Carter found it fascinating that Lovecraft, a thorough materialist, could enthrall the world with his terrifying tales of “evil and fallen gods.” Carter’s take was that Lovecraft utilized his firm grasp of science and materialist outlook to craft stories made believable with concrete details and methodical precision.
Ira Levin, the author of Rosemary’s Baby and Veronica’s Room, used an approach similar to Lovecraft’s. Like HPL, Levin was an atheist, yet his horror tales make supernatural evil seem frighteningly real, even palpable. In both the novel and Roman Polanski’s excellent screen adaptation, Rosemary’s Baby draws you in with odd but apparently mundane details. The realtor who helps Rosemary and her husband Guy find an apartment is missing fingers. When Rosemary and Guy move a dresser from the wall, they realize it hides a secret room — but it’s only an empty closet.
Nothing to see there, right?
As the truth about these seemingly innocent details slowly comes out, you’re fascinated by the inescapable conclusion that there’s something sinister going on, and it’s impossible to turn away. Like Rosemary, you’re in this thing now and there’s no turning back.
So why are confirmed materialists such as Lovecraft and Levin drawn to supernatural subjects? And what enables them to be so convincing?
Both men knew that writing depends on exaggeration and metaphor. I like the way Flannery O’Connor put it: “When you can assume that your audience holds the same beliefs you do, you can relax a little and use more normal ways of talking to it; when you have to assume that it does not, then you have to make your vision apparent by shock — to the hard of hearing you shout, and for the almost blind you draw large and startling figures.”
Of course, O’Connor was a traditional Catholic who aimed to make readers perceive supernatural evil by vividly presenting earthly evil.
