Famous quotes containing the words execution of, execution and/or commands:

    The application requisite to the duties of the office I hold [governor of Virginia] is so excessive, and the execution of them after all so imperfect, that I have determined to retire from it at the close of the present campaign.
    Thomas Jefferson (1743–1826)

    If Germany is to become a colonising power, all I say is, “God speed her!” She becomes our ally and partner in the execution of the great purposes of Providence for the advantage of mankind.
    —W.E. (William Ewart)

    The power of a text is different when it is read from when it is copied out.... Only the copied text thus commands the soul of him who is occupied with it, whereas the mere reader never discovers the new aspects of his inner self that are opened by the text, that road cut through the interior jungle forever closing behind it: because the reader follows the movement of his mind in the free flight of day-dreaming, whereas the copier submits it to command.
    Walter Benjamin (1892–1940)
