Famous quotes containing the word standards:

    The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    The technologist was the final guise of the white missionary, industrialization the last gospel of a dying race and living standards a substitute for a purpose in living.
    Max Frisch (1911–1991)

    To arrive at a just estimate of a renowned man’s character one must judge it by the standards of his time, not ours.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
