Gracefully traversing a wide range of discourses––including literature, evolutionary theory, early anthropology, Marxism, feminism, and psychoanalysis––Weinbaum traces a genealogy of the race/reproduction bind within key intellectual formations of the late nineteenth and twentieth centuries. She examines two major theorists of genealogical thinking-Friedrich Nietzsche and Michel Foucault-and unearths the unacknowledged ways their formulations link race and reproduction. She explores notions of kinship and the replication of racial difference that run through Charlotte Perkins Gilman’s work; Marxist thinking based on Friedrich Engel’s The Origin of the Family; Charles Darwin’s theory of sexual selection; and Sigmund Freud’s early studies on hysteria. She also describes W. E. B. Du Bois’s efforts to transcend ideas about the reproduction of race that underwrite citizenship and belonging within the United States. In a coda, Weinbaum brings the foregoing analysis to bear on recent genomic and biotechnological innovations.
