The sudden appearance of the term “desexualization” in The Ego and the Id is considered as a marker of the subtle, almost unnoticeable changes that occurred in Freud's thinking after 1920. The strict dichotomy between life and death drives posed a series of new problems that force Freud to invoke a “desexualized libido” in order to restore some fluidity in the psychic apparatus. But the mechanism of desexualization was difficult to describe and Freud seems to resort to a circular explanation. In the end, the restored dialectics between Eros and the death drive, thanks to desexualization, force Freud to invoke a split in the ego itself.
