This book investigates the crisis of diagnostic validity in psychiatry and psychology by examining the failure of current classification systems to meet scientific standards. The authors, including Drozdstoj St. Stoyanov, Massimiliano Aragona, and Peter Zachar, curate a collection of essays from prominent thinkers in the fields of medicine and philosophy. They argue that the current period of extraordinary science necessitates a shift toward integrating philosophical and historical analysis into clinical practice to better address the limitations of existing diagnostic frameworks.

Experts in the field of philosophy of psychiatry recognize this work as a significant contribution to the ongoing discourse regarding the scientific foundations of mental health diagnostics. Readers frequently note the academic density of the prose, which is intended for professionals and scholars familiar with the intersection of clinical practice and philosophical inquiry.
