Of the number of reprints appearing in recent years this volume is of outstanding importance. Published in German in two volumes, 1875 and 1898 respectively, and later translated into English by Charles E. Hay, it has been out of print in this translation for a number of years. It is an indispensable aid and guide in reference work as well as a textbook for detailed study.
Due to its age, it lacks treatment of doctrinal history under the impact of modern philosophical thought and modern science. In so far as it carries the development of dogma however the book is an excellent text.
