Metaphysics can study which substances exist {ontology}|. Ontology is about being and existence. Being can have different modes. Beings can be abstract, concrete, universal, or particular. Beings can occupy space and time, be outside space and/or time, be independent of other being, be parts of other being, be parts of hierarchies, or be otherwise dependent.
