    “Shea—they call him Scholar Jack—
    Went down the list of the dead.
    Officers, seamen, gunners, marines,
    The crews of the gig and yawl,
    The bearded man and the lad in his teens,
    Carpenters, coal-passers—all.”
    —Joseph I. C. Clarke (1846–1925)

    “Weigh what loss your honor may sustain
    If with too credent ear you list his songs,
    Or lose your heart, or your chaste treasure open
    To his unmastered importunity.”
    —William Shakespeare (1564–1616)

    “In every philosophical school, three thinkers succeed one another in the following way: the first produces out of himself the sap and seed, the second draws it out into threads and spins a synthetic web, and the third waits in this web for the sacrificial victims that are caught in it—and tries to live off philosophy.”
    —Friedrich Nietzsche (1844–1900)

    “Barbarisation may be defined as a cultural process whereby an attained condition of high value is gradually overrun and superseded by elements of lower quality.”
