Contributor(s): Professor Wendy Brown | In this lecture, Professor Wendy Brown will draw on discourse analysis, psychoanalysis, and feminist theory to examine the desire for walls in the context of eroding sovereignty. Why the current proliferation of nation-state walls, especially amidst widespread proclamations of global connectedness and anticipation of a world without borders? And why barricades built of concrete, steel and barbed wire when threats to the nation today are so often miniaturized, vaporous, clandestine, dispersed or networked? Why walls now and how are they to be understood?
