This theme reflects on the glues and fissures of cosmopolitanism. Saeed bin Mohammed forwards a discussion of cosmopolitanism as a “theoretical framework” but one that attends to issues of justice, openness, and inclusion through the post-war figure of UNESCO. Renée Marlin-Bennett speaks to the borders that cosmopolitanism traverses. She describes the “the emotional resonances of borders, the places in which one ontology—one state of being—is exchanged for or gives way to or is taken over by another.” Joanna Zielińska visits the medieval city of Sarajevo literally through a different lens. Her documentary and commentary present Sarajevo through the voices of six women and the feminine narrative that is often overlooked in the cultural histories of cities. Sascha Priewe discusses the cultural roots of cities to then address the pathologies they face. He writes that “to deal with the challenges that cities and the world are facing, to stem the populist tide and to manage life alongside one another in the densest and most connected human agglomerations, a systematic and holistic approach to culture and its global dimensions needs to happen.” The way to move forward is through networks of cultural diplomacy. The World Cities Culture Forum is an example.
