    “Once we begin to appreciate that the apparent destructiveness of the toddler in taking apart a flower or knocking down sand castles is in fact a constructive effort to understand unity, we are able to revise our view of the situation, moving from reprimand and prohibition to the intelligent channeling of his efforts and the fostering of discovery.”
    —Polly Berrien Berends (20th century)

    “She’s just a child,
    but I’m the one who’s fainthearted.
    She’s the woman,
    but I’m the coward.
    She bears that high, swollen set of breasts,
    but I’m the one who’s burdened.
    The heavy hips are hers,
    but I’m unable to move.
    It’s a wonder
    how clumsy I’ve become
    because of flaws
    that shelter themselves
    in another.”
    —Amaru (c. seventh century A.D.)

    “Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.”
    —Ruth Hubbard (b. 1924)
