Der Kampf um das Kausalgesetz in der jüngsten Physik. Brauchschweig: Vierweg 1929, p. v.  . Es ist wohlbekannt, dass die Physik unserer Tage unter dem Einfluss der Tatsachen der Atomphysik an der Durchführbarkeit einer strengen Kausa- lität ernsthaft zweifelt. Da ist es wohl berechtigt, wenn ein Fachphilosoph, dem man in seltenen Masse Beherrschung der philosophischen Literatur, Selbständigkeit des Denkens und Kenntnis der wesentlichen einschlägi- gen physikalischen Tatsachen und Erklärungsversuchen nachrühmen darf, das Problem analysiert. Möge das Büch-lein dazu beitragen, die von den Besten unserer Tage erstrebte Annäherung physikalischer und philosophi- scher Denkarbeit zu fördern.— Mit vorzüglicher Hochachtung  Bergmann 1929.

[2] Einstein also discussed strict causality in scientific theorizing in Doc. 156. He expressed his strong desire to hold on to that notion in correspondence (see Docs. 180 and 186) and in a discussion of religiosity (Doc. 33). [3] In preparing to publish Bergmann 1929, Vieweg & Sohn asked Einstein if he would write a few remarks that it could use in its advertising (Abs. 936). Bergmann had originally sent his manuscript to Robert Weltsch, the editor of Jüdische Rundschau, who forwarded it to potential publishers, though without success. Weltsch then wrote to Einstein to ask his opinion on Bergmann’s work and to ask whether he would consider recommending the text to a publisher himself (Abs. 746). Einstein quickly replied that he would be happy to recommend it to Kantstudien (Abs. 749). However, after reading it more thoroughly, Einstein wrote to Weltsch with more enthusiasm to say that, besides being published in a journal, it should perhaps be made available as a book as well (Abs. 776). Weltsch transmitted Einstein’s letter to Vieweg & Sohn (Abs. 791), and Bergmann himself wrote gratefully to Einstein shortly thereafter (Abs. 808). [3] [2]
