This study in the philosophy of psychiatrydeals with the concept `psychosis'. Methodologicallyit follows Wittgenstein's proposal to `dissolve'philosophical problems by studying the actual use ofthe relevant concepts. Philosophical problemsconcerning both identification of psychosis and themeaning of this concept are pointed out. The logicaldependencies between `psychosis' and `understanding'and between `understanding' and the concept ofperson are demonstrated. Studying theinterdependence of these concepts in the light ofthe actual uses of `madness' shows how the use of`psychosis' implies a radical loss of understanding.The status and legitimacy (...) of `psychosis' as a psychiatric concept is then demonstrated.

In this paper it is argued that bioethics has tended to emphasise: ‘high tech’ areas of medicine at the expense of ‘low tech’ areas such as psychiatry; problems arising in treatment at the expense of those associated with diagnosis; questions of fact at the expense of questions of value; and applied ethics at the expense of philosophical theory. The common factor linking these four ‘bioethical blind spots’ is a failute to recognise the full extent to which medicine is an ethical (...) as well as scientific discipline. Once this is acknowledged it leads to a full-field bioethics in which the different areas are mutually complementary. In particular, it paves the way for a fruitful two-way exchange between the more abstract aspects of philosophical theory and the contingencies of day-to-day clinical work. The arguments of the paper are illustrated with recent work on the abuse of psychiatry. (shrink)
