    “The central paradox of motherhood is that while our children become the absolute center of our lives, they must also push us back out in the world.... But motherhood that can narrow our lives can also broaden them. It can make us focus intensely on the moment and invest heavily in the future.”
    —Ellen Goodman (20th century)

    “We are now a nation of people in daily contact with strangers. Thanks to mass transportation, school administrators and teachers often live many miles from the neighborhood schoolhouse. They are no longer in daily informal contact with parents, ministers, and other institution leaders . . . [and are] no longer a natural extension of parental authority.”
    —James P. Comer (20th century)
