The fifth book in the series offers an historical and conceptual account of the criminal law, as it has developed in England and spread to common law jurisdictions around the world. It traces how and why criminal law has come to be accorded with a central role in securing civil order in modernity, and justifies who and what should be treated as criminal under the law. Farmer argues that the emergence of the modern state in which criminal law is recognized as an instrument of government is a result of the distinct body of rules which have emerged from the modern criminal law.
