Samuel A. Oppenheim, the author of The Historical Evolution Of Judaism, With Comparisons To Other Systems Of Thought, traces the evolution of the Jewish religion as a response to historical events, and how its development interacts with the history of Jews as individuals and the outside world, and how Judaism compares to other religions. The author presents the text in a format to help the reader gain a better and more thorough understanding of Judaism and its interconnection both with Jewish history and other systems of thought, with specific emphasis on Islam and Christianity.
