From the Intelligence of the lunar sphere emanated the Active Intellect and the sublunar spheres of the four elements.
Hence it is absurd to speak of God as an element of the sublunar world.
But Aristotle's method breaks down the moment he leaves the sublunar sphere.
It is called the Active Intellect, and its business is to govern the sublunar world of generation and decay.
God put in sublunar matter the nature and capacity of receiving all forms in a certain order.
The lower world, the sublunar and corporeal world of generation and decay, was created in time.
The general process of the sublunar world is that of genesis and dissolution.
Our answer is that the definition represents that unitary aspect of the sublunar individuals which is in the Active Intellect.
It remains then that the cause of the teleological life of the sublunar world is an immaterial power, a separate intellect.
God has a knowledge of the complete order of sublunar things, of which the several movers have only a part.
