Sigmund Freud's psychoanalysis has profoundly influenced the understanding of the human psyche. Together with his companions Alfred Adler and Carl Gustav Jung, he left a lasting impact on contemporary thought. The effects of this intellectual revolution can be seen even in everyday life. Since then, depth psychology has branched out in many directions: little of what the founding fathers articulated has remained intact; much has been discarded, expanded, rediscovered, and redefined. The central role of charismatic therapists and researchers has shifted to favor the patient and their developmental possibilities. This book provides a well-founded overview of the highly dynamic field of depth psychology: the common foundations, the key representatives, and the central concepts.
