Cosmicism is the literary philosophy developed and used by the American writer H. P. Lovecraft in his weird fiction. Lovecraft was a writer of philosophically intense horror stories that involve occult phenomena like astral possession and alien miscegenation, and the themes of his fiction over time contributed to the development of this philosophy.
The philosophy of cosmicism states 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, and perhaps are just a small species projecting their own mental idolatries onto the vast cosmos. This also suggests that the majority of undiscerning humanity are creatures with the relative significance of insects and plants, when compared to the universe.
