the change of Moses's rod into a serpent and of the water of Egypt into blood; of the latter, Moses's hand becoming leprous, and the withering of the hand of Jeroboam. We may further divide the mir- acles into those in which the prophet was told in advance, as Moses was of the ten plagues, and those in which he was not, as for example the reviving of the dead by Elijah and many other cases. Our examina- tion also shows us that all miracles are performed by prophets or in re- lation to them. Also that they are done with some good and useful purpose, namely, to inculcate behef or to save from evil.
These data will help us to decide who is the author of miracles. Miracles cannot be accidental, as they are performed with a purpose; and as they involve a knowledge of the sublunar order, they must have as their author one who has this knowledge, hence either God or the Active Intellect or man, i. e., the prophet himself. Now it is not reasonable to suppose that God is the author of miracles, for miracles come only rarely and are of no value in themselves but only as a means to a special end, as we said before. The laws of nature, however, which control all regular events all the time, are essentially good and permanent. Hence it is not reasonable to suppose that the Active Intellect who, as we know, orders the sublunar world, has more im- portant work to do than God. Besides if God were the author of miracles, the prophet would not know about them, for prophetic inspiration, as we know (p. 342), is due to the Active Intellect and not directly to God.
Nor do we need waste words in proving that man cannot be the author of miracles, for in that case the knowledge of them would not come to him through prophetic inspiration, since they are due to his own will. Besides man, as we have seen, cannot have a complete knowledge of the sublunar order, and hence it is not likely that he can control its laws to the extent of changing them.
There is therefore only one alternative left, namely, that the author of miracles is the same as the inspirer of the prophets, the controlling spirit of the sublunar world, whose intellect has as its content the unified system of sublunar creation as an immaterial idea, namely, the Active Intellect, of whom we have spoken so often. The prophet knows of the miracles because the Active Intellect, who is the author of them, is also the cause of the prophetic inspiration. This will
