Famous quotes containing the words reference and/or clock:

    “If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
    —William York Tindall (1903–1981)

    “What says the Clock in the Great Clock Tower?
    And all alone comes riding there
    The King that could make his people stare,
    Because he had feathers instead of hair.
    A slow low note and an iron bell.”
    —William Butler Yeats (1865–1939)
