This chapter gives an illustrated overview of recent philosophical work on the concept of delusion. Drawing on a number of case vignettes, examples are given of the wide range of theories that has been advanced to explain this most challenging of experiences. Some have agreed with the philosophical founder of modern descriptive psychopathology, Karl Jaspers, that delusions are “ununderstandable.” The large majority, though, has sought to understand delusion in terms of aberrations of one kind or another either of beliefs or (...) of the grounds or preconditions for beliefs. As a project in understanding, these theories offer helpful insights. A further group of theories focuses on the agential aspects of delusion as reflected, for example, in their role in the insanity defense. Agential theories converge with the person-centered approaches of contemporary empirical and clinical work on delusion. Such approaches bring an additional level of complexity in the form of delusions that are not pathological but adaptive in the life of the person concerned. As such they show the challenge of understanding delusion to be a project not just of understanding but of mutual understanding. (shrink)

Values-Based Medicine (VBM) is the theory and practice of clinical decision-making for situations in which legitimately different values are in play. VBM is thus to values what Evidence-Based Medicine (EBM) is to facts. The theoretical basis of VBM is a branch of analytic philosophy called philosophical value theory. As a set of practical tools, VBM has been developed to meet the challenges of value diversity as they arise particularly in psychiatry. These challenges are illustrated in this paper by a case (...) study of the differential diagnosis between delusion and religious experience. In a traditional model of scientific medicine, such challenges would be expected to become less pressing with advances in medical science. Philosophical value theory suggests, to the contrary, that scientific progress, through opening up an ever-wider range of choices, will increasingly bring the full range and diversity of human values into play not just in psychiatry but in all areas of medicine. The future, then, for medicine, is an integrated model in which VBM and EBM are equal partners in a genuinelyhuman discipline. (shrink)

Three revolutions in psychiatry characterised the closing decade of the twentieth century: 1) in the neurosciences, 2) in patient-centred models of service delivery, and 3) in the emergence of a rapidly expanding new cross-disciplinary field of philosophy and psychiatry. Starting with a case history, the paper illustrates the impact of this third revolution - the new philosophy of psychiatry - on day-to-day clinical practice through training programmes and policy developments in what has become known as values-based practice. Derived from philosophical (...) value theory and phenomenology, values-based practice is a partner to evidence-based practice in supporting clinical decision-making in the highly complex environment of mental health care. The paper concludes by setting values-based practice in context with other potentially practical important areas of the new philosophy of psychiatry arguing that all three revolutions need to be brought together if psychiatry is to meet the challenges of the twenty-first century.

Values based practice (VBP) is a radical view of the place of values in medicine which develops from a philosophical analysis of values, illness and the role of ethical principles. It denies two attractive and traditional but misguided views of medicine: that diagnosis is a merely factual matter and that the values that should guide treatment and management can be codified in principles. But, in the work of KWM (Bill) Fulford, it goes further in the form of a radical liberal (...) view: that the idea of an antecedently good outcome should be replaced by that of a right process. That however leads to a dilemma as to whether it can account for its own normative status. Given that difficulty, why might one adopt the radical version? I sketch a possible motive drawing on Rorty’s rejection of authoritarianism which replaces objectivity with solidarity as the aim of judgement. But I argue that, nevertheless, this does not justify the rejection of the more modest particularist version of VBP. (shrink)
