Property

Property refers both to a system of legally enforceable rights over valuable assets and to the assets themselves. Depending on what is owned, an owner may be entitled to consume, alter, share, rent, sell, exchange, transfer, give away, destroy, or exclude others from doing these things. In economics and political economy, property takes four broad forms: private, public, collective, and common. Ownership can be shared by multiple parties, equally or unequally, under simple or complex agreements; to distinguish ownership from easement or rent, each party’s will regarding the property must be clearly defined and unconditional. Parties may require unanimous consent, or each may act alone when no dispute arises.

In American law, the first Restatement defines property as anything—tangible or intangible—that creates a legal relationship between persons and the State, enforcing a possessory interest or legal title. This mediating link between individual, property, and State is called a property regime. In sociology and anthropology, property is often seen as a relationship between two or more individuals and an object, where at least one holds a bundle of rights over it. The distinction between collective and private property is sometimes considered misleading, as different individuals often hold different rights over the same object.

Types of property include real property (land and improvements on it), personal property (physical possessions), private property (owned by legal persons, businesses, or individuals), public property (state-owned or publicly available), and intellectual property (exclusive rights over artistic creations and inventions), though the last is not always widely recognized or enforced. An article of property may have both physical and incorporeal parts. A title or right of ownership establishes the relation between the property and others, assuring the owner the right to dispose of it as they see fit. The unqualified term “property” often refers specifically to real property.

Property is typically defined by local sovereignty codes and protected wholly or partially by that entity, with the owner responsible for any remaining protection. Standards of proof for ownership are also set by local sovereignty, which plays a somewhat managerial role. Some philosophers argue property rights arise from social convention; others find justifications in morality or natural law. Various disciplines—law, economics, anthropology, sociology—treat the concept systematically, but definitions vary, especially regarding contracts. Positive law defines such rights, and the judiciary can adjudicate and enforce them.

Adam Smith (1723–1790) held that the expectation of profit from “improving one’s stock of capital” rests on private-property rights. Capitalism assumes property rights encourage holders to develop property, generate wealth, and allocate resources efficiently through markets. This has led to the modern conception of property as a right enforced by positive law, expected to produce more wealth and better living standards. Yet Smith also criticized property laws for fostering inequality: “Wherever there is a great property, there is great inequality… Civil government, so far as it is instituted for the security of property, is in reality instituted for the defense of the rich against the poor.”

In his 1881 text *The Common Law*, Oliver Wendell Holmes described property as having two fundamental aspects: possession (control over a resource based on the practical inability to contradict the possessor’s ends) and title (the expectation that others will recognize rights to control resources even when not in possession). He elaborated on their differences and proposed a history of how they became attached to persons rather than families or entities like the church.

Classical liberalism subscribes to the labor theory of property: individuals own their own lives, so they must acknowledge the products of those lives, which can be traded freely. John Locke wrote, “Every man has a property in his person. This nobody has a right to, but himself,” and “The reason why men enter into society is the preservation of their property.” Frédéric Bastiat stated, “Life, liberty, and property do not exist because men have made laws. On the contrary, it was the fact that life, liberty, and property existed beforehand that caused men to make laws in the first place.” Conservatism holds that freedom and property are closely linked—property guarantees or causes freedom—and that the more widespread private property is, the more stable and productive a state or nation becomes.
