It is one of the things well known in the world that the husband's duties are in some way linked to those of the wife, and the wife's duties are associated with the husband's, these links and associations being effected and determined by their mutual help. But the primary duty, which binds, associates and brings together into one the souls and lives of the married couple is seeing jointly to the bringing up of children. In dealing with this the duties of husband and wife are at once different but linked. They are different in that seeing to the feeding of babies and the bringing up of children of either sex, and teaching girls up to the age at which they are given in marriage and transferred to the company of husbands, is the proper duty of the wife. But seeing to the education of boys between infancy and adolescence, and beyond this until they become independent, is the proper duty of the husband.

These duties are linked by the advice, support and many other forms of help rendered by one to the other. It is well known that both these sets of duties, both those which are linked and those which are different, both those which are shared and those which are special, bind the dispositions of a couple into one, the result of the action of what is called parental love. It is also well known that these duties as regards their difference and their linking make a single household.
