Famous quotes containing the word activity:

    “Genghis Khan, in his usual jodhpurs accessorized with whip, straddled a canvas chair and gloated upon the fairyland he had built. Journalists, photographers, secretaries, sycophants, script girls, and set dressers milled and stirred around him, activity ... irresistibly reminiscent of the movement of maggots upon rotting meat.”
    —Angela Carter (1940–1992)

    “Humour is by far the most significant activity of the human brain.”
    —Edward De Bono (b. 1933)

    “In communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.”
    —Karl Marx (1818–1883)
