I have composed this work neither for the common people, nor for beginners, nor for those who occupy themselves only with the Law as it is handed down without concerning themselves with its principles. The design of this work is rather to promote the true understanding of the real spirit of the Law, to guide those religious persons who, adhering to the Torah, have studied philosophy and are embarrassed by the contradictions between the teachings of philosophy and the literal sense of the Torah.
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.
To give a full explanation of the mystic passages of the Bible is contrary to the law and to reason; besides, my knowledge of them is based on reasoning, not on divine inspiration [and is therefore not infallible]. ...It is... possible that my view is wrong, and that I misunderstand passages referred to. ...Those, however, for whom this treatise has been composed, will, on reflecting on it and thoroughly examining each chapter, obtain a clear insight into all that has been clear and intelligible to me. This is the utmost that can be done in treating this subject so to be useful to all without fully explaining it.
You are no doubt aware that the Almighty, desiring to lead us to perfection and to improve our state of society, has revealed to us laws which are to regulate our actions. These laws, however, presuppose an advanced state of intellectual culture. We must first form a conception of the Existence of the Creator according to our capabilities; that is, we must have a knowledge of Metaphysics. But this discipline can only be approached after the study of Physics: for the science of Physics borders on Metaphysics, and must even precede it in the course of our studies, as is clear to all who are familiar with these questions.
Do not imagine that these most difficult problems can be thoroughly understood by any one of us. This is not the case. At times the truth shines so brilliantly that we perceive it as clear as day. Our nature and habit then draw a veil over our perception, and we return to a darkness almost as dense as before. We are like those who, though beholding frequent flashes of lightning, still find themselves in the thickest darkness of the night. On some the lightning flashes in rapid succession, and they seem to be in continuous light, and their night is as clear as the day. This was the degree of prophetic excellence attained by (Moses) the greatest of prophets, to whom God said," But as for thee, stand thou here by Me" (Deut. v. 31), and of whom it is written" the skin of his face shone," etc. (Exod. xxxiv. 29). [Some perceive the prophetic flash at long intervals; this is the degree of most prophets.] By others only once during the whole night is a flash of lightning perceived. This is the case with those of whom we are informed," They prophesied, and did not prophesy again" (Num. xi. 25). There are some to whom the flashes of lightning appear with varying intervals; others are in the condition of men, whose darkness is illumined not by lightning, but by some kind of crystal or similar stone, or other substances that possess the property of shining during the night; and to them even this small amount of light is not continuous, but now it shines and now it vanishes, as if it were" the flame of the rotating sword."
All the great evils which men cause to each other because of certain intentions, desires, opinions, or religious principles, are likewise due to non-existence, because they originate in ignorance, which is absence of wisdom. If men possessed wisdom, which stands in the same relation to the form of man as the sight to the eye, they would not cause any injury to themselves or to others, for the knowledge of the truth removes hatred and quarrels, and prevents mutual injuries.
An ignorant man believes that the whole universe only exists for him: as if nothing else required any consideration. If, therefore, anything happens to him contrary to his expectation, he at once concludes that the whole universe is evil. If, however, he would take into consideration the whole universe, form an idea of it, and comprehend what a small portion he is of the Universe, he will find the truth. There are many... passages in the books of the prophets expressing the same idea.

(4) Man is like a breath; his days are like a passing shadow.
This is our theory, or that of our Law. ...The theory of man's perfectly free will is one of the fundamental principles of the Law of our teacher Moses, and of those who follow the Law. According to this principle man does what is in his power to do, by his nature, his choice, and his will; and his action is not due to any faculty created for the purpose. All species of irrational animals likewise move by their own free will. This is the Will of God; that is to say, it is due to the eternal divine will that all living beings should move freely, and that man should have the power to act according to his will or choice within the limits of his capacity.
The strange and wonderful Book of Job treats of the same subject as we are discussing; its contents are a fiction, conceived for the purpose of explaining the different opinions which people hold on Divine Providence. ...This fiction, however, is in so far different from other fictions that it includes profound ideas and great mysteries, removes great doubts, and reveals the most important truths. I will discuss it as fully as possible; and I will also tell you the words of our Sages that suggested to me the explanation of this great poem.
The custom which was in those days general among all men, and the general mode of worship in which the Israelites were brought up, consisted in sacrificing animals in those temples which contained certain images to bow down to those images, and to burn incense before them; religious and ascetic persons were in those days the persons that were devoted to the service in the temples erected to the stars... It was in accordance with the wisdom and plan of God, as displayed in the whole Creation, that He did not command us to give up and to discontinue all these manners of service, for to obey such a commandment it would have been contrary to the nature of man, who generally cleaves to that to which he is used... By this Divine plan it was effected that the traces of idolatry were blotted out, and the truly great principle of our faith, the existence and Unity of God, was firmly established; this result was thus obtained without deterring or confusing the minds of the people by the abolition of the service to which they were accustomed and which alone was familiar to them.
Know that also in Natural Science there are topics which are not to be fully explained. Our Sages laid down the rule, "The Ma‘aseh Bereshith must not be expounded in the presence of two." If an author were to explain these principles in writing, it would be equal to expounding them unto thousands of men. For this reason the prophets treat these subjects in figures, and our Sages, imitating the method of Scripture, speak of them in metaphors and allegories; because there is a close affinity between these subjects and metaphysics, and indeed they form part of its mysteries. Do not imagine that these most difficult problems can be thoroughly understood by any one of us. This is not the case. At times the truth shines so brilliantly that we perceive it as clear as day. Our nature and habit then draw a veil over our perception, and we return to a darkness almost as dense as before. We are like those who, though beholding frequent flashes of lightning, still find themselves in the thickest darkness of the night. On some the lightning flashes in rapid succession, and they seem to be in continuous light, and their night is as clear as the day. This was the degree of prophetic excellence attained by (Moses) the greatest of prophets, to whom God said, "But as for thee, stand thou here by Me" (Deut. 5:31), and of whom it is written "the skin of his face shone," etc. (Exod. 34:29). [Some perceive the prophetic flash at long intervals; this is the degree of most prophets.] By others only once during the whole night is a flash of lightning perceived. This is the case with those of whom we are informed, "They prophesied, and did not prophesy again" (Num. 11:25). There are some to whom the flashes of lightning appear with varying intervals; others are in the condition of men, whose darkness is illumined not by lightning, but by some kind of crystal or similar stone, or other substances that possess the property of shining during the night; and to them even this small amount of light is not continuous, but now it shines and now it vanishes, as if it were "the flame of the rotating sword."
