One of the many things that makes Lovecraft interesting, at least for me, is the discussion of why his writing work, if it does work for you (and despite my jokes about gambrel rooftops and fishmen, it does work for me most of the time). Everyone has their own reasons. Some can be agreed upon by the larger body of Lovecraft fans. Others are acutely personal. My example has always been my tendency to go backpacking in the wilds of New England, seeing firsthand how, even in our modern, developed world, civilization can vanish abruptly, leaving you surrounded by nothing but the night and woods. Even in those small states, the amount of land that gives way to untamed solitude is vast, and when you walk into the middle of it with nothing but boil-in-bag stroganoff and a headlamp to fend off the grip of the wilderness, it becomes a lot easier to believe Lovecraft’s tales of ancient things lurking in the mountains and foothills. You look up and realize how tiny you are. You look around an realize how vulnerable you are. Wolves, bears, and rutting moose are bad enough. I guess if I had to also deal with chattering crab monsters from space, I’d find them a lot scarier than I might have while sitting at home with a dram of Glenmorangie, reading The Whisperer in the Darkness. Because as has been pointed out to me in discussion, it’s not so much the monster as it is the isolation.
