“Evil comes from a failure to think.” – Hannah Arendt
Although The Origins of Totalitarianism was Arendt’s first influential work, Eichmann in Jerusalem may be her most enduring legacy. In 1961 she traveled to Jerusalem to cover the trial of Adolf Eichmann, the Nazi official who had organized the mass deportation of Jews to the death camps by handling the trains, the schedules, the logistics of genocide.
She expected to find a monster. What she found unsettled her far more: an ordinary man who blew his nose into a handkerchief, spoke in worn-out clichés, and understood himself to be simply doing his job, and doing it well. He did not seem to have a burning hatred for Jews or master plan. He had simply stopped asking what the job actually was.
From this came her most famous phrase “the banality of evil.” In saying this, she not mean that evil is harmless, or that Eichmann’s crimes were small. Rather, it means that the machinery of mass murder did not require monsters to run it. It required clerks. It required ordinary people who followed orders, advanced their careers, and never let themselves think about where the trains were going. As she wrote, the most terrible thing about Eichmann was not that he was a monster, but that he was “terribly and terrifyingly normal.”
Monsters rarely look like monsters. They look like people trying to do their job well. That’s why Arendt’s lesson is so controversial and hard to take: the worst things get done not by people who decided to be cruel, but by people who decided not to think about it. There were never enough monsters to do all of it. There didn’t need to be. All there needs to be is people who refuse to question.
But if evil runs on people not thinking, then thinking is how it stalls. The clerk who stops to ask where the trains are going, the colleague who speaks out against something that feels wrong, the one person in the room who refuses to go along: each is a wrench in the machine. It doesn’t take a hero. It takes someone willing to think when going along would be easier. The same ordinariness that makes evil possible is what makes stopping it possible too. That part is up to us.
