1 5 6 D O C U M E N T S 1 4 8 , 1 5 0 F E B R U A R Y 1 9 2 8 148. To Heinrich Meng[1] Berlin, 15 February 1928 Dear Dr. Meng, Though I admire Freud’s brilliant achievement, I cannot resolve to intervene in the present case.[2] I cannot persuade even myself regarding the substantive truth of Freud’s theory, not to mention make a judgment that would influence others.[3] Furthermore, I would like to point out that it seems questionable whether the achievement of a psychologist like Freud falls within the domain of the Nobel Prize in Medicine, which is probably the only one that can be considered. Respectfully yours, A. Einstein 149. From Heinrich Zangger [Zurich, ca. 16 February 1928][1] [Not selected for translation.] 150. To Ilse Kayser-Einstein and Margot Einstein [Berlin,] Saturday [18 February 1928] My dears, Every day, we flip coins to decide whether we should go or not.[1] But since the result is different every time, we don’t know what to do. In any case we won’t visit you, so that science will not be peeved.[2] I was in Holland to say a final farewell to Lorentz.[3] One grows solitary in order to better adapt oneself for the departure. I am glad to hear that Ilse is getting stronger[4] and that Margot has risen to the level of an Amazon. If she isn’t good, we’ll also exhibit her nose under a big lens. Enough for today. I have to flip coins again, to be sure that nothing is neglected. Best regards from your Albert
