'Ex definineto, the id is the agency that does not possess any knowledge of the external world and does not keep any direct contact with the outer world. These occur exclusively via the ego. When strictly adhering to this definition, I must state that I have never found an id tendency or impulse in my patients.' In contrast the repressed unconscious appears to possess fairly accurate knowledge of reality and the possibilities existing in it. Ex definitione such knowledge is the exclusive due of the ego. The author comes therefore to the conclusion that the repressed portion of the id is not pure id but an ego id, just like the undifferentiated phase in the early part of psychic life. The primary process is obviously the primitive way of psychic functioning of this archaic forerunner of the psychic personality, the undifferentiated ego-id; it seems to characterize the ego aspect of the undifferentiated phase.
