“We humans have trouble with borders and border crossing—psychologically, socially, culturally, intellectually, artistically, economically, and politically as well as ecologically and geopolitically. This is the case in particular in twenty-first-century society faced, as it is, with multiple intertwined crises impacting every level. In this collection, 24 authors of diverse nationalities and disciplinary backgrounds probe this knotty problem relative to a variety of regions of the globe. Overall, their varied explorations amount to nothing less than a journey across borders, opening paths toward sustainable and humane survival. One comes away with an acute sense that the ideas of borders and border crossing matter—to us and the society in which we live right now.” —Piet Strydom, University College Cork, Ireland.
