『イェルサレムのアイヒマン』（ペンギン・クラッシクス版）へのAmos Elon*1の序文、”The Excommunication of Hannah Arendt”(pp.vii-xxiii)から１パラグラフを切り取っておく；

In The Origins of Totalitarianism she still held on to a Kantian notion of radical evil, the evil that, under the Nazis, corrupted the basis of moral law, exploded legal categories, and defied human judgment. In Eichmann in Jerusalem, and in the bitter controversies about it that followed, she insisted that only good had any depth. Good can be radicval; evil can never be radical, it can only be extreme, for it possessses neither depth nor any demonic dimension yet—and this is its horror!--it can spread like a fungus over the surface of the earth and lay waste the entire world. Evil comes from a failure to think. It defies thought for as soon as thought tries to engage itself with evil and examine the premises and principles from which it originates, it is frustrated because it finds nothing there. That is the banality of evil. (pp.xiii-xiv)
