Do you want to make life for yourself and your trusty students a plague and be an object of censure to your colleagues? You intend even to keep commitments of writing papers—e.g., for Sommerfeld??[2] You’re going too far. If Shakespeare had lived under today’s conditions, he probably would have preferred to modify his little saying “At lovers’ perjuries, They say, Jove laughs,”[3] which is really a little severe, to “At broken re- view commitments, . . .” And then you tell me that, according to our friend Oppen- heim, I was supposed to have found God knows what kind of fine things.[4] But none of that is true. The modest insinuation I made to him about the matter, about which I told you at the Grunewald Lake, has blown dangerously out of proportion in his fertile imagination! Quantum theory kindles sentiments in me, very similar to yours. One should actually be ashamed of the successes because they have been won by the Jesuit axiom: “Let not thy left hand know what thy right hand doeth.”[5] I don’t view the political situation as pessimistically as you do. The conditions are harsh but will never be carried through to reality.[6] They will serve to satisfy the eye rather than the stomach of the “enemy.” Ludendorff was undoubtedly much worse than the Parisians. The French act like that out of fear but Ludendorff has Napoleonic yearnings.[7] The hardships from French mistakes will be mellowed by a never-to-fail sloppiness, just as in my erstwhile fatherland Austria.[8] Ultimately, the menace of Germany will dissipate like a puff of smoke together with the ene- mies’ unity, whereby a certain hysteresis does prevail. Is a hardcore x-brother and determinist allowed to say, teary-eyed, that he had lost faith in people? It is precise- ly people’s impulsive behavior in political affairs today that is suited to making be- lief in determinism very much alive. I am convinced that what the next few years bring will be far less difficult than the experiences of past years. With cordial greetings to you and your wife, also from my wife,[9] yours, Einstein. Haber’s application of your theory to monovalent metals is amazing.[10] 57. From Leonhard Grebe Bonn, 6 June 1919 Dear Professor, Unfortunately, the political situation does not permit me and my collaborator to come to Berlin, as we had intended, during the Pentecost holidays.[1] For now, I must consequently forgo using the microphotometer constructed by Freundlich.[2] Our researches have meanwhile developed to the extent that a microphotometric
