Machiavelli to Hannah Arendt, the great age of natural law to contemporary debates between "liberal" and "Community", the concept of power runs parallel to the political reflection of modernity, marking the story and the character in a game extraordinarily rich continuity and problematizations. This is well seen, the center of a dense network of concepts that still defines the horizon of our way of thinking about politics. Product of a joint research, this volume attempts to provide an overall look and at the same time, a critical perspective on the history of modern and contemporary political thought, putting in central theme of power and logic concepts that are connected in this. Without losing sight of the texts of political thinkers, the various chapters of the book follow the thread of Genesis, of change, of the fate of political categories of modernity, aware that neither the isolated voices of traditional "lexical" or the mere reconstruction of the "contexts" can restore the historical and theoretical depth of an extremely complex web of thoughts and ideas. Giuseppe Duso History teaches political philosophy at the University of Padua and a member of the board of Political Philosophy.
