Classifying Madness examines the conceptual foundations of the D.S.M., the main classification of mental disorders used by psychiatrists world-wide. It will be of interest to both mental health professionals and to philosophers interested in classification in science. The D.S.M. has become extremely controversial, and the possibility that there may be philosophical difficulties with it has become a commonplace in the mental health literature. Classifying Madness offers mental health professionals an opportunity to explore suspicions that there might be conceptual problems with the D.S.M. For philosophers, this book aims to contribute to debates in the philosophy of science concerning natural kinds, the theory-ladenness of classification, and the effect of sociological factors in science. These issues are normally approached via a consideration of the natural sciences and, as will be seen, approaching them via a consideration of psychiatry helps shed new light on old problems.

Résumé
This book is about the Diagnostic and Statistical Manual of Mental Disorders, more commonly known as the D.S.M. The D.S.M. is published by the American Psychiatric Association and aims to list and describe all mental disorders. Within its pages can be found diagnostic criteria for types of depression, types of schizophrenia, eating disorders, anxiety disorders, phobias, sleeping disorders, and so on. Also included are less familiar, and more controversial, conditions: Mathematics Disorder, Caffeine Intoxication, Nicotine Dependence, Nightmare Disorder. It must be admitted that the D.S.M. is not an exciting read. Its pages follow a standard format: Each disorder has a numerical code. This is followed by a description of the disorder, which includes information regarding prevalence, course, and differential diagnosis. Finally explicit criteria that patients must meet to receive the diagnosis are listed. These generally include lists of the symptoms that must be present, restrictions as to the length of time that the symptoms must have been troublesome, and clauses that state that the symptoms must not be better accounted for by some other condition.
