Speculative ontology aims to determine which entities actually exist, for example, whether there are numbers or whether time is an illusion. [81] Martin Heidegger proposed fundamental ontology to study the meaning of being. Metaontology studies the underlying concepts, assumptions, and methods of ontology.
More simply, an ontology is a way of showing the properties of a subject area and how they are related, by defining a set of terms and relational expressions that represent the entities in that subject area. The field which studies ontologies so conceived is sometimes referred to as applied ontology. [1]

In ontology, the theory of categories concerns itself with the categories of being: the highest genera or kinds of entities. [1] To investigate the categories of being, or simply categories, is to determine the most fundamental and the broadest classes of entities. [2]
An ontology that includes representations of those semantic primitives could in such a case be used to create logical descriptions of any term that a person may wish to define logically. That ontology would be one form of upper ontology, serving as a logical "interlingua" that can translate ideas in one terminology to its logical equivalent in ...

However, if ontology refers to the study of reality then ontological anthropology incorporates theoretical and methodological elements of anthropology to a study of being or existence. [3]

If one affirms a statement using a name or other singular term, or an initial phrase of 'existential quantification', like 'There are some so-and-sos', then one must either (1) admit that one is committed to the existence of things answering to the singular term or satisfying the descriptions ...
