Richard Hull, Jung’s translator, commented on Liber Novus when showed it in 1961, as explained in p.94 of the Reader’s Edition Introduction: “I’m not surprised Jung keeps it under lock and key!….The Red Book made a profound impression on me; there can be no doubt that Jung had gone through everything that an insane person goes through, and more. Talk of Freud’s self-analysis: Jung is a walking asylum in himself! The only difference between him and a regular inmate is his astounding capacity to stand off from the terrifying reality of his visions, to observe and understand what was happening, and to hammer out of his experience a system of therapy that works. But for this unique achievement he’s be as mad as a hatter.”
