Feudalism, in the moral sense of the "five limbs," the children but also the parents are always dependent, the marriage of parental children have the right to arbitrary and "where to sit there." If the offspring are not satisfied with the wife (or husband) the parents specify, there is only a way out of the home. It is not necessary to know the love of children, only to find where the "subject to the parent" is the parents of the "matchmaking" to engage in engagement so bad marriage and marriage.
In ancient times the purpose of marriage is to maintain the family so marriage is the work of the clan, not the children's own. So the wife is married to the decision of the parents. The obligation of each person to ancestors, the family is to propagate later to "the eternal lineage", so the moral for the "unspoilt" is a great irrelevance. Marriage is not only a cause of blood, but also economic. The wife not only has to give birth to a daughter but also to work and care for housework for her husband's family.
