In the months before publication, Jung read and corrected Bennet’s book in typescript, making this the only biography of Jung to have been written during the subject’s life with his supervision and approval. Thanks to Bennet’s unique opportunities to hear Jung’s personal perspective—on subjects from Freud to Hitler, and including a valuable correspondence about Aion, regarded as Jung’s most "difficult" book—C.G. Jung promises to shed new light for today’s scholars on Jung’s work and on the man himself.
