Besides, not to speak of the inconclusive character of the philosophical arguments in favor of eternity and the positive arguments for creation (all or most of which we have already met in our previous studies, and need not therefore reproduce Aaron ben Elijah's version of them), the philosophers themselves without knowing it are led to contradict themselves in their very arguments from the assumption of eternity. The doctrine of creation follows as a consequence from their own presuppositions. Thus on the basis of eternity of motion they prove that the heavenly spheres are endowed with soul and intellect, and their motions are voluntary and due to conceptions which they endeavor to realize (cf. p. [267]). This makes the sphere a composite object, containing the elements, sphericity, soul, intellect. Everything composite is a possible existent, because its existence depends upon the existence of its parts. What is a possible existent may also not exist. Moreover, that which is possible must at some time become actual. Hence the sphere must at some time have been non-existent, and it required an agent to bring it into being. We are thus led to contradict our hypothesis of eternity from which we started.[365]
Creation is thus established, and this is the best way to prove the existence, unity and incorporeality of God. Maimonides attempts to prove creation from the peculiarities of the heavenly motions, which cannot be well accounted for on the theory of natural causes. Adopting the latter in the main, he makes an exception in the case of the spherical motions because the philosophers cannot adequately explain them, and jumps to the conclusion that here the philosophical appeal to mechanical causation breaks down and we are dealing with teleology, with intelligent design and purpose on the part of an intelligent agent. This leads to belief in creation. But this argument of Maimonides is very weak and inconclusive. Ignorance of causes in a special case, due to the limitations of our reason, proves nothing. Mechanical causes may be the sole determinants of the heavenly motions even though the philosophers have not yet discovered what they are (cf. above, p. [270 ff.]).[366]
Nor is Maimonides to be imitated, who bases his proof of the existence of God on the theory of eternity. The Bible is opposed to it. The Bible begins with creation as an indication that this is the basis of our knowledge of God's existence, revelation and providence. This is the method Abraham followed and this is what he meant when he swore by the "most high God, the creator of heaven and earth" (Gen. 14, 22). Abraham arrived at this belief through ratiocination and endeavored to convince others. The same thing is evident in the words of Isaiah (40, 26), "Lift up your eyes on high and see who created these." He was arguing with the people who believed in eternity, and proved to them the existence of God by showing that the world is created. All these indications in the Bible show that the doctrine of creation is capable of apodeictic proof.[367]
The reader will see that all this is directed against Maimonides, though he is not mentioned by name. Maimonides claimed against the Mutakallimun that it is not safe to base the existence of God upon the theory of creation, because the latter cannot be strictly demonstrated. And while he believed in it himself and gave reasons to show why it is more plausible than eternity, he admitted that others might think differently; and hence based his proofs of God's existence on the Aristotelian theory of eternity in order to be on the safe side. It is never too late to prove God's existence if the world is created. We must be sure of his existence, no matter what the fate of our cosmological theories might be. This did not appeal to the Karaite and Mutakallim, Aaron ben Elijah. His idea is that we must never for a moment doubt the creation of the world. To follow the procedure of Maimonides would have the tendency of making people believe that the world may be eternal after all, as happened in fact in the case of Gersonides. Aaron ben Elijah will not leave a way open to such a heresy.
In the doctrine of attributes Aaron ben Elijah likewise maintains the views of the Muʿtazilite Karaites against the philosophers, and especially against Maimonides. The general problem is sufficiently familiar to us by this time, and we need only present the salient points in the controversy. The question is whether there are any positive attributes which may be applied to God as actually denoting his essence—hence positive essential attributes. Maimonides denied it, the Karaites affirmed it. The arguments for Maimonides's denial we saw before (p. [262 f.]). And his conclusion is that the only attributes that may be applied to God are the negative, and those positive ones which do not denote any definite thing corresponding to them in God's essence, but are derived from the effects of God's unitary and simple being on the life of man and nature. He is the author of these effects, and we characterize him in the way in which we would characterize a human being who would do similar things; but this must not be done.
Aaron ben Elijah insists that there are positive essential attributes, which are the following five: Omnipotent, Omniscient, Acting with Will, Living, Existent. He agrees with Maimonides that these essential attributes must be understood in a manner not to interfere with God's simplicity and unity, but is satisfied that this can be done. For we must not conceive of them as additions to God's essence, nor as so many distinct elements composing God's essence, but as representing the multiplicity of powers issuing from him without detriment to his unity. We call them essential attributes, meaning that they are the essence of God, but not that they are different from each other and each makes up part of God's essence. We do not know God's essence, and these terms are simply transferred from our human experience, and do not indicate that God's activity can be compared to ours in any sense.
The five attributes above named are all identical with God's simple essence. "Living" denotes ability to perceive, hence is identical with "Omniscient." "Acting with will" likewise denotes just and proper action, which in turn involves true insight. Hence identity of will and knowledge. "Omnipotent" also in the case of an intellectual being denotes the act of the intellect par excellence, which is knowledge. And surely God's existence is not distinct from his essence, else his existence would be caused, and he would not be the necessary existent all agree him to be. It follows then that God is one, and his essence is nevertheless all these five attributes.
There are all the reasons in the world why we should apply attributes to God. The same reason as we have for applying names to anything else exists for giving names to God. In fact it would be correct to say that we should have more names for God than for anything else, since in other things we can avoid naming them by pointing to them, as they can be perceived by the senses. Not so God. We are forced to use words in talking about him. God has given himself names in the Bible, hence we may do the same.
Maimonides and his school endeavor to obviate the criticisms of the philosophers, who are opposed to all attributes, by excluding all but negative terms. But this does not help the matter in the least. A negative attribute is in reality no different from a positive, and in the end leads to a positive. Thus if we say "not mineral," "not plant," we clearly say "animal." The advocates of negative attributes answer this criticism by saying that they understand pure negation without any positive implications, just as when we say a stone is "not seeing," we do not imply that it is blind. But this cannot be, for when they say God is "not ignorant," they do not mean that he is not "knowing" either, for they insist that he is power and knowledge and life, and so on. This being the case, it is much more proper to use positive attributes, seeing that the Prophets do so. When they say that the Prophets meant only to exclude the negative; that by saying, "Able," "Knowing," they meant to exclude "weak" "ignorant," they ipso facto admit that by excluding the latter we posit the former.
The arguments against positive essential attributes we can easily answer. By saying that certain attributes are essential we do not claim to know God's essence. All we know is God's existence, which we learn from his effects, and according to these same effects we characterize God's existence by means of attributes of which also we know only the existence, not the essence. For we do not mean to indicate that these terms denote the same thing in God as they denote in us. They are homonyms, since in God they denote essence, whereas in us they are accidents. The plurality of attributes does not argue plurality in God, for one essence may perform a great many acts, and hence we may characterize the essence in accordance with those acts. The error of composition arises only if we suppose that the various acts point to various elements in their author. Of the various kinds of terms those only are applicable to God which denote pure essence or substance like knowledge, power; and those denoting activity like creating, doing, and so on.[368]
