(A moral with a personal application.) The reason that most morals lead to skewed results seems to me to be that they regard the easily observable progress of the intellectual as divinely ordained, unique and victorious, instead of saying: it is one of many paths that lead into the abyss, and: we do not know whether there are any paths that do not lead into the abyss. I remain, with best regards and the hope that I have completely converted you (which the probably unclear wording might at best have hindered), your, Teddy 105. From Josef Winternitz[1] Berlin, 13 December 1927 Dear Professor, A Polish physicist, Mr. L. Infeld,[2] has, he informs me, sent an article titled “On the Field Theory of Electricity and Gravitation” to your address. I know Mr. Infeld to be a very talented theoretical physicist, because in 1920/21, together with Messrs. Leo Szilard and Grolmann,[3] we both participated in a group that worked through the theory of relativity. I am convinced that Mr. Infeld would not have sent his article[4] to you if he did not believe that he has obtained some essential results. Since Mr. Infeld quite correctly assumes that you receive a large number of such articles, and that it is impossible for you to read through all of them carefully, [he] has requested me to make you aware of his work. He sent it to your address about a month ago. Dear Professor, I would be very grateful to you if you could reply or have a reply sent, as to whether the article reached you, since my friend is waiting with the greatest eagerness to hear your opinion of it. My address is: Dr. Winternitz, c/o Mrs. v. Gi[lar], Berlin W15, Pariserstr. 25/26, telephone Oliva 5545 (I am, however, usually at home only in the early mornings and late evenings). With kind regards to you and your wife, yours sincerely, Dr. Josef Winternitz
