A collection of classical writings of Swiss psychologist Carl G. Jung, an influential thinker and the founder of analytical psychology. Written at intervals over a span of fourteen years, these selected articles and pamphlets contain many fascinating ideas that have become widely accepted psychological concepts nowadays, but had just started to develop at the time when the book was written. For instance, this is where Dr. Jung's ideas of introversion and extroversion, a contribution of vital importance to psychology, appeared for the very first time. Other topics explored include the concept of the unconscious, the study of psychological types, and the psychology of dreams. (Cao Yuqing)
