Famous quotes containing the words magic and/or number:

    Why not walk in the aura of magic that gives to the small things of life their uniqueness and importance? Why not befriend a toad today?
    Germaine Greer (b. 1939)

    The serial number of a human specimen is the face, that accidental and unrepeatable combination of features. It reflects neither character nor soul, nor what we call the self. The face is only the serial number of a specimen.
    Milan Kundera (b. 1929)
