Philosophical ideas about the mind, brain, and behavior can seem theoretical and unimportant when placed alongside the urgent questions of mental distress and disorder. However, there is a need to give direction to attempts to answer these questions. On the one hand a substantial research effort in going into the investigation of brain processes and the development of drug treatments for psychiatric disorders, and on the other, a wide range of psychotherapies is becoming available to adults and children with mental health problems. These two strands reflect traditional distinctions between mind and body, and causal as opposed to meaningful explanations of behavior. In this book, which has been written for psychiatrists, psychologists, philosophers, and others in related fields, the authors propose a radical re-interpretation of these traditional distinctions. Throughout the discussions philosophical theories are brought to bear on the particular questions of the explanation of behaviors, the nature of mental causation, and eventually the origins of major disorders including depression, anxiety disorders, schizophrenia, and personality disorder.
