DIE APOTHEKE DER SELBSTÜBERWINDUNG transforms philosophy into matter, preparation and action. The installation continues Vierling’s series Hegel · Marx · Kant · Nietzsche, first developed in 2019 as pharmaceutical formulations: Hegel ointment, Marx hand cream, Kant lotion and Nietzsche suppositories. In the 2026 installation, the pharmacy becomes a functioning production site. Philosophical material is extracted, weighed, heated, mixed, cast, bottled and packaged. At its centre is Nietzsche’s Überzäpfchen: a complete edition of Nietzsche’s writings is physically penetrated by a laboratory apparatus and becomes the source of Nietzsche-Wasser. Philosophy passes from book to substance, from substance to preparation, and from preparation toward the body. Nietzsche must pass through the body. The pharmacy is not a representation of a laboratory. It operates. During the performance, Hegel-Salbe, Marx-Handcreme, Kant-Lotion and Nietzsche’s Überzäpfchen are produced as material formulations of philosophical positions. The work asks what happens when thought is no longer only understood, but incorporated, handled and transformed.
