"'The eighth volume in the series of Jung's collected works is in many ways the most important to date in terms of clarity and completeness. It is the answer to the frequent demand for ""a book which gives a reliable and comprehensive account of Jungian psychology"". Here is just such an account, not by a disciple, but by the master himself. Almost all the key ideas are here: the structure of the psyche, the nature of the psyche, of dreams, of spirit, the archetypes, the collective unconsciousness, etc. Many of the key ideas are more fully treated elsewhere, but for a coherent presentation of them all, it would be hard to find a better source book.' - Blackfriars"
