of the view of the philosophers on this point. But it cannot be accepted by those who admit the existence of divine attributes. For according to their opinion, the Primal Cause includes many different elements. They represent its wisdom and its omnipotence as two different things, and again the omnipotence as different from the will. Consequently it would not be impossible that either of the two divine beings possessed several properties, some of which would be common to both, and some peculiar to only one of them.
Third Argument.
This argument is likewise based on one of the Propositions of the Kalam. For some of the Mutakallemim belonging to the old school assume, that when the Creator wills a thing, the will is not an element superadded to the essence of God: it is a will without a substratum. In accordance with the propositions which we have mentioned, and of which, as you will see, it is difficult to form a true conception, they say that one will, which is independent of any substratum, cannot be ascribed to two beings: for, as they assert, one cause cannot be the source of two laws for two essences. This is, as I told you, the method of explaining one difficulty by means of another and still greater difficulty. For as they define the Will, it is inconceivable, and some have, therefore, considered it to be a mere non-entity: others who admit its existence, meet with many insuperable difficulties. The Mutakallemim, nevertheless, establish on its existence one of the proofs for the unity of God.
Fourth Argument.
The existence of an action is necessarily positive evidence of the existence of an agens, but does not prove the existence of more than one agens. There is no difference whether the existence of one God be assumed or the existence of two, or three, or twenty, or any number. This is plain and clear. But the argument does not seem to prove the non-existence of a multitude of deities; it only shows that their number is unknown; the deity may be one sole being, but may also include several divine beings. The following supplemental argument has therefore been advanced: possibility is inapplicable to the existence of God, which is absolute: the possibility of the existence of more than one God must therefore be denied. This is the whole essence of the proof, and its fallacy is self-evident; for although the notion of possibility cannot be applied to the existence of God, it can be applied to our knowledge of God: for an alternative in our knowledge of a thing does not involve an alternative in the actual existence of the thing, and perhaps there is neither a tripartite deity as the Christians believe, nor an undivided Unity as we believe. This is clear to those who have been taught to notice the conclusions implied in given premises.
Fifth Argument.
One of the modern Mutakallemim thought that he found a proof of the Unity of God in the idea of requisiteness. Suppose there were two divine beings; if one of them were able to create the universe, the second God would be superfluous, and there would be no need for his existence. If, on the other hand, the entire universe could not be created or governed except by
