One can easily think that just as the above-mentioned Australian bushmen perform the coitus play in this manner the same performance could be enacted in another manner, and, indeed, in the form of fire production. Instead of through two selected human beings, the coitus was represented by two substitutes, by Purûravas and Urvaçi, by Phallus and Vulva, by borer and opening. Just as the primitive thought behind other customs is really the sacramental coition so here the primal tendency is really the act itself. For the act of fertilization is the climax—the true festival of life, and well worthy to become the nucleus of a religious mystery. If we are justified in concluding that the symbolism of the hole in the earth used by the Watschandies for the fertilization of the earth takes the place of the coitus, then the generation of fire could be considered in the same way as a substitute for coitus; and, indeed, it might be further concluded as a consequence of this reasoning that the invention of fire-making is also due to the need of supplying a symbol for the sexual act.[306] Let us return, for a moment, to the infantile symptom of boring. Let us imagine a strong adult man carrying on the boring with two pieces of wood with the same perseverance and the energy corresponding to that of this child. He may very easily create fire by this play. But of greatest significance in this work is the rhythm.[307] This hypothesis seems to me psychologically possible, although it should not be said with this that only in this way could the discovery of fire occur. It can result just as well by the striking together of flints. It is scarcely possible that fire was created in only one way. All I want to establish here is merely the psychologic process, the symbolic indications of which point to the possibility that in such a way was fire invented or prepared.
