A branch of philosophy that studies the fundamental nature of reality, including concepts such as being, existence, and the universe.
The philosopher wrote extensively on the metaphysic of existence and reality.
Metaphysic → It is formed from "meta-" (meaning beyond or after) and "physika" (from Greek "phusis", meaning nature). The term refers to the study of that which is beyond the physical or natural world.
Think of 'beyond' ('meta-') the 'natural' ('physika') to remember that metaphysic deals with concepts that transcend the physical world.
