How does art therapy work? What is special about it as a psychotherapeutic approach? The author of the book addresses these questions. She argues that the topic of 'symbol and symbolization processes' forms the core of a theory of art therapy. Art therapists work with visual images and sculptures, the raw material of symbolization. The concept of the symbol is central in both art and psychoanalysis. In art therapy, a synthesis of both areas occurs. A new form of relationship is created between the patient, the artistic work, and the therapist. Important themes arise that the author discusses: What distinguishes an artist from a patient who works with artistic media? What is healing in art? Can art also emerge in art therapy? And what role does the art therapist play in this? Case studies and images from clinical practice complement the presentations.
