that if a system of things and events exhibits perfection not here and there and at rare intervals but regularly, the inference is justified that there is an intelligent agent who had a definite purpose and design in establishing the system. The world below is such a system. Hence it has an intelligent agent as its author. This agent may be a separate and immaterial intelligence, or a corporeal power like a soul. He then shows that it cannot be a corporeal power, for it would have to reside in the animal sperm which exhibits such wonderful and purposive development, or in the parent animal from which the sperm came, both of which, he argues, are impossible. It remains then that the cause of the teleological life of the sublunar world is an immaterial power, a separate intellect. This intellect, he argues further, acts upon matter and endows it with forms, the only mediating power being the natural heat which is found in the seed and sperm of plants and animals. Moreover, it is aware of the order of what it produces. It is the Active Intellect of which we spoke above (p. 337). The forms of terrestrial things come from it directly, the heat residing in the seed comes from the motions of the spheres. This shows that the permanent motions of the heavenly bodies are also intelligent motions, for they tend to produce perfection in the terrestrial world and never come to a standstill, which would be the case if the motions were "natural" like those of the elements, or induced against their nature like that of a stone moving upward. We are justified in saying then that the heavenly bodies are endowed with intellects and have no material soul. Hence their movers are pure Intelligences, and there are as many of them as there are spheres, i. e., forty-eight, or fifty-eight or sixty-four according to one's opinion on the astronomical question of the number of spheres.
Now as the Active Intellect knows the order of sublunar existence in its unity, and the movers of the respective spheres know the order of their effects through the motions of the heavenly bodies, it follows that as all things in heaven above and on the earth beneath are related in a unitary system, there is a highest agent who is the cause of all existence absolutely and has a knowledge of all existence as a unitary system.350
The divine attributes are derived by us from his actions, and hence they are not pure homonyms (cf. p. 240). God has a knowledge of
