"Maimonides divided his work into two parts. Part I presents the Fourteen Principles by which, in his view, it is to be determined which Commandments are to be included in the Taryag Mizvoth, and which are not. He defines these principles with great care, and establishes their validity with irrefragable logic and with a profound insight into the subtleties of Rabbinic law. Part Ii consists of a detailed presentation of the 613 Commandments. These are divided into Two Hundred and Forty-eight Positive Commandments, and Three Hundred and Sixty-five Negative Commandments. The author supports his statements with a wealth of evidence gathered from the entire field of Rabbinic literature, in each case making it clear to the reader beyond doubt whether any specific command to do or to abstain from doing constitutes a distinct mitzvah in itself, or is only an incidental part of a mitzvah." - Foreword.
