In order to give a semblance of intelligibility to this duality, so strange for us, the primitive has invented myths which, it is true, explain nothing and only shift the difficulty, but which, by shifting it, seem at least to lessen the logical scandal. With slight variations of detail, all are constructed on the same plan: their object is to establish genealogical connections between the man and the totemic animal, making the one a relative of the other. By this common origin, which, by the way, is represented in various manners, they believe that they account for their common nature. The Narrinyeri, for example, have imagined that certain of the first men had the power of transforming themselves into beasts.[390] Other Australian societies place at the beginning of humanity either strange animals from which the men were descended in some unknown way,[391] or mixed beings, half-way between the two kingdoms,[392] or else unformed creatures, hardly representable, deprived of all determined organs, and even of all definite members, and the different parts of whose bodies were hardly outlined.[393] Mythical powers, sometimes conceived under the form of animals, then intervened and made men out of these ambiguous and innumerable beings which Spencer and Gillen say represent "stages in the transformation of animals and plants into human beings."[394] These transformations are represented to us under the form of violent and, as it were, surgical operations. It is under the blows of an axe or, if the operator is a bird, blows of the beak, that the human individual was carved out of this shapeless mass, his members separated from each other, his mouth opened and his nostrils pierced.[395] Analogous legends are found in America, except that owing to the more highly developed mentality of these peoples, the representations which they employ do not contain confusions so troublesome for the mind. Sometimes it is a legendary personage who, by an act of his power, metamorphosed the animal who gives its name to the clan into a man.[396] Sometimes the myth attempts to explain how, by a series of nearly natural events and a sort of spontaneous evolution, the animal transformed himself little by little, and finally took a human form.[397]
