I analyze the historical background and philosophical considerations of Karl B眉hler and his student Karl Popper regarding the crisis of psychology. They share certain Kantian questions and methods for reflection on the state of the art in psychology. Part 1 outlines B眉hler鈥檚 diagnosis and therapy for the crisis in psychology as he perceived it, leading to his famous theory of language. I also show how the Kantian features of B眉hler鈥檚 approach help to deal with objections to his crisis diagnosis and to aspects of his linguistic theory. Part 2 turns to Popper鈥檚 dissertation, completed in 1928 under B眉hler. I analyze Popper鈥檚 disapproval of Schlick鈥檚 physicalism in psychology, as well as Popper鈥檚 attempt to extend B眉hler鈥檚 Kantian strategy to the domain of the psychology of thinking. In conclusion, I indicate how these approaches to the crisis in psychology differ from Thomas Kuhn鈥檚 notions of crisis and revolution, which are still all too popular in current philosophical discussions of psychology.
