This collection presents an overview of Pareto's vast intellectual legacy and considers both theoretical and applied contributions. The articles are thematically arranged and the themes most closely linked are included in single volumes. This arrangement allows historians of economic thought to discern Pareto's specific contributions without losing sight of the fact that each element of Pareto's work is a component of a broad system wide social framework. The set contains material for historians of economic thought, but also historians of sociological ideas and methodology. Volume One covers Pareto and the scope of his work. Volume Two covers economic theory, while Volume Three covers political economy. Volume Four covers Pareto's Law and other specialized topics.
