1. There is some difference between astronomy and astrology.
For astronomy embraces the revolution of the heavens, the rise,
setting, and motion of the heavenly bodies, and the origin of their
names. Astrology, on the other hand, is in part natural, in part
superstitious.
2. It is natural astrology when it describes the courses of the
sun and the moon and the stars, and the regular succession of the
seasons. Superstitious astrology is that which the mathematici
follow, who prophesy by the stars, and who distribute the twelve
signs of the heavens among the individual parts of the soul or body,
and endeavor to predict the nativities and characters of men from the
course of the stars.
