Anonymous Connections asks how the Victorians understood the ethical, epistemological, and biological implications of social belonging and participation. Specifically, Tina Choi considers the ways nineteenth-century journalists, novelists, medical writers, and social reformers took advantage of spatial frames-of-reference in a social landscape transforming due to intense urbanization and expansion. New modes of transportation, shifting urban demographics, and the threat of epidemics emerged during this period as anonymous and involuntary forms of contact between unseen multitudes. While previous work on the early Victorian social body have tended to describe the nineteenth-century social sphere in static political and class terms, Choi’s work charts new critical terrain, redirecting attention to the productive—and unpredictable—spaces between individual bodies as well as to the new narrative forms that emerged to represent them. Anonymous Connections makes a significant contribution to scholarship on nineteenth-century literature and British cultural and medical history while offering a timely examination of the historical forebears to modern concerns about the cultural and political impact of globalization.
