This book examines the origins, poetics, and capacities of self-reflexive fiction across the globe after World War II. Focusing on three authors’ careers—J. M. Coetzee, Janet Frame, and Philip Roth—it seeks to circumvent the large-scale theoretical paradigms (such as ‘postmodernism’) that have long been deployed to describe this writing. The book does so by developing new terms for discussing the intimacies of metafictional writing, derived from the writing of Miguel de Cervantes and J. L. Borges. The ‘self of writing’ refers to the figure of the author that a writer may imagine exists independently from discourse. The ‘public author as signature’ represents the public understandings of an author that emerge from biography and the author’s corpus itself. The book shows how these figures of authorship are handled by authors, as they draw on the materials offered by their own corpora and communities of readers. Sometimes, this book shows, authors invent distinctively literary ways of adjudicating enduring political debates: the responsibility of a novelist to the political aspirations of a community, the ability of the novel to pursue justice on behalf of others, and the public good that literature serves. Yet this is not a story of unmitigated success: the book also demonstrates how metafiction can be used as a way to close down interpretive schemes and to avoid contributing to public value. Through a close focus on literary environments, the book ultimately gives a finer-grained account of the history of postwar metafiction, and offers new ways of theorizing the relationship between fiction, life-writing, and literary institutions.
