Duff's The Realm of Criminal Law offers an appealing moral reconstruction of the criminal law.
Alec Walen, Rutgers University, Criminal Law and Philosophy
R.A. Duff's The Realm of the Criminal Law advances the literature on criminalization by providing the most thorough exploration and defence yet provided of the intuitively attractive idea that criminalization is properly limited to public wrongs only [...] The international community of criminal law theory owes Antony a huge debt. He is not only one of the preeminent scholars in this field, he has also done so much to build and shape it as a community. The Realm of Criminal Law Theory is a civil order in which Antony has played a leading role. And while Antony's politics are avowedly egalitarian, academic esteem is not, and he is surely one of the high priests of that community.
Patrick Tomlin, University of Warwick, Criminal Law and Philosophy
In his magnificent new work, The Realm of Criminal Law, Antony Duff has important things to say about a host of central issues in the philosophy of criminal law.
