How does a person experience emotions? What is the relationship between the experiential and biological dimensions of emotions? How do emotions figure in a person's relation to the world and to other people? How do emotions feature in human vulnerability to mental illness? Do they play a significant role in the fragile balance between mental health and illness? If emotions are in fact significant, how are they relevant for treatment? Emotions and personhood are important notions within the field of mental health care. What they are, and how they are related though, is less evident. This book provides a framework for understanding this relationship. The authors argue for an account of emotions and personhood that attempts to understand human emotions from the combined approach of philosophy and psychopathology, taking its models particularly from hermeneutical phenomenology and from dialectical psychopathology. Within the book, the authors develop a basic set of concepts for understanding what emotional experience means for a human person, with the assumption that human emotional experience is fragile - a fact which entails vulnerability to mental disturbance. Drawing on research from psychiatry, psychopathology, philosophy, and neuroscience, the book will be valuable for both students and researchers in these disciplines, and more broadly, within the field of mental health.
