Metaphysics

Metaphysics is the branch of philosophy concerned with explaining the nature of the world. It is the study of being or reality. It addresses questions such as: What is the nature of reality? Is there a God? What is man's place in the universe?

A central branch of metaphysics is ontology, the investigation into what categories of things are in the world and what relations these things bear to one another. The metaphysician also attempts to clarify the notions by which people understand the world, including existence, objecthood, property, space, time, causality, and possibility.

More recently, the term "metaphysics" has also been used to refer to "subjects which are beyond the physical world". A "metaphysical bookstore," for instance, is not one that sells books on ontology, but rather one that sells books on spirits, faith healing, crystal power, occultism, and other such topics. This meaning is not recognized in academic philosophy.
