The machine world we have created is gradually taking on autonomy and power. To remedy this catastrophe, to avert this dispossession, we rely on communication. A magical concept, the new science and liturgy of our new century. Communication, in all its forms, will save our society. Are we sure? Here the author promotes the systematic exploration and radical critique of this new science (which already has its schools, its laboratories and its great priests). Lucien Sfez is professor of political science at the University of Paris. His numerous works have contributed extensively to modern political science.
