Modern philosophy continues to grapple with the idea of subjectivity–and, as the concept of subjectivity has consequently been repeatedly refined and redefined, the struggle has spread to the ways we conceive of sovereignty, collectivity, nationality, and identity as a result. Yet, in the absence of an authoritative account of these central philosophical concepts, exciting new ways of thinking have emerged which continue to develop and evolve. Epidemic Subjects–Radical Ontology brings together a renowned team of contributors, including Levi Bryant, Angela Melitopoulos, and Susan Stryker, who together forge a radically inclusive definition of subjectivity. Drawing on Gilles Deleuze and Felix Guattari’s concept of the girl as a heuristic device for examining modern society and its foundations, they tie together recent trends in philosophy and offer a concrete way forward from the conception of the thing or object privileged by new materialism, speculative realism, and other theories of subjectivity.
