What is required of the interpreter of disordered minds and what can we learn from the process? Jonathan Glover's book focuses on human interpretation and its role in psychiatry. His hope is that a more careful and sensitive exploration of minds that are very different from our own, will assist us to answer a range of important questions about human agency, identity and responsibility. In this commentary I will focus on the process and purpose of interpretation and expand on some of the moral issues that arise out of the interpretive challenges posed by mental disorders.
