skillful industry is the soul of an active life. But industry should have her just reward. That reward is property, for of useful and active industry, property is the natural result.” From this simple reasoning he is able to present the conclusion that exclusive, as opposed to communal property, is to be preferred. Wilson does, however, give a survey of communal property arrangements in history, not only in colonial Virginia but also ancient Sparta. Property rights There are two main views on the right to property, the traditional view and the bundle of rights view. The traditionalists believe that there is a core, inherent meaning in the concept of property, while the bundle of rights view states that the property owner only has bundle of permissible uses over the property. The two views exist on a spectrum and the difference may be a matter of focus and emphasis. William Blackstone, in his Commentaries on the Laws of England, wrote that the essential core of property is the right to exclude. That is, the owner of property must be able to exclude others from the thing in question, even though the right to exclude is subject to limitations. By implication, the owner can use the thing, unless another restriction, such as zoning law, prevents it. Other traditionalists argue that three main rights define property: the right to exclusion, use and transfer. An alternative view of property, favored by legal realists, is that property simply denotes a bundle of rights defined by law and social policy. Which rights are included in the bundle known as property rights, and which bundles are preferred to which others, is simply a matter of policy. Therefore, a government can prevent the building of a factory on a piece of land, through zoning law or criminal law, without damaging the concept of property. The "bundle of rights" view was prominent in academia in the 20th century and remains influential today in American law. Priority Different parties may claim a competing interest in the same property by mistake or by fraud, with the claims being inconsistent of each other. For example, the party creating or transferring an interest may have a valid title, but may intentionally or negligently create several interests wholly or partially inconsistent with each other. A court resolves the dispute by adjudicating the priorities of the interests. Property rights and rights to people Property rights
