métaphysique. See Physics. The term was first used by the followers of

Aristotle as a name for that part of his writings which came after, or

followed, the part which treated of physics.] 1. The science of real as

distinguished from phenomenal being; ontology; also, the science of

being, with reference to its abstract and universal conditions, as

distinguished from the science of determined or concrete being; the

science of the conceptions and relations which are necessarily implied

as true of every kind of being; philosophy in general; first

principles, or the science of first principles.

Metaphysics is distinguished as general and special. General

metaphysics is the science of all being as being. Special metaphysics

is the science of one kind of being; as, the metaphysics of chemistry,

of morals, or of politics. According to Kant, a systematic exposition

of those notions and truths, the knowledge of which is altogether

independent of experience, would constitute the science of metaphysics.

Commonly, in the schools, called metaphysics, as being part of the

philosophy of Aristotle, which hath that for title; but it is in

another sense: for there it signifieth as much as "books written or

placed after his natural philosophy." But the schools take them for

"books of supernatural philosophy;" for the word metaphysic will

bear both these senses.

Hobbes.

Now the science conversant about all such inferences of unknown

being from its known manifestations, is called ontology, or

metaphysics proper.

Sir W. Hamilton.

Metaphysics are [is] the science which determines what can and what

can not be known of being, and the laws of being, a priori.

Coleridge.

2. Hence: The scientific knowledge of mental phenomena; mental

philosophy; psychology.

Metaphysics, in whatever latitude the term be taken, is a science

or complement of sciences exclusively occupied with mind.

Sir W. Hamilton.

Whether, after all, A larger metaphysics might not help Our

physics.

Mrs. Browning.
