I assume it to be generally admitted, that possibly man's first and probably his greatest advance toward order-and, therefore, toward civilization-was the creation of the family as the social nucleus. As Napoleon said, when the lawyers were drafting his Civil Code, "Make the family responsible to its head, and the head to me, and I will keep order in France." And yet although our dependence on the family system has been recognized in every age and in every land, there has been no restraint on personal liberty which has been more resented, by both men and women alike, than has been this bond which, when perfect, constrains one man and one woman to live a joint life until death shall them part, for the propagation, care, and defence of their children.
