I have further philosophical interests, for example in the philosophy of mind and the philosophy of biology. At University College Groningen, I teach courses on logic, philosophy of science, and risks to the survival of humanity ("existential risks"). Here is an outline of what is done in that course. I sympathize with the Effective Altruism movement, and in environmental matters I subscribe to a version of "ecomodernism", as articulated in Jonathan Symons' wonderful book. I am co-founder and chair of a German ecomodernist society, on whose webpage Ökomoderne, part of the European network RePlanet. Sometimes I'm on display on their Who We are page.

Human flourishing seems to require access to relatively cheap energy. But these days that energy comes mostly from burning fossil fuels, which in turn threatens human flourishing by contributing to climate change. I am particularly intrigued by the question whether, from an ethical point of view, we should invest a significant amount of resources in further development and deployment of nuclear energy in addition to increasingly harvesting surrounding energy flows such as solar and wind energy. In academic (here and here) and political contexts I have given talks on the ethics of nuclear energy deployment in the age of climate change, and I have appeared in German media, e.g. Handelsblatt and Klima und wir.

And I play the piano. Here are some recordings (I plan to add more): Beethoven's piano sonatas op. 2.1 (Allegro, Adagio, Menuetto: Allegretto, Prestissimo), op. 2.2 (Allegro vivace, Largo appassionato, Scherzo: Allegretto, Rondo: Grazioso), op. 2.3 (Allegro con brio, Adagio, Allegro, Allegro assai), op. 13 (Grave -- Allegro molto e con brio, Adagio cantabile, Rondo: Allegro), op. 14.1 (Allegro, Allegretto, Allegro comodo), op. 14.2 (Allegro, Andante, Allegro assai), op. 106 ("Hammerklavier", Allegro, Scherzo: Assai vivace, Adagio sostenuto, Largo -- Allegro risoluto) and Medtner's fairy tale op. 20.1.
