Life is a system of recurrent pairs, the poison and the antidote being eternally packaged together by some considerate heavenly druggist. - Hannah Arendt

Kant ... discovered “the scandal of reason,” that is the fact that our mind is not capable of certain and verifiable knowledge regarding matters and questions that it nevertheless cannot help thinking about.

The Nazis were ‘convinced that evil-doing in our time has a morbid force of attraction,’ Bolshevik assurances inside and outside Russia that they do not recognize ordinary moral standards have become a mainstay of Communist propaganda, and experience has proven time and again that the propaganda value of evil deeds and general contempt for moral standards is independent of mere self-interest, supposedly the most powerful psychological factor in politics.

The trouble with Eichmann was precisely that so many were like him, and that the many were neither perverted nor sadistic, that they were, and still are, terribly and terrifyingly normal. From the viewpoint of our legal institutions and of our moral standards of judgment, this normality was much more terrifying than all the atrocities put together, for it implied — as had been said at Nuremberg over and over again by the defendants and their counsels — that this new type of criminal, who is in actual fact hostis generis humani, commits his crimes under circumstances that make it well-nigh impossible for him to know or to feel that he is doing wrong.
