The notion of of all significance being contained somehow entirely in the self-perception of one apparently separate individual - now that is horrifying. Whereas I think our relative in(significance/consequence) is quite comforting, comparitavly, benign, to rip-off the French.
Isn't that sort of the premise of Hitchhiker's Guide to the Galaxy, though? That the boring shithole existence on earth is representative of the whole universe?
Iain Banks had a character in one of his books pitch a movie idea - aliens as tourists (the 'elite', which brings to mind retired rockstars and dotcom billionaires), coming to see the eclipse (because - according to the character - our planet is one of the only ones with a perfect lunar eclipse).
I think that could be an interesting setup. The story of a shallow alien who comes for the thrills, and the slow, horrible realization that this kind of utterly mundane and familiar motivation is in fact all there is out there.
Kind of an anti-Lovecraft. We have seen the alien, and understood it completely.
This is even scarier than terrors unutterable and Actually Kind of Droll.
Sort of, but I'm not sure I would classify HHGTTG as "opposite of Lovecraft", if anything it's a bit like Lovecraft's nihilism and cynicism taken further to the point where they are no longer recognizable. Even the profound is meaningless and mediocre, such deities as there are are inept, the universe is doomed (and you can go and gawk at said doom of you have the money), and mindshattering lovecraftian theophanies of cosmic horror can be induced at will using a piece of fairy cake and some fancy electronics. Human life does have a purpose, but it's a trite purpose derived from part of a cynical scheme to profitize philosophy and it effectively does nothing to prevent humanity from being destroyed.
The Total Perspective Vortex is particularly noteworthy because its essentially based on exactly the philosophical point that much of lovecraft's fiction was allegedly trying to make, that no matter who you are you're utterly insignificant and inconsequential compared to the vastness of the universe, and that only our inability to comprehend and mentally internalize this vastness allows us to have any sort of drive, self regard, or hope or satisfaction; that if we could truly comprehend our own insignificance - and the insignificance and impermanance of eberything that we value - we would be struck down simply by the sheer awfulness of the revelation
Both Lovecraft and Adams had their own ideas about what constituted a horrifying form of normalcy to apply to alien creatures. Lovecraft's was mechanistic and neodarwinian -- ancient and immensely powerful alien races are just hungry unthinking predators; Adams's horror is not that aliens are wild animals, but that aliens are american.
I think I would enjoy them both. The latter I am not so familiar with although I think I kind of understand, like Meursault standing before the yawning abyss of an itinerant American on permanent vacation. Which still is not that bad, inherently at least. Great comparison nonetheless.
