Metaphysics

Definition of Metaphysics

Met`a`phys´ics

n.	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. 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.	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.
