What is branch of knowledge?

Famous quotes containing the words knowledge and/or branch:

    The bases for historical knowledge are not empirical facts but written texts, even if these texts masquerade in the guise of wars or revolutions.
    Paul Deman (1919–1983)

    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)
