Famous quotes containing the words reversed and/or inequality:

    His reversed body gracefully curved, his brown legs hoisted like a Tarentine sail, his joined ankles tacking, Van gripped with splayed hands the brow of gravity, and moved to and fro, veering and sidestepping, opening his mouth the wrong way, and blinking in the odd bilboquet fashion peculiar to eyelids in his abnormal position. Even more extraordinary than the variety and velocity of the movements he made in imitation of animal hind legs was the effortlessness of his stance.
    Vladimir Nabokov (1899–1977)

    The doctrine of equality!... But there exists no more poisonous poison: for it seems to be preached by justice itself, while it is the end of justice.... “Equality for equals, inequality for unequals”Mthat would be the true voice of justice: and, what follows from it, “Never make equal what is unequal.”
    Friedrich Nietzsche (1844–1900)
