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,[12] 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[13] is hardly tenable theoretically, from the standpoint of the Freudian theory of libido. If Abraham believes that through the withdrawal of the libido from the outer world the paranoid system or the schizophrenic symptomatology results, then this assumption is not justified from the standpoint of the knowledge of that time, because a mere libido introversion and regression leads, speedily, as Freud has clearly shown, into the neuroses, and, strictly speaking, into the transference neuroses, and not into dementia præcox. Therefore, the transference of the libido theory to dementia præcox is impossible, because this illness produces a loss of reality which cannot be explained by the deficiency of the libido defined in this narrow sense.
It affords me especial satisfaction that our teacher also,
