They Took Our Myths
In Lovecraft, nothing is pure evil, and nothing is good either. The moral of every Lovecraft story is: the world is more complicated than you think, and sometimes in ways that will shorten your lifespan! That’s a hard thing to swallow. Science fiction readers have a better time swallowing it, I think, than some other groups (novelty is part of the reason people choose science fiction over some other genres), but nobody particularly likes to think that everything they know is wrong. That said, it’s a realistic worldview – and Lovecraft was prescient in the sense that it’s a worldview that is far more clearly realistic now, when communications technologies have made it very easy to come across dissenting opinions and well-documented facts that explode your umwelt, than it was during an era when a telephone was an expensive luxury and basic literacy was far less common.
