The laws are intended to promote man’s perfection; they improve both his mental and his physical condition; the former in so far as they lead him to the acquisition of true knowledge, the latter through the training of his moral and social faculties. Each law thus imparts knowledge, improves the moral condition of man, or conduces to the well-being of society. Many revealed laws help to enlighten man, and to correct false opinions. This object is not always clearly announced. God in His wisdom sometimes withheld from the knowledge of man the purpose of commandments and actions. There are other precepts which tend to restrain man’s passions and desires. If the same end is occasionally attainable by other means, it must be remembered that the Divine laws are adapted to the ordinary mental and emotional state of man, and not to exceptional circumstances. In this work, as in the Yad ha-ḥazaḳah, Maimonides divides the laws of the Pentateuch into fourteen groups, and in each group he discusses the principal and the special object of the laws included in it. In addition to the legislative contents, the Bible includes historical information; and Maimonides, in briefly reviewing the Biblical narratives, shows that these are likewise intended to improve man’s physical, moral, and intellectual condition. “It is not a vain thing for you” (Deut. xxxii. 47), and when it proves vain to anyone, it is his own fault. In the final chapters the author describes the several degrees of human perfection, from the sinners who have turned from the right path to the best of men, who in all their thoughts and acts cling to the Most Perfect Being, who aspire after the greatest possible knowledge of God, and strive to serve their Maker in the practice of “loving-kindness, righteousness, and justice.” This degree of human perfection can only be attained by those who never forget the presence of the Almighty, and remain firm in their fear and love of God. These servants of the Most High inherit the choicest of human blessings; they are endowed with wisdom: they are godlike beings. INTRODUCTION [Letter of the Author to his Pupil, R.
