Whether Astrology is of any Value.[198]
OF THE INFLUENCE OF THE STARS.
1. It has been said[199] that the course of the stars indicates what is to happen to each being; though, it does not, as many persons think, cause every event. To the supporting proofs hereof we are to add now more precise demonstrations, and new considerations, for the opinion held about this matter is no trifle.
VARIOUS PRETENSIONS OF ASTROLOGY.
Some people hold that, by their movements, the planets produce not only poverty and wealth, health and sickness, but even beauty and ugliness; and, what is more, vices and virtues. At every moment the stars, as if they were irritated against men, (are said to) force them to commit actions concerning which no blame attaches to the men who commit them, since they are compelled thereto by the influence of the planets. It is even believed that the cause of the planets' doing us evil or good is not that they love or hate us; but that their dispositions towards us is good or evil according to the localities through which they travel. Towards us they change their disposition according as they are on the cardinal points or in declination therefrom. It is even held that while certain stars are maleficent, others are beneficent, and that, nevertheless, the former frequently grant us benefits, while the latter often become harmful. Their effects differ according to their being in opposition,[200] just as if they were not self-sufficient, and as if their quality depended on whether or not they looked at each other. Thus a star's (influence) may be good so long as it regards another, and evil when it does so no longer. A star may even consider another in different manners,[201] when it is in such or such an aspect.[202] Moreover, the totality of the stars exercises a mingled influence which differs from the individual influences, just as several liquors may form a compound possessing qualities differing from either of the component elements. As these and similar assertions are freely made, it becomes important to examine each one separately. This would form a proper beginning for our investigation.
ARE STARS INANIMATE?
2. Should we consider the stars to be animated, or not? If they be inanimate, they will be able to communicate only cold and heat; that is, if[203] we grant the existence of cold influences. In this case, they will limit themselves to modifying the nature of our body, exercising on us a merely corporeal influence. They will not produce a great diversity among the bodies, since each of them exercises the same influence, and since, on the earth, their diverse actions are blended into a single one, which varies only by the diversity of locality, or by the proximity or distance of the objects. The same argument would hold on the hypothesis that the stars spread cold. But I could not understand how they could render some learned, others ignorant, making of some grammarians, others orators, musicians or experts in various arts. How could they exercise an action which would have no relation to the constitution of the bodies, such as giving us a father, a brother, a son, or a wife of such or such characteristics, or to make us successful, or make of us generals or kings?[204]
ARE STARS ANIMATED?
On the contrary hypothesis, that the stars are animated, and act with reflection, what have we done to them that they should desire to harm us? Are they not dwellers of a divine region? Are they not themselves divine? Nor are they subjected to the influences that make men good or evil, nor could they experience good or evil as a result of our prosperity or our misfortunes.
