Ontology - Objectivist vs Subjectivist

objectivist ontology (realism)

  • social and natural reality exist separately (i.e. independently)
  • the doctrine that universals or abstract concepts have an objective or absolute existence. The theory that universals have their own reality is sometimes called Platonic realism because it was first outlined by Plato’s doctrine of “forms” or ideas

subjectivist ontology (nominalism)

  • reality derived from cognitive processes
  • the doctrine that universals or general ideas are mere names without any corresponding reality, and that only particular objects exist; properties, numbers, and sets are thought of as merely features of the way of considering the things that exist. Important in medieval scholastic thought, nominalism is associated particularly with William of Occam
