It is a real honour to congratulate the University of Amsterdam on establishing the Vossius Centre. Research at the Vossius Centre touches upon one of the most central issues of our times: why and how knowledge branches out, how methodologies are historically formed, institutionalised or disappear. With a special focus on the effects of a 19th century (Anglophone) distinction between ‘humanities’ and ‘science’, it invites researchers to think post-disciplinarily and to innovate through interaction.
