In 20 essays inspired by Hannah Arendt's analysis of crisis-ridden modernity, Wolfgang R. Heuer addresses aspects of depoliticization and the loss of politics, and thus of freedom. The wide-ranging essays are grouped in five sections: When Politics Vanishes, The Call of Responsibility, Images and Emotions, Federations, and From Plurality to Cosmos. They lead to the insight that the crises of our time require a common change of perspective towards ecological and political sustainability, the unity of Cosmos and Republic .
