For episode 14 of Pop Apocalypse, we welcome the linguist and philosopher Wouter Kusters. Kusters is the author of Pure Madness (2004) and A Philosophy of Madness (2014), both of which won the Dutch Socrates Award for best philosophy book of the year. We discuss how the experience of psychotic thinking challenges and illuminates our notions of language, philosophy, and mysticism. Along the way, we touch on the similarities between mystical and mad experiences, apophatic and psychotic uses of language, the phenomenology of time, and the impact of Kusters’ books on mental health specialists.
