How far Bacon let the principles of astrology carry him a citation or two will show. That a woman had succeeded in living twenty years without eating was, he explained, no miracle, but due to the fact that during that period some constellation was able to reduce the concourse of the four elements in her body to a greater degree of harmony than they usually attain.[28] Nor is it health alone that the stars control; they affect human character.[29] They implant in the babe at birth good or evil dispositions, great or small talents. Human free will may either better these innate tendencies through God’s grace or modify them for the worse by yielding to Satan’s temptings; but in general the stars so far prevail that there are different laws and customs and national traits under different quarters of the heavens.[30] Nay more, astrology offers proof of the superiority of Christianity to other religions and gives insight into the nature of Antichrist.[31] As one might surmise from Bacon’s belief in the potent effect of sidereal emanations, he makes much of the theory that every agent sends forth its own virtue and species into external matter. This leads him to accept fascination as a fact. Just as Aristotle tells that in some localities mares become pregnant by the mere odor of the stallions, and as Pliny relates that the basilisk kills by a glance, so the witch by the vapor from her bleary eye draws her victims on to destruction. In short, “Man can project virtue and species outside himself, the more since he is nobler than all corporeal things, and especially because of the virtue of the rational soul.”[32] Hence the great effects possible from spoken words or written characters; although one must beware of falling into the absurdities and abominations of the magicians. Bacon, moreover, was like Scot a believer in the doctrine of signatures.[33]
