Famous quotes containing the word circuit:

    We are all hostages, and we are all terrorists. This circuit has replaced that other one of masters and slaves, the dominating and the dominated, the exploiters and the exploited.... It is worse than the one it replaces, but at least it liberates us from liberal nostalgia and the ruses of history.
    Jean Baudrillard (b. 1929)

    each new victim treads unfalteringly
    The never altered circuit of his fate,
    Bringing twelve peers as witness
    Both to his starry rise and starry fall.
    Robert Graves (1895–1985)

    The Father and His angelic hierarchy
    That made the magnitude and glory there
    Stood in the circuit of a needle’s eye.
    William Butler Yeats (1865–1939)
