What is the case, the fact, is the existence of atomic facts.
2.01 (4) An atomic fact is a combination of objects (entities, things).
2.03 (4) In the atomic fact objects hang one in another, like the links of a chain.
2.04 The totality of existent atomic facts is the world.
2.05 The totality of existent atomic facts also determines which atomic facts do not exist.
2.06 (3) The existence and non-existence of atomic facts is the reality.
(The existence of atomic facts we also call a positive fact, their non-existence a negative fact.)
