In this passage Freud plainly touches upon the question whether the well-known longing for reality of the paranoic dement (and the dementia præcox patients),[245] to whom I have especially called attention in my book, “The Psychology of Dementia Præcox,”[246] is to be traced back to the withdrawal of the “libidinous affluxes” alone, or whether this coincides with the so-called objective interest in general. It is hardly to be assumed that the normal “fonction du réel” (Janet)[247] is maintained only through affluxes of libido or erotic interest. The fact is that in very many cases reality disappears entirely, so that not a trace of psychological adaptation or orientation can be recognized. Reality is repressed under these circumstances and replaced by the contents of the complex. One must of necessity say that not only the erotic interest but the interest in general has disappeared, that is to say, the whole adaptation to reality has ceased. To this category belong the stuporose and catatonic automatons. I have previously made use of the expression “psychic energy” in my “Psychology of Dementia Præcox” because I was unable to establish the theory of this psychosis upon the conception of the displacement of the affluxes of libido. My experience, at that time chiefly psychiatric, did not enable me to understand this theory. However, the correctness of this theory in regard to neuroses, strictly speaking the transference neuroses, was proven to me later after increased experience in the field of hysteria and compulsion neuroses. In the territory of these neuroses it is mainly a question whether any portion of the libido which is spared through the specific repression becomes introverted and regressive into earlier paths of transference; for example, the path of the parental transference.[248] With that, however, the former non-sexual psychologic adaptation to the environment remains preserved so far as it does not concern the erotic and its secondary positions (symptoms). The reality which is lacking to the patients is just that portion of the libido to be found in the neurosis. In dementia præcox, on the contrary, not merely that portion of libido which is saved in the well-known specific sexual repression is lacking for reality, but much more than one could write down to the account of sexuality in a strict sense. The function of reality is lacking to such a degree that even the motive power must be encroached upon in the loss. The sexual character of this must be disputed absolutely,[249] for reality is not understood to be a sexual function. Moreover, if that were so, the introversion of the libido in the strict sense must have as a result a loss of reality in the neuroses, and, indeed, a loss which could be compared with that of dementia præcox. These facts have rendered it impossible for me to transfer Freud’s theory of libido to dementia præcox, and, therefore, I am of the opinion that Abraham’s investigation[250] is hardly tenable
