In extending his conception of the unconscious from that which had been gained through his initial collaboration with Freud, Jung in his early career began to see that a “rationally explicable unconscious” is only a top layer, the material in which has been made unconscious artificially (e.g., through repression). He went on to call this the “personal unconscious,” beneath which he says is an “absolute unconscious which has nothing to do with our personal experience.” This is what Jung called the “collective unconscious” which can operate independently of the conscious mind “untouched – and perhaps untouchable – by personal experience” (Jung 1931/1991: 148).
