Prime Abstractions Ontology

Every prime listed below links to its full entry. This is the canonical category-and-sub-category tree; use it as a structured browse view of the corpus.

An asterisk (*) following a slug marks an emergent prime abstraction — a candidate that may be re-classified as a prime abstraction once further evidence and practice demonstrates its utility.
