Thomas Keneally, Schindler’s Ark

”The resistance claimed that ten thousand murders on a given day were within the capacity of Auschwitz Two. Then, for the Łódź area, there was the camp at Chelmo, also equipped according to the new technology. To write these things now is to state the commonplace of history. But to find them out in 1942, to have them break upon you from a June sky, was to suffer a fundamental shock, a derangement in that area of the brain in which stable ideas about humankind and its possibilities are kept.”
