 A new cycle was initiated with One-Way Street (Einbahnstraße), written 1923–6, published 1928), whose form and content puts into practice that speculative concept of experience, with its allegorical immersion into the depths of things, which was theoretically articulated in the works considered above. The city furnishes the sensuous, imagistic material for One-Way Street, whilst the genres of the leaflet, placard and advertisement provide the constructive principle by which it is rearranged as a constellation.  This formal methodology resembles the technological media of photography and film, as well as the avant-garde practices of Russian Constructivism and French Surrealism. This entails what Adorno describes as a “philosophy directed against philosophy” (Adorno 1955, 235) or what Howard Caygill calls a “philosophizing beyond philosophy” (Caygill 1989, 119).
