Famous quotes containing the words elevation and/or surface:
“In private life he was good-natured, chearful, social; inelegant in his manners, loose in his morals. He had a coarse, strong wit, which he was too free of for a man in his station, as it is always inconsistent with dignity. He was very able as a minister, but without a certain elevation of mind necessary for great good, or great mischief.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Bees
Shaking the heavy dews from bloom and frond.
Boys
Bursting the surface of the ebony pond.”
—Wilfred Owen (1893–1918)
