Famous quotes containing the word mass:

    In really hard times the rules of the game are altered. The inchoate mass begins to stir. It becomes potent, and when it strikes,... it strikes with incredible emphasis. Those are the rare occasions when a national will emerges from the scattered, specialized, or indifferent blocs of voters who ordinarily elect the politicians. Those are for good or evil the great occasions in a nation’s history.
    Walter Lippmann (1889–1974)

    It is strange to contemplate how little sympathy or encouragement the great mass of people have with one who differs from them in tastes, to the extent of desiring an education, while they are content with little or none.
    Caroline Nichols Churchill (1833–?)

    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)
