Systems-Centered Practice presents a series of papers that trace the development of the theory of living human systems between 1987 and 2002. As the theory develops, so do the methods and techniques that put it into practice. The book also describes in detail the connection between the hierarchy of defence modification and the specific phases of system development that determine readiness for change. The papers in this volume contribute to our knowledge of the permeability of the boundaries between clinical and social psychology through the investigation of living human systems, and of systems-centered group and individual therapy. The author's considerable body of work constitutes a blend of creativity and learning of the highest order.
