Famous quotes containing the words double and/or action:

    “American families, however, without exception, experience a double message in our society, one that claims a commitment to families and stresses the importance of raising bright, stable, productive citizens, yet remains so bound by an ideal of “rugged individualism” that parents receive little support in their task from the public or private sectors.”
    —Bernice Weissbourd (20th century)

    “Let those who go home tell the same story of you:
    Of action with a common purpose, action
    None the less fruitful if neither you nor we
    Know, until the moment after death
    What is the fruit of action.”
    —T.S. (Thomas Stearns)
