This book investigates the fundamental nature of common-law practice in England between 1760 and 1850, challenging the prevailing view that legal theory during this era was primarily driven by abstract theoretical frameworks. Michael Lobban, a scholar of legal history, argues that the work of prominent figures like Blackstone and Bentham has been misinterpreted by those who view them through a purely theoretical lens. Instead, he posits that judicial ideas were deeply rooted in the practical application of moral and political philosophy, evolving through the specific needs and debates of the legal community over these seven decades.

Legal historians frequently cite this work as a significant corrective to traditional interpretations of 18th and 19th-century English law. Scholars note the high level of academic density and the meticulous research Lobban employs to dismantle long-standing misconceptions about the development of common-law jurisprudence.
