In his Preface to Impure Worlds: The Institution of Literature in the Age of the Novel (2011), Jonathan Arac reflects upon his more than forty-year career as a literary scholar, critic, and historian, tying his own multifaceted project to the inspiring figures of Walter Benjamin and Edward Said, “two exiles, the Jew and the Arab,” whose critical thinking had fueled Arac’s own work. Arac refers especially to his personal experience, first as a university student, then as a professor, but in naming these two thinkers—two radically different, yet somehow mutually resonating cultural critics—Arac also registers the degree to which mixed, hybrid, or indeed “impure” strains of critical inquiry contribute to his own distinctive work. As Arac puts it, the phrase impure worlds “names a zone of inquiry and resource that has shaped my thought for a long time.” Indeed, one might go so far as to say that “purity,” in literature, culture, and society, is inimical to criticism, in as much as literature, a social institution, necessarily reflects and gives form to the heterogeneous elements that make up social experience in a distinct time and place. Benjamin’s kaleidoscopic analysis of the Paris arcades and Said’s contrapuntal, secular criticism offer examples of this critical vocation in practice. So does Arac’s new literary history of the age of the novel, an era in which that form’s heteroglossia and multi-formalism, as Mikhail Bakhtin explored so evocatively, approximates the transformative diversity of the societies and cultures in which it is produced.

With Arac, this commitment to “impurity” underwrites a methodological imperative as well, as he has consistently sought to trouble disciplinary distinctions, making connections between previously separate phenomena and finding hidden affiliations among apparently unrelated writers and texts. It would be difficult to characterize Arac’s body of work, given the sort of professional, disciplinary, or subdisciplinary labels available to us. To be sure, Arac is an Americanist, particularly with respect to nineteenth-century American literature, and he has written influential articles and books on Herman Melville, Nathaniel Hawthorne, Mark Twain, and others. His book-length study of narrative forms in the nineteenth-century United States, which appeared in the monumental Cambridge History of American Literature project edited by Sacvan Bercovitch and was later made available in bookform in 2005 as The Emergence of American Literary Narrative, 1820–1860, confirms his status as one of the most prominent scholars of this period, place, and genre.
