Chair for International Political Theory and Philosophy

I am a political and environmental philosopher/theorists working on normative issues. I’ve published on Marxism, Rawls,  Global Justice, Just War Theory, Reconciliation, and other matters.

Most (but not all) of my research currently is in three broad  areas: Climate change and justice; the meaning and normative significance of the Anthropocene; and hope. I can supervise Bachelor theses in either German or English, but Master theses and Doctoral dissertations only in English.

The Examined Illness: A Philosophical Confession in Micro Essays (Unpublished)

 “This is what you shall do: Love the earth and sun and the animals, despise riches, give alms to everyone that asks, stand up for the stupid and crazy, devote your income and labor to others, hate tyrants, argue not concerning God, have patience and indulgence toward the people, take off your hat to nothing known or unknown or to any man or number of men, go freely with powerful uneducated persons and with the young and with the mothers of families, read these leaves in the open air every season of every year of your life, re-examine all you have been told at school or church or in any book, dismiss whatever insults your own soul; and your very flesh shall be a great poem and have the richest fluency not only in its words but in the silent lines of its lips and face and between the lashes of your eyes and in every motion and joint of your body.”  —  Walt Whitman, Preface, Leaves of Grass, 1855.

“Oh, what'll you do now, my blue-eyed son?
Oh, what'll you do now, my darling young one?
I'm a-goin' back out 'fore the rain starts a-fallin'
I'll walk to the depths of the deepest black forest
Where the people are many and their hands are all empty
Where the pellets of poison are flooding their waters
Where the home in the valley meets the damp dirty prison
Where the executioner's face is always well-hidden
Where hunger is ugly, where souls are forgotten
Where black is the color, where none is the number
And I'll tell it and think it and speak it and breathe it
And reflect it from the mountain so all souls can see it
Then I'll stand on the ocean until I start sinkin'
But I'll know my song well before I start singin'
And it's a hard, it's a hard, it's a hard, it's a hard
It's a hard rain's a-gonna fall”

--Bob Dylan, A Hard Rain’s a-Gonna Fall, 1962.
