Learning
Learning is like a lark, that can mount, and sing, and please herself, and nothing else; but may know that she holdeth as well as the hawk, that can soar aloft, and can also descend and strike upon the prey.
—Francis Bacon
Wear your learning like your watch, in a private pocket, and do not pull it out and strike it merely to show that you have one.
—Earl of Chesterfield
Learning is like mercury, one of the most powerful and excellent things in the world in skillful hands; in unskillful, the most mischievous.
—Alexander Pope
Learning, like money, may be of so base a coin as to be utterly void of use.
—William Shenstone
Learning, like the lunar beam, affords light.
—Edward Young
