SВїren Kierkegaard's philosophy intersects with so many systems of thought--theology, religion, existentialism, literature and psychology, as examples--that it is difficult to classify or to grasp the concepts that he presents. Yet Kierkegaard's influence on the 20th century is vital, and therefore an understanding of his thinking is as well. The ''Historical Dictionary of Kierkegaard's Philosophy'' is a guide to the secondary material that exists on the Danish thinker. Beginning with maps and a contextual introduction to the 19th century world of Copenhagen, the philosopher's home, the dictionary includes a chronology of events and key figures in his life, as well as a guide to some of his concepts and terms and a list of major works. The bibliographical section contains entries on other handbooks and electronic materials of help to researchers. In the appendix, more detailed information on his writings is included, along with a list of his pseudonyms. Not only is this book to guide the reader new to Kierkegaard, but it is also a compilation that will be of great use to established scholars.
