By taking an abstract, philosophical stance, students will learn how to think about sciences in a philosophical manner – that is, regarding science in general and regarding their own respective disciplines. They shall understand how sciences function epistemically and socially. We will start with a Knowledge Café. There will also be mini- lectures and exercises in groups (e.g., performative re-enactments of famous episodes regarding scientific reasoning in social contexts). Participants are encouraged to bring their lunch.
