\Phi*los"o*phy\, n.; pl. {Philosophies}. [OE. philosophie, F. philosophie, L. philosophia, from Gr. ?. See {Philosopher}.] 1. Literally, the love of, including the search after, wisdom; in actual usage, the knowledge of phenomena as explained by, and resolved into, causes and reasons, powers and laws. Note: When applied to any particular department of knowledge, philosophy denotes the general laws or principles under which all the subordinate phenomena or facts relating to that subject are comprehended. Thus philosophy, when applied to God and the divine government, is called theology; when applied to material objects, it is called physics; when it treats of man, it is called anthropology and psychology, with which are connected logic and ethics; when it treats of the necessary conceptions and relations by which philosophy is possible, it is called metaphysics. Note: ``Philosophy has been defined: tionscience of things divine and human, and the causes in which they are contained; -- the science of effects by their causes; -- the science of sufficient reasons; -- the science of things possible, inasmuch as they are possible; -- the science of things evidently deduced from first principles; -- the science of truths sensible and abstract; -- the application of reason to its legitimate objects; -- the science of the relations of all knowledge to the necessary ends of human reason; -- the science of the original form of the ego, or mental self; -- the science of science; -- the science of the absolute; -- the scienceof the absolute indifference of the ideal and real.'' --Sir W. Hamilton. 2. A particular philosophical system or theory; the hypothesis by which particular phenomena are explained. [Books] of Aristotle and his philosophie. --Chaucer.
