How did Sir William Blackstone divide legal rights in his Commentaries?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

In his influential work, Commentaries on the Laws of England, Sir William Blackstone organized his description of English law into four books, which included a fundamental distinction between the "rights of persons" and the "rights of things".12

Blackstone’s division of legal rights and subjects was structured as follows:

Of the Rights of Persons: This book addressed family and public law.1
Of the Rights of Things: This section provided an outline of real-property law.1
Of Private Wrongs: This volume covered civil liability, courts, and legal procedure.1
Of Public Wrongs: This book served as a study of criminal law.1

While this framework was highly successful and became a standard for legal education, it has been noted by scholars that his distinction between the rights of persons and the rights of things was likely based on a misunderstanding of technical terms found in Roman law, as it implied that inanimate objects could possess rights.3
