ABSTRACT
The general reason why sociocultural systems change in the course of their existence has been given by the principle of immanent change which was developed in the preceding chapter. The special reason why many sociocultural systems have recurrent nonidentical rhythms and turns, instead of proceeding forever in the same direction, or undergoing ever new changes devoid of any recurrence, or running in an identical cycle, is given by the principle of limits. It is implied in the principle of immanent change but has not been unfolded. Its unfolding is now in order.
