Frequently hailed as one of the greatest defenders of democratic liberalism in postwar Europe, Raymond Aron left behind a staggering amount of published work on a remarkably wide range of topics, both scholarly and popular. While trained in philosophy, Aron nevertheless left his mark on such fields as economics, sociology, nuclear strategic thought, and international relations. A Politics of Understanding assesses the originality and consistency in Aron's corpus, especially in the areas of international relations theory and strategic thought, and provides a concise and clearly written explanation of the basic concepts at work in Aron's philosophy.
