Sebastian reads Janet
Janet sits at a strange angle to the tradition — foundational and then nearly erased, recovered only when trauma theory needed a pre-Freudian warrant. What he saw that Freud did not hold onto was the body’s specific grammar of not-knowing: the hysterical symptom is not symbolic disguise but a literal encapsulation, a fragment of experience the nervous system could not integrate and so stored as somatic enactment. His concept of *idées fixes subconscientes* anticipated what later became dissociation, and his account of *psychological tension* — the economy of psychic energy available for synthesis — gave trauma theory a hydraulic model that Freud borrowed and then disavowed. Hillman’s lineage mostly bypasses him; the Jungian lineage occasionally acknowledges him as a precursor. The productive moment to read Janet is when you are trying to understand why depth work that stays imaginal sometimes fails bodies that are still enacting — when the soul-material is not symbolic but somatic, not interpreted but inhabited.
