Underpinned by a concern with democratic futurity, this chapter notes that in the face of perceived threats to human existence, economists, urban planners, and other social theorists have turned to a focus on resilience – itself a commitment to ‘going on together’ – rather than prevention. Predicated upon an acceptance of the inevitability of potentially catastrophic events, practices of resilience seek to maintain core system functions in the face of disasters that might threaten them. It notes that although the literature on resilience has proliferated in other fields, little to no attention has been paid to the concept in political theory. Addressing this lacuna, it argues that certain theories of resilience are predicated upon an unacknowledged tragic worldview whose self-conscious cultivation through a tragic mode of mourning would better achieve its goals by serving as a source of democratic pedagogy in the face of loss. Presenting Thucydides’ History of the Peloponnesian War as just such a form of tragic mourning for Athens, the book concludes with an account of the ways in which, as a form of textual mourning, the History offers an example of a non-ritualized response to loss that might best serve an age of democratic atomism and political estrangement.
