<p>Mario Bunge, author of the monumental Treatise on Basic Philosophy, is widely renowned as a philosopher of science. In this new and ambitious work he shifts his attention to the social sciences and the social technologies. He considers a number of disciplines, including anthropology, sociology, economics, political science, law, history, and management science.</p><p>Bunge contends that social science research has fallen prey to a postmodern fascination with irrationalism and relativism. He urges social scientists to re-examine the philosophy and the methodology at the base of their discipline. Bunge calls for objective and relevant fact-finding, rigorous theorizing, and empirical testing, as well as morally sensitive and socially responsible policy design.
