The Name of the Rose

by Umberto Eco

“You can certainly speak of magic in this device,” William allowed. “But there are two forms of magic. There is a magic that is the work of the Devil and which aims at man’s downfall through artifices of which it is not licit to speak. But there is a magic that is divine, where God’s knowledge is made manifest through the knowledge of man, and it serves to transform nature, and one of its ends is to prolong man’s very life. And this is holy magic, to which the learned must devote themselves more and more, not only to discover new things but also to rediscover many secrets of nature that divine wisdom had revealed to the Hebrews, the Greeks, to other ancient peoples, and even, today, to the infidels (and I cannot tell you all the wonderful things on optics and the science of vision to be read in the books of the infidels!). And Christian knowledge must regain possession of all this learning, taking it from the pagans and infidels tamquam ab iniustis possessoribus, as they had no right to hold it.”
