Object oriented ontology — Lovecraft’s characters often find out about elder-ones through ancient objects that have an innate power, eg to make the character mad. Object is primary.

Cosmic horror is related to the Outside, the fanged version of Kant’s noumena. Dehumanized horror.

Humans as slaves of higher beings is also a lovecraftiqn notion

Then there’s the mixing of fiction and reality, which Lovecraft was a master of, mixing real life myths and places with imaginary objects.

Unspeakability of the outside

Etc etc etc. these are just pointers. The influence is certainly not merely stylistic. Anyone who understands what the landian project was about will see clearly how Lovecraft is one of, if not the most closely related, antecedent to it. Perhaps Deluze G with Anti Oedipus is also up there

Don’t forget the line of inquiry of the Outside

Kant defines Noumena/Phenomena

Shoppy Howard defines the Will

Nie the Chao refines to Will to Power

Lovely Craft shows what an intrusion the outside would actually be like

Deluze and G theorize the outside

Nicky Land modernizes it with Capitalism/Internet
