Perfect knowledge of such things cannot be acquired without divine inspiration, given that all prophetic inspiration derives its initial origin from God Almighty, then from chance and nature. Since all these portents are produced impartially, prophecy comes to pass partly as predicted. For understanding created by the intellect cannot be acquired by means of the occult, only by the aid of the zodiac, bringing forth that small flame by whose light part of the future may be discerned. We need god to prosper those without him will not.
