As far as the Jews were concerned, the transformation of the "crime" of Judaism into the fashionable "vice" of Jewishness was dangerous in the extreme. Jews had been able to escape from Judaism into conversion; from Jewishness there was no escape. A crime, moreover, is met with punishment; a vice can only be exterminated.

There is, therefore, a temptation to return to an explanation which automatically discharges the victim of responsibility: it seems quite adequate to a reality in which nothing strikes us more forcefully than the utter innocence of the individual caught in the horror machine and his utter inability to change his fate. Terror, however, is only in the last instance of its development a mere form of government. In order to establish a totalitarian regime, terror must be presented as an instrument for carrying out a specific ideology; and that ideology must have won the adherence of many, and even a majority, before terror can be stabilized. The point for the historian is that the Jews, before becoming the main victims of modern terror, were the center of Nazi ideology. And an ideology which has to persuade and mobilize people cannot choose its victim arbitrarily.

As for the comparatively small class of violent crimes against persons, unconnected with any idea of gain, they were almost wholly confined, even in your day, to the ignorant and bestial; and in these days, when education and good manners are not the monopoly of a few, but universal, such atrocities are scarcely ever heard of.

Caution in handling generally accepted opinions that claim to explain whole trends of history is especially important for the historian of modern times, because the last century has produced an abundance of ideologies that pretend to be keys to history but are actually nothing but desperate efforts to escape responsibility.
