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 have some sympathies for the Effective Altruism movement and, in environmental matters, with "ecomodernism" as characterized by my friend Jonathan Symons in his wonderful book. I once co-founded and chaired a German ecomodernist society, which, in the meantime, has morphed into WePlanet DACH, part of the European network WePlanet.
