Even today, few thinkers arouse greater controversy than Hannah Arendt. Dismissed as a left-liberal by some, celebrated by others as the key thinker of politicality itself, what is clear to all sides is that Arendt's rich legacy is not one whose relevance or significance have been exhausted. In particular, as the guest editors of this issue point out, Arendt remains a uniquely significant thinker for any attempt to confront the politics of modernity. We are delighted to present an important collection of essays on and inspired by the work of this singular thinker.
