Abstract
Many have been struck by Hannah Arendt’s remarks on loneliness in the concluding pages of The Origins of Totalitarianism, but very few have attempted to deal with the remarks in any systematic way. What is especially striking about this state of affairs is that the remarks are crucial to the account contained therein, as they betray a view of agency that undergirds the rest of the account. This article develops Arendt’s thinking on loneliness throughout her corpus, showing how loneliness is connected to thoughtlessness. In so doing, the article also suggests a connection between Arendt’s notion of loneliness and Stanley Cavell’s notion of skepticism. This connection, it is argued, allows us not only fully to answer a question Arendt leaves unaddressed (the cause loneliness), but also allows us to see how we, as agents and users of language, are perpetually prone to loneliness.
