August 2, 1952 Dr. Ludwig von Mises 777 West End Avenue New York 25, N.Y. Dear Dr. von Mises: Thank you for arranging translation of the Kelsen b book. It is a challenging task. After spending three full days on the first nine pages I realize that the job will take me several II months. I think I can do a job which does "elsen justice. My great difficulty is that there is no German-English Philosophical Dictionary. Muret-Sanders is incompatible. Thus, it is hard for me to ascertain a F E W terms. For instance Erkenntnis. Is it cognition or knowledge ? Weturteil. Is it judgment of values? And what does Adler mean by uretilen and beurteilen? I am stuck there. Otherwise I manage. Some sentences are so long that they have to be dissolved into several phrases. An American, in 1952, would say much of this inshorter and fewer sentences. ( Which is not meant to be any criticism at all. ) I hope that you are enjoying a pleasant vacation. Faithfully, Fallen Williams Felix Wittmer 395 Grove Street Upper Montclair, N.J. Clean, remember me to Urs. you Wins.
