The current neuroscientific research in the field of emotion studies highlights a paradigm of scientific research best categorized as functional science. Though researchers use psychological constructs proposed by the late Carl Jung, there appears to be a "fear of Jung," that is, a professional fear of invoking Jung's name or his psychological research. One familiar with Jung's works notices similar terminology, ideas, and even conclusions. Current research in the cognitive neurosciences investigating memory, emotional imagery, and emotions, as well as the field of PTSD research, provides ample support for a neurological stratum to these emotional complexes. There is much empirical evidence for a serious reconsideration of Jung's contributions for a natural human scientific study of emotions. This work is an empirical exploration that considers the value for the psychology of emotions by applying Jung's contributions to a psychological understanding of emotional experience. This work also considers the personal, psychological, and historical background of Jung's complex doctrine: his personal complexes and trauma as delineated in his autobiography and from other biographers; and his occult fascination and doctoral thesis where there are precursory ideas for his complex doctrine influenced by the dissociationist approach of P. Janet, T. Ribold, and T. Flournoy. It also considers Jung's own writings about complexes and his inability to seriously consider his personal complexes as they impinge upon his memories of his childhood, hypnogogic visions, dreams, personal relations, neurosis, etc.; his introverted intuitive psychological type and the impact of this upon his understanding of the complexes; and his neglect to consider the neurological component of psychic experience. This work is an initial contribution to a psychological and neurological study of personal emotional experience.
