impossible to give a full account of the Creation to man. Therefore Scripture simply tells us, In the beginning God created the heavens and the earth” (Gen. i. 1). Thus they have suggested that this subject is a deep mystery, and in the words of Solomon, “Far off and exceedingly deep, who can find it out?” (Eccles. vii. 24). It has been treated in metaphors in order that the uneducated may comprehend it according to the measure of their faculties and the feebleness of their apprehension, while educated persons may take it in a different sense. In our commentary on the Mishnah we stated our intention to explain difficult problems in the Book on Prophecy and in the Book of Harmony. In the latter we intended to examine all the passages in the Midrash which, if taken literally, appear to be inconsistent with truth and common sense, and must therefore be taken figuratively. Many years have elapsed since I first commenced those works. I had proceeded but a short way when I became dissatisfied with my original plan. For I observed that by expounding these passages by means of allegorical and mystical terms, we do not explain anything, but merely substitute one thing for another of the same nature, whilst in explaining them fully our efforts would displease most people; and my sole object in planning to write those books was to make the contents of Midrashim and the exoteric lessons of the prophecies intelligible to everybody. We have further noticed that when an ill-informed Theologian reads these Midrashim, he will find no difficulty; for possessing no knowledge of the properties of things, he will not reject statements which involve impossibilities. When, however, a person who is both religious and well educated reads them, he cannot escape the following dilemma: either he takes them literally, and questions the abilities of the author and the soundness of his mind—doing thereby nothing which is opposed to the principles of our faith,—or he will acquiesce in assuming that the passages in question have some secret meaning, and he will continue to hold the author in high estimation whether he understood the allegory or not. As regards prophecy in its various degrees and the different metaphors used in the prophetic books, we shall give in the present work an explanation, according to a different method. Guided by these considerations I have refrained from writing those two books as I had previously intended. In my larger work, the Mishnah Torah, I have contented myself with briefly stating the principles of our faith and its fundamental truths, together with such hints as approach a clear exposition. In this work, however, I address those who have studied philosophy and have acquired sound knowledge, and who while firm in religious matters are perplexed and bewildered on account of the ambiguous and figurative expressions employed in the holy writings. Some chapters may be found in this work which contain no reference whatever to homonyms.
