If, as Carl Jung thought, God cannot dwell in a sick soul, a truly religious attitude presupposes health of mind. Jolande Jacobi, a Jungian analyst, has written this book for persons interested in the contribution that psychology can make to self-understanding. Developments within psychoanalysis over the last 75 years indicate that certain aspects of the psyche operate on subconscious and unconscious levels. These recesses or "dark corners" of the soul, besides constituting repressed aspects of one"s personality, also form the substrata in which are rooted many of life"s most enriching qualities, such as artistic sensibility, inspiration, and the intuitive faculties. Dr. Jacobi devotes a major portion of the book to an explanation of Jung"s concept of persona or masks.. the psychophysical attitude which in every individual functions as mediator between the inner and outer world. She is convinced that there is no inherent conflict between Christianity and psychology. The ability to probe and to understand the complexity of human nature can provide Christians with strength to bear and learn form the pain and tensions that life inflicts as the consequence of expulsion from paradise. Jolande Jacobi, until her death in 1973, was one of the foremost interpreters of Jungian psychology. Her books and articles on psychology, the problems of modern women, art therapy, religion, and education have appeared worldwide.
