JUNG, Carl Gustav (1875-1961). Typed letter signed ("C. G. Jung"), to Miss Jeanie E. Hughes. Kusnacht, Zurich, 6 March 1937. 1 page, 4to (293 x 209 mm), on personal stationery, with original typed envelope. JUNG REPORTS ON A PATIENT'S PROGRESS TO AN AMERICAN STUDENT: "A woman can fill many gaps by her intuition and her eros, where a man needs solid knowledge. Therefore be careful with him." Jung sends a report to Jane ("Jeanie") Hughes, one of his American students who attended his workshop at Bailey Island, Maine in 1936. He reports on the treatment of Hughes' brother, which was completed by Dr. Carl Alfred Meier: "As you know your brother is returning to America now. He has done his work with Dr. Meier and I saw him just once. From that interview I had with him i was convinced that it was much better for him to work with a younger man, because he is so little prepared for psychological work that my influence would have been a bit too much for his rather delicate mental structure." Carl Alfred Meier was a Jungian psychologist scholar and the first president of the C. G. Hung Institute in Zurich. He was Jung's successor as Honorary Professor of Psychology at the Swiss Federal Institute of Technology in 1949, and later co-founded the Clinic and Research Center for Jungian Psychology in Zurichberg. Of Meier's treatment of Hughes' brother, Jung writes: "Quite recently he told me of a certain difficulty which consisted of the fact that things wouldn't go any deeper and kept to a superficial stratum...I concluded that there was a serious reason why things should not be pushed on for the time being and that the things that want to sleep shouldn't be artificially disturbed...I advised Dr. Meier not to press your brother." He concludes that further treatment is not advisable at this time: "Things have developed just as far as they could for the time being, but not far enough to make collaboration with you advisable. Of course minor help of practical nature would be possible, but I would not burden him with any serious responsibility. I would be afraid to increase feelings of inferiority which a man is quite likely to get in such matters where he clearly feels that one should be scientifically well equipped."
