This collection of essays investigates the convergence between the postmodern politics of mobility and a politics of metaphor, a politics, in other words, in the context of which the production and displacement of meaning(s) constitute the major stakes. Ranging from discussions of re-territorialization, multiculturalism, "digisporas" and transnational politics and ethics, to September 11th, the Pentagon's New Map, American legislation on Chinese immigration, Gianni Amelio's film Lamerica, Keith Piper's online installations and Doris Salcedo's Atrabiliarios, the collection aims to follow three different theoretical trajectories. First, it seeks to rethink our concepts of mobility in order to open them up to the complexity that structures the thoughts and practices of a global order. Second, it critically examines the privileged position of concepts and metaphors of mobility within postmodern theory. In juxtaposing conflictual theoretical formulations, the book sets out to present the competing responses that fuel academic debates around this issue. Finally, it evaluates the influence of our increasingly mobile conceptual frameworks and everyday experience on the redefinition of politics that is currently under way, especially in the context of Post-Marxist theory. Its hope is to contribute to the production of alternative political positions and practices that will address the conflicting desires for attachment and movement marking postmodernity.
