Abstract: Hannah Arendt's famous "the evil of banality" means that, evil comes from people忆s thoughtlessness and
no judgment. Arendt believes that such kind of evil needs to be restrained or even eliminated through thinking.
Arendt's criticism of evil is true to the point, but there are still deficiencies in the theoretical construction of
thinking. This paper will sort out the background and connotation of the evil of banality, the thinking which
overcomes it, and discuss the dilemma of thinking. At the end of the paper, the paper will tentatively put forward
the outlet of thinking

Key words: Hannah Arendt, the evil of banality, thinking, judgment, common sense
