+528+. The fact that some of the least-advanced American tribes, particularly the Eskimo and the California tribes, show no signs of totemistic organization[879] makes against the view that totemism was the initial form of human society, but its historical background is not known. In any case it does not invalidate what is said above of the rôle of agriculture in the modification of savage institutions. The lines of savage growth have been various--a general law of development cannot be laid down; the history of every community must be studied for itself, and its testimony must be given its appropriate value. In this way it will be possible to give a sketch of totemistic forms and suggestions, if not a history of totemism. +529+. _Individualistic institutions._ The development of individualism, a universal accompaniment of general social progress, is unfavorable to totemism, since in this latter the individual is subordinated to the clan. To assert one's self as an individual is practically to ignore the totem, whose function pertains to the clan as a whole, without separate recognition of its members. Revolt against the supremacy of the clan (if that expression is allowable) has shown itself from an early social stage and in all parts of the world. The principal forms in which it appears are the institution of voluntary societies, and the adoption of personal guardians by individuals. +530+. _Secret societies._ It is a common custom in the lower tribes to keep the sexes separate and to distinguish between the initiated and the uninitiated. There are often men's houses in which the young unmarried males are required to live.[880] Women and boys are forbidden to be present at ceremonies of initiation when, as in some instances, the secrets of the tribe are involved. Thus there arise frequently secret associations of males, who conduct tribal affairs. But these associations are not voluntary--all initiated men belong to them perforce--and they are not divorced from totemic relations. The real voluntary society is of a quite different character. In general, in its most developed form, it ignores differences of age, sex, and clan. There are, however, diversities in the constitution of the various organizations that may be called voluntary;[881] conditions of membership and functions vary.
