possess a very complex social organization, but are, nevertheless, only slightly superior, on the whole, to primitive peoples. Thus, the various phases of totemic culture may develop in relative independence of one another, even though they are in constant interaction. This is true particularly in the sense that the more developed totemic customs and cults occur even on low cultural levels, whereas, on the other hand, they more and more disappear with the progress of culture. 2. THE STAGES OF TOTEMIC CULTURE. We cannot undertake to describe the extraordinarily rich external culture attained by those groups of peoples who may, in the main, be counted as belonging to the domain of totemism. This is the task of ethnology, and is not of decisive importance for folk psychology. True, in the case of primitive man, the conditions of external culture were described in some detail. This was necessary because of the close connection between these conditions and the psychical factors fundamental to all further development. The beginning of the totemic period marks a great change. New forces now come into play, such as are not to be found among the universal motives that have controlled the life of man from its very beginning. Of these forces there is _one_ in particular that should be mentioned--one that is practically lacking among primitive tribes. This consists in the reciprocal influences exercised upon one another by peoples who occupy approximately the same plane of culture but who nevertheless exhibit certain qualitative differences. Migrations are also an important factor in the totemic age, as well as is the tribal warfare with which migrations are connected.
