What is the meaning of life, the essence of the world, and man's position in the world? What can I know? What do you think I should do? What can I hope? In this series of events, we want to philosophize, reflect, and speculate together. The setting for this is Café Leye, right in the pedestrian zone of downtown Witten. On five evenings during the summer semester, we will again devote ourselves to exciting texts by outstanding philosophers. A different expert will lead each of these evenings. The events in this series are free of charge and open to all interested parties. Registration is not necessary.
