What is branch of knowledge?

Famous quotes containing the words knowledge and/or branch:

    Each is liable to panic, which is exactly, the terror of ignorance surrendered to the imagination. Knowledge is the encourager, knowledge that takes fear out of the heart, knowledge and use, which is knowledge in practice. They can conquer who believe they can. It is he who has done the deed once who does not shrink from attempting again.
    Ralph Waldo Emerson (1803–1882)

    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)
