That which is gained and preserved by knowing; instruction; acquaintance; enlightenment; learning; scholarship; erudition. The psychological result of perception and learning and reasoning. See in college how we thwart the natural love of learning by leaving the natural method of teaching what each wishes to learn, and insisting that you shall learn what you have no taste or capacity for. Learned men are the cisterns of knowledge, not the fountainheads. Their irritating unwillingness to learn how to do things my way has usually led to my doing things their way; most of the time, they have been right.

More about knowledge. More about intelligence.
