Ludwig Binswanger's Comments on Hermann Rorschach's Psychodiagnostik.

This article presents an introduction to Ludwig Binswanger's Comments on Hermann Rorschach's Psychodiagnostik, published in the International Journal of Psychoanalysis in 1923, after Rorschach's death in 1922. Binswanger, one of the most distinguished psychiatrists of the twentieth century and a close professional colleague and compatriot in the Swiss Psychiatric and Psychoanalytic Societies, was blazing new trails by incorporating turn-of-the-century phenomenology and experimental psychology into Swiss psychiatry. His comments, which have been noted for over 100 years but never before translated, are a critical review of Rorschach's monograph, highlighting the undeveloped status of the test theory and philosophical foundations. Binswanger's comments illuminate philosophical, conceptual and scientific pathways not taken in the development of the test following Rorschach's untimely demise.
