Originally published in 1927, this book was written as a reaction to the First World War, hoping to try and analyse the causes leading up to it. The author states in the Preface that he puts this forward as an unsystematic contribution to what he is conscious is a very great subject, and he adds since Aristotle, an almost untouched one. He starts by looking at the nature, methods and uses of history, considered from a political point of view. He goes on to look at the possibility of a political science; the place of politics among the social sciences, and the process of politics. In conclusion he considers the relation of politics and ethics.
