In this new “primitive feudal state of higher grade,” as we shall call it, the ruling group may, therefore, disintegrate into a number of more or less powerful and privileged strata. The organization may show many varieties because of the well-known fact, that often the master group separates into two subordinated economic and social layers, developed as we saw them in the herdsmen stage: the owners of large herds and of many slaves, and the ordinary freemen. Possibly the less complete differentiation into social ranks in the states created by huntsmen in the new world, is to be assigned to the circumstance that in the absence of herds, the concomitants of that form of ownership, and the original separation into classes, were not introduced into the state. We shall, later, see what force was exerted on the political and economic development of states in the old world by the differences in rank and property of the two strata of rulers.
Similarly, as in the case of the ruling group, a corresponding process of differentiation divides the subject group in the “primitive feudal state of a higher grade” into various strata more or less despised and compelled to render service. It is only necessary to recall the very marked difference in the social and jural position occupied by the peasantry in the Doric States, Lacedæmon and Crete, and among the Thessalians, where the perioiki had clear rights of possession and fairly well protected political rights, while the helots, in the latter case the _penestai_, were almost unprotected in life and property. Among the old Saxons also we find a class, the liti, intermediate between the common freemen and the serfs.[52] These examples could be multiplied; apparently they are caused by the same tendencies that brought about the differentiation among the nobility mentioned above. When two primitive feudal states amalgamate, their social layers stratify in a variety of ways, which to a certain extent are comparable to the combinations resulting from mixing together two packs of cards.
It is certain that this mechanical mixture caused by political forces, influences the development of _castes_, that is to say, of hereditary professions, which at the same time form a hierarchy of social classes. “Castes are usually, if not always, consequences of conquest and subjugation by foreigners.”[53] Although this problem has not been completely solved, it may be said that the formation of castes has been very strongly influenced by economic and religious factors. It is probable that castes came about in some such way as this: state-forming forces penetrated into existing economic organizations, and vocations underwent adaptation, and then became petrified under the influence of religious concepts, which, however, may also have influenced their original formation. This seems to follow from the fact that even as between man and woman there exist certain separations of vocation, which, so to say, are taboo and impassable. Thus among all huntsmen, tilling the ground is woman’s work, while among many African shepherds, as soon as the ox-plow is used, agriculture becomes man’s work, and then women may not, under pain of sacrilege, use the domestic cattle.[H]
