The Immanentist Underground.

The one-sentence version

The immanentist underground is the tradition of thought that refuses to split nature from value, becoming from structure, or potentiality from actuality. It spans Spinoza through contemporary process ontology.

Where the term comes from

The “underground” names the fact that this tradition was often marginalized or read against its own intentions. Spinoza was banned, Bergson was systematically misread as vitalist, Whitehead remained academic, Simondon was recently discovered, and DeLanda rehabilitated them all.

Why it matters

Ontogony stands on the shoulders of the immanentist underground. Without this genealogy, the claim that being itself is generative, layered, and value-laden would have no philosophical grounding.
