Knowledge, n.
Etymology: [OE. knowlage, knowlege, knowleche, knawleche. The last part is the Icel. suffix -leikr, forming abstract nouns, orig. the same as Icel. leikr game, play, sport, akin to AS. lac, Goth. laiks dance. See Know, and cf. Lake, v. i., Lark a frolic.]
1. The act or state of knowing; clear perception of fact, truth, or duty; certain apprehension; familiar cognizance; cognition. Knowledge, which is the highest degree of the speculative faculties, consists in the perception of the truth of affirmative or negative propositions. Locke.
2. That which is or may be known; the object of an act of knowing; a cognition; -- chiefly used in the plural. There is a great difference in the delivery of the mathematics, which are the most abstracted of knowledges. Bacon. Knowledges is a term in frequent use by Bacon, and, though now obsolete, should be revived, as without it we are compelled to borrow "cognitions" to express its import. Sir W. Hamilton. To use a word of Bacon's, now unfortunately obsolete, we must determine the relative value of knowledges. H. Spencer.
3. That which is gained and preserved by knowing; instruction; acquaintance; enlightenment; learning; scholarship; erudition. Knowledge puffeth up, but charity edifieth. 1 Cor. viii. 1. Ignorance is the curse of God; -Knowledge, the wing wherewith we fly to heaven. Shak.

Shades of meaning
Knowledge is all that the mind knows, from whatever source derived or obtained, or by whatever process; the aggregate of facts, truths, or principles acquired or retained by the mind, including alike the intuitions native to the mind and all that has been learned respecting phenomena, causes, laws, principles, literature, etc. There is a tendency to regard knowledge as accurate and systematic, and to a certain degree complete. Information is knowledge of fact, real or supposed, derived from persons, books, or observation, and is regarded as casual and haphazard. We say of a studious man that he has a great store of knowledge, or of an intelligent man of the world, that he has a fund of varied information. Lore is used only in poetic or elevated style, for accumulated knowledge, as of a people or age, or in a more limited sense for learning or erudition. We speak of perception of external objects, apprehension of intellectual truth. Simple perception gives a limited knowledge of external objects, merely as such; the cognition of the same objects is a knowledge of them in some relation; cognizance is the formal or official recognition of something as an object of knowledge; we take cognizance of it. Intuition is primary knowledge antecedent to all teaching or reasoning, experience is knowledge that has entered directly into one's own life; as, a child's experience that fire will burn. Learning is much higher than information, being preeminently wide and systematic knowledge, the result of long, assiduous study; erudition is recondite learning secured only by extraordinary industry, opportunity, and ability. Compare acquaintance; education; science; wisdom.
