Author John Shirley has written an essay on why he likes “dark” literature – those genres that deal with the supernatural, horror, and so forth. The essay appears on Literati Literature Lovers. Here’s an excerpt:
It may be that the appeal of dark beauty is that it bridges these fearful gaps in existence: it brings symmetry to the asymmetrical; it brings liveliness to the symbols of death. In some paradoxical way it shows us how death isn’t the end. The scent of leaves decaying is not unpleasant—yet it’s a smell of decomposition. The glow from a jack-o-lantern is cheerful, though the carved face on the pumpkin may leer wickedly. A moonlit landscape seems to brood, to hint of dark secrets—yet it’s a glorious sight. What’s prettier, really, than an old graveyard with ornate headstones and mossy tombs? We weep at a funeral but we’re celebrating someone’s life.
