Abstract: George Reisman’s magnum opus Capitalism: A Treatise on Economics is a monumental attempt at theoretical integration of leading economic phenomena into one unified whole. Few such books have been published in the history of economics. Still fewer of them contain a comparable proportion of path-breaking innovations both in approach and substance that are integrated in a tightly-spun system of thought that Capitalism does. Yet despite its numerous path-breaking contributions to economic theory, the book has attracted virtually zero attention from the scientific community. History shows that for the most part this has been the fate of all great innovations in science. This review attempts (a) to point out reasons why the book’s content is revolutionary, and (b) to finally start a serious discussion of its substantive ideas. Specifically, the review focuses in some detail on some of Reisman’s most important innovations which all point the way to a wholly new direction in economic theory that promises to provide the hitherto unseen conformity with empirical reality, analytical rigor, and doctrinal integration.
