In "The Inner World Outside: Object Relations Theory and Psychodrama", he explores the connections between the theories of Jacob Levi Moreno, the creator of psychodrama, and Sigmund Freud, the creator of psychoanalysis, combining them with the ideas of other psychotherapy approaches. The book is brilliantly usable in the training and practice of all professionals in the field of psychotherapy and mental health. At the same time, it can be of invaluable help to people working in the fields of psychodrama, psychoanalysis and the humanities. The guidance it can offer to any self-reflective person is also beyond doubt.
