INTRODUCTION (PREFACE TO THE FIRST AND SECOND GERMAN EDITIONS) THE author’s purpose in the present work[1] has been to give an exact historical and psychological picture of Luther’s personality, which still remains an enigma from so many points of view. He would fain present an accurate delineation of Luther’s character as seen both from within and from outside throughout the history of his life and work from his earliest years till his death. He has, however, placed his hero’s interior life, his spiritual development and his psychic history well in the foreground of his sketch.
