A widespread consensus among historians, sustained over a long period of time following the initial work of William Shirer in the 1960s, maintains that Hitler was anti-clerical. This continues to be the mainstream position on Hitler's religious views and these views continue to be supported by quotations from the English translation of the "Table Talk". Michael Burleigh contrasted Hitler's with those in "Table Talk", suggesting that Hitler's real religious views were "a mixture of materialist biology, a faux-Nietzschean contempt for core, as distinct from secondary, Christian values, and a visceral anti-clericalism". Richard Evans also reiterated the view that Nazism was secular, scientific and anti-religious in outlook in the last volume of his trilogy on Nazi Germany, writing that "Hitler's hostility to Christianity reached new heights, or depths, during the war", citing the 1953 English translation of "Hitler's Table Talk 1941–1944."
