1. A system for propagating knowledge through perdurance, the system comprising: an event processor, which processes perdurance and epistemological relationships among entities; a search component, which locates entities having common perdurance or local epistemological properties; a perdurance engine, which traverses the perdurance relationships; an epistemological propagator, which generates derived epistemological relationships using the perdurance engine; and an intersection engine, which identifies the entities that have common derived epistemological properties.
