Carl Gustav Jung never produced a systematic treatment of his own work - he was always moving forward. His assistant-of-many-decades, Carl Alfred Meier, made it his life-task to gather and present in detail the various aspects of Jung's far-reaching discoveries. This final volume of Meier's work addresses the human personality in its encounters between consciousness and the unconscious, a process referred to as individuation. In describing such encounters, the author extensively explains the notion of Jung's psychological types.

“… Meier has a gift of expressing the most complex concepts simply … [this book] will not only enrich the natural scientist but act as an unfailing guide to the increasing hordes of lost people in search of a soul, in a world that has forfeited its meaning.” — Sir Laurens van der Post
