This book examines the central questions of democracy and politics in modern societies. Through an analysis of some of the key texts of 19th and 20th century thought - from Marx, Michelet and de Tocqueville to Hannah Arendt - the author explores the ambiguities of democracy, the nature of human rights, the idea and the reality of revolution, the emergence of totalitarianism and the changing relations between politics, religion and the image of the body. While developing a highly original account of the nature of politics and power in modern societies, he links political reflection to the interpretation of history as an open, indeterminate process of which we are part. This work should interest specialists in social and political theory and philosophers.
