Karl Mittermaier argued that much had been accomplished in developing the tools of economics, but little in understanding its subject matter.Published posthumously with an introduction from Michael Stettler, this book illustrates his point, showcasing that some of the difficulties economics is dealing with is the result of a stance, and develops a conceptual framework to address these issues.Presenting the previously unpublished works of an influential economist from the 21st century, this is a seminal text for the philosophy of social sciences and a valuable contribution to current debates.
