Economists and other social scientists in this century have often supported economic arguments by referring to positions taken by philosophers of science. This important new book looks at the reliability of this practice and--in the process--provides economists, social scientists, and historians with the necessary background to discuss methodological matters with authority. Redman presents an accurate, critical, yet neutral survey of the modern philosophy of science from the Vienna Circle to the present, focusing particularly on logical positivism, sociological explanations of science (Polanyi, Fleck, Kuhn), the Popper family, and the history of science. She then deals with economic methodology in the twentieth century, looking at a wide range of methodological positions, especially those supported by positions from the philosophy of science.
