Famous quotes containing the words magic and/or number:

    Thou treacherous, base deserter of my flame,
    False to my passion, fatal to my fame,
    Through what mistaken magic dost thou prove
    So true to lewdness, so untrue to love?
    John Wilmot, Earl Of Rochester (1647–1680)

    If matrimony be really beneficial to society, the custom that ... married women alone are allowed any claim to place, is as useful a piece of policy as ever was invented.... The ridicule fixed on the appellation of old maid hath, I doubt not, frightened a very large number into the bonds of wedlock.
    Sarah Fielding (1710–1768)
