Heinz, Roger Brownsword, Roger Cotterrell, and Nicola Lacey. I have chosen Émile Durkheim's Division of Labor in Society (1893). As for many social scientists, Division was part of my introduction to anthropology, especially for its key concepts of collective consciousness and social solidarity. A standard reading of it formulates Durkheim's idea of law as the expression of collective consciousness; however, later circumstances of rereading gave me a sense of his own doubts on this very possibility. As my ethnographic work has increasingly focused on the strategic aggrandizement of federal power in the United States, I have been surprised to find myself repeatedly reaching for Durkheim's book – particularly for its association of the value of social science with the vulnerability of modern society to democratic crisis. - 'Journal of Law and Society, Volume 45, Issue 4, Page 664-678, December 2018.
