Lessico della Politica is a series of books directed by Carlo Galli. Since its inauguration in September 1999 eleven titles have been published: Constitution, Representation, Liberty, State, Democracy, Tolerance, Revolution, Government, Community and Authority. The aim of this series is to create an essential encyclopedia which by explaining important political concepts and, in particular, their historic evolution provides a non-expert reader with the historical and theoretical rudiments of contemporary politics. The sixth volume of the series is dedicated to the concept of interest, a fundamental and constructive element of politics which has always had an ambivalent nature testified by the opposing meanings of "the fruit of money" and "damages". The authors follow the evolution of this concept from the ancient notion of profit to the notion of interest, passing through the cosmos of interests of the Ancien Rgime, State interest, National interest and the democracy of interests.
