Famous quotes containing the words column and/or fourth:

    When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.
    Adrienne Rich (b. 1929)

    ... men and women are not yet free.... The slavery of greed endures. Little child workers, the hope of the future, are sacrificed to industry. Young men are sent out by the billion to die for profits.... We must destroy industrial slavery and build industrial democracy.... The people everywhere must come into possession of the earth [second, third, and fourth ellipses in source].
    Sara Bard Field (1882–1974)
