Metaphysics

Metaphysics is the branch of philosophy that examines the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among [the study of] the natural". It has been suggested that the term might have been coined by a first century AD editor who assembled various small selections of Aristotle’s works into the treatise we now know by the name Metaphysics (ta meta ta phusika, 'after the Physics ', another of Aristotle's works)
