Famous quotes containing the words families, common and/or origin:

    Women have entered the work force . . . partly to express their feelings of self-worth . . . partly because today many families would not survive without two incomes, partly because they are not at all sure their marriages will last. The day of the husband as permanent meal-ticket is over, a fact most women recognize, however they feel about “women’s liberation.”
    Robert Neelly Bellah (20th century)

    How like a prodigal doth nature seem,
    When thou, for all thy gold, so common art!
    Thou teachest me to deem
    More sacredly of every human heart,
    Since each reflects in joy its scanty gleam
    Of Heaven, and could some wondrous secret show,
    Did we but pay the love we owe,
    And with a child’s undoubting wisdom look
    On all these living pages of God’s book.
    James Russell Lowell (1819–1891)

    Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.
    Oscar Wilde (1854–1900)
