Because just as the experienced physician is able to preserve the bodies of men from the aforementioned threatening deaths, so the astrologer is able to avert many things that are going to happen according to the significations of the stars, which, if they were not known, would be the causes from which many harmful things would accompany man.
And science is an accident 1 such that, the more it is increased in man, the more it removes him from the other animals; and on account of this, which is the soul of science, he is made more worthy and more noble than they, as also by discretion and by the cognition of things which have been, which are, and which will be.
