An Experiential Approach to Psychopathology, and the method it proposes, may be considered the result of convergence of classic phenomenological psychopathological concepts and updated clinical insights into patients’ lived experiences. It endorses three key principles: subjective phenomena are the quintessential feature of mental disorders; their qualitative study is mandatory; phenomenology has developed a rigorous method to grasp “what it is like” to be a person experiencing psychopathological phenomena. While the book is highly relevant for expert clinical phenomenologists, it is written in a way that will be readily understandable for trainees and young clinicians.
