Metaphysics

Metaphysics (Greek: τὰ μετὰ τὰ φυσικά) is one of the principal works of Aristotle & the first major work of the branch of philosophy with the same name. The principal subject is "being qua being", or being understood as being. It examines what can be asserted about anything that exists just because of its existence & not because of any special qualities it has. Also covered are different kinds of causation, form & matter, the existence of mathematical objects, & a prime-mover God.
