where the libido was still partly in the function of nutrition. By a regression to the presexual material the libido becomes quasi-desexualized. But as the incest prohibition signifies only a temporary and conditional restriction of the sexuality, thus only that part of the libido which is best designated as the incestuous component is now pushed back to the presexual stage. The repression, therefore, concerns only that part of the sexual libido which wishes to fix itself permanently upon the parents. The sexual libido is only withdrawn from the incestuous component, repressed upon the presexual stage, and there, if the operation is successful, desexualized, by which this amount of libido is prepared for an asexual application. However, it is to be assumed that this operation is accomplished only with difficulty, because the incestuous libido, so to speak, must be artificially separated from the sexual libido, with which, for ages, through the whole animal kingdom, it was indistinguishably united. The regression of the incestuous component must, therefore, take place, not only with great difficulty, but also carry with it into the presexual stage a considerable sexual character. The consequence of this is that the resulting phenomena, although stamped with the character of the sexual act, are, nevertheless, not really sexual acts de facto; they are derived from the presexual stage, and are maintained by the repressed sexual libido, therefore possess a double significance. Thus the fire boring is a coitus (and, to be sure, an incestuous one), but a desexualized one, which has lost its immediate sexual worth, and is, therefore, indirectly useful to the propagation of the
