This leads us to consider, more in detail, what sort of facts may be predicted according to the inspection of the positions occupied by the stars presiding over the birth of a man. They who, from the assertion that the stars indicate a man's future, draw the consequence that the stars produce them, are in error. In some person's horoscope which indicates birth from noble parents, on either maternal or paternal side, this nobility of birth cannot be attributed to the stars, as this nobility subsisted already in the parents before the stars had taken the position according to which the horoscope is cast. Besides, astrologers pretend they can discover the parent's fortune from the birth of their children, and from the condition of the parents the disposition and fate of the unborn offspring. From a child's horoscope, they announce his brother's death; and from a woman's horoscope, the fortunes of her husband, and conversely. It is unreasonable to refer to the stars things which evidently are necessary consequences of parental conditions. We then reach a dilemma: the cause lies either in these antecedent conditions, or in the stars. The beauty and ugliness of children, when they resemble their parents, must evidently be derived from them, and not from the course of the stars. Moreover, it is probable that at any one moment are born a crowd of human and animal young; now, inasmuch as they are born under the same star, they all ought to have the same nature. How does it then happen that, in the same positions, stars produce men and other beings simultaneously (as Cicero asks[105])? HEREDITY MORE IMPORTANT THAN STAR-INFLUENCE; CONTINUATION. 6. Each being derives his character from his nature. One being is a horse because he is born from a mare, while another is human, because born from a human mother; and more: he is that particular horse, and that particular man because he is born from such and such a horse, or woman. Doubtless, the course of the stars may modify the result, but the greatest part of the influence must be allowed to heredity. STARS AFFECT THE PHYSICAL, NOT THE MENTAL BEING. The stars act on the body only in a physical way, and thus impart to them heat, cold, and the variety of temperament which results therefrom. But how could they endow the man with habits, tastes, and inclinations which do not seem to depend on the temperament, such as the avocation of a surveyor, a grammarian, a gambler, or an inventor?
