Famous quotes containing the word century:
“The innocence of those who grind the faces of the poor, but refrain from pinching the bottoms of their neighbour’s wives! The innocence of Ford, the innocence of Rockefeller! The nineteenth century was the Age of Innocence—that sort of innocence. With the result that we’re now almost ready to say that a man is seldom more innocently employed than when making love.”
—Aldous Huxley (1894–1963)
