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.
