Note.—It was not my intention when writing this treatise to expound natural science or discuss metaphysical systems; it was not my object to prove truths which have already been demonstrated, or describe the number and the properties of the spheres: for the books written on these subjects serve their purpose, and if in some points they are not satisfactory, I do not think that what I could say would be better than what has already been explained by others. But my intention was, as has been stated in the Introduction, to expound Biblical passages which have been impugned, and to elucidate their hidden and true sense, which is above the comprehension of the multitude. When you therefore notice that I prove the existence and number of Intelligences or the number of the spheres, with the causes of their motion, or discuss the true relation of matter and form, the meaning of Divine manifestation, or similar subjects, you must not think that I intend merely to establish a certain philosophical proposition; for these subjects have been discussed in many books, and most of them have been demonstrated by proof. I only desire to mention that which might, when well understood, serve as a means of removing some of the doubts concerning anything taught in Scripture; and indeed many difficulties will disappear when that which I am about to explain is taken into consideration. From the Introduction to this treatise you may learn that its principal object is to expound, as far as can be done, the account of the Creation (Gen. i.-iii.), and of the Divine Chariot (Ezek. i.), and to answer questions raised in respect to Prophecy and to the knowledge of God. You will sometimes notice that I am rather explicit on truths already ascertained; some of them Natural Philosophy has established as facts; others Metaphysics has either fully demonstrated, or at least shown to be worthy of belief; others Mathematics have made plain. But you will invariably find that my exposition includes the key for the understanding of some allegorical passage of Holy Writ and its esoteric interpretation, and that I have mentioned, explained, and demonstrated the subject only because it [[156]]furthers the knowledge of the “Divine Chariot,” or “the Creation,” or explains some principle with respect to Prophecy, or to the belief in any of the truths taught in Scripture. Now, having made this statement, we return to the subject of which we began to treat.
CHAPTER III
The theory of Aristotle in respect to the causes of the motion of the spheres led him to assume the existence of Intelligences. Although this theory consists of assertions which cannot be proved, yet it is the least open to doubt, and is more systematic than any other, as has been stated by Alexander in the book called The Origin of the Universe. It includes maxims which are identical with those taught in Scripture, and it is to a still greater extent in harmony with doctrines contained in well-known genuine Midrashim, as will be explained by me. For this reason I will cite his views and his proofs, and collect from them what coincides with the teachings of Scripture, and agrees with the doctrine held by our Sages.
CHAPTER IV
The enunciation that the heavenly sphere is endowed with a soul will appear reasonable to all who sufficiently reflect on it; but at first thought they may find it unintelligible or even objectionable; because they wrongly assume that when we ascribe a soul to the heavenly spheres we mean something like the soul of man, or that of an ass, or ox. We merely intend to say that the locomotion of the sphere undoubtedly leads us to assume some inherent principle by which it moves; and this principle is certainly a soul. For it would be absurd to assume that the principle of the circular motion of the spheres was like that of the rectilinear motion of a stone downward or of fire upwards, for the cause of the latter motion is a natural property and not a soul; a thing set in motion by a natural property moves only as long as it is away from the proper place of its element, but when it has again arrived there, it comes to rest; whilst the sphere continues its circular motion in its own place. It is, however, not because the sphere has a soul, that it moves in this manner; for animate beings move either by instinct or by reason. By “instinct” I mean the intention of an animal to approach something agreeable, or to retreat from something disagreeable; e.g., to approach the water it seeks because of thirst, or to retreat from the sun because of its heat. It makes no difference whether that thing really exists or is merely imaginary, since the imagination of something agreeable or of something disagreeable likewise causes the animal to move. The heavenly sphere does not move for the purpose of withdrawing from what is bad or approaching what is good. For in the first instance it moves toward the same point from which it has moved away, and vice versâ it moves away from the same point towards which it has moved. Secondly, if this were the object of the motion, we should expect that the sphere would move towards a certain point, and would then rest; for if it moved for the purpose of avoiding something, and never obtained that object, the motion would be in vain. The circular motion of the sphere is consequently due to the action of [[157]]some idea which produces this particular kind of motion; but as ideas are only possible in intellectual beings, the heavenly sphere is an intellectual being. But even a being that is endowed with the faculty of forming an idea, and possesses a soul with the faculty of moving, does not change its place on each occasion that it forms an idea; for an idea alone does not produce motion, as has been explained in [Aristotle’s] Metaphysics. We can easily understand this, when we consider how often we form ideas of certain things, yet do not move towards them, though we are able to do so; it is only when a desire arises for the thing imagined, that we move in order to obtain it. We have thus shown that both the soul, the principle of motion, and the intellect, the source of the ideas, would not produce motion without the existence of a desire for the object of which an idea has been formed. It follows that the heavenly sphere must have a desire for the ideal which it has comprehended, and that ideal, for which it has a desire, is God, exalted be His name! When we say that God moves the spheres, we mean it in the following sense: the spheres have a desire to become similar to the ideal comprehended by them. This ideal, however, is simple in the strictest sense of the word, and not subject to any change or alteration, but constant in producing everything good, whilst the spheres are corporeal; the latter can therefore not be like this ideal in any other way, except in the production of circular motion; for this is the only action of corporeal beings that can be perpetual; it is the most simple motion of a body; there is no change in the essence of the sphere, nor in the beneficial results of its motion.
When Aristotle had arrived at this result, he further investigated the subject, and found, by proof, that there were many spheres, and that all moved in circles, but each with its peculiar motion as regards velocity and direction. He naturally argued that the ideal comprehended by the one sphere, which completes its circuit in one day, is different from that of another sphere which completes its circuit in thirty years; he thus arrived at the conclusion that there were as many ideals as there were spheres; each sphere has a desire for that ideal which is the source of its existence, and that desire is the cause of its individual motion, so that in fact the ideal sets the sphere in motion. Aristotle does not say, nor does any other authority, that there are ten or a hundred ideals; he simply states that their number agrees with that of the spheres. When, therefore, some of his contemporaries held that the number of spheres was fifty, he said, if that was true, the number of ideals must likewise be fifty. For the scholars in his time were few and possessed but imperfect learning; they thought that there must be a separate sphere for each movement, because they did not know that what appear to be several distinct movements can be explained as resulting from the inclination of one sphere as is, e.g., the case with the change in the longitude of a star, its declination and the places of its rising and setting noticed in the circle of the horizon. This point, however, does not concern us at present; let us therefore return to our subject.
The later philosophers assumed ten Intelligences, because they counted the spheres containing stars and the all-encompassing sphere, although some of the spheres included several distinct orbits. There are altogether nine spheres, viz., the all-encompassing sphere, that of the fixed stars, and those of the seven planets; nine Intelligences correspond to the nine spheres; [[158]]the tenth Intelligence is the Active Intellect. The existence of the latter is proved by the transition of our intellect from a state of potentiality to that of actuality, and by the same transition in the case of the forms of all transient beings. For whatever passes from potentiality into actuality, requires for that transition an external agent of the same kind as itself. Thus the builder does not build the storehouse in his capacity of workman, but in that of a person that has the form of the storehouse in his mind; and that form of the building which exists in the mind of the builder caused the transition of the potential form of the storehouse into actuality, and impressed it on the material of the building. As that which gives form to matter must itself be pure form, so the source of intellect must itself be pure intellect, and this source is the Active Intellect. The relation of the latter to the elements and their compounds is the same as that of the Intelligences to their respective spheres; and our intellect in action, which originates in the Active Intellect, and enables us to comprehend that intellect, finds a parallel in the intellect of each of the spheres which originates in the Intelligence corresponding to that sphere, and enables the sphere to comprehend that Intelligence, to form an idea of it, and to move in seeking to become similar to it.
Aristotle further infers, what has already been explained, that God does not act by means of direct contact. When, e.g., He destroys anything with fire, the fire is set in motion through the movement of the spheres, and the spheres by the Intelligences; the latter, which are identical with “the angels,” and act by direct influence, are consequently, each in its turn, the cause of the motion of the spheres; as however, purely spiritual beings do not differ in their essence, and are by no means discrete quantities, he (Aristotle) came to the following conclusion: God created the first Intelligence, the motive agent of the first sphere; the Intelligence which causes the second sphere to move has its source and origin in the first Intelligence, and so on; the Intelligence which sets the sphere nearest to the earth in motion is the source and origin of the Active Intellect, the last in the series of purely spiritual beings. The series of material bodies similarly begins with the uppermost sphere, and ends with the elements and their compounds. The Intelligence which moves the uppermost sphere cannot be the Absolute Being, for there is an element common to all Intelligences, namely, the property of being the motive agent of a sphere, and there is another element by which each of them is distinguished from the rest; each of the ten Intelligences includes, therefore, two elements, and consequently another being must be the First Cause.
