IRRATIONAL CLAIMS OF ASTROLOGERS.
Besides, nobody would admit that perversity could come from beings who are divinities. How could one believe that they are the authors of the evils attributed to them, and that they themselves become evil because they set or pass under the earth, as if they could possibly be affected by the fact that, in regard to us, they seem to set; as if they did not continue to wander around the heavenly sphere, and remained in the same relation to the earth? Besides it is incredible that because a star is in such or such a position in respect of another star, it becomes better or worse, and that it affects us with goodness when it is well disposed, and evil in the contrary case. STARS SERVE AS LETTERS IN WHICH TO READ NATURE. We grant that by their movement the stars co-operate in the conservation of the universe, and that they simultaneously play in it another part. They serve as letters for those skilled in deciphering this kind of writing; and who, by the observation of the figures formed by the stars, read into them future events according to the laws of analogy, as for instance, if one presaged high deeds from seeing a bird fly high. 7. There remains to be considered the (Stoic) doctrine which, concatenating and interrelating all things among each other, establishes "a single cause which produces everything through seminal reasons." This doctrine reattaches itself to (Heraclitus's) which deduces from the action of the universal Soul the constitution and the movements of the individuals as well as those of the universe.
