As long as psychiatric diagnosis and treatment rest on psychopathological investigation, the continuing improvement and sharpening of this tool of investigation must remain a prime concern to psychiatrists. This book is a guide to that technique; still irreplaceable, much of it is still as fresh as the day it was written and still a lively stimulus to others yet to come. -- E. W. Anderson, foreword to the 1963 English translation of General Psychopathology
Karl Jaspers (1883-1969), a founder of existentialism, studied law and medicine at the University of Heidelberg in Germany, and received his M.D. in 1909. He taught psychiatry and philosophy at the University of Heidelberg, and philosophy at the University of Basel in Switzerland. His books include Psychology of World Views, and Philosophy.
Karl Jaspers was only thirty when he amassed the data and expounded the methods and interpretations that give his Psychopathologie a place at the side of James' monumental Principles of Psychology. Like James, he later turned to philosophy. He certainly shared James' radically empirical spirit; he documented more systematically the challenge to the methodological imperialism to which psychopathology was subject in his day. -- Peter A. Bertocci Review of Metaphysics
