“The extermination of the Jews has sometimes been seen as a kind of industrialized, assembly-line kind of mass murder, and this picture has at least some element of truth to it. No other genocide in history has been carried out by mechanical means - gassing - in specially constructed facilities like those in operation at Auschwitz or Treblinka. At the same time, however, these facilities did not operate efficiently or effectively, and if the impression given by calling them industrialized is that they were automated or impersonal, then it is a false one. Men such as Hess and Stangl and their subordinates tried to insulate themselves from the human dimensions of what they were doing by referring to their victims as 'cargo' or 'items.' Talking to Gerhard Stabenow, the head of the SS Security Service in Warsaw, in September 1942, Wilm Hosenfeld noted how the language Stabenow used distanced himself from the fact that what he was involved in was the mass murder of human beings: 'He speaks of the Jews as ants or other vermin, of their 'resettlement', that means their mass murder, as he would of the extermination of the bedbugs in the disinfestation of a house.' But at the same time such men were not immune from the human emotions they tried so hard to repress, and they remembered incidents in which individual women and children had appealed to their conscience, even if such appeals were in vain. The psychological strain that continual killing of unarmed civilians, including women and children, imposed on such men was considerable, just as it had been in the case of the SS Task Forces, whose troops had been shooting Jews in their hundreds of thousands before the first gas vans were deploted in an attempt not only to speed up the killing but also to make it somehow more impersonal.”

“Some judicial officials began to notice the unusual frequency of deaths among the inmates of institutions and some prosecutors even considered asking the Gestapo to investigate the killings. However, none went so far as Lothar Kreyssig, a judge in Brandenburg who specialized in matters of wardship and adoption. A war veteran and a member of the Confessing Church, Kreyssig became suspicious when psychiatric patients who were wards of the court and therefore fell within his area of responsibility began to be transferred from their institutions and were shortly afterwards reported to have died suddenly. Kreyssig wrote Justice Minister Gortner to protest against what he described as an illegal and immoral programme of mass murder. The Justice Minister's response to this and other, similar, queries from local law officers was to try once more to draft a law giving effective immunity to the murderers, only to have it vetoed by Hitler on the grounds that the publicity would give dangerous ammunition to Allied propaganda. Late in April 1941 the Justice Ministry organized a briefing of senior judges and prosecutors by Brack and Heyde, to try to set their minds at rest. In the meantime, Kreyssig was summoned to an interview with the Ministry's top official, State Secretary Roland Freisler, who informed him that the killings were being carried out on Hitler's orders. Refusing to accept this explanation, Kreyssig wrote to the directors of psychiatric hospitals in his district informing them that transfers to killing centres were illegal, and threatening legal action should they transport any of their patients who came within his jurisdiction. It was his legal duty, he proclaimed, to protect the interests and indeed the lives of his charges. A further interview with Gortner failed to persuade him that he was wrong to do this, and he was compulsorily retired in December 1941.”

“It is interesting that this thoroughness, which is a virtue, is often misunderstood. When someone says a thing has been done scientifically, often all he means is that it has been done thoroughly. I have heard people talk of the "scientific" extermination of the Jews in Germany. There was nothing scientific about it. It was only thorough. There was no question of making observations and then checking them in order to determine something. In that sense, there were "scientific" exterminations of people in Roman times and in other periods when science was not so far developed as it is today and not much attention was paid to observation. In such cases, people should say "thorough" or "thoroughgoing," instead of "scientific.”

“Recounting the experience of individuals brings home, as nothing else can, the sheer complexity of the choices they had to make, and the difficult and often opaque nature of the situations they confronted. Contemporaries could not see things as clearly as we can, with the gift of hindsight: they could not know in 1930 what was to come in 1933, they could not know in 1933 what was to come in 1939 or 1942 or 1945. If they had known, doubtless the choices they made would have been different. One of the greatest problems in writing history is to imagine oneself back in the world of the past, with all the doubts and uncertianties people faced in dealing with a future that for the historian has also become the past. Developments that seem inevitable in retrospect were by no means so at the time, and in writing this book I have tried to remind the reader repeatedly that things could easily have turned out very differently to the way they did at a number of points in the history of Germany in the second half of the nineteenth century and the first half of the twentieth. People make their own history, as Karl Marx once memorably observed, but not under conditions of their own choosing. These conditions included not only the historical context in which they lived, but also the way in which they thought, the assumptions they acted upon, and the principles and beliefs that informed their behavior. A central aim of this book is to re-create all these things for a modern readership, and to remind readers that, to quote another well-known aphorism about history, 'the past is a foreign country: they do things differently there.”

“Ribbentrop brushed aside the Jewish extermination events. He said that in the long view, historically, the Jews' extermination would always be a blot on German history, but that it was in a way attributable to the fact that Hitler had lost his sense of proportion and, because he was losing the war, went "wild" on the subject of the Jews. But the big historical issue was not that Jews had been exterminated but that Germany had really been oppressed and never given a chance.”

“Why? What is so wonderful about mass murder that nobody in the history of the world has ever fond any smarter solution to problems than killing everybody who doesn’t agree? Is that the limit of human intelligence?”

“What a host of little incidents, all deep-buried in the past -- problems that had once been urgent, arguments that had once been keen, anecdotes that were funny only because one remembered the fun. Did any emotion really matter when the last trace of it had vanished from human memory; and if that were so, what a crowd of emotions clung to him as to their last home before annihilation? He must be kind to them, must treasure them in his mind before their long sleep.”
