Theory Tuesdays is a nonacademic platform for theoretical discussion founded, organized and coordinated by artist Philip Matesic since 2009. Participants read beforehand then discuss contemporary art, design, literary, cultural and critical theory on a weekly basis, with the texts selected and introduced each week by a different person.

The discussions are a blend of knowing and not-knowing, being critical and playful, each one teaching the other. By being free and open to the public, the weekly circulation of varying topics and presenters makes it possible to just drop in and discuss. The sessions are held in English and German, depending on the written language of the PDF.
