Is owning something a single right or a whole bundle of them?
Lawyers disagree about what ownership really is. One camp, following William Blackstone, says its core is the right to keep others out. Another, popular with twentieth-century legal realists, sees only a bundle of permitted uses that governments can reshape through zoning or criminal law without destroying property itself.
In law, property usually means the rights someone holds over a thing rather than the thing. Most systems split it into real property, meaning land, and personal property, which may include intangible assets such as intellectual property. Property rights bind everyone, whereas contractual rights bind only particular people, though the two overlap; selling land creates both a right to sue for damages and a right over the land. A licence, even one granted by contract, usually gives no property interest at all.
Continental systems draw heavily on Rome. Roman jurists pictured dominium as a single, near-absolute right to use something, take its fruits and dispose of it. They separated ownership from possession, meaning physical control plus the intention to keep a thing, and protected possessors in their own right so that people would not settle disputes by force. Ownership could be gained by seizing ownerless things, by long possession, or by simple delivery, which eventually replaced a formal ceremony once needed for land, slaves and draught animals. Justinian's codification later shaped the French and German civil codes. English law, by contrast, developed ownership in a fragmented way through two court systems, equity and common law.
Philosophers have argued over why anyone owns anything. John Locke claimed that people mix their labour with the world and so make things theirs, provided enough good land is left for others. The American justice James Wilson, in 1790 and 1791, treated protection of property among other natural rights as the main job of government. Marx attacked private property, though Marxist–Leninist states such as China and the Soviet Union kept some form of it.
History shows who was shut out. Enslaved people were treated as property themselves, and Jews in England and married women in Western countries were long barred from owning it. Today most property belongs to corporations.
