Commentaries on the Laws of England

Summary

Sir William Blackstone's Commentaries on the Laws of England, published at Oxford by the Clarendon Press in four volumes between 1765 and 1769, grew out of the lectures he gave at Oxford from 1753 and as first Vinerian Professor from 1758. It was the first full account of English law written for educated readers rather than for practising lawyers, arranged as a reasoned system instead of a collection of cases. Volume I treats the Rights of Persons, II the Rights of Things (property), III Private Wrongs (civil remedies and procedure) and IV Public Wrongs (crimes). The library text is a selection: the Introduction and Book I from the first edition of 1765. Books II to IV are not included. The Introduction has four sections. The first, Blackstone's inaugural Vinerian lecture of 25 October 1758, argues that every English gentleman, as juror, magistrate, legislator or landowner, ought to know the laws of his country, and that the universities should teach them. The second, on the nature of laws in general, describes law as a rule of action prescribed by a superior: the law of nature, coeval with mankind and dictated by God, and the revealed law of Scripture are the foundations, and no human law should contradict them. The third distinguishes the unwritten common law, known through the decisions of courts and the customs of the realm, from statute law, and describes how equity and the civil and canon laws fit in. The fourth surveys the countries subject to English law: Wales, Scotland after the Union, Ireland, the islands, and the American plantations, which he classes as conquered or ceded lands where the common law did not automatically apply. Book I begins with the absolute rights of individuals: personal security (life, limbs, body, health and reputation), personal liberty, and private property, protected by auxiliary rights such as Parliament, limits on the royal prerogative, access to the courts, petition, and arms for defence. Chapter 2 describes Parliament, whose power Blackstone calls so great that what it does no authority upon earth can undo. Chapters 3 to 8 treat the king: his title, family, councils, duties, prerogative (the king can do no wrong, and never dies) and revenue, which includes the custody of idiots and lunatics. Chapters 9 to 13 describe magistrates, aliens and natives, the clergy, the civil state of nobility and commons, and the army and navy. The private relations follow: master and servant, husband and wife (the doctrine of coverture, by which husband and wife are one person in law), parent and child, and guardian and ward. The final chapter treats corporations. The Commentaries were reprinted in Philadelphia in 1771 to 1772 and became the chief textbook of law in the young United States, read by the founding generation and by later students including Abraham Lincoln.

Top Lessons

  • Human law rests on natural and revealed law

    Blackstone begins his account of English law with God. The law of nature, dictated by God and binding everywhere, and the revealed law of Scripture are the two foundations; human laws regulate matters left indifferent and must not contradict them. Positive law, on this view, is a servant of a higher order.

  • Three absolute rights of every Englishman

    Book I, ch. 1 names personal security, personal liberty and private property as the absolute rights that society exists to protect. Blackstone shows that these rights would be words only without auxiliary rights: Parliament, limits on the crown, the courts, petition and arms. Rights need institutions to guard them.

  • Law as an inheritance of precedent

    The common law is not a code enacted at a single time but a body of customs known through the decisions of judges, who are bound to follow precedent unless it is clearly absurd or unjust. Blackstone presents this as a source of stability and of liberty, since no single ruler can remake the law at will.

  • Every gentleman should know the law

    In his opening lecture Blackstone argues that knowledge of law belongs to liberal education, because jurors, magistrates, legislators and landowners all exercise legal power. A free people that does not understand its laws cannot keep them.

  • The law as guardian of those who cannot guard themselves

    Chapter 8's account of idiots and lunatics shows the crown acting as trustee for people unable to manage their affairs, preserving their property for them and forbidding the next heir to be the keeper of a lunatic, since he would gain by the person's death. Blackstone presents this protective duty as part of the king's office as general conservator of his people.

Medical Lens

Book I is a primary source for the eighteenth-century law of insanity and incapacity. Chapter 8 distinguishes the idiot, without understanding from birth, whose lands the crown takes into ward for life, from the lunatic or person non compos mentis, who has lost reason by disease, grief or accident and whose estate the crown holds only as trustee in case of recovery. Blackstone notes the old association of lunacy with lucid intervals and the moon, includes under non compos mentis persons under frenzies and those who lose their intellects by disease, and treats a person born deaf, dumb and blind as legally like an idiot because the senses supply the mind with ideas, an echo of Lockean psychology. The Lord Chancellor's commission to inquire into a person's state of mind, decided by a jury, and the appointment of a committee of the person, but never the next heir, are early procedural safeguards in incapacity law. Chapter 1 defines personal security to include health, and states that the law protects life from quickening, so that killing a quick child by potion or blows was by ancient law homicide and in Blackstone's day a heinous misdemeanour. These are legal categories of 1765, not clinical diagnoses.

  • Book I, ch. 8 (eighteenth branch of the king's ordinary revenue)

    Idiots and natural fools distinguished from lunatics; the writ de idiota inquirendo and the jury test of a person's understanding.

  • Book I, ch. 8

    Non compos mentis caused by disease, grief or accident; lucid intervals; persons under frenzies or losing intellect by disease; the crown as trustee for their recovery.

  • Book I, ch. 8

    The Lord Chancellor's commission of lunacy and the rule that the next heir may not be committee of the person.
