In a modern family the parents exercise a certain degree of control over the children, but this is limited in several respects. No parent is allowed to put a child to death, or to permit him to grow up in ignorance. On the other hand, the parent is not allowed to protect the child from arrest if a serious injury has been done by him. The _State_, through its laws and officers, is regarded by us as the highest authority in a certain great sphere of action. It must settle conflicting claims and protect life and property; in the opinion of many it must organize the life of its members where the coöperation of every member is necessary for some common good. In early group life there may or may not be some political body over and above the clan or family, but in any case the _kin or family is itself a sort of political State_. Not a State in the sense that the political powers are deliberately separated from personal, religious, and family ties; men gained a new conception of authority and rose to a higher level of possibilities when they consciously separated and defined government and laws from the undifferentiated whole of a religious and kindred group. But yet this primitive group was after all a State, not a mob, or a voluntary society, or a mere family; for (1) it was a more or less permanently organized body; (2) it exercised control over its members which they regarded as rightful authority, not as mere force; (3) it was not limited by any higher authority, and acted more or less effectively for the interest of the whole. The representatives of this political aspect of the group may be chiefs or sachems, a council of elders, or, as in Rome, the House Father, whose _patria potestas_ marks the extreme development of the patriarchal family. The control exercised by the group over individual members assumes various forms among the different peoples. The more important aspects are a right over life and bodily freedom, in some cases extending to power of putting to death, maiming, chastising, deciding whether newly born children shall be preserved or not; the right of betrothal, which includes control over the marriage portion received for its women; and the right to administer property of the kin in behalf of the kin as a whole. It is probable that among all these various forms of control, the control over the marriage relations of women has been most persistent. One reason for this control may have been the fact that the group was bound to resent injuries of a member of the group who had been married to another. Hence this responsibility seemed naturally to involve the right of decision as to her marriage.
