In the course of philosophy, conceptual notions come to the fore and recede into the background. Do they become obsolete, superfluous, like ladders that you can throw away after climbing them, as Ludwig Wittgenstein said? In encyclopaedias one finds terms and their explanations. We have collected philosophical terms that seem obsolete to us – and together we form a sound space, to taste them again, like words of a long forgotten language, by articulating them, for possible reflection – or to say goodbye, never to see them again?

The performance Obsolete Philosophical Notions took place at art space Netwerk Aalst, 12 September 2020. Speakers: Annelies Monseré, Nadia Sels, Andrea Knoflach, Maarten Van Ingelgem, Volkmar Mühleis. Video: Felix Kindermann; post production: Koenraad Cant. With many thanks to Pieternel Vermoortel, Netwerk Aalst.

Presentation: 9 October 2020, on the symposium Perform Philosophy, LUCA School of Arts, Ghent, on the occassion of the yet published Routledge Companion to Performance Philosophy.
