Why write another book on ethics? As practitioners we are involved both in the design and delivery of services to people with mental health problems. In common with all other professionals, our work has led to the experience of ethical dilemmas: typically, these have involved major confrontations, either with our col­ leagues or our consciences. This book, however, is not limited to a discussion of such major themes. Rather, we have tried to use a broader canvas: ethics, in our view, is really about the judgement of right and wrong in ordinary, everyday life. Ethics are highly personal: we fashion our own personal code from our experi­ ence of others, and from the 'tests' which bring meaning to our lives. Such experiences shape our individual values. We bring these codes and values to our work. We are not always aware of their influence in our dealings with people. Although we may not always be aware of it, all our actions pose an ethical question. Given that our work involves us in helping others to live ordinary, satisfying lives, this challenge heightens the intensity of our ethical dilemmas. This is most evident where our personal code conflicts with the implicit code of the health setting.
