Or are they necessary, individu- ally unalterable givens by the very nature of human thought? I personally back the former standpoint also advocated, e.g., by Helmholtz and Poincaré, whereas it appears to me that Kant’s standpoint was more the latter. In great respect. 375. To Romain Rolland [Berlin, on or before 30 September 1922] Dear Romain Rolland, Zangger and I are happily sitting together and thinking of you. I am feeling well. I have the chance to travel to Japan in a few days. Hoping to see you soon, happy and healthy, I am, with cordial greetings, yours, A. Einstein. 376. To Pierre Comert Berlin, 1 October 1922 Dear Mr. Comert, I took a lot of trouble to find someone to represent me but a series of unhappy circumstances prevented me from bringing the business to a good conclusion. Ini- tially I had the intention of having myself represented by my friend the psycholo- gist Wertheimer, professor at the University of Berlin, but he was on vacation in Prague and he is so unsociable that he hesitated a long time to accept. He let me wait like this so long and so thoroughly that in the end it was too late. Then I sought out Mr. Troeltsch, but he, too, was away on vacation, so today I have to leave with- out having terminated this affair. Please do not attribute this failure to ill intentions on the part of my friends here but to the fact that none of the persons I had envisaged were present in Berlin and I am persuaded all were would have been appointable to replace me. With amicable regards, yours, A. Einstein.
