Cosmicism

Cosmicism is a name given to the literary philosophy that H. P. Lovecraft developed and used for his fiction. The name is commonly stated to have been coined by Lovecraft himself, though no sources that state this claim provide any statements by Lovecraft himself using it. Lovecraft was a writer of horror stories that involve occult phenomena like astral projection and alien miscegenation, and the themes of his fiction over time contributed to the development of this philosophy.

The philosophy of cosmicism is explained as the idea that "there is no recognizable divine presence, such as a god, in the universe, and that humans are particularly insignificant in the larger scheme of intergalactic existence." The most prominent theme is humanity's fear of their insignificance in an incomprehensibly large universe: a fear of the cosmic void.
