It’s true that all those exclamation marks don’t seem Lewisian (if that’s a word); so maybe that great quote was penned by someone else.
I readily believed it, because I just so happen to be halfway through That Hideous Strength, which, though published in 1945, eerily foretells what’s happening now (the technocratic—or, as Lewis casts it, Satanic—drive to wipe out nature, and thereby control humanity), and, in particular, the corporate takeover of universities.
So I strongly recommend that book by C.S. Lewis; and if anyone can tell us, definitively, where that quote comes from, I would appreciate it greatly.
