A number of papers on key ideas in the social sciences are made available to Americans for the first time in this book. Representative of Western European culture, Roberto Michels, author of the famous POLITICAL PARTIES and many other works, asks and gives answers to a number of questions basic to the further study of political behavior, social-economic institutions, and public law. There parade before the reader of this volume the really great European contributors to social science of the last century: Saint-Simon, Karl Marx, Gabriel Tarde, Gaetano Mosca, Vilfredo Pareto, Max Weber, Werner Sombart, Georges Sorel, and many other critics and scholars. At every step the sociologist, the economist, the psychologist, and the political scientist -- for Michels was all of these -- intermingle and reinforce each other. German born, Roberto Michels studied at Paris, Munich, Leipzig, Halle, and Turin, and taught successively in some of Europe’s greatest universities. In 1927 he lectured in America at the University of Chicago and elsewhere.
