It is quite obvious that the nature of totemism and exogamy could be most readily grasped if we could get into closer touch with the origin of both institutions. But in judging the state of affairs we must not forget the remark of Andrew Lang, that even primitive races have not preserved these original forms and the conditions of their origin, so that we are altogether dependent upon hypotheses to take the place of the observation we lack[146]. Among the attempted explanations some seem inadequate from the very beginning in the judgment of the psychologist. They are altogether too rational and do not take into consideration the effective character of what they are to explain. Others rest on assumptions which observation fails to verify; while still others appeal to facts which could better be subjected to another interpretation. The refutation of these various opinions as a rule hardly presents any difficulties; the authors are, as usual, stronger in the criticism which they practice on each other than in their own work. The final result as regards most of the points treated is a non liquet. It is therefore not surprising that most of the new literature on the subject, which we have largely omitted here, shows the unmistakable effort to reject a general solution of totemic problems as unfeasible. (See, for instance, B. Goldenweiser in the Journal of American Folklore XXIII, 1910. Reviewed in the Brittanica Year Book, 1913.) I have taken the liberty of disregarding the chronological order in stating these contradictory hypotheses.
