16. Now let us look at our second undertaking, and try to show how it is that the stars cannot be causative, though they may possibly be indicative. In the vast multitude of nativities we may possibly get at the incidents of one man's life; but this is only an assumption; we concede the point that it is possible for men to gain a knowledge of them. For instance, our opponents say we may learn both from a man's own nativity, and from the nativity of each of his brothers, if he has more than one, that he will suffer in a certain way, and will die a violent death through meeting with robbers. For they suppose that the nativity of each one includes the death of a brother at the hand of robbers, and likewise the nativity of the father and mother and wife and sons and domestics and dearest friends, and perhaps the nativity of the murderers themselves. How can a man then, whose future is involved in so many nativities, to make them this concession, be influenced by the position and relation of the stars at one nativity more than by those at the others? The statement that the position of the stars at a man's own nativity has caused certain events, while their position at the nativities of the rest has not caused but only indicated them, is incredible; and it is as silly to say that the nativity of each one of them, severally, included a cause of the violent death of this one in particular, so that in fifty nativities, suppose, is included the death of this one person. I do not know how they will maintain that the position of the stars at the nativity of nearly everybody in Judea |190 was such that they received circumcision on the eighth day, being mutilated in their parts, and ulcerated, and subject to inflammation and sores, and no sooner born than needing a doctor; while the position at the nativity of certain Israelites down in Arabia was such that they were all circumcised at the age of thirteen years, for this is what we are told about them; and again the position at the nativity of certain people in Etheopia such that they had their knee-pans taken away, while the Amazons had one of their breasts removed. How do the stars cause these effects in various nations? I suppose that if we give close attention to the subject, we shall not be able to state a single true and reliable fact about these things. And when we hear of so many ways of knowing the future, I am at a loss to understand how men can be so inconsistent as to deny the existence of an active cause in augury, and in sacrificial inspection, maintaining that they are only indicative, but will not allow that astrology also, and nativity casting, are only indicative. For if because a future event is known,----granting that it is known,----the source of the event is the same as the source of the knowledge, why shall events any more be caused by stars than by birds, and by birds, or by entrails of victims, more than by ruling stars? This will suffice for the present to upset the notion that the stars are causes of human affairs.
