Explaining Hitler is a 1998 book by Ron Rosenbaum that compiled a number of different theories about why Adolf Hitler was the way he was, updated recently with new information.
Hitler did not escape the bunker in Berlin but, seven decades later, he has managed to escape explanation in ways both frightening and profound. Explaining Hitler is an extraordinary quest, an expedition into the war zone of Hitler theories. This is a passionate, enthralling book that illuminates what Hitler explainers tell us about Hitler, about the explainers, and about ourselves.
Vice recently interviewed Rosenbaum about the book.
Oh my God, there are so many terrible psychological attempts to explain Hitler. I think the subject brings out the worst in talk show psychologists. There’s a lot of ‘psychopathic narcissism’ among those psychologizing Hitler. The examples in my book were two psychoanalysts-one wanted to claim that Hitler became Hitler because he was beaten by his father, and the other psychoanalyst was equally determined to believe that Hitler had a malignant mother who was over-protective. As if everyone who has an over-protective mother or abusive father turns into Hitler. If everyone who has been struck by their father turned into Hitler we would be in a lot more trouble than we are.
