Beware of analogies: for millenia they corrupted medicine, and it may be their fault that today's pedagogical systems are so numerous, and after thre… - Primo Levi

"There is no rationality in the Nazi hatred: it is hate that is not in us, it is outside of man.. We cannot understand it, but we must understand from where it springs, and we must be on our guard. If understanding is impossible, knowing is imperative, because what happened could happen again. Consciences can be seduced and obscured again - even our consciences. For this reason, it is everyone duty to reflect on what happened. Everybody must know, or remember, that when Hitler and Mussolini spoke in public, they were believed, applauded, admired, adored like gods. They were "charismatic leaders" ; they possessed a secret power of seduction that did not proceed from the soundness of things they said but from the suggestive way in which they said them, from their eloquence, from their histrionic art, perhaps instinctive, perhaps patiently learned and practised. The ideas they proclaimed were not always the same and were, in general, aberrant or silly or cruel. And yet they were acclaimed with hosannas and followed to the death by millions of the faithful."

They are the typical product of the structure of the German Lager: if one offers a position of privilege to a few individuals in a state of slavery, exacting in exchange the betrayal of a natural solidarity with their
comrades, there will certainly be someone who will accept. He will be withdrawn from the common law and will become untouchable; the more power that he is given, the more he will be consequently hateful and
hated. When he is given the command of a group of unfortunates, with the right of life or death over them, he will be cruel and tyrannical, because he will understand that if he is not sufficiently so, someone else, judged more suitable, will take over his post.

Moreover, his capacity for hatred, unfulfilled in the direction of the oppressors, will double back, beyond all reason, on the oppressed; and he will only be satisfied when he has unloaded onto his underlings the injury received from above.

And we must remember that [Hitler and Mussolini's] faithful followers, among them the diligent executors of inhuman orders, were not born torturers, were not (with a few exceptions) monsters: they were ordinary men. Monsters exist, but they are too few in number to be truly dangerous; more dangerous are the common men, the functionaries ready to believe and to act without asking questions.
