Most Christians are aware of C.S. Lewis and a fortunate subset have actually read one or a few of his works, perhaps The Chronicles of Narnia or Mere Christianity or The Screwtape Letters. His signature appeal is a capacity to describe experiences outside of our natural world. A drab grey town that’s infinitesimally small and diminishing but ever growing at the same time, where Napoleon lives by himself in an ever-more remote mansion, pacing about and ranting against his enemies. A quiet green wood with pools that are portals to other worlds. Merlin awakened from his tomb in the modern day as a servant of God, wielding angelic power to destroy an evil “scientific” organization directed by a demonically animated severed human head.
Most people call this imagination, and it absolutely is. But it’s much more. Lewis taught Medieval literature at Oxford and Cambridge. He knew what great thinkers throughout history said. Reportedly he had a photographic memory. His true gift was not inventing new concepts but rather translating the great thoughts from the past for us moderns in a way that we can understand and enjoy.
What precipitated this post was reading this footnote in Perelandra where Lewis explains that the idea of angels and demons existing in multidimensional space—a key point in his The Space Trilogy—originated with a 17th century scholar.
The footnote is here, the same as shown in the attached photo, in place of alt-text:
1. In the text I naturally keep to what I thought and felt at the time, since this alone is first-hand evidence: but there is obviously room for much further speculation about the form in which eldila appear to our senses. The only serious considerations of the problem so far are to be sought in the early seventeenth century. As a starting point for future investigation I recommend the following from Natvilcius (De Aethereo at aerio Corpore, Basel. I627, II. xii.); liquet simplicem flammam sensibus nostris subjectam non esse corpus proprie dictum angeli vel daemonis, sed potius aut illius corporis sensorium aut superficiem corporis in coelesti dispositione locorum supra cogitationes humanas existentis. ("It appears that the homogeneous flame perceived by our senses is not the body, properly so called, of an angel or daemon, but rather either the sensorium of that body or the surface of a body which exists after a manner beyond our conception in the celestial frame of special references.") By the "celestial frame of references" I take him to mean what we should now call "multi-dimensional space." Not, of course, that Natvilcius knew anything about multidimensional geometry, but that he had reached empirically what mathematics has since reached on theoretical grounds.
