With this alteration in the libido conception, certain parts of our terminology need revision as well. As we know, Abraham has undertaken the experiment of transferring the Freudian libido theory to dementia præcox and has conceived the characteristic lack of rapport and the cessation of the function of reality as autoerotism. This conception needs revision. Hysterical introversion of the libido leads to autoerotism, since the patient’s erotic afflux of libido designed for the function of adaptation is introverted, whereby his ego is occupied by the corresponding amount of erotic libido. The schizophrenic, however, shuns reality far more than merely the erotic afflux would account for; therefore, his inner condition is very different from that of the hysteric. He is more than autoerotic, he builds up an intra-psychic equivalent for reality, for which purpose he has necessarily to employ other dynamics than that afforded by the erotic afflux. Therefore, I must grant to Bleuler the right to reject the conception of autoerotism, taken from the study of hysterical neuroses, and there legitimate, and to replace it by the conception of autismus.[268] I am forced to say that this term is better fitted to facts than autoerotism. With this I acknowledge my earlier idea of the identity of autismus (Bleuler) and autoerotism (Freud) as unjustified, and, therefore, retract it.[269] This thorough revision of the conception of libido has compelled me to this. From these considerations it follows necessarily that the descriptive psychologic conception of libido must be given up in order for the libido theory to be applied to dementia præcox. That it is there applicable is best shown in Freud’s brilliant investigation of Schreber’s phantasies. The question now is whether this genetic conception of libido proposed by me is suitable for the neuroses. I believe that this question may be answered affirmatively. “Natura non fecit saltum”—it is not merely to be expected but it is also probable that at least temporary functional disturbances of various degrees appear in the neuroses, which transcend the boundaries of the immediate sexual; in any case, this occurs in psychotic episodes. I consider the broadening of the conception of libido which has developed through the most recent analytic work as a real advance which will prove of especial advantage in the important field of the introversion psychoses. Proofs of the correctness of my assumption are already at hand. It has become apparent through a series of researches of the Zurich School, which are now published in part,[270] that the phantastic substitution products which take the place of the disturbed function of reality bear unmistakable traces of archaic thought. This confirmation is parallel to the postulate asserted above, according to which reality is deprived, not merely of an immediate (individual) amount of libido, but also of an already differentiated or desexualized quantity of libido, which, among
