Query: THE masterpiece in history of economic thought

After the considerable success of his then only in germanpublished Little Sketch of Doctrines and Methods, and while he wasteaching at Harvard, Schumpeter started working on a book wich would cover the ground of Little Sketch an beyond. What began just as leisure would become THE masterpiece in History of Economic Thought. Schumpeter spent ten years in this colossal effort and unfortunately did not finish it before his death. Nevertheless, nowhere else you will find a book more powerful and more profound on this theme. By History of Economic Analysis Schumpeter means the history of efforts made in the pursuit of comprehending economic phenomena, from Antiquity to present; not a book on history of ideologies. Schumpeter places the authors in their times and contexts, and tries to understand how they proceeded in analysing economic reality. A must for anyone interested in economic theory, history and philosophy.
