Famous quotes containing the word mass:

    It is a mass language only in the same sense that its baseball slang is born of baseball players. That is, it is a language which is being molded by writers to do delicate things and yet be within the grasp of superficially educated people. It is not a natural growth, much as its proletarian writers would like to think so. But compared with it at its best, English has reached the Alexandrian stage of formalism and decay.
    Raymond Chandler (1888–1959)

    The best reason why Monarchy is a strong government is, that it is an intelligible government. The mass of mankind understand it, and they hardly anywhere in the world understand any other.
    Walter Bagehot (1826–1877)

    When over Catholics the ocean rolls,
    They must wait several weeks before a mass
    Takes off one peck of purgatorial coals,
    Because, till people know what’s come to pass,
    They won’t lay out their money on the dead—
    It costs three francs for every mass that’s said.
    George Gordon Noel Byron (1788–1824)
