This book is yet another deep, original and controversial contribution of Hannah Arendt to twentieth century political theory. In this book, Arendt analyzes the phenomenon of revolution by focusing almost exclusively on the great XVIIIth century revolutions, the American and the French. Arendt???s deep insights allow her to compare, both on a theoretical and a practical level, the similarities and differences between the two and on how and why the American Revolution allowed the foundation of freedom while the French failed miserably in this attempt almost from the beginning. The great themes in this book are the social question (necessity) in its relation to politics (the realm of freedom) and the ever-present distinction between liberation and freedom properly speaking. Thus, constitutions and their significance, the problem of secular law in relation to its need for an Absolute with which to provide a foundation for it, the problem of hypocrisy and Robespierre???s Terror, and insightful interpretations of some of the Founding Fathers??? political thought (though in my opinion a bit too far reaching in her inferences thereof), are all issues with which she deals with in this book and which are rounded up in a great closing chapter. Deep, powerful, perceptive, intense: like most of Arendt???s writings, a must read for anyone interested in political thought and theory.
