The branch of philosophy asking "what exists?" What entities form this universe? Metaphysical studies can concern difficult, perhaps unanswerable, questions bordering theology. Ayer, (1971) used the term "transcendent metaphysics" for proposals of existence beyond the observable universe. Like Kant, he denied them a part in logic. As used here, metaphysics includes any suggestion that something, not immediately obvious, does exist.
freespace.virgin.net/john.hewitt1/pg_gloss.htm
That part of philosophical inquiry which attempts to answer such questions as "what is real?", "what really exists?" or "what are the ultimate, irreducible constitutents of reality?" Some typical metaphysical discussions center on such issues as whether or not the mind is distinct from something physical (for example, the brain), whether there are "universals"(qv) and if so what kind of being they have, whether there is or could be such a being as God.

A word that has come to mean the same thing as epistemology, distinguished mainly by way of its origin in the postumously given name to a work of Aristotle wherein he considers the science of "being as such" or question of cause (account of essential reality). That naming reflects the chronology of the work in relation to Aristotles' "Physics". The literal translation of metaphysics is "after physics". Metaphysics is also refered to as "First Philosophy".
