This exciting new book makes a major contribution to Continental philosophy, bringing together for the first time the crucial work on politics by two giants of contemporary French philosophy, Jacques Derrida and Alain Badiou. Derrida has long been recognised as one of the most influential and indeed controversial thinkers in contemporary philosophy and Badiou is fast emerging as a central figure in French thought, as well as in Anglo-American philosophy - his magnum opus, "Being and Event", and its long-awaited sequel, "Logics of Worlds", have confirmed his position as one of the most significant thinkers working in philosophy today. Both philosophers have devoted a substantial amount of their oeuvre to politics and the question of the nature of the political. Here, Antonio Calcagno shows how the political views of these two major thinkers diverse and converge, thus providing a comprehensive exposition of their respective political systems.Both Badiou and Derrida give the event a central role in structuring politics and political thinking and Calcagno advances a theory about the relationship between political events and time that can account for both political undecidability and decidability. This book navigates some very intriguing developments in Continental thought and offers a clear and fascinating account of the political theories of two major contemporary thinkers.
