Mutakallemim, in order to prove the act of creation, imply an order of things contrary to that which really exists, and involve a complete change in the laws of nature; this fact will be pointed out to you, for it will be necessary to mention their propositions and their argumentation. My method, as far as I now can explain it in general terms, is as follows. The universe is either eternal or has had a beginning; if it had a beginning, there must necessarily exist a being which caused the beginning; this is clear to common sense; for a thing that has had a beginning, cannot be the cause of its own beginning, another must have caused it. The universe was, therefore, created by God. If on the other hand the universe were eternal, it could in various ways be proved that apart from the things which constitute the universe, there exists a being which is neither body nor a force in a body, and which is one, eternal, not preceded by any cause, and immutable. That being is God. You see that the proofs for the Existence, the Unity and the Incorporeality of God must vary according to the propositions admitted by us. Only in this way can we succeed in obtaining a perfect proof, whether we assume the eternity or the creation of the universe. For this reason you will find in my works on the Talmud, whenever I have to speak of the fundamental principles of our religion, or to prove the existence of God, that I employ arguments which imply the eternity of the universe. I do not believe in that eternity, but I wish to establish the principle of the existence of God by an indisputable proof, and should not like to see this most important principle founded on a basis which every one could shake or attempt to demolish, and which others might consider as not being established at all; especially when I see that the proofs of the philosophers are based on those visible properties of things, which can only be ignored by persons possessing certain preconceived notions, while the Mutakallemim establish their arguments on propositions which are to such an extent contrary to the actual state of things as to compel these arguers to deny altogether the existence of the laws of nature. When I shall have to treat of the creation, I shall in a special chapter prove my opinion to some extent, and shall attain the same end which every one of the Mutakallemim had in view, yet I shall not contradict the laws of nature, or reject any such part of the Aristotelean theory as has been proved to be correct. Even the most cogent of the proofs offered by the Mutakallemim respecting the act of creation, has only been obtained by reversing the whole order of things and by rejecting everything fully demonstrated by the philosophers. I, however, shall be able to give a similar proof without ignoring the laws of nature and without being forced to contradict facts which have been clearly perceived. I find it necessary to mention to you the
