DIRT: Laurie Taylor explores its material & symbolic meanings. Stephanie Newell, Professor of English at Yale University, traces the ways in which urban spaces and urban dwellers come to be regarded as dirty, as exemplified in colonial and postcolonial Lagos,Nigeria. They’re joined by Lucy Norris, Guest Professor of Design Anthropology and Material Culture at the Weissensee School of Art and Design, Berlin, who asks if the resistance to recycled clothes relates to our fear that they may intimately link us with 'dirty' & contagious bodies.
