3 8 6 D O C U M E N T S 4 2 2 , 4 2 3 M A R C H 1 9 2 9 422. To the Prussian Academy of Sciences Berlin, 7 March 1929 With regard to your letters of 28 February and 6 March, I hereby inform you that in response to a request from me, the Emergency Association for German Science has granted a stipend to Dr. Lanczos,[1] a Privatdozent in Frankfurt am Main, from November 1928–1929 for the purpose of pursuing joint scientific work. Concerning the other questions asked, I have no comments to make.— Respectfully yours, A. Einstein 423. To Hans Stürmer [Berlin,] 7 March 1929 Dear Mr. Stürmer, It will probably not be doubted by any reasonable person that every event is con- sistent and that the terminology for describing it is related physically and psychi- cally only to the modes of perceiving or conceiving the individual occurrences.[1] What I objected to was only the somewhat primitive hypothetical construct with which you tried to conceive of mental events physically. For example, the repre- sentation of a concept or any other content of consciousness by a cell or a group of cells [with] an associative connection through a nerve fiber, etc., and also the use of the word “energy” in an ambiguous sense. Insofar as these metaphors make no claim to be anything but crude comparisons to the enforcement of purely causal thinking, they are unobjectionable. But the illusion that one has now understood the actual processes must not be awakened.— However, this does not prevent me from fully recognizing your book’s[2] wealth of ideas and the sound conception of life it represents. Respectfully yours,
