Basic concepts of ontology.

Especially in relation to mereology:rV1

  • Ordinary objects: Average and obvious objects such as chairs.
  • Composition: All things are composed of simples.
  • Simples: Some basic component of the universe that is not composed itself. (In a “gunky” universe, though, there are no simples, just infinitely lower orders of composition. Contrast with “junky”, which has infinitely larger structures which everything rolls upward into.)
  • Existence has senses: The neutral sense refers literally to groups of simples, while the sortal sense refers to higher-level countable objects. Simples need an application condition to have enough information to distinguish things.
