Famous quotes containing the word small:
“A certain degree of ceremony is a necessary outwork of manners, as well as of religion; it keeps the forward and petulant at a proper distance, and is a very small restraint to the sensible and to the well-bred part of the world.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
