The first and the fourth arguments may be termed cosmological proofs. They are based on the hypothesis that the series of causes for every change is finite, and terminates in the Primal Cause. There is no essential difference in the two arguments: in the first are discussed the causes of the motion of a moving object; the fourth treats of the causes which bring about the transition of a thing from potentiality to reality. To prove that neither the spheres nor a force residing in them constitute the Primal Cause, the philosophers employed two propositions, of which the one asserts that the revolutions of the spheres are infinite, and the other denies the possibility that an infinite force should reside in a finite object. The distinction between the finite in space and the finite in time appears to have been ignored; for it is not shown why a force infinite in time could not reside in a body finite in space. Moreover, those who, like Maimonides, reject the eternity of the universe, necessarily reject this proof, while those who hold that the universe is eternal do not admit that the spheres have ever been only potential, and passed from potentiality to actuality. The second argument is supported by the following supplementary proposition: If two elements coexist in a state of combination, and one of these elements is to be found at the same time separate, in a free state, it is certain that the second element is likewise to be found by itself. Now, since things exist which combine in themselves motive power and mass moved by that power, and since mass is found by itself, motive power must also be found by itself independent of mass.
The third argument has a logical character: The universe is either eternal or temporal, or partly eternal and partly temporal. It cannot be eternal in all its parts, as many parts undergo destruction; it is not altogether temporal, because, if so, the universe could not be reproduced after being destroyed. The continued [[l]]existence of the universe leads, therefore, to the conclusion that there is an immortal force, the Primal Cause, besides the transient world.
These arguments have this in common, that while proving the existence of a Primal Cause, they at the same time demonstrate the Unity, the Incorporeality, and the Eternity of that Cause. Special proofs are nevertheless superadded for each of these postulates, and on the whole they differ very little from those advanced by the Mohammedan Theologians.
This philosophical theory of the Primal Cause was adapted by Jewish scholars to the Biblical theory of the Creator. The universe is a living, organized being, of which the earth is the centre. Any changes on this earth are due to the revolutions of the spheres; the lowest or innermost sphere, viz., the one nearest to the centre, is the sphere of the moon; the outermost or uppermost is “the all-encompassing sphere.” Numerous spheres are interposed; but Maimonides divides all the spheres into four groups, corresponding to the moon, the sun, the planets, and the fixed stars. This division is claimed by the author as his own discovery; he believes that it stands in relation to the four causes of their motions, the four elements of the sublunary world, and the four classes of beings, viz., the mineral, the vegetable, the animal, and the rational. The spheres have souls, and are endowed with intellect; their souls enable them to move freely, and the impulse to the motion is given by the intellect in conceiving the idea of the Absolute Intellect. Each sphere has an intellect peculiar to itself; the intellect attached to the sphere of the moon is called “the active intellect” (Sekel ha-poʻēl). In support of this theory numerous passages are cited both from Holy Writ and from post-Biblical Jewish literature. The angels (elohim, malakim) mentioned in the Bible are assumed to be identical with the intellects of the spheres; they are free agents, and their volition invariably tends to that which is good and noble; they emanate from the Primal Cause, and form a descending series of beings, ending with the active intellect. The transmission of power from one element to the other is called “emanation” (shefaʻ). This transmission is performed without the utterance of a sound; if any voice is supposed to be heard, it is only an illusion, originating in the human imagination, which is the source of all evils (ch. xii.).
In accordance with this doctrine, Maimonides explains that the three men who appeared to Abraham, the angels whom Jacob saw ascend and descend the ladder, and all other angels seen by man, are nothing but the intellects of the spheres, four in number, which emanate from the Primal Cause (ch. x.). In his description of the spheres he, as usual, follows Aristotle. The spheres do not contain any of the four elements of the sublunary world, but consist of a quintessence, an entirely different element. Whilst things on this earth are transient, the beings which inhabit the spheres above are eternal. According to Aristotle, these spheres, as well as their intellects, coexist with the Primal Cause. Maimonides, faithful to the teaching of the Scriptures, here departs from his master, and holds that the spheres and the intellects had a beginning, and were brought into existence by the will of the Creator. He does not attempt to give a positive proof of his doctrine; all he contends is that the theory of the creatio ex nihilo is, from a philosophical point of view, not inferior to the doctrine which asserts the eternity of the universe, and that he can refute all objections advanced against his theory (ch. xiii.–xxviii.).
He next enumerates and criticises the various theories respecting the origin of the Universe, viz.: A. God created the Universe out of nothing. B. God formed the Universe from an eternal substance. C. The Universe originating in the eternal Primal Cause is co-eternal.—It is not held necessary by the author to discuss the view of those who do not assume a Primal Cause, since the existence of such a cause has already been proved (ch. xiii.). [[li]]
The objections raised to a creatio ex nihilo by its opponents are founded partly on the properties of Nature, and partly on those of the Primal Cause. They infer from the properties of Nature the following arguments: (1) The first moving force is eternal; for if it had a beginning, another motion must have produced it, and then it would not be the First moving force. (2) If the formless matter be not eternal, it must have been produced out of another substance; it would then have a certain form by which it might be distinguished from the primary substance, and then it would not be formless. (3) The circular motion of the spheres does not involve the necessity of termination; and anything that is without an end, must be without a beginning. (4) Anything brought to existence existed previously in potentia; something must therefore have pre-existed of which potential existence could be predicated. Some support for the theory of the eternity of the heavens has been derived from the general belief in the eternity of the heavens.—The properties of the Primal Cause furnished the following arguments:—If it were assumed that the Universe was created from nothing, it would imply that the First Cause had changed from the condition of a potential Creator to that of an actual Creator, or that His will had undergone a change, or that He must be imperfect, because He produced a perishable work, or that He had been inactive during a certain period. All these contingencies would be contrary to a true conception of the First Cause (ch. xiv.).
Maimonides is of opinion that the arguments based on the properties of things in Nature are inadmissible, because the laws by which the Universe is regulated need not have been in force before the Universe was in existence. This refutation is styled by our author “a strong wall built round the Law, able to resist all attacks” (ch. xvii.). In a similar manner the author proceeds against the objections founded on the properties of the First Cause. Purely intellectual beings, he says, are not subject to the same laws as material bodies; that which necessitates a change in the latter or in the will of man need not produce a change in immaterial beings. As to the belief that the heavens are inhabited by angels and deities, it has not its origin in the real existence of these supernatural beings; it was suggested to man by meditation on the apparent grandeur of heavenly phenomena (ch. xviii.).
Maimonides next proceeds to explain how, independently of the authority of Scripture, he has been led to adopt the belief in the creatio ex nihilo. Admitting that the great variety of the things in the sublunary world can be traced to those immutable laws which regulate the influence of the spheres on the beings below—the variety in the spheres can only be explained as the result of God’s free will. According to Aristotle—the principal authority for the eternity of the Universe—it is impossible that a simple being should, according to the laws of nature, be the cause of various and compound beings. Another reason for the rejection of the Eternity of the Universe may be found in the fact that the astronomer Ptolemy has proved the incorrectness of the view which Aristotle had of celestial spheres, although the system of that astronomer is likewise far from being perfect and final (ch. xxiv.). It is impossible to obtain a correct notion of the properties of the heavenly spheres; “the heaven, even the heavens, are the Lord’s, but the earth hath He given to the children of man” (Ps. cxv. 16). The author, observing that the arguments against the creatio ex nihilo are untenable, adheres to his theory, which was taught by such prophets as Abraham and Moses. Although each Scriptural quotation could, by a figurative interpretation, be made to agree with the opposite theory, Maimonides declines to ignore the literal sense of a term, unless it be in opposition to well-established truths, as is the case with anthropomorphic expressions; for the latter, if taken literally, would be contrary to the demonstrated truth of God’s incorporeality (ch. xxv.). He is therefore surprised that the author of Pirke-di Rabbi Eliezer ventured to assume the eternity of [[lii]]matter, and he thinks it possible that Rabbi Eliezer carried the license of figurative speech too far. (Ch. xxvi.).
The theory of the creatio ex nihilo does not involve the belief that the Universe will at a future time be destroyed; the Bible distinctly teaches the creation, but not the destruction of the world except in passages which are undoubtedly conceived in a metaphorical sense. On the contrary, respecting certain parts of the Universe it is clearly stated “He established them for ever.” (Ps. cxlviii. 5.) The destruction of the Universe would be, as the creation has been, a direct act of the Divine will, and not the result of those immutable laws which govern the Universe. The Divine will would in that case set aside those laws, both in the initial and the final stages of the Universe. Within this interval, however, the laws remain undisturbed (ch. xxvii.). Apparent exceptions, the miracles, originate in these laws, although man is unable to perceive the causal relation. The Biblical account of the creation concludes with the statement that God rested on the seventh day, that is to say, He declared that the work was complete; no new act of creation was to take place, and no new law was to be introduced. It is true that the second and the third chapters of Genesis appear to describe a new creation, that of Eve, and a new law, viz., that of man’s mortality, but these chapters are explained as containing an allegorical representation of man’s psychical and intellectual faculties, or a supplemental detail of the contents of the first chapter. Maimonides seems to prefer the allegorical explanation which, as it seems, he had in view without expressly stating it, in his treatment of Adam’s sin and punishment. (Part I. ch. ii.) It is certainly inconsistent on the one hand to admit that at the pleasure of the Almighty the laws of nature may become inoperative, and that the whole Universe may become annihilated, and on the other hand to deny, that during the existence of the Universe, any of the natural laws ever have been or ever will be suspended. It seems that Maimonides could not conceive the idea that the work of the All-wise should be, as the Mutakallemim taught—without plan and system, or that the laws once laid down should not be sufficient for all emergencies.
