Metaphysics is a major branch of philosophy. It concerns existence and the nature of things that exist. Altogether it is a theory of reality.
Ontology is the part of metaphysics which discusses what exists: the categories of being. Apart from ontology, metaphysics concerns the nature of, and relations among, the things that exist.
Topics that are discussed in metaphysics include existence, objects and their traits, space and time, cause and effect, and what is possible.
