“Truth is concrete,” a quote Lenin borrowed from Augustine and Hegel, was written in big letters over Bertolt Brecht’s desk during his exile in Denmark from Nazi Germany. It was a reminder during a time of extreme political unrest never to forget the reality around him. The organizers of this book adopted this quote as the working hypothesis for a week-long marathon event/happening, running day and night, that aimed to facilitate and promote direct action, transparency and knowledge exchange among the hundreds of artists, activists, theorists, students and young professionals who attended. The result is a content-packed document with over 99 contributions ranging from Pussy Riot, Rabih Mroué and Slavoj Žižek, describing tactics and strategies for dissent, to a wide range of academics, including Steve Lambert, Alanna Lockward and Jonas Staal, focusing on philosophical and historical modalities of altruistic artistic practices. Viva la revolution!
