At the crossroads of sociology and history, scholars trained in different disciplines write legal history while engaged in a protracted guerilla war that focuses upon notions of normativity. Law and legal development as objects of investigation evoke in the sociology of law the very essence of normativity: what is law if not codified norms, and thus itself subject, perhaps, to norms of development or at least rationality? Conversely, legal historians trained in history departments, who subscribe to the particularizing norms cherished by that discipline, consciously pride themselves on their power to resist the temptations of normativity and, perversely in the view of some, insist upon examining, even celebrating, the deviant, the limiting case, the “exception to the rule.” At different times, one approach or the other has dominated the scholarly literature. Notoriously, the Parsonianism of the 1950s and early 1960s elevated a neo-Weberian normativity to hegemony in legal history as well as in social theory; now the chastened decades at the end of the twentieth and beginning of the twenty-first centuries have tipped the balance within legal history to social history's focus on people, ideas, and experience on the margin, a focus so full of potential to erode general schemes of normative development.
