Kurt Schneider's book Clinical Psychopathology is the culmination of the Heidelberg school of thought. Sometimes referred to as "Schneider's textbook," it is a collection of papers about diagnostics and the classification of mental disorders rather than an exhaustive work on psychopathology akin to Karl Jaspers' General Psychopathology. Schneider's book remains important today, despite many recent advances in science and technology, because it deals with clinical psychopathology without losing sight of the essential differences between psychiatry and physical medicine. This paper discusses Schneider's life, the history of the book, the notable points of the papers it contains, why the book did not catch on in the United States, and its current significance.
