Programme

Dies natalis lecture
The renounced oath. About freedom of conscience and academy, by Egbert Koops, professor of Legal History.
Can you expect scientists to propagate certain views, or not to propagate them? In the beginning, Leiden University asked staff and students to take an oath. That didn't work out. The oath was renounced. Immediately the noble principles of freedom of conscience and academia were put to the test. In his Dies lecture, Egbert Koops examines the boundaries of academic freedom, then and now.
