A frequent criticism of contemporary political science is that empirical research too seldom is combined with in-depth inquiry into the philosophical, historical, and legal foundations of the societies it seeks to understand. Others suggest that political scientists specializing in U.S. government too rarely collaborate with those who study other countries. The contributions in this volume belie these claims. The authors, all colleagues, students, and friends of Henry W. Ehrmann, represent the U.S., France, Germany, and Canada, the four countries in which Dr. Ehrmann has lived. The essays reflect the breadth and scope of Ehrmann's work as a teacher, scholar, and political activist. The contributions to this volume cover a broad range of topics, among them political theory and methodology of comparative politics and the interrelationships of economic, social, historical, and political developments, and include theoretically oriented studies of such problems as interest group politics, political culture, and parties. Integrating constitutional law and political philosophy with comparative sociological and historical research and theory, Henry Ehrmann's approach to teaching and research sets an excellent example for the contemporary study of political science.
