In this chapter, Mariana Valverde offers a historical overview of the discourses underlying modern criminal theory. Modern criminology is rooted in a long tradition of “miserology,” the study of that “hybrid of moral degradation, physical ill health, spatial marginality, and collective despair . . . found among the new urban proletariat.” That history spans Engels’s focus on the “nameless misery” of British factory workers, great 19th-century novelists like Charles Dickens and Victor Hugo, Christian anti-poverty activism, modern welfare dependency discourse, and The Wire. Criminology, however, has lost touch with those deeply situated inquiries. Valverde points to the mid-20th century as a moment of schism between the professional study of crime and crime rates—what we now call criminology—and the study of housing, alcoholism, public health, mental health, and other poverty-related phenomena. But those early miserologists in many ways anticipated today’s resurgent interest in risk, race, social control, and the framing of crime, not as a stand-alone phenomenon, but as one aspect of social marginalization and disadvantage.
