Famous quotes containing the word objects:

    “It is a misfortune that necessity has induced men to accord greater license to this formidable engine, in order to obtain liberty, than can be borne with less important objects in view; for the press, like fire, is an excellent servant, but a terrible master.”
    —James Fenimore Cooper (1789–1851)
