18 AFRICAN POLITICAL SYSTEMS sanction of force. The social system is, as it were, removed to a mystical plane, where it figures as a system of sacred values beyond criticism or revision. Hence people will overthrow a bad king, but the kingship is never questioned; hence the wars or feuds between segments of a society like the Nuer or the Tallensi are kept within bounds by mystical sanctions. These values are common to the whole society, to rulers and ruled alike and to all the segments and sections of a society. The African does not see beyond the symbols; it might well be held that if he understood their objective meaning, they would lose the power they have over him. This power lies in their symbolic content, and in their association with the nodal institutions of the social structure, such as the kingship. Not every kind of ritual or any sort of mystical ideas can express the values that hold a society together and focus the loyalty and devotion of its members on their rulers.

The mystical values reflect the general import of the basic elements of existence: the land as the source of the whole people's livelihood, physical health as something universally desired, the family as the fundamental pro-creative unit, and so forth. These are the common interests of the whole society, as the native sees them. These are the themes of taboos, observances and ceremonies in which, in societies of Group A, the whole people has a share through its representatives, and in societies of Group B all the segments participate, since they are matters of equal moment to all. We have stressed the fact that the universal aspect of things like land or fertility are the subjects of common interest in an African society; for these matters also have another side to them, as the private interests of individuals and segments of a society. The productivity of his own land, the welfare and security of his own family or his own clan, such matters are of daily, practical concern to every member of an African society; and over such matters arise the conflicts between sections and factions of the
