Famous quotes containing the words structure and/or atomic:

    The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?”
    Jean Baker Miller (20th century)

    Take adultery or theft.
    Merely sins.
    It is evil who dines on the soul,
    stretching out its long bone tongue.
    It is evil who tweezers my heart,
    picking out its atomic worms.
    Anne Sexton (1928–1974)
