Famous quotes containing the words power and/or function:

    He
    moves in a wood of desire,

    pale antlers barely stirring
    as he hunts. I cannot tell
    what power is at work, drenched there
    with purpose, knowing nothing.
    Thom Gunn (b. 1929)

    No one, however powerful and successful, can function as an adult if his parents are not satisfied with him.
