ABSTRACT
A starting point was the concept of the unconscious and the unconscious as a structure requires an analysis of the numerous elements of which it is comprised. These include the object. Karl Abraham was an emblematic author in clarifying the chaotic and unpredictable unconscious and the unstable object. His strengths resided in the breadth of his interests, his solid humanistic training, psychoanalytic theory, and his incessant clinical work consisting of extremely diverse cases. He maintained that there was a direct relationship between oral frustration and schizophrenia, and related the latter to a regression to a narcissistic infantile stage. The incorporation of the aggressive drive in the structure of obsessional neurotics and its influence on object relations through repression was another of Abraham's greatest contributions. His intuitions regarding mourning and the reinforcement of the libido after the trauma of object-loss have been extensively confirmed by clinical experience.
