Among the Siouan Indians the devices of taboo, kin-names, and ordination are found in such relation as to throw some light on the growth of primitive institutions. While they blend and are measurably involved with thaumaturgic devices, there are indications that in a general way the three devices stand for stages in the development of law. Among the best-known tribes the taboo pertained to the clan, and was used (in a much more limited way than among some other peoples) to commemorate and perpetuate the clan organization; kin-names, which were partly natural and thus normal to the clan organization, and at the same time partly artificial and thus characteristic of gentile organization, served to commemorate and perpetuate not only the family relations but the relations of the constituent elements of the tribe; while the ordination, expressed in the camping circle, in the phratries, in the ceremonials, and in many other ways, served to commemorate intertribal as well as intergentile relations, and thus to promote peace and harmonious action. It is significant that the taboo was less potent among the Siouan Indians than among some other stocks, and that among some tribes it has not been found; and it is especially significant that in some instances the taboo was apparently inversely related to kin-naming and ordination, as among the Biloxi, where the taboo is exceptionally weak and kin-naming exceptionally strong, and among the Dakota, where the system of ordination attained perhaps its highest American development in domiciliary arrangement, while the taboo was limited in function; for the relations indicate that the taboo was archaic or even vestigial. It is noteworthy also that among most of the Siouan tribes the kin-name system was less elaborate than in many other stocks, while the system of ordination is so elaborate as to constitute one of the leading characteristics of the stock.
At the time of the discovery, most of the Siouan tribes had apparently passed into gentile organization, though vestiges of clan organization were found—e.g., among the best-known tribes the man was the head of the family, though the tipi usually belonged to the woman. Thus, as defined by institutions, the stock was just above savagery and just within the lower stages of barbarism. Accordingly the governmental functions were hereditary in the male line, yet the law of heredity was subject to modification or suspension at the will of the group, commonly at the instance of rebels or usurpers of marked prowess or shrewdness. The property regulations were definite and strictly observed; as among other barbarous peoples, the land was common to the tribe or other group occupying it, yet was defended against alien invasion; the ownership of movable property was a combination of communalism and individualism delicately adjusted to the needs and habits of the several tribes— in general, evanescent property, such as food and fuel, was shared in common (subject to carefully regulated individual claims), while permanent property, such as tipis, dogs, apparel, weapons, etc, was held by individuals. As among other tribes, the more strictly personal property was usually destroyed on the death of the owner, though the real reason for the custom—the prevention of dispute—was shrouded in a mantle of mysticism.
Although of primary importance in shaping the career of the Siouan tribes, the marital institutions of the stock were not specially distinctive. Marriage was usually effected by negotiation through parents or elders; among some of the tribes the bride was purchased, while among others there was an interchange of presents. Polygyny was common; in several of the tribes the bride's sisters became subordinate wives of the husband. The regulations concerning divorce and the punishment of infidelity were somewhat variable among the different tribes, some of whom furnished temporary wives to distinguished visitors. Generally there were sanctions for marriage by elopement or individual choice. In every tribe, so far as known, gentile exogamy prevailed—i.e., marriage in the gens was forbidden, under pain of ostracism or still heavier penalty, while the gentes intermarried among one another; in some cases intermarriage between certain tribes was regarded with special favor. There seems to have been no system of marriage by capture, though captive women were usually espoused by the successful tribesmen, and girls were sometimes abducted. In general it would appear that intergentile and intertribal marriage was practiced and sanctioned by the sages, and that it tended toward harmony and federation, and thus contributed much toward the increase and diffusion of the great Siouan stock.
As set forth in some detail by Dorsey, the ordination of the Siouan tribes extended beyond the hierarchic organization into families, subgentes, gentes, tribes, and confederacies; there were also phratries, sometimes (perhaps typically) arranged in pairs; there were societies or associations established on social or fiducial bases; there was a general arrangement or classification of each group on a military basis, as into soldiers and two or more classes of noncombatants, etc. Among the Siouan peoples, too, the individual brotherhood of the David-Jonathan or Damon-Pythias type was characteristically developed. Thus the corporate institutions were interwoven and superimposed in a manner nearly as complex as that found in the national, state, municipal, and minor institutions of civilization; yet the ordination preserved by means of the camping circle, the kinship system, the simple series of taboos, and the elaborate symbolism was apparently so complete as to meet every social and governmental demand.
Beliefs
The Development Of Mythology
As explained by Powell, philosophies and beliefs may be seriated in four stages: The first stage is hecastotheism; in this stage extranatural or mysterious potencies are imputed to objects both animate and inanimate. The second stage is zootheism; within it the powers of animate forms are exaggerated and amplified into the realm of the supernal, and certain animals are deified. The third stage is that of physitheism, in which the agencies of nature are personified and exalted unto omnipotence. The fourth stage is that of psychotheism, which includes the domain of spiritual concept. In general the development of belief coincides with the growth of abstraction; yet it is to be remembered that this growth represents increase in definiteness of the abstract concepts rather than augmentation in numbers and kinds of subjective impressions, i.e., the advance is in quality rather than in quantity; indeed, it would almost appear that the vague and indefinite abstraction of hecastotheism is more pervasive and prevalent than the clearer abstraction of higher stages. Appreciation of the fundamental characteristics of belief is essential to even the most general understanding of the Indian mythology and philosophy, and even after careful study it is difficult for thinkers trained in the higher methods of thought to understand the crude and confused ideation of the primitive thinker.
In hecastotheism the believer finds mysterious properties and potencies everywhere. To his mind every object is endued with occult power, moved by a vague volition, actuated by shadowy motive ranging capriciously from malevolence to benevolence; in his lax estimation some objects are more potent or more mysterious than others, the
