 Arendt’s reflections on Eichmann and her concept of the banality of evil have been both influential and controversial (For theorists who believe Arendt’s thoughts are particularly pertinent today, see Bar On 2012 and Bernstein 2008. For a discussion of the controversy see Young-Bruehl 1982). Some theorists take Arendt’s thesis of the banality of evil as a datum to be explained. For instance, social psychologists Stanley Milgram (1974) and Philip Zimbardo (2007) have attempted to explain how social conditions can lead ordinary people to perform evil actions. Others have contested Arendt’s suggestion that ordinary people can be regular sources of evil (see Card 2010; Calder 2003 and 2009).
