摘要:Social science is like New York City. It looks bright and shiny from a distance, less impressive up close, and its core—like 42nd street—is soft, if not rotten. Sociologists are unable to define sociology; political scientists cannot agree on a definition of politics, and schools of economists battle like medieval warriors in suits of ideological armor.1 In social science generally, there is little agreement as to how key terms should be defined and used. For example, there is great confusion as to meaning of rationality, which should be one of the key concepts of the social sciences.2 M.I.T. economist Lester Thurow inadvertently illustrates the problem in his classic book, The Zero Sum Society.
