The author makes a distinction between Freud's notion of the "unconscious as instrument", which it is only possible to know about from derivatives in the context of a setting with specific and necessary conditions, and the notion of "countertransference"- the term that is often used in contemporary literature to describe a direct transmission of conscious or preconscious experience, which is more akin to "thought transference". The author posits that the derivatives of the patient's unconscious happenings in the session, as they are experienced in the analyst's "unconscious as instrument", can take different pathways. The author goes on to specifically discuss the bodily pathway of the unconscious derivatives, suggesting that these derivatives indicate the primitive nature of what is being emitted and the state of the receiver. The body acts as a concrete container for the "excess", which at that point in time cannot be transformed and understood, is beyond symbolization, and along with other indices, will require further psychic work.
