The Latent Sexual Period Criticized
This error in the theoretical conception is shown clearly in the so-called latent sexual period of childhood. Freud has remarked that the early infantile so-called sexual manifestations, which I now call the phenomena of the pre-sexual stage, vanish after a while, and only reappear much later. Everything that Freud has termed the "suckling's masturbation," that is to say, all those sexual-like actions of which we spoke before, are said to return later as real onanism. Such a process of development would be biologically unique. In conformity with this theory one would have to say, for instance, that when a plant forms a bud, from which a blossom begins to unfold, the blossom is taken back again before it is fully developed, and is again hidden within the bud, to reappear later on in the same form. This impossible supposition is a consequence of the assertion that the early infantile activities of the pre-sexual stage are sexual phenomena, and that those manifestations, which resemble masturbation, are genuinely acts of masturbation. In this way Freud had to assert that there is a disappearance of sexuality, or, as he calls it, a latent sexual period. What he calls a disappearance of sexuality is nothing but the real beginning of sexuality, everything preceding was but the fore-stage to which no real sexual character can be imputed. In this way, the impossible phenomenon of the latent period is very simply explained. This theory of the latent sexual period is a striking instance of the incorrectness of the conception of the early infantile sexuality. But there has been no error of observation. On the contrary, the hypothesis of the latent sexual period proves how exactly Freud noticed the apparent recommencement of sexuality. The error lies in the conception. As we saw before, the first mistake consists in a somewhat old-*fashioned conception of the multiplicity of instincts. If we accept the idea of two or more instincts existing side by side, we must naturally conclude that, if one instinct has not yet become manifest, it is present in nuce in accordance with the theory of pre-formation. In the physical sphere we should perhaps have to say that, when a piece of iron passes from the condition of heat to the condition of light, the light was already existent in nuce (latent) in the heat. Such assumptions are arbitrary pro-
