Famous quotes containing the word families:
“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)
“We are born into them, marry into them, even create them among the people we love. They come large and extended...or small and nuclear. But whatever their size or wherever they live, strong families give us the nurturance and strength we need in order to survive.”
—Andrea Davis (20th century)
“The brotherhood of men does not imply their equality. Families have their fools and their men of genius, their black sheep and their saints, their worldly successes and their worldly failures. A man should treat his brothers lovingly and with justice, according to the deserts of each. But the deserts of every brother are not the same.”
—Aldous Huxley (1894–1963)
