Book excerpt: The condition of borders has been crucial to many recent exhibitions, conferences and publications. But there does not yet exist a convincing critical frame for the discussion of border discourses. Rethinking Borders offers just such an introduction. It develops important contexts in art and architectural theory, contemporary film-making, criticism and cultural politics, for the proliferation of 'border theories' and 'border practices' that have marked a new stage in the debates over postmodernism, cultural studies and postcolonialism.
