After thirteen printings and with nearly 100,000 copies in print since its publication twenty years ago, Boundaries Of The Soul has become recognized as THE classic introduction to Jung and the practice of Jung’s psychology. The book has been described as the clearest and most coherent exposition of Jung’s total thought, by Robertson Davies, and Alan Watts has called Dr. Singer one of the great masters of the art. Now, in a completely revised edition of Boundaries Of The Soul, Dr. Singer incorporates the latest developments in Jungian psychology over the last two decades, particularly in the areas of masculine/feminine relationships, the use of psychotherapeutic drugs, and the evolution of Jung’s concept and personality types and its application both clinically and in the world of business and industry. In addition, the case histories, so central to understanding many of Jung’s concepts, have been re-examined and revised where necessary to correspond to the spirit of today’s world. The updated edition of Boundaries Of The Soul should reaffirm the book’s long-standing reputation as the best introduction to Jung’s thought available.
