But I would reply that it is nevertheless true that—admitting such a hypothesis—the Sun would still give off these qualities mentioned, for they are formal to the Sun and active even to a great distance, causing the heating and illumination of the earth; however, these effects are not celestial but elemental, and in conformity with the nature of fire. But the Sun does not have an influence on earth, or any animal born on it, except very generally, but not specifically—as on the health, profession, etc.— because no such specific influence exists except that which is brought about through house-location in the horoscope; and the influence of the stars always comes through these houses.One might argue that the primary houses which condition this influence are nothing other than a division of the entire space surrounding earth, and on earth are—or can be conceived of as—the poles, axis, and equator by which that space is divided; and in this way the influence of the Sun or a planet is to be admitted.I would reply that there is no active influence through the primary houses, which are nothing other than empty space and therefore inactive, but there is rather a determinative influence through them. But in fact we showed earlier that the system of sign division has an active influence not only with the planets but also by itself, such as when the various signs appear on the Ascendant or in the other houses. The signs, however, are not parts of immobile space since they themselves are moveable through the primary houses or spaces; nor are they parts of the earth because the earth is also immobile and therefore without poles, axis, or equator. In fact, the signs are those parts of the primum caelum which were determined by the planets at creation—that is, first causes from secondary ones. Since they now have a simultaneous influence, as a first and second cause of the same effect which is necessarily dependent on each, it follows that the stars are not able to exert a specific influence without the cooperation of the primum caelum, although they are able to give off light and heat.
