This textbook for psychotherapists and group therapists encourages the reader to reflect on their own group experiences throughout their life journey and to relate these insights to therapy processes. Psychological life and personal development always occur within networks. Analytical group therapy utilizes this and makes psychological processes visible that often remain unclear in individual treatments. Our understanding of human psychological development is transforming in light of neuroscientific findings and against the backdrop of the complex societal challenges of our time, evolving into a view of humans as social animals. We are witnessing a resurgence in group therapy and an openness to theories that emphasize our mutual dependence in a positive sense. Togetherness and solidarity can thus be practiced collectively, unleashing transformative power for change in individuals, but also for society. Many relatable examples, especially from therapeutic groups, illustrate this. Written for: Psychotherapists, group therapists, group leaders in the medical and social fields. About the Author: Dipl. Psych. Volker Münch, Psychological Psychotherapist in private practice in Munich. Teaching analyst, supervisor, and lecturer at MAP, Munich.
