Famous quotes containing the words standard, assembly and/or language:

    “When Freedom, from her mountain height,
    Unfurled her standard to the air,
    She tore the azure robe of night,
    And set the stars of glory there;”
    —Joseph Rodman Drake (1795–1820)

    “That man is to be pitied who cannot enjoy social intercourse without eating and drinking. The lowest orders, it is true, cannot imagine a cheerful assembly without the attractions of the table, and this reflection alone should induce all who aim at intellectual culture to endeavor to avoid placing the choicest phases of social life on such a basis.”
    —Mrs. H. O. Ward (1824–1899)

    “Sarcasm I now see to be, in general, the language of the Devil; for which reason I have long since as good as renounced it.”
    —Thomas Carlyle (1795–1881)
