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 brought them there so far from their home,
    Cuchulain that fought night long with the foam,
    What says the Clock in the Great Clock Tower?
    Niamh that rode on it; lad and lass
    That sat so still and played at the chess?
    What but heroic wantonness?
    William Butler Yeats (1865–1939)
