The intellectual condition of savages which has been presented and established by the evidence both of observers and of institutions, may now be studied in savage myths. These myths, indeed, would of themselves demonstrate that the ideas which the lower races entertain about the world correspond with our statement. If any one were to ask himself, from what mental conditions do the following savage stories arise? he would naturally answer that the minds which conceived the tales were curious, indolent, credulous of magic and witchcraft, capable of drawing no line between things and persons, capable of crediting all things with human passions and resolutions. But, as myths analogous to those of savages, when found among civilised peoples, have been ascribed to a psychological condition produced by a disease of language acting after civilisation had made considerable advances, we cannot take the savage myths as proof of what savages think, believe and practice in the course of daily life. To do so would be, perhaps, to argue in a circle. We must therefore study the myths of the undeveloped races in themselves. These myths form a composite whole, so complex and so nebulous that it is hard indeed to array them in classes and categories. For example, if we look at myths concerning the origin of various phenomena, we find that some introduce the action of gods or extra-natural beings, while others rest on a rude theory of capricious evolution; others, again, invoke the aid of the magic of mortals, and most regard the great natural forces, the heavenly bodies, and the animals, as so many personal characters capable of voluntarily modifying themselves or of being modified by the most trivial accidents. Some sort of arrangement, however, must be attempted, only the student is to understand that the lines are never drawn with definite fixity, that any category may glide into any other category of myth.
