Hannah Arendt’s life describes a tragically typical twentieth century trajectory.  Born in Germany and, fleeing the Nazis, she ended up in the United States, where she died in 1975.  As a philosopher – a title she disclaimed – she insisted on the importance of thinking in the world and not trying to be above it and she thought that understanding the richness and variety of the world was more important than attaining a consistent view of it. This week, we look at a very worldly thinker.
