities of sustainable development through an international tax system; and finally, the moral foundations of cross-border solidarity.

The work in the field of normative theories of global justice is in many respects based on empirical analyses in the areas of politics, economics, law and international relations, insofar as these deal with transnational problems. Based on these studies, the associated forms of normativity in transnational politics are examined and reflected upon at the professorship. Many questions concerning normative orders of environmental crises reveal similar modes of reflexivity and also focus on interdisciplinary questions of the normativity of intergenerational orders.

Our publications and presentations focused on issues of global justice, global bioethics, human rights, just war theories and environmental racism. The key findings were presented in publications and presentations.

Darrel Moellendorf has published on the question of how a war can be brought to a just end and on the question of whether a state can restrict the emigration of citizens whose medical training it has financed. Daniel Callies also worked and published on the question of whether it can be legitimate to restrict the emigration of citizens whose medical training was financed by the state. Eszter Kolllár has written about justice, immigration and global equality of opportunity. And Merten Reglitz published an article on Kant, global poverty and justice. Daniel Hammer presented his work on collective action and personal responsibility in an international presentation. And Susanne Börner also presented her work on environmental justice in an international presentation. Brian Milstein gave a presentation on crisis theory. All of these topics are relevant to the political debate and many of the publications evaluate selected aspects of public policy.

Militärische KI verantwortungsvoll nutzen und Regulierung neu denken

Panel Discussion, Lecture

Künstliche Intelligenz findet im Militär immer breiteren Einsatz, von Logistik und Training über Missionsplanung und Zielidentifikation bis hin zu autonomen Waffensystemen. Gleichzeitig wächst die Bedeutung von Mikroprozessoren immer stärker, der Zugang zu seltenen Erden und Chips wird zur zentralen Ressource. KI kann das Kampfgeschehen beschleunigen und damit destabilisierend wirken. Der Wettlauf um neue Fähigkeiten birgt jedoch auch Eskalationsrisiken. Wir laden Sie ein, diese Themen im nächsten Crisis Talk gemeinsam mit unseren hochkarätigen Podiumsgästen zu diskutieren.

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.
