Famous quotes containing the words surrogate and/or key:

    “Detachment is the prerogative of an elite; and as the dandy is the nineteenth century’s surrogate for the aristocrat in matters of culture, so Camp is the modern dandyism. Camp is the answer to the problem: how to be a dandy in the age of mass culture.”
    —Susan Sontag (b. 1933)

    “The knight slew the dragon,
    The lady was gay,
    They rode on together,
    Away, away.”
    —Unknown. This Is the Key (l. 38–41)
