This book contains two essays written by Jung himself. They cover almost all of the major parts of Jungs work and clear up a lot of misconceptions that arose over his theories. I would highly recommend this book as an introduction to Jungs theories. It is ideal if you do not have the time to wade through his many other lengthy writings. It would also be a valuable reference to anyone already familiar with Jung, as it clarifies much about his work. It is an intellectual read, it does not give a simplistic description of theories as is sometimes found when other authors summarise Jungs ideas. Get to know the real meaning behind Jungs theories as written by the man himself.
