Jeff Martin's book is a very welcome volume in Cornell's ground-breaking Police/ Worlds series on security, crime and governance, and this book offers the kind of sustained intellectual analysis of police that I wish I had been able to read as a neophyte comparative criminological researcher prior to visiting Taiwan nearly twenty years ago. Sentiment, Reason, and Law does precisely that, and invites us to consider what concepts, contexts and forms are most pertinent for building a reflective relation to the present. Martin spent almost a decade living in Taiwan, and this book is a fittingly rich intellectual legacy of his sojourn on that enchanted island.(The China Quarterly) Jeffrey T. Martin's book is a masterful addition to the ethnographic literature both on the anthropology of the state and for the anthropology of police and policing. The strength of the book lies in the in-depth fieldwork that, combined with a refusal of presentism, enables Martin to distance himself from culturalism and present Taiwanese police and its work as part of a historical process. Thus, this book can be highly recommended as a contribution to the anthropology of policing and of the state.(Polar)
