Occultism and the Origins of Psychoanalysis traces the origins of key psychoanalytic ideas back to their roots in hypnosis and the occult. Maria Pierri follows Freud’s early interest in "thought-transmission," now known as telepathy. Freud’s private investigations led to discussions with other leading figures like Carl Jung and Sándor Ferenczi, with whom he held a "dialogue of the unconsciouses." Freud’s and Ferenczi’s work assessed how fortune tellers could read the past from a client, inspiring their investigations into countertransference, the analytic relationship, unconscious communication, and mother-infant relationality. Both Freud and Ferenczi tried in different ways to come close to understanding the infant’s occult link with the mother and their secret primal language: their research on thought transference may be identified as a matrix of the developments of current psychoanalysis. Pierri clearly links modern psychoanalytic practice with Freud’s interests in the occult using primary sources, some of which have never previously been published in English. Occultism and the Origins of Psychoanalysis will be of great interest to psychoanalysts in practice and in training, as well as academics and scholars of Freudian ideas, psychoanalytic theory, the history of psychology, and the occult. It is complemented by Sigmund Freud and The Forsyth Case: Coincidences and Thought-Transmission in Psychoanalysis.
