This book is an American translation of Freud's "Hemmung, Symptom und Angst. " Many regard this book as the most valuable clinical one written by Freud up to that date. "The Problem of Anxiety" by focuses on Freud's theory of anxiety-neurosis. This is a comparatively small book, but the large number of topics brought together and the serious attempt to deal with them in a fundamental way stamps it as one of the author's major works. One notes throughout this book a scientific modesty and an attitude of non-finality which was not always apparent in Freud's earlier writings.
