ABSTRACT
The three quotations that head this chapter reflect the dangers, uncertainties and ambiguities that exist when we devise complex systems for purposes of management, whether they be in health care, education, criminal justice or penal administration. Readers who have journeyed so far and addressed the first three chapters of this book will, I trust, have come to understand that engagement with the great variety of disordered behaviours is a complex task if we are to bring about humane and effective management. The material I provide in this chapter can serve only as an introduction to this aspect. More detailed information will be found in the references and citations for further reading.
