ETHICS IN MEDICINEThe ethical dimension of medicine is diverse, complex and all-pervasive. Ethics lies at the heart of clinical practice: it defines what we do and how and why we do it . The processes of communication and dialogue about values are as fundamental to clinical medicine as are factual, scientific knowledge and rigorously defined processes of reasoning and analysis. Perhaps paradoxically, however, how to talk about ethics has always been a problem. While the scientific world has available to it a well developed, highly effective and tightly regulated literary culture this is not the case for ethics. Because ethical reflection and experience are not exhausted by formal logic and linear argument ethical discourse cannot always be encompassed by the conventions of scientific writing. This has been recognised traditionally in the humanities, where ethical issues have been explored using a variety of literary settings, especially through the medium of the novel. In medicine, ethical discussion has often sought to conform to the style of scientific writing and expression, and this has led to important insights. However, some key limitations have also emerged: in particular, it has been difficult to present in an effective manner diverse and contending points of view, to ensure the preservation of ambiguity, and to convey both the extent to which the ethical imagination is embedded within clinical practice and the complexity of the dynamic dialogues it inhabits.One of the tasks of ethics is clearly to find forms of expression appropriate to both its processes and its subject matter. The following essay, which seeks to show how ethical reflection often proceeds through dialogues representing multiple viewpoints, is an example of an attempt to extend the presentation of ethical issues in clinical medicine to include some of these features. The responses of readers will be welcomed, as will additional submissions on the subject of ethics that employ innovative literary forms.
