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.[25]
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.[26] 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.
The existence of the primitive coitus play or rite seems to me sufficiently proven. The only thing that is obscure is the energy and emphasis of the ritual play. It is well known that those primitive rites were often of very bloody seriousness, and were performed with an extraordinary display of energy, which appears as a great contrast to the well-known indolence of primitive humanity.
