This is Volume III of eighteen in collection on Political Sociology. Originally published in 1948, this is an empirical approach to the analysis of political behaviour. The present volume contains a selection of Prof. Lasswell's articles and papers on politics— the science and the art of management —written from the point of view of a man deeply[1]intent on making Democracy a working institution. It covers international political experiments and experiences of person-to-person relationships, morals, religion and quasi-religious movements; techniques of public opinion are scrutinized as well as the workings of the mind and the subconscious.
