The book is divided in three sections, covering various phenomena of borders and their possible debordering. The first section offers insights into bordering topologies, from reflections on the U.S. border to the development of the concept of the "border" in ancient China. The second section is dedicated to practices as well as intellectual ontologies with practical implications bound up with borders in different cultural and social spheres - from Buddhist nationalism in Sri Lanka and Myanmar to contemporary photography with its implications for political systems and reflections on human/animal border. The third section covers reflections on hospitality that relate to migration issues, emerging material ethics, and aerial hospitableness.
