Why has American political science, as a knowledge summary of regional political experience, become Western politics and even politics itself? How has American political science distinguished itself from European politics? How has American political science become a lame giant of(specialized and scientific) research by excluding teaching, political education and practical application? How does American political science write the history of politics after expelling historical analysis from the methodological domain of political science? We can see these problems when we read Handbook of Political Science(1975) and A New Handbook of Political Science(1996) in a comparative way.
