This collection presents a detailed 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 readily discern Pareto's specific contributions without losing sight of the fact that each element of his work is a component of a broad, system-wide social framework. The set contains important material for historians of economic thought, also historians of sociological ideas and methodology.* Volume One covers Pareto and the Scope of this Work* Volume Two covers Economic Theory* Volume Three covers Political Economy* Volume Four covers Pareto's Law and other specialised topics
