The principal elements I have in mind are: (a) The strict division of the classes; i.e. the ruling class consisting of herdsmen and watch-dogs must be strictly separated from the human cattle. (b) The identification of the fate of the state with that of the ruling class; the exclusive interest in this class, and in its unity; and subservient to this unity, the rigid rules for breeding and educating this class, and the strict supervision and collectivization of the interests of its members.
